Mental ability can remain stable or even improve with age in certain areas, such as vocabulary, knowledge, and wisdom. Older adults often have a wealth of experience and insights that contribute to better problem-solving and decision-making skills. Additionally, engaging in regular cognitive activities, like puzzles or social interactions, can help maintain or enhance mental agility throughout the aging process. This demonstrates that while some cognitive functions may decline, others can thrive with the right stimulation and lifestyle choices.
IQ = mental age / chronological age x 100
recently the age has declined it is now 9
Alfred Binet and Theodore Simon created the first standardized intelligence test in 1916. Francis Galton made the first attempt to create such a test before them, but was unsuccessful in creating a test because he could find no correlation between physical development and mental development. Binet and Simon created a test that would require participants to give answers that would relate to their "mental age", meaning that the more advanced the question, the more likely an older participant would be able to answer correctly. This mental age reflected the mental ability of a child. If a child had a higher mental age than his/her chronological age, (for example, an 11 year old scores a mental age of 13) then the child was considered gifted or mentally advanced. If a child had a lower mental score than his/her chronological age, (for example, an 11 year old scores a mental age of 10) then the child was seen as underdeveloped or mentally retarded.
Basically it means how old your character is, for example, if a someone who was 20 had a mental age of 6 they would probably be acting like a 6 year old and have similar characteristics. Mental age is a controversial concept in psychometrics. It is an intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. Hope this helps :D
An example of demographic momentum is when a population continues to grow even after fertility rates have declined to replacement levels. This is because there are proportionately more women in the reproductive age group, leading to a continued increase in population size.

Intellectual functioning level is defined by standardized tests that measure the ability to reason in terms of mental age (intelligence quotient or IQ).

You should really discuss this with a professional. We do not know, for example, the accuracy of the "undetected mental breakdown" report, since it was not observed or treated at the time.
To determine your mental age based on a score of 20 out of 30, you can calculate it as a percentage: ( \frac{20}{30} \times 100 ) equals approximately 66.67%. If this percentage corresponds to a specific mental age scale, you would need to reference that scale to find the equivalent mental age. Generally, in some assessments, this score might suggest that your mental age is around two-thirds of the chronological age assessed.
At what age one is mentally, for example, someone who is very mature may have one much larger than their actual age. Whereas someone who is immature or suffers from a mental disorder may have one lower.
