Abstract

Background

Psychomotor alterations are a common symptom in patients with major depressive disorder (MDD). The primary motor cortex (M1) plays a vital role in the mechanism of psychomotor alterations. Post-movement beta rebound (PMBR) in the sensorimotor cortex is abnormal in patients with motor abnormalities. However, the changes in M1 beta rebound in patients with MDD remain unclear. This study aimed to primarily explore the relationship between psychomotor alterations and PMBR in MDD.

Methods

One hundred thirty-two subjects were enrolled in the study, comprising 65 healthy controls (HCs) and 67 MDD patients. All participants performed a simple right-hand visuomotor task during MEG scanning. PMBR was measured in the left M1 at the source reconstruction level with the time–frequency analysis method. Retardation factor scores and neurocognitive test performance, including the Digit Symbol Substitution Test (DSST), the Making Test Part A (TMT-A), and the Verbal Fluency Test (VFT), were used to measure psychomotor functions. Pearson correlation analyses were used to assess relationships between PMBR and psychomotor alterations in MDD.

Results

The MDD group showed worse neurocognitive performance than the HC group in all three neurocognitive tests. The PMBR was diminished in patients with MDD compared to HCs. In a group of MDD patients, the reduced PMBR was negatively correlated with retardation factor scores. Further, there was a positive correlation between the PMBR and DSST scores. PMBR is negatively associated with the TMT-A scores.

Conclusion

Our findings suggested that the attenuated PMBR in M1 could illustrate the psychomotor disturbance in MDD, possibly contributing to clinical psychomotor symptoms and deficits of cognitive functions.

