Memory and mental functions: which aspects are declining at what age?

Some aspects of cognitive performance (mental) reach their peak at age 22 and begin to decline about 27 years, according to a study published in 2009 in the journal Neurobiology of Aging.

Timothy Salthouse of the University of Virginia and his colleagues conducted the study with 2,000 people aged 18 to 60 years for 7 years. The cognitive abilities were assessed using various tests: solving problems, memorizing words and details of stories, pattern recognition of letters and symbols.

Some aspects of cognitive abilities, such as the speed of thought, reasoning (ability to solve problems), and spatial visualization, were at their peak at age 22 and began to decline about 27 years. The memory remained stable (according to the tests used) until about 37 years and other capabilities that are based on the accumulated knowledge continued to improve up to 60 years.
