Zaburzenie somatyczne
Patofizjologia i mechanizm

Zaburzenie somatyczne (SSD) charakteryzuje się nadmierną świadomością doznań cielesnych i ich interpretacją jako objawów choroby somatycznej. Patogeneza jest wieloczynnikowa, obejmując zmiany w autonomicznym układzie nerwowym (np. tachykardia, wzmożona motoryka żołądka, napięcie mięśniowe), zmiany strukturalne i funkcjonalne mózgu (m.in. zmniejszona objętość ciała migdałowatego, zmieniona łączność z obszarami wykonawczymi i motorycznymi), a także procesy prozapalne. Genetyczny wkład w objawy somatyczne wynosi 7-21%, z udziałem polimorfizmów pojedynczego nukleotydu, szczególnie w układzie monoaminergicznym. Kluczowym mechanizmem jest zaburzona percepcja somatosensoryczna i interocepcja, nasilona przez negatywne czynniki psychologiczne, takie jak katastrofizacja, negatywna afektywność i unikanie behawioralne. Zaburzenie somatyczne często współwystępuje z zaburzeniami lękowymi, depresyjnymi oraz zespołem jelita drażliwego i przewlekłym bólem, a także jest powiązane z traumą i stresem psychospołecznym.

Patogeneza zaburzenia somatycznego

Zaburzenie somatyczne (ang. Somatic symptom disorder, SSD) charakteryzuje się wzmożoną świadomością doznań cielesnych połączoną ze skłonnością do interpretowania tych doznań jako przejawów choroby somatycznej. Mechanizmy leżące u podstaw tego zaburzenia są złożone i nie zostały jeszcze w pełni poznane, ale aktualne dane naukowe wskazują na wieloczynnikowe podłoże obejmujące aspekty biologiczne, psychologiczne i środowiskowe.12

Czynniki neurobiologiczne

Badania wskazują, że u pacjentów z zaburzeniem somatycznym występują zmiany w aktywności autonomicznego układu nerwowego. Pobudzenie autonomiczne pochodzące z endogennych związków noradrenergicznych może powodować tachykardię, wzmożoną motorykę żołądka, podwyższony poziom pobudzenia, napięcie mięśniowe oraz ból związany z nadaktywnością mięśniową.12 Te fizjologiczne efekty mogą przyczyniać się do występowania i utrzymywania się objawów somatycznych.

Istnieją również dowody na zmiany strukturalne i funkcjonalne w mózgu osób z zaburzeniem somatycznym. Badania obrazowe mózgu wykazały związek między zaburzeniem somatycznym a zmniejszoną objętością ciała migdałowatego oraz zmienioną łącznością między ciałem migdałowatym a obszarami mózgu kontrolującymi funkcje wykonawcze i motoryczne.3 Ponadto u pacjentów z tym zaburzeniem obserwuje się odmienne wzorce zmienności rytmu serca, co wskazuje na różnice w psychofizjologii.4

Stwierdzono również zmniejszoną gęstość komórek i zmiany w sygnalizacji radiologicznej w obszarach mózgu związanych z percepcją somatyczną i doświadczeniem emocjonalnym.5 Dodatkowo badania wskazują na możliwy udział procesów prozapalnych w rozwoju zaburzenia somatycznego, takich jak zwiększenie niespecyficznych objawów somatycznych i wrażliwości na bodźce bólowe.6

Podłoże genetyczne

Istnieją dowody na genetyczny komponent zaburzenia somatycznego. Badanie bliźniąt monozygotycznych i dizygotycznych wykazało, że udział czynników genetycznych w objawach somatycznych wynosi od 7% do 21%, podczas gdy pozostała część jest przypisywana czynnikom środowiskowym.78 W innym badaniu stwierdzono związek między objawami somatycznymi a kilkoma polimorfizmami pojedynczego nukleotydu.9

Badania konsanguiniczne i genotypowanie polimorfizmów pojedynczego nukleotydu wskazują, że zarówno czynniki genetyczne, jak i środowiskowe przyczyniają się do ryzyka wystąpienia zaburzenia somatycznego.10 Modyfikacje genetyczne związane z układem monoaminergicznym mogą być szczególnie istotne, choć wspólne źródło genetyczne pozostaje nieznane.11

