5. Serious depression can generally be controlled by medication or professional counseling, so counseling or treatment for depression alone should not affect a person's security clearance. It is not the type of illness that is likely to trigger impulsive or high-risk behavior that would be a security concern.
Depression could become a security issue if it is accompanied by other problems, especially occasional periods of mania (extreme excitability or irritability). Mania may cause poor judgment, increased talkativeness and compulsive behavior, all of which may be security concerns.
More detailed information on depression and several other types of common personal problems is available in titled Understanding and Helping with Personal Problems.
