Behind the lies
Sometimes the environment in which someone grew up in can plant a seed for future pathological lying. It is common for children to lie, but for those forced to lie in order to avoid abuse or who lie out of fear, it can develop into something more as a child grows older. Other disorders that may have pathological lying as a symptom include addiction, bipolar disorder, attention deficit hyperactivity disorder, dissociative identity disorder and antisocial personality disorder (or sociopathy).
While pathological liars are capable of leading functional lives, pathological lying has severely damaging effects on the relationships of the pathological liar and the people who surround her. Spouses or friends of pathological liars often end up being ashamed to be around the pathological liar, especially in other company or in the workplace. Pathological liars are at risk of being fired from their job, being alienated from peers and losing friends. Some may even face criminal problems and trouble with the law.
