Does genetic disease affect IQ?

Not many smart people like Einstein, but there are localities where people have higher IQs than others.People can't help asking why?

Infectious diseases are a factor in ' taking away ' a large amount of energy used to develop the brain. There is a theory that is the cause of the difference between human intelligence.

According to Livescience , a study showed that a newly born child needs up to 90% of his calories to create and operate the brain. (Even when grown up, that little brain still consumes about a quarter of our energy . ) If in the childhood, when the brain is forming something happens, the brain suffers. Infectious diseases are a factor in ' taking away ' a large amount of energy used to develop the brain . There is a theory that is the cause of the difference between human intelligence.

Many studies show that different IQs between this and other ethnic groups as well as in the same ethnic group differ between one locality and another. Scientists have spent many years exploring the cause. The focus of discussions is what factors, genetics or habitats or both affect the brain.

It is thought that high or low IQ is related to a variety of reasons: whether to study at a young age at a good school, education level, health status, working position, salary, risk of obesity . All both things to consider.

Is there a difference in the intelligence of people in different regions?

Many scientists have mentioned the picture of IQ globally. Nigel Barber said that IQ depends mainly on education. Donald Temper and Haroko Arikawa argue that the cooler the climate, the harder it is to live, to try to survive makes IQ rise. Satoshi Kanazawa assumed the evolution forced IQ to be high in areas far from the evolutionary origin of humans: sub-Saharan Africa. Another hypothesis: Our ancestors who stay in one place do not need to think much, but if they migrate to find new places, meet challenging environments, then intelligence must evolve to survival . This seems to be more reasonable.

In 2010, it was discovered that strong dependence between IQ and infectious diseases by statistical comparisons between these two factors in different regions in different eras and reached the conclusion: Infectious diseases May be the only important basis for predicting average IQ .

The hypothesis seems not only true in countries and geographic regions but also for individuals. There are studies that show that children with intestinal helminthes infection when adults have low IQ. Another study found in many parts of Mexico, the average IQ increased after eradicating malaria. Studies in other countries also confirm this.

In the US, average IQ varies from state to state (people in Massachusetts, New Hampshire and Vermont have high IQ, while in California, Louisiana and Mississippi have low IQ). Infectious diseases are an important basis for predicting IQ and true to survey data. The five states with the lowest IQ are all five with the highest rate of infectious diseases.

So far, the evidence has led to the conclusion that infectious disease is the first cause of change in human intelligence globally. Since this is a ' dynamic ' factor (which can be changed) rather than a genetic factor, it is good news for those who intend to eliminate ethnic inequality, related to the index. IQ (because if only genetic factors are taken into account, it is difficult to change IQ).

The other problem is to find out which infectious diseases have the most impact on brain development.
