Neurological System

A nerve impulse is an electric signal which travels through an axon. When it reaches the end of the axon, neurotransmitters are released by the axon. It is through these neurotransmitters which travel from one axon and dendrite of the next neuron (McCance & Huether, 2014).

The Central Nervous System (CNS) functions by coordinating everything taking place throughout the body. It is subdivided into the brain and the spinal cord. The Peripheral Nervous System (PNS) is an extension of the CNS. The primary function of the PNS is to connect the CNS to the other organs of the body such as the limbs.

The diagnosis of the 35-year-old man is to undergo the recommended test. Sleep studies are one of them so that more of the condition is studied. The other test is the polysomnogram (PSG) which assists in finding out if one sleeps quickly, go into REM quickly or wake up during the night. The other test is a multiple sleep latency test, performed during the day where the person is supposed to sleep for about 20 minutes every two hours (Turner, Cikurel & Bahra, 2006).

Narcolepsy, the condition the man is suffering from, is caused by the lack of hypocretins. These are chemicals which make one alert and help in the prevention of REM state. Since they are produced in the hypothalamus, the condition affects that part of the brain. 

The sleep state which the symptoms resemble is the REM (Rapid Eye Movement) state. This is the state where there is the most active dreaming (Montagna & Chokroverty, 2011).

The Electroencephalogram (EEG) measuring the condition will show lateral rectus spikes when the patient is in the REM. 

Narcolepsy still has no cure, but there is a combination of treatments which can be used to control the narcoleptic symptoms. One of them is to have to counsel and supporting groups since depression contributes to the symptoms. Secondly, the patient can change their lifestyle so that they can ease the symptoms. Exercising and a proper diet can contribute to controlled and managed conditions (Montagna & Chokroverty, 2011).