Mechanizmy poznawcze i percepcyjne

Jednym z kluczowych mechanizmów w zaburzeniu somatycznym jest zaburzona percepcja doznań cielesnych. Osoby cierpiące na to zaburzenie wykazują wzmożoną świadomość normalnych doznań cielesnych połączoną z tendencją do interpretowania tych doznań jako objawów poważnej choroby.12 Ten mechanizm został zidentyfikowany jako styl poznawczy znany jako „wzmocnienie somatosensoryczne” (ang. somatosensorial amplification).13

U pacjentów z zaburzeniem somatycznym obserwuje się również zaburzenia w dokładności interocepcji (zdolności do percepcji bodźców wewnętrznych). Badania sugerują, że dokładność interocepcyjna u pacjentów z zaburzeniem somatycznym nie jest po prostu zwiększona lub zmniejszona, ale jest zniekształcona przez inne czynniki psychologiczne, które mogą wpływać na schematy poznawcze pacjenta dotyczące somatyzacji.14

Zaburzenie przetwarzania emocjonalnego jest uważane za jeden z najważniejszych czynników psychopatologicznych w zaburzeniu somatycznym. Zaburzenia aktywności autonomicznego układu nerwowego są bardziej wyraźne, gdy zaangażowane jest przetwarzanie emocjonalne.15

Czynniki psychologiczne

Negatywne czynniki psychologiczne, w tym katastrofizacja, negatywna afektywność, ruminacje, unikanie, lęk o zdrowie lub słaba koncepcja fizyczna siebie, mają znaczący wpływ na przejście od nieproblematycznych objawów somatycznych do poważnie upośledzającego zaburzenia somatycznego.16

Specyficzne negatywne czynniki psychologiczne (NPF), takie jak katastrofizacja, negatywna afektywność i unikanie behawioralne, mogą przyczyniać się do dysfunkcji u osób z zaburzeniem somatycznym i zaburzeniami depresyjnymi oraz mogą podtrzymywać objawy poprzez dysregulacje biologicznych systemów odpowiedzi na stres.17

Osoby z zaburzeniem somatycznym często mają negatywne postrzeganie swojego ciała i zdrowia.18 Ta negatywna percepcja może przyczyniać się do nadmiernego skupienia na objawach fizycznych i nieproporcjonalnej reakcji na te objawy.

Rola czynników stresowych i urazów

Stresory psychospołeczne i kultura wpływają na sposób, w jaki pacjenci prezentują się lekarzowi. Badania przeprowadzone w podstawowej opiece zdrowotnej wykazały znacznie wyższe wskaźniki bezrobocia i upośledzenia funkcjonowania zawodowego u pacjentów somatyzujących w porównaniu z pacjentami niesomatyzującymi (odpowiednio 29% vs. 15% i 55% vs. 14%).19

Czynniki ryzyka przewlekłych i poważnych objawów somatycznych obejmują zaniedbanie w dzieciństwie, wykorzystywanie seksualne, chaotyczny styl życia oraz historię nadużywania alkoholu i substancji psychoaktywnych. Ponadto zaburzenie somatyczne wiąże się z zaburzeniami osobowości.20

Istnieje związek między somatyzacją a historią wykorzystywania seksualnego lub fizycznego u znacznej części pacjentów.21 Wysoki odsetek pacjentów z zespołem stresu pourazowego również wykazuje somatyzację.22

Zaburzenia współistniejące i ich wpływ

Zaburzenie somatyczne często współwystępuje z innymi zaburzeniami psychicznymi, szczególnie z zaburzeniami lękowymi i depresyjnymi.23 Ta współchorobowość może wpływać na przebieg i nasilenie objawów somatycznych.

Badania wykazały wyższy odsetek zaburzenia somatycznego u osób z zespołem jelita drażliwego i u pacjentów z przewlekłym bólem.24 Somatyzacja może wpływać na utrzymywanie się i nasilenie objawów w chorobach żołądkowo-jelitowych.25

U pacjentów z zespołem po-COVID (PCS) wpływ zaburzenia somatycznego na upośledzenie życia codziennego wydaje się większy niż u pacjentów z astmą lub przewlekłą obturacyjną chorobą płuc (POChP).2627

Model biopsychospołeczny zaburzenia somatycznego

Coraz częściej zaburzenie somatyczne jest postrzegane przez pryzmat modelu biopsychospołecznego, który uwzględnia złożone interakcje między czynnikami biologicznymi, psychologicznymi i społecznymi.28

