Drżenie rąk
Diagnostyka i diagnoza

Drżenie rąk (tremor) to mimowolne, rytmiczne drgania, które mogą mieć różne etiologie neurologiczne, w tym drżenie samoistne (ET), chorobę Parkinsona, drżenie móżdżkowe czy polekowe. Kluczowa jest szczegółowa diagnostyka kliniczna obejmująca ocenę warunków występowania drżenia (spoczynkowe, posturalne, kinetyczne), lokalizację, częstotliwość (niska ~4 Hz, średnia 4-8 Hz, wysoka >8 Hz) oraz symetrię. Test spirali Archimedesa umożliwia ocenę charakterystyki drżenia, a badania dodatkowe, takie jak badania laboratoryjne (hormony tarczycy, elektrolity, ceruloplazmina), obrazowe (MRI, CT, SPECT z DaTSCAN) oraz elektrofizjologiczne (EMG, akcelerometria), wspomagają różnicowanie przyczyn. Drżenie spoczynkowe jest patognomoniczne dla parkinsonizmu, natomiast drżenie intencyjne wskazuje na uszkodzenie móżdżku. W diagnostyce różnicowej należy uwzględnić także stwardnienie rozsiane, dystonię, chorobę Wilsona, udar mózgu oraz zaburzenia metaboliczne i polekowe.

Diagnoza drżenia rąk

Drżenie rąk (tremor) to mimowolne, rytmiczne drgania lub drżenie rąk, które mogą być objawem różnych stanów neurologicznych. Prawidłowa diagnoza drżenia rąk jest kluczowa, ponieważ istnieje wiele potencjalnych przyczyn tego objawu, a właściwe rozpoznanie umożliwia wdrożenie odpowiedniego leczenia. Drżenie rąk może być zarówno objawem samoistnym, jak i występować jako część innych zaburzeń neurologicznych.12

Drżenie nie jest stanem zagrażającym życiu, jednak może znacząco upośledzać codzienne funkcjonowanie i jakość życia pacjenta. Szacuje się, że drżenie samoistne, będące najczęstszą przyczyną drżenia, dotyka około 1% ogólnej populacji na świecie oraz około 5% osób powyżej 60. roku życia.1

Badanie kliniczne

Podstawą diagnozy drżenia rąk jest dokładne badanie kliniczne oraz szczegółowy wywiad medyczny. Pacjenci z nowo rozpoznanym drżeniem powinni mieć przeprowadzony kompleksowy przegląd przyjmowanych leków (zarówno przepisanych na receptę, jak i dostępnych bez recepty), ze szczególnym uwzględnieniem leków, które rozpoczęto przyjmować przed wystąpieniem drżenia.34

Podczas badania lekarz zwraca uwagę na następujące aspekty drżenia:54

  • Kiedy występuje drżenie – podczas spoczynku, w pozycji statycznej, przy wykonywaniu ruchów
  • Lokalizacja drżenia – które części ciała są objęte
  • Częstotliwość i nasilenie drżenia
  • Symetryczność drżenia
  • Czynniki nasilające lub łagodzące drżenie

Lekarz może poprosić pacjenta o wykonanie różnych zadań, takich jak wyciągnięcie rąk przed siebie, dotknięcie nosa palcem czy napisanie kilku słów. Obserwacja, jak drżenie zmienia się podczas tych czynności, może pomóc w określeniu jego rodzaju i przyczyny.56

Klasyfikacja drżenia

Pierwszym krokiem w diagnostyce drżenia jest jego kategoryzacja na podstawie warunków aktywacji, rozkładu topograficznego i częstotliwości. Rozróżnia się kilka głównych typów drżenia:34

  • Drżenie spoczynkowe – występuje, gdy mięśnie są w stanie spoczynku; charakterystyczne dla choroby Parkinsona
  • Drżenie posturalne – pojawia się, gdy kończyna jest utrzymywana przeciwko sile grawitacji
  • Drżenie kinetyczne/intencyjne – występuje podczas wykonywania ruchów celowych
  • Drżenie fizjologiczne – naturalne drżenie, które może być nasilone przez stres, zmęczenie, leki

Drżenie spoczynkowe jest praktycznie patognomoniczne dla parkinsonizmu, podczas gdy drżenie intencyjne często wskazuje na uszkodzenie móżdżku.3

Test spirali Archimedesa

Jednym z narzędzi diagnostycznych, z których korzystają lekarze do oceny drżenia, jest test spirali lub test spirali Archimedesa. Podczas tego testu pacjent jest proszony o narysowanie nieprzerwanej spirali, raz lewą, raz prawą ręką.6

