Aptitude
An aptitude is an innate inborn ability to do a certain kind of work. Aptitudes may be physical or mental. Aptitude and intelligence quotient are related, and in some ways opposite, views of human mental ability. Whereas intelligence quotient sees intelligence as being a single measurable characteristic affecting all mental ability, aptitude breaks mental ability down into many different characteristics which are supposed to be more or less independent of each other. However, a casual analysis of any group of test scores will nearly always show them to be highly correlated.

Oct. 3, 2026 Scientists have linked a gut bacterial compound called ImP to greater Alzheimer’s risk, harmful brain protein buildup, and faster cognitive decline. The finding raises the possibility that reducing ImP in the blood could one day help slow or ...
Oct. 1, 2026 People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss over time, with the strongest differences equivalent to about 2.5 years of delayed brain aging. Berries and poultry were linked with healthier ...
Oct. 1, 2026 People with depression who dramatically cut ultra-processed foods experienced notable improvements in their symptoms in a small preliminary study. Researchers suspect healthier eating may benefit the brain partly by reducing gut damage and chronic ...
Oct. 1, 2026 The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing promising new targets for ...
Sep. 30, 2026 A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the ...

Sep. 29, 2026 Depression may change which emotional faces children notice most, but the pattern appears to depend on family history. Children at higher familial risk became increasingly focused on sad faces, while lower-risk children with rising symptoms paid ...
Sep. 29, 2026 A massive MRI study found that Alzheimer’s disease, mild cognitive impairment, psychiatric disorders, and addiction are associated with distinct patterns of accelerated brain aging. The strongest effects appeared in Alzheimer’s and mild ...
Sep. 28, 2026 A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impulsivity, while also producing measurable changes in ...
Sep. 28, 2026 Strengthening the body’s natural daily rhythms helped mice recover after stroke by improving the brain’s waste-clearing system and reducing lingering inflammation. The approach worked even when treatment began three days after the stroke, ...
Sep. 27, 2026 Scientists found that immune cells contributing to Alzheimer’s-related brain damage may be activated in lymph nodes outside the brain before traveling into the nervous system. Blocking this pathway in mice dramatically reduced neurodegeneration ...
Sep. 27, 2026 A large health-record analysis found that glucosamine use was associated with a 25% higher likelihood of mild cognitive impairment progressing to dementia. Lab experiments suggest the popular joint ...
