The ego’s ongoing
construction of the world
•Rapid changes between perceptions and
interpretations
•The ego constructs a ”Gestalt”
•This dialectics is abolished in dreaming
and (partly) in psychosis
Psychosis:
•Failure in creating a correct ”Gestalt” of the
outer world
•Regressive creating of meaning
•Inner, private world is given priority
•Meaning is more important than rationality

Stages and subjective experiences in
psychosis:
1: Prodromal phase - days or months
• Withdrawal tendencies – social, working or
study problems
•
•
•
•
•
Affective outbursts
Increased inner speed
Premonition of mental break-down
Compensatory strategies
Depression and panic attacs

2: PSYCHOSIS PHASE:
(weeks - months)
•
•
•
•
•
“Am I in the world or am I the world?”
Regressive strategies to create meaning
Hallucinations confirm delusional thinking
Thoughts and actions controlled by others
Resistance to relying in anyone/anything
from outer world (care, medication, trust
etc)
• Omnipotence and deep loneliness

3: Late psychotic phase:
• Delusions more often questioned and less
•
•
•
•
maintained
“Islands of normality” increasingly frequent
Depressive thoughts more prominent through
reality confrontation
Tendency to seek protection in psychosis
Cooperation with therapist deepening – who can
be trusted?

4: Recovery phase: Remaining
psychotic symptoms or resolution
(most often within 3 months)
•
•
•
•
•
•
•
Separation between inner and outer world
Psychotic “shadows” may remain
Pain, shame - relief
PTSD (traumatic memories from care)?
Denial of psychosis?
Are the bridges burned?
Life with the memory of psychosis and
awareness of one’s vulnerability

From
Disease model (Kraepelin around 1890)
to
Vulnerability-Stress model (Zubin 1977)
or
Vulnerability-Interactional stress model
(Strauss 1983)

Dimensions of vulnerability to psychosis
A: Genetic
B: Pre/perinatal
injuries
C: Early trauma,
Attachment problems

1 factor- low risk
2 factors higher risk
3 factors high risk

Three phases of Schizophrenia (Ciompi)
Biological factors
Phase 1
Psykosocial factors
Early traumatic experiences etc
Genetics, perinatal injuries
Premorbid vulnerability
Stress
Phase 2
Acute psychosis
Psyko-social factors
Phase 3
Some disability or ”chronicity”
Complete remission
or a few symptoms

Long-term schizophrenia
• Around 1/3 of first episode psychosis patients tend to ”chronify”
• Inner world is mixing up with external world
• Deficient control of the ”expected future”
• Deficient awareness of body?
• But often: fantasy, warmth, sense of humour
• Between two fires: overstimulation and understimulation
• Neuroleptic medication 25-40% better than placebo. Risk for overmedication!
• With network and relations, job and supported living, most
patients recover

The schizophrenic person’s personality
change – a dynamic partial explanation
• The early vulnerability also implies a
sensitization of self image – ”outsider”
• The first psychosis is a mental trauma
which further disturbs the self-image
• A partial withdrawal to the inner world
means a higher security of self
• ”Schizophrenia”
jc
13
The affective vulnerability
• A thin ”mental skin”
• Complex and highly charged inner mental
representations of good/bad
• Easily evoked symbolic connections
external/inner world
• Lowered ability to deal with separation,
frustration, falling in love, aggression
• Psychotherapy and low dose medication
jc
14
What is curative?
• Milieu
– low stimulation level, security, coherence
• Medication when needed
– lowest effective dose
• Therapeutic alliance
– respect, interest, non-intrusive warmth
jc

Attitudes towards the patient -according
to the Danish OPUS project:
n A long awaited guest who you want to feel
welcome and at home during a long visit.
n A collaborator, whose insights and attitudes
are decisive for the outcome.
n An individual with personal preferences
that should be taken into account in the
treatment to the greatest extent possible.

Antipsychotic medication – the
patient’s friend or enemy?
• ”Therapeutic window” at 1-4 mg haldol-eqv in f.e.p.
• Higher dose gives side-effects without increasing anti•

psychotic effects
Side-effects appear soon after intake, anti-psychotic
effects after 1-5 days – slow increase of doses!
Antipsychotic effects because of more indifference which
lowers vulnerability to psychotic thoughts? (Healy,
Kapur)
High dose inhibits the dopamine systems of frontal lobes
and thus down-grades the motivational affects
Moderate dose give a chance for psychological
restructuring, high doses lower vitality
The effect is 30-50% betterjc than with no medication 17

”Hearing inner voices”
• When you hear constant inner voices and know
they don’t come ”from outside” - you don’t
suffer from a psychosis but from a disorder of
perception – a minor disturbance of the brain
• Such voices rarely are helped with medication –
still many psychiatrists are tempted to continue
med which may lower your quality of life
• You need psychological support for better
dealing with the voices

Psychological treatments and
psychosis – different models should be
encouraged in the team
• Dynamic models: Identifying relational or
developmental crisis, trauma (separation,
frustration, stress). Important in early phase –
brief and schizophreniform psychoses
• Cognitive models: Taking control over voices,
depressive thinking, investigting delusional
thinking. Important in late phases
• Educational models: How to think about
psychosis, treatments, relapses – all cases
