بررسی آینده نگر 317 بیمار مبتلا به پارکینسون و گزارش آنوسمی در آنها1

In this research we tried to study frequency of clinical manifestations in Parkinson's disease. Hence, a prospective study was conducted in 317 patients who were affected by Parkinson's disease. In a questionnaire we collected data of patient's age, gender and signs and symptoms and then analyzed them. The most common features in our patients were tremor and muscular rigidity. Olfactory dysfunction was observed in 61% of our patients. Dysarthria, stooped posture, fixed facial expression, intellectual deterioration and the on-off response had various frequency among the patients. A new and important point in our research was considerable frequency of Anosmia or Hyposmia in spite of it's low prevalence among the patients of previous studies.
