RAGT improved the walking competencies in non-autonomous ambulant patients with MS, with benefits in terms of perceived fatigue.
The International Classification of Headache Disorders does not separate the moderate from severe/very severe traumatic brain injury (TBI), since they are all defined by Glasgow coma scale (GCS) < 13. The distinction between the severe and very severe TBI (GCS < 8) should be made upon coma duration that in the latter may be longer than 15 days up to months in the case of vegetative state. Post-traumatic amnesia duration may double the coma duration itself. Therefore, the 3-month parameter proposed to define the occurrence or resolution of post-traumatic headache (PTH) appears inadequate. Following TBI, neuropathic pain, central pain, thalamic pain, combined pain are all possible and they call for proper pharmacological approaches. One more reason for having difficulties in obtaining information about headache in the early phase after regaining consciousness is the presence of concomitant medications that may affect pain perception. Post-traumatic stress disorder (PTSD) develops days or weeks after stress and tends to improve or disappear within 3 months after exposure; interestingly, this spontaneous timing resembles that of PTH. In our experience the number of TBI patients with PTH at 1-year follow-up is lower in those with longer coma duration and more severe TBI. Cognitive functioning evaluated after at least 12 months from TBI, showed mild or no impairment in these patients with severe TBI and PTH, whereas they have psychopathological changes, namely anxiety and depression. The majority of patients with PTH after severe/very severe TBI had skull fractures or dural lacerations and paroxystic EEG abnormalities. The combination of psychological changes (depression and anxiety) and organic features (skull fractures, dural lacerations, epileptic EEG abnormalities) in PTH may be inversely correlated with the severity of TBI, with prevalence of psychological disturbances in mild TBI and of organic lesions in severe TBI. On the other hand, only in severe TBI patients with good cognitive recovery the influence of the psychopathological disorders may play a role. In fact, the affective pain perception is probably related to the integrity of cognitive functions as in mild TBI and in severe TBI with good cognitive outcome.
The benefits of surgical correction of moderate internal carotid artery stenosis have been demonstrated only in symptomatic subjects. It is debatable whether patients with lacunar infarct ipsilateral to a moderate carotid stenosis may be considered symptomatic like those with large-artery stroke. The aim of the study was to seek markers capable of differentiating patients with lacunar or non-lacunar stroke ipsilateral to a moderate internal carotid artery stenosis. We enrolled 95 patients with a first stroke ipsilateral to a moderate (50-69 %) stenosis of the internal carotid artery and divided them into lacunar and non-lacunar stroke based on clinical presentation and neuroradiological findings; 34 subjects with asymptomatic moderate carotid stenosis and 31 normal individuals were also studied. Baseline characteristics; risk factors, cerebrovascular reactivity to hypercapnia evaluated by means of the breath-holding index (BHI), the presence and severity of carotid stenosis and intimamedia thickness (IMT) of the common carotid arteries were determined. There were 36 patients with lacunar and 59 with non-lacunar stroke. Degree of stenosis, and IMT and BHI ipsilateral to symptomatic stenosis were found to be significant independent predictors as each 10 % increase of stenosis carried a 4.3 higher probability of non-lacunar stroke (95 % CI: 1.91-9.51); each decimillimeter increment in IMT increased this probability by 1.45 (95 % CI: 1.10-1.92); and the risk odds ratio associated with each 0.1 increase in BHI was 1.88 (95 % CI: 1.33-2.66). A decrease in BHI of 0.1 thus carried a 90% greater probability of having a lacunar stroke. The results show that patients with moderate internal carotid artery stenosis and lacunar stroke can be differentiated from those with non-lacunar stroke on the basis of distinctive ultrasonographic findings. Further studies are needed to clarify whether our findings have pathogenetic implications and may be of help for the planning of different therapeutic strategies in patients with moderate internal carotid stenosis and lacunar or non-lacunar ipsilateral stroke.
To study the functional connectivity in patients with severe acquired brain injury is very challenging for their high level of disability because of a prolonged period of coma, extended lesions, and several cognitive and behavioral disorders. In this article, we investigated in these patients the default mode network and somatomotor connectivity changes at rest longitudinally, in the subacute and late phase after brain injury. The aim of the study is to characterize such connectivity patterns and relate the observed changes to clinical and neuropsychological outcomes of these patients after a period of intensive neurorehabilitation. Our findings show within the default mode network a disruption of connectivity of medial pre-frontal regions and a significant change of amplitude of internal connections. Notably, strongest changes in functional connectivity significantly correlated to consistent clinical and cognitive recovery. This evidence seems to indicate that the reorganization of the Default Mode Network may represent a valid biomarker for the cognitive recovery in patients with severe acquired brain injury.
Objective: The aim of this study was to evaluate the effectiveness of cognitive rehabilitation in a group of multiple sclerosis (MS) patients. Methods: Thirty-four patients were included in this study and randomly allocated either to treatment with multidisciplinary rehabilitation plus cognitive training or to treatment with multidisciplinary rehabilitation alone. Results: After 3 months of cognitive treatment, the patients assigned to the rehabilitation plus cognitive training group displayed an improvement in the cognitive test of executive function and a marked improvement in quality of life (QoL). The patients treated with multidisciplinary rehabilitation without cognitive training improved in the physical composite score alone. Both groups of patients displayed an improvement in depression, though the improvement was confirmed at the 6-month follow-up examination (p = 0.036) only in patients treated with multidisciplinary rehabilitation plus cognitive training. Conclusions: Our results indicate that the multidisciplinary rehabilitation treatment is the best approach to treat MS. The specific effect of each treatment needs to be assessed to be able to determine its role within a multidisciplinary approach. Cognitive rehabilitation is an important aspect of this multidisciplinary approach insofar as it may improve the QoL of MS people.
Background: Lower thermal and discomfort thresholds may predispose multiple sclerosis (MS) patients to chronic pain, but a possible effect of fibromyalgia (FM) comorbidity has never been investigated. Aims were to investigate the thermal and discomfort thresholds in the evaluation of pain intensity between MS patients with FM (PFM+) and MS patients with pain not associated to FM (PFM−). Methods: One hundred thirty three MS patients were investigated for chronic pain. FM was assessed according to the 1990 ACR diagnostic criteria. An algometer was used to measure the thresholds in the patients and 60 matched healthy subjects. Results: Chronic pain was present in 88 (66.2%) patients; 12 (13.6%) had neuropathic pain, 22 (17.3%) were PFM+ and 65 (48.9%) PFM−. PFM+ were predominantly female (p = 0.03) and had a greater EDSS (p = 0.01) than NoP; no other significant differences emerged than PFM−. The thresholds were lower in MS patients than controls (p < 0.01), mainly in the PFM+. FM severity influenced the thermal threshold (p < 0.001), while the female gender influenced the discomfort threshold (p < 0.001). Conclusion: Thermal and discomfort thresholds were lower in patients than controls and were the lowest in PFM+. Their more severely impaired thermal threshold supports a neurophysiological basis of such association.
