Final answer:
The question suggests symptoms that may indicate a neurological or cognitive problem, possibly Alzheimer's disease, which includes memory loss, confusion, poor judgment, and behavioral changes. As Alzheimer's disease progresses, patients experience increased deficits in functioning and lose the ability to perform basic activities and control basic bodily functions.
Step-by-step explanation:
The symptoms described in the question such as loss of appetite, new or increased confusion, new or increased incontinence, less ability to perform own Activities of Daily Living (ADL's), and behavior change, are indicative of possible neurological or cognitive issues, which may align with symptoms of Alzheimer's disease. Alzheimer's disease symptoms include disruptive memory loss, confusion about time or place, difficulty with planning and executing tasks, poor judgment, and personality changes.
Increasing damage to the brain from Alzheimer's disease causes deficits in functioning, resulting in symptoms like not recognizing family members, wandering, getting lost, engaging in inappropriate behaviors, agitation, and difficulty carrying out daily activities such as dressing. As the condition progresses to severe stages, patients may lose control over basic functions and become fully dependent on others for care, often leading to death as a result.
