A gene variant associated with serotonin transport (STG) , and normally associated with depression is strangely more prevalent, but also less likely to induce depression in collectivistic East Asian cultures. The study took data from 29 countries, and found a consistent trend towards this same genetic variant being strongly associated with episodes of major depression in Western cultures.

Ecstasy's long-term effects revealed. "Enough time has finally elapsed to start asking if ecstasy damages health in the long term. According to the biggest review ever undertaken, it causes slight memory difficulties and mild depression, but these rarely translate into problems in the real world. While smaller studies show that some individuals have bigger problems, including weakened immunity and larger memory deficits, so far, for most people, ecstasy seems to be nowhere near as harmful over time as you may have been led to believe."

Serotonin and Depression: A Disconnect between the Advertisements and the Scientific Literature

The machine that makes you a savant. (NY Times, No registration copy here) Transcranial Magnetic Stimulation sounds sketchy at first, but there is growing evidence this device developed for brain mapping can change and maybe even enhance mental functions, and may (or may not) be especially useful against depression. The results of the first major US trials will come out in 2006, as discussed in this MIT Tech Review article (PDF). Are you ready for one at home?

A review of the current state of gender based brain research shows that women and men differ both in the way their brains are constructed and in how they function.

..correlation between brain region size in adults and sex steroid action in utero suggests that at least some sex differences in cognitive function do not result from cultural influences or the hormonal changes associated with puberty--they are there from birth.

Treatment for such things as schizophrenia and depression will likely have gender specific variations in the future. Previously, brain research that examined gender differences was considered controversial because it was argued that the results might give rise to more sex discrimination against women. That view may be changing.
