Question

A brain imaging study showed that, in healthy children, peak cortical thickness occurred around the age of 7.5 years, and in children with ADHD, on average around 10.5 years. This finding implies that children with ADHD ____.
a.​ will never catch up with their same-age peers.b. ​can be expected to lag behind their same-age peers in some tasks but will eventually experience improvement.c. can be expected to go through puberty approximately 3 years behind their same-age peers.d. will never be as intelligent as their same-age peers.

Answer 1

Answer:

The correct answer would be option B.

Explanation:

In neural antomy, cortical thickness is the morphomateric calculation or measurement of the brain that provide the information about the overall thickness of the various layers of the cerebral cortex.

The normal range of the peak cortical thickness is around 7.5 to 8 which means that the same age group kids brain is develop at this age where is in ADHD child it is found according to the question is 10.5 years, which means he is taking 3 years extra to develop the cortex of the brain which means he would be slow in comparison to the similarly age group kids but will improve with the time.

Thus, the correct answer would - option B.
