Cataplexy
Cataplexy is a sudden lack of muscle tone or muscle weakness, sometimes resulting in the complete paralysis of voluntary muscles. This condition is a common symptom of narcolepsy, analogous to the muscle atonia experienced during REM sleep. However, the presentation of cataplexy can vary among individuals; for instance, in some unusual cases, the weakness may be confined to only one side of the body.

Case Study of Narcolepsy: Symptom Variability and Combination Therapy
A patient reports experiencing overwhelming daytime sleepiness, causing them to fall asleep unexpectedly during meetings. They also describe episodes where strong emotions, like laughter, trigger a sudden, temporary loss of muscle control, causing them to slump over. Additionally, they mention having vivid, dream-like visions just as they are falling asleep. Based on this specific combination of symptoms, which of the following is the most likely condition?
