1.0 INTRODUCTION
This essay compares and contrasts psychological and biological explanations of schizophrenia. This will be done via a point by point comparison of both psychological and biological explanations of schizophrenia at the same time, while first pointing out similarities in their explanation of psychotic symptoms and thereafter any differences.
2.0 What is schizophrenia?
Schizophrenia refers to a mental disorder characterized by a breakdown in cognitive functioning and processes responsible for normal thought, emotions and ways of behaving. The result of this psychotic breakdown is faulty perception, hallucinations, inappropriate behaviour and delusions. Grand delusion is perhaps one of the more common or reported symptoms of schizophrenics with delusions of persecution or grandeur. According to Maher (2001), at least 75% of schizophrenics experience symptomatic delusions of some sort.
