The main pathologic entity involved in the occlusive extracranial cerebrovascular disease is atherosclerosis, which accounts for approximately 90 percent of all cases. Atherogenetic risk factors are the following: hypercholesterolemia, hypertension, immunocomplex, viral infection, and tobacco smoke. The lipid lesions surrounded by a thin capsule tend to rupture easily under the influence of blood flow forces and vibration due to turbulence. Such forms may serve as an explanation for the embolic pathogenetic mechanism of the disease. Brain stroke is one of the major problems in today’s neurology and multiple lacunar strokes developing as a result of microangiopathy, spreading to the corticospinal and corticobulbar tract, are the most common causes of pseudobulbar paresis. Early noninvasive diagnostics of these atherosclerotic changes is indispensable in classification, prevention, prognosis and monitoring of cerebrovascular diseases. Extracranial Duplex Doppler evaluation and Color Doppler Flow Imaging provide direct insight into blood vessel morphology, possible presence of plaques, their composition, size and surface. Relatively recently introduced Transcranial Doppler (TCD) evaluation was a real breakthrough in neurological noninvasive diagnostics. Since patients with the clinical picture of pseudobulbar paresis often need stomatological intervention and have difficulty opening the mouth and walking, it is very important for the stomatologist to be able to recognize these problems and deal with them.
