  3. Early detection and prevention in another illness “If you catch cancer at Stage 1 or 2, almost everybody lives. If you catch it at Stage 3 or 4, almost everybody dies. We know from cervical cancer that by screening you can reduce cancer up to 70 percent. We’re just not spending enough of our resources working to find markers for early detection.” ---Lee Hartwell, MD Nobel Laureate, Medicine President and Director, Hutchinson Center New York Times Magazine December 4, 2005, p. 56

  5. $10 million Lifetime costs for each new case of schizophrenia

  6. 25 Years of life lost by people with schizophrenia due to all causes, including heart disease, cancer and suicide

  7. Functioning as an effect of number of psychotic episodes

  8. Empirical evidence for a relationship between a long DUP and a poor prognosis • Johnstone et al. 1986: Many psychotic patients did not get appropriate treatment early, even when they sought help. • Crow et al. 1986: DUP more important for the course than maintenance medication. • Rabiner et al 1986: Long DUP was related to a poor one year outcome. • Wyatt 1991,Opjordsmoen 1991: Earlier treatment predicted better course.

  9. Effects of untreated initial psychosis • Being psychotic is a personal disaster and the longer it lasts, the more it can become traumatic and stigmatizing. • Being psychotic reduces cognitive and social function. They may lose contact with family and friends, fail school, or drop out of work. • The longer the psychosis lasts, the more difficult it may be for the therapist to establish a good therapeutic relationship with the patient. • Neurobiological deficit processes linked to symptom formation may possibly proceed unlimited as long as the patient is untreated.

  10. Validity of diagnosis across phases of illness Neurological disease (Cerebral AIDS, SLE, MS. etc.) High Premorbid period Prodromal period Defined Diagnosis Dementia praecox, deficit schizophrenia Chronic undifferentiated schizophrenia Paranoid schizophrenia Schizo-obsessive disorder. 0 Validity of clinical differential diagnosis Schizo-affective disorder “NRG-1 disorder” Psychotic bipolar disorder Psychotic depressive disorder High Severe agoraphobia time

  20. Social networks in schizophrenia • Family network size • diminishes with length of illness • decreases in the period immediately following a first episode • is smaller at the time of first admission • Networks • buffer stress and adverse events • determine treatment compliance • predict relapse rate • correlate with coping skills and burden.

  21. Is early intervention indicated prevention of psychotic disorders? Probably “Yes, we can?”

  22. Trials of Indicated Prevention • Buckingham, UK • EDIE, UK • German Research Network • OPUS, Denmark • TIPS, Norway, Denmark • PACE, Australia • PRIME, North America • Omega-3 FAs, Austria • PIER, Maine • EDIPPP, USA

  23. Psychosis prevention studies: One year rates for conversion to psychosis

  24. Portland Identification and Early Referral(PIER) Reducing the incidence of major psychotic disorders in a defined population, by early detection and treatment: Indicated prevention

  25. Project Overview

  26. BIOLOGICAL RISK FACTORS Greater Portland Area Population 33O,OOO

  27. Experimental Catchment Area:Vital statistics

  28. Professional and Public Education • Reducing stigma • Information about modern concepts of psychotic disorders • Increasing understanding of early stages of mental illness and prodromal symptoms • How to get consultation, specialized assessments and treatment quickly • Ongoing inter-professional collaboration

  29. Youth Education • Public service announcements by mainstream television and health information programs • Interviews and spot announcements by youth television cable network • 2-3 sessions on early warning signs as part of the obligatory 10th grade health curriculum • Widespread distribution of bookmarks and posters throughout catchment area schools, colleges, bookstores • Art and literature contest • Major publicity events during Mental Illness Awareness Week • Youth oriented website: www.preventmentalillness.org

  33. Clinical Strategies

  34. Signs of prodromal psychosisSchedule of Prodromal Syndrome (SOPS), McGlashan, et al • A clustering of the following: • Changes in behavior, thoughts and emotions, with preservation of insight, such as: • Heightened perceptual sensitivity • To light, noise, touch, interpersonal distance • Magical thinking • Derealization, depersonalization, grandiose ideas, child-like logic • Unusual perceptual experiences • “Presence”, imaginary friends, fleeting apparitions, odd sounds • Unusual fears • Avoidance of bodily harm, fear of assault (cf. social phobia) • Disorganized or digressive speech • Receptive and expressive aphasia • Uncharacteristic, peculiar behavior • Satanic preoccupations, unpredictability, bizarre appearance • Reduced emotional or social responsiveness • “Depression”, alogia, anergia, mild dementia

