Although one of the most common mental disorders, depression can be an obscure illness. People keep their depression secret, doctors and patients have a hard time recognizing it, the cause is unknown, treatment is viewed with suspicion, and other conditions are given higher priority. However, once you know the right questions to ask and the correct manner in which to ask them, diagnosis and treatment is easy. An Atlasof Depression presents a thorough graphical review of the diagnosis, management, and treatment of affective or “mood” disorders. Authors Baldwin and Birtwistle explore the overlap of anxiety and the depressive syndromes in community, primary, and secondary care settings. They cover the symptoms of depressive disorders such as low mood, reduced energy, a loss of interest or enjoyment, poor concentration, reduced self-confidence, guilty thoughts, pessimism, thoughts of suicide, disturbed sleep, and altered appetite.
