Central Nervous System vs Peripheral Nervous System: The central nervous system (CNS) consists of the brain and spinal cord and is responsible for coordinating voluntary movements and controlling information processing within the body. The peripheral nervous system (PNS) consists of all nerves outside of the CNS which collect sensory information from our environment, regulate involuntary bodily functions such as breathing or digestion, and relay motor commands from our brains back out into our muscles.
Probable Diagnosis Narcolepsy: Narcolepsy is caused by dysfunction of various regions in both sides of the brain including the hypothalamus, amygdala & locus coeruleus which are involved in regulating circadian rhythm & sleep/wake cycles . Other areas affected include thalamus & prefrontal cortex which play key roles in controlling arousal states & REM sleep respectively .
Sleep State Resembled : Symptoms exhibited by this patient closely resemble those experienced during REM sleep , where individuals experience vivid dreams , paralysis-like sensations while sleeping etc . Additionally narcolepsy has been associated with significant increases in REM latency , meaning patients enter this state sooner than normal causing them to fall asleep relatively quickly during daytime hours even when feeling aroused/energized .