  35. Signs of prodromal psychosis • Changes in behavior, thoughts and emotions, with preservation of insight, such as: • Unusual perceptual experiences • “Presence”, shadows, visual trails, ghosts • Imaginary friends • Fleeting apparitions • Odd sounds • Somatic illusions or hallucinations • Heightened or dulled perceptions • Vivid sensory experiences • Sensations and thoughts located outside the body • Frequent distortions or illusions • Brief but frank hallucinations, minimal effect on behavior or thinking

  36. Signs of prodromal psychosis • Changes in behavior, thoughts and emotions, with preservation of insight, such as: • Unusual fears • Marked guardedness, distrustful • Fear of assault (not social phobia) • Avoidance of bodily harm • Somatic delusions • Severe nihilism • Persistent persecutory self-referential thoughts • Paranoia • Extreme guilt, fear of harming others • Bizarre obsessional preoccupations • Fears of mind-reading • Frank delusions, without full conviction

  37. Signs of prodromal psychosis • Changes in behavior, thoughts and emotions, with preservation of insight, such as: • Disorganized or digressive speech and thoughts • Receptive aphasia: “Can’t understand others.” • Expressive aphasia: “Can’t be understood.” • Odd, circumstantial, tangential, paralogical speech • Overly simple speech • Loss of gist of conversation, poor abstracting • Rigid, concrete, almost autistic thinking • Loosening of associations • Marked vagueness, lack of clarity of subjects and objects • Racing speech • Stereotyped ideas, speech • Over-elaborate speech • Poor problem-solving

  38. Signs of prodromal psychosis • 2. Significant deterioration in functioning • Unexplained decrease in work or school performance • Decreased concentration and motivation • Decrease in personal hygiene • Decrease in the ability to cope with life events and stressors • 3. Social withdrawal • Loss of interest in friends, extracurricular sports/hobbies • Increasing sense of disconnection, alienation • Family alienation, resentment, increasing hostility, paranoia

  39. Family-aided Assertive Community Treatment (FACT): Clinical and functional intervention • Rapid, crisis-oriented initiation of treatment • Psychoeducational multifamily groups • Case management using key Assertive Community Treatment methods • Integrated, multidisciplinary team; outreach PRN; rapid response; continuous case review • Supported employment and education • Collaboration with schools, colleges and employers

  40. Family-aided Assertive Community Treatment (FACT): Clinical and functional intervention • Cognitive assessments used in school or job • Low-dose atypical antipsychotic medication • aripiprazole 10-20 mg, quetiapine 300-600 mg, olanzapine 2.5-7.5 mg, risperidone 0.25-3 mg • Mood stabilizers, as indicated by symptoms: • Mood stabilizing drugs: lamotrigine 50-150 mg, valproate 500-1500mg, lithium by blood level • SSRIs, with caution, especially with aripiprazole and/or a family history of manic episodes

  41. Key clinical strategies in family intervention specific to prodromal psychosis • Strengthening relationships and creating an optimal, protective home environment: • Reducing intensity, anxiety and over-involvement • Preventing onset of negativity and criticism • Adjusting expectations and performance demands • Minimizing internal family stressors • Marital stress • Sibling hostility • Conceptual and attributional confusion and disagreement

  42. Key clinical strategies in family intervention specific to prodromal psychosis • Strengthening relationships and creating an optimal, protective home environment: • Buffering external stressors • Academic and employment stress • Social rejection at school or work • Cultural taboos • Entertainment stress • Romantic and sexual complications

  43. Key clinical strategies in family intervention specific to prodromal psychosis • Individualized, responsive education for single families • Little discussion of atrophic aspects of brain functioning emphasis on transient, stress-induced hyperactivity in some brain areas and some biochemical systems • Accelerated recovery, reentry and rehabilitation • Emphasis on careful forward progress. • "Slow down personal and career advancement, until stability and motivation returns."

  44. PIER: Outcomes after one year of treatment Data for 148 at-risk cases from the first 6 years intake: May 7, 2001- September 6, 2007
