Loneliness is a profound emotional and psychological state that can have far-reaching effects on mental health, especially among young people, for whom increases in depression, anxiety, self-harm, and suicidal ideation often accompany their loneliness. A recent systematic review and meta-analysis found that loneliness is more intense among young people with attention deficit hyperactivity disorder (ADHD).

Researchers analyzed the findings of 23 studies to determine how loneliness levels differed between young people (under age 25) with or without ADHD. Then, they looked at links between loneliness and mental health problems in young people with ADHD.

They found that young people with ADHD experience considerably higher levels of loneliness than those without. They also found a correlation between loneliness and various mental health problems among young people with ADHD.

ADHD is a neurobehavioral condition characterized by inattention and/or hyperactive or impulsive behavior. It affects people across the lifespan and influences aspects of their academic, occupational, and social functioning.

These findings suggest that young people with ADHD are particularly vulnerable to loneliness and the mental health problems that accompany it. Sleep deprivation can contribute to feelings of loneliness, too. Learn more in this clip featuring sleep expert Dr. Matthew Walker.
