Study Notes
Alzheimer's Disease
Treatment
-
Medications:
- Cholinesterase inhibitors (e.g., donepezil) to improve memory and cognitive function
- Memantine to manage symptoms of moderate to severe Alzheimer's
- Combination therapy with both types of medications
-
Non-pharmacological interventions:
- Cognitive training and rehabilitation
- Behavior management
- Caregiver support and education
-
Lifestyle changes:
- Regular exercise and physical activity
- Social engagement and intellectual stimulation
- Healthy diet and sleep habits
Diagnosis
-
Clinical evaluation:
- Medical history and physical examination
- Neuropsychological tests (e.g., MMSE, MoCA) to assess cognitive function
- Laboratory tests (e.g., blood work, imaging) to rule out other conditions
-
Diagnostic criteria:
- National Institute on Aging-Alzheimer's Association (NIA-AA) criteria
- Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria
-
Biomarkers:
- Amyloid-β and tau protein in cerebrospinal fluid (CSF)
- Positron emission tomography (PET) scans for amyloid-β deposition
Causes
-
Risk factors:
- Age (increased risk with age, especially after 65)
- Family history and genetics
- Lifestyle factors (e.g., physical inactivity, social isolation)
-
Pathophysiology:
- Amyloid-β protein accumulation and neurofibrillary tangles
- Neuroinflammation and oxidative stress
- Disruption of neuronal communication and synaptic function
-
Genetic factors:
- Early-onset Alzheimer's: mutations in APP, PS1, and PS2 genes
- Late-onset Alzheimer's: multiple genetic variants, including APOE ε4 allele
Alzheimer's Disease
Treatment
- Cholinesterase inhibitors, such as donepezil, are used to improve memory and cognitive function
- Memantine is used to manage symptoms of moderate to severe Alzheimer's
- Combination therapy with both cholinesterase inhibitors and memantine is also an option
- Cognitive training and rehabilitation are non-pharmacological interventions that can help
- Behavior management and caregiver support and education are also important non-pharmacological interventions
- Regular exercise, social engagement, intellectual stimulation, a healthy diet, and good sleep habits are recommended lifestyle changes
Diagnosis
- A clinical evaluation, including a medical history and physical examination, is used to diagnose Alzheimer's
- Neuropsychological tests, such as the MMSE and MoCA, are used to assess cognitive function
- Laboratory tests, including blood work and imaging, are used to rule out other conditions
- The National Institute on Aging-Alzheimer's Association (NIA-AA) and Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria are used to diagnose Alzheimer's
- Biomarkers, such as amyloid-β and tau protein in cerebrospinal fluid (CSF) and positron emission tomography (PET) scans, can be used to support a diagnosis
Causes
- Age is a significant risk factor, with risk increasing after 65
- Family history and genetics play a role, with certain genetic mutations and variants increasing risk
- Lifestyle factors, such as physical inactivity and social isolation, also contribute to risk
- Amyloid-β protein accumulation and neurofibrillary tangles are key pathological features of Alzheimer's
- Neuroinflammation and oxidative stress are also thought to contribute to the disease
- Disruption of neuronal communication and synaptic function is a hallmark of Alzheimer's
- Early-onset Alzheimer's is often caused by mutations in the APP, PS1, and PS2 genes
- Late-onset Alzheimer's is associated with multiple genetic variants, including the APOE ε4 allele
