Elucidation Of The Mechanisms By Which Anesthetics Induce Blood-Brain Barrier Breakdown And Delirium In The Elderly, George A. Godsey Ii
Elucidation Of The Mechanisms By Which Anesthetics Induce Blood-Brain Barrier Breakdown And Delirium In The Elderly, George A. Godsey Ii

Delirium is a highly prevalent neuropsychiatric or neurocognitive disorder that presents a major problem to modern healthcare. Patients suffering from delirium normally have a worse prognosis, prolonged hospital stay, increased hospital cost, long-term cognitive impairment, and higher mortality rates. Many factors can predispose one to develop delirium, which makes treating this disorder a daunting task. Unfortunately, delirium is the most common psychiatric syndrome found in the hospital setting. In fact, a form of delirium known as postoperative delirium (POD) is one of the most common postoperative complications faced by elderly patients undergoing surgery.
POD is a major problem in modern …

Brain homeostasis can be affected in a number of ways that lead to gross anatomical, cellular, and molecular disturbances giving rise to diseases like Alzheimer’s disease (AD) and related dementias. Unfortunately, the mechanistic pathoetiology of AD’s hallmark features of cerebral amyloid plaque buildup and neuronal death are still disputed. Using human brain AD sections, immunohistochemistry experiments revealed internalized surface proteins, co-localized to an expanded lysosomal compartment. Other stains for amyloid-β1-42 (Aβ42) and various immunoglobulin (Ig) species displayed them leaking out of the cerebrovasculature through a dysfunctional blood-brain barrier (BBB), binding to neurons in the vicinity, and localizing to intracellular vesicles …

Diabetes Mellitus And Hypercholesterolemia Are Risk Factors For Alzheimer’S Disease And Appear To Affect The Integrity Of The Blood Brain Barrier, Jacqueline Dash
Graduate School of Biomedical Sciences Theses and Dissertations
Studies have shown that the vascular risk factors common to diabetes mellitus and hypercholesterolemia are also risk factors for Alzheimer’s disease (AD). It is currently unknown how these diseases are associated with AD, but they may cause a leak in the blood brain barrier (BBB), which is one of the hallmarks of AD. In this preliminary study, over 150 pig brain slides were tested for the expression levels of tight junction proteins occludin and claudin V in the BBB microvasculature. There were three groups of pig brains used in this study namely, control pigs, pigs with diabetes mellitus and hypercholesterolemia …
