Research trends in the neuropsychiatry literature since the new millennium

The authors examined current research trends in neuropsychiatry by analyzing original research studies published since the new millennium. A total of 14,587 articles published between 2000 and 2013 were systematically screened from 10 neuropsychiatry journals, which were selected based on impact factor ranking. Clinical studies accounted for the highest proportion of neuropsychiatry research articles published since the new millennium (N=5,097; 68.9%), followed by laboratory studies (N=1,824; 24.7%) and service evaluation, classification, and historical studies (N=474; 6.4%). This study confirms that neuropsychiatry is a quintessentially clinical discipline with a continuing focus on phenomenological aspects, possibly reflecting the centrality of clinical observations to the diagnostic process.
