Is Obesity Linked to ADHD?

Is Obesity Linked to ADHD?

With the increasing number of children eating a high-fat diet, more and more overweight, the incidence of type 2 diabetes and hypertension and other diseases has been steadily growing among the population. 

However, these may not be the only health problems associated with children between this surge in overeating. In a recent study from the University of Illinois researchers found that high-fat diet may also be associated with impulsive, depression, anxiety disorders and attention deficit hyperactivity disorder.

4-week-old mice to see if the animals for one to three weeks of high-fat diet will affect the behavior of living. The mice were randomly divided into two groups, the first group ate, of which 60% of calories from fat diet, and the second group ate a diet, only 10% of calories from fat. Eat a high-fat diet, a week later, the first group of mice showed increased levels of anxiety, the more time that caveman and wheel running. Further, in the first group of mice hesitate to zero maze Explore open quadrant. They also can not navigate Y-maze, and acknowledge that a new object.

When the researchers analyzed the cortex, hippocampus and hypothalamus dopamine in a group of mice, they found that the hippocampus and cortex homovanillic acid (HVA) raise the level of. HVA produce a byproduct of the metabolism of dopamine. This means that, in the group of low levels of dopamine in mice. Dopamine is important because it is a neurotransmitter, transmit impulses from one nerve cell to another nerve, organ or tissue. Dopamine levels low negative impact on the ability to think, concentrate. It will also affect motor coordination. Individuals with low levels of dopamine in Parkinson's disease.

The level of dopamine in another part of the brain called the dorsal striatum control the individual's ability to enjoy the rewards like to eat. Dysfunctional dorsal striatum dopamine signal to the brain enough food has been consumed will lead to excess consumption, leading to obesity.

HVA in the presence of high levels of animal hippocampus and cortex and reduced in the cortex of brain-derived neurotrophic factor gene, which means that it produces protein levels were also reduced. The growth of new neurons in this protein can help the survival of existing neurons and AIDS. Without these neurons, learning and memory may be affected.

The researchers also found that the damage reversal of learning and memory to a group of mice Ritalin caused by eating a high-fat diet. To their antidepressants Vestra Norpramin has no effect on memory and learning impairment
