Brief Summary

Deficient sleep duration and sleep disturbances - such as insomnia, sleep disordered breathing (SDB) and restless legs syndrome (RLS)- are associated with hypertension and cardio-cerebrovascular morbidity and mortality. Several studies suggest that sleep disorders are frequent after stroke and detrimental for stroke outcome. However, more prospective studies in a large unselected sample of stroke survivors are needed to better investigate the short- and long-term consequences of sleep disturbances on mortality and occurrence of new cardio-cerebrovascular events. Also their pathophysiological mechanisms and their influence on stroke recovery should be better understood. Therefore, the aim of this study is to assess the impact of sleep deficiency and sleep fragmentation on the frequency of new cerebro- and cardiovascular events and death after stroke or transient ischemic attacks, and clinical outcome within one and two years after stroke. The working hypotheses are that stroke survivors with sleep deficiency and sleep fragmentation due to insomnia, sleep-disordered breathing or restless leg syndrome will present: (1) higher mortality from all causes and higher frequency of new cardio-/ cerebrovascular events; and (2) a less favorable clinical outcome. Outcomes will be compared between patients with and without sleep deficiency and fragmentation. Since current clinical practice in cerebrovascular patients does not sufficiently consider sleep disorders in patient's management, this study can help to bring attention to a still overlooked medical problem and change the current standard of management of stroke survivors.

Sampling MethodProbability Sample
Study Population

Patients suffering from ischemic stroke or transient ischemic attack (TIA) will be recruited at the Stroke Unit and the ward of the Department of Neurology, Inselspital Bern, and the Stroke Unit and ward of the Neurocenter of Southern Switzerland, Lugano, and followed-up for (at least) 2 (maximum 4) years. They will be evaluated for pre-existing and new-onset sleep disturbances that result in sleep deficiency (\< 6h sleep /night and/or post-stroke reduction of average sleep time/night ≥ 2h) or sleep fragmentation (insomnia, sleep-disordered breathing, restless legs syndrome).

You may qualify if:

  • Patients' informed consent as documented by signature.
  • Hospitalization either at the Stroke Unit and ward of the Department of Neurology, Inselspital Bern or at the Stroke Unit and ward of the Neurocenter of Southern Switzerland (Lugano)
  • Age: 18-85
  • Transient ischemic attack or ischemic stroke of any localization
  • Written informed consent

You may not qualify if:

  • Primary hemorrhagic stroke
  • Coma/Stupor
  • Clinical unstable or life threatening condition (severe heart failure, oxygen-dependent pulmonary disease or severe pulmonary complications, severe renal or liver insufficiency)
  • Pregnancy
  • Drug or alcohol abuse
  • Inability of the participant to give informed consent (e.g. patients under tutelage) or to follow the procedures of the study due to psychological or medical conditions