Hipotezy integracyjne

Istnieje kilka hipotez wyjaśniających mechanizmy leżące u podstaw zaburzenia somatycznego:

  • Hipoteza dysfunkcji osi podwzgórze-przysadka-nadnercza (HPA) – sugeruje, że długotrwała aktywacja tej osi w odpowiedzi na stres może prowadzić do objawów fizycznych.29
  • Hipoteza zaburzenia percepcji – przedstawia zaburzenie somatyczne jako zaburzenie percepcji, w którym percepcja doznań cielesnych powoduje niepokój.30
  • Hipoteza przeciążenia stresem – sugeruje, że nasze ciała produkują objawy somatyczne, gdy gromadzą zbyt wiele stresu.31
  • Hipoteza centralnej sensytyzacji – definiowana jako nadpobudliwość ośrodkowego układu nerwowego, przyczynia się do rozwoju i utrzymywania się przewlekłego bólu, a jej rola w innych objawach somatycznych jest przedmiotem debaty.32

Rola oczekiwań i wzmocnienia somatosensorycznego

Oczekiwania, definiowane jako przyszłościowo ukierunkowane poznanie dotyczące przewidywanego przebiegu objawów, są uważane za kluczowy element aktualnych modeli etiologicznych zaburzenia somatycznego (np. wzmocnienia somatosensorycznego).33

Unikalny sposób, w jaki każda osoba postrzega objaw somatyczny i jego nasilenie, oczekiwanie dotyczące tego, jak objaw będzie się rozwijał, oraz czy leczenie będzie skuteczne, zależy od konstelacji czynników biologicznych, psychologicznych i społecznych.34

Mechanizmy obronne i procesy nieświadome

Teoria psychodynamiczna sugeruje, że objawy somatyczne pojawiają się jako odpowiedź na nieświadome problemy emocjonalne.35 Według tego podejścia, osoby z zaburzeniem somatycznym mogą używać dysocjacji jako rodzaju mechanizmu obronnego w celu radzenia sobie z traumą lub nadużyciami.36

Obrazowanie przedczołowej kory mózgowej u osób z czynnościowym zaburzeniem neurologicznym (zaburzeniem konwersyjnym) pokazuje, że osoba z paraliżem z powodu tego zaburzenia próbuje poruszać sparaliżowaną częścią ciała, ale nie jest w stanie, co dowodzi, że pacjent nie symuluje swoich problemów; raczej nie jest w stanie wykonać zamierzonej czynności z powodu rozłączenia regionów mózgu odpowiedzialnych za połączenie świadomej woli z możliwością jej zrealizowania.37

Implikacje diagnostyczne i terapeutyczne

Zrozumienie patogenezy zaburzenia somatycznego ma kluczowe znaczenie dla odpowiedniego diagnozowania i leczenia tego zaburzenia.38

Podejście diagnostyczne

W DSM-5 zaburzenie somatyczne zostało na nowo zdefiniowane, kładąc nacisk na diagnozę stawianą na podstawie pozytywnych objawów i oznak (dokuczliwe objawy somatyczne plus nieprawidłowe myśli, uczucia i zachowania w odpowiedzi na te objawy), a nie na braku medycznego wyjaśnienia objawów somatycznych.39

Wyróżniającą cechą wielu osób z zaburzeniami somatycznymi nie są same objawy somatyczne, ale sposób, w jaki je prezentują i interpretują.40 To podejście diagnostyczne pozwala uniknąć dualizmu umysł-ciało i równania medycznie niewyjaśnionych objawów z objawami psychogennymi.41

DSM-5 wyraźnie pozwala na zdiagnozowanie zaburzenia somatycznego oprócz współistniejącej choroby somatycznej.42 Oznacza to, że obecność objawów somatycznych ustalonego zaburzenia medycznego (np. cukrzycy lub choroby serca) nie wyklucza diagnozy zaburzenia somatycznego, jeśli spełnione są kryteria.43

Implikacje terapeutyczne

Leczenie zaburzenia somatycznego wymaga wieloaspektowego podejścia dostosowanego do indywidualnego pacjenta. W wyborze odpowiedniego planu leczenia lekarze podstawowej opieki zdrowotnej powinni brać pod uwagę czynniki psychologiczne, społeczne i kulturowe, które wpływają na objawy somatyczne.44

Ogólne zasady leczenia obejmują:

