Long Term Care Certification Practice Test

The option highlighting the inability to focus or follow simple directions is less characteristic of Alzheimer's disease compared to the other symptoms listed. While individuals with Alzheimer's may experience difficulties with attention as the disease progresses, the hallmark symptoms typically include memory-related challenges.

Alzheimer's disease primarily affects memory, particularly short-term memory. This is reflected in the first choice, where a person struggles to remember names and faces, which is a common early sign. Additionally, significant memory loss, as mentioned in the third option, is a defining symptom of the disease, indicating a more advanced stage of cognitive decline.

The fourth choice regarding changes in mood and personality is also a recognized aspect of Alzheimer's disease. Individuals may become more irritable, anxious, or exhibit personality shifts due to the cognitive changes they are experiencing.

In summary, while attention and focus can be impacted in individuals with Alzheimer's, the specific inability to follow simple directions is not as directly associated with the disease's typical symptomatology compared to memory loss and personality changes.
