Zinc sulfate helps attention-deficit disorder?
Attention-deficit disorder itself is a common disorder which affects 4-12% of elementary school children. Symptoms of ADHD include features of inattention, hyperactivity, and impulsivity. For children with ADHD, the disorder can interfere with social relationships and have a profoundly negative impact on their school performance.
Croatian researchers published a recent study discussing the role of zinc in the pathophysiology of attention deficit disorder. As they noted, the neurotransmitter, dopamine, is one of the most important factors in this disorder. Further, they noted that the hormone, melatonin, also plays a role in the regulation of dopamine.
To continue further, these researchers also discussed the role of the mineral, zinc, in the metabolism of melatonin. Zinc sulfate has favorable effects in children with ADHD which suggests that zinc deficiency may play a role in the pathophysiology of ADHD. In fact, preliminary investigations suggest that children with ADHD may have lower zinc concentrations than those that do not.
In a recent study, a dose of 55 mg/day of zinc sulfate improve symptoms of ADHD in children. The study authors suggested that further studies are necessary to elucidate a more precise dosing regime for zinc sulfate in children with ADHD.
