I don't know how I feel about this. It has long been known that caffeine, even in doses too low to be detected by the user, will improve these same traits......
Scientists at the Indiana University School of Medicine, Spaulding Rehabilitation Hospital/ Harvard Medical School and the University of California, San Diego, announced the results of human tests of the ADHD drug, as well as a second drug that is approved for Alzheimer's disease treatment, in a report published online by the journal Neuropsychopharmacology.
Although the clinical trial was small, involving just 32 participants, given the results it's "imperative" that additional trials with larger numbers of participants be organized to determine whether the results can be replicated, the authors said.
The study compared the results of treatment with methylphenidate, used to treat ADHD, and galantamine, approved to treat memory loss symptoms in Alzheimer's disease, with placebo in patients who had been diagnosed with post-traumatic stress disorder and/or mild traumatic brain injury, and clinically significant cognitive complaints, such as memory loss and poor attention.
In the newly reported trial results, treatment with methylphenidate was associated with significant declines in post-traumatic stress disorder symptoms and post-concussion symptoms. Also noted were significant improvements in tests of attention and the ability to process information quickly, the researchers said.
The improvements in cognitive symptoms and post-traumatic stress disorder symptoms occurred early in the 12-week treatment period and were maintained throughout the treatment, effects that far exceeded those "seen for currently marketed agents used to treat PTSD," the authors wrote.
