Completed suicide, ideation and attempt in attention deficit hyperactivity disorder

Area of Science:

• Psychiatry
• Neuroscience
• Public Health

Background:

• Attention deficit hyperactivity disorder (ADHD) and suicidal behavior are prevalent conditions associated with substantial morbidity.
• Previous research has focused on completed suicide in ADHD, leaving other suicidal behaviors under-examined.

Purpose of the Study:

• To comprehensively review the existing literature on the relationship between ADHD and various domains of suicidal behavior, including ideation and attempts.
• To synthesize findings on the prevalence of suicidality in individuals diagnosed with ADHD.

Main Methods:

• A systematic literature search was conducted across major databases (MEDLINE, EMBASE, PSYCHINFO) using keywords related to ADHD and suicidality.
• Both electronic and manual search methods were employed to identify relevant studies.

Main Results:

• Twenty-five studies indicated a significant association between ADHD and suicidal behavior, with ADHD individuals more frequently appearing in suicidal groups.
• Suicidal attempts and ideation were more prevalent in individuals with prediagnosed ADHD compared to controls.
• Comorbid conditions, such as delinquency and substance misuse, significantly influenced the observed relationship.

Conclusions:

• A clear positive relationship exists between ADHD and an increased risk of self-harm.
• Further research is recommended for younger populations and those without comorbid conditions.
• Thorough risk assessment for suicidality is crucial for individuals diagnosed with ADHD.
