Testimony by

House Democratic Policy Committee’s Public Hearing on the Use of Ritalin

Presented December 14, 1999 and Revised 2005

Issues

  • Definitions of ADHD
  • Associated conditions
  • Treatment issues

 

  • ADHD issues in adults

 

Is this a marketing scheme to sell Ritalin?

  • No, the use and effectiveness of Ritalin is well established.
  • Ritalin is referenced in 1157 studies in medical journals from 1960 to 1999 and the evidence overwhelmingly supports the therapeutic benefits.
  • About 100 years ago Dr. Still, a pediatrician, defined the disorder.

 

  • Original symptoms included hyperactivity, learning problems, inattention and conduct problems.

 

Is ADD/ADHD just new name for old-fashioned hyperactivity?

  • The name is not as important as the key concept of inattention.
  • Many names are associated with this problem of inattention.
  • Minimal Brain Dysfunction (MBD) was an early name.
  • Others include Hyperactive Child Syndrome
  • Attention Deficit Disorder (ADD) was introduced in 1980

 

  • Attention Deficit Hyperactivity Disorder (ADHD) since 1994

 

Does everyone have ADD?

  • No, a longstanding dysfunctional pattern is necessary.
  • Symptoms or features must be distinguished from a life long pattern before 7 years old.
  • Exuberance is different from symptoms way beyond average and causing dysfunction in life.
  • Using standard rating scales such as Conners or others is necessary for assessment.

 

  • Rule out other disorders that can cause similar symptoms

 

What are the criteria?

Inattention

 

  • Careless mistakes
  • Not listen

 

  • Fail to complete tasks

 

Impulsivity

  • Frequently interrupts

 

  • Shouts out answers

 

Hyperactivity

 

  • Fidgeting
  • Out of seat

 

  • Excessive talking

 

Is the disorder mostly in boys?

  • Yes, boys are often inattentive and hyperactive. Girls do have the disorder but are usually not hyperactive or a conduct problem.
  • Girls are mistakenly called lazy, slow or spacey.

 

  • Women and girls are often misdiagnosed as anxious or depressed.

 

Will they outgrow it?

 

  • Yes and no
  • 70% persist from childhood to adolescence in some form.
  • 30-40% of grownup ADHD children do well.
  • 30-50% have persistent symptoms as adults.
  • 10-20% have significant impairment and disability.

 

  • 80-90% do not need medication as adults.

 

Do they just need to try harder?

  • Worst advice is to try harder as symptoms increase.
  • Best strategy to try “different” and find new ways to do things.
  • Brain imaging shows areas are inhibited by increased effort.

 

  • Brain imaging demonstrates abnormal anatomy and physiology in ADHD as in other disorders, such as the medical abnormalities in diabetes or asthma.

 

Is this disorder overdiagnosed?

  • It is underdiagnosed especially in girls.
  • 5-12% of all school-aged children have the disorder.
  • Less than 1 in 8 (about 12%) are treated with stimulant medication.

 

  • Adults get even less treatment, yet 2-5% or more have symptoms.

 

Caused by poor parenting or teachers?

  • No, it is physically based.
  • It is a genetic or developmental disorder.

 

  • Parents will best not search for external cause, but they can find external solutions in dealing differently to find solutions to problems.

 

Do they often abuse stimulants like Ritalin?

  • No, the problem is with they are not taking medication.
  • ADHD boys treated with medication are 84% less likely to develop a substance abuse disorder than those not treated.
  • Medication is safe, effective and has little abuse potential in prescribed doses.
  • Adolescents should be monitored for abuse and a count kept of their medication.

  • Fewer than half of children receive the services that their parents think they need.

 

  • Many with diagnosed ADHD receive no treatment.

 

Treatment: Psychopharmacology (Stimulants)

  • Methylphenidate (Ritalin) and longer acting (Concerta and Metadate)
  • Dextroamphetamine (Dexedrine)

  • 70% of children respond to the second medication.

 

  • Always try at least two medications sequentially.

 

Side Effects compared to cognitive and behavioral performance

  • Side effects gradually increase with dose and become a problem with cognition and emotions if the beneficial dosage is exceeded.

 

What should improve with stimulants?

Summary

  • Ritalin and similar medicines are safe and effective when used appropriately as part of a comprehensive treatment plan including multimodal treatment.
  • Attention Deficit Hyperactivity Disorder is a diagnosable disorder in medical practice and assessment requires information from parents and teachers.

 

  • Proper evaluation includes assessing for other possible problems and associated conditions.
