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.”

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.
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.

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.

disorders?
Probably
“Yes, we can?”

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
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:

Signs of prodromal psychosis
Schedule 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
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
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

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
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
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 5001500mg, lithium by blood level
• SSRIs, with caution, especially with aripiprazole and/or a family
history of manic episodes
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
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
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."

*Savings from avoided initial hospitalizations in Portland. Cost estimates based on incidence rate differences (i.e., resulting fewer cases) between
greater Portland and the other 3 Maine urban areas. Amounts are based on time period—2002, 2007 or the average for 2001-2007—days in
hospital for first admission and daily rate in dollars. Population based on US Census estimates for the respective years.
Differences between treated prodromal
and post-psychotic states
Prodromal young persons have manifested:
• Maintenance of insight (prevention of loss)
• Continued ego-dystonic response to psychotic symptoms
• High acceptance of, and adherence to, treatment
• Low rates of substance abuse
• More open to discontinuing heavy drug and alcohol abuse
• Less resistance to family inclusion by patient
• Higher motivation to continue schooling and/or work
• More trusting and grateful therapeutic relationships
• Higher sensitivity to treatments
• Higher likelihood of improving course of functioning
Conclusions
• Public education is influencing attitudes, knowledge and behavior.
• Accurate referrals are coming from outside the mental health system.
• Treatment is blocking the final common pathway to psychosis.
• Medication at low doses is adequate but appears essential for
prevention of imminent, and perhaps later, psychosis.
• Very low conversion rates and functional improvement accompany
comprehensive treatment (~15%; ~5% for schizophrenic disorders).
• A substantial proportion of the incident population can be identified
and prevented from developing psychosis.
