Adults With Persistent ADHD: Gender and Psychiatric Comorbidities-A Population-Based Longitudinal Study

Area of Science:

• Psychiatry
• Neurodevelopmental Disorders
• Epidemiology

Background:

• Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with potential long-term implications.
• Comorbid psychiatric disorders are frequently observed in individuals with ADHD, but adult persistence and associated comorbidities require further investigation.

Purpose of the Study:

• To evaluate the associations between Attention-Deficit/Hyperactivity Disorder (ADHD) and comorbid psychiatric disorders in adults.
• To examine the persistence of ADHD from childhood into adulthood and its relationship with psychiatric comorbidities.

Main Methods:

• A population-based birth cohort from Rochester, Minnesota, was utilized for participant recruitment.
• Participants included individuals with childhood ADHD (n=232) and non-ADHD controls (n=335).
• The M.I.N.I. International Neuropsychiatric Interview was administered to assess current ADHD status and psychiatric comorbidities.

Main Results:

• Among those with childhood ADHD, 49% had persistent adult ADHD.
• Adults with persistent ADHD showed a significantly higher likelihood of having 12 psychiatric comorbidities compared to controls and those with non-persistent ADHD.
• Associations remained significant or marginally significant when stratified by gender, with externalizing disorders more common in men and internalizing disorders in women.

Conclusions:

• Persistent Attention-Deficit/Hyperactivity Disorder (ADHD) in adulthood is strongly associated with an increased risk of comorbid psychiatric disorders.
• These associations are evident in both adult men and women.
• Understanding these comorbidities is crucial for comprehensive ADHD management in adults.
