What is the most common form of dementia?

Alzheimer's Disease is recognized as the most common form of dementia, accounting for a significant percentage of all dementia cases. It primarily affects memory, thinking, and behavior, leading to a gradual decline in cognitive function. The condition is characterized by specific changes in the brain, including the accumulation of amyloid plaques and neurofibrillary tangles, which are not seen in other conditions like multiple sclerosis or Parkinson's disease.

Alzheimer's typically begins with mild memory loss and can progress to more severe cognitive impairment, impacting various aspects of daily living. The aging population has contributed to its prevalence, making it a major health concern.

Other choices listed, such as multiple sclerosis and Parkinson's disease, relate to different neurological conditions and may have dementia symptoms in some cases but are not classified as forms of dementia themselves. Cerebral palsy is a movement disorder that does not typically involve cognitive decline, further distinguishing Alzheimer's as the primary form of dementia in medical literature.
