Parkinson's disease (PD) is a frequent and complex progressive neurological disorder that increases in incidence with age. Although historically PD has been characterized by the presence of progressive dopaminergic neuronal loss of the substantia nigra, the disease process also involves neurotransmitters other that dopamine and regions of the nervous system outside the basal ganglia. Its clinical presentation in elderly subjects differs from that in younger subjects, with more rapid progression, less frequent tremor, more pronounced axial signs, more frequent non-motor signs linked to concomitant degeneration of non-dopaminergic systems, and more frequent associated lesions. Despite the high prevalence of PD in elderly subjects, few therapeutic trials have been conducted in geriatric patients. Nevertheless, to improve functional disability while ensuring drug tolerance, the principles of optimized and multidisciplinary clinical management have to be known. The aim of this review is to provide an update on clinical and therapeutic features of PD specifically observed in elderly subjects. |
