I m preparing or an appointment with a neurologist investigate th possibility of nocturnal bruxism manifested by extreme dental damage and wearing down of of the bottom teeth in particular and also breakage of one of the upper teeth, ll consequent to extensive crown and bridge work to correct the bite line. In addition to likely bruxism evidenced by nocturnal tooth grinding, appear to be scratching my head during the night causing small scabs at the roots of the hair. Could this be caused by nocturnal arousal episodes. I have been diagnosed for PTSD ad Bipolar II as a consequence of episodes that occurred during the Vietnam War.
