The researchers identified the cause as a single mutation, or change, in the structure of a gene known as PRRT2. Genetic testing showed the mutation affected 19 of the 23 families.
University of South Australia’s Susan Heron said babies with the disorder often suffer seizures from the age of six months. The children outgrow the seizures after a year or two, but can develop a movement disorder.
The World Health Organization estimates that 50 million people around the world have epilepsy. Nearly 90 percent of cases are in developing countries. The WHO says many people in these areas suffer from epilepsy because of local conditions. In developing countries, people have a greater chance of experiencing a medical condition or disease that can lead to permanent brain damage.
The WHO says misunderstandings about epilepsy have resulted in laws against people with the disorder. For years, it was not illegal for American businesses to discriminate against individuals who suffered seizures. Now, a law called the Americans with Disabilities Act of 1990 protects the civil rights of people with disabilities in the United States.
The World Health Organization says many people with epilepsy receive no treatment. However, many treatments are available.
Generally, medicine is the first treatment of choice for epilepsy. The Epilepsy Foundation of America says different kinds of medicines can stop or control different kinds of seizures. There are now more than 20 kinds of drugs on the market. These drugs work best only after they reach what experts call a desired level in the body. It might take months to identify the right drug to control the disorder because each one may cause problems. These include weight gain or loss, eye or stomach problems, sleepiness and loss of balance. Some people may suffer depression, or have problems thinking or talking after taking some drugs.