Test spirali Archimedesa jest ważny, ponieważ pozwala uchwycić częstotliwość, kierunek i amplitudę drżenia. Powstała spirala może dostarczyć dowodów na rodzaj i nasilenie drżenia. To zadanie rysunkowe, wraz z innymi danymi klinicznymi i testami, może pomóc w ustaleniu diagnozy i planowaniu leczenia drżenia.6

Badania diagnostyczne w rozpoznawaniu drżenia rąk

Chociaż diagnoza drżenia opiera się głównie na badaniu klinicznym, w celu wykluczenia innych chorób mogących powodować podobne objawy, lekarz może zlecić dodatkowe badania diagnostyczne.71

Badania laboratoryjne

Badania krwi i moczu mogą pomóc wykluczyć inne przyczyny drżenia:289

  • Badanie poziomu hormonów tarczycy – nadczynność tarczycy może powodować drżenie
  • Badanie poziomu elektrolitów – zaburzenia elektrolitowe mogą przyczyniać się do drżenia
  • Testy funkcji wątroby i nerek
  • Poziom glukozy we krwi – hipoglikemia może powodować drżenie
  • Poziom ceruloplazminy w surowicy i wydalanie miedzi w moczu – wykluczenie choroby Wilsona, szczególnie u młodych pacjentów z drżeniem

Badania obrazowe

Badania obrazowe pomagają wykluczyć uszkodzenia strukturalne mózgu, które mogłyby być przyczyną drżenia:217

  • Rezonans magnetyczny (MRI) – pomaga wykluczyć zmiany strukturalne i zapalne (w tym stwardnienie rozsiane) oraz chorobę Wilsona. MRI powinno być wykonane, jeśli drżenie ma nagły początek lub stopniową progresję
  • Tomografia komputerowa (CT) – może być alternatywą dla MRI w wykluczeniu zmian strukturalnych
  • Tomografia emisyjna pojedynczego fotonu (SPECT) – z użyciem ioflupanu I-123 (DaTSCAN) pomaga określić, czy występuje utrata neuronów dopaminergicznych, jak ma to miejsce w chorobie Parkinsona
  • Tomografia emisyjna pozytonowa (PET) – może być stosowana do wykluczenia innych przyczyn drżenia

W szczególnie trudnych przypadkach SPECT umożliwiający wizualizację integralności szlaków dopaminergicznych w mózgu może być przydatny w diagnostyce choroby Parkinsona.74

Badania elektrofizjologiczne

Elektrofizjologiczne badania mogą pomóc ocenić aktywność mięśni i odpowiedź nerwowo-mięśniową:289

  • Elektromiografia (EMG) – mierzy mimowolną aktywność mięśni i odpowiedź mięśni na stymulację nerwową
  • Akcelerometria – może być używana do oceny częstotliwości, rytmiczności i amplitudy drżenia, ale nie jest częścią rutynowej oceny

W 2017 roku badacze opisali elektrofizjologiczną miarę, która może odróżnić drżenie w chorobie Parkinsona od drżenia samoistnego z wysoką dokładnością diagnostyczną. Wskaźnik stabilności drżenia, uzyskany z pomiarów kinematycznych aktywności drżeniowej, osiągnął maksymalną czułość, swoistość i dokładność na poziomie odpowiednio 95%, 95% i 92%.10

Rozróżnienie drżenia samoistnego od innych rodzajów drżenia

Drżenie samoistne (ET) jest najczęstszą przyczyną drżenia rąk, jednak istnieje wiele innych stanów, które mogą powodować podobne objawy. Prawidłowe rozróżnienie typu drżenia jest kluczowe dla właściwego leczenia.1112

Drżenie samoistne vs. choroba Parkinsona

Drżenie w chorobie Parkinsona i drżenie samoistne różnią się kilkoma kluczowymi cechami:131415

  • Drżenie samoistne:
    • Występuje głównie podczas aktywności (drżenie posturalne i kinetyczne)
    • Zwykle obejmuje obie strony ciała
    • Często dotyczy rąk, głowy i głosu
    • Brak innych objawów motorycznych
  • Drżenie w chorobie Parkinsona:
    • Występuje głównie w spoczynku
    • Zaczyna się jednostronnie
    • Towarzyszą mu inne objawy motoryczne: sztywność mięśniowa, spowolnienie ruchowe (bradykinezja)
    • Rzadko obejmuje głowę

W przypadku wątpliwości diagnostycznych, badanie DaTSCAN może pomóc odróżnić drżenie samoistne od drżenia w chorobie Parkinsona, uwidaczniając prawidłową lub nieprawidłową dystrybucję transporterów dopaminy.1610

Drżenie samoistne vs. drżenie fizjologiczne

Drżenie fizjologiczne jest normalnym zjawiskiem, które może być nasilone przez różne czynniki:1718

