12The episodes of sudden muscle tone loss that is associated with 70% of narcolepsy patients is known as [blank_start]cataplexy[blank_end]
- Acataplexy
13Cataplexy is a sudden loss of muscle tone in response to ...
- AAn emotion such as fear, surprise or joy
- BA transient drop in blood pressure caused by activities such as standing up too quickly
- CHallucinations that tend to occur spontaneously throughout the day
- DA sudden temperature drop
14Narcolepsy with cataplexy has a known cause: a loss of cells in the brain that secrete a hormone responsible for wakefulness called ...
- AHypocretin
- BHippocretin
- CMelatonin
- DHypotonin
15Investigations for Narcolepsy:
[blank_start]Overnight Polysomnography[blank_end]: A comprehensive recording of the biophysiological changes that occur during a normal sleep duration
[blank_start]Multiple Sleep Latency Test[blank_end]: Four 25 minute naps around 2 hours apart in order to test brain activity and eye movement
[blank_start]Lumbar puncture[blank_end]: Measures the levels of Hypocretin being produced by the brain- AOvernight Polysomnography
- BMultiple Sleep Latency Test
- CLumbar puncture
16What is REM Behaviour Disorder (RBD)?
- AA disorder whereby people act out their dreams. The normal atonic nature of muscles during REM sleep is not present.
- BA disorder whereby people actively dream during the day. Like narcolepsy, this condition is also related to hypocretin levels in the brain.
- CA condition whereby an individual wakes up upon initiation of REM sleep, meaning they must sleep in smaller sections and can never get a full night's sleep.
17Which hormone supplement can be given to REM Behaviour Disorder patients in attempt to improve their sleep?
