Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is looking at problems people sometimes have taking in information from their senses. Specifically, we are comparing the way in which people diagnosed with schizophrenia process sound information, compared with people who have never been diagnosed with a psychiatric disorder. When people hear a loud sound they sometimes feel startled, and when they feel startled they usually blink their eyes. However, if they hear a softer sound shortly before the loud one they may not blink their eyes - in other words, the eye-blink response is smaller. When this happens it's called prepulse inhibition of startle. In this study, we want to measure the startle response and prepulse inhibition of startle in individuals diagnosed with schizophrenia versus individuals not diagnosed with schizophrenia. We also want to find out whether people show the same amount of prepulse inhibition of startle as other members of their family.
