Dementia has numerous causes including the most common, Alzheimer's and Parkinson's disease. Now researchers have discovered with the use of magnetic resonance imaging (MRI) scanning that late-onset dementia is greatly influenced by blood flow to the brain, that is, reduced flow results in brain damage. Lower cerebral blood flow can be due to heart disease or stenosis (narrowing) of cerebral (brain) and carotid (neck) arteries. Dementia is the loss of cognitive functioning and short-term followed by long-term memory loss that result in forgetfulness, a loss of independence, and inability to have normal thought processes.
