Desoxyn

I really see a difference in my grades. Without it, I don't think about things. I can't pay attention."

--Christy Rade, 16, Des Moines, Iowa, commenting in the Aug. 26, 1996, Des Moines Register on her treatment for attention-deficit/hyperactivity disorder (ADHD) with Ritalin, the brand name for the stimulant medicine methylphenidate.

"Teens Learn Dangers of Pitalin Use; 19-Year-Old Man Dies After Snorting Stimulant at Party "

--a headline in the April 24, 1995, Poanoke Times & World News, Roanoke, Va.

If, like Christy Rade, you're taking stimulant medicine for ADHD, you are not alone. In mid-1995, about 1.5 million school-age youngsters did so, reported Daniel Safer, M.D., and colleagues in Pediatrics, December 1996.

But, as the Virginia headline points out, abuse of this medicine can be deadly.

In ADHD, brain areas ruling attention and inhibition don't work very well. Most children with ADHD are inattentive, impulsive and hyperactive. In teen-agers, the hyperactivity often quiets to a restlessness. For some, paying attention is their biggest problem. Others are mainly impulsive and hyperactive.

The Food and Drug Administration has approved several stimulant medicines for treating ADHD: methylphenidate (Ritalin and generics), dextroamphetamine (Dexedrine and generics), methamphetamine (Desoxyn), and an amphetamine-dextroamphetamine combination (Adderall). FDA recently restricted another approved stimulant, pemoline (Cylert), to secondary use, as it can cause liver failure.

The drugs stimulate the central nervous system, but no one knows exactly how they work in treating ADHD.

"Stimulants have been used to treat ADHD for over three decades," says Nicholas Reuter, FDA associate director for international and domestic drug control affairs. "And the amount used has increased steadily during that period. Methylphenidate is the most widely used."

Not everyone with ADHD requires or responds to stimulant treatment.

Risk of Abuse

Because stimulant medicines have a high potential for abuse, the U.S. Drug Enforcement Administration has placed stringent controls on their manufacture, distribution and prescription. For example, DEA requires special licenses for these activities, and prescription refills aren't allowed. States may impose further regulation, like limiting the number of dosage units per prescription.

DEA has repeatedly urged greater caution in use of these drugs, especially in light of their abuse among adolescents and young adults.

Ritalin's manufacturer, Ciba-Geigy Corp., began a campaign in March 1996 to reduce abuse. In nationwide mailings to doctors and pharmacists, the firm called attention to the risk of abuse and cautioned doctors to be especially careful in diagnosing ADHD. Enclosed were behavior rating scales for doctors to use and handouts for patients, parents and school nurses.

Taken properly, Ritalin in and of itself is not addictive, says Wendy Sharp, M.S.W., a social worker and researcher at the National Institute of Mental Health's child psychiatry branch. So people with ADHD do not get addicted to their stimulant medicine at treatment dosages, she says. "There have been unfortunate cases reported in the press, however, of teenagers who have taken Ritalin from other kids and snorted it, like cocaine."

According to Reuter, "Although methylphenidate production and availability have increased dramatically since 1990, national drug abuse surveys indicate that abuse level and associated public health consequences remain below that of other stimulant medicines such as cocaine, amphetamine and methamphetamine."

Patricia Quinn, M.D., a developmental pediatrician in Washington, D.C., and author of many books on ADHD, adds, "There's actually less substance abuse in people diagnosed with attention deficit disorder who take medication and do well than in the general population. Adolescents I've worked with are trying to straighten out what's going on."

Diagnosing Difficulties

About 30 percent of young people with ADHD aren't diagnosed until middle school or later, says Quinn. These students are very bright, she says. "The more intelligent you are, the better you cope--until stressors in the environment outpace your ability to cope. Maybe your disorder becomes a problem in high school when you have only lecture classes, or in college when you have to do everything for yourself and go to class, too."

By the time someone with undiagnosed ADHD gets to middle school or high school, the main complaint is classroom underachievement rather than hyperactivity or distractibility, Quinn says. Some people shorten the name to ADD when it affects older people. "But you shouldn't assume that everyone who is underachieving has ADHD."

And, not everyone with attention difficulty has ADHD.

For example, when Linda Smith (not her real name) was 16, she had extreme difficulty concentrating. ADHD was suspected. Thorough examination, however, revealed the culprits were anxiety, depression and a sleep disorder, which are improving under a treatment plan that includes medicines and counseling.

Narrowing a diagnosis to ADHD requires more than a single visit to the doctor. Substantial detective work by the doctor involves talking not only to the patient, but also to the parents and to nurses and teachers at the patient's various schools.

"I ask to see all report cards from kindergarten on," Quinn says. "Teachers usually comment, `He would do so much better if he could only pay attention.' One mother said of her son in high school, `One day in first grade, he came home without shoes. He didn't know where he put them.' kids with this disorder lose their jackets, shoes. So he had symptoms early on."

There is no biological test for ADHD. Doctors base their diagnosis on guidelines set by the American Psychiatric Association. (See "Diagnostic Guidelines.")

Deciding to Use Stimulants

Stimulant treatment begins as a "trial," so you and your parents should tell the doctor regularly about improvements, such as handling school tasks better, and any side effects. The most common side effects are nervousness, sleep difficulty, and appetite loss. Less common are skin rash, nausea, dizziness, headache, weight loss, and blood pressure changes. Immediately report such serious effects as confusion, breathing difficulty, sweating, vomiting, and muscle twitches, which may signal too high a dose.