Background

Major depressive disorder (MDD) is not only characterised by abnormalities in mood and affect but also substantial disturbance in cognition and psychomotor function. Psychomotor alterations have been recognised as one of the crucial features of MDD [1]. The term psychomotor is composed of two parts: "psycho" and "motor," with the former referring to cognitive processes and the latter to motor processes [2]. Psychomotor functions are the foundation of the plan and execution of various behaviour, including speech, facial expression, and cognitive function [3]. Some findings showed that one aspect of psychomotor alterations, namely psychomotor retardation (PMR), is related to the severity of depression [4] and poor response to antidepressants [5], ultimately contributing to impaired social function and quality of life [6]. Understanding the neuronal basis of PMR could therefore ultimately contribute to development of treatments permitting improved quality of life.
Despite this importance, research on psychomotor issues in MDD is quite scarce. Previous work has primarily probed the pathophysiology of psychomotor alterations in mood disorders [7]. It has been suggested that the mania state in mood disorders is associated with psychomotor excitation, while the depressive state is mainly related to psychomotor inhibition [8]. A small handful of studies have found that the psychomotor function is modulated by the sensorimotor network [2, 9]. It was suggested that the psychomotor alterations in patients with MDD are correlated with neural circuitry involving the prefrontal cortex, motor-related cortex and basal ganglia [1]. In particular, PMR is due to the alteration of cerebellar-thalamo-cortical motor circuitry [10]. Existing functional imaging studies have demonstrated that psychomotor alterations are related to decreased blood flow in the dorsolateral prefrontal cortex, left prefrontal cortex, angular gyrus, and anterior cingulate [1113]. Furthermore, structural imaging studies revealed that psychomotor speed is associated with alterations of white matter in motor-related pathways [1416]. A study discovered that aberrant cerebral blood flow (CBF) in the centre of the motor-regulating circuit might account for the PMR in MDD using a perfusion MRI approach [17]. Therefore, structural and functional alterations in the motor-related cortex might result in the PMR in MDD. Although the engagement of sensorimotor cortices in psychomotor function is preliminarily documented, the specific brain activity pattern remains ambiguous.
Magnetoencephalography (MEG) allows non-invasive inference of current flow in neuronal cell assemblies through measurement of extracranial magnetic fields. Due to its high temporal resolution, MEG is ideally suited to capturing neural activity during psychomotor processes. A well-characterised neurophysiological feature associated with cognition and motor control is beta-band oscillations [18]. They play a vital role in long-range communication on a cortical network level and in particular, mediate feedback influences through which higher brain centres influence centres lower in the processing hierarchy [19]. Based on previous research, MDD is characterised by dominant beta oscillations [20, 21]. In our initial studies, spontaneous central beta power might be a potential biomarker of MDD [22, 23]. Moreover, we found that resting-state beta-band oscillations are related to response speed [24] and process speed [25]. These investigations have advanced our understanding of the impact of MDD on sensorimotor cortical oscillations. However, due to a lack of task-based evidence, motor-related beta oscillation pattern and the relevance of brain abnormalities in motor systems to psychomotor disturbances in MDD remain largely unknown.
As depicted in Fig. 1, a power reduction in beta bands across sensorimotor regions is present before movement onset and during movement execution, i.e., movement-related beta reduction (MRBD) [19]. Following the end of the movement, post-movement beta rebound (PMBR) occurs, defined as an increase in beta amplitude relative to baseline [26]. This response typically occurs 500 ms after movement termination and lasts for several seconds (Fig. 1A). Previous studies have suggested that the PMBR originates in the sensorimotor network [18], particularly M1 [27]. There is evidence that MRBD and PMBR may originate from different brain regions. Specifically, MRBD is usually located in the postcentral gyrus, while PMBR locates in the precentral gyrus (Fig. 1B) [27, 28]. Moreover, the two stage-dependent alterations may play different roles in sensorimotor processes. As PMBR is well-accepted to be involved in motor inhibition [29] or sensory feedback [30] in motor cortices, it could regulate cortical sensory processing and motor output [31], which further supports the notion that sensorimotor beta modulation may be a key marker to investigate psychomotor process [32]. Moreover, PMBR may contribute to visuomotor adaption by maintaining or updating the forward model that guides movement [33]. Altogether, previous neurophysiological studies have highlighted that the strength of motor-related beta oscillations is directly related to cognitive-motor performance.
Research in healthy individuals demonstrated that the decrease of PMBR leads to a slower movement state [34], consistent with reduced movement-related beta activity in Parkinson's disease (PD) [35]. Many physiological or pathological factors influence beta oscillations, such as healthy ageing [3645]. Previous studies found that poor motor performance in healthy older adults is related to changes in beta oscillations. Importantly, neuropsychiatric studies also revealed that decreased PMBR in PD [4648], SCH [4951], schizotypal personality disorder (SPD) [52], autism spectrum disorder (ASD) [5355], reflecting impaired sensorimotor integration in psychiatric disease. In general, these findings indicated that the aberrant PMBR impacts motor-related activity and advanced sensorimotor integration. Despite some studies reporting this movement-related neurophysiological modulation in clinical and non-clinical populations, the alteration of PMBR and its association with psychomotor disturbance in MDD remains underexplored.
In this study, we specifically addressed PMR in MDD using MEG technique combined with experimental motor tasks, clinical ratings of psychomotor disturbance, and neuropsychological tests involving psychomotor speed. We aimed to investigate the abnormal beta oscillations pattern in MDD and its potential association with psychomotor alterations. Based on available evidence, we hypothesised that patients with MDD have attenuated PMBR, and this change could reflect a psychomotor slowing in clinical symptoms and cognitive functions.

Methods

Study design

This study adopted a cross-sectional case–control study design. Data, including demographic data, clinical assessments, neurocognitive assessments, MEG scan data and MRI scan data, were collected from patients with MDD and healthy controls (HCs).

Participants

The MDD patients were recruited from the Affiliated Brain Hospital of Nanjing Medical University between 2012 and 2021. All patients met the diagnostic criteria of major depressive disorder using the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR). The inclusion criteria for this population were: (1) aged 18–50 years; (2) right-handed; (3) native Han Chinese; (4) education level of junior high school or above; (3) Hamilton Rating Scale for Depression 17-item (HAMD17) > 17; (4) Young Mania Rating Scale (YMRS) [56] score < 5; (5) no structured psychotherapy or physical therapy within six months. The exclusion criteria included comorbidity with other mental or physical illnesses, history of substance abuse, contraindications for MEG or MRI and pregnancy or lactation.
One hundred thirty-two individuals, comprising 65 healthy controls and 67 MDD patients, were enrolled in this study. Participants were asked to perform a simple visuomotor task during MEG scanning. This work was approved by the Affiliated Brain Hospital of Nanjing Medical University. It was performed in accordance with the Declaration of Helsinki, and all individuals provided written informed permission before participation.

