Here are the answers to Question One:

1. List 3 important differential diagnoses for Mr. Bwalya (6 marks)

• Alzheimer's Disease
• Vascular Dementia
• Frontotemporal Dementia

2. Explain the differential diagnoses above in 1. (6 marks)

• Alzheimer's Disease: This is a progressive neurodegenerative disorder characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain, leading to widespread brain atrophy. It typically presents with insidious onset of memory impairment, followed by decline in other cognitive domains and behavioral changes.
• Vascular Dementia: This type of dementia is caused by brain damage resulting from impaired blood flow to the brain, often due to strokes or chronic small vessel disease. It can present with a step-wise decline in cognitive function, focal neurological deficits, and may include executive dysfunction and behavioral changes.
• Frontotemporal Dementia: This is a group of disorders characterized by progressive neuronal loss predominantly in the frontal and temporal lobes. It often presents with early and prominent changes in personality, behavior (e.g., disinhibition, apathy, irritability), or language difficulties, rather than primary memory impairment.

3. What do you think is the definitive diagnosis of Mr. Bwalya's condition? (2 marks)
The definitive diagnosis is Alzheimer's Disease.

4. What line of management would you arrange for him? (6 marks)

1. Pharmacological Management: Initiate cholinesterase inhibitors (e.g., donepezil, rivastigmine) to help manage cognitive symptoms. If the disease progresses to moderate or severe stages, memantine may be considered.
2. Non-pharmacological Interventions: Implement cognitive stimulation therapy, provide a structured and safe environment, and offer behavioral interventions to manage agitation, irritability, and other behavioral problems.
3. Caregiver Support and Education: Provide comprehensive education and support to the family and caregivers on how to manage the patient's symptoms, ensure safety, and cope with the progression of the disease.
4. Symptomatic Treatment: Address specific symptoms such as the "fit" (seizure) with appropriate anticonvulsant medication if recurrent, and manage behavioral and psychological symptoms of dementia (BPSD) with non-pharmacological approaches first, and then cautiously with antipsychotics or antidepressants if necessary.
