Psychiatry looks towards the future in neurodegenerative and neurodevelopmental disorders.

DOI:10.1097/YCO.0b013e32835fd70e The increasing popularity of Current Opinion in Psychiatry is to a large degree because of the journal’s continuing efforts to reinvent itself, not only to stay abreast of the times but also to lead new trends. This issue, with its focus on neurodegenerative and neurodevelopmental disorders, is emblematic of this endeavour. By replacing the Neuropsychiatry focus of the previous years, it is recognizing the fact that a major proportion of Neuropsychiatry has come to deal with neurodegenerative and neurodevelopmental disorders, and that these disorders belong securely in the field of Psychiatry. The decision is also influenced by the structure of classification of mental disorders in the forthcoming DSM-5, with separate chapters for neurocognitive and neurodevelopmental disorders. Of course not all neurocognitive disorders are neurodegenerative, but the latter do comprise the majority, and it is a field in which Psychiatry must retain a firm foothold. This issue highlights three areas in neurocognitive disorders to exemplify the breadth of Psychiatry’s reach. Lövdén et al. [1] (pp. 239–243) critically assess the recent literature on lifestyle change as a strategy to prevent cognitive decline and dementia. This is a topic that has gripped the consciousness of most societies around the world. The promised drug to prevent dementia has not yet materialized, and the aging baby boomers do not have the luxury of time to wait for that breakthrough. The authors conclude in favour of physical exercise, and this is a message that seems ripe for wide publicity. Exercise has so many benefits for both the body and the mind that it should be actively encouraged at both the individual and the population levels. The challenge facing society is how to translate this knowledge into real change, such that the forces of modernity that promote a sedentary lifestyle can be vanquished. Producing behavioral change at a population level is an area for active future research. Surprisingly, the authors reserve their judgement on the benefits of cognitive training, recommending further research. Nutritional supplementation, the third prong of the preventive strategy, appears to
