Evaluation of Pineal Gland in Patients with Schizophrenia

Recent advancements in neuroimaging techniques have facilitated the identification of numerous structural brain alterations associated with schizophrenia, potentially serving as valuable biomarkers. This study aimed to explore the volumetric changes in the pineal gland correlated with schizophrenia symptoms, employing standard brain segmentation methodologies. The study encompassed 135 participants, comprising 82 controls and 53 patients, all of whom provided voluntary consent. Magnetic resonance imaging (MRI) of the brain was conducted using the magnetization prepared rapid acquisition protocol, and the acquired images were processed through BrainSuite software. Statistical analysis was done to determine the significance of volumetric differences in the pineal gland between patients and controls. In addition, it assessed any correlations with demographic variables, such as age and sex. The control group’s mean age was 29.28 ± 6.03, while the patient group was 31.32 ± 6.44. No significant differences were observed between the groups in terms of sex or age distribution, with P = 0.583 and 0.064, respectively. The average pineal gland volume in patients with schizophrenia was 48.82 ± 20.39 cm3, markedly lower than the 64.23 ± 26.51 cm3 observed in controls. The findings indicate that individuals with schizophrenia possess smaller pineal glands compared to the general population. It is concluded that MRI is a viable tool for assessing structural brain changes linked to schizophrenia, and the pineal gland may play a contributory role in the disease’s pathogenesis.
