What triggers narcolepsy?

Narcolepsy is often caused by a lack of the brain chemical hypocretin (also known as orexin), which regulates wakefulness. The lack of hypocretin is thought to be caused by the immune system mistakenly attacking the cells that produce it or the receptors that allow it to work.

Can an MRI detect narcolepsy?

Imaging studies such as MRI are useful for excluding rare causes of symptomatic narcolepsy. Structural abnormalities of the brain stem and diencephalon may present as idiopathic narcolepsy. In patients with secondary narcolepsy, MRI of the brain may show various abnormalities that correspond to the underlying cause.
