Which cognitive skill usually declines first in Alzheimer's patients?

Memory is the cognitive skill that typically declines first in individuals with Alzheimer's disease. Early stages of the disease often manifest as short-term memory loss, where individuals may struggle to remember recent events, conversations, or new information. This initial memory impairment is significant because it severely impacts daily functioning and the ability to live independently.

In Alzheimer's, the early damage in the brain primarily affects areas associated with memory. As the disease progresses, other cognitive skills, such as language, reasoning, and social interactions, may also decline, but memory issues are often the most noticeable early on. This decline in memory can lead to increased confusion and difficulty in carrying out everyday tasks, making it crucial for caregivers to understand this aspect of the disease for appropriate support and intervention.
