Neuroangiogenesis: A Vascular Basis For Alzheimer's Disease And Cognitive Decline During Aging, Charles T. Ambrose Jan 2012

Neuroangiogenesis: A Vascular Basis For Alzheimer's Disease And Cognitive Decline During Aging, Charles T. Ambrose

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Angiogenesis directs development of the brain's microcirculation during antenatal and postnatal development, but its role later in life is less well recognized. I contend that during senescence a reduced cerebral capillary density accounts in part for the vascular cognitive impairment observed in many older persons and possibly for some forms of Alzheimer's disease. I propose that neuroangiogenesis is essential throughout adult life for maintaining the microcirculation of the cerebral cortex and elsewhere in the brain and that it commonly declines with old age. To support this hypothesis I have examined the neurological literature for relevant studies on cerebral capillary density …
