What this trial measures

• Heart Rateup to 2 years

  Evaluating the heart rate of the subject every hour during all the test procedures

• Pulse Rateup to 2 years

  Evaluating the pulse rate of the subject every hour during all the test procedures

• Stanford Sleepiness Scaleup to 2 years

  The subject will rate how sleepy they are feeling at baseline and every hour during the test using an (8) point scale (i.e. 1= feeling active, vital alert, or wide awake; 2= functioning at high levels, but not fully alert; 3= awake, but relaxed, responsive but not fully alert; 4= somewhat foggy, let down; 5= foggy, losing interest in remaining awake, slowed down; 6= sleepy, woozy, fighting sleep, prefer to lay down; 7= no longer fighting sleep, sleep onset soon, having dream-like thoughts; 8= asleep

• Epworth Sleepiness Scaleup to 2 years

  The subject will rate their pre-test sleepiness only once during the test using a (4) point scale (0= no chance of dosing, 1= slight chance of dosing, 2= moderate chance of dozing and 3= high chance of dozing

• Fatigue Severity Scaleup to 2 years

  The subject will rate their pre-test fatigue only once during the test by rating 10 questions using a slide scale between 1 and 7. A rating of 1 means the subject strongly disagrees with the statement. A rating of 7 means the subject strongly agrees with the statement.

• Chalder Fatigue Scaleup to 2 years

  Subjects will rate their fatigue every hour and at baseline by answering 11 questions and rating their fatigue using a 4 point scale (i.e. less than usual, no more than usual, more than usual and much more than usual)

• Psychomotor physical computerized testup to 2 years

  The participants uses a computerized test to test their reflexes every hour and at baseline during the trial period. Every time a red dot appears in the middle of the screen the participant must touch the computer screen as fast as they can. This test was measured in how fast they responded (ms) and by how many attempts to touch the screen were recorded in 2 minutes

• Hand Fatigue Scaleup to 2 years

  A hand grip measuring device will be used to test for fatigue. A small hand held device will measure the participants hand grip strength every hour during the test and at baseline.

• Electroencephalogramup to 2 years

  Electroencephalogram will be taken at baseline and after subjects have taken the anti-psychotic medication. There will be no placebo taken for this test.
