Question:

Does anyone have information on what exactly is an alpha intrusion. It was discovered in my initial sleep study.

When the brain is awake, it has lots of alpha waves.  During deep sleep the brainwave patterns should switch mostly to delta waves (slow waves).  But sometimes, the alpha wave patterns tend to intrude.  This often results in an arousal (movement from deep sleep to lighter sleep).  If this occurs frequently, it results in minimal (or no) deep sleep, with resulting sleep deprivation. What causes this not understood.  However, it does seem to be a common problem amoung folks that have Fibromyalgia.  Having alpha wave intrusion does not mean you have fibro.  But having fibro seems to indicate alpha wave intrusion might be present. Some medications help restore a natural sleep pattern to sleep.  Trazodone (in subclinical dosages – not high enough to act as an antidepressant) seems to be one that helps. Regards, =jbf= John B.

IMHO periodic breathing will also cause alpha intrusions John John B.
