Tardive dyskinesia and perceptual dysfunction.
Perceptual and Motor Skills
|December 1, 1981
Summary
This study found that chronic schizophrenic patients with tardive dyskinesia exhibit greater central nervous system (CNS) dysfunction, specifically perceptual deficits, compared to those without. This suggests CNS dysfunction may predispose individuals to developing tardive dyskinesia.
Area of Science:
- Neuroscience
- Psychiatry
- Clinical Psychology
Background:
- The link between neuroleptic-induced tardive dyskinesia and central nervous system (CNS) dysfunction remains unclear.
- Tardive dyskinesia is a potential side effect of antipsychotic medications.
Purpose of the Study:
- To investigate the relationship between tardive dyskinesia and CNS dysfunction in chronic schizophrenic patients.
- To determine if patients with tardive dyskinesia show more perceptual dysfunction than those without.
Main Methods:
- Utilized the Bender-Gestalt test to assess perceptual-motor skills.
- Compared a group of chronic schizophrenic patients with tardive dyskinesia to a control group without the condition.
Main Results:
- Patients with tardive dyskinesia demonstrated significantly more perceptual dysfunction on the Bender-Gestalt test.
- The findings support the hypothesis of increased CNS dysfunction in tardive dyskinesia.
Conclusions:
- Central nervous system (CNS) dysfunction may be a predisposing factor for developing neuroleptic-induced tardive dyskinesia.
- Further research is warranted to explore the mechanisms underlying this relationship.
