Demencja ciałek lewy’ego
Objawy

Demencja ciałek Lewy’ego (DCL) jest drugą co do częstości przyczyną demencji po chorobie Alzheimera, charakteryzującą się postępującym pogorszeniem funkcji poznawczych, zaburzeniami ruchowymi, fluktuacjami poznawczymi oraz halucynacjami wzrokowymi, które występują u około 80% pacjentów. Choroba dotyka głównie osoby powyżej 50. roku życia, z nieco wyższą częstością u mężczyzn. Typowe objawy obejmują zaburzenia poznawcze (spadek zdolności myślenia, planowania, rozumowania), objawy parkinsonowskie (spowolnienie ruchów, sztywność, drżenie), zaburzenia snu REM oraz dysautonomię (ortostatyczne spadki ciśnienia, zaparcia, nietrzymanie moczu). Przebieg choroby trwa średnio 5-8 lat, z indywidualnymi wahaniami od 2 do 20 lat, i dzieli się na stadia od wczesnego, przez środkowe, do późnego, z progresją objawów poznawczych, motorycznych i autonomicznych. Charakterystyczne dla DCL są fluktuacje poznawcze, wczesne halucynacje wzrokowe oraz nadwrażliwość na neuroleptyki, co odróżnia ją od choroby Alzheimera i otępienia w chorobie Parkinsona.

Demencja ciałek Lewy’ego – Objawy

Demencja ciałek Lewy’ego (DCL) jest jednym z najczęstszych rodzajów demencji po chorobie Alzheimera. Charakteryzuje się postępującym pogorszeniem zdolności umysłowych, które z czasem staje się coraz bardziej nasilone. DCL powoduje zmiany w myśleniu, zachowaniu, nastroju, ruchu i autonomicznym układzie nerwowym.12

Choroba ta jest wynikiem gromadzenia się nieprawidłowych złogów białkowych, znanych jako ciałka Lewy’ego, w mózgu. Złogi te zaburzają normalne funkcjonowanie mózgu, prowadząc do jego stopniowego uszkodzenia i pogorszenia zdolności poznawczych. Demencja ciałek Lewy’ego najczęściej dotyka osoby po 50. roku życia, a choroba ta występuje nieco częściej u mężczyzn niż u kobiet.34

Główne objawy demencji ciałek Lewy’ego

Choroba może prezentować się różnymi objawami, a ich nasilenie może się znacznie różnić u poszczególnych pacjentów. Do najczęstszych objawów zaliczamy:

  • Zaburzenia poznawcze – postępujący spadek zdolności myślenia, planowania, rozumowania i rozwiązywania problemów5
  • Halucynacje wzrokowe – widzenie rzeczy, których nie ma, występujące u około 80% osób z DCL, często są to realistyczne i szczegółowe obrazy ludzi, zwierząt lub przedmiotów16
  • Fluktuacje poznawcze – nieprzewidywalne zmiany w koncentracji, uwadze i czujności, które mogą występować z dnia na dzień, a nawet w ciągu jednego dnia57
  • Objawy parkinsonowskie – spowolnienie ruchów, sztywność mięśni, drżenie, zaburzenia równowagi, pochylona postawa, trudności z chodzeniem89
  • Zaburzenia snu REM – zachowania związane z szybkim ruchem gałek ocznych podczas snu, prowadzące do fizycznego odgrywania snów, często gwałtownego102

Warto podkreślić, że zaburzenia snu REM mogą wystąpić na wiele lat przed pojawieniem się innych objawów DCL, stanowiąc wczesny sygnał ostrzegawczy.11

Zaburzenia autonomicznego układu nerwowego

Demencja ciałek Lewy’ego może wpływać na autonomiczny układ nerwowy, który kontroluje nieświadome funkcje organizmu, takie jak ciśnienie krwi, tętno, pocenie się i trawienie. Objawy dysautonomii mogą obejmować:112

  • Zaburzenia regulacji ciśnienia krwi, w tym ortostatyczne spadki ciśnienia
  • Zaburzenia termoregulacji
  • Zaparcia
  • Nietrzymanie moczu
  • Dysfunkcje seksualne
  • Zmniejszenie percepcji zapachu
  • Nadmierne ślinienie się

