Sažetak
Purpose: So far there is no reliable test that can clearly distinguish between various movement disorders and the diagnosis is still based on the clinical examination. However, the misdiagnosis rates for the most common movement disorders ; Parkinson’s disease (PD) and Essential tremor (ET) in the early stages is as high as 20–30% for PD and in about one of three patients in ET. We initiated this study is to asses the possibility of Transcranial sonography (TCS) to help differentiate PD from ET by measuring echogenicity of the substantia nigra (SN). Material & Methods: Our study included 60 patients with PD, 30 patients with ET and 60 healthy controls. The TCS recordings were done in axial plane by standardized protocol by two independent investigators. SN was displayed, encircled, and measured two times. Results: Patients with ETand PD had mean SN size of 0.15cm 2 (60.04) and 0.27 cm 2 (60.06), which showed significant difference (p , 0.001). In the control group bilateral combined mean SN size was 0.17cm 2 (60.06), which was significantly different from PD group (p , 0.001), but not from ET group (p 5 0.240). Conclusion: The measurement of SN by means of TCS is a valuable tool in the differentiation of movement disorders. Due to portability, lack of invasiveness and easiness of reproducibility, TCS might help in diagnosing PD or in differential diagnosis of doubtful clinical cases.
