| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To determine whether the long‐term use of methylphenidate (> 3 years) increases blood pressure and causes left ventricular hypertrophy (LVH) identified by echocardiography in late adolescence (≥16 years) and young adults with ADHD. |
|
| E.2.2 | Secondary objectives of the trial |
| If the long‐term use of methylphenidate (> 3 years) increases blood pressure and causes left ventricular hypertrophy (LVH) identified by echocardiography in late adolescent (≥16 years) and young adults with ADHD, are there other factors which are involved e.g. age, sex, socioeconomic status, other medications, negative lifestyle factors, weight and familial cardiovascular risk. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
Treated Group: Patients with ADHD according to DSM-IV criteria (any subtype), based on clinical diagnosis, and confirmed by a structured interview • Aged between 15 and 25 years. • Any comorbidity is allowed. • Any comedication other than dexamphetamine, lysdexamfetamine or atomoxetine is allowed. • Treated with methylphenidate (IR or ER preparations) for 3 years or longer, continuously.
Control group: • Patients with ADHD according to DSM‐IV criteria (any subtype), based on clinical diagnosis. • Aged between 16 and 25 years. • Any comorbidity is allowed. • Any comedication is allowed. • Never been treated with methylphenidate
|
|
| E.4 | Principal exclusion criteria |
All groups: Patients who do not wish to take part in the research study (questionnaire, ambulatory blood pressure measurements and an echocardiogram) Treatment of ADHD with dexamphetamine, lysdexamfetamine or atomoxetine.
ADHD controls: Treatment with methylphenidate.
