What is a characteristic symptom of Stage 4 Alzheimer's disease?

In Stage 4 Alzheimer's disease, individuals experience significant cognitive decline, making it challenging for them to engage in everyday tasks and often requiring them to receive maximum assistance with daily activities. The characteristic symptoms of this stage include impaired ability to recall recent events, diminished problem-solving skills, and confusion regarding personal history or current situations.

While forgetfulness of recent events can be a symptom in earlier stages, in Stage 4, the memory issues become more pronounced and greatly impact the individual's ability to function independently. This decline progresses to the point where the individual often requires extensive support and supervision. Therefore, the need for maximum assistance aligns closely with the difficulties individuals face in managing their daily lives due to the severity of the cognitive degradation at this advanced stage.
