RESUMO

BACKGROUND: Fampridine is a potassium channel blocker drug used to improve walking ability in patients with multiple sclerosis (MS). We evaluated the effect of fampridine in patients with MS in the acute phase of transverse myelitis. METHODS: In a randomized, placebo-controlled trial, 30 patients who had their first episode of cervical myelitis with quadriparesis presentation, with the final diagnosis of MS, were randomly divided into two equal groups. The intervention group received intravenous methylprednisolone (IVMP) for 7 days plus fampridine. The placebo group received IVMP for 7 days plus placebo. To compare the treatment results, we compared the Barthel index (BI) scores of the groups at the start of the trial and the 21st day after the start of treatment. RESULTS: There was no significant difference in baseline characteristics between the intervention and placebo groups in terms of mean age, sex, and mean admission BI (p > 0.05). Mean (SD) admission BI in placebo and intervention groups was 27.20 (7.341) and 27.87(5.78), respectively (p = 0.784). The measured mean (SD) BI after treatment was 48.73 (15.54) in the placebo and 64.93 (11.81) in the intervention group (p = 0.003) after 3 weeks. CONCLUSION: Using fampridine plus IVMP in the acute phase of transverse myelitis in MS patients improved the disease's symptoms and increased the daily activity ability of patients.

RESUMO

Diabetes mellitus may cause tau protein hyperphosphorylation and neurodegeneration, but the exact mechanism by which diabetic conditions induce tau pathology remains unclear. Tau protein hyperphosphorylation is considered a major pathological hallmark of neurodegeneration and can be triggered by diabetes. Various tau-directed kinases, including P38, can be activated upon diabetic stress and induce tau hyperphosphorylation. Despite extensive research efforts, the exact tau specie(s) and kinases driving neurodegeneration in diabetes mellitus have not been clearly elucidated. We herein employed different techniques to determine the exact molecular mechanism of tau pathology triggered by diabetes in in vivo and in vitro models. We showed that diabetes-related stresses and glucose metabolism deficiency could induce cis P-tau (an early driver of the tau pathology) accumulation in the midbrain and corpus callosum of the diabetic mice models and cells treated with 2-deoxy-D-glucose, respectively. We found that the active phosphorylated level of P38 was increased in the treated cells and diabetic mice models. We observed that oxidative stress activated P38, which directly and indirectly drove tau pathology in the GABAergic and glutamatergic neurons of the midbrain of the diabetic mice after 96 h, which accumulated in the other neighboring brain areas after 2 months. Notably, P38 inhibition suppressed tau pathogenicity and risk-taking behaviors in the animal models after 96 h. The data establish P38 as a central mediator of diabetes mellitus-induced tau pathology. Our findings provide mechanistic insight into the consequences of this metabolic disorder on the nervous system.

RESUMO

Tau protein abnormalities are associated with various neurodegenerative disorders, including Alzheimer's disease (AD) and traumatic brain injury (TBI). In tau-overexpressing SHSY5Y cells and iPSC-derived neuron models of frontotemporal dementia (FTD), axonal tau translocates into the nuclear compartment, resulting in neuronal dysfunction. Despite extensive research, the mechanisms by which tau translocation results in neurodegeneration remain elusive thus far. We studied the nuclear displacement of different P-tau species [Cis phosphorylated Thr231-tau (cis P-tau), phosphorylated Ser202/Thr205-tau (AT8 P-tau), and phosphorylated Thr212/Ser214-tau (AT100 P-tau)] at various time points using starvation in primary cortical neurons and single severe TBI (ssTBI) in male mouse cerebral cortices as tauopathy models. While all P-tau species translocated into the somatodendritic compartment in response to stress, cis P-tau did so more rapidly than the other species. Notably, nuclear localization of P-tau was associated with p53 apoptotic stabilization and nucleolar stress, both of which resulted in neurodegeneration. In summary, our findings indicate that P-tau nuclear translocation results in p53-dependent apoptosis and nucleolar dispersion, which is consistent with neurodegeneration.

