Which cognitive domain is often affected early in Alzheimer's disease?

• A. Attention
• B. Executive functioning
• C. Language
• D. Memory

Answer: (D)

Memory is the cognitive domain that is often affected early in Alzheimer's disease. This is primarily due to the nature of the disease, which significantly impacts brain regions associated with memory formation and retrieval, particularly the hippocampus. Early symptoms of Alzheimer's typically include difficulty in recalling recent events or learning new information, which manifests as short-term memory loss. In the initial stages of the disease, individuals may struggle to remember conversations, misplace items, or forget appointments, which highlights the impairment in their capacity to encode and recall memories. As the disease progresses, other cognitive domains may also become affected; however, memory deficits are among the earliest indicators that can prompt further assessment for Alzheimer’s disease. Understanding this aspect is crucial for recognizing signs of Alzheimer's and facilitating early intervention strategies, which can benefit both the patients and their families.
