RESUMEN
The COVID-19 pandemic has infected more than 22 million people worldwide. Although much has been learned about COVID-19, we do not know much about its neurological features and their outcome. This observational study was conducted on the patients of Imam Hossein Hospital, and 361 adult patients (214 males) with confirmed diagnosis of COVID-19 from March 5, 2020 to April 3, 2020, were enrolled. Data was gathered on age, sex, comorbidities, initial symptoms, symptoms during the disease course, neurological symptoms, and outcome. The mean age of the patients was 61.90 ± 16.76 years. The most common initial symptoms were cough, fever, and dyspnea. In 21 patients (5.8%), the initial symptom was neurological. History of dementia was associated with severe COVID-19 disease (odds ratio = 1.28). During the course of the disease, 186 patients (51.52%) had at least one neurological symptom, the most common being headache (109 [30.2%]), followed by anosmia/ageusia (69, [19.1%]), and dizziness (54, [15%]). Also, 31 patients had neurological complications (8.58%). Anosmia, ageusia, dizziness, and headache were associated with favorable outcome (P < 0.001), while altered mental status and hemiparesis were associated with poor outcome. The mortality rate of patients who had neurological complications was more than twice than that of patients without neurological complication (P = 0.008). Almost half of the patients experienced at least one neurological symptom, which may be the initial presentation of COVID-19. Dementia appears to be associated with severe COVID-19. Mortality was higher in patients with neurological complications, and these patients needed more intensive care.

BACKGROUND: Sleep disturbance is a frequent finding in patients with epilepsy. As evaluation of sleep disorders and quality of sleep in patients with epilepsy may provide better management of these patients, we aimed to assess the prevalence of common sleep disorders in patients with epilepsy. METHODS: Patients with epilepsy referred to an outpatient epilepsy clinic in Tehran during one year were included. Validated Persian questionnaires were used by an interviewer to assess Excessive daytime sleepiness (EDS), Restless leg syndrome (RLS), and insomnia. Also, patients' demographic features and clinical seizure-related characteristics were recorded. RESULTS: Seventy patients (35 males) aged between 18 and 75 were enrolled. Among patients, 61.4, 35.7, and 28.6% suffered from insomnia, EDS, and RLS, respectively (mild to severe). When considering seizure characteristics, there was no significant correlation between either seizure frequency or its type and the prevalence of sleep disturbance (although sleep disturbance was more common among patients with higher seizure frequency and patients with generalized seizure). Interestingly, age had a positive correlation with EDS. CONCLUSION: This study showed that sleep disturbance is a common finding in patients with epilepsy, which may become severe in some cases. Taking this into consideration, we suggest that routine evaluation of sleep disorders may help physicians to boost patients' sleep quality.

OBJECTIVES: COVID-19 disproportionately affects older adults and individuals with cardiovascular co-morbidities. This report presents fifteen patients who had COVID-19 respiratory illness followed by cerebrovascular events. MATERIALS AND METHODS: A call by the Iranian Neurological Association gathered cases across the country who developed neurological symptoms attributed to hemorrhagic or ischemic stroke after a definite or probable Covid-19 respiratory illness. Definite cases were those with a typical respiratory illness, positive nasopharyngeal Covid-19 PCR test, and chest CT consistent with Covid-19 infection. Probable cases were defined by a typical respiratory illness, history of contacts with a Covid-19 case, and chest CT characteristic for Covid-19 infection. RESULTS: Fifteen patients (12 men and 3 women) with an age range of 38 to 93 years old (median: 65 years old) were included. Fourteen patients had a first-ever acute ischemic stroke and one patient had a subarachnoid hemorrhage. Eleven patients (73%) had previous cardiovascular comorbidities. The median time between respiratory symptoms and neurological symptoms was seven days (range 1-16 days). Stroke severity in two patients was mild (NIHSS ≤ 6), in six patients moderate (NIHSS: 7-12), and in seven patients severe (NIHSS ≥13). One patient received intravenous tissue plasminogen activator ( IV-tPA) with improved neurological symptoms. Six out of 15 patients (40%) died. All but one of those who survived had significant disability assessed by a modified ranking scale >2. The majority of patients in this case series had vascular risk factors and their stroke was associated with severe disability and death. CONCLUSION: This report highlights the need for further investigation of the links between Covid-19 and cerebrovascular events.

