Purpose: To investigate the opinions of physicians about brain surgery for drug-resistant epilepsy worldwide.Methods: Practicing neurologists, psychiatrists, and neurosurgeons from around the world were invited to participate in an online survey. The survey anonymously collected data about demographics, years in clinical practice, discipline, nation, work setting, and answers to the questions about beliefs and attitudes about brain surgery for drug-resistant epilepsy.Results: In total, 1410 physicians from 20 countries and different world regions participated. The propensity to discuss brain surgery with patients, who have drug-resistant seizures, was higher among men (versus women) [Odds Ratio (OR) 1.67, 95% CI 1.20-2.31; p = 0.002]. In comparison to neurologists, psychiatrists were less likely (OR 0.28, 95% CI 0.17-0.47; p < 0.001) and neurosurgeons were more likely (OR 2.00, 95% CI 1.08-3.72; p = 0.028) to discuss about it. Survey participants working in Africa, Asia, the Middle East, and the Former Union of Soviet Socialist Republics showed a lower propensity to discuss epilepsy surgery with patients.Conclusion: This study showed that on an international level, there is still a knowledge gap concerning epilepsy surgery and much needs to be done to identify and overcome barriers to epilepsy surgery for patients with drug-resistant seizures worldwide.

To investigate whether the positional release technique (PRT) affects central sensitization in patients with chronic tension-type headache (TTH). Randomized controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. Two university neurology clinics. Patients (N=32) with TTH and myofascial trigger points (MTrP) in their cervical muscles. Patients in the PRT group received 10 treatment sessions for each of their MTrPs over the course of 5 weeks. All participants could use ibuprofen 200 mg for their headaches during the study. The primary outcome measure was brain metabolite profile. The secondary outcome measures were headache frequency and intensity, McGill score, and pressure pain threshold (PPT), which were evaluated in each participant during 5 weeks with proton magnetic resonance spectroscopy, patients' self-reports, the McGill Pain Questionnaire, and a pressure algometer. Analysis of the data from 26 patients showed that headache frequency (P =.001), headache intensity (P =.002), McGill score (P =.003), and local PPT (P =.003) changed significantly after PRT. The myo-inositol/creatine concentration ratio in the somatosensory cortex (P =.041) decreased significantly in the control group. Furthermore, there were significant differences between groups in headache frequency (P <.001), headache intensity (P <.001), McGill score (P <.001), local PPT (P =.004), distal PPT (P =.041), and glutamate–glutamine/creatine concentration ratio in the thalamus (P =.014). These findings indicate that PRT did not affect central sensitization in patients with TTH despite the improvement in clinical symptoms. [ABSTRACT FROM AUTHOR]

Objectives: There are several reports of the association between SARS-CoV-2 infection (COVID-19) and cerebral venous sinus thrombosis (CVST). In this study, we aimed to compare the hospitalization rate of CVST before and during the COVID-19 pandemic (before vaccination program).Materials and Methods: In this retrospective cohort study, the hospitalization rate of adult CVST patients in Namazi hospital, a tertiary referral center in the south of Iran, was compared in two periods of time. We defined March 2018 to March 2019 as the pre-COVID-19 period and March 2020 to March 2021 as the COVID-19 period.Results: 50 and 77 adult CVST patients were hospitalized in the pre-COVID-19 and COVID-19 periods, respectively. The crude CVST hospitalization rate increased from 14.33 in the pre-COVID-19 period to 21.7 per million in the COVID-19 era (P = 0.021). However, after age and sex adjustment, the incremental trend in hospitalization rate was not significant (95% CrI: -2.2, 5.14). Patients > 50-year-old were more often hospitalized in the COVID-19 period (P = 0.042). SARS-CoV-2 PCR test was done in 49.3% out of all COVID-19 period patients, which were positive in 6.5%. Modified Rankin Scale (mRS) score ≥3 at three-month follow-up was associated with age (P = 0.015) and malignancy (P = 0.014) in pre-COVID period; and was associated with age (P = 0.025), altered mental status on admission time (P<0.001), malignancy (P = 0.041) and COVID-19 infection (P = 0.008) in COVID-19 period.Conclusion: Since there was a more dismal outcome in COVID-19 associated CVST, a high index of suspicion for CVST among COVID-19 positive is recommended.

