Although smoke detectors often react As Drs. There’s an increase in rumination, the obsessing over the source of one’s pain. Studies of depression in rats show that the 5HT1A receptor is involved in supplying neurons with the fuel they need to fire, as well as preventing them from breaking down. The desire for social isolation, for instance, helps the depressed person avoid situations that would require thinking about other things. Indeed, when you are faced with a difficult problem, such as a math problem, feeling depressed is often a useful response that may help you analyze and solve it. immune systems operated under a "smoke-detector principle." Evolutionary approaches to depression are attempts by evolutionary psychologists to use the theory of evolution to shed light on the problem of mood disorders. This is not to say that depression is not a problem for those affected. What if mental illness, as Malcolm Gladwell says in his book, … In a study of 61 depressed subjects, 4 out of 5 reported at least one upside to their rumination, including self-insight, problem solving, and the prevention of future mistakes.I suffer from migraines, which are bizarre episodes. Raison recently joined the UA to further his research in mind-body medicine.

"Moreover, significant data suggest that at least some depressive symptoms actually may help people avoid infection or survive it when it occurs." Depression as an evolutionary advantage? These important processes allow depressive rumination to continue uninterrupted with minimal neuronal damage, which may explain why the 5HT1A receptor is so evolutionarily important.Many other symptoms of depression make sense in light of the idea that analysis must be uninterrupted. In order to meet this criteria, the evolutionary hypothesis would have to show that simply being depressed helped depressed individuals to obtain an advantage in reproducing themselves and bringing their own offspring to reproductive maturity. infection responses to acute (or short-term) stressors. children were especially susceptible as 30.4% of all deaths occurred before the age of 5 years.

Evolutionary thinking provides an account of the origin and function of most human characteristics. In an One reason to suspect that depression is an adaptation, not a malfunction, comes from research into a molecule in the brain known as the 5HT1A receptor. We want to hear what you think about this article. (There are several effective therapies that focus on just this.)
