Post Traumatic Stress Disorder (PTSD), Sleep Disordered Breathing And Genetics: Effects On Cognition
Trial ID: NCT01120847
The current research program aims to study how sleep disordered breathing, age and genetics affect memory in older adult veterans with Posttraumatic Stress Disorder (PTSD). The study will help researchers and clinicians better understand the relationship among PTSD, sleep disordered breathing, genetics and memory function.

2. PTSD subjects will be positive for lifetime PTSD, related to any past lifetime
traumatic experience and have a diagnosis of current, chronic PTSD by the Clinician
Administered PTSD Scale (CAPS) criteria with current CAPS score > 40
3. Capable of giving informed consent for the study
4. Sufficient visual and auditory acuity for cognitive testing
1. Current or lifetime history of any psychiatric disorder with psychotic features
2. Current or lifetime bipolar disorder or delusional disorder

9. History of seizure disorder.
1. Acute illness or unstable chronic illness (e.g., history of severe liver disease

Clinical or laboratory evidence of active hepatic disease will be recorded.
2. History of neurologic (e.g., multiple sclerosis, seizure disorder, stroke, history of
transient ischemic attacks) or systemic illness affecting central nervous system (CNS)
function (e.g. liver failure, kidney failure, congestive heart failure, systemic
3. Unstable or severe cardiovascular disease
4. Unstable gastrointestinal disorder
5. Uncontrolled hypertension
6. Head injury within one year
7. Loss of consciousness >24 hrs
8. Use of systemic steroid medication (with the exception of Estrogen replacement therapy
which is permissible)
9. Illiterate or unable to read or write English or are judged by the investigator to be
unable or unlikely to follow the study protocol
10. Toxicology evidence of illicit substance use.
