Cerebral Hemodynamic Patterns in Mood Disorders and Mild Cognitive Impairment: A Functional Near-Infrared Spectroscopy (fNIRS) Study

Overview

About this study

The purpose of this study is to investigate cerebral hemodynamic patterns using fNIRS across individuals with mood disorders (depression and bipolar disorder) and cognitive disorders (MCI), analyzing variations in cerebral blood flow. Secondary Aim: To explore the correlations between cerebral hemodynamic patterns and symptom severity, as measured by standardized clinical assessments.
