Abnormalities of brain structure and function in schizophrenia: implications for aetiology and pathophysiology

Area of Science:

• Neuroscience
• Psychiatry
• Genetics

Background:

• Schizophrenia is characterized by brain abnormalities in structure and function.
• Current models implicate frontal and medial temporal lobe structures.
• These abnormalities are observed in patients and some unaffected relatives.

Purpose of the Study:

• To investigate the neuropathological origins of schizophrenia.
• To explore the interplay of genetic and environmental factors in schizophrenia.
• To understand the neurodevelopmental basis of schizophrenia.

Main Methods:

• In vivo imaging studies.
• Post-mortem neuropathology analysis.
• Family and twin studies.

Main Results:

• Abnormalities in brain function and structure are detected in schizophrenia patients.
• Genetic predisposition contributes to neuropathological changes.
• Obstetric complications increase schizophrenia risk and severity in genetically predisposed individuals.

Conclusions:

• Schizophrenia is a brain disease with neuropathological features.
• Neurodevelopmental origins are implicated, involving genetic and adverse in utero obstetric events.
• Interacting genetic and environmental factors shape schizophrenia's neuropathology.
