Neurocognitive Disorders Other Than Alzheimer Disease: Vascular Dementia

Brain and nerve = Shinkei kenkyū no shinpo

Abstract

Vascular dementia involves several mechanism of pathogenesis. Cerebral small vessel diseases play a central role in vascular dementia, including sporadic cerebral small vessel diseases, cerebral autosomal-dominant or autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL or CARASIL), cerebral amyloid angiopathy, and amyloid β-related angiitis. Although these diseases have different pathomechanisms, chronic white matter hypoperfusion contributes to development of neuronal dysfunction as a common pathway in vascular dementia. Vascular dementia also may affect the cognitive decline observed in neurodegenerative diseases such as Alzheimer's disease.

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Alzheimer's Disease: Amyloid Beta

Alzheimer's disease is a neurodegenerative disease associated with the accumulation of amyloid plaques in the brain; these plaques are comprised of amyloid beta deposits. Here is the latest research in this field.

Alzheimer's Disease: APP

Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.
