Pertussis vaccine immunizations each year in the United States), and the risk of death from the disease was high (pertussis killed thousands of Americans each year before the vaccine was introduced). No studies showed a causal connection, and later studies showed no connection of any type between the DPT vaccine and permanent brain injury. The alleged vaccine-induced brain damage proved to be an unrelated condition, infantile epilepsy. In 1990, the "Journal of the American Medical Association" called the connection a "myth" and "nonsense". However, negative publicity and fear-mongering caused the immunization rate to fall in several countries, including the UK, Sweden, and
Alexander disease the ability to talk. It also causes an overload of long-chain fatty acids in the brain, which destroy the myelin sheath. The cause of Alexander disease is a mutation in the gene encoding GFAP. A CT scan shows: Detecting the signs of Alexander disease is possible with magnetic resonance imaging (MRI), which looks for specific changes in the brain that may be tell-tale signs for the disease. It is even possible to detect adult-onset Alexander disease with MRI. Alexander disease may also be revealed by genetic testing for its known cause. A rough diagnosis may also be made through revealing
