The association between sleep disturbances and tooth loss among post-stroke patients.

Background: Loss of teeth has been associated with neurological and sleep disorders. It is considered to be a predictor of stroke and leads to modifications of airway patency and predisposition to obstructive sleep apnea.

Objective: To investigate sleep quality, risk of obstructive sleep apnea and excessive sleepiness among post-stroke patients with tooth loss attending the Neurovascular Clinic of the Federal University of São Paulo.

Circadian preference and stroke characteristics: A descriptive study.

There is evidence that circadian misalignment is linked with an increased risk of stroke and that circadian preference is linked with rehabilitation outcomes after stroke. Circadian preferences refer to preferences based on individuals' characteristics in respect of the timing of physiological functions that are typically assessed by self-report questionnaires. This study set out to explore this relationship by examining whether there was an association between circadian preference and stroke characteristics in a sample of stroke outpatients, considering the time of stroke onset, the topography of the stroke and the resulting disability.
