title: Cerebrovascular structure and dementia: new drug targets.
abstract: Effective pharmacological treatment of cognitive disorders in dementia is lacking despite extensive efforts to produce active therapy aimed at neuronal and vascular targets. In this review, the evidence for the involvement of vascular mechanisms in the pathology and evolution of dementia will be examined and the potential importance of age-related changes in cerebrovascular structure and cerebral blood flow (CBF) autoregulation will be discussed. With a description of recent clinical results (on statins, angiotensin-converting enzyme inhibitors and Ca(2+) channel blockers) and experimental results (on beta-amyloid), the impact of drugs on cerebrovascular targets is examined. The working hypothesis that targeting vascular mechanisms in dementia is an option for future therapy is proposed.
