Researchers at the National Institute of Genomic Medicine (INMEGEN) announced that they have discovered 636 genes that may be associated to suicide. Additionally, in the study, the Mexican researchers observed that excessive alcohol consumption rises to 10 times the risk of committing suicide, and drug consumption increases the risk of suicide 14 times.
Humberto Nicolini Sanchez, Deputy Director of Basic Research at INMEGEN, said they obtained samples for the study from the Brain Bank of the Forensic Institute in Mexico City. The INMEGEN researcher noted that this is the first time that this type of research is carried out in Mexico in which genomics and hereditary aspects of suicide were analyzed in samples of 44 people who died for this reason and 30 who died from other causes.
Nicolini Sanchez, who is in charge of this research, reported that a group of experts analyzed the frontal cortex of the brain (the area responsible for decision making); and they found alterations in this area in people who died by suicide motives.
“We still have a long way to find more advances in this scientific development, which aims to find genes that predispose a person to commit suicide. This could be used for targeted preventive campaigns,” said the specialist.
Nicolini Sanchez stressed that the age groups at greater risk of committing suicide are those between 15 to 24 years of age and older than 60 years. In addition, of five individuals who attempt suicide, one consumes it.