  • Nasilone drżenie fizjologiczne:
    • Może być wywołane przez stres, zmęczenie, leki, kofeinę, alkohol
    • Zazwyczaj ma mniejszą amplitudę niż drżenie samoistne
    • Ustępuje po usunięciu czynnika wyzwalającego
  • Drżenie samoistne:
    • Jest bardziej nasilone i trwałe
    • Zwykle postępuje z wiekiem
    • Często występuje rodzinnie

Inne rodzaje drżenia

W diagnostyce różnicowej drżenia rąk należy uwzględnić również inne typy drżenia:18191720

  • Drżenie móżdżkowe – może towarzyszyć zaburzeniom wpływającym na neurony móżdżku (np. ataksje rdzeniowo-móżdżkowe) lub połączenia aferentne lub eferentne móżdżku (np. stwardnienie rozsiane, udary pnia mózgu)
  • Drżenie dystoniczne – występuje u pacjentów z dystonią, może również występować w tej samej części ciała, która jest dotknięta dystonią
  • Drżenie Holmesa – rzadkie, zwykle występuje z opóźnieniem po uszkodzeniu strukturalnym wzgórza móżdżkowego, jądra zębatego lub środkowego pedunkułu móżdżku
  • Drżenie ortostatyczne – nietypowe drżenie, które wpływa na tułów i nogi i jest specyficznie wyzwalane przez stanie
  • Drżenie polekowe – może być wywołane przez różne leki, w tym leki psychiatryczne, przeciwpadaczkowe, przeciwastmatyczne i immunosupresyjne
  • Drżenie metaboliczne – związane z zaburzeniami metabolicznymi, takimi jak nadczynność tarczycy

Diagnostyka różnicowa drżenia rąk

W diagnostyce różnicowej drżenia rąk należy uwzględnić wiele stanów klinicznych, które mogą powodować podobne objawy. Poniżej przedstawiono główne schorzenia, które należy rozważyć:212223

Choroby neurologiczne

  • Choroba Parkinsona – charakteryzuje się drżeniem spoczynkowym, sztywnością mięśniową i bradykinezją
  • Stwardnienie rozsiane – drżenie może być jednym z objawów uszkodzenia układu nerwowego
  • Dystonia – może występować z drżeniem w tych samych częściach ciała
  • Zespoły parkinsonowskie plus – grupa chorób neurologicznych z objawami podobnymi do choroby Parkinsona, ale o innej patofizjologii
  • Choroba Wilsona – rzadka choroba genetyczna związana z zaburzeniami metabolizmu miedzi, może powodować drżenie
  • Udar mózgu – może prowadzić do drżenia jako następstwa uszkodzenia określonych obszarów mózgu
  • Ataksje rdzeniowo-móżdżkowe – grupa chorób dziedzicznych wpływających na móżdżek i rdzeń kręgowy

Zaburzenia metaboliczne i endokrynologiczne

  • Nadczynność tarczycy – podwyższony poziom hormonów tarczycy może powodować drżenie
  • Hipoglikemia – niski poziom glukozy we krwi może wywoływać drżenie
  • Zaburzenia elektrolitowe – zaburzenia równowagi elektrolitowej mogą przyczyniać się do drżenia

Drżenie indukowane lekami i substancjami

  • Leki – wiele leków może powodować drżenie jako działanie niepożądane, w tym:
    • Leki psychiatryczne
    • Leki przeciwpadaczkowe
    • Leki przeciwastmatyczne
    • Leki immunosupresyjne
  • Substancje psychoaktywne:
    • Kofeina
    • Alkohol (szczególnie podczas odstawienia)
    • Nikotyna

Inne przyczyny drżenia

  • Stres i lęk – mogą powodować przejściowe drżenie
  • Zmęczenie – może nasilać drżenie fizjologiczne
  • Hipertermia – podwyższona temperatura ciała może powodować drżenie
  • Drżenie czynnościowe (psychogenne) – może naśladować organiczne zespoły drżenia

Ocena drżenia u szczególnych grup pacjentów

Diagnoza drżenia może być szczególnie wymagająca w niektórych grupach pacjentów, gdzie standardowe podejście diagnostyczne może wymagać modyfikacji.4

Drżenie u dzieci

Diagnoza drżenia u dzieci jest stosunkowo słabo poznana. Różne stany genetyczne są związane z drżeniem u dzieci, w tym:424

  • Rdzeniowy zanik mięśni
  • Choroby mitochondrialne
  • Choroba Huntingtona
  • Zespół łamliwego chromosomu X

Podobnie jak u dorosłych, drżenie samoistne może również występować u dzieci. Diagnoza opiera się na dokładnym badaniu neurologicznym. Badania laboratoryjne i obrazowe mogą być konieczne do wykluczenia innych zaburzeń.24

