TL;DR: The usefulness of the Japanese version of the Parkinson's disease sleep scale (PDSS-2) that enables the comprehensive assessment of nocturnal disturbances in PD is confirmed.

TL;DR: Barometric pressure change can be one of the exacerbating factors of migraine headaches, and weather change was associated with migraine headache development in 18 patients, 14 of which reported low barometric pressure to be a cause of headache.

TL;DR: RLS comorbidity in migraine patients was associated with insomnia, daytime sleepiness, depressive symptoms, headache-related disability, and increased serum phosphorus levels, which may provide a better understanding of RLS pathogenesis in migraine.

TL;DR: Istradefylline improved daytime sleepiness in PD patients, possibly through its effect on enhancing alertness, and the lack of significant changes in the total PDSS-2 scores over the study period suggests istradefyllines had no negative impact on sleep.

TL;DR: The study revealed that the prevalence of fatigue in Japanese PD patients is as high as that in Western countries, and that fatigue is a relatively independent symptom, although sleep disturbance may be associated with fatigue.