Te problemy autonomiczne mogą znacząco wpływać na jakość życia pacjentów i zwiększać ryzyko upadków oraz innych powikłań.13

Zaburzenia nastroju i zachowania

Osoby z demencją ciałek Lewy’ego często doświadczają zmian nastroju i zachowania, które mogą obejmować:914

  • Depresję – utrzymujące się uczucie smutku, brak zainteresowania codziennymi aktywnościami
  • Apatię – brak motywacji i inicjatywy, obojętność wobec wydarzeń
  • Lęk – intensywne uczucie niepokoju, niepewności lub strachu
  • Pobudzenie – niepokój ruchowy, drażliwość
  • Urojenia – silnie podtrzymywane fałszywe przekonania, w tym zespół Capgrasa (przekonanie, że bliski został zastąpiony przez oszusta)
  • Paranoję – irracjonalna nieufność wobec innych

Zmiany w zachowaniu mogą być szczególnie trudne dla opiekunów i mogą nasilać się wraz z postępem choroby.15

Progresja demencji ciałek Lewy’ego

Demencja ciałek Lewy’ego jest chorobą postępującą, co oznacza, że objawy zaczynają się powoli i nasilają z upływem czasu. Choroba trwa średnio od 5 do 8 lat od momentu diagnozy do śmierci, ale może wahać się od 2 do 20 lat. Szybkość rozwoju i zmiany objawów różnią się znacznie u poszczególnych osób, w zależności od ogólnego stanu zdrowia, wieku i nasilenia objawów.166

Etapy progresji choroby

Przebieg demencji ciałek Lewy’ego można ogólnie podzielić na trzy główne etapy: wczesny, środkowy i późny, choć czasami wyróżnia się bardziej szczegółowy podział na siedem stadiów. Należy pamiętać, że progresja demencji ciałek Lewy’ego nie zawsze przebiega liniowo i może charakteryzować się okresami względnej stabilizacji przeplatanymi nagłymi pogorszeniami.1718

Wczesne stadium

We wczesnym stadium DCL objawy mogą być łagodne i mieć mniejszy wpływ na codzienne funkcjonowanie. Na tym etapie można zaobserwować:1619

  • Halucynacje wzrokowe – występujące u aż 80% osób z DCL we wczesnym stadium choroby
  • Łagodne zaburzenia poznawcze – problemy z wielozadaniowością, funkcjami wykonawczymi i uwagą, choć pamięć może być względnie zachowana
  • Łagodne objawy parkinsonowskie – subtelne zmiany w piśmie odręcznym, lekkie drżenie, nieznaczna sztywność
  • Zaburzenia snu REM – fizyczne odgrywanie snów podczas snu
  • Epizody dezorientacji – krótkotrwałe okresy splątania lub zaburzeń świadomości

Na tym etapie pacjenci mogą nadal funkcjonować stosunkowo samodzielnie, choć mogą potrzebować wsparcia przy bardziej złożonych zadaniach.7

Stadium środkowe

W miarę postępu choroby objawy stają się bardziej wyraźne i zaczynają znacząco wpływać na codzienne życie:1917

  • Narastające problemy poznawcze – znaczące okresy dezorientacji, trudności z rozpoznawaniem miejsc i osób, problemy z pamięcią
  • Fluktuacje poznawcze – wyraźne wahania poziomu uwagi i świadomości
  • Nasilone halucynacje i urojenia – mogą stać się bardziej intensywne i niepokojące
  • Postępujące objawy parkinsonowskie – znaczące trudności z poruszaniem się, częste upadki
  • Problemy z mową – spowolnienie mowy, trudności w znajdowaniu słów
  • Zaburzenia nastroju – depresja, lęk, apatia, drażliwość
  • Problemy z autonomicznym układem nerwowym – nietrzymanie moczu, zaparcia, zawroty głowy przy zmianie pozycji

W tym stadium pacjenci zazwyczaj wymagają regularnej pomocy w codziennych czynnościach i nadzoru dla zapewnienia bezpieczeństwa.20

Stadium późne

W późnym stadium demencji ciałek Lewy’ego pacjenci doświadczają znacznego pogorszenia funkcji poznawczych i fizycznych:192120

