2010 has been an interesting year for DHEA research related to mental health issues. The role of DHEA in Alzheimer’s [1, 2], neurogenesis , depression , problem solving  PTSD / childhood abuse , drug seeking behavior , and neurocognitive deficits in schizophrenia  show that DHEA may become an alternative or adjunct to psychoactive medication for both medical and non-medical practitioners to consider. Of course this raises the question of safety, and this year’s crop of research has also been interesting in that arena, suggesting that DHEA is a safe option for most people.  My read is that DHEA supplementation can be safely considered on a case by case basis for a wide range of mental health concerns.
