Traumatic Brain Damage clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Detecting Malingering Detection Using Eye Movements and Response Time (MDER)

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Performance Validity Tests (PVTs) are widely used for the detection of sub-optimal effort and malingering in neuropsychological assessments. Threats to their validity however likely to intensify with time (e.g., information available on the web or from legal representatives) and may lead to a decline in their ability to differentiate between malingerers and non-malingerers. Eye movements and response time (RT) are less obvious outcome measures and under less conscious control than more conventional PVT indices (e.g., accuracy). They are therefore promising measures that can aid in detecting malingering when used in conjunction with more conventional PVT indices. The Word Memory Test (WMT) is a widely used PVT in neuropsychological evaluations. As part of the proposed study, TBI patients, chronic pain patients and healthy adults (60 in each group) will be randomly divided to one of two conditions; optimal effort or sub-optimal effort (participants will be asked to play a TBI patient who wishes to present himself as having cognitive deficits or exaggerate existing cognitive deficits). The proposed study will improve the WMT's efficacy in detection of sub-optimal effort in neuropsychological evaluations and therefore protect its validity from future threats. In addition, the proposed study will provide us with better understanding of the effect of TBI on eye movements and RTs in general.
