Final Answer:
Psychosis manifested in the late stages of AD by a. Delusions and hallucinations persist.
Step-by-step explanation:
In the late stages of Alzheimer's disease (AD), psychosis often manifests with the persistence of a. delusions and hallucinations. Alzheimer's disease is a progressive neurodegenerative disorder, and as it advances, it can lead to significant cognitive decline and behavioral changes. Psychosis, characterized by the presence of delusions (false beliefs) and hallucinations (perceptions without external stimuli), becomes more prominent in the later stages of AD.
During this stage, individuals with Alzheimer's may experience a disconnect from reality, leading to the development and persistence of delusions—fixed, false beliefs that are resistant to reasoning or contrary evidence.
Hallucinations, which involve perceiving things that are not present, further contribute to the complexity of the cognitive and behavioral symptoms. These symptoms pose significant challenges for both individuals with Alzheimer's and their caregivers, requiring specialized care and support.
Understanding these manifestations is crucial for caregivers and healthcare professionals in providing appropriate care and interventions for individuals with late-stage Alzheimer's. Strategies often involve a multidisciplinary approach, incorporating medications, behavioral interventions, and support for both the individual and their caregivers to manage the challenges associated with psychosis in advanced Alzheimer's disease.
