Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.
<h3>How brain changes in late adulthood?</h3>
The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.
The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine.

In order to validate his tool, and know if it will give acceptable results, he compares his tool with others than have already been established, and scientifically proven as effective. As such, he not only will ask participants in his study respond to his instrument, but he will also apply one that has already been used with that purpose: the Beck Depression Inventory, and another one that will measure factors not related to depression, known as a social desirability scale. With the results from all three tools, Dr. Gonzalez will be able to ascertain the validity of his own scale, and test it against others. In this way, he is further vaidating his results as well, and showing the accuracy of his own instrument.
