An adult client, diagnosed with narcolepsy, admits being embarrassed to receive this diagnosis and is adamant that no one find out about it. the nurse should respond to the client by explaining what aspect of the etiology?

The correct answer is "this is the result of neurological factors over which you have no direct control".
Narcolepsy is a neurological condition which blocks a person's ability to control its sleep-wake cycle. Common symptoms could be bad sleep quality, hallucinations while sleeping, sudden loss of muscle strength and excessive sense of sleepiness during the day. Being a neurological condition, patients have no control over their symptoms. The causes of the disorder are unknown, only a very small percentage of the cases (10%) is considered to be familial. Specific psychological conditions, such as trauma, are suggested to play a role. 

The answer is constant.
