Treatment-resistant
Schizophrenia
• ‘ The presence of poor psychosocial and
community functioning which persists
despite trials of medication that have been
adequate in terms of dose duration and
adherence. ’
– NICE 2002
What is treatment-resistant
schizophrenia?
• A substantial minority of patients show a
poor response to antipsychotics
• Identifiable during the first episode
• More often identified within the first two
years
• Effect on functioning due to positive and
negative symptoms
Clinical characteristics
•
•
•
•
•
Negative symptoms
Neurocognitive function
Depressive features
Substance misuse
Physical illness
Negative symptoms
• Deficit Syndrome - Smaller frontal lobes,
lower frontal metabolism, executive
performance deficits etc.
• Type I/Type II model (Crow 1980)
• Fluctuating nature of symptoms
• Atypicals more effective but mostly in
acute schizophrenia
Neurocognitive function
• Cognitive impairment key predictor of
overall treatment response
• Can appear in the first episode
• Some improvement with atypical
antipsychotics
• However, continues to have lower
cognitive performance than expected
Findings in Neuroimaging
• Structural abnormalities very common
• Literature inconsistent on association
between structural abnormalities and
treatment response
• Progressive brain changes seen
• Differential cerebral blood flow seen in
patients receiving risperidone (Honey et al.
1999)
Demographic variables
• Earlier age of onset associated with poor
outcome (approx.5 years earlier)
• Duration of untreated psychosis (DUP)
• Gender (a robust predictor)
• Poor pre-morbid function
• Neurological soft signs
• Cognitive impairment
Nonresponsiveness and
Intolerance
Treatment Resistance / Non-responsiveness
– ‘ a lack of satisfactory clinical improvement despite the use of
adequate doses of at least two marketed neuroleptics prescribed
for adequate durations.’
Intolerance
– ‘the impossibility to achieve adequate benefit with conventional
neuroleptics drugs because of severe and untreatable neurological
adverse reactions (extra pyramidal symptoms or tardive
dyskinesia)’
- BNF Summary of Product Characteristics
Schizophrenia Epidemiology
•
NICE estimates 210,000 individuals in the UK and Wales (0.4 - 1.4% of
the population) have schizophrenia and are eligible for antipsychotic
treatment
•
63,000 (30%) will be treatment resistant and eligible for treatment with
Clozapine.
•
25,200 (40%) of those who are treatment resistant will not adequately
respond to Clozapine alone.
(NICE 2002)
Management
• Pharmacological treatment
• Psychological and social approaches
• Rehabilitation and Recovery
NICE Meta-analyses –
‘Talking therapies’
CBT
Family interventions
Cognitive remediation
Counselling
Psychoanalytic/psychodynamic
therapy
Psycho education
Social skills training
*
Psychosocial approaches
• CBT
• Cognitive rehabilitation and compensation
strategies
• Family therapy
• Psychosocial programmes
Pharmacological treatment
• High doses of typical antipsychotics seen
to be ineffective in most cases
• Atypical antipsychotics and Clozapine
• Combining antipsychotics
• Adjunctive pharmacological treatments
• Treatment of co-morbid conditions
Maudsley Recommendations
Attempt augmentation if there is no clear benefit after an
adequate trial of Clozapine
Carefully monitor for
– Symptom improvement
– Worsening side effects
– Improvement in side effects
Stop after 3-6 months if not useful
Adjunctive treatments
•
•
•
•
•
Clozapine and Sulpiride
Mood stabilisers
Benzodiazepines
Antidepressants
ECT
Conclusion
• NICE estimates up to 30% of patients with
schizophrenia will be treatment resistant
• Clozapine therapy will fail in 40% of treatment
resistant cases
• If there is an affective component, use
antidepressants or mood stabilisers
• Clozapine augmentation is recommended in partial
response
• 2 alternative anti-psychotics recommended if
Clozapine not tolerated
Working towards recovery
• Psychiatric rehabilitation
• Assertive Community treatment
• Specific interventions (such as for
substance use)
• Community support
• Addressing forensic issues
Rehabilitation
•
•
•
•
•
•
Social learning programmes
Enhancing skills
Cognitive remediation
Modifying environments
Compensating for deficits
Family psycho-education