  • Planowanie regularnych wizyt o krótkich odstępach czasu, aby uniknąć konieczności występowania objawów w celu uzyskania wizyty
  • Ustanowienie współpracy i terapeutycznego sojuszu z pacjentem
  • Uznanie i legitymizację objawów po ocenie pacjenta pod kątem innych chorób medycznych i psychiatrycznych
  • Ograniczenie testów diagnostycznych
  • Zapewnienie pacjenta, że poważne choroby zostały wykluczone
  • Edukowanie pacjentów na temat radzenia sobie z objawami fizycznymi
  • Wyznaczenie celu leczenia jako poprawy funkcjonowania, a nie wyleczenia
  • Odpowiednie kierowanie pacjentów do specjalistów i specjalistów zdrowia psychicznego45

Udowodnione terapie prowadzone przez specjalistów zdrowia psychicznego obejmują terapię poznawczo-behawioralną i terapię opartą na uważności.46 Terapia poznawczo-behawioralna (CBT) skutecznie zmniejsza nasilenie objawów somatycznych, a długoterminowe utrzymanie tych popraw zostało osiągnięte.47

Leczenie zaburzenia somatycznego ma na celu zarządzanie objawami fizycznymi oraz psychologicznymi za pomocą psychoterapii (terapii rozmową) i czasami leków, które leczą podstawowy lęk i depresję.48

Podejście biopsychospołeczne do leczenia

Model biopsychospołeczny leczenia jest jednym z najbardziej skutecznych w przypadku zaburzeń somatycznych, ponieważ uwzględnia różne czynniki biologiczne, psychologiczne i społeczne, które wpływają na chorobę i prezentowane objawy, oraz obejmuje podejście multidyscyplinarne.49

Celem leczenia zaburzenia somatycznego jest kompleksowe zarządzanie objawami fizycznymi, jak i psychologicznymi za pomocą psychoterapii i czasami leków łagodzących podstawowe objawy lęku i depresji.50

Pacjenci z zaburzeniem somatycznym, tak jak wszyscy ludzie, mogą następnie rozwinąć ogólne zaburzenia medyczne, dlatego należy przeprowadzać odpowiednie badania i testy, gdy objawy znacząco się zmieniają, pojawiają się nowe objawy lub pojawiają się obiektywne oznaki.51

Nowe kierunki badań i wyzwania

Pomimo postępów w zrozumieniu patogenezy zaburzenia somatycznego, nadal istnieją znaczące luki w wiedzy i wyzwania w badaniach i praktyce klinicznej.52

Luki w badaniach

Obecny brak badań badających częstość występowania zaburzenia somatycznego w oparciu o wywiady według standardowych kryteriów jest główną luką badawczą, uniemożliwiającą wiarygodne oszacowanie częstości występowania tego zaburzenia.53

Dowody dotyczące rozwoju, przebiegu i czynników ryzyka zaburzenia somatycznego są niestety skąpe i charakteryzują się nieprecyzyjną operacjonalizacją diagnozy, często związaną z wcześniejszymi koncepcjami diagnostycznymi.54

Mechanizmy somatycznych objawów uporczywych w chorobach somatycznych są słabiej zbadane niż w zaburzeniach czynnościowych i somatoformicznych.55

Wyzwania diagnostyczne

Zaburzenia psychiczne, które charakteryzują się objawami somatycznymi, są często trudne do zdiagnozowania ze względu na ich internalizującą naturę, co oznacza, że nie ma realnego sposobu, aby klinicysta mógł zmierzyć objaw somatyczny.56

Diagnoza różnicowa w zaburzeniu somatycznym rzadko była badana. Konieczne są dalsze badania, aby zbadać, w jaki sposób i czy zaburzenie somatyczne i zaburzenie lękowe o chorobę różnią się od siebie.57

Dla klinicystów, postawienie i przekazanie diagnozy zaburzenia somatycznego może być trudne.58 Kiedy klinicyści spotykają rodzinę, która nie jest jeszcze gotowa, aby rozważyć połączenie umysł-ciało jako część stanu ich dziecka, pomimo znacznych ograniczeń funkcjonalnych, obie strony mogą czuć się w martwym punkcie.59

Kontrowersje i debaty

Łączenie wcześniejszych diagnoz w zaburzenie somatyczne nie odbywało się bez kontrowersji.60 Kluczowym wnioskiem jest to, że upośledzenie funkcjonowania nie wynika z samych objawów somatycznych, ale ze sposobu, w jaki osoba je prezentuje i interpretuje, co powoduje znaczny dyskomfort.61