Clinical assessments

We collected general participant information, such as sex, age, education, ethnicity, dominant hand, disease history, marriage and family history. Depression severity was assessed using HAMD17, and manic symptoms were evaluated by YMRS. Based on factorial analysis found in Bertelli and the Istituto Superiore di Sanità (Italy 1977), and in the HAMD17 [57, 58], five structural factors included: (I) anxiety/somatization; (II) body weight; (III) cognitive disturbances; (IV) retardation; (V) sleep disturbances. Retardation factor measurement included depressed mood, work and interests, retardation and genital symptoms.

Neurocognitive assessments

Based on previous work, psychomotor alterations could be measured by neuropsychological tests [7]. In this study, psychomotor performance was measured by three different neuropsychological taskes:1) DSST, which measures both cognitive and motor elements of psychomotor by instructing subjects to fill in as many blanks as possible within 90 s according to the number symbol correspondence table. Test performance is evaluated by the number of successful completions [59]; 2) TMT-A, a test in which individuals are directed to draw lines through consecutive numbers to test processing speed. The time taken to complete the test represents task performance [60]; and 3) VFT, a task in which participants are asked to name as many animals or vegetables as possible in 60 s examining mental processing speed [61]. These tests can accurately quantify psychomotor changes in MDD patients.

MEG scanning

Subjects were placed in a magnetically shielded room during the entire experiment. Data were collected using a 275-channel CTF system (VSM Med Tech Inc., Port Coquitlam, Canada). The sampling rate is 1,200 Hz. The participants were lying in the MEG machine during a visuomotor task. Three coils, one nasion and two preauricular points were used to check head movements during the recording. Electrocardiography and electrooculography were also recorded. The experiment consists of two blocks, each lasting 5 min. Participants can take a small break between blocks.

Task paradigm

Participants were asked to perform a visuomotor task during MEG scanning. Participants responded with a right index finger button press to visual stimuli. Figure 2 shows an illustration of this paradigm. During each trial, grey light was exhibited on a projection screen for 2,500 ms, then a green light lasting 500 ms. Subjects responded with a right index finger button press to visual stimuli. Individuals were asked to concentrate on the projection screen, keep their bodies still, and press the button as quickly as possible. Participants first completed a practice examination to understand the task, followed by a formal exam including 180 trials.

MRI scanning

MRI data were recorded with a Siemens Verio 3 T MRI system. The parameters were the same as those used in our earlier articles [62]. Three markers were put in the same location as MEG to facilitate registration between MEG data and structural MRI in the following data analysis.

Data processing

The entire data processing process is illustrated in Fig. 3. The raw data were epoched into a time window (-0.7 to 2.3 s). The 0 s represent the emergence of a visual cue or green light. The data were down-sampled to 400 Hz. Then we applied Synthetic third-order gradiometer noise cancellation and removed linear trend and line interference with a 50-Hz band-stop filter. Visual artifact rejection was used to exclude trials and channels with high variation. Furthermore, with a visual examination, an independent component analysis (ICA) was used to eliminate eye artifacts, as well as cardiac and muscular components.
We analysed the MEG data in FieldTrip (version 20,210,720) [63]. The structural T1 data was imported and segmented using FieldTrip, with 250 anatomical volumes in each direction and “singleshell”.

Beamforming and time course extraction

As PMBR is located in the contralateral M1, we want to extract the beta time series of the M1 in this right finger tap task. Using the linearly constrained minimum variance (LCMV) beamformer [64], we can compute virtual channel time series at the locations of interest. The coordinates of the M1 were defined by the Automated Anatomical Labeling (AAL) template atlas [65]. The spatial filter was computed with the covariance and the forward model for the left M1. Using the spatial filters, virtual channel time series were obtained.

Time–frequency spectrograms

Using a Hanning taper-based time window of four cycles at each frequency, the source-level time–frequency representation of the time series of the M1 may be obtained (1–100 Hz in steps of 1 Hz). We compared the active power to the baseline using relative percentage. The baseline was defined between the -0.5–0 s window relative to the appearance of green light. The time–frequency spectrograms were averaged across participants in both groups.

