Alzheimer’s Disease, Senile Dementia, and Parkinson’s: Understanding the Differences

Alzheimer’s Disease:

Definition: Alzheimer’s disease is a progressive neurodegenerative disorder characterized by a decline in cognitive function and memory loss.

Symptoms: Initial symptoms typically include memory loss, difficulty in problem-solving, and confusion, progressing to severe impairment in language, decision-making, and even basic bodily functions.

Pathology: Alzheimer’s is associated with the accumulation of abnormal protein deposits in the brain, namely beta-amyloid plaques and tau tangles, leading to the death of nerve cells and brain tissue shrinkage.

Onset: It usually begins later in life, typically after the age of 65, although early-onset cases can occur.

Senile Dementia:

Definition: Senile dementia is a broad term used to describe cognitive decline associated with aging, where the decline is significant enough to interfere with daily life.

Symptoms: Symptoms include memory loss, impaired judgment, confusion, disorientation, and difficulty in performing familiar tasks.
