Forensic testing of blood can now determine if anti- depressants were the cause of violent behaviour, including murder or suicide, new research has found.
Genetic variations in metabolism affect how different people react to anti-depressants, and now medical examiners say they can identify those variations, and use the evidence to “potentially absolve people charged with homicide”, and explain why they acted like they did.
The research, published recently in the Journal of Forensic and Legal Medicine, was carried out by a medical specialist, a forensic psychiatrist and a pharmacogeneticist. It looks specifically at three cases where people with no previous diagnosis, who were prescribed antidepressants for stress-related issues, ended up killing others, with two attempting suicide.
“An out-of-character unmotivated homicide or suicide by a person taking medication might be chemically induced and involuntary. The capacity to use frontal lobe functions and control behaviour can be impaired by brain toxicity,” the paper states.