Drżenie u osób starszych

U osób starszych drżenie występuje częściej, a diagnostyka różnicowa powinna uwzględniać:2526

  • Zwiększone prawdopodobieństwo chorób neurozwyrodnieniowych, takich jak choroba Parkinsona
  • Większe ryzyko drżenia polekowego ze względu na polipragmazję
  • Współistniejące choroby mogące wpływać na drżenie (choroby naczyniowe, metaboliczne)

Ocena drżenia u osób starszych powinna obejmować dokładny przegląd przyjmowanych leków, ocenę zaburzeń poznawczych oraz badania obrazowe w celu wykluczenia zmian naczyniowych i neurozwyrodnieniowych.25

Znaczenie prawidłowej diagnozy drżenia

Prawidłowa diagnoza drżenia ma kluczowe znaczenie z kilku powodów:272822

Dobór odpowiedniego leczenia

Różne typy drżenia wymagają różnych podejść terapeutycznych:2930

  • Drżenie samoistne – najczęściej leczy się propranololem (beta-bloker) lub prymidonem (lek przeciwdrgawkowy)
  • Choroba Parkinsona – wymaga leków dopaminergicznych, np. lewodopy
  • Drżenie polekowe – może wymagać odstawienia lub zmiany leku
  • Drżenie móżdżkowe – wymaga leczenia choroby podstawowej i fizjoterapii

W przypadku ciężkiego drżenia opornego na leczenie farmakologiczne, mogą być rozważane metody chirurgiczne, takie jak głęboka stymulacja mózgu (DBS) czy zabieg thalamotomii.2930

Prognozowanie przebiegu choroby

Różne typy drżenia mają różny przebieg naturalny:3113

  • Drżenie samoistne – zwykle postępuje powoli, ale może nie skracać długości życia
  • Choroba Parkinsona – ma tendencję do progresji w czasie i może skracać oczekiwaną długość życia
  • Drżenie polekowe – zwykle ustępuje po odstawieniu leku

Wykluczenie poważnych chorób podstawowych

Drżenie może być objawem poważnych chorób neurologicznych lub ogólnoustrojowych, które wymagają szybkiego rozpoznania i leczenia:2223

  • Choroba Wilsona – nieleczona może prowadzić do poważnego uszkodzenia wątroby i mózgu
  • Guzy mózgu – mogą powodować drżenie jako objaw neurologiczny
  • Udar – drżenie może być objawem udaru, wymagającego pilnej interwencji

Kiedy należy skonsultować się z lekarzem

Wystąpienie drżenia rąk nie zawsze wymaga natychmiastowej konsultacji lekarskiej, jednak istnieją sytuacje, w których należy zgłosić się do lekarza:233233

  • Gdy drżenie pojawia się nagle lub ma charakter jednostronny
  • Gdy drżenie znacząco wpływa na codzienne funkcjonowanie i jakość życia
  • Gdy drżeniu towarzyszą inne objawy neurologiczne:
    • Sztywność mięśniowa
    • Spowolnienie ruchów
    • Zaburzenia koordynacji
    • Zaburzenia mowy
    • Zaburzenia równowagi
  • Gdy drżenie postępuje lub zmienia charakter
  • Gdy drżenie występuje u młodych osób bez wyraźnej przyczyny

W przypadku nagłego wystąpienia drżenia, które rozwija się w ciągu minut do godziny, może to być objaw udaru i należy natychmiast wezwać pogotowie ratunkowe.34

Podsumowanie procesu diagnostycznego

Diagnoza drżenia rąk wymaga systematycznego podejścia i obejmuje następujące kroki:353637

  1. Dokładny wywiad medyczny:
    • Początek i progresja drżenia
    • Czynniki nasilające i łagodzące
    • Historia rodzinna
    • Przyjmowane leki
    • Schorzenia współistniejące
  2. Badanie fizykalne i neurologiczne:
    • Ocena drżenia w różnych warunkach (spoczynek, postawa, ruch)
    • Ocena siły mięśniowej, napięcia mięśniowego, koordynacji
    • Badanie odruchów
    • Ocena chodu i równowagi
  3. Badania diagnostyczne:
    • Badania laboratoryjne (hormony tarczycy, elektrolity, funkcje wątroby i nerek)
    • Badania obrazowe (MRI, CT, SPECT)
    • Badania elektrofizjologiczne (EMG, akcelerometria)
  4. Kategoryzacja typu drżenia na podstawie:
    • Warunków aktywacji (spoczynkowe, posturalne, kinetyczne)
    • Rozkładu topograficznego (które części ciała są dotknięte)
    • Częstotliwości (niska 4 Hz, średnia 4-8 Hz, wysoka >8 Hz)
  5. Diagnoza różnicowa – wykluczenie innych chorób mogących powodować drżenie