PMBR quantification

We averaged mid-beta band (17–25 Hz) amplitude from the data baseline adjusted in time windows (1 < t < 2 s) acceptable for the PMBR. Eventually, we obtained a value per participant representing the PMBR at the left M1.

Statistical analyses

A two-sample t-test was used to check age and education, whereas chi-square tests were conducted to compare gender between MDD patients and HCs. All statistical analyses were done on SPSS 19.0 software (IBM Corp., Armonk, NY, USA). The differences in neurocognitive test performance (DSST, TMT-A and VFT) between the MDD and HC groups were compared by a two-sample t-test (two-tailed). The difference in PMBR amplitude between groups was analysed using a two-sample t-test. We then computed correlations between PMBR values and retardation factor, neurocognitive tests performance (DSST, TMT-A and VFT), controlling for age, sex and education. To avoid multiple comparison problems, further FDR correction was conducted using a special MATLAB function.

Results

Demographics and clinical characteristics

Sixty-seven MDD patients and sixty-five HCs were enrolled in the study. There was no significant difference in sex, age or education between the two groups. HAMD17 total score and retardation factor score were recorded for patients only (Table 1).

Group differences of PMBR

Figure 4A shows the time–frequency representations of the left M1 for the MDD and HC groups. We observed that PMBR appeared following MRBD in the HC group, which has been well-established by the work of others. The MMD group experienced a similar but weaker response compared to the HC group. The graph shows that beta amplitude increases around 1 s following the visual stimulus. The PMBR value in the MDD group was lower than that in the HC group (t = 3.70, p < 0.001) (Table 2, Fig. 4B).

Association between PMBR and clinical assessments

In the MDD group, a two-tailed Pearson’s partial correlation was performed to compare the PMBR values with retardation factor scores. Psychomotor alterations are reflective of items relating to exhaustion, energy loss, or lack of attention in HAMD17. So, the retardation factor in HAMD17 can partially represent psychomotor alterations. In MDD patients, we particularly focused on the retardation factor scores, and we found that the retardation scores were inversely correlated with PMBR (r = -0.365, p = 0.002). Moreover, given that healthy ageing has an impact on beta oscillations [3645], the correlations remained significant (r = -0.374, p = 0.006, FDR corrected) after controlling sex, age and education (Fig. 5A).

Association between PMBR and neurocognitive assessments

In the MDD group, partial correlation analysis revealed a significant positive correlation between the DSST scores and PMBR values (r = 0.411, p = 0.012, FDR corrected). Moreover, the TMT-A scores were negatively associated with PMBR (r = -0.451, p = 0.003, FDR corrected). The VFT scores were positively correlated with PMBR (r = 0.348, p = 0.022). However, this effect is no longer significant after controlling sex, age and education, and performing FDR correction (r = 0.348, p = 0.06, FDR corrected). Figure 5B and C visualise the relationship between neurocognitive assessments and PMBR amplitude. There was a significant negative correlation between age and PMBR in HCs (r = -0.300, p = 0.015). However, age was not significantly correlated with PMBR in MDD patients.

