Do you find it hard to pay attention? Do you feel the need to move constantly during times when you shouldn’t? Do you find yourself constantly interrupting others? If these issues are ongoing and you feel that they are negatively impacting your daily life, it could be a sign of attention-deficit/hyperactivity disorder (ADHD).
ADHD is a disorder that makes it difficult for a person to pay attention and control impulsive behaviors. He or she may also be restless and almost constantly active.
ADHD is not just a childhood disorder. Although the symptoms of ADHD begin in childhood, ADHD can continue through adolescence and adulthood. Even though hyperactivity tends to improve as a child becomes a teen, problems with inattention, disorganization, and poor impulse control often continue through the teen years and into adulthood.
What causes ADHD?
Researchers at the National Institute of Mental Health (NIMH), National Institutes of Health (NIH), and across the country are studying the causes of ADHD. Current research suggests ADHD may be caused by interactions between genes and environmental or non-genetic factors. Like many other illnesses, a number of factors may contribute to ADHD such as:
Cigarette smoking, alcohol use, or drug use during pregnancy
Exposure to environmental toxins, such as high levels of lead, at a young age
Low birth weight
People with ADHD show an ongoing pattern of three different types of symptoms:
Difficulty paying attention (inattention)
Being overactive (hyperactivity)
Acting without thinking (impulsivity)
These symptoms get in the way of functioning or development. People who have ADHD have combinations of these symptoms:
Overlook or miss details, make careless mistakes in schoolwork, at work, or during other activities
Have problems sustaining attention in tasks or play, including conversations, lectures, or lengthy reading
Seem to not listen when spoken to directly
Fail to not follow through on instructions, fail to finish schoolwork, chores, or duties in the workplace, or start tasks but quickly lose focus and get easily sidetracked
Have problems organizing tasks and activities, such as doing tasks in sequence, keeping materials and belongings in order, keeping work organized, managing time, and meeting deadlines
Avoid or dislike tasks that require sustained mental effort, such as schoolwork or homework, or for teens and older adults, preparing reports, completing forms, or reviewing lengthy papers
Lose things necessary for tasks or activities, such as school supplies, pencils, books, tools, wallets, keys, paperwork, eyeglasses, and cell phones
Become easily distracted by unrelated thoughts or stimuli
Forgetful in daily activities, such as chores, errands, returning calls, and keeping appointments
Signs of hyperactivity and impulsivity may include:
Fidgeting and squirming while seated
Getting up and moving around in situations when staying seated is expected, such as in the classroom or in the office
Running or dashing around or climbing in situations where it is inappropriate, or, in teens and adults, often feeling restless
Being unable to play or engage in hobbies quietly
Being constantly in motion or “on the go,” or acting as if “driven by a motor”
Blurting out an answer before a question has been completed, finishing other people’s sentences, or speaking without waiting for a turn in conversation
Having trouble waiting his or her turn
Interrupting or intruding on others, for example in conversations, games, or activities
Showing these signs and symptoms does not necessarily mean a person has ADHD. Many other problems, like anxiety, depression, and certain types of learning disabilities, can have similar symptoms. If you are concerned about whether you or your child might have ADHD, the first step is to talk with a health care professional to find out if the symptoms fit the diagnosis. The diagnosis can be made by a mental health professional, like a psychiatrist or clinical psychologist, primary care provider, or pediatrician.
Although there is no cure for ADHD, currently available treatments may help reduce symptoms and improve functioning. ADHD is commonly treated with medication, education or training, therapy, or a combination of treatments.
For many people, ADHD medications reduce hyperactivity and impulsivity and improve their ability to focus, work, and learn. The first line of treatment for ADHD is stimulants.
Stimulants: Although it may seem unusual to treat ADHD with a medication that is considered a stimulant, it is effective. Many researchers think that stimulants are effective because the medication increases the brain chemical dopamine, which plays essential roles in thinking and attention.
Non-Stimulants: These medications take longer to start working than stimulants, but can also improve focus, attention, and impulsivity in a person with ADHD. Doctors may prescribe a non-stimulant if a person had bothersome side effects from stimulants, if a stimulant was not effective, or in combination with a stimulant to increase effectiveness. Two examples of non-stimulant medications include atomoxetine and guanfacine.
Antidepressants: Although antidepressants are not approved by the U.S. Food and Drug Administration (FDA) specifically for the treatment of ADHD, antidepressants are sometimes used to treat adults with ADHD. Older antidepressants, called tricyclics, sometimes are used because they, like stimulants, affect the brain chemicals norepinephrine and dopamine.
There are many different types and brands of these medications—all with potential benefits and side effects. Sometimes several different medications or dosages must be tried before finding the one that works for a particular person. Anyone taking medications must be monitored closely and carefully by their prescribing doctor.
