In early September, The American Journal of Psychiatry accepted the paper "Depression-related increases and decreases in appetite reveal dissociable patterns of aberrant activity in reward and interoceptive neurocircuitry" by Dr. Simmons and his colleagues.
This paper provides important evidence about why some individuals lose their appetite when they get depressed, while others feel driven to eat more. Using sophisticated behavioral tasks and functional Magnetic Resonance Imaging (fMRI), Dr. Simmons and his colleagues have demonstrated that activity in the brain regions important for reward and monitoring the body's homeostatic needs distinguishes between depressed individuals who eat too much and those who eat too little.
