It has become our mantra at NIMH that mental disorders can be addressed as disorders of brain circuits. We frequently use an analogy with heart disease: mental disorders can be thought of as conduction problems or arrhythmias, in contrast to neurodegenerative disorders (Parkinsons, Huntingtons, Alzheimers), which involve loss of tissue similar to the infarctions of ischemic heart disease.
