2. The method of claim 1 further comprising administering a p450 3A4 promoter.
3. The method of claim 2 wherein the tyrosine hydroxylase inhibitor and the p450 3A4 promoter are administered simultaneously.
4. The method of claim 2 wherein the tyrosine hydroxylase inhibitor and the p450 3A4 promoter are administered orally, subcutaneously, intravenously, transdermally, vaginally, rectally or in any combination thereof.
5. The method of claim 4 wherein the transdermal administration is performed in combination with oleic acid, 1-methyl-2-pyrrolidone, or dodecylnonaoxyethylene glycol monoether.
6. The method of claim 2 wherein the tyrosine hydroxylase inhibitor and the p450 3A4 promoter are administered during a cycle consisting of five to seven days of administering the tyrosine hydroxylase inhibitor and the p450 3A4 promoter, and one to two days of not administering the tyrosine hydroxylase inhibitor and the p450 3A4 promoter.
7. The method of claim 6 that includes at least six of said cycles.
8. The method of claim 1 wherein the tyrosine hydroxylase inhibitor is α-methyl-L-tyrosine.
9. The method of claim 1 wherein the tyrosine hydroxylase inhibitor is α-methyl-D-tyrosine.
10. The method of claim 1 wherein the tyrosine hydroxylase inhibitor α-methyl-DL-tyrosine is in racemic form.
11. The method of claim 1 wherein 150-300 mg of the tyrosine hydroxylase inhibitor is administered daily.
12. The method of claim 11 wherein the tyrosine hydroxylase inhibitor is administered in three substantially equal doses.
13. The method of claim 2 wherein the p450 3A4 promoter is 5,5-diphenylhydantoin.
14. The method of claim 2 wherein the p450 3A4 promoter is valproic acid or carbamazepine.
15. The method of claim 1 wherein the subject is a mammal.
16. The method of claim 15 wherein the mammal is a human.
17. The method of claim 1 further comprising assessing progression of said autism in said subject.
18. The method of claim 2 further comprising assessing progression of said autism in said subject.
19. The method of claim 17 wherein said assessing step is performed after said administering step.
20. The method of claim 18 wherein said assessing step is performed after said administering step.
21. The method of claim 1 wherein the tyrosine hydroxylase inhibitor is administered orally, subcutaneously, intravenously, transdermally, vaginally, rectally or in any combination thereof.
22. The method of claim 21 wherein the transdermal administration is performed in combination with oleic acid, 1-methyl-2-pyrrolidone, dodecylnonaoxyethylene glycol monoether.
23. The method of claim 1 that reduces at least one of the following:
deficits in social-emotional reciprocity;
deficits in nonverbal communicative behaviors used for social interaction;
deficits in developing, maintaining, and understanding relationships stereotyped or repetitive motor movements, use of objects, or speech;
insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior;
highly restricted, fixated interests that are abnormal in intensity or focus; and
hyper- or hyporeactivity to sensory input or unusual interest in sensory aspects of the environment.
24. The method of claim 1 that reduces deficits in social-emotional reciprocity.
25. The method of claim 1 that reduces deficits in nonverbal communicative behaviors used for social interaction.
26. The method of claim 1 that reduces deficits in developing, maintaining, and understanding relationships stereotyped or repetitive motor movements, use of objects, or speech.
27. The method of claim 1 that reduces insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior.
28. The method of claim 1 that reduces highly restricted, fixated interests that are abnormal in intensity or focus.