Multiple sclerosis (MS) is an autoimmune-type inflammatory disorder in human central nervous system. Recombinant interferon beta (IFN-ß) decreases the number of relapses and postpones disability progression in MS. However, up to 50% of patients treated with interferon beta continue experiencing relapses and/or worsening disability. Single nucleotide polymorphisms in different genes have been known to show significant associations with response to IFN-ß in MS patients. In the present work, we examined the potential role of TRAILR1 and GRIA3 genes polymorphisms on response to IFN-ß therapy in Iranian MS patients. The DNA was extracted from blood samples by standard procedures from 73 patients diagnosed with Multiple Sclerosis that were either responded to IFN-ß or did not. We carried out RFLP -PCR and tetra-primer ARMS-PCR methods to study of rs20576 and rs12557782, respectively. All results were analyzed using the SPSS software. TRAILR1 rs20576 genotype frequencies in responders and non-responders were similar (χ2 = 0.26, P = 0.87, Fisher, s Exact test). Our results showed that response to IFN-ß has not association with sex (p = 0.73). Also, genotypic frequencies of GRIA3 rs12557782 had no significant differences between two groups of female population (χ2 = 3.75, p = 0.15). Furthermore, it had not been any statistical differences between responder and non-responder males (χ2 = 0.7, p = 0.4) related to the SNP. Our results analysis revealed no significant association between the studied SNPs (TRAILR1 rs20576 and GRIA3rs 12,557,782) and response to IFN-ß in Iranian MS patients.

PURPOSE: Multiple sclerosis (MS) requires long-term therapy and can affect many aspects of a patient's life, including quality of life. MS patients score lower on health-related quality of life (HRQoL) measures. The efficacy of subcutaneous interferon (IFN) ß-1a has been extensively evaluated by using objective measures but its impact on HRQoL is currently unclear. In this observational study, we evaluated HRQoL of Iranian patients with relapsing-remitting MS (RRMS) treated with IFN ß-1a by using short-form 36 (SF-36) and multiple sclerosis international quality of life (MusiQoL) questionnaires. METHODS: Four hundred recruited RRMS patients were treated with human serum album free IFN ß-1a for 1 year. Patients were required to fill in SF-36 and MusiQoL questionnaires at the first visit and at each follow-up visit. Expanded disability status scale (EDSS) evaluation was performed at baseline and at each visit. Comparisons in HRQoL between visits were calculated using Cohen's d effect size. The relationship between change in EDSS score and the score of each questionnaire was calculated using Pearson correlation coefficients. RESULTS: Three-hundred and eighty three completed the study. Two-hundred and thirty nine were female. Mean (SD) age was 28.75 (±5.49). After 1 year, overall MusiQoL Index score effect size was -0.16 and SF-36 physical component and mental component showed overall effect sizes of -0.28 and -0.53, respectively. Mean (range) EDSS change was 1 (1-4). Three-hundred and seventy four were clinically stable with mean (range) EDSS change of 0.1 (-2-0.5). Increase in EDSS was linked to a decrease in both MusiQoL and SF-36. CONCLUSION: We found that, HRQoL did not change significantly over the first year of therapy. Furthermore, decreases in HRQoL were inversely correlated with increases in EDSS score.

