Too much manganese sparks attention deficit problems

Attention deficit hyperactivity disorder (ADHD) is one of the most common disorders among children. The symptoms include hyperactivity, impulsiveness, and basically being inattentive while play, at school or at home. While everyone has the tendency of being hyperactive or being inattentive, for children with ADHD, this gets in the way of living a normal life.

According to a study published by the Environmental Health Perspectives, there seems to be a link between high manganese diet and a negative attention span found in animals. The research carried was conducted by Donald Smith. In the study mentioned earlier, rats were exposed to a high manganese diet. The rats were then trained from a young age to look at a wall. They attempted to distract the rats by introducing a scent in the chamber.

They studied the behaviour of the rats for months and found that rats with manganese paid selective attention to the process compared to the rats that were not given a high manganese diet. The tendency for selective attention changed as the rats matured in age.

In fact, Smith says that even though some rats were given small doses for a long duration, the most attention deficit problems were seen in newborn rats that were exposed to a high manganese diet. So, Smith declares that if the dosage levels are known for adults while the babies are in the womb of during the early days, a stronger link to ADHD can then be associated.

He maintains that although there may be other factors that affect ADHD in humans, they did successfully discover that high manganese exposure can be one of those external factors that spark ADHD in children.
