What does dementia primarily affect?

Dementia primarily affects memory and mental function because it is a cognitive disorder characterized by a decline in cognitive abilities, which includes memory loss, difficulty in reasoning, and problems with language and comprehension. As dementia progresses, individuals may struggle with daily activities and face challenges in communicating and recognizing loved ones, demonstrating significant impairments in thought processes and mental capacity.

While other options like physical strength, hearing ability, and motor skills might be impacted indirectly as dementia progresses, the core symptoms of dementia revolve around cognitive decline, making memory and mental function the central focus of its effects.
