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.

Disclosed is a method and apparatus for estimating the amount of ammonia output from a Selective Catalytic Reduction (SCR) device 20 located in the exhaust system of a vehicle powered by an internal combustion engine. A NOx sensor 44 is located downstream of the SCR to monitor the output of the SCR device and provide data for controlling the dosage of a reductant supplied to the SCR. The NOx sensor is sensitive to NOx which may be output from the SCR when it is under-dosed but is also sensitive to ammonia which may be present when the SCR is over-dosed. Consequently the signal from the NOx sensor is a combination of the NOx and / or ammonia levels in the exhaust. The method and apparatus for estimating the amount of ammonia output from the SCR determine a NOx conversion efficiency of the SCR using a variance of a NOx input measurement from a NOx sensor 42 located upstream of the SCR and a variance of a NOx output measurement from the NOx sensor 44 located downstream of the SCR. An estimate of the actual NOx output from the SCR is then determined using the measured NOx input value and the NOx conversion efficiency of the SCR. The resulting estimate of NOx output is used in conjunction with the measured NOx output to determine the ammonia output by subtracting the estimated NOx output from the measured NOx output to provide an estimate of the ammonia output.
