Data from 30 elderly inpatients with major depression were analyzed to explore the relationship between subcortical hyperintensities (SH) on MRI and activities of daily living (ADLs). A comparison of subjects based on a median split of the severity of SH revealed that subjects with greater SH performed worse on both instrumental and physical ADLs. A hierarchical multiple regression revealed that age, depression severity, neuropsychological test performance, and SH variables accounted for a total of 53% of the variance in ADL functioning. Severity of SH accounted for an additional 18% of the variance over and above the other three variables. Results suggest that severity of subcortical disease measured by MRI improves prediction of functional impairment in elderly individuals.

Background: Cardiovascular risk factors (CRFs) like hypertension, high cholesterol, and diabetes mellitus are increasingly linked to cognitive decline and dementia, especially in cerebral small vessel disease (cSVD). White matter hyperintensities (WMH) are closely associated with cognitive impairment, but the mechanisms behind their development remain unclear. Blood-brain barrier (BBB) dysfunction may be a key factor, particularly in cSVD.

Background: White matter (WM) is a principal component of the human brain, forming the structural basis for neural transmission between cortico-cortical and subcortical structures. The impairment of WM integrity is closely associated with the aging process, manifesting as the reorganization of brain networks based on graph theoretical analysis of complex networks and increased volume of white matter hyperintensities (WMHs) in imaging studies.
Methods: This study investigated changes in the robustness of WM brain networks during aging and assessed their correlation with WMHs.

CSF1R-related leukoencephalopathy (CSF1R-L) and AARS2-related leukoencephalopathy (AARS2-L) were two disease entities sharing similar phenotype and even pathological changes. Although clinically, radiologically, and pathologically similar, they were caused by mutation of two different genes. As the rarity of the two diseases, the differential diagnosis of them was difficult.

Purpose: Fluid exchanges between perivascular spaces (PVS) and interstitium may contribute to the pathophysiology of small vessel disease (SVD). We aimed to analyze water diffusivity measures and their relationship with PVS and other SVD imaging markers.
Methods: We enrolled 50 consecutive patients with a recent small subcortical infarct.

Encephalitis due to Epstein-Barr Virus (EBV) is a rare condition that primarily affects children and immunosuppressed patients. Diagnosing EBV encephalitis can be challenging due to its nonspecific clinical presentation and the lack of confirmatory tests. We present the case of a 66-year-old woman with a history of kidney transplantation who was admitted due to progressive subacute mental deterioration, preceded by vertigo and without fever.
