    • Ben Harder published a story on the affects and one possible cure for narcolepsy. Although this was not an experiment per say but it was research in the form of a survey and observation from other doctors. In one case of narcolepsy, a young boy stopped having narcoleptic attacks for a period of time after injected with large intravenous dose of molecules called immune globulin's. His attacks returned and he had to have continuous injections. Later, scientists discovered an inhibitory medication called orexin; a pill that could be taken to prevent attacks. Scientists still know little about the disease and have concluded through patients that it is caused by something in the patients surrounds.


  • A study carried out on dogs showing that there is an uncommon deformity in dogs' brain that blocks a response to orexinand it manufactures a "dog" form of narcolepsy. Researchers found that people with narcolepsy are missing orexin, also referred to as orexin deficiency in narcolepsy. They started to replace the drug in dogs to confirm whether people dealing with narcolepsy could use the same method. Researchers compared this experiment to giving insulin to people with diabetes. They state that the replacement drug is very helpful although, it is not long term; meaning, patients receiving the replacement drug would need frequent doses.

  • Narcolepsy is a complex disorder that deals with sleep-related brain activities that, at night, occur at random times throughout the day. A studied was tested on an 8 year old boy who was a very healthy and outgoing child, who one day, just found it extremely hard to stay awake as well as having hallucinations. The poor boy was withdrawn from school as well as not participating in anymore extracurricular activities which included his favorite, tae kwon do. Diagnosis for the doctors at Glaslow's Royal Hospital for Sick Children was easy, severe narcolepsy. Unfortunately, the medications for regular narcolepsy did not treat this boys condition. They put the boy on 'immune globulins', a very strong drug. Dr. Zuberi was predicting that the narcolepsy was caused form an immune attack which controls the brains wakefulness and sleep system. Those immune globulins lasted for about three months in the boys body before he felt the symptoms of the narcolepsy return. He has already been back to the hospital for his third round of treatment.