Stosowanie kryteriów diagnostycznych zaburzenia somatycznego/zaburzenia stresu somatycznego (SSD/BDD) niesie ryzyko fałszywego etykietowania osób z fibromialgią jako cierpiących na dominującą chorobę psychiczną.62

Eksperci w dziedzinie fibromialgii wyrazili obawy, że definicja ICD-11 przekształciła fibromialgię w wieloukładowe zaburzenie bólowe, odrębne od układu mięśniowo-szkieletowego.63 Pojęcie katastrofizacji bólu jest dobrze ustalone w badaniach nad fibromialgią i opiece klinicznej, z nakładaniem się na kryteria SSD B1 i B2.64

Idealną opieką dla fibromialgii jest ta, która obejmuje zasady podejścia biopsychospołecznego i wartość terapii psychologicznych oraz podkreśla znaczenie czynników psychospołecznych w predyspozycji, wyzwalaniu i utrwalaniu objawów fibromialgii oraz związanej z nią niepełnosprawności.65

Przyszłe kierunki badań

Lepsze zrozumienie wieloczynnikowych mechanizmów utrzymywania się objawów jest kluczowe dla opracowania ukierunkowanych interwencji opartych na mechanizmach w celu skutecznego zapobiegania i leczenia uporczywych objawów somatycznych.66

Zbadane zostały niektóre potencjalne dodatkowe cechy zaburzenia somatycznego, np. skanowanie ciała, zaprzeczanie chorobie i samokoncepcja słabości cielesnej.67

Proponowana jest nowa klasyfikacja zaburzeń czynnościowych somatycznych, która nie jest ani czysto somatyczna, ani czysto psychiczna, ale zajmuje neutralną przestrzeń między tymi dwoma historycznymi biegunami. Odzwierciedla to zarówno pojawiające się dowody etiologiczne dotyczące złożonych interakcji między mózgiem a ciałem, jak i potrzebę rozwiązania historycznego podziału między zaburzeniami somatycznymi a psychicznymi.68

    The cause of somatic symptom disorder is unknown. Symptoms may result from a heightened awareness of specific physical sensations paired with a tendency to interpret these experiences as signs of a medical ailment.[2] […] Evidence suggests that along with more broad factors such as early childhood trauma or insecure attachment, negative psychological factors including catastrophizing, negative affectivity, rumination, avoidance, health anxiety, or a poor physical self-concept have a significant impact on the shift from unproblematic somatic symptoms to a severely debilitating somatic symptom disorder.[18] […] It has been suggested that proinflammatory processes may have a role in somatic symptom disorder, such as an increase of non-specific somatic symptoms and sensitivity to painful stimuli.[28]

Symptoms may result from a heightened awareness of specific physical sensations paired with a tendency to interpret these experiences as signs of a medical ailment.[2] […] Evidence suggests that along with more broad factors such as early childhood trauma or insecure attachment, negative psychological factors including catastrophizing, negative affectivity, rumination, avoidance, health anxiety, or a poor physical self-concept have a significant impact on the shift from unproblematic somatic symptoms to a severely debilitating somatic symptom disorder.[18] […] It has been suggested that proinflammatory processes may have a role in somatic symptom disorder, such as an increase of non-specific somatic symptoms and sensitivity to painful stimuli.[28]

    Persistent somatic symptoms cause strong impairment in persons with somatic symptom disorder (SSD) and depressive disorders (DDs). […] Specific negative psychological factors (NPFs), such as catastrophizing, negative affectivity, and behavioral avoidance, are assumed to contribute to this impairment and may maintain symptoms via dysregulations of biological stress systems. […] NPFs may be considered as transdiagnostic factors in the development and treatment of impairing somatic symptoms.

    https://www.theravive.com/therapedia/somatic-symptom-disorder-dsm–5-300.82-(f45.1)
    Somatic symptom disorder (SSD) is characterized as recurring and multiple physical complaints that begin before the age of 30. […] Under DSM-IV criteria, somatic symptoms had to be medically unexplained for a diagnosis of somatic symptom disorder. If the symptom could be explained by a medical disorder then a diagnosis of SSD could not be made. This requirement, or mind-body dualism, is removed under DSM-5. Somatic symptom disorder can coexist with a medical disorder. […] The DSM-5 identifies risk factors for somatic syndrome disorder as family history and genetics, early traumatic experiences, learning that illness attracts attention and cultural and social norms. […] A common feature of individuals with SSD is a negative perception of their body and health. […] While psychological disorders often underlie somatic disorders, those with SSD first seek medical assistance from a family physician in the belief they have a physical ailment.

