Diminished Glymphatic Transport and Lymphatic Drainage Tied to Cerebral Amyloid Angiopathy

Author: Vignesh Subramanian, Class of 2024 Cerebral amyloid angiopathy (CAA) is a cerebrovascular disorder characterized by the accumulation of amyloid protein deposits along cortical capillaries, cerebral vessel walls, and the brain’s leptomeninges. These plaques weaken fragile blood vessels, often resulting in intracerebral hemorrhaging. CAA is linked to vascular cognitive impairment and dysfunction and is a major contributor to the pathogenesis of Alzheimer’s disease (AD) and … Continue reading Diminished Glymphatic Transport and Lymphatic Drainage Tied to Cerebral Amyloid Angiopathy

Cranial Windows Enable Transcranial Ultrasound Imaging of CSF Disorders

Vignesh Subramanian ’24 Figure 1: A CT scan of a human brain with hydrocephalus, made visible by the enlarged ventricles. Hydrocephalus is a neurological disorder characterized by the abnormal accumulation of cerebrospinal fluid (CSF), the plasma fluid in which the brain is suspended and cushioned, in cavities of the brain known as ventricles. CSF disorders like hydrocephalus develop when CSF is either excessively produced or … Continue reading Cranial Windows Enable Transcranial Ultrasound Imaging of CSF Disorders

MRI Brain Mapping of Glymphatic System May Inform AD Diagnostic

Vignesh Subramanian ’24 Alzheimer’s disease (AD) is a neurodegenerative disorder and form of dementia that causes progressive loss of memory, critical thinking skills, and behavioral capabilities. Among other pathophysiological mechanisms, the disease is characterized by disruptions in the glymphatic system, which is responsible for the facilitation of cerebrospinal fluid (CSF) and interstitial fluid (ISF) exchange driving macroscopic waste and solute clearance. Breakdowns in this clearance … Continue reading MRI Brain Mapping of Glymphatic System May Inform AD Diagnostic
