repair, and the model holds true on every level, from the sub-microscopic realm of DNA to the
               cell, organs, and the entire organism.
               With this understanding, DHEA plays a critical role because it is the most comprehensive
               anabolic (repair) signal in the human body. It can therefore help to tip the see-saw in your favor
               by supporting repair functions throughout the body and brain. Moreover, DHEA has been shown
               to reduce cellular damage via its antioxidant and immune-stimulating activity.

               Another long-term factor contributing to “the DHEA advantage” arises from a reduction in stress
               hormone-related catabolic damage. Elevated stress hormones and low DHEA are strongly
               associated with immune suppression, depression, brain degeneration, and even
               dementia.31,32 Conversely, DHEA supplementation has been shown to effectively reduce this
               type of degeneration.33

               Naysayer: Still, the only intervention that has been proven to slow or reverse the aging process
               is calorie restriction.

               Stephen Cherniske: You’re right that calorie restriction can prevent disease, maintain health and
               youth in animals at advanced ages, and even extend maximal life span to the human equivalent
               of 140 years.
               But one of the most remarkable observations seen in calorie-restricted animals, including
               primates, is that the treatment raises DHEA levels.34 In fact, some leading endocrinologists
               believe that the improvements in health and longevity from calorie restriction stem in great part
               from the life-long maintenance of DHEA.35-37 Again, these are long-term influences on
               immunity, glucose tolerance, body composition, and cardiovascular risk factors that would be
               missed in short-term studies.

                                       DHEA AND WELL BEING: STUDY ABSTRACT
               “This study evaluated the efficacy of the adrenal androgen, dehydroepiandrosterone, in the
               treatment of midlife-onset dysthymia. A double-blind, randomized crossover treatment study
               was performed as follows: 3 weeks on 90 mg dehydroepiandrosterone, 3 weeks on 450 mg
               dehydroepiandrosterone, and 6 weeks on placebo. Outcome measures consisted of the
               following. Cross-sectional self-ratings included the Beck Depression Inventory and visual
               analogue symptom scales. Cross-sectional objective ratings included the Hamilton Depression
               Rating Scale, the Cornell Dysthymia Scale and a cognitive test battery. Seventeen men and
               women aged 45 to 63 years with midlife-onset dysthymia participated in this study. Response to
               dehydroepiandrosterone or placebo was defined as a 50% reduction from baseline in either the
               Hamilton Depression Rating Scale or the Beck Depression Inventory.

               RESULTS: In 15 patients who completed the study, a robust effect of dehydroepiandrosterone
               on mood was observed compared with placebo. Sixty percent of the patients responded to
               dehydroepiandrosterone at the end of the 6-week treatment period compared with 20% on
               placebo. A significant response was seen after 3 weeks of treatment on 90 mg per day. The
               symptoms that improved most significantly were anhedonia, loss of energy, lack of motivation,
               emotional “numbness,” sadness, inability to cope, and worry.
               CONCLUSIONS: This pilot study suggests that dehydroepiandrosterone is an effective
               treatment for midlife-onset dysthymia.”21

               Naysayer: That’s just it. There doesn’t seem to be any long-term studies to back up the anti-
               aging claims for DHEA.
