H.M. is a 67-year-old female, who recently retired from being a school teacher for the last 40 years. Her husband died 2 years ago due to complications of a CVA. Past medical history includes hypertension controlled with Olmesartan 20 mg by mouth once a day. Family history is not contributory. Last annual visits with PCP with normal results. She lives by herself but her children live close to her and usually visit her two or three times a week. Her daughter started noticing that her mother is having problems focusing when talking to her. She is not keeping things at home as she used to, and often she is repeating and asking the same question several times. Yesterday, she had issues remembering her way back home from the grocery store.

Full Answer Section
Risk Factors for Alzheimer's Disease:
- Age: The biggest risk factor is increasing age, especially above 65.
- Family history: Having a close relative with dementia increases risk.
- Genetics: Specific genes like APOE-e4 are associated with higher risk.
- Other medical conditions: Hypertension, diabetes, heart disease, and sleep apnea raise risk.
- Lifestyle factors: Head injuries, low education, smoking, and physical inactivity may contribute.
Types of Dementia:
- Alzheimer's disease: Most common, characterized by progressive memory loss, impaired thinking, and behavioral changes.
- Vascular dementia: Caused by damaged blood vessels in the brain, often with sudden onset and step-wise progression.
- Dementia with Lewy bodies: Includes protein deposits in the brain, leading to cognitive decline, movement issues, and hallucinations.
- Frontotemporal dementia: Affects personality, behavior, and language due to damage to the frontal and temporal lobes.
Similarities and Differences:
- Similarities: All types impair memory, thinking, and daily activities.
- Differences: Symptoms, progression, affected brain areas, and potential causes vary.
Explicit vs. Implicit Memory:
- Explicit memory: Conscious recollection of facts and events (e.g., remembering names, dates, or past experiences).
- Implicit memory: Unconscious learning and skills (e.g., riding a bike, playing an instrument, or learned habits).
Diagnosis of Alzheimer's Disease:
- National Institute on Aging-Alzheimer's Association (NIA-AA) criteria consider:
- Cognitive impairment in multiple domains (e.g., memory, language, reasoning).
- Gradual onset and progressive decline.
- Absence of other brain conditions explaining symptoms.
- Tests may include cognitive assessments, brain imaging, and cerebrospinal fluid analysis.
Therapeutic Approaches for H.M.:
- Pharmacological: Cholinesterase inhibitors like Donepezil may improve some cognitive symptoms in Alzheimer's disease. Antidepressants or antipsychotics might target specific behavioral issues.
- Non-pharmacological: Cognitive stimulation, physical activity, social engagement, and caregiver support can improve quality of life and manage symptoms.
Disclaimer: This information is intended for educational purposes only and does not constitute medical advice. For a diagnosis and tailored treatment plan, H.M. should consult a healthcare professional specializing in dementia or geriatric medicine. They can perform a comprehensive assessment, including considering other potential diagnoses and risk factors, to arrive at an accurate diagnosis and recommend the most suitable therapeutic approach.

H.M.'s Case Study: Exploring Dementia and Potential Approaches
Based on the presented information about H.M., it's crucial to remember that a diagnosis cannot be made without a proper assessment by a qualified healthcare professional. However, considering the symptoms and history, we can explore potential avenues for further investigation and discuss general concepts regarding dementia and related conditions.
