Adult attention-deficit/hyperactivity disorder (ADHD) is a mental health disorder that includes a combination of persistent problems, such as difficulty paying attention, hyperactivity and impulsive behavior. Adult ADHD can lead to unstable relationships, poor work or school performance, low self-esteem, and other problems.
Though it’s called adult ADHD, symptoms start in early childhood and continue into adulthood. In some cases, ADHD is not recognized or diagnosed until the person is an adult. Adult ADHD symptoms may not be as clear as ADHD symptoms in children. In adults, hyperactivity may decrease, but struggles with impulsiveness, restlessness and difficulty paying attention may continue.
Treatment for adult ADHD is similar to treatment for childhood ADHD. Adult ADHD treatment includes medications, psychological counseling (psychotherapy) and treatment for any mental health conditions that occur along with ADHD.
Some people with ADHD have fewer symptoms as they age, but some adults continue to have major symptoms that interfere with daily functioning. In adults, the main features of ADHD may include difficulty paying attention, impulsiveness and restlessness. Symptoms can range from mild to severe.
Many adults with ADHD aren’t aware they have it — they just know that everyday tasks can be a challenge. Adults with ADHD may find it difficult to focus and prioritize, leading to missed deadlines and forgotten meetings or social plans. The inability to control impulses can range from impatience waiting in line or driving in traffic to mood swings and outbursts of anger.
Adult ADHD symptoms may include:
• Disorganization and problems prioritizing
• Poor time management skills
• Problems focusing on a task
• Trouble multitasking
• Excessive activity or restlessness
• Poor planning
• Low frustration tolerance
• Frequent mood swings
• Problems following through and completing tasks
• Hot temper
• Trouble coping with stress
What’s typical behavior and what’s ADHD?
Almost everyone has some symptoms similar to ADHD at some point in their lives. If your difficulties are recent or occurred only occasionally in the past, you probably don’t have ADHD. ADHD is diagnosed only when symptoms are severe enough to cause ongoing problems in more than one area of your life. These persistent and disruptive symptoms can be traced back to early childhood.
Diagnosis of ADHD in adults can be difficult because certain ADHDsymptoms are similar to those caused by other conditions, such as anxiety or mood disorders. And many adults with ADHD also have at least one other mental health condition, such as depression or anxiety.
While the exact cause of ADHD is not clear, research efforts continue. Factors that may be involved in the development of ADHD include:
• Genetics. ADHD can run in families, and studies indicate that genes may play a role.
• Environment. Certain environmental factors also may increase risk, such as lead exposure as a child.
• Problems during development. Problems with the central nervous system at key moments in development may play a role.
Risk of ADHD may increase if:
• You have blood relatives, such as a parent or sibling, with ADHDor another mental health disorder
• Your mother smoked, drank alcohol or used drugs during pregnancy
• As a child, you were exposed to environmental toxins — such as lead, found mainly in paint and pipes in older buildings
• You were born prematurely
ADHD can make life difficult for you. ADHD has been linked to:
• Poor school or work performance
• Financial problems
• Trouble with the law
• Alcohol or other substance misuse
• Frequent car accidents or other accidents
• Unstable relationships
• Poor physical and mental health
• Poor self-image
• Suicide attempts
Although ADHD doesn’t cause other psychological or developmental problems, other disorders often occur along with ADHD and make treatment more challenging. These include:
• Mood disorders. Many adults with ADHD also have depression, bipolar disorder or another mood disorder. While mood problems aren’t necessarily due directly to ADHD, a repeated pattern of failures and frustrations due to ADHD can worsen depression.
• Anxiety disorders. Anxiety disorders occur fairly often in adults with ADHD. Anxiety disorders may cause overwhelming worry, nervousness and other symptoms. Anxiety can be made worse by the challenges and setbacks caused by ADHD.
• Other psychiatric disorders. Adults with ADHD are at increased risk of other psychiatric disorders, such as personality disorders, intermittent explosive disorder and substance use disorders.
• Learning disabilities. Adults with ADHD may score lower on academic testing than would be expected for their age, intelligence and education. Learning disabilities can include problems with understanding and communicating.
