简要总结
The primary objective of this study is to evaluate the effects of plasticity-based, adaptive cognitive remediation on the cognitive abilities, functional status and quality of life of soldiers and veterans diagnosed with persistent post-concussive symptoms (PPCS) following a mild traumatic brain injury (mTBI, also referred to as a concussion, or blast exposure), as compared to a computer-based control.
详细描述
This study is a multi-site, prospective, parallel arm, double-blind, randomized, controlled clinical trial to assess the safety and efficacy of plasticity-based, adaptive, computerized cognitive remediation treatment versus a computer-based control. Both the study and the cognitive remediation treatments meet the criteria of Non-Significant Risk.

入选标准
- •Subjects must be 18 - 50 years of age at the time of consent
- •Subjects must have a diagnosis of mTBI
- •Subjects must have persistent cognitive dysfunction confirmed by an objective measure (as recommended by the ICD-10 definition for post-concussion syndrome) or a subjective measure (as recommended by the DSV-IV definition of post-concussional disorder).
- •Subjects must be at least three months out from their most recent TBI, concussion, and/or blast exposure to minimize the effects of spontaneous recovery, as verified through participant interview.
- •Subjects must be fluent English speakers.
- •Subjects must have adequate sensorimotor capacity to perform the program in the judgment of the consenting clinician.
排除标准
- •Subjects must not have a history of penetrating head wounds or a diagnosis of moderate or severe TBI.
- •Subjects must not be in-patients.
- •Subjects must not have a diagnosis of an illness or condition with known cognitive consequences (e.g., schizophrenia, bipolar disorder, cancer, multiple sclerosis).
- •Subjects must not show suicidal ideation as measured by the Columbia-Suicide Severity Rating Scale (C-SSRS).
- •Subjects must now show signs of intoxication due to current substance abuse (including alcohol and/or illegal drugs) during any in person visit.
- •Subjects must not have clinically significant visual field deficits noted by the consenting staff member by direct observation or by medical history.
- •Subjects must not be judged to be lacking effort.
- •Subjects must not have problems performing assessments or comprehending or following spoken instructions.
- •Subjects must not be enrolled in a concurrent clinical trial involving an investigational pharmaceutical, nutraceutical, medical device, or behavioral treatment for TBI that could affect the outcome of this study.
结局指标
主要结局
Change in Functional Performance
时间窗: After three months of training
Between-group magnitude of change in sum time of all tasks in the Timed Instrumental Activities of Daily Living (TIADL). Higher scores indicate greater impairment in functional performance.
Change in Cognitive Function
时间窗: After three months of training
Between-group magnitude of change in composite score with the measure constructed from Rey Auditory Verbal Learning Test (RAVLT) sum of trials 1-5 (immediate verbal memory), RAVLT delayed verbal recall, the Ruff Light Trails Test (RULIT) sum of trials 2-10 (immediate visual memory), RULIT delayed recall scores, digit span (WAIS, sum of forwards, backwards, sequencing), symbol span (WMS), anti-saccades, flanker, and set-shifting (each from the EXAMINER battery).
