GHB treatment has a high rate of success in reducing cataplexy, sleep attacks, sleep paralysis, and hypnagogic hallucinations
Other types of medications help control cataplexy, sleep paralysis and hypnagogic hallucinations
, but for various reasons are not widely used.
The patient reported here initially presented with hypnagogic hallucination
but no dreams.
Narcolepsy is accompanied by the proliferation of histamine neurons, which can cause classic symptoms of narcolepsy, such as cataplexy and hypnagogic hallucinations
For example, REM sleep suppression may help with cataplexy and the hypnagogic hallucinations
Barnhill's patient swayed the author though the patient already has a psychotic illness (as well as many other possible contributors such as drug use), but even in sleep disorders hypnopompic or hypnagogic hallucinations
are neither exclusive to narcolepsy, nor particularly pathognomonic.
About 30%-60% of narcoleptic patients have sleep paralysis, a similar proportion have hypnagogic hallucinations
, which occur at sleep onset.
Symptoms of narcolepsy include excessive daytime sleepiness (even dropping off to sleep at any time, whether it be watching TV or driving a car), cataplexy (brief episodes of muscle weakness brought on by strong emotion), sleep paralysis (inability to move occurring at the moment of failing asleep), and hypnagogic hallucinations
(dreamlike images that occur at sleep onset).
Narcolepsy is a complex, lifelong neurological disease characterized by fragmented nighttime sleep, excessive daytime somnolence (EDS), cataplexy, sleep paralysis, and hypnagogic hallucinations
22) Complex visual hallucinations in epilepsy are similar to hypnagogic hallucinations
but are rare.
Classic narcolepsy patients display the clinical 'tetrad'--cataplexy, hypnagogic hallucinations
, daytime sleep attacks and sleep paralysis.
