ADHD in adolescents with borderline personality disorder

Area of Science:

• Psychiatry
• Developmental Psychology
• Clinical Psychology

Background:

• Borderline Personality Disorder (BPD) and Attention Deficit Hyperactivity Disorder (ADHD) are frequently comorbid in adolescents.
• Understanding the impact of comorbid ADHD on BPD presentation is crucial for effective treatment.

Purpose of the Study:

• To determine the prevalence of ADHD in adolescents diagnosed with BPD.
• To investigate how comorbid ADHD affects the clinical presentation of BPD in adolescents.
• To identify specific impulsivity characteristics in adolescents with comorbid BPD and ADHD.

Main Methods:

• A sample of 85 adolescents with DSM-IV BPD was assessed for comorbid ADHD.
• Axis I and Axis II disorders were diagnosed using the K-SADS-PL and SIDP-IV, respectively.
• The Barratt Impulsiveness Scale (BIS-11) was used to measure impulsivity.

Main Results:

• 11% of adolescents with BPD had a current ADHD diagnosis.
• Adolescents with BPD and ADHD showed a higher prevalence of disruptive disorders.
• Attentional/cognitive impulsivity scores were significantly associated with ADHD in the BPD sample.

Conclusions:

• Comorbid ADHD significantly influences the clinical presentation of adolescents with BPD.
• ADHD in BPD adolescents is associated with increased disruptive disorders and attentional/cognitive impulsivity.
• Specific interventions are recommended for BPD adolescents with comorbid ADHD, addressing potential persistent childhood inhibitory system impairments.