The current study aimed to examine whether high family functioning mitigates the association between headache intensity and distress. The sample consisted of 124 patients with chronic or recurrent headache. Patients completed validated questionnaires about headache intensity, family functioning, and distress. Hierarchical regression analyses were performed to examine the interaction between headache intensity and family functioning on distress. Headache intensity was positively associated with distress (r = .28, p = .002). As hypothesized, family functioning moderated this association (B = -.01, p = .023). More specifically, the positive association between headache intensity and distress was significant only among patients with lower family functioning (B = .01, p < .001) and not among patients with higher levels of family functioning (B = .006, p = .075). Functional families appear to buffer the distress level in patients; they showed relatively low levels of distress regardless of the severity of their headache. In contrast, patients with dysfunctional families who experienced more pain reported more distress, presumably because they did not receive adequate help and support from these families. This study underlines the importance of a broader perspective on family dynamics in coping with pain.

BACKGROUND: There is controversy about the efficacy of currently used treatment modalities to alleviate migraine headaches. OBJECTIVE: We aimed to evaluate and compare the effects of magnesium sulfate and combined use of dexamethasone/metoclopramide on relieving acute migraine headache. METHODS: We randomly divided 70 patients who had been referred to an emergency department, into two equal treatment groups with the two treatment plans, and analyzed pain severity at baseline using a numeric rating scale (NRS). We gave dexamethasone/metoclopramide to one group and magnesium sulfate to the other group, and evaluated pain severity at 20 min and at 1- and 2-h intervals after infusion. Finally, we used repeated-measure and two-way analysis of variance for intra- and inter-group evaluations of pain severity and complications, respectively. RESULTS: We found no significant differences in demographic data and pain severity at baseline (8.2 vs. 8.0) between the two groups (p < 0.05). In the dexamethasone/metoclopramide group, pain severity (mean ± standard deviation) was 7.4 ± 1.4 (p = 0.36), 6.0 ± 2.4, and 2.5 ± 2.9 (p < 0.0001) at 20-min, 1-h, and 2-h intervals after treatment, respectively, with statistically significant differences between the baseline values and 1-h and 2-h interval values. Administration of magnesium sulfate was associated with decreased pain severity at the three intervals (5.2 ± 1.7, 2.3 ± 1.9, and 1.3 ± 0.66, respectively), exhibiting significant differences compared to baseline values and the corresponding time intervals in the dexamethasone/metoclopramide group (p < 0.0001). CONCLUSIONS: According to the results, magnesium sulfate was a more effective and fast-acting medication compared to a combination of dexamethasone/metoclopramide for the treatment of acute migraine headaches.

BACKGROUND: Parkinson's disease (PD), the second most prevalent neurological disorder in the elderly, manifests with distinctive movement disorders, including bradykinesia, resting tremor, and stiffness. With a progressive course, current treatment strategies primarily target symptomatic relief. Crocin is a chemical compound isolated from the dry stigma of Crocus sativus, and has demonstrated neuroprotective properties. OBJECTIVES: This study explores the impact of crocin on movement disorders and neuronal oxidative DNA damage in PD patients. METHOD: Conducted as a randomized, blinded, and controlled trial, this research focused on patients aged 30 to 80 with idiopathic PD. Using the second and third parts of the movement disorder society-unified PD rating scale (MDS-UPDRS), aspects of daily life activity and movement disorders were assessed before and after an 8-week intervention. Patients in the crocin groups received capsules containing 30 mg of crocin twice daily. Additionally, the 8-hydroxy-2-deoxydiguanosine (8-OHdG) to urinary creatinine ratio (8-OHdG/uCr) was measured to evaluate neuronal oxidative DNA damage. RESULTS: Out of the initially evaluated 164 patients, 30 were randomly assigned to each group, with 53 subjects completing the study. Within-group analysis revealed a significant improvement in the second and third parts of MDS-UPDRS after 8 weeks of crocin intervention (P < 0.05). However, the 8-OHdG/uCr did not show significant changes. The well-tolerated daily dose of 60 mg of crocin demonstrated minimal side effects. CONCLUSION: This study establishes the efficacy of crocin in enhancing daily life activities and mitigating movement disorders, suggesting its potential as a supplementary intervention alongside conventional PD medications.
