Study Notes
Dementia Overview
- Dementia is a heterogeneous syndrome causing impairment in at least one cognitive domain, severely limiting daily functioning.
- Common etiologies of dementia in developed nations include Alzheimer's disease, vascular dementia, mixed dementia, Lewy body dementia, and frontotemporal dementia.
Standardized Evaluation Tools
- Bristol Activities of Daily Living Scale
- Barthel Index
- Functional Independence Measure
Alzheimer's Disease Pathophysiology
- In Alzheimer's disease, there is a decrease in acetylcholine, a critical neurotransmitter.
- Acetylcholine impacts neuronal excitability, synaptic transmission, synaptic plasticity, and neuron group firing coordination.
Cholinesterase Inhibitors
- Cholinesterase inhibitors reversibly bind to cholinesterase, inhibiting acetylcholine degradation in synaptic clefts, enhancing cholinergic transmission.
- Commonly prescribed cholinesterase inhibitors:
- Donepezil (Aricept)
- Galantamine (Razadyne)
- Rivastigmine (Exelon)
- Recommended dosages:
- Donepezil: 5 to 10 mg per day
- Galantamine: at least 16 mg per day
- Rivastigmine: 6 to 12 mg per day orally or 9.5 mg per day transdermally
Memantine Mechanism
- Memantine acts as a partial NMDA receptor antagonist, limiting glutamatergic excitation and protecting cortical and hippocampal neurons.
Combination Therapy and Supplements
- Combination therapy of cholinesterase inhibitors and memantine is recommended for patients with moderate to severe dementia.
- Vitamin E (alpha-tocopherol) may have protective properties; a dosage of 2,000 IU per day is reasonable for mild to moderate Alzheimer's patients, especially alongside cholinesterase inhibitors.
Ineffective Treatments
- Statins, Ginkgo Biloba, NSAIDs, and Omega-3 fatty acids have been shown to be ineffective for Alzheimer's treatment.
Non-Pharmacologic Therapies
- Recommendations for cognitive and functional symptoms include:
- Exercise: Benefits include improved physical function and reduced neuropsychiatric symptoms, though cognitive function may not improve.
- Mental stimulation programs and enjoyable leisure activities
- Occupational therapy
Treatment Recommendations by Severity
- For mild to moderate Alzheimer's: Cholinesterase inhibitors indicated.
- For moderate to severe Alzheimer's: Memantine indicated.
- Non-pharmacologic therapy for mild to severe Alzheimer's: Structured physical exercise programs.
- Non-pharmacologic therapy for mild to moderate Alzheimer's: Mental stimulation, enjoyable leisure activities, and occupational therapy.
