Pharmacological prevention and treatment of vascular dementia: Approaches and perspectives

摘要

Vascular dementia (VaD) is a common dementing illness. There are no pharmacological agents with a regulatory approval for its treatment or prevention. Review of published clinical trial reports indicates that early treatment of hypertension, a risk factor for stroke, reduces VaD risk and slows progression. However, unlike stroke, treatment of hyperlipidemia with statin class drugs or treatment of blood clotting abnormalities with acetylsalicylic acid do not appear to have an effect on VaD incidence or progression. Pharmacological agents for treatment of Alzheimer's dementia (AD) such as memantine or acetylcholinesterase inhibitors have small positive effects on cognition in VaD, which are likely due to their action on co-existing AD-related neuropathology. Drug development efforts using novel approaches such as patient stratification by their genotype are needed in order to address the increasing need for effective VaD therapeutics.
