The methods can include administering the subject an effective amount of 4,5,6,7-tetrahydroisoxazolo (5,4-c)pyridin-3-ol (THIP) or a derivative thereof, or a pharmaceutically acceptable salt thereof, increase tonic inhibition in neurons of the subject; to increase slow wave sleep (SWS) and/or slow wave activity (SWA), normalize sleep architecture, reduce secondary insomnia, increase non-rapid eye movement (NREM) sleep, increase sleep continuity, enhance delta activity within NREM, increase or improve total sleep time (TST), increase or improve sleep efficiency, reduce total time awake (TAA), reduce number of awakenings (NWA), reduce latency to persistent sleep (LPS), or to reduce wake after sleep onset (WASO), in the subject, or any combination thereof.

2. The method of claim 1 , wherein the patient is administered 10 mg to 30 mg of THIP or a pharmaceutically acceptable salt thereof.
3. The method of claim 1 , wherein the patient is administered 10 mg to 20 mg of THIP or a pharmaceutically acceptable salt thereof.
4. The method of claim 1 , wherein the total amount of THIP or a pharmaceutically acceptable salt thereof administered to the patient in a 24-hour period is between 10 mg and 50 mg.
5. The method of claim 1 , wherein the daily dosage of the THIP or a pharmaceutically acceptable salt thereof is between 10 mg and 20 mg.