  • Głębokie zaburzenia poznawcze – znacząca utrata pamięci, trudności w rozpoznawaniu bliskich osób
  • Poważne problemy z komunikacją – ograniczona zdolność mówienia lub jej całkowita utrata
  • Zaawansowane zaburzenia motoryczne – znaczące trudności z poruszaniem się lub całkowite unieruchomienie
  • Problemy z połykaniem – ryzyko zachłyśnięcia i aspiracji pokarmu do płuc
  • Nietrzymanie moczu i stolca
  • Zredukowana ekspresja twarzy
  • Całkowita zależność od opiekunów we wszystkich aspektach codziennego życia

W tym stadium pacjenci wymagają całodobowej opieki, a głównym celem jest zapewnienie komfortu i godności.2022

Siedem stadiów demencji ciałek Lewy’ego

Niektórzy specjaliści opisują progresję DCL w bardziej szczegółowy sposób, wyróżniając siedem stadiów:231824

  1. Stadium 1: Brak pogorszenia poznawczego – brak objawów, chociaż u niektórych pacjentów mogą wystąpić zaburzenia snu, halucynacje lub wahania nastroju
  2. Stadium 2: Bardzo łagodne pogorszenie poznawcze – drobne problemy z pamięcią, trudności z przypominaniem sobie nazw lub lokalizacją znajomych przedmiotów
  3. Stadium 3: Łagodne pogorszenie poznawcze – łagodne problemy z pamięcią, koncentracją, zwiększone ryzyko upadków, trudności z kontynuowaniem codziennych aktywności
  4. Stadium 4: Umiarkowane pogorszenie poznawcze – na tym etapie zazwyczaj następuje diagnoza, występują problemy z połykaniem, aspiracją, nadmiernym ślinieniem się, drżeniem i mową, zaburzenia pamięci, trudności z wykonywaniem codziennych obowiązków
  5. Stadium 5: Umiarkowanie ciężkie pogorszenie poznawcze – znaczna utrata pamięci, trudności z codziennymi czynnościami, znaczne splątanie, dezorientacja, niemożność samodzielnego życia, urojenia i halucynacje
  6. Stadium 6: Ciężkie pogorszenie poznawcze – nietrzymanie moczu i stolca, utrata zdolności mówienia, trudności z rozpoznawaniem członków rodziny, zmiany osobowości
  7. Stadium 7: Bardzo ciężkie pogorszenie poznawcze – ograniczona komunikacja, niemożność chodzenia, konieczność całodobowej opieki, całkowita utrata kontroli nad czynnościami fizjologicznymi

Należy podkreślić, że nie każda osoba z DCL doświadczy wszystkich objawów lub przejdzie przez wszystkie stadia w jednakowy sposób. Progresja choroby jest bardzo indywidualna.1825

Charakterystyczne cechy progresji demencji ciałek Lewy’ego

Kilka cech wyróżnia progresję DCL od innych typów demencji:71926

  • Fluktuacje poznawcze – jedną z najbardziej charakterystycznych cech DCL jest występowanie fluktuacji poznawczych, gdzie pacjent może mieć „dobre” i „złe” dni pod względem funkcji poznawczych, a nawet doświadczać wahań w ciągu jednego dnia
  • Wczesne halucynacje wzrokowe – w przeciwieństwie do choroby Alzheimera, halucynacje wzrokowe często pojawiają się wcześnie w przebiegu DCL
  • Zmienne nasilenie objawów parkinsonowskich – objawy ruchowe mogą się zmieniać w czasie i nie zawsze korelują z nasileniem objawów poznawczych
  • Nadwrażliwość na leki neuroleptyczne – osoby z DCL często wykazują zwiększoną wrażliwość na leki przeciwpsychotyczne, które mogą powodować znaczne pogorszenie funkcji poznawczych i motorycznych
  • Zaburzenia snu REM – te zaburzenia mogą wyprzedzać inne objawy demencji o wiele lat

Te cechy mogą pomóc w odróżnieniu DCL od innych typów demencji, takich jak choroba Alzheimera czy demencja naczyniowa.2127