Discussion

Deficit in psychomotor function has been acknowledged as an essential feature of MDD for decades. However, despite its prevalence and impact, few studies have probed the neuronal mechanisms underlying these symptoms. In this study, we primarily explored the relevance of the abnormal motor-related oscillatory activity to the psychomotor alterations in patients with MDD using clinical assessments, neurocognitive tests and a simple visuomotor task during MEG recording. More specifically, MDD patients had slower psychomotor speed and attenuated PMBR activity than HCs. Furthermore, there was an association between psychomotor alterations and PMBR values in the MDD group. These findings support our earlier hypothesis that the strength of motor-related cortical oscillations impacts slowing mental and motor processes in MDD. In addition, there was a significant negative correlation between age and PMBR in HCs.
In line with earlier studies that MDD patients have diminished sensorimotor cortex activity [2], we found that MDD patients had lower PMBR in M1 at the end of movement than HCs in our visuomotor MEG study. Several explanations have been put forward to interpret PMBR. One of the theories is that PMBR is generated by the peripheral electrical stimulation of afferent pathways or somatosensory stimuli [66, 67], indicating afferent sensory feedback on the completion of the movement [30]. The somatosensory system is not only responsible for afferent input information but also actively communicates with the motor cortex during movement [68]. Poor sensory feedback may cause major problems with sensorimotor integration and reduce the accuracy of feedforward predictions[69]. The afferent sensory feedback could be applied to evaluate movement outcome, possibly impacting the following processing speed. The evidence from healthy individuals revealed that a “slowed movement state” displayed weaker sensorimotor beta dynamics [34] compared to fast movement [70]. More evidence has been provided that patients with motor abnormalities or processing speed slowing displayed attenuated PMBR. For example, Robson et al. found aberrant PMBR activity in SCH [50], as well as ASD [5355] and PD [4648]. Taken together with previous research, our results suggest that the reduced PMBR activity is characteristic of patients with aberrant psychomotor performance.
Furthermore, we did find that the PMBR activity is negatively associated with retardation factor scores in HAMD17, indicating that MDD patients with higher clinical retardation symptoms displayed weaker sensorimotor beta dynamics. The retardation factor in HAMD17 partly reflects psychomotor function [3], suggesting that retardation symptoms result from the dysfunction of motor-related brain areas in MDD [71, 72]. Northoff et al. aggregated available evidence in healthy subjects, MDD, BD and SCH, proposing three psychomotor mechanisms, including subcortical modulation of motor circuit, cortical modulation of motor circuit and balance between motor cortex activity and global cortical activity [2]. It is worth noting that all mechanisms lead to the motor cortex. In addition, a recent study found that reduced PMBR relates to the severity of mental disorganisation and impoverishment symptoms in SPD, which involves thought processing speed [52]. Collectively, these results suggested that the reduced PMBR activity in M1 is possibly one of the key nodes to illustrate the psychomotor alterations in MDD.
Moreover, our study also found that PMBR activity was associated with cognitive function in MDD. In our research, MDD patients performed worse on all three neurocognitive tests compared to HCs. Our findings are congruent with a prior meta-analysis, showing that MDD patients report impairments in motor speed, processing speed, executive functioning in tests with time limitations, and verbal fluency [73]. Consistently, the “time to peak” of the PMBR is associated with the DSST performance in multiple sclerosis (MS) patients [74]. Another study observed that PMBR was significantly correlated with DSST scores in patients with schizophrenia [51], providing strong evidence that PMBR activity could reflect information processing speed. Abnormal PMBR may represent aberrant sensory feedback. Patients with MDD thus have reduced feedback about the final outcomes of their motor actions, resulting in serious difficulties in sensorimotor integration and decreased certainty in the feedforward predictions that are based on the internal model. In addition, a reduced PMBR may reflect poor inhibition of motor cortex after movement termination in MDD. Overall, our study provides novel insights into neural mechanisms that are involved in psychomotor disturbances in MDD from the perspective of neural oscillations. This may lay the groundwork for novel biomarkers and individualised interventions for this difficult to treat feature of MDD.

Limitations

Of note, there are some limitations in this study. First, scales to measure psychomotor alterations in MDD should be used in future studies, such as the Motor Agitation and Retardation Scale (MARS), the CORE index of melancholia, and the Salpetriere Retardation Rating Scale (SRRS) [7577]. Second, PMBR is modulated by task duration [78] and is related to contraction force [79] and movement duration [80]. It will be better to control these factors in future studies. Thirdly, the current study only focused on M1. The impairments of cognitive function and clinical symptoms in MDD are caused not only by motor cortex dysfunction, but also by the coordination of distant brain areas. We will further explore the long-distance communication between brain regions in the next step.

Conclusion

Our present MEG study has expanded on previous literature by demonstrating that motor-related beta oscillations are weaker in patients with MDD than HCs during tasks involving psychomotor processes, reflecting difficulties in sensorimotor integration. Moreover, the current results provide direct electrophysiological evidence that the reduced PMBR activity contributes to clinical symptoms and cognitive functions in MDD, identifying a potential electrophysiological biomarker for assessing PMR. These electrophysiological imaging results offer a “Spatiotemporal Psychopathology” insight into abnormal psychomotor function suffered by MDD patients.
