Overview
Brief Summary
The purpose of this study is to look at the effect of using Mirtazapine to target a specific pathway in the body, that relies on a natural chemical the body produces called 'serotonin', in patients with spinal cord injury (SCI) and non-injured persons during sleep. During this part of the study participants will be asked to take Mirtazapine (15mg per day) and a placebo in a random fashion, each for a one week period (drug period) of time followed by one week without drugs (washout period). The drugs will not be taken all at the same time, but each will be taken separately for one weeks followed by a night study to look at the effect the Mirtazapine/placebo pill has on the way the body responds during sleep.
Detailed Description
Randomized placebo controlled cross-over study. Each subject will be studied on two separate occasions: (1) Mirtazapine vs. placebo for one week; the participants will be blinded to whether they are taking Mirtazapine or placebo. After the one week treatment a sleep study will be repeated. Mirtazapine will be given at 15 mg dose before bed-time. (2) Cross over medication for one week will be followed by a second sleep study.

Outcomes
Primary Outcomes
CO2 Reserve (Delta-PETCO2-AT)
Time Frame: One Week
Randomized placebo-controlled cross-over study. Each subject was studied on two separate occasions: (1) Mirtazapine vs. placebo for one week; After the one-week treatment a physiological sleep study was performed to determine the CO2 reserve (Delta-PETCO2-AT) and hypocapnic apneic threshold. (2) Cross over medication for one week was followed by a second physiological sleep study to determine the CO2 reserve (Delta-PETCO2-AT) and hypocapnic apneic threshold.
Secondary Outcomes
- AHI (Apnea/Hypopnea Index)(One Week)