Różnice między demencją ciałek Lewy’ego a innymi typami demencji

Demencja ciałek Lewy’ego często bywa mylona z innymi typami demencji, szczególnie z chorobą Alzheimera i otępieniem w chorobie Parkinsona. Istnieją jednak pewne kluczowe różnice, które pomagają w rozpoznaniu DCL:2619

Demencja ciałek Lewy’ego vs choroba Alzheimera

Chociaż zarówno DCL, jak i choroba Alzheimera powodują problemy z uwagą, podejmowaniem decyzji, pamięcią i postrzeganiem otoczenia, istnieją znaczące różnice:2128

  • Problemy z pamięcią – w DCL problemy z pamięcią mogą nie być tak wyraźne we wczesnych stadiach choroby jak w chorobie Alzheimera
  • Halucynacje – w DCL halucynacje wzrokowe często pojawiają się wcześnie, podczas gdy w chorobie Alzheimera zazwyczaj występują w późniejszych stadiach
  • Fluktuacje poznawcze – znaczne wahania uwagi i czujności są bardziej charakterystyczne dla DCL
  • Objawy parkinsonowskie – sztywność, spowolnienie ruchowe i problemy z równowagą są powszechne w DCL, ale rzadkie we wczesnych stadiach choroby Alzheimera
  • Zaburzenia snu REM – występują często w DCL, ale rzadko w chorobie Alzheimera

Demencja ciałek Lewy’ego vs otępienie w chorobie Parkinsona

DCL i otępienie w chorobie Parkinsona (PDD) są blisko spokrewnionymi zaburzeniami, które różnią się głównie kolejnością pojawienia się objawów:2911

  • Chronologia objawów – w DCL objawy poznawcze i parkinsonowskie pojawiają się prawie jednocześnie lub objawy poznawcze wyprzedzają objawy ruchowe o mniej niż rok; w PDD demencja rozwija się co najmniej rok po wystąpieniu objawów parkinsonowskich
  • Tempo progresji – DCL zazwyczaj postępuje szybciej niż PDD
  • Lokalizacja ciałek Lewy’ego – w DCL ciałka Lewy’ego są bardziej rozproszone w mózgu, podczas gdy w PDD początkowo koncentrują się głównie w pniu mózgu i jądrach podstawy

Warto zauważyć, że niezależnie od początkowych różnic, wraz z postępem obu chorób, objawy stają się bardzo podobne.2630

Wpływ progresji demencji ciałek Lewy’ego na życie pacjenta

Progresja demencji ciałek Lewy’ego ma głęboki wpływ na życie pacjenta i jego opiekunów. W miarę postępu choroby, zdolność do samodzielnego funkcjonowania stopniowo się zmniejsza, a zapotrzebowanie na opiekę zwiększa.631

Wpływ na codzienne funkcjonowanie

Wraz z postępem choroby, zdolność pacjenta do wykonywania codziennych czynności stopniowo się pogarsza:3116

  • We wczesnym stadium – pacjenci mogą nadal prowadzić stosunkowo niezależne życie, choć mogą mieć trudności z bardziej złożonymi zadaniami, takimi jak zarządzanie finansami czy planowanie
  • W stadium środkowym – pacjenci zazwyczaj wymagają regularnej pomocy przy codziennych czynnościach, takich jak przygotowywanie posiłków, kąpiel, ubieranie się
  • W stadium późnym – pacjenci stają się całkowicie zależni od opiekunów we wszystkich aspektach życia, w tym odżywianiu, higienie osobistej i mobilności

Ta stopniowa utrata niezależności może być przygnębiająca zarówno dla pacjentów, jak i ich opiekunów.6

Wpływ na relacje społeczne i rodzinne

Demencja ciałek Lewy’ego wpływa również na relacje społeczne i rodzinne pacjenta:3233

  • Zmiany w komunikacji – trudności w komunikacji mogą prowadzić do frustracji i izolacji
  • Zmiany osobowości – zmiany zachowania, drażliwość i apatia mogą wpływać na dotychczasowe relacje
  • Obciążenie opiekunów – w miarę postępu choroby, obciążenie opiekunów znacząco wzrasta, co może prowadzić do napięć rodzinnych
  • Nieprzewidywalność objawów – fluktuacje poznawcze i wahania nastroju mogą być trudne do zrozumienia dla osób z otoczenia pacjenta

