Abstract:
Vascular dementia (VaD) constitutes the second most frequent cause of dementia following Alzheimer's disease (AD). In contrast to AD, VaD encompasses a variety of conditions and dementia mechanisms including multiple and strategic infarcts, widespread white matter lesions and hemorrhages. The diagnosis of VaD is based on the patient history, the clinical evaluation and neuroimaging. Treatment of VaD should account for the underlying vascular condition and is directed towards the control of vascular risk factors and stroke prevention. The need for early diagnosis and preventive treatment has promoted the concept of vascular cognitive impairment (VCI). Harmonization standards for the description and study of VCI have recently been published. A common and distinct subtype of VaD is subcortical ischemic vascular dementia (SIVD) which is related to cerebral small vessel disease. SIVD is clinically characterized by impairment of executive functions and processing speed with relatively preserved memory. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a genetic variant of SIVD, represents an important differential diagnosis and may serve as a model of SIVD.
