Droxidopa for neurogenic orthostatic hypotension: a randomized, placebo-controlled, phase 3 trial.
To determine whether droxidopa, an oral norepinephrine precursor, improves symptomatic neurogenic orthostatic hypotension (nOH). ⋯ This study provides Class I evidence that in patients with symptomatic nOH who respond to open-label droxidopa, droxidopa improves subjective and objective manifestation of nOH at 7 days.

Prevalence of fatigue in Parkinson disease and its clinical correlates.
To assess in a noninterventional setting the prevalence and severity of fatigue in patients with Parkinson disease (PD). ⋯ Approximately one-third of patients with PD have distressing fatigue, which is significantly associated with depression and sleep disorders. The fact that the presence of fatigue worsens patient quality of life supports the need to better diagnose and treat this debilitating symptom.
