Patients with severe acquired brain injury (SABI) may evolve towards different outcomes. The primary aim was to evaluate the clinical evolution of a large population of patients with SABI admitted to post-acute rehabilitation from 2001 to 2016, diagnosed with severe brain injury (GCS ≤ 8) in the acute phase and a coma duration of at least 24 h. The possible changes between the admission time to a post-acute rehabilitation hospital and the discharge time were measured by means of Glasgow Outcome Scale (GOS), Level of Cognitive Functioning (LCF), and Disability Rating Scale (DRS). ⋯ Data of 890 patients were analyzed (54% TBI, length of stay = 162 ± 186 days, GCS = 7.46 ± 1.28); time interval from the SABI (OR = 0.246, CI 95% = 0.181 - 0.333), scores at admission of LCF (OR = 2.243, CI 95% = 1.492 - 3.73), GOS (OR = 0.138, CI 95% = 0.071 - 0.266), DRS (OR = 0.457, CI 95% = 0.330 - 0.632), and etiology (OR = 2.273, CI 95% = 1.676 - 3.084) played a significant role (p < 0.001, explained variance 69.9%) for improving GOS score. Time interval from the SABI to admission in our post-acute rehabilitation ward (OR = 0.300, CI 95% = 0.179 - 0.501, p < 0.001), length of rehabilitation stay (OR = 2.808, CI 95% = 1.694 - 4.653, p < 0.001), and etiology (OR = 1.769, CI 95% = 1.095 - 2.857, p = 0.020) led to a statistically significant improvement in DRS (explained variance 91%). The most significant predictive factors for the outcome of patients with SABI were etiology, time interval from SABI to admission in rehabilitation, and length of rehabilitation stay.

The comorbidity of headache and epilepsy is often seen in neurological practice. The objective of this study was to assess the prevalence, types of, and risk factors for headache in juvenile myoclonic epilepsy (JME). We assessed a total of 200 patients and 100 healthy controls in our study. ⋯ However, migraine frequency was higher in JME patients than healthy controls. Some migraine and TTH characteristics were different in between groups. We suggest that our results support both genetic relationship and shared underlying hypothetical pathopysiological mechanisms between JME and headache, especially migraine.

Pain is one of the most disabling clinical symptoms in patients with multiple sclerosis (MS). Several studies have already assessed the prevalence of pain in MS patients, reporting variable results, probably due to methodological differences. The aim of this single-centre cross-sectional study was to define the prevalence and characteristics of chronic pain in a population of MS patients using validated tools, and to analyse these data in relation to demographic and clinical features, including disease duration and disability (EDSS and its single functional system scores). ⋯ Patients with chronic pain and, in particular, patients with neuropathic pain had significantly higher EDSS scores than those without pain. Only 24% of patients with chronic pain and 33% of patients with neuropathic pain were on a specific long-lasting treatment for pain. The present study supports the routine assessment of neuropathic pain in MS patients, especially in those with a sensory functional system involvement, in order to avoid underdiagnosing and undertreating a potentially disabling condition.

We hypothesized the filtering of sensory input from face and hand at brainstem may reorganize in hemifacial spasm (HFS) and postparalytic facial syndrome (PFS). Thus, we examined the prepulse inhibition of blink reflex (BR-PPI) in HFS and PFS. We included 12 healthy subjects, 13 patients with HFS, and 11 patients with PFS. ⋯ BR-PPI was decreased on both sides of patients. The mean R2 recovery was higher on both sides of patients with HFS and PFS (p = 0.007). Filtering of facial sensory input is decreased probably to monitor and to correct the sequence of facial movements in these disorders.

Observational Study
Right-to-left shunt may be prone to affect the white matter integrity of posterior circulation in migraine without aura.
Numerous studies have indicated an association between migraine and right-to-left shunt. However, little is known about whether right-to-left shunt has an effect on the migraine brain. This observational study aims to explore the impact of right-to-left shunt on the brain of migraine without aura on microstructural level. ⋯ No significant differences were observed in values of fractional anisotropy and axial diffusivity. No significant between-group differences were found in gray matter volume. Right-to-left shunt may cause alterations of white matter integrity in migraine without aura, and the alterations are more likely to be located at the posterior circulation.
