7 Somatoform and related disorders ICD-10 (F45.X) Somatisation Disorder Undifferentiated SD Hypochondriacal Disorder Persistent Somato. Pain Disorder Somatoform Autonomic Dysfunction SD unspecified Dissociative Disorder Neurasthenia (F48.0) Factitious Disorder (F68.1)

8 Definition af somatoforme lidelser (ICD-10) gentagen forekomst af fysiske symptomer samt vedholdende anmodninger om lægelig undersøgelse på trods af, at der gentagne gange ikke er fundet noget galt og på trods af beroligelse fra læger om, at symptomerne ikke skyldes nogen fysisk sygdom. Patienterne er krævende er vedholdende kan ikke overbevises om, at de ikke fejler noget (fysisk)

Møde i europæisk ekspertgruppe, maj 2009 gennemgang af termer Functional disorders and functional somatic syndromes Bodily distress disorder or bodily stress disorder Somatic symptom disorder Somatoform disorder

11 Definition af funktionelle lidelser (som sygdom) En funktionel lidelse er en sygdom, hvor man har fysiske symptomer, som gør det svært at fungere i dagligdagen. Den præcise årsag kendes ikke, men man kan forstå det som en sygdom, hvor hjernen og kroppen af forskellige årsager er overbelastet og ikke fungerer normalt. funktionellelidelser.dk 2011

14 Sygehistorie BDS, 26-årig kvinde Hun har fået diagnosen fibromyalgi og kronisk træthedssyndrom, ligesom mange andre sygdomme har været overvejet. Hun har været igennem alle tænkelige undersøgelser, selv de mest avancerede, der kun bruges i forskningsøjemed på universitetshospitalerne, men uden at et organisk grundlag er fundet. Kvinden har alarm i hjemmet samt diverse handicaphjælpemidler, og hun er tilknyttet hjemmesygeplejen. Hun står foran indstilling til pension. Ved undersøgelser stilles diagnosen somatiseringstilstand, som er den mest kroniske af de funktionelle lidelser. I dag Bodily distress syndrome, multi-organ type.

15 Functional somatic syndromes by speciality Gastroenterology Gynaecology Rheumatology Cardiology Respiratory medicine Infectious diseases Neurology Dentistry Ear, nose and throat Allergy Irritable bowel syndrome (IBS), non-ulcer dyspepsia Pelvic arthropathy, premenstrual syndrome, chronic pelvic pain Fibromyalgia, lower back pain Atypical or non-cardiac chest pain, syndrome-x Hyperventilation syndrome Chronic fatigue syndrome (CFS, ME) Tension headache, pseudo-epileptic seizure Temporomandibular joint dysfunction, atypical facial pain Globus syndrome Multiple chemical sensitivity (MCS)? Electricity hypersensitivity? Infrasound hypersensitivity Orthopaedics Anaesthesiology Psychiatry WAD whiplash ass. disorder Chronic benign pain syndrome Somatoform disorders, Neuroastenia, Dissociative (conversion)

26 ETIOLOGY There are many causes for functional disorders.

27 Årsager Sårbarhed: Biologiske, psykologiske og sociale Arv, social indlæring, tidligere sygdom, seksuelle overgreb Sygdom Kronisk sygdom PER FINK PROF., DR.MED., PH.D.

28 Stress Cardio-pulmonary arousal Bodily distress Autonomic arousal & HPA axis hyperactivity Gastro-intestinal arousal Unspecific sensitivity to bodily symptoms General stress response Muskulosceletal tension

29 Biological factors Increased symptom production Pathological central processing and modulation of body signals

30 Årsager Sårbarhed: Biologiske, psykologiske og sociale Arv, social indlæring, tidligere sygdom, seksuelle overgreb Udløsende faktorer: Infektion eller anden fysisk sygdom Fysisk eller psykisk traume, stress eller belastning Lægen Tilfældigt fund ved undersøgelse Sygdom Vedligeholdende faktorer: Uhensigtsmæssige antagelser om symptomer og sygdommen Uhensigtsmæssig sygdomsadfærd Øget følsomhed af hjernen Sundhedssystemet Social og økonomisk afhængighed Kronisk sygdom PER FINK PROF., DR.MED., PH.D.

37 Treatment of functional disorders

38 Udfordringer Sikre patienter med funktionelle lidelser den samme behandlingskvalitet som alle andre patienter.

39 Bodily Distress Syndrome Assumption The patients misinterprete normal physical sensations as indication of severe disease Preoccupation with their physical health and bodily sensations High health care use frequent attenders Reality The case in health anxiety but not in BDS. The patients have their symptoms Suffering from symptoms The patients cannot get any help or explanations A problem of the health care system It is a chronic illness The same spectrum as in other disorders/diseases Unresponsive to therapy The symptoms represent a (disguised) mental disorder Quite good treatment results even in the chronic group The problem is physical symptoms. It is a distinct disorder of its own

40 Misforhold mellem patientens forventninger og det lægen tilbyder Hvad patienten vil Kende årsagen Have forklaringer og information Have råd og behandling Have beroligelse Tages seriøst af en forstående og kompetent læge Ønsker emotionel støtte Hvad patienten får Ingen diagnose Dårlige forklaringer, der ikke omhandler deres behov eller bekymringer Utilstrækkelige råd Manglende beroligelse En følelse af, at lægen er uinteresseret eller mener symptomerne ikke er vigtige Ingen emotionel støtte

41 Funktionelle tilstande et spektrum 6 mdr. Normale fysiologiske reaktioner Forbigående symptomer Lette funktionelle symptomer Bodily distress syndrome = BDS Let grad af funktionelle symptomer Svær grad af funktionelle symptomer

42 Den somatiske afdelings/læges rolle i behandlingen af patienter med funktionelle lidelser Ekskludér (inden for rimelighedens grænser) somatisk lidelse eller skader, der kan behandles. Giv på empatisk måde patienten klar besked om, at der er/ikke er fundet tegn på organisk sygdom inden for ens eget speciale. Forklar patienten, at der ikke er lægelig indikation for flere somatiske undersøgelser. Sober og professionel behandling. Stil diagnosen funktionel tilstand (eller lignende betegnelse). Undgå at påføre patienten skader eller gøre denne mere syg. Forsøg at respondere på patientens udtalte og uudtalte spørgsmål og forventninger. Koordiner behandlingen med egen læge og evt. andre behandlere, patienten er i kontakt med. Overvej henvisning til psykiatrisk vurdering eller specialenhed. Se i øvrigt råd ved kroniske tilstande.
