But contrary to what some may think, depression can be predicted, according to a new study published in the American Journal of Psychiatry . The result indicates that long before the first signs, it is already possible to assess the patient’s predisposition.
According to the scientists, genetic alterations present in the DNA may offer an indication of the risks for the disease.
In addition, other risk factors are taken into account, such as some type of childhood trauma, such as sexual abuse, there is a greater chance of developing a depressive condition.
How was it seen in the study?
The researchers used a method to observe the genetic risk of depression in the participants, but it is not so new, as it had already been used to genetically measure the risks of other diseases, such as heart disease and diabetes .
The researchers’ first step was to collect as much genetic material associated with depression from more than 460,000 adults already diagnosed with the disease, in order to have a kind of genetic pattern.
Then, they followed other participants, searching the DNA of these people without a diagnosis of depression for variations related to the disease.