W niektórych przypadkach diagnoza może wymagać dłuższej obserwacji, ponieważ cechy drżenia mogą zmieniać się w czasie, a niektóre schorzenia, takie jak drżenie samoistne, postępują powoli.38

Warto podkreślić, że pomimo dostępności różnych badań diagnostycznych, w wielu przypadkach drżenia samoistnego nie ma specyficznego testu laboratoryjnego, który mógłby jednoznacznie potwierdzić diagnozę. Diagnoza opiera się głównie na dokładnym badaniu klinicznym i wykluczeniu innych przyczyn drżenia.3938

  • #1 Essential Tremor: What It Is, Causes, Symptoms & Treatment
    https://my.clevelandclinic.org/health/diseases/11886-essential-tremor
    Essential tremor is a movement disorder that causes uncontrollable shaking of your hands, arms and other body parts. […] Essential tremor can happen to anyone, though its more common as people age. […] Essential tremor is common. Experts estimate that it affects about 1% of all people worldwide, and about 5% of people over age 60. […] Your healthcare provider can diagnose essential tremor based on your symptoms and a neurological examination. […] However, an important part of the diagnostic process is ruling out other conditions that could cause similar symptoms. […] When your healthcare provider suspects essential tremor, they may need to rule out other conditions. […] The most common and likely tests that help rule out other conditions include blood tests, computerized tomography (CT) scan, genetic testing, magnetic resonance imaging (MRI), and positron emission tomography (PET) scan.
  • #2 Tremor | National Institute of Neurological Disorders and Stroke
    https://www.ninds.nih.gov/health-information/disorders/tremor
    Tremor is a neurological condition that includes shaking or trembling movements in one or more parts of the body, most commonly affecting a persons hands. […] Tremor can occur on its own or as a result of another disorder. […] Tremor is usually caused by a problem in the parts of the brain that control movements. […] Tremor can occur on its own or be a symptom of other neurological disorders such as Parkinsons disease, multiple sclerosis, or stroke. […] To diagnose tremor, a doctor will perform a physical exam and review the persons medical history. […] A doctor may take blood or urine samples to rule out certain contributing factors to the tremor. […] Diagnostic imaging may help determine if the tremor is the result of damage in the brain. […] An electromyogram, which measures involuntary muscle activity and muscle response to nerve stimulation, may identify muscle or nerve problems.
  • #3 Tremor: Sorting Through the Differential Diagnosis | AAFP
    https://www.aafp.org/pubs/afp/issues/2018/0201/p180.html
    A resting tremor is virtually pathognomonic for parkinsonism, whereas an intention tremor often indicates a cerebellar lesion. […] The first step is to categorize the tremor based on its activation condition, topographic distribution, and frequency. […] Patients with new-onset tremor should have a comprehensive review of medications (prescribed and over-the-counter), with specific attention to medications started before the onset of tremor. […] The assessment of tremor also includes examination for signs associated with tremor syndromes.
  • #4 Differentiation and Diagnosis of Tremor | AAFP
    https://www.aafp.org/pubs/afp/issues/2011/0315/p697.html
    If the tremor responds to a therapeutic trial of alcohol consumption (two drinks per day), the diagnosis of essential tremor is assured. […] The first step in the evaluation of a patient with tremor is to categorize the tremor based on its activation condition, topographic distribution, and frequency. […] Patients with new-onset tremor should have a comprehensive medication review with specific attention to medications (prescribed and over-the-counter) started proximal to the onset of tremor. […] The assessment of tremor also includes a careful examination for signs associated with tremor syndromes. […] The diagnosis of tremor in children is poorly understood. […] A variety of genetic conditions are associated with tremor in children, including spinal muscular atrophy, mitochondrial diseases, Huntington disease, and fragile X syndrome. […] A variety of imaging modalities have been studied to help differentiate causes of tremor. […] For particularly difficult cases, single-photon emission computed tomography (SPECT) to visualize the integrity of the dopaminergic pathways in the brain may be useful to diagnose Parkinson disease.
  • #5 Patient education: Tremor (Beyond the Basics) – UpToDate
    https://www.uptodate.com/contents/tremor-beyond-the-basics/print
    TREMOR DIAGNOSIS […] To determine what type of tremor you have and what might be causing it, your healthcare provider will need to ask you a list of detailed questions about your tremor. Your provider will probably ask: […] Does your tremor happen when you are resting, when you stand still, when you hold your arms outstretched, or when you are moving? […] Your description of the tremor and your healthcare provider’s observations of the tremor hold the most important clues about your condition. Your healthcare provider may recommend a brain scan or blood tests to pursue the diagnosis, especially if the cause of the tremor is not due to Parkinson disease or ET. […] During the examination, your healthcare provider may ask you to stand and hold your arms outstretched, or ask you to do other things that might elicit or worsen the tremor. For instance, he or she may ask you to touch your nose with one finger, or to show a sample of your handwriting. Seeing how the tremor changes under these circumstances can help determine what the cause of your tremor might be. […] Lab tests — Because tremor is sometimes caused by another medical problem, your healthcare provider may recommend tests to check for one or more of those conditions. For example, he or she may order: Blood tests to measure thyroid hormone levels or to check for copper or other metals in the blood […] Brain scans to exclude tumors, strokes, or other types of brain damage.
  • #6 Tests Used to Diagnose Tremor – Cala Health
    https://calahealth.com/tremor-resources/general-tremor/tests-used-to-diagnose-tremor/
    Internists and neurologists use a series of approaches to diagnose a patient with tremor. […] One diagnostic tool that doctors may use to test and diagnose a tremor is a drawing task known as a spiral test or an Archimedes spiral test. […] The Archimedes spiral is important because it captures the frequency, direction, and amplitude of a tremor. During this test, patients are required to draw an unbroken spiral, once with their left hand and once with their right hand. […] The resulting spiral can provide evidence for the type and severity of a tremor. This drawing task, alongside other clinical data and tests, can help inform diagnoses and treatments for tremor. […] The Archimedes test also allows the neurologist or physician to better determine the severity of the tremor. […] Essential tremor, while not life-threatening on its own, can cause serious disruptions in your life and prevent you from performing certain tasks effectivelyor sometimes at all. In order to get the essential tremor diagnosis, your physician will likely conduct a series of tests and ask you questions about what tasks you find difficult. […] Pen and paper tasks are often employed to differentiate between the types of tremors and their associated health conditions.
  • #7 Tremor: Sorting Through the Differential Diagnosis | AAFP
    https://www.aafp.org/pubs/afp/issues/2018/0201/p180.html
    Tremor is an involuntary, rhythmic, oscillatory movement of a body part. It is the most common movement disorder encountered in primary care. The diagnosis of tremor is based on clinical information obtained from the history and physical examination. The most common tremors in patients presenting to primary care physicians are enhanced physiologic tremor, essential tremor, and parkinsonian tremor. […] If there is diagnostic uncertainty, single-photon emission computed tomography can be used to visualize the integrity of the dopaminergic pathways in the brain, and transcranial ultrasonography may be useful to diagnose Parkinson disease. […] The diagnosis of essential tremor is clinical, based on classic symptoms and tremor features. […] The diagnosis of tremor is generally based on clinical information obtained from the history and physical examination.

