Cranial Electrotherapy Stimulation (CES) for Soldiers With Combat-Related Symptoms

Inclusion Criteria: * Soldiers over 18 years old or emancipated minors willing to sign an informed consent and complete all protocol requirements. * Soldiers who score 4 or greater on the visual analog scale for irritability Exclusion Criteria: * Seizure disorders. * Pregnancy. All female Soldiers will verify in the informed consent that they are not currently pregnant. Safety of stimulation has not been established during pregnancy and therefore we will exclude women who are or want to become pregnant during the course of the study. * Concomitant therapy with an investigational drug or device, or participation in an investigational drug or device study within one month prior to entering this study * Patients with a pacemaker or implanted defibrillator. The Alpha-Stim 100 may effect the operation of cardiac pacemakers (particularly demand type pacemakers) and therefore this population will be excluded from this study.