RESUMO

BACKGROUND: Growing bodies of evidence suggest that angiogenesis plays a crucial role in the development and progression of multiple sclerosis (MS). Vascular endothelial growth factor (VEGF) is one of the key factors involved in angiogenesis. Because of this importance, we investigated the serum levels of VEGF in MS patients according to their clinical phase and subtype of MS in this study. MATERIAL AND METHODS: This case-control study was done on 47 definite MS patients with the first clinical attack and 47 randomly selected individuals without any underlying inflammatory and autoimmune disease as the control group. The total serum VEGF level was measured from the subject's peripheral blood sample by ELISA during the first and second attacks of MS and 6 months after the first attack in the remission phase as well as the control group. In addition, the correlation between these variables and the influence of gender, age, and duration of the remission phase on such associations was evaluated by using the independent t test and Pearson's correlation coefficient. RESULTS: There was an increase in the serum level of VEGF in all phases of MS compared with non-MS individuals (p value <0.0001) and a significant correlation between the serum level of VEGF and the interval between first and second attacks (r = -720, p < 0.0001). A higher serum level of VEGF in the first attack leads to higher VEGF levels in the second and sixth mount of remission phases. CONCLUSION: Rise in the serum VEGF level may be involved in MS's relapsing phases and a shorter remission phase. Therefore, it could be used as a prognostic and predictive biomarker for MS disease.

RESUMO

During the COVID-19 pandemic, methanol-containing beverages' consumption has risen because people mistakenly believed that alcohol might protect them against the virus. This study aimed to evaluate the prevalence and predisposing factors of brain lesions in patients with methanol toxicity and its outcome. A total of 516 patients with confirmed methanol poisoning were enrolled in this retrospective study, of which 40 patients underwent spiral brain computed tomography (CT) scan. The presence of unilateral or bilateral brain necrosis was significantly higher in the non-survival group (p = 0.001). Also, intracerebral hemorrhage (ICH) and brain edema were prevalent among patients that subsequently died (p = 0.004 and p = 0.002, respectively). Lower Glasgow Coma Scale (GCS) was related to a higher mortality rate (p = 0.001). The mortality rate in chronic alcohol consumption was lower than the patients who drank alcohol for the first time (p = 0.014). In conclusion, increasing the number of methanol poisoning and its associated mortality and morbidity should be considered a threat during the COVID-19 pandemic.

RESUMO

As the SARS-COV-2 becomes a global pandemic, many researchers have a concern about the long COVID-19 complications. Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a persistent, debilitating, and unexplained fatigue disorder. We investigated psychological morbidities such as CFS and post-traumatic stress disorder (PTSD) among survivors of COVID-19 over 6 months. All COVID-19 survivors from the university-affiliated hospital of Tehran, Iran, were assessed 6 months after infection onset by a previously validated questionnaire based on the Fukuda guidelines for CFS/EM and DSM-5 Checklist for PTSD (The Post-traumatic Stress Disorder Checklist for DSM-5 or PCL-5) to determine the presence of stress disorder and chronic fatigue problems. A total of 120 patients were enrolled. The prevalence rate of fatigue symptoms was 17.5%. Twelve (10%) screened positive for chronic idiopathic fatigue (CIF), 6 (5%) for CFS-like with insufficient fatigue syndrome (CFSWIFS), and 3 (2.5%) for CFS. The mean total scores in PCL-5 were 9.27 ± 10.76 (range:0-44), and the prevalence rate of PTSD was 5.8%. There was no significant association after adjusting between CFS and PTSD, gender, comorbidities, and chloroquine phosphate administration. The obtained data revealed the prevalence of CFS among patients with COVID-19, which is almost similar to CFS prevalence in the general population. Moreover, PTSD in patients with COVID-19 is not associated with the increased risk of CFS. Our study suggested that medical institutions should pay attention to the psychological consequences of the COVID-19 outbreak.

