Answer

Drug treatment is primarily used to prevent further worsening of vascular dementia by treating the underlying disease such as hypertension, hyperlipidemia, and diabetes mellitus. Antiplatelet agents are indicated.

Pentoxifylline and, to a more limited extent, ergoloid mesylates (Hydergine), may be useful for increasing cerebral blood flow. In the European Pentoxifylline Multi-Infarct Dementia Study, which is a double-blinded, placebo-controlled, multicenter study, treatment with pentoxifylline was found to be beneficial for patients with multi-infarct dementia. Significant improvement was observed in the scales used for assessing intellectual and cognitive function.

Neuroprotective drugs such as nimodipine, propentofylline, and posatirelin are currently under study and may be useful for vascular dementia. Nicardipine is a dihydropyridine calcium channel blocker that was studied on the treatment of cognitive deterioration of vascular origin. Preliminary studies showed decrease in cognitive deterioration in patients with cerebrovascular disease. [23]

Increasing evidence supports the involvement of the cholinergic system in vascular dementia, similar to that seen in Alzheimer dementia. However, no cholinesterase inhibitors have been approved to date for the treatment of vascular dementia, despite positive results in clinical trials with this medication.
