The present results show that the analgesic effects of 'conventional' 10 Hz-rTMS delivered to M1 can be enhanced by TBS priming, at least using iTBS. Interestingly, the application of cTBS and iTBS did not produce opposite modulations, unlike previously reported in other systems. It remains to be determined whether the interest of TBS priming is to generate a simple additive effect or a more specific process of cortical plasticity.

Introduction. The management of neuropathic pain remains complex, generally because of the psychiatric comorbidity that is often underdiagnosed. The objectives of our work were to determine the link between depression and the characteristics of NP on the one hand and quality of life on the other hand, in a sample of subjects consulting for neuropathic pain (NP) regardless of etiology. Methods. We conducted a cross-sectional study involving 61 neuropathic pain consulting patients in whom we assessed five parameters, namely, neuropathic pain based on DN4, pain intensity using EVA, anxiety, and depression according to the HADS and quality of life. Results. The study population mean age was 52.71 ± 14.29 years while the sex ratio (m/f) was 0.52. The neuropathic pain’s most common etiologies were postherpetic pain, carpal tunnel syndrome, and diabetic neuropathy. Depression and anxiety prevailed by 65.6% and 73.7%, respectively. The quality of life was impaired with average SF-12 physical and mental scores of 33.76 ± 8.03 and 37.78 ± 11.52, respectively. The overall mean BPI score was 5.53 ± 1.76. Patients with high DN4 scores were significantly more depressed (p=0.025). A significantly positive association was found between the depression score and the pain intensity (p=0.001, r = 0.41). Depressed subjects had a poor quality of life according to SF-12 and BPI. Conclusion. Given the depressive comorbidity impact on the neuropathic pain components as well as the quality of life, screening for this comorbidity should be part of the baseline ND assessment.

Noninvasive cortical stimulation (NICS) has been used during the acute, postacute and chronic poststroke phases to improve motor recovery in stroke patients having upper- and/or lower-limb paresis. This paper reviews the rationale for using the different NICS modalities to promote motor stroke rehabilitation. The changes in cortical excitability after stroke and the possible mechanisms of action of cortical stimulation in this context are outlined. A number of open and placebo-controlled trials have investigated the clinical effect of repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) of the primary motor cortex in patients with motor stroke. These studies attempted to improve motor performance by increasing cortical excitability in the stroke-affected hemisphere (via high-frequency rTMS or anodal tDCS) or by decreasing cortical excitability in the contralateral hemisphere (via low-frequency rTMS or cathodal tDCS). The goal of these studies was to reduce the inhibition exerted by the unaffected hemisphere on the affected hemisphere and to then restore a normal balance of interhemispheric inhibition. All these NICS techniques administered alone or in combination with various methods of neurorehabilitation were found to be safe and equally effective at the short term on various aspects of poststroke motor abilities. However, the long-term effect of NICS on motor stroke needs to be further evaluated before considering the use of such a technique in the daily routine management of stroke.

Objectives. To estimate the prevalence of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) in a population aged over sixty years with type 2 diabetes and to study the impact of anxiety and depression on glycemic balance and disease outcome. Results. The prevalence of anxiety and depression in the 62 subjects included in the study was, respectively, 40.3% and 22.6%. We found a relationship between these disorders and complicated diabetes. The subjects having an imperfectly balanced diabetes had a higher average anxiety score than those having a good glycemic control (9.1 ± 4.2 versus 6.5 ± 3.1; P = 0.017). No relationship was found between diabetes balance and depression. Conclusion. Association between anxiety and depressive disorders and diabetes is frequent and worsens patients' outcome, in terms of diabetes imbalance as well as in terms of diabetic complications. Our study shows that there is need for physicians to detect, confirm, and treat anxiety and depressive disorders in elderly diabetic patients.