RESUMEN
To determine the effects of different prognostic factors, including previous antiplatelet therapy, admission data, and radiographic findings on discharge and 3-month neurological condition using modified Rankin scale (mRS) and mortality at 30 days and 3-month follow-up in patients presenting to the emergency department with spontaneous intracranial hemorrhage (sICH). Between January and July 2012, 120 consecutive patients (males 62%, females 38%), who were admitted within 48 h of symptoms onset, were included. We recorded the following data on admission: demographics; functional scores of ICH, Glasgow Coma Scale, and National Institutes of Health Stroke Scale; vital signs; smoking status; use of illicit drug; preadmission antiplatelet treatment; results of laboratory tests (platelet count, serum glucose, sodium and creatinine levels, and prothrombin time); and primary neuroimaging findings [intraventricular hemorrhage (IVH), midline shift, and hydrocephalus]. In multivariate analysis using adjusted model for demographics and prior antiplatelet therapy; functional scores, laboratory results, and diabetes history correlated with mortality during 30 days after the event. Moreover, the parameters on the initial computed tomography scan significantly increased 30-day fatality rate and was correlated with increase in the discharge mRS score of survivors. The odds ratio (OR) and 95% confidence interval (CI) of early mortality associated with IVH presentation was 2.34 (CI 1.76-3.02, p = 0.003). The corresponding ORs in those with midline shift displacement and hydrocephalus were 2.18 (95% CI 2.08-3.80, p = 0.01) and 1.62 (95% CI 1.01-2.63, p = 0.02), respectively. In patients with ICH, prognostic factors, include various clinical parameters and paraclinical findings of admission time.

Objectives: The aim of this study was to evaluate the effects of probiotics on the treatment of constipation in patients with Parkinson's disease (PD) by analyzing data from published randomized clinical trials (RCTs). PD is a neurodegenerative disease characterized by clinical symptoms such as rigidity, bradykinesia, and resting tremor. Constipation is a common complaint reported by PD patients. Probiotics are often used to treat functional constipation. The potential mechanisms behind PD-related constipation include dysfunction of the enteric nervous system due to alpha-synuclein aggregation, dyssynergic contractions of the puborectalis muscle, and alterations of the gut microbiome. Method: To conduct this study, we searched Scopus, PubMed, and Google Scholar for published articles on PD, probiotics, and constipation. We selected RCTs from 944 studies, and ultimately included 3 RCTs in our meta-analysis. The frequency of bowel movements per week was the only index that could be summarized among the records. We extracted and analyzed the results as means and standard deviations. Result: We calculated a standardized mean difference (SMD) of 0.92 (95% CI, 0.65 to 1.19; I-squared = 57.0%; p < 0.001) to determine the treatment effect in terms of frequency of bowel movements per week in the RCTs. Conclusion: Our results show that probiotic intake has beneficial effects on constipation in PD patients. Further research, including multicenter studies, is needed to assess the long-term efficacy and safety of probiotic supplements in neurodegenerative diseases.
RESUMEN
Background: Parkinson's disease (PD) is one of the common neurodegenerative diseases, and there has been an increasing interest in the potential role of intestinal dysbiosis in its pathogenesis and related gastrointestinal complications such as constipation. Objectives: This study aims to evaluate the effects of multi-strain probiotics on constipation and motor function in PD patients. Methods: This study was a blinded, randomized controlled trial (RCT) that involved 27 PD patients who were diagnosed with constipation according to the ROME IV criteria for functional constipation. The primary outcome measured before and after the intervention in both the placebo and probiotic groups was the frequency of defecation. Secondary outcomes evaluated were laxative use, sense of complete evacuation, Bristol Stool Scale for consistency, and Unified Parkinson's Disease Rating Scale (UPDRS) scale. The study lasted for eight weeks. Both groups also were educated about lifestyle modification. Results: Of 30 included patients (15 in each group), 13 were women, and 17 were men. Three patients dropped out of the study. Between-group analysis showed that the frequency of bowel movements significantly increased in the probiotic group 4 [3 - 5] in comparison with 2 [2 - 3] in placebo (P = 0.02). Stool consistency also improved in the probiotic group (P = 0.04). However, there were no significant differences in other outcomes. The within-group analysis showed improvement in stool consistency in both probiotics and placebo groups (P = 0.01 and P = 0.007, respectively), while stool frequency and sense of complete evacuation significantly improved only in the probiotic group (P < 0.05). Conclusions: This study demonstrated that multi-strain probiotics could improve frequency, consistency, and sense of complete evacuation in PD patients, while there was no significant effect on motor functions in 8 weeks. It is suggested that additional studies be conducted on longer-term effects.
