When the tests repeated four years later, found that IQ has increased in some cases and in others decreased up to 20 points , and the changes coincided with changes in brain structure. Specifically, changes in verbal IQ were associated with changes in a brain area related to speech, the left motor cortex, while increases in non-verbal test scores is associated with increased gray matter density earlier in the cerebellum, which integrates sensory and motor information and participates in the movements. "We tend to advise children and decide the future course of their education when they are young, but just check that your intellect is still evolving and may even improve until much later, "say the authors of the research. They add that the study confirms that brain structure can change in adulthood, and IQ as well, because our brain is constantly adapting.

IQ can vary over the life
The intelligence quotient (IQ) , the standard that measures a person's intelligence, you can increase or decrease during adolescence, according to a study by University College London (UK) published in the journal Nature . This is the first study to suggest that this value is not constant throughout life . In a series of experiments conducted in 2004 adolescents aged between 12 and 16 years, researchers led by Cathy Price, analyzed using of magnetic resonance brain structures of the subjects as well as subjecting them to tests of intelligence .
When the tests repeated four years later, found that IQ has increased in some cases and in others decreased up to 20 points , and the changes coincided with changes in brain structure. Specifically, changes in verbal IQ were associated with changes in a brain area related to speech, the left motor cortex, while increases in non-verbal test scores is associated with increased gray matter density earlier in the cerebellum, which integrates sensory and motor information and participates in the movements.
