The more time a child spends watching television, the more profound the changes.
Watching too much TV can change a child's brain structure in a detrimental way, according to a new study. The Japanese study examined 276 children between the ages of five and 18, who watched zero to four hours of television per day, averaging about two hours.

Watching too much television can change the structure of a child's brain in such a way that it can lead to lower verbal ability.
The MRI images showed that children who spent more hours in front of television had greater amounts of gray matter in the front of the frontal lobe. However, This increase in gray matter in this area of the brain is detrimental as it is linked to a lower verbal ability, according to the authors of Tohoku University in Sendai City.
"In conclusion, watching television is directly or indirectly related to the neurocognitive development of children »the researchers wrote.
The authors said that the impact of television on the "structural development" of the brain has never been investigated.
However, the results, published in the journal Cerebral cortex, highlighted an association between watching television and changes in the brain, but they do not prove that television caused these changes.
Perhaps this loss of verbal ability is because children who spend too much time watching television read less and interact less with family and friends.
Scientists also cannot claim that this is the cause. Source
I leave you with this mythical TVE commercial that encourages children to watch television less. It's from when there were only two channels 😉
