Adverse Effects | Aggressive Behavior Induced by Selective Serotonin Reuptake Inhibitors (SSRIs) During the First Month of Treatment

Adverse Effects research study

What is the primary objective of this study?

SSRIs are the first line of therapy for anxiety and depressive disorders and for many other clinical diagnoses. One of the most disturbing side effects that is observed is a tendency towards aggressiveness among patients receiving medications from this group, mainly during the first month of therapy. Aggressive behavior tends to occur in some individuals but not in others. In some sub-groups of people, personality and character traits might make a person more prone to aggressive behavior. In this study the investigators try to estimate the tendency towards aggressive behavior in patients prescribed to a medication from the SSRI group. By using a comparative computer simulation they hope to be able to detect delicate changes and to maybe get some clues of the personalities prone to aggressive behavior in the future.
