We try not using medications initially, and we use something called behavioral therapy for insomnia. This changes behaviors people do in bed, none of the tossing and turning.

If you're going somewhere East from here, generally what you want to do is you want to try to have your bed time earlier and earlier so what we'll do is I'll have someone adjust for a week or two by going to be 15 minutes earlier and getting up 15 minutes earlier every night. So that can be a really simple thing.

So someone who is a child usually goes to bed about 8:00 or 9:00 at night, but then when they have a circadian rhythm shift, it shifts later. And this is natural. And they start to go to bed at 11:00, 12:00, 1:00 and they want to sleep later. So we see this a lot in teens.

So, sleep deprivation, and sometimes an insomnia, which is a little bit of a different form, but just getting a lack of sleep, can lead to a number of different decrements.

The other option we have are medication treatments. So you'll have the treatments such as Ambien, Lunesta, Sonata, and we'll also have Rozerem and for some patients we use Benzodiazopine/Clonazepam. Things like that to help with anxiety.

Now circadian rhythms become very interesting and problematic for patients because when you become a teenager, your rhythms actually tend to naturally shift.

So when it comes to circadian rhythms, it's a clock that's basically programmed in our body. So if you think back to times when people lived on farms and we didn't have electricity.
