Use of the noninvasive Doppler Ultrasound examination method for diagnostics of cerebral circulation is very common because it allows quick evaluation; it is cost efficient and easy to use. It represents the imperative in diagnostics, caretaking, monitoring and treatment of patients with different vascular disorders of the brain, as well as in the prospective treatment of patients with a risk of stroke. In this paper described is the use of Transcranial Doppler (TCD) method in the research of cerebral arteries circulation, at the department of neurology in Doboj General Hospital. A total of 114 patients was examined (66 men and 48 women), mean age 61.5 for men and 60.5 years for women. According to the diagnostics of the resident doctors, the frequency structure for neurological disorders was dizziness with or without instability, and the occurrence of tinnitus for 46 patients (40.35%), for 28 patients (24.56%) it was VB insufficiency with or without signs of the brain stem damage, for 20 of them (17.54%) the main symptom was headache, for 12 patients (10.53%) were the stroke symptoms or the consciousness disturbances, while in 8 cases (7.02%) sought answers about the nature of disorder on the basis of TCD examination. Pathology findings was found in 16 patients (11 women and 5 men), out of which four were referred for additional magnetic-resonance testing and MR angiography: three were examined completely with confirmed diagnostics of TCD examination. Presented in this paper is a patient with von Reklinghausen's disease, Arachnoid cysts on both sides and changes on extra and endocrinal brain arteries. Our initial experience with this method of testing the cerebral arteries function proved to be practically usable and very useful in diagnostics, and according to the complexity of the disorder for indicating of the additional diagnostics and determining its treatment.
