The study brought together data from 12 different countries. Some 30,000 people, aged more than 45 years, took cognitive function tests that included tests of simple, repeated coding under pressure of time.
Researchers then processed the results alongside details of each person's genome to identify genetic variants or changes associated with speed of thinking skills.
According to the press release, they found that people with slower brain processing speed overall were found to have variants near a gene, called “CADM2.”
The study confirmed the likely role of CADM2 in between-cell communication, and therefore cognitive performance, said lead researcher Carla Ibrahim-Verbaas.
The study, published in the journal Molecular Psychiatry, involved researchers in Australia, Austria, Croatia, Finland, France, Germany, Holland, Iceland, Ireland, Italy, the United Kingdom and the United States.
