Attention Deficit/Hyperactivity Disorder Symptoms

  • Symptoms

    ADHD is characterized by inattentive, hyperactive, or impulsive behavior that begins during childhood. ADHD is characteristically diagnosed in children under the age of seven, although the disorder can be present in adolescents and adults as well. Individuals with ADHD often seem to be disorganized or preoccupied. They may be poor listeners, and frequently change the subject or become distracted by unimportant interruptions. Individuals with ADHD may appear to be impatient, interrupting others frequently, or blurting out tactless comments. Some impulsive people engage in high-risk sports or other activities. While similar symptoms can occur in normal children and adults, people with ADHD show a persistent pattern that is more frequent and more severe than that of others in the same age group.

    Some people with ADHD have mostly inattentive symptoms, while others exhibit mostly hyperactive and impulsive behavior. Most people with ADHD have features of both subtypes Table 01. Inattention may manifest itself as carelessness at work or at home, or difficulty completing projects. Individuals with ADHD often seem to be disorganized or preoccupied.

    Hyperactivity can manifest as fidgetiness or an inability to engage in tasks or leisure activities that require a person to sit still. People with these symptoms often seem to be “on the go.” Hyperactive people sometimes describe having accelerated or multiple thoughts at the same time.

    Table 1.  Symptoms of ADHD by Subtype

    Inattentive Hyperactive/impulsive
    Fails to pay close attention to details or makes careless mistakes Fidgets with hands or feet or squirms in seat
    Has difficulty sustaining attention Leaves seat in situations where remaining seated is expected
    Does not seem to listen Runs about or climbs excessively (in adults, may be limited to feelings of restlessness)
    Does not follow through on instructions and fails to finish tasks Has difficulty paying attention or engaging in leisure activities quietly
    Has difficulty organizing tasks and activities ?On the go? or acts as if ?driven by a motor?
    Avoids or dislikes tasks that require sustained mental effort Talks excessively
    Loses things necessary for tasks or activities Blurts out answers before questions completed (impulsivity)
    Easily distracted by extraneous stimuli Has problems waiting turns (impulsivity)
    Forgetful in daily activities Interrupts or intrudes on others (impulsivity)

    Other troubling features are commonly seen in individuals with ADHD Table 02. Possibly as a result of frequently being “in trouble” or regarded as lazy, many people with ADHD have low self-esteem. They may have a low tolerance for frustration, and have frequent temper outbursts and mood changes. Some very impulsive people become “class clowns.” More troubling consequences of ADHD include possible drug abuse and conduct disorder, often involving anti-social behavior and skirmishes with the law.
