Non-motor symptoms fluctuations in patients with Parkinson's disease at the Clinical Hospital of Salvador, Bahia.

This study showed that, in the study population, approximately half of the patients had NMS fluctuations, with a higher frequency among women. A higher frequency was present in patients with earlier age of diagnosis, longer duration, and greater severity of disease. These findings point to the importance of recognizing the fluctuations of NMS in the study population, since these may not be spontaneously mentioned by the patient, who is remaining unnoticed, undiagnosed, and not treated by the neurologist, representing a significant aggravating factor in the patient's quality of life.