RESUMEN
Thoracic outlet syndrome (TOS) is defined as compression of neurovascular components passing the thoracic outlet. While neurologic compression is the most common form, rare cases of arterial comprssion could result in concerning cerebral thromboembolic events. Here we present a 15-year-old female with repeated left hemiparesis and radiologic signs of cerebrovascular accident (CVA) in right middle cerebral artery. Further investigations revealed stenosis of the right subclavian artery, saccular aneurysm, and occlusion of the right brachial artery which suggested the diagnosis of arterial TOS. Based on this report, we present this diagnosis as a rare but important cause of CVA, especially in young patients.
RESUMEN
Stroke is one of the most common neurological disorders with a high incidence in Middle-eastern regions. We aimed to assess the diagnostic accuracy of neurovascular ultrasound to detect of cerebral artery stenosis compared to digital subtraction angiography (DSA) as a gold standard method. Eighty patients presenting with symptoms of cerebral ischemia were enrolled in the study. They were examined by cervical color Doppler ultrasound and TCCS to determine stenosis of extracranial and intracranial arteries, respectively. DSA was performed 24-48 h after the initial examination. The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of neurovascular ultrasound in comparison to DSA were calculated. The agreement between the two methods was determined by kappa statistics. Eighty patients (60% male, 40% female) with a mean age of 61.32 ± 12.6 years were included. In 65% of patients, stenosis in carotid artery caused ischemic symptoms. We did not observe any stenosis in anterior cerebral artery, posterior cerebral artery and basilar artery in patients. The agreement between the neurovascular ultrasound and DSA in various arterial vessels was 0.9 for common carotid artery, 0.86 for internal carotid artery, 0.78 for middle cerebral artery, and 0.86 for vertebral artery. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and kappa value of the neurovascular ultrasound for detecting stenosis regarding the arterial segments were 84.8%, 81%, 92.6%, 65.4%, 83.8, and 0.71, respectively. In conclusion, the neurovascular ultrasound is a valuable, non-invasive, and repeatable method to investigate cerebral artery stenosis with high diagnostic accuracy.

BACKGROUND: At the end of December 2019, a novel respiratory infection, initially reported in China, known as COVID-19 initially reported in China, and later known as COVID-19, led to a global pandemic. Despite many studies reporting respiratory infections as the primary manifestations of this illness, an increasing number of investigations have focused on the central nervous system (CNS) manifestations in COVID-19. In this study, we aimed to evaluate the CNS presentations in COVID-19 patients in an attempt to identify the common CNS features and provide a better overview to tackle this new pandemic. METHODS: In this systematic review and meta-analysis, we searched PubMed, Web of Science, Ovid, EMBASE, Scopus, and Google Scholar. Included studies were publications that reported the CNS features between 1 January 2020 and 20 April 2020. The data of selected studies were screened and extracted independently by four reviewers. Extracted data analyzed by using STATA statistical software. The study protocol registered with PROSPERO (CRD42020184456). RESULTS: Of 2,353 retrieved studies, we selected 64 studies with 11,687 patients after screening. Most of the studies were conducted in China (58 studies). The most common CNS symptom of COVID-19 was headache (8.69%, 95%CI: 6.76%-10.82%), dizziness (5.94%, 95%CI: 3.66%-8.22%), and impaired consciousness (1.90%, 95%CI: 1.0%-2.79%). CONCLUSIONS: The growing number of studies has reported COVID-19, CNS presentations as remarkable manifestations that happen. Hence, understanding the CNS characteristics of COVID-19 can help us for better diagnosis and ultimately prevention of worse outcomes.

