Utilización de resonancia magnética funcional 3T para evaluar los efectos del metilfenidato sobre la función de atención en pacientes con déficit atencional

our objective was to assess the level of attention in patients with attention-deficit disorder using functional mri by comparing test results before and after the use of methylphenidate. we studied 6 pediatric patients and 2 adults. all of them were subject to a attention test before and after methylphenidate administration. the pediatric patient population showed a positive difference, with higher levels of attention in the methylphenidate group. in the adult group, improvement in the attentional function was observed in one of them. this method allowed us to physiologically assess if improvement in attentional function occurred after methylphenidate administration. therefore, this technique is viewed as an important tool for evaluating the usefulness of treatment for attention-deficit.hyperactivity disorder.
