Abstract Gliomas are primary brain tumors that can cause neuropsychiatric symptoms, including severe depressive symptoms (SDS; in 14%) and an absence of (ADS; 29%), determined by Center for Epidemiologic Studies Depression (CES-D) scores. We examined the association between both SDS ADS tumor location 201 patients with diffuse glioma before surgery. Tumors white matter disconnectomes did not relate to CES-D using sparse canonical correlation analysis. were associated right corticospinal tract, fornix, inferior fronto-occipital fasciculus left uncinate fasciculus, whereas was first segment superior longitudinal temporal cingulum thalamus Bayesian regression analyses. occurs even more frequently than does SDS, which is explained partly location. This research aids understanding gliomas mood dysfunction general.

Vascular cognitive impairment is common after stroke, in memory clinics, medicine for the elderly services, and undiagnosed community. disease said to be second most cause of dementia Alzheimer disease, yet vascular dysfunction now known predate decline dementias at older ages are mixed. Neuroimaging has a major role identifying proportion versus other likely pathologies patients with impairment. Here, we aim provide pragmatic but evidence-based summary current state potential imaging biomarkers, focusing on magnetic resonance computed tomography, which relevant diagnosing, estimating prognosis, monitoring impairment, incorporating our own experiences. We focus markers that well-established, profile association measures, also consider more recently described, including quantitative tissue injury. highlight gaps accessibility translation routine clinical practice.
