What is the primary symptom of Alzheimer Dementia?

The primary symptom of Alzheimer's dementia is a progressive loss of short-term memory. This condition typically manifests as difficulties in remembering recent events, conversations, or new information, which can significantly impact daily functioning and independent living. Individuals with Alzheimer's often find it increasingly challenging to retain new memories, leading to confusion and disorientation as the disease progresses.

Short-term memory loss is often one of the first signs that prompts individuals or their families to seek medical evaluation. As the disease advances, long-term memory may also be affected, but in the early stages, the most notable symptom tends to be this loss of short-term memory. This differentiates Alzheimer's from other forms of cognitive impairment where memory functions may not be as severely impacted initially.
