Restless legs syndrome in Parkinson's disease: clinical characteristics and biochemical correlations.

Restless legs syndrome (RLS) is a neurological disorder that responds to dopaminergic drugs, indicating a common pathophysiology with Parkinson's disease (PD).

Depression in Parkinson's disease: study of 60 cases.

Depression is very frequent in Parkinson's disease (PD) and largely unrecognized by neurologists, emphasizing the need of an approach to psychiatric symptoms by non psychiatrists in order to ensure an early diagnosis of depression in PD; clinical characteristics and the prevalence rate of depression in PD were evaluated and the relationship of depression in PD with other variables were determined. Sixty PD subjects, who fulfilled the clinical criteria for primary PD, 56.6% males, age range from 44 to 85 years old, in different stages of the disease were investigated.
