Sleep problems can cause Stroke

Posted Jul 01 2008 12:00am

Obstructive Sleep Apnoea (OSA) and Stroke

OSA and Heart

The repeated pauses in breathing deny oxygen supply to the brain. The increase in the carbon dioxide level activates the sympathetic nervous system. This in turn causes spikes in the blood pressure and increases the blood pressure and the heart rate. A systemic cardiac resistance develops when there is a change in the volume of blood pumped into the heart.

People suffering from undiagnosed OSA have an increasing mortality rate. A lot many people are treated for cardiovascular diseases. But many OSA patients go untreated mainly because they or their partners do not recognize the symptoms.

The symptoms of Obstructive Sleep Apnea are as follows :

  • Load and heavy snoring
  • Apnea or pauses in breathing during sleep.
  • Sleepiness and headache in the morning
  • Memory loss
  • Inability to concentrate
  • Weight gain
  • Lethargy
  • High Blood Pressure