BACKGROUND: Mindfulness-based interventions have shown to be efficient in managing chronic pain. Cognitive factors play a prominent role in chronic pain complications and negative cognitive contents about pain are often the first issues targeted in cognitive-based therapies, which are known as first-line treatment of chronic pain over the past decades. Little, however, is known about the manner of thinking about pain or pain-related cognitive processing. OBJECTIVES: Therefore, the purpose of this study was to investigate the effect of mindfulness-based cognitive therapy (MBCT) on pain-related cognitive processing and control of chronic pain in patients with primary headache. METHODS: A clinical trial was conducted in 2017 - 2018 on 85 Persian language patients with one type of primary headache selected through purposive sampling in Emam Hossein Hospital in Tehran province. To measure the variables of the study, we used the Brief Pain Inventory (BPI) and Pain-related Cognitive Processing Questionnaire (PCPQ). All data were analyzed by independent t-test and chi-square and longitudinal data were analyzed using linear mixed model analysis. RESULTS: Statistically significant time × group interactions were found in pain intensity (P < 0.001), pain interference (P < 0.001), as well as in three cognitive processing subscales including pain focus, pain distancing, and pain openness (P < 0.001). However, the results of pain diversion were not meaningful. CONCLUSIONS: MBCT is a potentially efficacious approach for individuals with headache pain. Regulation and correction of cognitive processing are considered as effective cognitive coping strategies in MBCT treatment.
RESUMEN
BACKGROUND: Primary headaches are one of the most troubled chronic diseases. Headaches interfere within the various dimensions of the patient's life. Coping strategies that aim to be attention focused (e.g., mindfulness) may moderate pain-related emotional and physical interference. OBJECTIVES: This investigation examined the relationship between mindfulness and pain intensity with physical and emotional interference and the subsequent aim was to analyze the role of mindfulness and headache severity combination in the prediction of pain-related interference. METHODS: This correlational study was conducted during years 2017 to 2018 at Imam Hossein Hospital of Tehran province. Eighty-five patients (56 females and 29 males), who had one type of primary headache were selected through purposive sampling after the diagnosis by a neurologist. The data were collected through the brief pain inventory (BPI) and the mindful attention awareness scale (MAAS). All data were analyzed using descriptive statistics. Bivariate correlation matrix and hierarchical stepwise linear regression statistics were used. RESULTS: The correlational analysis of the results indicated significant association between mindfulness (MAAS) and pain severity (BPI) (P < 0.01) as well as the findings of the study point to the significant relationship between mindfulness and both physical and emotional pain-related interference (P < 0.01). The results of stepwise linear regression indicated that pain severity explains only 1% of the total score in emotional pain-related interference (P = 0.003 and ΔF (1 and 83) = 9.22, ΔR2 = 0.11). Adding mindfulness to the model led to a 43% increase of the explained variance (R2 Change = 0.34). In physical interference, although pain severity was able to predict pain interference (P = 0.01 and ΔF (1 and 83) = 7.09, ΔR2 = 0.07), a combination model justifies 10% of the interference variance that was not statistically meaningful (P = 0.08, ΔR2 = 0.103). CONCLUSIONS: This result is a further support that Mindful Awareness contributed to emotional pain-related interference prediction. This result can explain the role of attention focused and mindful awareness in primary headache pain adjustment.