Abstract: Purpose: We investigated the various possible reasons for uncontrolled seizures in patients 18 years of age and older to determine the impact of pseudointractability. We also tried to investigate the various forms of pseudointractability. Methods: In this cross-sectional study, all patients 18 years of age and older with their first seizure occurring at least six months prior to the referral date, taking at least one antiepileptic drug (AED) and having at least one seizure in the past three months were studied. The presumed reason for uncontrolled seizures was arbitrarily considered to be one of these five categories: Poor compliance; Wrong medication (misclassification); Wrong dose of the correct medication; Diagnosis other than epilepsy; and finally, Medically-refractory epilepsy. Statistical analyses were performed using Chi-square and Fisher''s Exact tests, and a P value less than 0.05 was considered significant. Results: 350 patients were referred to us due to uncontrolled seizures. One hundred ninety-one (55%) were male and 159 (45%) were female. Twelve percent of the patients had diagnoses other than epilepsy, 40% had indeed medically-refractory epilepsy; 29% were taking the wrong AEDs (misclassified epilepsy); 18% were taking suboptimal doses of AEDs; and 1% had poor drug compliance. The most common reason for uncontrolled seizures among patients with idiopathic generalized epilepsy was taking the wrong AED. However, among patients with focal epilepsy, true medically-refractory epilepsy was the most common reason. Conclusion: Uncontrolled seizures are a commonly encountered problem, especially at epilepsy clinics and one should consider all possible reasons for these uncontrolled seizures. The mainstay for making a correct diagnosis is a detailed clinical history. [Copyright &y& Elsevier]

Abstract: Tension Type Headache (T.T.H) is the most prevalent headache. Myofascial abnormalities & trigger points are important in this type of headache which can be managed by Positional Release Therapy (PRT). This is a report of a 47 years old female patient with Tension Type Headache treated by Positional Release Therapy for her trigger points. She had a constant dull headache, which continued all the day for 9 months. A physiotherapist evaluated the patient and found active trigger points in her cervical muscles. Then, she received Positional Release Therapy for her trigger points. After 3 treatment sessions, the patient''s headache stopped completely. During the 8 months following the treatment she was without pain, and did not use any medication. Positional Release Therapy was effective in treating Tension Type Headache. This suggests that PRT could be an alternative treatment to medication in patients with T.T.H if the effectiveness of that can be confirmed by further studies. [ABSTRACT FROM AUTHOR]

Around 40%–70% of patients with multiple sclerosis (MS) may experience cognitive impairments during the course of their disease with detrimental effects on social and occupational activities. Transcranial direct current stimulation (tDCS has been investigated in pain, fatigue, and mood disorders related to MS, but to date, few studies have examined effects of tDCS on cognitive performance in MS. The current study aimed to investigate the effects of a multi-session tDCS protocol on cognitive performance and resting-state brain electrical activities in patients with MS. Twenty-four eligible MS patients were randomly assigned to real (anodal) or sham tDCS groups. Before and after 8 consecutive daily tDCS sessions over the left dorsolateral prefrontal cortex (DLPFC), patients' cognitive performance was assessed using the Cambridge Brain Sciences-Cognitive Platform (CBS-CP). Cortical electrical activity was also evaluated using quantitative electroencephalography (QEEG) analysis at baseline and after the intervention. Compared to the sham condition, significant improvement in reasoning and executive functions of the patients in the real tDCS group was observed. Attention was also improved considerably but not statistically significantly following real tDCS. However, no significant changes in resting-state brain activities were observed after stimulation in either group. Anodal tDCS over the left DLPFC appears to be a promising therapeutic option for cognitive dysfunction in patients with MS. Larger studies are required to confirm these findings and to investigate underlying neuronal mechanisms. [ABSTRACT FROM AUTHOR]
