Use of lactulose in the treatment of autism
A treatment for autism in which an effective amount of lactulose is administered in order to bind excess ammonia in the gastrointestinal tract, the bloodstream, and the nervous system in order to prevent or reverse ammonia poisoning caused by the administration of certain antibiotics. Lactulose molecules in the colon are fermented by certain bacteria. The fermentation process lowers the colonic pH, and ammonia, in the form of ammonium ions, is used by the bacteria for amino acid and protein synthesis. This lowers the serum ammonia levels and reduces neurotoxicity.
1. A method for increasing a bacterial biomass in a colon of an individual diagnosed with an autistic disorder, comprising administering to the individual an effective amount of lactulose and an effective amount of mannitol, thereby increasing the bacterial biomass in the colon of the individual, wherein the method does not include administration of an antibiotic to the individual.
2. The method of claim 1 , wherein the effective amount of lactulose comprises about 0.4 g/kg lactulose per dose.
3. The method of claim 1 , wherein the effective amount of lactulose comprises about 0.3 g/kg lactulose per dose.
4. The method of claim 1 , wherein the effective amount of lactulose is administered to the individual approximately two to five times per day.
5. The method of claim 1 , wherein the effective amount of lactulose is administered to the individual in a form selected from the group consisting of a powder, a liquid solution, and a combination thereof.
6. The method of claim 1 , wherein the effective amount of lactulose includes an amount of lactulose sufficient to decrease ammonia levels in the blood of the individual.
7. The method of claim 1 , wherein the effective amount of lactulose includes an amount of lactulose sufficient to decrease ammonia levels in a gastrointestinal tract of the individual.
8. The method of claim 1 , wherein the effective amount of lactulose includes an amount of lactulose sufficient to decrease ammonia levels in a nervous system of the individual.
9. The method of claim 1 , wherein the effective amount of lactulose includes an amount of lactulose sufficient to reverse ammonia poisoning caused by the administration of antibiotics that leave a residue in a gastrointestinal tract of the individual.
10. The method of claim 1 , wherein the effective amount of lactulose is fermented by bacteria in a colonic tract of the individual.
11. The method of claim 10 , wherein fermentation lowers a colonic pH of the individual.
12. The method of claim 1 , wherein the effective amount of mannitol comprises about 0.1 g/kg mannitol per dose.
13. The method of claim 1 , wherein the bacterial biomass comprises lactobacilli and bifidobacteria.
