Autoimmune Disorders
People with autoimmune disorders are especially at a higher risk of narcolepsy. This is because this disease affects your immune system and causes it to turn against the body. In other words, the immune system will attack your healthy tissue or cells, thus causing a loss of some brain cells which generate hypocretin. As a result, it leads to some common symptoms of narcolepsy. The condition would be worsened by a combination of environmental and genetic factors. [2]
