Symptoms and duration of the prodromal phase in parkinson's disease

Abstract: To investigate the duration of a prodromal phase before the onset of the classic symptoms of idiopathic Parkinson's disease, the authors conducted a retrospective case-control study of 60 patients with Parkinson's disease and 58 age- and sex-matched control subjects, covering the decade preceding the onset of classic Parkinson's disease. The symptoms were derived from files of the patients' general practitioners. Compared with control subjects, patients pre-Parkinson's disease had more central nervous system, … Show more

Lay-Son et al diagnóstica, en contraste con la resolución más expedita de la interconsulta proveniente desde la AS.…”

“…This finding highlights the close and enigmatic relationship between depression and PD. Not only does PD increase the risk for depression, but as Nilsson and colleagues have shown in a previous paper (11), depression is in fact a risk factor for PD, and may be the presenting symptom in some PD cases (12). Thus, a common neurobiological factor may underlie both depression and PD, or depression may damage dopaminergic nigrostriatal neurons through yet unknown mechanisms.…”
