Botulinum toxin injections improve depression

At the American Academy of Dermatology (AAD) 72nd Annual Meeting, presented March 22, 2014, clinical associate professor of psychiatry at the University of Texas Southwestern in Austin and Allergan consultant (makers of Botox), Michelle Magid, MD presented research suggesting botox (botulinum toxin) injections improved symptoms of depression, even after the forehead wrinkles returned.  The researchers were encouraged by this particular finding, suggesting that the anti-depressant effect isn’t just related to the cosmetic improvement of erasing wrinkles.  Skeptics point out that although the study is interesting, the results are complicated because the subjects were able to see the cosmetic improvement from the botox injections.

Dr. Magid explained to Medscape Medical News that two possible reasons exist for the improvement in depressive symptoms.  “The first is that the botulinum injections made it difficult for the subjects to frown. If individuals smile more and frown less, they are likely to have better social experiences, which could lift mood. The second possibility, favored by Dr. Magid, is a biologic explanation. MRI studies have shown that when people are unable to make angry facial expressions because of botulinum injections to the glabellar region, there is less activity in the amygdala than expected. Such a connection could be mediated by the trigeminal nerve, which links the glabellar region to the brain stem and amygdala and is the control center of anxiety, trauma, and the heightened fear response. If a person can’t frown, the brain does not register a frown, and the amygdala does not get the trigger that the person is upset”.  It is interesting to note that patients with depression and anxiety were affected more significantly than those with strictly melancholic depression.  Read the entire article written by Jim Kling for Medscape Medical News here.

 

The hormone cure: Adrenal fatigue

Another informative and honest video from Sara Gottfried, MD about what’s going on with our stress hormones and how to talk to your general practitioner about getting your hormones tested.  I know so many people in Austin who have had major hormones issues and hit their heads against the proverbial brick wall while talking with their docs about getting tested and what is considered “normal”.  Some people I know have even gone out of town (to Dallas) to find someone, anyone, who can help.  Thank you Dr. Sara for this educational Normal vs. Optimal Lab Ranges Related to Adrenals pdf!

My mom was right when she said everything changes after 40 and finally someone (a medical doctor) has researched how to avoid the pitfalls of female hormonal changes and fix the ones you’ve got.  This is a must for every woman!  You can take her hormone quiz here and get her hormone toolkit pdf here.

 

Grain Brain: Gluten linked to dementia

From Medscape Neurology, January 21, 2014 issue, Bret S. Stetka, MD and David Perlmutter, MD discuss Dr. Perlmutter’s best selling book.  “Medscape spoke with Dr. Perlmutter about his thoughts on the impact of carbohydrates and gluten on the brain.  In his new book Grain Brain: The Surprising Truth About Wheat, Carbs, and Sugar — Your Brain’s Silent Killers, Dr. David Perlmutter, Associate Professor at the University of Miami School of Medicine, advocates that lifestyle modifications, starting with a high-fat, nearly carbohydrate-free diet, can prevent or greatly lower dementia risk and progression — and he’s armed with plenty of data to back up the claim. But detractors say the evidence isn’t quite there.”  Read the interview here.
