Overview
The mainstay of management is symptomatic: treatment of behavioral disturbances, environmental manipulations to support function, and counseling with respect to safety issues. Treatment of behavioral and sleep problems is an important aspect of the care of patients with dementia.[1] A close discussion with the patient's caregiver is essential.[2]
Medical Therapy
The mainstay of management of dementia is :
- Symptomatic
- Treatment of behavioral disturbances
- Environmental manipulations to support function
- Counseling with respect to safety issues.
More precise diagnosis is required for effective management and accurate prognosis. Medical therapy for dementia include:
They increase cholinergic transmission by inhibiting cholinesterase at the synaptic cleft and provide modest symptomatic benefit in some patients with dementia.
Excessive NMDA stimulation can be induced by ischemia and lead to excitotoxicity, suggesting that agents that block pathologic stimulation of NMDA receptors may protect against further damage in patients with vascular dementia.
They have modest benefits in patients with moderate to severe AD[4]
This category includes vitamin E and selegiline [5]
They have modest benefit in delaying functional progression in patients with mild to moderate Alzheimer Disease. High dose Vitamin E is associated with an increase in all-cause mortality and also with heart failure in patients with cardiovascular disease.[6] There is some beneficial effect of selegiline in the treatment of cognitive benefits and in the treatment of behavior and mood in some studies.[5] [7] [8]