    https://www.nyp.org/neuro/parkinsons-disease-movement-disorders/tremor/treatment
    How Are Tremors Diagnosed? […] To determine a tremor diagnosis, your physician will start with a physical exam and neurologic assessment. […] In addition to a physical and neurological exam, your doctor may order certain tests to be performed, including: […] Blood and urine samples to check for thyroid disease, infection, or other conditions. […] Electromyogram (EMG) to measure a muscles response to nerve stimulation and check involuntary muscle activity. […] The neurologists and neurosurgeons at NewYork-Presbyterian have extensive experience in diagnosing the symptoms of tremor and offering advanced treatment options.
  • #10 Essential Tremor Workup: Approach Considerations, Imaging Studies, Other Tests
    https://emedicine.medscape.com/article/1150290-workup
    Single-photon emission CT (SPECT) scanning using ioflupain 123 I (DaTSCAN) is a US Food and Drug Administration (FDA) approved procedure that can help determine whether there is loss of dopamine neurons as occurs in Parkinson’s disease and related disorders (and not in essential tremor), thus helping to distinguish these conditions. […] In 2017, researchers described an electrophysiological measure that can discriminate Parkinson’s disease tremor and essential tremor with high diagnostic accuracy. The tremor stability index, derived from kinematic measurements of tremulous activity, was tested in a cohort comprising 16 rest tremor recordings in tremor-dominant Parkinson’s disease and 20 postural tremor recordings in essential tremor, and validated on a second, independent cohort comprising a further 55 tremulous Parkinson’s disease and essential tremor recordings. The index’s maximum sensitivity, specificity and accuracy were 95%, 95% and 92%, respectively.
  • #11 Comparing Essential Tremor and Parkinson’s Disease Symptoms | Abbott Newsroom
    https://www.abbott.com/corpnewsroom/pain-and-movement/comparing-essential-tremor-and-parkinson-s-disease-symptoms.html
    When someone has trembling hands or involuntary movements in their arms, legs or head, people tend to conclude the shaking is a sign of Parkinson’s disease. […] However, the symptoms may be the result of a more common, less severe condition called essential tremor. Essential tremor can be confused with typical Parkinson’s disease symptoms, but the two movement disorders are separate conditions. […] Essential tremor is the most common type of tremor. It’s a neurological disorder that causes involuntary shaking, most often of the hands and arms. The condition is not life-threatening, though in severe cases it can cause disability. […] Tremors start in the hands and arms and can affect the head and voice as well. […] Doctors and researchers aren’t sure what causes essential tremor, but it may be inherited.
  • #12 Causes of Tremor Other than Parkinson’s | APDA
    https://www.apdaparkinson.org/article/other-causes-of-tremor/
    Many people think of Parkinsons disease (PD) as the tremor disease, so much so, that when a tremor is noticed, the first diagnosis people typically think of is PD. […] However, there are many other medical conditions that can cause a tremor. […] When deciding whether a tremor is consistent with a diagnosis of PD, the most important feature is the position of the body part in which the tremor occurs. […] Parkinsons tremors classically occur at two characteristic times. One is at rest. The other is when the limb is moved and then held against gravity. […] Therefore, if you have a tremor, it is best to get checked out by a neurologist. […] A PD tremor typically has a frequency of about 3-6 Hz, which means that the body part moves back and forth about 3-6 times a second. […] A PD tremor most commonly affects the fingers or hand, but can also affect the legs and jaw.
  • #13 Comparing Essential Tremor and Parkinson’s Disease Symptoms | Abbott Newsroom
    https://www.abbott.com/corpnewsroom/pain-and-movement/comparing-essential-tremor-and-parkinson-s-disease-symptoms.html
    Essential tremor doesn’t cause associated health problems, while Parkinson’s carries other symptoms, such as stooped posture and balance problems. […] Essential tremor may affect the voice box, but Parkinson’s does not. […] Essential tremors are usually felt more when in motion, but Parkinson’s tremors are felt more when at rest. […] Essential tremor symptoms can progressively get worse, but won’t necessarily shorten the patient’s life span. Parkinson’s tends to progress over time and may shorten the patient’s life span as the brain produces less and less levodopa over time. […] For many people, essential tremor may be mild and may not interfere with daily life. However, any tremor that worsens should be evaluated by a doctor. […] Medications, physical therapy, deep brain stimulation and other techniques may be used to manage tremors, depending on how severe they are.
  • #14 Essential tremors vs. Parkinson’s — how to tell why your hands shake and when to see a doctor for tremors | Louisville, Ky.Norton Healthcare

