ABSTRACT
The parkinsonian syndromes are a group of disorders with clinical, pathological, and genetic heterogeneity. Although considered to be predominantly motor disorders, other manifestations frequently coexist which, at times, may play a prominent role. More attention is being given to nonmotor aspects of Parkinson’s disease (PD), including cognitive, affective, and sensory disturbances. Autonomic nervous system (ANS) disturbances, although much less prominent in PD than in multiple system atrophy (MSA), may still adversely affect the quality of life of PD patients. Patients with PD often complain of difficulties in micturition and gastrointestinal function and may also have defective cardiovascular control and temperature regulation as well as salivary drooling (1-4). Seborrhea, a classic feature of parkinsonism, is frequently considered a vegetative symptom, although the pathogenesis is obscure (5,6).
