Description of intervention(s) / exposure
Treatment: Drugs - Methylphenidate Hydrochloride
Treatment: Drugs - Placebo

Experimental: Sequence A: Methylphenidate, Placebo - Participants will first receive methylphenidate capsules twice daily for four weeks. Doses will be administered four hours apart. The maximum dose is determined based on the participant's weight. After a 2-day washout, participants then receive Placebo (matching methylphenidate capsules) twice daily for four weeks.

Experimental: Sequence B: Placebo, Methylphenidate - Participants will first receive Placebo capsules twice daily for four weeks. Doses will be administered four hours apart. After a 2-day washout, participants then receive methylphenidate capsules (matching Placebo capsules) twice daily for four weeks. The maximum dose is determined based on the participant's weight.


Treatment: Drugs: Methylphenidate Hydrochloride
Participants will receive twice daily doses of Methylphenidate Hydrochloride four hours apart. There will be three dosage schedules, determined based on three weight ranges (20-30kg; 30-40kg; =40kg). For children weighing 20-30kg, the maximum daily dose will be 20mg. For children weighing 30-40kg, the maximum daily dose will be 30mg. For children weighing =40kg, the maximum daily dose will be 40mg.

Treatment: Drugs: Placebo
Participants will receive twice daily doses of placebo capsules. Gelatine placebo capsules will contain hypromellose, an inert substance.
