What is the significance of alpha intrusion in sleep study?

Postby Arizona » Sun Dec 09, 2012 11:15 pm

My titration sleep study showed an EEG abnormality of alpha intrusion; is this significant?

Our bodies do most of their healing, restorative work during sleep, such as producing growth hormones and antibodies. Alpha waves can interfere with the delta waves in nonREM sleep, PERHAPS reducing this restorative stuff to happen.

Alpha waves are usually present during relaxed wakefulness. The exact science of what is going on when alpha waves are present in nonREM sleep is still unclear. There is more alpha wave intrusion with people with any type of chronic pain and depression than there are in the general population, but the correlation is unknown. It is not considered to be causal, but may be a symptom of the other conditions.

Alpha waves indicate a level of awareness while sleeping -asleep but not asleep, aware but not awake. I wonder if they've ever done studies of mothers of young babies, who are attuned to listening for the babies while they are asleep?
It is an indicator of nonrestorative sleep, or insufficient quality of sleep.

Thank you for your answers. I have had chronic pain since 1989, and intractable pain since 2009. Outside of continuing to find ways to address the pain from its sources, can cpap therapy assist in offering correction of the intrusions?

The answer to your question is: maybe. If you are having respiratory arousals, that bring you to that half awake/half asleep state, then you may have less alpha wave intrusion. If you are having arousals due to insufficient pain relief, then maybe not. But if you have sleep apnea, you need the cpap anyway!
