Other monoaminergic, peptidergic, and neuroenocrine systems have been implicated as well. A review of studies that examine neurobiological variables in postmortem tissue of suicide victims and controls reveals reveals that investigators in most instances have viewed age as a confound to be controlled rather than considering it as a variable of interest. However, the close associations between aging andincreased suicide rates, and the knowledge that the functional integrity of many of these same systems changes with normal and abnormal aging processes, raise the possibility that biological aging contributes to suicide risk, and that the underlying neurobiology of suicide in the elderly differs from taht of younger people. The few avialable studies that did examine the associations of age with neurobiological measures indiocate directions for future research into the role that aging may play in determining the biological bases of suicide risk.
