Yes, ADHD can make you suicidal. ADHD is a developmental disorder that involves delays in how a person manages to control attention, emotion, and behavior.
People with attention deficit hyperactivity disorder may have an increased risk of suicide because of the higher levels of impulsivity. Impulsivity, a prominent symptom of ADHD, can drive one from suicidal thoughts to suicidal behaviors when in distress. People with ADHD are more prone to acting in dangerous or risky ways and spend less time thinking about the effects or permanence of trying to end their lives.
Additionally, people with ADHD have a hard time following instructions or keeping up with social cues. If untreated, these struggles may cause stress, anxiety, and depression. They may also increase conflict with others, leading to feelings of hopelessness, loneliness, rejection, and failure. People with ADHD tend to turn to substance use to deal with mental health issues. But this only increases the risk of suicide.
