Peripheral Nervous System and Central Nervous System. The central nervous (CNS), which is made up of the spinal cord, brain, and other nerves in the spine, controls information processing and coordinates voluntary movement. The peripheral nervous (PNS), which is all the nerves that are outside of our CNS, collects sensory information about our surroundings, controls involuntary functions like breathing and digestion, as well relays motor commands back from our brains to 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 .
This patient’s symptoms closely resembles those of REM sleep, when individuals have vivid dreams and paralysis-like feelings while asleep. narcolepsy also has an increased REM-latency. This means patients are able to enter REM earlier than usual, causing them fall asleep quickly in the daytime even if they feel energized.
