Feasibility and ML Training Investigation of the Senseye DT for Diagnosis of Adults with PTSD

Prior treatment

• Active suicidal and/or homicidal intent which may put the participant and/or others at risk per the investigator's clinical judgement, or has suicidal ideation with intent to act within 6 months prior to the start of the screening phase as determined by a C-SSRS score \> 3, or history of suicidal behavior within the past year prior to the start of the screening phase.
• Current reported usage (within 2 weeks of Initial Study Visit and/or planned ongoing usage during the study) of psychotropic and/or non-psychotropic drugs/medication which may affect use of the Senseye DT (complete list in full protocol).
• Current reported usage (within 2 weeks of Initial Study Visit and/or planned ongoing usage during the study) of vagal nerve stimulation, deep brain stimulation, transcranial magnetic stimulation, or electroconvulsive therapy.

Other illness

• Current diagnosis of epilepsy and/or other current seizure disorders.
• A history of or positive at screening for bipolar I or II, mania, or one or more schizophrenia-spectrum or other psychotic disorders, including schizophrenia, schizoaffective disorder, delusional disorder, and psychosis.

• Current eye disorders which prevent the patient from using the Senseye DT (complete list in full protocol).
• Any condition which precludes the ability for subjects to safely and accurately complete clinical assessments, questionnaires, or to follow instructions necessary to administer the Senseye DT (e.g., significant developmental disabilities, language disorders, cognitive deficiencies, or other neurodevelopmental disorders).
• Lifetime history of any of the following: surgical procedures involving the brain or meninges, encephalitis, meningitis, degenerative central nervous system (CNS) disorder (e.g., Alzheimer's Disease, Parkinson's Disease), epilepsy, mental retardation, or any other disease/procedure/accident/intervention that, according to the clinician, is deemed associated with significant injury to, or malfunction of, the CNS.
