Recovering and Regaining Independence

Each patient’s recovery and rehabilitation is important to us. Before being discharged, our stroke care coordinator will meet with each patient and caregiver to discuss topics associated in the recovery process. Some of these topics include care at home following a stroke and reducing risk of another stroke. After discharge from the Oklahoma Stroke & Neurological Institute, the Kaiser Rehabilitation Center at Hillcrest Medical Center offers inpatient and outpatient rehabilitation services on the Hillcrest campus.

Two million brain cells die every minute the brain goes without oxygen.

Stroke or “Brain Attack” occurs when a blood clot blocks an artery or a blood vessel breaks, causing a disruption of blood flow to the brain. The quality of medical care you receive in the first minutes and hours after a stroke can save your life and determine how well you will recover.
