Compositions containing PUFA and methods of use thereof
This invention provides methods of increasing or enhancing the synthesis and levels of phospholipids, synapses, synaptic proteins, and synaptic membranes by a neural cell or brain cell; methods of treating a subject with a memory disorder, memory impairment, neurological disorder, or brain disease or disorder, comprising administering to the subject a composition comprising an omega-3 fatty acid, an omega-6 fatty acid, uridine, a metabolic precursor thereof, or a combination thereof.
1. A method of increasing an amount of a synaptic membrane of a neural cell or brain cell of a subject comprising
administering to said subject in need of such treatment a therapeutically effective amount of a composition having:
(a) an omega-3 fatty acid, an omega-6 fatty acid, or a combination thereof;
(b) uridine, an acyl derivative thereof, a uridine phosphate or a CDP-choline; and
(c) a choline salt,
wherein uridine, an acyl derivative thereof, a uridine phosphate or CDP-choline is dosed to provide a range of 10 to 500 mg of uridine per day and choline is dosed in a range of 100 mg to 10 g per day.
2. The method of claim 1 , wherein said subject has a memory disorder selected from the group consisting of Alzheimer's disease, Pick's disease, Lewy Body disease, Huntington's disease and mild cognitive impairment.
3. The method of claim 1 , whereby the composition increases a synthesis of a phospholipid in a neural cell or brain cell of said subject.
4. The method of claim 3 , wherein said phospholipid is a phosphatidylcholine, a phosphatidylethanolamine, a phosphatidylinositol, a phosphatidylserine, or a sphingomyelin.
5. The method of claim 1 , wherein said omega-3 fatty acid is docosahexaenoic acid, eicosapentaenoic acid, alpha-linolenic acid, or a combination thereof.
6. The method of claim 1 , wherein said omega-6 fatty acid is arachidonic acid, linoleic acid, or a combination thereof.
7. The method of claim 1 , wherein said uridine phosphate is a uridine-5′-monophosphate (UMP), uridine-5′-diphosphate (UDP), uridine-5′-triphosphate (UTP), or is a salt of said UMP, UDP or UTP.
8. The method of claim 7 , wherein said uridine phosphate is a uridine-5′-monophosphate (UMP).
9. The method of claim 1 , wherein the choline salt is choline chloride, choline bitartrate or choline stearate.
10. The method of claim 1 , wherein the composition is a medicament or nutritional supplement.
11. The method of claim 1 , wherein the composition comprises between about 200 mg and about 800 mg of a choline salt.
12. The method of claim 1 , wherein the composition comprises uridine-5′-monophosphate (UMP), a choline salt and docosahexaenoic acid.
13. A method of increasing a size or number of synapses in a brain of a subject, comprising
administering to said subject in need of such treatment a therapeutically effective amount of a composition comprising
(a) an omega-3 fatty acid, an omega-6 fatty acid, or a combination thereof;
(b) uridine, an acyl derivative thereof, a uridine phosphate or a CDP-choline, and
(c) a choline salt,
wherein uridine, an acyl derivative thereof, a uridine phosphate or CDP-choline is dosed to provide a range of 10 to 500 mg of uridine per day and choline is dosed in a range of 100 mg to 10 g per day.
14. The method of claim 13 , wherein said subject has a memory disorder selected from the group consisting of Alzheimer's disease, Pick's disease, Lewy Body disease, Huntington's disease and mild cognitive impairment.
15. The method of claim 13 , whereby the composition increases a synthesis of a phospholipid in a neural cell or brain cell of said subject.
16. The method of claim 15 , wherein said phospholipid is a phosphatidylcholine, a phosphatidylethanolamine, a phosphatidylinositol, a phosphatidylserine, or a sphingomyelin.
17. The method of claim 13 , wherein said omega-3 fatty acid is docosahexaenoic acid, eicosapentaenoic acid, alpha-linolenic acid, or a combination thereof.
18. The method of claim 13 , wherein said omega-6 fatty acid is arachidonic acid, linoleic acid, or a combination thereof.
19. The method of claim 13 , wherein said uridine phosphate is a uridine-5′-monophosphate (UMP), uridine-5′-diphosphate (UDP), uridine-5′-triphosphate (UTP), or is a salt of said UMP, UDP or UTP.
20. The method of claim 19 , wherein said uridine phosphate is a uridine-5′-monophosphate (UMP).
21. The method of claim 13 , wherein the choline salt is choline chloride, choline bitartrate or choline stearate.
22. The method of claim 13 , wherein the composition is a medicament or nutritional supplement.
23. The method of claim 13 , wherein the composition comprises between about 200 mg and about 800 mg of a choline salt.
24. The method of claim 13 , wherein the composition comprises uridine-5′-monophosphate (UMP), a choline salt and docosahexaenoic acid.
