Structural brain changes, including atrophy in the midbrain, basal ganglia, and cortical regions such as the frontal and temporal lobes, are observed in advanced stages. Deep brain stimulation (DBS) is an established treatment for motor symptoms in advanced PD, significantly improving motor function and quality of life. However, its effects on brain structure and function remain poorly understood, with conflicting cognitive outcomes and growing interest in potential disease\u2010modifying effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>This review aims to summarize published neuroimaging studies investigating structural and functional brain changes following DBS treatment in PD patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A literature search was conducted to identify neuroimaging studies that examined post\u2010DBS brain changes in PD patients.
