6 History  n 16Th century : Description of one OCD variant (scrupulosity) n 1903 : First description of OCD in childhood (in a 5y old boy by Pierre Janet ) old boy by Pierre Janet ) n 1927 : First survey of OCD in childhood (by catholic church that found 4% scrupulosity in female catholic highschool students) n 1935 : Leo Kanner described the social isolation of OCD youngsters & family overinvolvement in child`s rituals n 1942 : Berman described the similarities of childhood OCD & adult OCD OCD & adult OCD

7 History  n 1955 : Louise Despert noticed the tendency of children to hide OCD symptoms & that childhood OCD is more prevalent in boys n 1980s: Epidemiology Catchment Area (ECA) study finds that most adults with OCD report onset by adolescence n NIMH : The first systematic studies of epidemiology, phenomenology & psychopharmacology of OCD in children & adolescents

8 Epidemiology  n Difficult to Study Prevalence & Epidemiology n Where should the line demarcating Subclinical OC Features/Clinical OCD be drawn ? n Parents with Subclinical OC can`t recognize Symptoms in their Child ! n Secretiveness & No Insight in Patients n Unfamiliarity with Diagnosis & Treatment among Physicians n Underdiagnosed & Undertreated n Hidden Epidemic n Prevalence % n Lifetime Prevalence % n Subclinical OC up to 20.0 %

9 Epidemiology  n 1/4 of Subclinical OC / OCPD : full OCD Criteria at follow up n Bimodal Age of Onset : Child mean onset 10 y (40% <15 y) Child mean onset 10 y (40% <15 y) Adult mean onset 21 y Adult mean onset 21 y n Onset : Boys : Prepubertal ( girls< boys ) Boys : Prepubertal ( girls< boys ) Girls : Pubertal ( girls= boys ) Girls : Pubertal ( girls= boys ) n Early Onset OCD more likely : Boy, Genetic, Positive Family History for OCD & Tic Disorder Boy, Genetic, Positive Family History for OCD & Tic Disorder

10 Etiology n Neuropsychiatric Dis., Unknown & Heterogeneous Et. n Abnormal Corticostriatal-Thalamocortical Pathway n Frontal Lobe,Limbic System,Basal Ganglia Dysfunction n Abnormal Circuit linking Basal Ganglia to Cortex n Basal Ganglia Damage ( injury, tumor, CO poisoning, Encephalitis,… ) n Serotonin Hypothesis :Serotonin - Dopamine Dysregulation n Genetic (more concordance in MZ,20 % OCD in first relatives - with different symptoms & no modeling ) n Abnormal CNS Oxytocin Metabolism n Environmental Triggers

11 Clinical Presentation  n Similar to Adults ( no relationship between age & symptoms ) n Most endorsed all common symptoms at some point n Most experience wide variety of OC sympt. over time n Symptoms wax & wane over time n Most Obsession + Compulsion ( only obsessions or only compulsions are rare ) n Stress exacerbate OC symptoms n Generally reach clinical attention y after onset n Most not neat, compliant or attentive outside sympt. ( Disorganization + Perfectionism ) n Children want parents to collaborate ( patient & parent entwined in rituals )

12 Clinical Presentation  n Often Secretive & Embarrassed about Symptoms n Attempt to Deny, Minimize & Disguise Rituals ( I can stop any time I want ! ) ( I can stop any time I want ! ) n Some Deny any Anxiety or Distress n Some recognize Compulsions & Rituals but can`t relate them to specific Obsessions n Some Anxious & Perfectionist n May become Defiant, Demanding & Assaultive to perform Compulsions n Timing, Severity & Content are important for Diagnosis

16 Clinical Presentation  excessive moralizationtouching,counting erasing papers excessively rereading paragraphs ordering,arranging symmetry fear of having an illness excessive cleaning & washing dermatitis

17 Comorbidity n Up to 75 % Anxiety Dis. n Up to 70 % Mood Dis. (often follows OCD - commonly Depression ) n Up to 50 % ODD or ADHD (often precedes OCD ) n Up to 50 % Tic Dis. (by adulthood OC sympt. accompany Tic Dis. in 50 % ) n Up to 15 % OCPD ( some develop OCPD as coping ) n Some have impairments in visual-motor, visual- memory & executive functions n Up to 80 % Comorbidity n Those psychiatric disorders are high even in their first relatives !

