Rosemary Waring

From Wikipedia, the free encyclopedia

Rosemary Waring, a reader in human toxicology at the School of Biosciences, University of Birmingham, was the first researcher to produce scientific evidence suggestive of abnormal sulphur metabolism affecting people with autistic spectrum disorders. Her findings suggest that people with autism present with consistently lower levels of circulating plasma sulphate and higher than normal levels of urinary sulphate than non-symptomatic controls (reflective of excessive 'dumping' of sulphate into the urine). Follow-up work has suggested that people with autism also present with higher than normal levels of other sulphur-related compounds, including sulphite.

Dr. Waring found that most people with autism conditions have a deficiency in a key detoxification pathway involved with sulfation. The enzyme involved is phenol sulfur-transferase (PST), which is essential to the process of breaking down and removing certain toxins from the body. Waring postulates that symptoms arise from an inadequate supply of usable sulfate ions, rather than from a deficiency of the metabolic enzyme itself. Her findings have been very influential in the field of biomedical interventions in autism.(see: autism therapies).
