[Comparative studies of brain CT scan in schizophrenia]

Area of Science:

• Neuroimaging
• Psychiatry
• Radiology

Background:

• Schizophrenia is a complex psychiatric disorder associated with various neurobiological alterations.
• Computed tomography (CT) scans are utilized to investigate structural brain changes in psychiatric conditions.
• Understanding the prevalence and correlates of CT abnormalities in schizophrenia is crucial for etiological research.

Purpose of the Study:

• To compare the incidence of CT scan abnormalities between schizophrenic patients and healthy controls.
• To explore potential associations between CT abnormalities and clinical/demographic factors in schizophrenia, including birth season, family history, and symptom type.

Main Methods:

• A cohort of 48 individuals diagnosed with schizophrenia and 30 healthy volunteers underwent CT scans.
• Statistical analysis was performed to compare the incidence of CT abnormalities between groups and subgroups.

Main Results:

• The incidence of CT abnormalities was significantly higher in the schizophrenic group compared to healthy controls.
• Winter-born schizophrenic patients exhibited a higher rate of CT abnormalities than non-winter-born patients.
• Familial type schizophrenics showed a greater incidence of abnormalities than sporadic type.
• Schizophrenic patients with negative symptoms had a higher rate of abnormalities compared to those with positive symptoms.

Conclusions:

• CT scan abnormalities are more prevalent in individuals with schizophrenia.
• Factors such as winter birth, familial history, and negative symptoms are associated with an increased incidence of CT abnormalities in schizophrenia.
• These findings suggest potential environmental and genetic influences on brain structure in schizophrenia.
