What
is Narcolepsy?
Narcolepsy is a neurological disorder,
which causes excessive sleepiness. This condition
usually develops in younger individuals, and is
lifelong. It is also associated with cataplexy (sudden
attacks of muscle weakness when the person has a
strong emotion), sleep paralysis, and hypnagognic
hallucinations (vivid dreams that occur as the person
falls asleep).
What are the signs and symptoms?
- Extreme sleepiness
- People with narcolepsy fall asleep unexpectedly
many times during the day. Not only can this
be embarrassing, but it can be very dangerous.
- Cataplexy (sudden attacks of muscle weakness
associated with strong emotions)
- Hallucinations just before falling asleep (usually
experienced as vivid dreams)
- Sleep paralysis (inability to move upon waking
up, lasting from a few seconds to a few minutes)
How is Narcolepsy diagnosed?
Following the initial evaluation by
the physician, a overnight sleep study is scheduled
along with a daytime sleep study called a Multiple
Sleep Latency Test (MSLT). The MSLT consists
of 4-5 naps each lasting approximately 20 minutes. This
is done to assess the degree of sleepiness and can
confirm the diagnosis of Narcolepsy.
What is the treatment?
Medications and good sleep hygiene
are the primary treatment modalities. Scheduling
20-30 minute naps at specific times throughout the
day can actually help reduce the uncontrollable
urge to sleep at undesirable times with less disruptions
to a persons daily schedule. |