Wsparcie społeczne i edukacja rodziny mogą pomóc w radzeniu sobie z tymi wyzwaniami.34

Zagrożenia zdrowotne związane z progresją choroby

W miarę postępu demencji ciałek Lewy’ego, pacjenci narażeni są na zwiększone ryzyko różnych powikłań zdrowotnych:3521

  • Upadki i urazy – problemy z równowagą i koordynacją zwiększają ryzyko upadków
  • Problemy z odżywianiem – trudności z połykaniem mogą prowadzić do niedożywienia i odwodnienia
  • Infekcje – osłabienie ogólne i unieruchomienie zwiększają podatność na infekcje, szczególnie układu oddechowego i moczowego
  • Zachłystowe zapalenie płuc – trudności z połykaniem zwiększają ryzyko aspiracji pokarmu do płuc
  • Odleżyny – u pacjentów unieruchomionych
  • Powikłania związane z lekami – nadwrażliwość na leki, szczególnie neuroleptyki, może prowadzić do poważnych działań niepożądanych

Proaktywne zarządzanie tymi ryzykami jest kluczowym elementem opieki nad pacjentem z DCL.36

Demencja ciałek Lewy’ego – postępowanie

Chociaż nie ma obecnie leku na demencję ciałek Lewy’ego, istnieją różne strategie leczenia i wsparcia, które mogą poprawić jakość życia pacjentów i ich opiekunów:3738

Farmakoterapia

Leczenie farmakologiczne może pomóc w łagodzeniu niektórych objawów DCL:323739

  • Inhibitory cholinesterazy (np. rywastygmina) – mogą poprawić funkcje poznawcze i zmniejszyć halucynacje
  • Leki przeciwparkinsonowskie (np. lewodopa) – mogą łagodzić objawy parkinsonowskie, chociaż mogą nasilać halucynacje
  • Pimawanseryna – może zmniejszać halucynacje
  • Leki przeciwpsychotyczne – stosowane ostrożnie ze względu na zwiększoną wrażliwość pacjentów z DCL, preferowane są nowsze leki z większym wpływem na receptory serotoninowe (np. kwetiapina, klozapina)
  • Melatonina i klonazepam – mogą być pomocne w zaburzeniach snu REM

Należy podkreślić, że stosowanie leków u pacjentów z DCL wymaga szczególnej ostrożności ze względu na ich zwiększoną wrażliwość na działania niepożądane.3632

Terapie niefarmakologiczne

Podejście niefarmakologiczne odgrywa ważną rolę w opiece nad pacjentami z DCL:640

  • Fizjoterapia – może pomóc w utrzymaniu mobilności i równowagi, zmniejszając ryzyko upadków
  • Terapia zajęciowa – pomaga w dostosowaniu środowiska i rozwijaniu strategii radzenia sobie z codziennymi czynnościami
  • Terapia mowy – wspiera umiejętności komunikacyjne i pomaga w problemach z połykaniem
  • Stymulacja poznawcza – ćwiczenia umysłowe odpowiednie do możliwości pacjenta
  • Terapie uzupełniające – muzykoterapia, arteterapia, terapia z udziałem zwierząt

Te podejścia mogą poprawić funkcjonowanie pacjenta i jego dobrostan psychiczny.41

Wsparcie dla opiekunów

Opieka nad osobą z demencją ciałek Lewy’ego może być fizycznie i emocjonalnie wyczerpująca. Wsparcie dla opiekunów jest kluczowym elementem kompleksowej opieki:3234

  • Edukacja – zrozumienie choroby i jej przebiegu pomaga opiekunom lepiej przygotować się na wyzwania
  • Grupy wsparcia – umożliwiają wymianę doświadczeń i strategii radzenia sobie
  • Opieka wytchnieniowa – zapewnia opiekunom niezbędny odpoczynek
  • Poradnictwo psychologiczne – pomaga w radzeniu sobie ze stresem i żałobą antycypacyjną
  • Pomoc praktyczna – wsparcie w codziennych czynnościach i opiece nad pacjentem

