Context: NIMHANS sleep disorders database
NIMHANS and IIIT Hyderabad have launched iSLEEPS, Asia’s first open-access sleep database for ischemic stroke patients.
The aim is to strengthen research and improve post-stroke care.
Institutions Involved
NIMHANS
IIIT Hyderabad
- International Institute of Information Technology, Hyderabad
iSLEEPS Database
Full Form
- Polysomnography Dataset for Sleep Analysis in Ischemic Stroke Patients
Key Features
- Asia’s first open-access sleep database for ischemic stroke patients.
- Contains 100 overnight polysomnography recordings.
- Data collected between 2018 and 2021.
- Published in Scientific Data, Nature Portfolio.
What Does It Record?
The database records:
- Sleep stages
- Breathing disorders
- Oxygen desaturation
- Limb movements
- Clinical data
Why Is It Important?
- Addresses lack of high-quality sleep datasets in Asia.
- Supports AI-based diagnosis.
- Helps global sleep and stroke research.
- Improves post-stroke rehabilitation.
- Helps detect sleep-disordered breathing early.
- May reduce risk of recurrent stroke.
Polysomnography
Polysomnography is the gold-standard overnight sleep test used to diagnose sleep disorders.
It records parameters such as:
- Brain activity
- Breathing
- Oxygen levels
- Heart rate
- Limb movement
- Sleep stages
Ischemic Stroke
Ischemic stroke occurs due to blockage of blood supply to the brain.
It accounts for around 85% of all strokes.