RESUMEN
BACKGROUND: Migraine is a common disease with neurovascular nature, which is commonly prevalent in the general population. Due to the significant prevalence of migraine and its long-term complications, it is necessary to pay attention to its exacerbating factors. Therefore, the aim of this study was to evaluate the frequency distribution of dyslipidemia in patients with migraine compared with control group. MATERIALS AND METHODS: This is a case-control study, in which 50 patients with migraine (with aura and without aura) were confirmed by the criteria of International Headache Society. Migraineurs and control group (n = 50) were selected from among patients who referred to the Neurology Clinic of Imam Hossein Hospital. The levels of total cholesterol, triglyceride, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol were measured in both the groups. SPSS software (version 21) was used to analyze the data. RESULTS: The findings showed that among migraineurs, 21 patients (42%) revealed high levels of cholesterol and 22 revealed high levels of LDL (44%); whereas among subjects without migraine, 12 subjects (24%) exhibited high levels of cholesterol and 12 (24%) high levels of LDL, where a significant correlation between the two groups was achieved. CONCLUSION: The present results showed that migraine is associated with higher level of cholesterol and LDL when compared with the control group, where a significant relationship was found.
RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: Crocus sativus L. has been used throughout the world in traditional medicine as a treatment for neurological disorders such as depression. Growing attention is currently being paid to the use of neuroprotective agents in ischemic strokes. AIM OF THE STUDY: This study assed the effect of saffron as a neuroprotective natural product in cerebral ischemia in human. STUDY DESIGN: Patients with acute ischemic stroke were randomly allocated to receive either routine stroke care (control group, nâ¯=â¯20) or routine care plus aqueous extract of saffron capsule (200â¯mg/day) (saffron-treated group, nâ¯=â¯19). Both groups were monitored during their four-day hospital stay and the three-month follow-up period. The groups were compared in terms of short- and long-term effects of saffron capsules using the National Institute of Health Stoke Scale (NIHSS), Barthel Scale, and serum neuron specific enolase (NSE), Brain-derived neurotrophic factor (BDNF), S100 levels. RESULTS: Based on the NIHSS, the severity of stroke during the first four days was significantly lower in the saffron-treated group than in the control group (Pâ¯<â¯0.05). Compared to the levels on the first day, serum NSE and s100 levels were significantly decreased and BDNF concentration was increased in the saffron-treated group on the fourth day. Also, our results showed there was a negative significant non-linear cubic regression between BDNF concentration and score of NIHSS. At the end of the three-month follow-up period, the mean Barthel index was significantly higher in the saffron-treated group than in the control group (Pâ¯<â¯0.001). CONCLUSION: The results of this study confirmed the short and long-term neuroprotective effects of aqueous extract of saffron on ischemic stroke in humans.

BACKGROUND: Primary headaches are the most common cause of absence from work and school and one of the most common reasons for referring to the neurologists. OBJECTIVES: The present study was designed to investigate the relationship of cognitive processing style and mindfulness with pain intensity and the ultimate aim was to provide the role of pain-related cognitive processes and mindfulness in the prediction of headache intensity. METHODS: The study was conducted descriptively by using the correlation method. The statistical population of this study was composed of 85 patients (56 females and 29 males) with one type of primary headache, which were selected through purposive sampling after the diagnosis of a headache by a neurologist at Imam Hossein Hospital in Tehran province. To measure the variables of the study, the numeric pain rating scale (NRS) and the pain-related cognitive processes questionnaire (PCPQ) were used. All data were analyzed using descriptive statistics (frequency and percentages). Bivariate correlation matrix and hierarchical stepwise linear regression statistics were used. RESULTS: The results showed that there was a significant and negative association between pain intensity (NRS) and mindfulness (P < 0.01) and all pain-related cognitive processes, except pain focus (P < 0.01). The results of stepwise linear regression indicated that mindfulness only explains 39% of total score changes in pain intensity (P < 0.05 and ΔF (1 and 83) = 53.63, ΔR = 0.385). Adding cognitive processing styles to the model led to an 18% increase of the explained variance (R2 change = 0.179). In total, the present research model justifies 54% of the severity of headache variance (P < 0.01, ΔR = 0.54). CONCLUSIONS: The results suggest that pain-related cognitive processes and mindfulness are effective on pain intensity prediction. In other words, this result can explain the role of mindfulness and adaptive cognitive processing in primary headache pain management.