    Shaky hands don’t always mean you have Parkinson’s. You might associate uncontrollable shaking of the body with Parkinson’s disease. Although shaking is a classic sign of Parkinson’s, there are other movement disorders that include similar symptoms. Essential tremor affects about 10 million Americans, and Parkinson’s affects about 1 million. Telling these two conditions apart can be tricky, and diagnosis can take time. […] Signs of essential tremor include: Shaking on both sides of the body, Shaking that usually happens during activity, such as writing or eating, Tremors without other symptoms, Symptoms that vary in age of onset, intensity, duration, progression and resulting disability, Shaking mainly in the hands, but can include head and voice tremor. […] There are several key ways essential tremor is different from Parkinson’s disease.

    https://nortonhealthcare.com/news/essential-tremor-vs-parkinson/
    Signs of Parkinson’s disease include: Shaking mainly on one side of the body, Shaking that happens when the body is at rest, Slowness of movement (bradykinesia), Muscle rigidity and stiffness, Average age of onset 60 years old; typically with increased disability over time, Shaking occurring in the upper and lower extremities; usually not in the head. […] Early signs of Parkinson’s and essential tremor can overlap. A patient can have both conditions, so it’s important to understand the differences in these disorders. People sometimes assume that if they shake at all, it’s Parkinson’s. That isn’t the case. […] If you have any of the symptoms associated with Parkinson’s disease or tremor, talk to your health care provider—not only to diagnose your condition but also to rule out other causes for your symptoms.

    In some cases, this may mean that you need to have some tests to rule out other conditions. […] The appearance of your tremor, in the setting of a comprehensive neurological examination by an experienced clinician, can result in diagnosis of essential tremor. […] What tests may be done to diagnose essential tremor? When your healthcare provider suspects essential tremor, they may need to rule out other conditions. […] If your doctor is still unsure if your tremor is essential tremor or Parkinson’s disease, he or she might order a dopamine transporter scan.

    https://practicalneurology.com/articles/2018-may/evaluation-of-patients-with-tremor
    The typical parkinsonian tremor of Parkinsons disease (PD) is always unilateral in onset, affecting the hand (or occasionally the leg) at rest. […] The resting tremor of PD typically disappears if the hand is repositioned, only to return 10 to 15 seconds later if the new resting posture is maintained. […] Enhanced physiologic tremor is another common reason for referral to the office. […] Cerebellar tremor may accompany disorders that affect the cerebellar neurons (eg, spinocerebellar ataxias, olivopontocerebellar degeneration) or the afferent or efferent connections of the cerebellum (eg, multiple sclerosis, brainstem strokes). […] Functional, or psychogenic, tremor may mimic organic tremor syndromes. […] Drug-induced tremors are also not uncommon and may cause rest or action tremor dependent on the drug.

