some day back i was watching a recording of programme telecasted on CNN ,they were saying " stuttering is a neuorological condition".so there may be chances that scientist can develop some kind of medicine or pill to control/cure stammering .
their dr macguire says that stammering is not due to physcological weakness but due to anomatical problem in brain which is miscommunication between brain, speech center, mouth, thought and tongue in getting word out.
ganglia is part of brain which controls the speech .there are some other parts of brain which tell us what we want to say ,formation of word and finaly a part of brain which initiate speech we call this part as striatal.....after some test they conculed in pws striatal is bombarded by to much of dopamine(may be this the reason for stammering) and level of dopamine is directly realted with our thought, anxiety etc etc. ....
macguire and other researcher believe some anti anxiety medicine can control stammering by controling dopamin and they claim this medicine has no side effect(forgot the name of medicine) but they are still doing clinical trail...(dont want comment about side effect of medicine, accoding to me their may be some side effect which may come on picture latter )
one pws said that he experienced free flow of thought that he never before
so in shot controlling dopamin level can control our sammering but is anti anxiety pil is only way to controll dopamine..surly not, one can controll his anxiety by many way like boldly facing facing fear situation(fatest way) or by controlling thoughts which causes anxiety by practing meditation, (according to me controlling anxiety is just one benefit of meditation)
i used big word of medical science just to impress readers :-)
