Treatments for Schizophrenia
WJEC POTIENTIAL question: Critically consider two (or one) treatments for Schizophrenia
Anti-Depressants
1. Conventional
Blocks the D2 receptors reducing the effect of dopamine. The drug Chlorpromazine can then
reduce positive symptoms.
EVALUATION
Strong evidence to suggest they reduce relapse rates against those on a placbo drug
(DAVIS ET AL 1980)
However...
75% of cases developed irreversible Tardive dyskinesia
Reinforces the fact that they are ill and therefore a self-fulfilling prophecy comes into
effect.
2. Atypical
Allows normal transmission of dopamine however blocks the D2 receptors stopping excess
dopamine entering the post-synaptic. There are lower levels of side effects produced via this as
normal levels are allowed to be transmitted.
EVALUATION
LEUCHT ET AL (1999) found there was only a slight difference between conventional and
atypical
However...
Only 5% taking Atypical anti-depressants found they had Tardive dyskinesia
Fewer side effects
Cognitive Behavioural Therapy

1. CBT Techniques
Clients are told to back track to when the symptoms originated and then to validate any thoughts
they have that seem corrupted.
2. Behavioural activation
Clients are more encouraging to try CBT as there are no drugs involved however they may not be
entirely convinced and think every one deceiving them due to their Schizophrenia. Usually
accompanied with medication to get the best results as they respond more appropriately
