A number of studies have reported lower cigarette consumption in patients with Parkinson’s disease (PD) previous to onset of the disease. In an attempt to determine whether there existed a “pre-morbid attitude” by patients against the use of socially accepted “drugs,” the pre-morbid tobacco, alcohol, and coffee consumption habits were compared in 128 PD patients and 256 controls. Patients and controls were selected by case control method and were recruited from the same health area and socioeconomic stratum. In males, the habits of smoking more than 10 cigarettes/day (p < 0.001) and drinking more than 50 g/day of alcohol (p < 0.001) were significantly less frequent in the PD patients than in the controls, but the differences in coffee consumption were non significant. In females behavior did not differ significantly between the PD group and the controls for any of the three habits. There was no correlation between the amount of smoking and alcohol drinking and age at onset of PD or current Hoehn and Yahr’s staging. Our results suggest the existence of a pre morbid personality in males with PD, possibly conditioning a restrictive attitude toward the consumption of such toxic substances as tobacco and alcohol, yet a more tolerant attitude toward habits more widely accepted socially, like coffee consumption.
