Goal: discussion of the revealing aspects of Parkinson’s disease (PD) by ambulatory neurologists. Techniques: a longitudinal epidemiological survey on applications to a specialized clinic. Results. 603 patients with Parkinsonism suspicions were examined for a four-year period. The syndromal diagnosis of Parkinsonism/extra pyramidal syndrome was correctly recognized by ambulatory neurologists in ca. ¾ of the whole contingent of patients. Hypodiagnostics of PD was the most frequent mistake (71 of 146 corrected diagnoses). Hyperdiagnostics of PD followed by frequency (57 of 146 corrected diagnoses). Every ffth patient applied for consultation caused diffculties in the ambulatory chain. Conclusion. The diagnostic mistakes, no provisional diagnosis for every tenth PD patient cause justifed anxiety in the patients regarding the quality of guaranteed medical aid and force them to apply for specialized consulting reception individually.
