Traumatic Brain Injury Induces Cerebrovascular Dysfunction: Consequences For Ischemia And Cerebral Hypoperfusion, Bailey J. Whitehead

Graduate Theses, Dissertations, and Problem Reports

Traumatic brain injury (TBI) is a significant health concern across the United States as well as the broader globe, affecting millions of individuals on an annual basis. While most recover from their TBI and resume their lives normally, some subsets of TBI survivors continue to experience impairments and increased risk for future diseases like cardiovascular disease, stroke, and aging related disease like Alzheimer’s Disease or VCID.

TBI remains a fundamentally difficult neurological injury to pin down mechanistically, due to the variability in severity, timing, and age of patient, among other factors. One significant factor in the pathology has consistently been …

Cerebrovascular Dysfunction And Degeneration In Alzheimer’S Disease Pathophysiology, Dominic Dimitri Quintana

Graduate Theses, Dissertations, and Problem Reports

Alzheimer’s disease (AD) is a terminal illness and the most common form of dementia, which disproportionately affects the aged population. The pathophysiology of AD is characterized by neurodegeneration that slowly progresses, affecting regions of the brain that are involved in learning, memory, language, and executive function. In patients with the disease, early symptoms include non-disruptive forgetfulness that evolves into the inability to form new memories and ultimately the loss of autonomy at late stages. Histopathological hallmarks in the brain from patients with AD is the presence of amyloid-β (Aβ)-plaques and neurofibrillary tangles (NFT) deposited in the parenchyma. Since the discovery …
