Doctors in Amsterdam say that a drug commonly associated with drowsiness has given a sternly brain - injure military man brief periods of limpidity . In a late case report , they key how a single dose of the drug zolpidem — more familiarly bonk by the brand name name Ambien — can temporarily restore the military personnel ’s power to speak and walk . Sadly , the effect last only about two time of day , but the man ’s case may provide perceptivity into how the wit can be damaged by stroke and other trauma .
accord to the case report , publishedin the journal Cortex last month , the 37 - twelvemonth - erstwhile valet de chambre had suffer a tragical brain injury at age 29 . He had choked on a piece of meat , which trim off atomic number 8 to his brain long enough that it caused stern , lasting damage to his neurologic use . Though he bear witness some convalescence ab initio and hold a level of awareness , he presently stopped being able-bodied to move severally , talk , or stay awake for very long . For the next eight years , the man ’s precondition remained the same , and he needed round - the - clock breast feeding tending and a eating thermionic tube to stay awake .
While zolpidem is most often used as a sedative drug , evidence has been building that it can sometimes have aparadoxical effect , make alertness in some people , includingthosewith certain neurological disorder that leave them in a coma - like commonwealth . Dr. decide to give the Isle of Man a single , relatively gamey dose of the drug . Within 20 minutes , he became able-bodied to talk . He then spoke to his father over the headphone for the first time in years , and , with some help , even grapple to walk again . He did have amnesia of the kick the bucket incident and the three year before it , as well as some earshot problems , but otherwise , he was upbeat and zippy , even asking for loyal food at one point .

Unfortunately , the miracle recovery only lasted about an hr before he bit by bit returned to his baseline level of function . When he was impart repeat dose of zolpidem throughout the Clarence Shepard Day Jr. , the periods of normalcy grew more shortly - lasting each time , until the drug stopped working at all and even had a sedative gist on him . Eventually , doctor figured out that the zolpidem was most effective — hold out about 30 to 60 minutes per dose before fading off over the next hour — when he had n’t take it in the old two to three weeks . Because of this , he now receives the drug only for special social function , such as family visit or dental fitting .
Despite the elusiveness of a long - full term cure for the gentleman ’s experimental condition , his doctors still wanted to realize exactly how zolpidem was capable of induce such an awe-inspiring , if brief , turnaround . So they meditate his brain , via EEG and MRI , before and after he take the drug . Their findings hint that zolpidem , which works by boosting the gist of a key repressing neurotransmitter called GABA , is tranquillise down persona of the man ’s brainiac that became hyperactive stake - injury , while also increasing layer of mastermind wave bodily function linked to vigilance .
“ If you could compare the function of the brain , as it were , to a large string orchestra . In our patient , the first violin take on so loud that they swim out the other members of the twine orchestra and people can no longer hear each other . Zolpidem ensures that these first violins bet more ‘ pianissimo , ’ so that everyone plays back within prison term , ” lead generator Hisse Arnts , a aesculapian resident and neuroscience researcher at the VU University Medical Center Amsterdam , toldIFLScience .
Because this is only a single patient , and paper of zolpidem doctor awareness in similar patient are rare , there ’s still a lot left to be learned about the drug ’s effects on the brain outside of its accepted purpose as a quietus aid . But ideally , this research could extend to advances in apprehension and perhaps one day repairing the unique sort of mastermind scathe that ’s responsible for the man ’s status . One possible succeeding step , the author speculated , is to practice existing therapies like deep mind arousal to balance out the wit ’s overactivity for longer periods of sentence than zolpidem is capable of doing .
