What is a progressive or irreversible brain disease that affects mental functions?

Alzheimer's Disease is recognized as a progressive and irreversible brain disease that primarily impacts mental functions such as memory, reasoning, and the ability to perform everyday tasks. It is characterized by gradual cognitive decline, which can begin with mild forgetfulness and progress to severe impairment, affecting one's ability to communicate and interact with others. The disease is the most common cause of dementia in older adults, and it results from the accumulation of amyloid plaques and tau tangles in the brain, leading to the death of brain cells and a decline in cognitive capabilities.

Understanding the nature of Alzheimer’s Disease provides insight into the importance of early diagnosis and intervention, as there are currently no cures, but treatment options can help manage symptoms and improve quality of life for patients and their families over time. By recognizing the disease's progressive nature, caregivers and medical professionals can better prepare and support individuals living with Alzheimer’s.
