Randomized Controlled Trial Comparative Study Clinical TrialDose effects of modafinil in sustaining wakefulness in narcolepsy patients with residual evening sleepiness.
Excessive sleepiness associated with narcolepsy lasts throughout the waking day. The authors conducted two randomized, double-blind studies to compare the efficacy of modafinil once-daily versus split doses in maintaining wakefulness throughout the day. ⋯ All modafinil dosing regimens were well tolerated. In patients who experience excessive sleepiness in the late afternoon/evening, despite satisfactory treatment earlier in the day, a split dose of modafinil may promote wakefulness throughout the waking day.

Review Comparative StudyTreatment of acute ischemic stroke: does it impact neuropsychiatric outcome?
Stroke is a leading cause of disability globally. Although neuropsychiatric symptoms are produced by stroke and adversely effect stroke outcome, it is unclear whether neuropsychiatric outcome can be improved by acute stroke treatment. ⋯ Of the 190 trials reviewed, only seven included specific measures of neuropsychiatric outcome, usually a short test of cognition or mood. Further studies are needed to determine the potential benefits of acute stroke treatment on both poststroke neuropsychiatric symptoms and the relationship between such symptoms and stroke outcome.

Comparative StudyDiagnostic criteria for postconcussional syndrome after mild to moderate traumatic brain injury.
This study evaluated the prevalence and specificity of diagnostic criteria for postconcussional syndrome (PCS) in 178 adults with mild to moderate traumatic brain injury (TBI) and 104 with extracranial trauma. Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and International Classification of Diseases (ICD-10) criteria for PCS were evaluated 3 months after injury. ⋯ Specificity to TBI was limited because PCS criteria were often fulfilled by patients with extracranial trauma. The authors conclude that further refinement of the DSM-IV and ICD-10 criteria for PCS is needed before these criteria are routinely employed.

Comparative StudyCognitive impairment associated with major depression following mild and moderate traumatic brain injury.
Traumatic brain injury (TBI) and major depression are neuropsychiatric conditions that have been associated with cognitive dysfunction. The aim of this study was to explore the relationship between major depression and cognitive impairment following mild and moderate TBI. ⋯ Subjects with major depression (28.4%), compared to those without, were found to have significantly lower scores on measures of working memory, processing speed, verbal memory and executive function. Potential mechanisms and implications for treatment are discussed.

Comparative StudyHigh-resolution brain SPECT imaging and eye movement desensitization and reprocessing in police officers with PTSD.
Eye movement desensitization and reprocessing (EMDR) has been shown to be an effective treatment for posttraumatic stress disorder (PTSD). In this study, the authors evaluated the effectiveness and physiological effects of EMDR in police officers involved with on-duty shootings and who had PTSD. ⋯ In addition, there were decreases in the left and right occipital lobe, left parietal lobe, and right precentral frontal lobe as well as significant increased perfusion in the left inferior frontal gyrus. In our study EMDR was an effective treatment for PTSD in this police officer group, showing both clinical and brain imaging changes.
