3. The method of claim 1 , wherein the patient is administered a composition comprising about 1 mg to about 15 mg gaboxadol or a pharmaceutically acceptable salt thereof.
4. The method of claim 1 , wherein the in vivo plasma profile of the patient 6 hours after administration of the gaboxadol or pharmaceutically acceptable salt thereof is reduced by more than 50%.
5. The method of claim 1 , wherein the AUC 6-12 of the patient 6 hours after administration of the gaboxadol or pharmaceutically acceptable salt thereof is less than 75% of the administered dose.
6. The method of claim 1 , wherein the method provides improvement in at least one symptom selected from the group consisting of repetition of sounds, repetition of syllables, repetition of words, prolongation of sounds, blocks and struggle behaviors.
