    Metamemory is the awareness and control of your ability to remember. This could include judging how well you remember something, detecting memory mistakes, or developing learning strategies.

  • Verbal Memory After Traumatic Brain Injury

  • Predicting Seizures In The Acute Stage Of Pediatric Traumatic Brain Injury

    Post-traumatic seizures are dangerous in the first week after a severe traumatic brain injury. Currently, the recommended guideline for a child at high risk for early post-traumatic seizures is to use an anti-epileptic drug for prevention. But, it can be difficult to predict those at risk, and there is no consensus on timing or dosage. Recent research has uncovered the most consistent risk factors ...

  • Abnormal Heart Rate and Autonomic Regulation After Mild Traumatic Brain Injury

    Posted By Scarlett Law Group || 17-May-2011

    In a recent study of mild TBI patients, distinct differences in heart rate and autonomic regulation were found between people with and without a brain injury. People with a mild TBI are more likely than uninjured people to have higher heart rates when supine. When rising from supine to standing, they were more likely than uninjured people to show lowered heart rate and inadequate cardiovagal ...

When comparing his MRI scan from two weeks after his injury to an MRI ...

  • New Cases of Depression Related to Specific Brain Injuries

    Posted By Scarlett Law Group || 12-May-2011

    New cases of depression are common after traumatic brain injury. But it is not fully understood whether the depression is directly related to a brain injury, or if it is an indirect result of negative lifestyle changes after a brain injury.
