ADHD is one of the most common neurodevelopmental disorders of childhood. Symptoms start in childhood and often last into adulthood. Identifying signs and symptoms of ADHD can help lead to a diagnosis, which is a process with several steps. Treatment can involve a combination of behavior therapy and medication.
Many children may have difficulties sitting still, waiting their turn, paying attention, being fidgety, and acting impulsively. However, children who meet diagnostic criteria for ADHD, differ in that their symptoms of hyperactivity, impulsivity, organization, and/or inattention are noticeably greater than expected for their age or developmental level. These symptoms lead to significant suffering and cause problems at home, at school or work, and in relationships. The observed symptoms are not the result of an individual being defiant or not being able to understand tasks or instructions.
A diagnosis is based on the presence of persistent symptoms that have occurred over a period of time and are noticeable over the past six months. While ADHD can be diagnosed at any age, this disorder begins in childhood. When considering the diagnosis, the symptoms must be present before the individual is 12 years old and must have caused difficulties in more than one setting. For instance, the symptoms can not only occur at home.
Inattentive refers to challenges with staying on task, focusing, and organization. For a diagnosis of this type of ADHD, six (or five for individuals who are 17 years old or older) of the following symptoms occur frequently:
Hyperactivity refers to excessive movement such as fidgeting, excessive energy, not sitting still, and being talkative. Impulsivity refers to decisions or actions taken without thinking through the consequences. For a diagnosis of this type of ADHD, six (or five for individuals who are 17 years old or older) of the following symptoms occur frequently:
This type of ADHD is diagnosed when both criteria for both inattentive and hyperactive/impulse types are met.
ADHD is typically diagnosed by mental health providers or primary care providers. A psychiatric evaluation will include a description of symptoms from the patient and caregivers, completion of scales and questionnaires by patient, caregivers and teachers, complete psychiatric and medical history, family history, and information regarding education, environment, and upbringing. It may also include a referral for medical evaluation to rule out other medical conditions.
It is important to note that several conditions can mimic ADHD such as learning disorders, mood disorders, anxiety, substance use, head injuries, thyroid conditions, and use of some medications such as steroids (Austerman, 2015). ADHD may also co-exist with other mental health conditions, such as oppositional defiant disorder or conduct disorder, anxiety disorders, and learning disorders (Austerman, 2015). Thus, a full psychiatric evaluation is very important. There are no specific blood tests or routine imaging for ADHD diagnosis. Sometimes, patients may be referred for additional psychological testing (such as neuropsychological or psychoeducational testing) or may undergo computer-based tests to assess the severity of symptoms.
Scientists have not yet identified the specific causes of ADHD. While there is growing evidence that genetics contribute to ADHD and several genes have been linked to the disorder, no specific gene or gene combination has been identified as the cause of the disorder. However, it is important to note that relatives of individuals with ADHD are often also affected. There is evidence of anatomical differences in the brains of children with ADHD in comparison to other children without the condition. For instance, children with ADHD have reduced grey and white brain matter volume and demonstrate different brain region activation during certain tasks (Pliszka, 2007). Further studies have indicated that the frontal lobes, caudate nucleus, and cerebellar vermis of the brain are affected in ADHD (Tripp & Wickens, 2009). Several non-genetic factors have also been linked to the disorder such as low birth weight, premature birth, exposure to toxins (alcohol, smoking, lead, etc.) during pregnancy, and extreme stress during pregnancy.
ADHD treatment usually encompasses a combination of therapy and medication intervention. In preschool-age and younger children, the recommended first-line approach includes behavioral strategies in the form of parent management training and school intervention. Parent-Child Interaction Therapy (PCIT) is an evidence-based therapy modality to help young children with ADHD and oppositional defiant disorder.
According to current guidelines, psychostimulants (amphetamines and methylphenidate) are first-line pharmacological treatments for the management of ADHD (Pliszka, 2007). In preschool-aged patients with ADHD, amphetamines are the only FDA-approved medication, although guidelines suggest that methylphenidate rather than amphetamines may be helpful if behavioral interventions prove insufficient. Alpha agonists (clonidine and guanfacine) and the selective norepinephrine reuptake inhibitor, atomoxetine, are the other FDA-approved options for treating ADHD. There are newer FDA-approved medications for ADHD treatment, including Jornay (methylphenidate extended-release) which is taken at night and starts the medication effect the next morning, Xelstrym (dextroamphetamine) which is an amphetamine patch, Qelbree (viloxazine) which is a non-stimulant, Adhansia (methylphenidate hydrochloride), Dyanavel (amphetamine extended-release oral suspension), Mydayis (mixed salts amphetamine product), and Cotempla (methylphenidate extended-release orally disintegrating tablets).
Many children and families can alternate between various medication options depending on the efficacy of treatment and tolerability of the medication. The goal of treatment is to improve symptoms to restore functioning at home and at school.
Teachers and school staff can provide parents and doctors with information to help evaluate behavior and learning problems and can assist with behavioral training. However, school staff cannot diagnose ADHD, make decisions about treatment or require that a student take medication to attend school. Only parents and guardians can make those decisions with the child’s health care clinician.
Students whose ADHD impairs their learning may qualify for special education under the Individuals with Disabilities Education Act or for a Section 504 plan (for children who do not require special education) under the Rehabilitation Act of 1973. Children with ADHD can benefit from study skills instruction, changes to the classroom setup, alternative teaching techniques and a modified curriculum.
Many children diagnosed with ADHD will continue to meet criteria for the disorder later in life and may show impairments requiring ongoing treatment (Pliszka, 2007). However, sometimes a diagnosis of ADHD is missed during childhood. Many adults with ADHD do not realize they have the disorder. A comprehensive evaluation typically includes a review of past and current symptoms, a medical exam and history, and use of adult rating scales or checklists. Adults with ADHD are treated with medication, psychotherapy or a combination. Behavior management strategies, such as ways to minimize distractions and increase structure and organization, and support from immediate family members can also be helpful.
ADHD is a protected disability under the Rehabilitation Act of 1973 and the Americans with Disabilities Act (ADA). This means that institutions receiving federal funding cannot discriminate against those with disabilities. Individuals whose symptoms of ADHD cause impairment in the work setting may qualify for reasonable work accommodations under ADA.
Attention-deficit/hyperactivity disorder (ADHD) is a condition that affects brain development, causing hyperactivity, impulsive behavior or inattention. This condition starts in childhood, and many children — but not all — grow out of it. ADHD in adults can affect your work performance, social relationships and more.
While this condition can be disruptive, it’s also very treatable. There are many medication options and other ways to treat it. It’s even possible to turn this condition’s effects into advantages that can help you in the workplace and your personal life. If you think you have ADHD, getting diagnosed can help. With treatment, it’s possible to harness the effects and turn them into tools for success.
