Dr. Campbell is a medical doctor with a postgraduate degree in neurology. She worked as a neurologist and a neurosurgeon for several years before starting a family. When her first-born son was diagnosed autistic at the age of three, she was surprised to realize that her own profession had no answers…
Back in 1984, when she graduated from medical school, autism was an exceptionally rare disorder, with a prevalence of about 1 in 10,000.
"By the time I graduated from medical school I had never seen an autistic individual," she says. "… To be honest, the first autistic child that I encountered was my own… Five years ago we were diagnosing one child in 150, which is almost a 40-fold increase in incidence. Now in Britain and some countries, we are diagnosing one child in 66."
The rates are similar in the United States, Australia, and New Zealand as well. She quickly delved into research, looking for an answer for her son, and ended up getting a second postgraduate degree in human nutrition. As a result of her work, her son fully recovered and is no longer autistic.
