The clinical differentiation between senile dementia of the Alzheimer type and vascular dementia is difficult, and the correlation between clinical and pathological changes is poor. The identification of vascular pathology is important because early management of risk factors may delay onset or reduce the severity of vasculopathy. At present, the diagnosis of cerebral microangiopathy is based on clinical findings, CT and MRI findings. These techniques display the structural consequences of an advanced cerebral microangiopathy. For identification of early stages of small-vessel disease, sophisticated neuroimaging techniques such as positron emission tomography(PET) or single-photon emission computed tomography(SPECT) are required. These methods are expensive, time consuming, and not easily available. Major advantages of neuro-ultrasonographic methods lie in its non-invasive nature and the broad availability of the necessary equipment. Followings are several studies done about neuro-ultrasonographic aids for identification of vascular dementia. Korean Journal of Stroke 2000;2(2): 131~133
