Method for preventing and/or treating chronic traumatic encephalopathy-I

1. A method of inhibiting tau hyperphosphorylation in a chronic traumatic encephalopathy (CTE) subject in need thereof, comprising:

selecting a subject diagnosed with CTE, and

administering to the subject a substance P receptor antagonist in an amount effective to inhibit tau hyperphosphorylation in the subject, wherein the substance P receptor antagonist is a NK1 receptor antagonist.

2. A method according to claim 1 , wherein the substance P receptor antagonist is administered to the subject at a dose of 0.25 mg/kg to 25 mg/kg.

3. A method according to claim 1 , wherein the NK1 receptor antagonist is one or more selected from the group consisting of Casopitant, CGP49823, CP-122,721, CP-96,345, CP-99,994, FK 888, GR 82334, GR 94800, GR203040, GR-205171, GSK1144814, GSK206136, GSK424887, GW679769, HSP-117, L 703,606, L 732,138, L 733,060, L 742,694, L668,169, LY 303241, LY 303870, LY 306740, Maropitant, MEN 11149, Orvepitant, PD 154075, R-544, RP-67580, RPR 100893, SCH619734, Spantide II, Spantide III, Spendide, SR140333, Vestipitant, WIN-41,708, WIN-62,577, and pharmaceutically acceptable salts thereof.

4. A method according to claim 1 , wherein the subject has suffered multiple concussive events.

5. A method of inhibiting tau hyperphosphorylation in a chronic traumatic encephalopathy (CTE) subject that has suffered multiple concussive events, comprising:

selecting a subject diagnosed with CTE and having suffered multiple concussive events, and

administering to the subject Casopitant at a dose of from 0.25 mg/kg to 25 mg/kg effective to inhibit tau hyperphosphorylation in the subject.
