newsletters. Those updates are compiled in this volume. Dr. Daniel Carlat wanted to make sure readers understand something about how research studies are designed and how you can decide whether to trust the results or not. He wrote a “Quick primer on Study Design and Statistics.”  Finally, he also wrote 50 multiple choice questions so clinicians can assess their understanding of these study results and earn CME credits.  Does light therapy work for non-seasonal depression? Should you heed the FDA recommendation to use no more than 40 mg of citalopram for your patients?  Is regular cannabis use really bad for teenagers?  Does antidepressant use in pregnancy increase the risk of autism?  What’s a promising new treatment for clozapine induced drooling? Does heavy drinking really imply a drinking problem? Do e-cigarettes help smokers quit? Does Straterra increase suicide risk? Can pets be good for your patient’s mental health?  And the list goes on.