    Somatic symptoms may result from a heightened awareness of certain bodily sensations, combined with a tendency to interpret these sensations as indicative of a medical illness. The etiology of somatic symptom disorder is unclear. However, studies have determined that risk factors for chronic and severe somatic symptoms include childhood neglect, sexual abuse, chaotic lifestyle, and a history of alcohol and substance abuse. In addition, somatic symptom disorder has been associated with personality disorders. […] Psychosocial stressors and culture affect how patients present to the physician. For example, studies in primary care settings found significantly higher rates of unemployment and impaired occupational functioning in somaticizing patients compared with nonsomaticizing patients (29% vs. 15%, and 55% vs. 14%, respectively).

    The aim was to compare the relationship between somatic symptom disorder (SSD), anxiety, depression, clinical symptoms, and daily life impairment (DLI) in post-COVID syndrome (PCS), asthma and chronic obstructive pulmonary disease (COPD). […] SSD appears to have greater impact on DLI in PCS than asthma or COPD patients.

[…] Previous studies have shown that SSD and psychological factors, particularly anxiety and depression, are associated with symptom persistence and DLI after SARS-CoV-2 infection. […] The high proportion of DLI in patients suffering from PCS can probably best be explained by the patient selection itself, as these are patients who were assigned to the rehabilitation program due to their poor state of health.

    Experts have noted that for patients with SSD, anxiety is the driving force underlying the disproportionate reaction to their symptoms. Anxiety in the context of SSD can manifest as rumination, repetitive checking behaviors to manage the distress, and concerns about the implications of their bodily sensations. […] Although there is no universal consensus on the mechanism underlying SSD, patients may benefit from hearing hypothesized pathways of symptom production. We can explain the physiologic fight-or-flight response and how persistent activation of the hypothalamic-pituitary axis (HPA) produces physical symptoms. Some patients may prefer the use of metaphors in understanding their condition, such as likening the patients symptoms to a software bug rather than a critical issue with their hardware. Henningsen describes SSD as a disorder of perception, in which the patients perception of their bodily sensations causes them alarm. Depending on their acceptance of the mind-body connection, some patients may resonate with the stress overload hypothesis in which our bodies produce somatic symptoms when holding on to too much stress. The explanation used will vary between patients and is ultimately dependent on the patient-provider relationship.

    The comprehensive vulnerability-stress model by Henningsen et al. defines predisposing, triggering and maintaining/aggravating factors that determine the transition from short-term to persistent disabling symptoms. […] Sufficient evidence warrants the assumption that aetiological mechanisms derived from research on somatoform and functional disorders also contribute to the persistence of symptoms in somatic diseases. […] However, the applicability of generic and specific risk factors and mechanisms of PSS across medical diseases has yet to be investigated. […] Central sensitisation, defined as hyperexcitability of the central nervous system, has been suggested to contribute to the development and maintenance of chronic pain, while its role in other PSS is under debate.

    Persistent somatic symptoms (PSS) are highly prevalent in all areas of medicine; they are disabling for patients and costly for society. […] Initial evidence indicates that, in addition to disease-specific pathophysiological processes, psychological factors such as expectations, somatosensory amplification and prior illness experiences contribute to symptom persistence in functional as well as in somatic diseases. […] A better understanding of the multifactorial mechanisms of symptom persistence is crucial for developing targeted mechanism-based interventions for effective prevention and treatment of PSS. […] The aetiology of PSS across somatic diseases is not well understood. […] The unique way in which each individual perceives a somatic symptom and its severity, the expectation on how the symptom will evolve, and whether the treatment will be effective depends on the constellation of biological, psychological and social factors.

