Treatment of EDS

The first step is to perform the Multiple Sleep Latency Test (MSLT) to assess the overall sleepiness and diagnosing the abnormalities in the sleep for any obvious causes of sleep disruption in the night that could affect the daytime symptoms. Post this test, the pharmacotherapy is achieved with the use of stimulants like amphetamine sulfate and methylphenidate and any alerting agents like modafinil.
