Abstract
Pain is a frequent complaint in Parkinson disease (PD), but also in general elderly population. Its impact on daily life is considered to be high. The McGill Questionnaire (Br-MPQ) is an instrument developed to measure the magnitude of pain impact on life quality. Objective. Measure the pain impact on life of old patients with and without PD. Method. Br-MPQ was applied in a group of PD patients (GI=15) and in age-matched controlled subjects (GII=15). Results. Pain was reported in 53% of GI (n=8) and in 47% of GII (n=7). A small increase of Br-MPQ negative answers about social and daily life activities in GI was observed, but without significant statistical differences in none of Br-MPQ items (p>0.05). Conclusion. In face of recent literature, these data are dissonant, but it is important to note that the sample is small and no generalizations are permitted. It is possible, however, to speculate that other PD major dysfunctions might overcome the pain impact measured by Br-MPQ or, perhaps, this instrument could not be suitable. A possible bias resulted from differences of educational level of the studied subjects and the great difference sex-related between GI and GII should be also considered.
Highlights
Idiopathic Parkinsons disease (PD) ranks second in prevalence of degenerative disease of the nervous system
Pain is not considered to be a prominent feature, it may be a frequent complaint in PD4-7
GI was composed by 15 volunteers with IPD, being 11 men and 4 women, between 53 to 82 years of age (71±7.32 years)
Summary
Idiopathic Parkinsons disease (PD) ranks second in prevalence of degenerative disease of the nervous system. It is estimated that 0.3% of population is affected[1]. A recent Brazilian study carried out in the town of Bambuí, State of Minas Gerais, disclosed that PD affects 3.3% of individuals aged over 65 years[2]. It is considered to be a public health problem in the elderly population[1,2,3]. Pain is not considered to be a prominent feature, it may be a frequent complaint in PD4-7. Variations in pain prevalence in PD have been described in the literature, ranging from 38 to about 50%5,8-10. A minority of patients has such a severe pain which could eventually overshadow other symptoms[10]
