Which personality disorder is characterized by instability, irritability, and impulsive anger?

• A. Narcissistic Personality Disorder
• B. Borderline Personality Disorder
• C. Dependent Personality Disorder
• D. Paranoid Personality Disorder

Answer: (B)

Borderline Personality Disorder is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, and emotions, along with marked impulsivity. Individuals with this disorder often experience intense fluctuations in their mood, leading to feelings of irritability and impulsive anger. This instability can cause significant problems in maintaining relationships and can lead to impulsive decisions that may be harmful.

The emotional dysregulation seen in this disorder often results in a reactive nature, meaning that individuals may respond with anger or irritability to perceived slights or abandonment. Additionally, they may have difficulty managing their anger and may display intense emotions that seem disproportionate to the situation.

When considering the other disorders, Narcissistic Personality Disorder generally involves a pattern of grandiosity and a need for admiration, with a lack of empathy, rather than instability in emotions and relationships. Dependent Personality Disorder is characterized by a pervasive and excessive need to be taken care of, leading to submissive behavior and fears of separation. Paranoid Personality Disorder involves a pervasive distrust and suspicion of others, focusing less on emotional instability and more on interpersonal mistrust. Thus, Borderline Personality Disorder is uniquely characterized by the combination of instability, irritability, and impulsive anger.
