Purpose
Patients affected with multiple sclerosis suffer from depression more frequently than the general population. Beyond psychosocial, genetic and immune-inflammatory factors, also the brain ...damage which is peculiar of multiple sclerosis has been claimed to have a role in the aetiology of depression in those patients. The study of this interesting relation has been implemented with both conventional and advanced magnetic resonance imaging techniques. The aim of this review is to provide a historical perspective on the link between multiple sclerosis-related depression and structural and functional brain damage.
Methods
In this review, the results of the MRI studies regarding multiple sclerosis-related brain damage and the presence of depression are presented.
Results
The findings of the reports reveal a link between brain pathology and depressive symptoms or the diagnosis of depression in multiple sclerosis.
Conclusions
Although a multifactorial aetiology has been theorized for depression and depressive symptoms in patients with multiple sclerosis, this review supports the hypothesis that the structural and functional brain impairment might substantially be amongst those factors. Thus, depression itself might be a symptom with a neuro-biological basis and not only the consequence of the disability derived from the neurological impairment.
The number of robot-assisted minimally invasive surgeries is increasing annually, together with the need for dedicated and effective training. Surgeons need to learn how to address the novel control ...modalities of surgical instruments and the loss of haptic feedback, which is a common feature of most surgical robots. High-fidelity physical simulation has proved to be a valid training tool, and it might help in fulfilling these learning needs. In this regard, a high-fidelity sensorized simulator of vascular structures was designed, fabricated and preliminarily validated. The main objective of the simulator is to train novices in robotic surgery to correctly perform vascular resection procedures without applying excessive strain to tissues. The vessel simulator was integrated with soft strain sensors to quantify and objectively assess manipulation skills and to provide real-time feedback to the trainee during a training session. Additionally, a portable and user-friendly training task board was produced to replicate anatomical constraints. The simulator was characterized in terms of its mechanical properties, demonstrating its realism with respect to human tissues. Its face, content and construct validity, together with its usability, were assessed by implementing a training scenario with 13 clinicians, and the results were generally positive.
Cognitive impairment affects 34-65% of People with Multiple Sclerosis (PwMS), significantly impacting their quality of life. Clinicians routinely address cognitive deficits with in-clinic ...neuro-behavioural interventions, but accessibility issues exist. Given these challenges, coupled with the lifelong need for continuous assistance in PwMS, researchers have underscored the advantageous role of telerehabilitation in addressing these requirements. Nonetheless, the feasibility and efficacy of home-based cognitive remediation remain to be firmly established. In this narrative review, we aimed to investigate the feasibility and efficacy of digital telerehabilitation for cognition in PwMS. Thirteen relevant studies were identified and carefully assessed. Regarding the feasibility of cognitive telerehabilitation, evidence shows adherence rates are generally good, although, surprisingly, not all studies reported measures of compliance with the cognitive training explored. Considering the efficacy of rehabilitative techniques on cognitive performance in PwMS, findings are generally inconsistent, with only one study reporting uniformly positive results. A range of methodological limitations are reported as potential factors contributing to the variable results. Future research must address these challenges, as more rigorous studies are required to draw definitive conclusions regarding the efficacy of home-based cognitive remediation in PwMS. Researchers must prioritise identifying optimal intervention approaches and exploring the long-term effects of telerehabilitation.
Multiple sclerosis (MS) refers to chronic inflammation of the central nervous system including the brain and spinal cord. Assessing for the presence of dysphagia in subjects with MS represents a ...challenge for neurologists in clinical practice. The aim of the present study was to verify the relationship between DYMUS scores, a patient-reported scale, and objective symptoms using the Dysphagia Outcome Severity Score (DOSS), based on fiber-optic endoscopy. Data were collected in a multicenter study. Two hundred and fifteen MS patients were enrolled, irrespective of self-reported dysphagia. DOSS revealed dysphagia in 122 subjects (56.7%). Compared with non-dysphagic subjects, the presence of dysphagia was related to more severe disability, longer disease duration, and a progressive form of the disease. A DYMUS score of 0 strongly correlated with a DOSS of 6 (sensitivity 100%) while DYMUS score of > 2 correlated with a DOSS < 7 (specificity 82%) of the self-reported scale. The DYMUS questionnaire can be a useful clinical tool for red-flagging patients who should undergo objective testing and referral to a otorhinolaryngologist.
