  • Title: Morphometric Study of the Intracranial Fluid Spaces in Schizophrenia.
    Author: Ozdikici M.
    Journal: Neurol India; 2024 Jul 01; 72(4):817-823. PubMed ID: 39216040.
    Abstract:
    BACKGROUND: The intracranial fluid spaces (IFS), also known as "the extra-axial spaces," consist of the superficial cerebral sulci, the Sylvian fissures, the basal cisterns, the third ventricle, the fourth ventricle, and the two lateral ventricles. In diseases such as schizophrenia, Alzheimer's, Parkinson's, and especially hydrocephalus, IFS' enlargements are observed. OBJECTIVE: Our study aimed to determine the mean values of IFS measurements in patients with schizophrenia and compare them with healthy controls. MATERIAL AND METHODS: This work has been carried out on 188 cases, out of which 88 schizophrenia patients (56 men and 32 women) met the diagnostic criteria according to DSM-5 for schizophrenia and 100 healthy controls (50 men and 50 women). The 10 parameters have been used to evaluate IFS on magnetic resonance imaging (MRI) scans. RESULTS: The parameters showing statistically significant differences were higher in favor of the individual with schizophrenia. Except for the bifrontal index and Evan's index, most parameters (the bicaudate index, the fourth ventricle width, the fourth ventricle index, the maximum width of the anterior interhemispheric fissure, the maximum width of the right frontal subarachnoid space, the maximum width of the left frontal subarachnoid space, the maximum width of the right Sylvian fissure, and the maximum width of the left Sylvian fissure) were obtained statistically highly significant differences between the examined and control groups. CONCLUSIONS: In schizophrenia, it is more practical to evaluate brain atrophy using some parameters, especially the width of the Sylvian fissure and the bicaudate index.