    SSD as a diagnosis was introduced in 2013 with the publication of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). SSD is characterized by intense psychological distress (thoughts, feelings, and behaviors) related to physical symptoms (bodily distress) that lasts for more than 6 months. SSD has replaced the DSM-IV diagnosis of somatization disorder, removing the criterion of medically unexplained symptoms. The core feature of this newly defined disorder is the degree of the patients psychological reaction to the symptoms, and the impact of that reaction on their ability to function, rather than on the presence or absence of a medical condition to explain the patients symptoms. The diagnostic criteria for SSD are straightforward compared to those for somatization disorder, which require a certain number of medically unexplained symptoms spread across several organ systems. This new conception of the illness as focusing on the psychological reaction to the symptoms rather than the cause of the symptoms is intended to reduce the stigma many patients have experienced with the diagnosis of somatization disorder and the commonly held interpretation that this means its all in your head. With a diagnosis of SSD, treatment will include techniques to address the thoughts, feelings, and behaviors of the patient in response to the somatic symptoms, with the goal of enabling the patient to engage in meaningful life activities despite having these sensations.

[…] Patients with somatic symptom disorder, like all individuals, may subsequently develop general medical disorders, thus, appropriate examinations and tests should be done when symptoms change significantly, new symptoms develop, or objective signs develop.

    Individuals with somatic symptom disorder often present with multiple somatic symptoms at one time. […] Somatic symptom disorder is often diagnosed when another medical condition is present, as these two diagnoses are not mutually exclusive. […] Somatic symptom disorder patients generally present with significant worry about their illness. […] Psychological disorders that feature somatic symptoms are often challenging to diagnose due to the internalizing nature of the disorder, meaning there is no real way for a clinician to measure the somatic symptom. […] Psychodynamic theory suggests that somatic symptoms present as a response against unconscious emotional issues. […] Cognitive theorists often believe that somatic disorders are a result of negative beliefs or exaggerated fears of physiological sensations.

    For clinicians, making and conveying a diagnosis of an SSRD can be difficult. […] Long-term psychotherapeutic management strategies are beyond scope of this document but should be part of treatment planning. […] A holistic approach considers the dual role of physical and mental health conditions that may be contributing to ultimate diagnoses. […] Explain the mind-body connection and normalize somatization. […] Emphasize that symptoms may be understood as a problem with software rather than hardware. […] Many children or adolescents with an SSRD have co-occurring psychiatric disorders with or without overlapping symptoms, such as anxiety, depression, or an eating disorder. […] Such conditions should be treated concurrently, as per usual guidelines, with the most impairing psychiatric disorder prioritized.

    The role of rehabilitation for treating SSRDs lacks high quality, evidence-based studies, but the chronic pain literature makes it clear that a multi-modal approach, including rehabilitation services, supports recovery. […] When clinicians encounter a family that is not yet ready to consider the mind-body connection as part of their child’s condition despite significant functional limitations, both parties can feel stuck. […] Reassure families that focusing on rehabilitation does not preclude further testing or diagnosis, but rather is intended to support their child and prevent decline.

    For diagnosis, these latter mental disorders require at least one distressing somatic symptom (e.g. pain) plus positive psychobehavioral criteria, namely excessive thoughts, feelings, or behaviours related to the somatic symptoms or associated health concerns, without the condition that distressing somatic symptoms have to be medically unexplained. […] The use of the somatic symptom disorder/bodily distress disorder diagnostic criteria risk falsely labelling people with fibromyalgia syndrome as having a predominant mental illness. […] The diagnostic category of somatoform and related disorders has been deleted following debate on the underlying concept of somatization and the uncertainties about excluding a physiological process or a physical disorder to explain the pain. […] The most fundamental revision for both the SSD and BDD has been to eliminate the distinction between medically explained and unexplained somatic complaints.

    Persistent somatic symptoms (PSS) are highly prevalent in all areas of medicine; they are disabling for patients and costly for society. […] Initial evidence indicates that, in addition to disease-specific pathophysiological processes, psychological factors such as expectations, somatosensory amplification and prior illness experiences contribute to symptom persistence in functional as well as in somatic diseases. […] A better understanding of the multifactorial mechanisms of symptom persistence is crucial for developing targeted mechanism-based interventions for effective prevention and treatment of PSS. […] The aetiology of PSS across somatic diseases is not well understood. […] The unique way in which each individual perceives a somatic symptom and its severity, the expectation on how the symptom will evolve, and whether the treatment will be effective depends on the constellation of biological, psychological and social factors.

    We propose a new classification of functional somatic disorder that is neither purely somatic nor purely mental, but occupies a neutral space between these two historical poles. This reflects both emerging aetiological evidence of the complex interactions between brain and body and the need to resolve the historical split between somatic and mental disorders.