Patients with traumatic brain injury often have balance and attentive disorders. Video game therapy (VGT) has been proposed as a new intervention to improve mobility and attention through a ...reward-learning approach. In this pilot randomized, controlled trial, we tested the effects of VGT, compared with a balance platform therapy (BPT), on balance, mobility and selective attention in chronic traumatic brain injury patients.
We enrolled chronic traumatic brain injury patients (n = 21) that randomly received VGT or BPT for 3 sessions per week for 6 weeks. The clinical outcome measures included: i) the Community Balance & Mobility Scale (CB&M); ii) the Unified Balance Scale (UBS); iii) the Timed Up and Go test (TUG); iv) static balance and v) selective visual attention evaluation (Go/Nogo task).
Both groups improved in CB&M scores, but only the VGT group increased on the UBS and TUG with a between-group significance (p < 0.05). Selective attention improved significantly in the VGT group (p < 0.01).
Video game therapy is an option for the management of chronic traumatic brain injury patients to ameliorate balance and attention deficits.

Depressive disorders are common in patients with multiple sclerosis, influencing their quality of life and adherence to treatments, as well as becoming more frequent with the progression of the ...disease and in the secondary progressive form of multiple sclerosis. Patients with multiple sclerosis often experience a typical cluster of symptoms in association with depression, such as fatigue, pain and cognitive impairment. However, the pathogenesis of multiple sclerosis-related depression remains partially unclear, even though genetic, immune-inflammatory and psychosocial factors might be seen to play a role, in addition to the brain structural alterations documented by magnetic resonance imaging studies. The high incidence and burden of depression in people affected with multiple sclerosis are matters of crucial importance. Despite such importance, the efficacy of pharmacologic treatments has been poorly studied and, for the most part, the access to non-pharmacological treatments is partially dependent on the local health system availability. It has been determined that interferon-beta and glatiramer acetate do not cause depressive symptoms; however, no definitive data in this regard are avaible for the newer disease-modifyng medications. In this review, we discuss the diagnosis, prevalence, pathogenesis, clinical aspects, magnetic resonance imaging findings and treatments available in patients experiencing multiple sclerosis-related depression.
The aim of the study was to explore the cognitive functions of a large sample of hospitalised subjects with mild symptomatic Coronavirus Disease (COVID-19) who were previously independent at home and ...without neurological diseases.
Patients admitted in a COVID-19 Unit for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection between November 2020 and March 2021 were recruited. Inclusion criteria were: being independent at home before the infection, radiologically confirmed COVID-19 pneumonia, positive reverse transcriptase-polymerase chain reaction nasopharyngeal swab and no oxygen supplementation at the time of evaluation. Exclusion criteria: cognitive impairment or neurological diseases previous to the infection, delirium episodes, and history of any mechanical ventilation use. They were evaluated with Montreal Cognitive Assessment (MoCA), Hamilton Depression Rating Scale (HAM-D) and Hamilton Anxiety Rating Scale (HAM-A).
Out of 522 subjects admitted in the COVID-19 Unit, 90 were enrolled mean age = 68.32(11.99); 46M/44F. An impaired MoCA (cut-off < 23) was found in 60 subjects (66.66 %). Pathological scores were obtained by 36.7 % of the subjects with <65 years and 78.3 % of those older than 65 years. A high prevalence of executive function and memory impairment was detected.
The results underline a high rate of cognitive impairment in previously independent mild COVID-19 patients. This might represent a potential threat for the everyday independence of these patients due to the consequences on everyday life activities and work following discharge from hospital. These subjects should, therefore, be monitored in order to allow a better understanding of the progression and consequences of the so-called “Long COVID”.