18 Tic -Related Early Onset OCD n Tic /OCD may be different manifestations of same gene ! n Tic /OCD : high rate of TIC /OCD in first relatives n Girls < Boys n Earlier Onset n touching,rubbing,blinking,staring,symmetry, exactness,incompleteness,intrusive aggressive thoughts,hoarding,ordering,repeating,counting, exactness,incompleteness,intrusive aggressive thoughts,hoarding,ordering,repeating,counting, just so... just so... n less satisfaction with SSRI alone ! n Non-Tic Related OCD : cleaning,checking,...

19 PANDAS Pediatric Autoimmune Neuropsychiatric Disorder associated with Streptococcal Infection n Autoimmune Subgroup of OCD n Ab against GABHS cross-reacts with Caudate Tissue n Can cause OCD, Tic, Sydenham Chorea n Abrupt early-onset/exacerbation of OCD/Tic symptoms after Respiratory Tract Infection (GABHS) n Acute worsening of symptoms + remission periods n May cause dramatic deterioration n Often have neurological signs n Throat Culture, ASOT, Anti DNA GABHS, ANA n Treatment is still under investigation ! n Plasmapheresis, IV Immunoglubuline, Penicillin Prophylaxis

20 Differential Diagnosis n Allergic Reaction to Wasp Sting n Post Viral Encephalitis n Sydenham Chorea n Prader-Willi Syndrome n High dose Stimulants n Dopamine Agonists n Benign Habits n Developmentally Normal OC like Symptoms ( 2/3 of 2-4y Preschool Children ) OC symptoms may be seen in :. n Mood Dis.(mostly Depression) Depression) n Anxiety Dis. n Mental Retardation n PDD n Tic Disorder n Brain Damage n CNS Tumors n CNS Injuries n TLE n CO Poisoning

Poor Prognosis : n parental psychopathology n history of Tic or ODD n high EE in family n poor response to treatment

22 Treatment  n Choice : SRI + CBT SSRI : SSRI : n First Line n effectiveness in children = adults n response rate % n % typical symptom reduction n Fluoxetine ……… mg n Fluvoxamine … mg (8y<) n Sertraline …… mg (6y<) n Paroxetine …… mg n Citalopram …… mg

26 Treatment  Augmentation : n only after failing of : 2 SSRIs trial + 1 CBT course n If Anxious : augment with Buspirone 5-30 mg ; Clonazepam mg ; Risperidone 1-6 mg Buspirone 5-30 mg ; Clonazepam mg ; Risperidone 1-6 mg n If Affective Symptoms : augment with Lithium meq/lit ; Risperidone 1-6 mg Lithium meq/lit ; Risperidone 1-6 mg n If Tic, schizo-obsessive symptoms ; Schizotypal Personality : augment with Haloperidol 1-15 mg ; Risperidone 1-6 mg ; Clonazepam mg Haloperidol 1-15 mg ; Risperidone 1-6 mg ; Clonazepam mg

27 Treatment  n If months symptom-free : Decrease Dose 25 % Q 2 months Decrease Dose 25 % Q 2 months n Continue CBT booster sessions n Many require long-term maintenance ! n OCD + Tic or Schizotypal Personality or soft neurological signs : No well response to SRI

28 Treatment  CBT : n response rate % n typical symptom reduction % n sessions (booster sessions needed time to time !) (booster sessions needed time to time !) 1) Information gathering 1) Information gathering 2) Rank ordered list : Least difficult ones first ! 2) Rank ordered list : Least difficult ones first ! 3) Therapist assisted systematically 3) Therapist assisted systematically Exposure/Response Prevention Exposure/Response Prevention 4) Homework assignment 4) Homework assignment