    Perhaps most important of all in deciding whether a tremor is consistent with PD or another disorder is determining whether other symptoms of PD are present, in addition to the tremor. […] There are numerous other medical conditions that can cause postural or kinetic tremor, and these are considered during evaluation of a tremor: […] Essential tremor (ET) is very common, affecting about 4 percent of the population in those aged 65 and older. […] A wide variety of medications can cause tremor. […] Certain metabolic disturbances such as hyperthyroidism (or excessive production of thyroid hormone) can lead to a tremor. […] Dystonic tremor occurs as part of dystonia, a movement disorder in which repetitive and sustained muscle contractions result in twisting movements of a body part.

    Tremor can be a sign of a neuropathy, a disorder of the peripheral nerves, or the nerves that bring messages from the brain and spinal cord to rest of the body. […] Orthostatic tremor is a relatively uncommon tremor of the legs which occurs primarily when a person is standing but not when sitting or walking. […] A rubral tremor is a relatively slow tremor which is present both at rest and action. […] A cerebellar tremor manifests as a specific type of kinetic tremor known as an intention tremor, one that worsens when trying to accurately reach a target. […] Atypical parkinsonian syndromes such as Multiple System Atrophy (MSA) can have tremor as one of its symptoms. […] There are many causes of tremor besides PD so you should not automatically think anyone with a tremor must have PD.

    Dystonic tremor is a somewhat controversial entity, in which patients with dystonia may also have tremor in the same part of the body affected by dystonia. […] Holmes tremor is rare and typically occurs in a delayed fashion after a structural lesion has affected the cerebellar thalamus, dentate nucleus, or middle cerebellar peduncle. […] Orthostatic tremor is an unusual tremor that affects the trunk and legs and is specifically triggered by standing. […] Some patients with tremor presenting to the office have tremors that are unusual or difficult to classify.

    The first step in the evaluation of a patient presenting with shaking is to determine whether the abnormal movements are really tremor, because various movements can be erroneously described as shaking or tremor. […] A rhythmic character of the movement is the key feature that differentiates tremor from other mimics. […] The next step is to describe the tremor in a way that gives a clear picture of its characteristics. […] A thorough description of the tremor allows for phenomenologic classification. […] By this point, we should be able to classify the tremor into one of the subgroups mentioned in Box 1. More than one type of tremor can exist in a patient, and it is useful to determine the predominant type of tremor. […] Phenomenologic classification facilitates clarification of the cause, with the help of clues provided by history, examination and, in some patients, investigations.

    Essential tremor is a condition that may slowly progress over time, and a conclusive diagnosis of essential tremor can take time. […] Diagnosing essential tremor can be somewhat difficult. Part of the reason why is because there is no definitive test available that will indicate whether or not what you’re experiencing is essential tremor. […] During the diagnostic process for essential tremor, your doctor should generally take the following factors into account: […] A tremor must persist for some time in order to make an essential tremor diagnosis. […] While there isn’t any test that can provide you with a definitive diagnosis of essential tremor, there are some tests that your doctor can use as diagnostic tools. […] To reach a diagnosis of essential tremor, your doctor will ask you questions, give you a physical exam, and possibly administer one or more of the tests described in the previous section. Since there’s still no specific test that can provide a definitive diagnosis of essential tremor, the diagnostic process is essentially a process of elimination.
  • #39 Essential tremor – Wikipedia
    https://en.wikipedia.org/wiki/Essential_tremor
    Usually, the diagnosis is established on clinical grounds. […] Diagnosis is made by observing the typical pattern of the tremor coupled with the exclusion of known causes of such a tremor. There is currently no medical test available to identify an essential tremor. […] According to recent medical literature, besides isolated essential tremor, there are two additional classifications: 'ET plus’ and 'ET-PD.’ 'ET plus’ is diagnosed when patients show cognitive impairments or other motor symptoms like ataxia, dystonia, or resting tremor. 'ET-PD’ is used for those who meet the criteria for both ET and Parkinson’s disease. […] For some types of tremors, additional tests like recording tremor frequency, imaging for lesions, receptor imaging, and biomarkers in blood or tissue may help identify the cause.
