What is the most common type of dementia?

Alzheimer's disease is the most common type of dementia, accounting for approximately 60-80% of all dementia cases. It is characterized by a progressive decline in cognitive function, affecting memory, reasoning, and the ability to perform daily activities. The pathological features of Alzheimer’s include the accumulation of amyloid plaques and neurofibrillary tangles in the brain, which lead to neuronal loss and synaptic dysfunction.

The onset of Alzheimer's typically occurs in older adults, with risk factors including aging, family history, and certain genetic markers. As the disease progresses, individuals may experience significant changes in behavior and personality, in addition to memory loss, making it a major concern for patients, families, and healthcare providers.

Understanding the prominence of Alzheimer's disease in the context of dementia is essential for recognizing common clinical presentations and developing appropriate management strategies, which include pharmacological treatments aimed at slowing cognitive decline, as well as supportive care for patients and their families.
