Brief summary
Adults with Attention Deficit Hyperactivity Disorder (ADHD) have impairments in attentional subsystems of alerting and conflict monitoring. Mindfulness meditation may lead to an improvement of these deficits, and reduces symptoms of anxiety and depression. However, the studies that demonstrated these improvements did not use a control group, nor controlled the use of medication. In the present study the investigators will examine the effects of the mindfulness practices (same protocol of 8 weekly sessions used in the study that showed positive effects in this disorder) in the performance of adult patients and healthy people (with ADHD). Cognitive performance, mood, and the quality of life will be assessed by validated questionnaires before and after treatment/standby.
Interventions
BEHAVIORALActive comparator (meditation) with healthy subjects
The control group with healthy subjects that was participate in meditation (active control group)
BEHAVIORALMeditation
In the eight weeks following the first session of cognitive tests, the participants made a practice of weekly meditation group lasting 2 hours. Practices with each group (patients and active controls) occurred on different days. With regard to meditation practices were performed in a sitting posture with emphasis on daily life. Each weekly session involved meditation practices with trained professional, practical proposals for home exercise and a discussion group. Meditation compact discs (CDs)were given to participants for practices at home, which proposed activities for 5 minutes to 1 week and 2 weeks for 10 minutes 3-5, and finally 15 minutes for 6-8 weeks. After 8 weeks of treatment the second session of tests was held that involved the same tasks in session 1.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate the ADHD symptoms before to the meditation and after 8 weeks to the meditation. | change from baseline in ADHD symptoms at 8 weeks | The symptoms of inattention and hyperactivity / impulsivity were evaluated by means the Adult self-report scale (ASRS). |
| Evaluate the executive functions | 1 day | The executive functions tests were applied before to the meditation, so that to avoid learning. |
| Evaluate the mood symptoms before to the meditation and 8 weeks after to the meditation. | change from baseline in mood symptoms at 8 weeks. | The symptoms of anxiety and depression were evaluated by means of the following scales: Trait Anxiety Inventory (STAI-Trait), and Beck Depression Scale, respectively, and the visual-analog scales of mood (VAMS)and Positive and negative Affect Schedule extended (PANAS-X). |
| Evaluate the quality of life before to the meditation and 8 weeks after to the meditation. | change from baseline in quality of life at 8 weeks. | Quality of Life was evaluated by means of the Questionnaire in Adults with ADHD (AAQoL). |
| Evaluate the attention before to the meditation and 8 weeks after to the meditation. | change from baseline in attention at 8 weeks. | The scores of attention was evaluated by Continuous Performance Test (CPT) and the Attentional Network Test (ANT). |