RESUMO

Alzheimer's disease (AD) is a neurodegenerative disorder, in which amyloid precursor protein (APP) misprocessing and tau protein hyperphosphorylation are well-established pathogenic cascades. Despite extensive considerations, the central mediator of neuronal cell death upon AD remains under debate. Therefore, we examined the direct interplay between tauopathy and amyloidopathy processes. We employed primary culture neurons and examined pathogenic P-tau and Aß oligomers upon hypoxia treatment by immunofluorescence and immunoblotting. We observed both tauopathy and amyloidopathy processes upon the hypoxia condition. We also applied Aß1-42 or P-tau onto primary cultured neurons. We overexpressed P-tau in SH-SY5Y cells and found Aß accumulation. Furthermore, adult male rats received Aß1-42 or pathogenic P-tau in the dorsal hippocampus and were examined for 8 weeks. Learning and memory performance, as well as anxiety behaviors, were assessed by Morris water maze and elevated plus-maze tests. Both Aß1-42 and pathogenic P-tau significantly induced learning and memory deficits and enhanced anxiety behavior after treatment 2 weeks. Aß administration induced robust tauopathy distribution in the cortex, striatum, and corpus callosum as well as CA1. On the other hand, P-tau treatment developed Aß oligomers in the cortex and CA1 only. Our findings indicate that Aß1-42 and pathogenic P-tau may induce each other and cause almost identical neurotoxicity in a time-dependent manner, while tauopathy seems to be more distributable than amyloidopathy.

RESUMO

This study aimed to evaluate the attention and inhibitory control functions in patients with genetic generalized epilepsy (GGE) and psychogenic nonepileptic seizure (PNES) and compare the results with the healthy control subjects. A total of 30 patients with GGE, 30 patients with PNES, and 32 healthy control subjects were included in the study. The severity of attention and inhibitory control deficit, general intelligence status, and psychopathology screening in all subjects were respectively investigated with the Integrated Visual and Auditory Continuous Performance Test (IVA-CPT), the Wechsler Adult Intelligence Scale (WAIS), and the Symptoms Checklist 90-revised (SCL-90-R). Patients with PNES had severe impairments in all performed tasks compared with the control group and the group with GGE (p < 0.01), whereas patients with GGE had significantly lower attention quotient versus healthy subjects (p < 0.01). The full-scale attention quotient (FSAQ) and full-scale response control quotient (FSRCQ) in patients with PNES were significantly lower in comparison with GGE (47.83 ±â€¯32.68, 60.18 ±â€¯35.35, p < 0.01), respectively. Multiple regression analysis did not demonstrate any significant effect of seizure frequency or epilepsy duration on attention and inhibitory control deficits, but patient's intelligence quotient (IQ) showed a significant effect on FSAQ and FSRCQ (ß: 0.997, p < 0.001; ß: 0.933, p < 0.001, respectively). Attention and inhibitory control are significantly impaired in patients with GGE and PNES. The cognitive deficits in patients with GGE and PNES have potentially important clinical implications in planning their neuropsychological rehabilitation.

RESUMO

Alzheimer's disease (AD) is the sixth leading cause of death globally and the main reason for dementia in elderly people. AD is a long-term and progressive neurodegenerative disorder that steadily worsens memory and communicating skills eventually leads to a disabled person of performing simple daily tasks. Unfortunately, numerous clinical trials exploring new therapeutic drugs have encountered disappointing outcomes in terms of improved cognitive performance since they are not capable of halting or stimulating the regeneration of already-damaged neural cells, and merely provide symptomatic relief. Therefore, a deeper understanding of the mechanism of action of stem cell may contribute to the development of novel and effective therapies. The revolutionary discovery of stem cells has cast a new hope for the development of disease-modifying treatments for AD, in terms of their potency in the replenishment of lost cells via differentiating towards specific lineages, stimulating in situ neurogenesis, and delivering the therapeutic agents to the brain. Herein, firstly, we explore the pathophysiology of AD. Next, we summarize the most recent preclinical stem cell reports designed for AD treatment, their benefits and outcomes according to cell type. We briefly review relevant clinical trials and their potential clinical applications in order to find a unique solution to effectively relieve the patients' pain.

