Attention Deficit Hyperactivity Disorder
• A neurodevelopmental disorder characterized by the core symptoms of hyperactivity, impulsivity, and/or inattention
• Three types– Predominantly inattentive type– Predominantly hyperactive/impulsive type– Combined type
• 3-10 percent of children and teenagers• Male to female ratio of 3:1• Related to impairments in Executive Functioning

Attention Deficit Hyperactivity Disorder

Treatment of ADHD• Behavioral Interventions• Medications
– Stimulants• Methylphenidate: Concerta, Metadate, Ritalin, Daytrana, Focalin• Amphetamine: Adderall, Vyvanse, Dexedrine
– Non-stimulants• Atomexetine (Strattera)• Alpha-2 adrenergic receptor agonists: guanfacine (Tenex, Intuniv),
clonidine (Kapvay)

Significance of ADHD in the Concussed Athlete
• Children and teens with ADHD are at higher risk for injuries (including concussion) than children and teens without ADHD
• ADHD is one of several conditions that predispose concussed athletes to a prolonged recovery
• Many post-concussive symptoms are similar to the impairments in Executive Functioning associated with ADHD

Management of Concussion
• Pre-participation assessment• On-field or sideline evaluation• Evaluation in ER or physician’s office• Management of post-concussive
symptoms• Graduated return to play protocol
ghs.org
ADHD and Management of Concussion
• Pre-participation assessment– Pre-participation history and physical– Concussive history– Baseline Neuropsychological Testing– Baseline Symptoms
ghs.org
Baseline Neuropsycholigical Testing
• Baseline testing allows for comparison of the post-concussed athlete’s performance to his pre-injury performance rather than to normative data
• This is particularly important for the athlete with ADHD– Normative data generation often excludes individuals
with neurodevelopmental differences such as ADHD– Depending on the test, individuals with ADHD may
perform differently than individuals without ADHD

ADHD and Neuropsych Testing
Computerized Neuropsychological Screening of Adolescents with ADHD

ADHD and Neuropsych Testing
• Study compared the performance of 38 adolescents with self-reported ADHD and 38 healthy students on ImPACT, a computerized neuropsychological screening battery
• The students were matched for age, education, gender, and history of head injury
• ImPACT generates composite scores for five areas: Verbal Memory, Visual Memory, Processing Speed, Reaction Time, and Impulse Control
• Adolescents with self-reported ADHD performed more poorly on the Visual Memory Composite (p<.006), the Processing Speed Composite (p<.004) and the Impulse Control Composite (p<.001)

ADHD and Neuropsych TestingA 2008 study by the same group compared 41 student
athletes with academic problems (either in special education or had repeated a grade) with 41 randomly selected controls.
Results revealed significantly worse scores for students with academic problems on Verbal Memory and Processing Speed composites.
The students with academic problems also reported more symptomatology on the Post-Concussion Scale

ADHD and Management of Concussion
• Evaluation in [ER or] physician’s office– Team approach is ideal– Medical evaluation– Neuropsychological testing

Neuropsych Testing and the Concussed Adolescent Athlete
• From the Zurich Consensus Statement: “If cognitive testing is performed [in the child and
adolescent athlete] then it must be developmentally sensitive until late teen years due to the ongoing cognitive maturation that occurs during this period which, in turn, makes the utility of comparison to either the person’s own baseline performance or to population norms limited. In this age group it is more important to consider the use of trained neuropsy-chologists to interpret assessment data, particularly in children with learning disorders and/or ADHD who may need more sophisticated assessment.”

Post-Concussion Neuropsych Testing
• Within 24-48 hours after the concussion• Administered by an individual trained in
administering the instrument being used• Consultation with a neuropsychologist for
interpretation of results• Periodic testing until performance returns
to baseline

ADHD and Management of Concussion
• Management of post-concussive symptoms

Management of Post-Concussive Symptoms
• Individualized Treatment Program to Address:– Cognitive Symptoms– Physical Symptoms– Sleep Problems– Fatigue Symptoms– Affective Symptoms
ghs.org
Concussion and ADHD Medications
• Some Controversy No good evidence• Stimulants and Strattera associated with slight
rise in blood pressure and heart rate– In treatment of concussion, trying to keep athlete at
rest trying to AVOID raising blood pressure and heart rate
– Increased risk of cerebral vascular accident in the area of injury?
• Alpha-2 adrenergic receptor agonists associated with decreased blood pressure and heart rate

Concussion and ADHD Medications
Dr. Beard: Stop a stimulant or Strattera until headache and neurological symptoms resolve and neuropsychological testing approaching baseline. Continue alpha-2 adrenergic agonists.

Summary Points• ADHD is a common diagnosis in children and
adolescents• Athletes with ADHD may be more susceptible to
suffering a concussive injury and may have protracted recovery time with concussion
• Baseline Neuropsychological testing is important for all athletes but particularly important for athletes with ADHD
• There is no consensus recommendation on when a concussed athlete with ADHD should restart medications
