What is dementia?

Summary

Dementia is a decline in cognitive abilities, including thinking, memory, and reasoning, that worsens over time. It occurs when brain cells stop functioning properly and can be caused by various types, such as Alzheimer's, frontotemporal, and vascular dementia. The risk increases with age, especially for those over 85. While dementia is not a normal part of aging, research is ongoing to understand why some develop it and others do not. Symptoms include memory loss, confusion, trouble with familiar tasks, and emotional changes. Early diagnosis is crucial for managing the condition and exploring treatment options.
