What can cause pathological lying and mood swings?

Pathological lying and mood swings can stem from various psychological conditions, such as borderline personality disorder, narcissistic personality disorder, or other mood disorders. Trauma, stress, and unresolved emotional conflicts may also contribute to these behaviors. Additionally, neurobiological factors and imbalances in brain chemistry can play a role in affecting mood regulation and truthfulness. Understanding the underlying causes often requires professional evaluation and treatment.
