ADHD Medtest App

Measuring the effect of ADHD treatment



One in 25 children has ADHD. ADHD is characterized by impairments in the ability to concentrate, distractibility, hyperactivity and impulsivity. Many parents find themselves considering whether or not a certain treatment has a positive effect on the ADHD symptoms of their child. Use the ADHD Medtest App to measure the effect of treatment on your child’s ADHD symptoms. Parents and teachers can use the behavior rating scales, and children can do the attention test.

ADHD Medtest App

The app has been designed to efficiently measure attention, concentration, and impulsivity, before and after medication usage, allowing for a quick and easy appraisal of the effect of medication on ADHD symptoms. The app can be used from ages 5 and up. Together with the child and parents, the prescribing physician assesses the effect of medication using the ADHD Medtest App. Children can do a 10-15 minute test using the iPad or iPhone. The test measures attention, distractibility, and impulsivity. During the test, the phone’s accelerometers measure the child’s movements. Parents rate their child’s behavior using their phone, and do so at least twice: once with and once without medication. Teachers or others can also rate the behavior. The app allows you to compare the combined scores with and without medication easily.


Treating ADHD starts with education about ADHD symptoms and involves learning how to deal with the strengths and difficulties associated with ADHD. Your doctor may suggest prescribing medication as well. Methylphenidate is often the first choice. The drug is effective for approximately 4 hours and is usually prescribed 2 or 3 times a day. It increases the ability to pay attention and reduces impulsivity and hyperactivity. Methylphenidate’s long-acting variants work 8 or 12 hours and need to be taken only once a day. The main side effects are difficulty falling asleep, decreased appetite, stomachache, and headache. Usually, the side effects go away after the first 2 weeks on the medicine, although some children have difficulty falling asleep. When methylphenidate does not work sufficiently, or gives rise to too many side effects, dexamphetamine may be prescribed. Dexamphetamine works for approximately 6 hours and is usually prescribed twice daily. It is a little stronger than methylphenidate but otherwise quite similar.

Medication for ADHD is effective in most children, approximately 4 out of 5. That means that for 1 in 5 children, medication does not work sufficiently. In practice, it can be difficult to find out whether or not medication is effective, as children show different behavior in different environments and at different moments. The ability to concentrate may be sufficient at home but not at the stimulus-rich surroundings of school. Children may seem calm at school, as problems with distractibility remain unnoticed.