With this information and further examination, the doctor can determine the most effective dose that causes no, or only tolerable, side effects.

Patients who need stimulant medicine only for paying attention may not need it at all during weekends and summer vacations. If their difficult subjects are in the morning, a morning dose may be enough most days. Other patients need stimulant medicine much more often.

Stimulants are not for everyone with ADHD. For example, they shouldn't be used in someone with marked agitation, a twitching known as a tic, or the eye disorder glaucoma.

And like all medicine, stimulants pose risks. Whether to use stimulants is a case-by-case decision based on how the benefit stacks up against the risk.

In January 1996, FDA announced that in studies of rodents given methylphenidate, the drug produced a "weak signal" for the potential to cause liver cancer. The cancer occurred in male mice but not in female mice or rats. At FDA's request, Ciba-Geigy informed doctors and, along with other methylphenidate manufacturers, added the findings to their drugs' labeling.

Accompanying health problems like depression may require other medicines or psychotherapy.

"Individual therapy for ADHD may not be helpful," Sharp says. "Probably the most beneficial treatment for ADHD involves the entire family system, and behavior management is usually a large part of this treatment."

Some people have linked ADHD to sugar and food or color additives. "Research in this area has raised questions and contributes to understanding," says Catherine Bailey, an FDA science policy analyst. "But the idea that individual food substances cause ADHD is unproven. Still, if people want to avoid substances they perceive as problems, they should be sure to read food labels."

Moving Forward

Scientists don't know exactly what causes ADHD, but it tends to affect several in a family. When an identical twin has ADHD, the other usually does, too. Sharp had recruited twins for research to help clarify this.

While more males than females have ADHD, the gender gap is narrowing. Males taking medicine for the disorder outnumbered females 10 to 1 in 1985 but only 5 to 1 in 1995, the authors of the 1996 Pediatrics article stated.

Probably the hardest part of having ADHD is accepting the diagnosis, Quinn says. She stresses the importance of looking at everything else that's good in your life.

"The disorder is part of who you are and, yes, you have to control it," she says. "But it doesn't define you. It's okay to have attention disorder, so long as you know what to do about it."

RELATED ARTICLE: Helping Yourself

The first step toward dealing successfully with ADHD is to learn as much as you can about the disorder, the pros and cons of stimulant treatment, and strategies for self-help.

If you have ADHD, self-help skills can be critical to your success in high school and college, and later on with your career. In her book Adolescents and ADD, Gaining the Advantage, developmental pediatrician Patricia Quinn, M.D., advises, "Set realistic goals. Be honest about your strengths and weaknesses." These tips from her book may help.

Taking Responsibility

Talk to the school nurse.

* Bring up your concerns.

* Ask if students with ADHD meet to share ideas. If not, ask how to start a group.

* Ask the nurse to help your teachers understand your diagnosis and provide classroom support, such as more time for tests and a front seat away from distractions. People with disabilities or certain impairments are entitled to free, appropriate public education under the Individuals with Disabilities Education Act of 1990, Section 504 of the Rehabilitation Act of 1972, and the Americans with Disabilities Act of 1990. If your ADHD isn't being accommodated under these laws, ask the school nurse how to find out if it can be.

Be careful taking medicine.

* Ask about your school's policy on taking medicines at school.

* When parents deliver your medicine, be sure the prescription label lists your name, diagnosis, medicine name, dose, and, especially, when to take it.

* Until taking doses on time gets routine, make notes to yourself or set your watch alarm.

* To prevent mix-ups, always tell the person giving you the medicine your full name, see that the bottle is yours, and make sure you get the correct number of tablets.

* Report side effects to your parents or the nurse.

* Never "help out" someone else by sharing your medicine.

Improving School Work

Manage note-taking.

* Write on every other line to leave room for ideas you might add later.

* Leave out unimportant words, like "the" and "an."

* List some abbreviations of your own at the front of your notebook for reference.

* Ask a friend to take notes over carbon paper to provide a copy for you.

* Ask teachers to let you have a copy of their notes.

* Make an audio-cassette recording of lectures, especially before tests.

Understand what you read.

* Read while you are fresh.

* Decide what you're looking for. Then skim the material, noting pictures and graphs and reading the headings and bold print.

* List unfamiliar words, then look them up. Get help if you don't understand a meaning.

* Read assigned questions before the material. Then write answers as you read along.

* Highlight or underline important information on your study sheets.

* Read the material again.

Improve written assignments.

* Use a computer with a spell-check. Writing on a computer can also help you organize your thoughts.

* To check spelling without a computer, start at the bottom of the page and move up.

Improve math assignments.

* If you start to feel lost in a unit, tell your teacher, advisor or tutor immediately, as each new math concept builds on what you've already learned.

* Leave space between examples. Line up the numbers in columns carefully.

* Check each math solution before handing it in, especially on tests.

* Practice math in the summer with worksheets or summer school.

Study smarter.

* Study with a partner.

* Use your textbook's headings and subheadings for a study outline.

* Put important information on cards or audiotape for reviewing.

* Organize your notes and worksheets by topic. Study some each night.

* Allow two nights for review before a test.

* Get plenty of sleep the night before a test.

* If you get anxious when you can't answer a test question, stop and take deep breaths. Then jot down some facts you do know, which may trigger the answer.

* Discuss your school routine and grades with your advisor weekly or even daily.
