What are common psychiatric symptoms in advanced stages of Alzheimer's disease?

Psychiatric symptoms commonly observed in the advanced stages of Alzheimer's disease include depression, anxiety, and psychosis. As the disease progresses, individuals may experience significant emotional and psychological changes.

Depression is prevalent due to the awareness of cognitive decline and the loss of independence, which can lead to feelings of sadness or hopelessness. Anxiety can manifest as a response to confusion and heightened stress related to everyday situations. Psychosis may appear as hallucinations or delusions, where the individual may misinterpret reality due to the altered brain functions associated with Alzheimer's.

Other choices present symptoms that are either less specific to Alzheimer's or may not accurately reflect the psychiatric profile seen in advanced stages. Memory loss, confusion, and mood swings are also significant but are more representative of cognitive symptoms rather than purely psychiatric symptoms. The inclusion of fatigue, withdrawal, and excessive cheerfulness does not align with the characteristic psychiatric symptoms seen in advanced Alzheimer's, as these emotions and behaviors are not typically associated with the disorder during its advanced progression.