Dobrostan opiekunów ma bezpośredni wpływ na jakość opieki nad pacjentem, dlatego wsparcie dla nich jest nieodłącznym elementem kompleksowego podejścia do leczenia DCL.34

Demencja ciałek Lewy’ego stanowi znaczące wyzwanie zarówno dla pacjentów, jak i ich opiekunów. Zrozumienie progresji choroby i dostępnych opcji wsparcia może pomóc w lepszym przygotowaniu się na wyzwania związane z tą chorobą i poprawić jakość życia wszystkich zaangażowanych osób.642

    Dementia with Lewy bodies (DLB) is a type of progressive dementia that leads to a decline in thinking, reasoning and independent function. Its features may include spontaneous changes in attention and alertness, recurrent visual hallucinations, REM sleep behavior disorder, and slow movement, tremors or rigidity. […] Core symptoms of dementia with Lewy bodies include: Changes in thinking and reasoning. Fluctuating cognition that is delirium-like. Recurrent well-formed visual hallucinations. REM sleep behavior disorder that involves acting out dreams. Spontaneous parkinsonism with slowness of movement, rest tremor, or rigidity. […] Other symptoms may include: Trouble interpreting visual information. Malfunctions of the „automatic” (autonomic) nervous system, which controls automatic functions of the body, such as sweating, blood pressure, heart rate, digestion and sexual response.

    Lewy body dementia (LBD) is one of the most common types of dementia, after Alzheimers disease. It usually affects people aged 50 or older. […] Not everyone will have the same warning signs. They often depend on the type of LBD you have. They might be mild or get worse at times. […] Like other types of dementia, LBD causes changes in your thinking, mood, behavior, movement, and sleep. Symptoms include: […] Hallucinations are often the first sign of LBD. They affect about 80% of people with the disease. […] Some other early symptoms include: […] LBD can affect a part of your nervous system that regulates the way your heart, glands, and muscles work. This can cause: […] The average life expectancy for someone with LBD is around 7-8 years after symptoms begin. But, a persons outlook can vary quite a bit. Some people with LBD live up to 20 years after a diagnosis. […] LBD is a form of dementia that leads to problems with your thinking, mood, movement, behavior, and sleep. Though LBD gets worse over time, you can still live a rewarding life.

    https://www.barrowneuro.org/condition/lewy-body-disease/
    Lewy body dementia is a related condition to Parkinson’s disease. These conditions involve the accumulation of an abnormal protein in brain cells. These deposits are called “Lewy bodies.” […] In Lewy body dementia, the physical symptoms of Parkinson’s disease begin around the same time as the cognitive symptoms. There is also a tendency for the confusion to wax and wane (“good days and bad days”) and for the person to experience visual hallucinations. […] Symptoms of Lewy body dementia include: Slow thinking, Memory loss, Difficulty with learning and abstract thinking, Fluctuating severity of symptoms, Visual hallucinations, Sensitivity to some medications, Physical symptoms of Parkinson’s disease. […] Lewy body dementia usually begins between the ages of 50 and 85. It affects men slightly more than women. People who have a parent or sibling with Lewy body disease might have a greater risk than someone without a family history. […] Doctors usually diagnose Lewy body dementia by the combination of physical signs and symptoms of Parkinson’s disease and the mental symptoms of Lewy body dementia. Imaging studies such as PET and SPECT scans are sometimes done. Sleep studies may assist in the diagnosis.

    The most common symptoms of LBD include changes in cognition, movement, sleep, behavior, and body functions that happen without you thinking about them (autonomic functions), such as dizziness on standing (caused by low blood pressure) and constipation. […] LBD causes changes in thinking abilities. These changes may include: Dementia: Loss of thinking abilities that interferes with a persons capacity to perform daily activities. Dementia is a primary symptom of LBD and usually includes trouble with attention, visual and special abilities (judging distance and depth or misidentifying objects), reasoning, and executive memory functioning (multitasking and problem solving). […] Cognitive fluctuations: Unpredictable changes in concentration, attention, alertness, and wakefulness from day to day and sometimes throughout the day.

