"Several years ago my life long difficulties with startles escalated to classic hyperekplexia.  After some research, my suggestions to both a geriatric psychiatrist and movement disorder specialist agreed to try Klonopin ... .5 mg twice/day.  Worked fine to decrease intensity and frequency of &quot;attacks.&quot;  I also have dystonia and as the cervical &quot;storms&quot; increased, they increased Klonopin to .5 three times a day.  Helped some but does not extinguish the disorders ... nothing will.  One just has to avoid the &quot;triggers,&quot; if possible."
