A therapist must find the root cause and determine the type of pathological lying for treatment to be established. A pathological liar's treatment includes making an effort to not lie, record all lies, and understand why each lie was told, according to Achieve Solutions.
Pathological lying stems from other disorders or reasons such as low self-esteem, narcissism, or borderline personality disorder per Achieve Solutions. The therapist determines a root cause when the patient is open. This enables the therapist to establish a treatment plan. A therapist engages in role-playing or prescribes medications.
When the urge to tell a story arises the patient must refrain from lying to treat pathological lying. A pathological liar thinks about why he told a lie. Was the lie to gain attention, for personal pleasure, or to hide what he is truly doing? For treatment, a pathological liars notes every lie told, regardless of how small the lie is, suggests Achieve Solutions.
