Final answer:
The problem statement in the diagnosis is 'disturbed thought processes', which directly relates to the cognitive impairments observed in Alzheimer's disease. This condition leads to significant memory loss, confusion, and other symptoms that greatly impact daily functioning and quality of life.
Step-by-step explanation:
The part of the diagnosis that is considered the problem statement is 'disturbed thought processes'. This element of the diagnosis identifies the primary issue the patient is experiencing, which is a hallmark symptom of Alzheimer's disease. Assessing Rosa's symptoms in context, the affected areas of the brain may include the hippocampus, which is associated with memory and spatial orientation, as well as other cortical areas responsible for language and problem-solving abilities.
Symptoms of Alzheimer's disease such as disruptive memory loss, confusion about time or place, difficulty with planning and executing tasks, poor judgment, and personality changes relate closely to the problem statement. These symptoms can result from the accumulation of amyloid plaques and neurofibrillary tangles, as well as the overall shrinking in brain volume seen in Alzheimer's patients. While memory lapses can be considered part of normal aging, the severity and persistence of symptoms are what differentiate Alzheimer's disease from normal aging processes.
