Understanding the types of Dementia: By Amanda Williams, DO
April 1, 2015
According the Alzheimer’s Association, “dementia is a general term for a decline in mental ability severe enough to interfere with daily life.”
Dementia develops when the parts of the brain that are
involved with learning, memory, decision-making, and language are affected by
infections and/or diseases. Alzheimer’s is the most common form of dementia. It
accounts for 60-80% of all cases of dementia, according to the Alzheimer’s
Association. Alzheimer’s causes brain cells to die. Symptoms begin slowly and
steadily become worse. As the disease progresses, symptoms range from slight
forgetfulness to significant impairments in judgment, thinking, and the ability
to perform daily activities. Ultimately, individuals may require total care.
Vascular Dementia is the second most common cause of dementia. It’s caused by lack of blood flow to the brain. Vascular dementia can happen as you age and/or after a stroke. The location and severity of the stroke(s) determine the symptoms and seriousness of the symptoms that arise. Symptoms typically begin abruptly and progress in a step-wise fashion with repeated strokes. At this time, there is no way to reverse damage that has already been caused by a stroke. However, treatment to prevent further strokes is very important.
