Abstract

During the last century, many studies have provided evidence that motor dysfunction is an important feature of neuropsychiatric disorders. Despite this, it is a relatively neglected area in mental illness research today. The extensive review of motor abnormalities in psychiatric illnesses by Peralta and Cuesta1 in this issue provides some clues as to why this may be the case. These include the fact that there are many different tools which are used to detect motor signs, and not all of them assess the same signs (supplementary tables S2 and S3). In addition, particular motor syndromes, such as catatonia, may be under-recognized in mental illnesses other than schizophrenia (eg, mood disorders, autism spectrum disorders). The review carefully examines the evidence for motor abnormalities in schizophrenia, mood disorders, obsessive compulsive disorders, autism spectrum disorders, and Alzheimer’s disease. The authors provide compelling evidence that motor abnormalities are not epiphenomena of mental illnesses; they appear to be intrinsically linked to those disease processes that give rise to the cognitive, emotion regulation, and social deficits which are trademarks of these mental disorders. In addition, motor abnormalities seem to be related to similar phenomena across different disorders. They are closely associated with cognitive impairments, appear to track disease burden, and may predict disease progression. In addition, as Schiffman’s2 commentary indicates, many years of retrospective and prospective empirical research provide compelling evidence that motor abnormalities may be an important predictive neurodevelopmental biomarker for psychosis. Motor abnormalities can help separate out subgroups within the same DSM disorder (cf. the greater severity and worse prognosis of non-schizophrenic/non-affective psychoses when associated with catatonia). None of this should be surprising. Given the parallel, modular organization of frontal-subcortical systems, the physiologic (including neurotransmitter) and computational differences contributing to dysfunction within higher-order circuits may also be present within the motor system. As noted in the commentary by Mittal et al,3 cognitive and motor functions are controlled by both the basal ganglia and cerebellar-subcortical circuits, and these 2 circuits work in concert with each other. In addition, cortical regions implicated in cognitive, social, and affective functions exert top-down modulatory effects on cortical and subcortical regions implicated in motor function. Thus the study of motor behaviors and their change over time, or in response to treatment, may eventually provide sensitive indicators of changes in cognitive and emotional regulation systems. There are clear advantages to examining the motor system in psychiatric disorders as a window into cognitive and emotion regulation processes. Motor processes are overtly observable and highly reproducible between laboratory sessions and across multiple settings. They can be readily probed using a range of techniques, including detailed computational analysis of limb and eye movements, direct response to brain stimulation (TMS, tDCS, and related methods), and neuroimaging. Overall, the review and commentaries make clear that the time is now ripe to study motor processes in mental illness and the authors suggest that, given the ubiquitous nature of motor abnormalities in mental illnesses, an approach based upon the NIMH Research Domain Criteria (RDoC) framework may be the best way to start. Similarly, an RDoC perspective to studying the link between motor processes and manifestations of cognitive/emotion regulation processes was the subject of an editorial in Brain.4 Such an approach would provide key insights into the relationship between motor and cognitive dysfunctions, and in particular, the associations between dysfunction in a specific motor circuit and behavioral abnormalities. The need for an RDoC approach to the study of motor systems was put forward by experts taking part in the 2011 RDoC Cognitive Processes workshop. The NIMH RDoC workgroup requested further input from these individuals as well as others with expertise in motor systems. Their input made it clear that including an RDoC approach to the study of motor systems would bring critical insights into psychopathology. Recently, a workgroup of the National Advisory Mental Health Council (NAMHC) was formed to oversee changes to the RDoC matrix. The charge to this workgroup is to oversee all changes in the RDoC matrix going forward. Changes can be proposed by scientists in the field, as well as by members of either the NAMHC workgroup or the NIMH RDoC workgroup. Additions, deletions, or edits regarding particular RDoC constructs will be evaluated via email and/or videoconferencing by a group of ad hoc scientists who are nominated by NIMH program staff, the Council workgroup members, and other scientists.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