    Lewy body dementia (LBD) is a brain disorder that can lead to problems with thinking, movement, behavior, and mood. Visual hallucinations, or seeing things that are not there, are a common symptom, and tend to happen early on. […] It is a progressive disease, meaning symptoms start slowly and worsen over time. […] People with LBD live on average five to eight years but may live as few as two years or as long as 20 years from the time of diagnosis to death. How fast symptoms develop and change varies depending on the persons overall health, age, and level of symptoms. […] The most common symptoms of LBD include changes in thinking abilities, movement, sleep, and behavior. The degree of symptoms can vary widely and people with LBD may not have every symptom. Common symptoms include: […] Visual hallucinations, which occur in up to 80% of people with LBD, often early on.
  • #6 What Is Lewy Body Dementia?
    https://www.alzheimers.gov/alzheimers-dementias/lewy-body-dementia
    Individuals with mild symptoms can often function close to normally. As the disease progresses and thinking and movement abilities decline, people with LBD will need more help and may depend on caregivers full time. […] Although LBD currently cannot be prevented or cured, treatments may be able to help with some of the symptoms. A treatment plan may involve medications, physical and other types of therapy, and counseling. Changes to make the home safer, equipment to make everyday tasks easier, and social support are also important.
  • #7 Lewy Body Dementia (LBD) Stages: What Sets Them Apart?
    https://www.healthline.com/health/dementia/lewy-body-dementia-stages
    In LBD, sleep disorders are common. Rapid eye movement (REM) sleep behavior disorder is a feature that sets LBD apart from other dementias. […] In late stage dementia, a state of dependency has been reached. You may need full or partial assistance during daily life because symptoms impair your physical and mental function. […] In LBD, behavioral symptoms become worse as the condition progresses. […] One of the most defining characteristics of LBD is the presence of fluctuating cognition. […] LBD is often more aggressive than other types of dementia. On average, the time between diagnosis and end of life is 5 to 8 years. […] As in all dementia, late stage LBD involves significant loss of independent function, behavioral changes, and major memory deficits. […] Theres no cure for this condition, but even during its late stage, cognitive symptoms may abruptly go into remission due to whats known as fluctuating cognition.
  • #7 Lewy Body Dementia (LBD) Stages: What Sets Them Apart?
    https://www.healthline.com/health/dementia/lewy-body-dementia-stages
    Lewy body dementia (LBD) stages are similar to those seen in other dementias, but this condition is known to have unique progression patterns that can make disease predictability challenging. […] While its similar to other dementias, such as Alzheimers disease, LBD can feature a more aggressive cognitive decline and fluctuating symptoms that set it apart. […] Early stage LBD might not be obvious. It can mimic natural age-related cognitive changes. Unlike other dementias, early stage LBD is associated with greater cognitive challenges related to multitasking, as opposed to memory decline. […] Visual hallucinations can also be a common early stage symptom in LBD. […] Early stage changes to your motor function, such as tremors, rigidity, or difficulty walking, are also seen in LBD. […] The middle stage of dementia is defined by clear symptoms that can no longer be attributed to age, stress, or other circumstances.

    For people with either a DLB or PDD diagnosis, the average life expectancy from diagnosis is estimated to be 38 years. Known factors which accelerate the disease course in LBD include comorbid Alzheimers disease pathology, the presence of hallucinations and fluctuating cognition, gait abnormalities, decreased brain volume, and orthostatic hypotension. The risk of adverse events in LBD is much higher than Alzheimers disease dementia as previously outlined and in addition up to 25% of those with LBD are likely to experience at least one episode of delirium, an acute cognitive and psychiatric disturbance that can worsen dementia if left untreated. […] Degeneration in key regions of the brain leads to a cluster of cognitive, psychiatric, motor and autonomic symptoms in LBD. Generally, for those who have PDD, Lewy bodies are first predominantly found in the brainstem and basal ganglia in the mid brain which control movement and autonomic processes, producing the symptoms consistent with Parkinsons disease. The spread of Lewy bodies and death of neurons connecting to, or situated within, higher cortical regions involved in cognition is often a sign of disease progression and the onset of dementia. For DLB, Lewy bodies are often diffusely spread throughout the brain which in part explains the close onset of cognitive and motor symptoms, and predicts a more aggressive disease course.
