Vision Changes with Alzheimer's
Alzheimer’s disease and other forms of dementia lead to a cognitive decline and a decrease in memory.
What is Alzheimer’s disease?
Alzheimer’s disease involves a progressive condition that impairs cognitive functioning, including memory, reasoning, and thinking. It is one form of dementia.
According to the National Institute on Aging, in the United States, roughly 5.5 million people have Alzheimer’s. Most of those affected are over the age of 65.
Other forms of dementia
Alzheimer’s is only one form of dementia. There are also other types, including the following:
Vascular dementia: This form of dementia develops due to damage to the vessels supplying blood to the brain.
Frontal lobe: Frontal lobe dementia occurs due to the breakdown of the nerves in the temporal and frontal lobes of the brain.
Lewy body dementia: Lewy body dementia involves the development of clumps of protein in the brain.
The exact symptoms of dementia may vary based on the form of dementia and the progression of the disease. For instance, at first, symptoms may include problems focusing or learning new things, but as dementia progresses, it can cause problems walking, talking, and doing everyday tasks. Dementia affects personality, judgment, and behavior.
