Consequences of Post Stroke Polysomnographic Abnormalities on Functionnal Recovery and Survival After an Ischemic Stroke
Consequences of Post Stroke Polysomnographic Abnormalities on Functionnal Recovery and Survival After an Ischemic Stroke
Ischemic stroke is a major public health issue, likely to cause functional disability. It is
 well known that sleep has an impact on brain plasticity, and after an ischemic stroke,
 studies have shown subjective sleep quality alterations and sleep architecture abnormalities.

 Furthermore, there is no clear guideline showing the usefulness of a systematic sleep
 investigation following an ischemic stroke.

 The aim of the study is to identify retrospectively correlation between polysomnographic
 abnormalities (sleep apnea, periodic limb movements, disturbed sleep architecture…) and
 functional recovery after an ischemic stroke. The study also assesses the impact of sleep
 abnormalities on survival, and the risk of new cardiovascular event.
This study is a retrospective observational study, from a cohort of patients who had a sleep
 recording (polysomnography or ventilatory polygraphy performed in Montpellier University
 Hospital) following an ischemic stroke.
Inclusion criteria:

 -  men and women, more than 18 years old

 -  medical history of ischemic stroke

 -  who had a sleep recording following the stroke

 Exclusion criteria:

 -  others types of strokes (bleeding, transient ischemic attack, cerebal veinous
 thrombosis)

 -  patients less than 18 years old
