Final answer:
The 63-year-old woman showing symptoms such as hoarding behavior, memory loss, difficulty managing finances, irritability, and disorientation is likely to be diagnosed with a form of dementia, which requires a comprehensive medical evaluation and a supportive approach to management.
Step-by-step explanation:
The most likely diagnosis for the 63-year-old woman who has been saving financial documents to the point of creating unsafe living conditions, coupled with lapses in memory, difficulty managing her budget, increased irritability, and disorientation, is a form of dementia. This can include Alzheimer's disease or other cognitive disorders that impact memory, problem-solving abilities, and the execution of daily tasks. The doctor's approach will likely include a thorough review of her medical history, physical exams, lab tests, and brain imaging to rule out other possible causes like a tumor and to assess the extent of cognitive decline.
It is important to treat such conditions with empathy and comprehensive care. Family support is also critical in helping the woman manage her symptoms and improve her quality of life. Professional assistance such as geriatric care management, legal advice for handling the eviction threat, and mental health support should be considered to help with various challenges posed by her condition.
