Arms Assigned Interventions
Experimental: couples of first-degree family members Drug: Methylphenidate- Ritalin IR (Immediate Release)

Duration of treatment- 4 weeks. Dosage- up to 3 times/day.

  • Ages 6-12, up to 25Kg - 35mg maximum per day.
  • Ages 6-12, above 25Kg - 50mg maximum per day.
  • Ages 12-65, above 25Kg - 80mg maximum per day.

Detailed Description:

Attention Deficit/Hyperactivity Disorder (ADHD) is very prevalent and tends to continue from childhood to adult life. It's heritability is 76%. It was found that there is a greater ADHD prevalence in first-degree families of ADHD subjects- 4-6 times more than the general population.

Pharmacological treatment is the first line treatment today in ADHD, in children and adults, and Methylphenidate (specially Ritalin IR) is the first medication given for the disorder.

The study includes couples of first-degree family members, both diagnosed with ADHD. Subjects will receive Ritalin IR for 4 weeks and undergo several psychiatric and cognitive questionnaires at each time of the follow-up meeting (a total of 3).