RESUMO

BACKGROUND AND AIM: Interferon beta is currently the first line treatment of relapsing-remitting multiple sclerosis (RRMS). Different formulations of interferon beta are available. Avonex and CinnoVex are two interferon beta-1a being prescribed by neurologists in Iran. The aim of this study was to compare the four and half year outcome of Avonex and CinnoVex in patients with RRMS. METHODS: A total 186 of patients with definite RRMS diagnosis were followed for four and half years. Patients were randomly assigned to receive either Avonex or CinnoVex. Patients were subsequently visited every 6 months, and MRI was also undertaken prior each visit. The efficacy end points were to compare mean scores of expanded disability status scale (EDSS) and the proportion of patients with MRI and clinical activity in follow-up visits between Avonex and CinnoVex. Safety end point was to compare the percentage of adverse events between two groups. RESULTS: One hundred and eighty-two patients completed the study. The population of study experienced a steady increase in EDSS during follow-up with a mean increase of 1.03. Repeated measures ANOVA revealed no statistically significant difference between Avonex and CinnoVex (p = 0.78). The most common adverse events were headache, myalgia, fatigue, fever, flu symptoms, injection site pain, and depression. Direct comparison of each adverse events revealed no meaningful difference between two groups except for only a few adverse events. There was no statistically significant difference in MRI activity and clinical activity between two groups. CONCLUSION: Avonex and CinnoVex showed similar efficacy and safety outcome in patients with RRMS.

RESUMO

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.

RESUMO

Drug-resistant epilepsy seems like a different disease compared with easy to control epilepsy, and new strategies are needed to help these patients. Vagus nerve stimulation (VNS) therapy is the most frequently used neurostimulation modality for patients with drug-resistant epilepsy who are not eligible for seizure surgery. In this study, we aimed to evaluate the efficacy and adverse effects of VNS in patients with drug-resistant epilepsy in an open-label, prospective, long-term study in Iran. We selected 48 patients with partial-onset drug-resistant epilepsy. Implantations were performed in the neurosurgery department of Loghman Hospital, Tehran, Iran. Follow-up visits were done on monthly bases for 5 years. Forty-four patients completed the study. Mean age of patients was 24.4 years. Mean years of epilepsy history was 14 years. The mean number of anti-epileptic drugs did not significantly change over five years (p = 0.15). There was no exacerbation of epilepsy; however, one patient discontinued his therapy due to unsatisfactory results. Five patient had more than 50 %, and 26 patients (59 %) had 25-49 % reduction in the frequency of monthly seizures persistently. Overall mean frequency of monthly seizures decreased by 57.8, 59.6, 65, 65.9, and 67 %, in 1st, 2nd, 3rd, 4th, and 5th years of follow-up, respectively. Most common side effects were as follows: hoarseness (25 %) and throat discomfort (10 %). We found VNS as a safe and effective therapy for drug-resistant epilepsy, with an approximate long-term decrease in mean seizure frequency of 57.8-67 %. Thus, VNS is recommended for suitable patients in developing countries.

RESUMO

BACKGROUND: Magnetic resonance imaging (MRI) has improved the diagnosis and management of patients with multiple sclerosis (MS). Montreal Cognitive Assessment (MoCA) is a brief, sensitive test that has been recommended by National Institute of Neurological Diseases and Stroke and Canadian Stroke Network (NINDS-CSN) as a reliable tool to detect mild cognitive impairments. This study aimed to evaluate the relationship between MoCA test and its sub-items with brain abnormalities in MRI of MS patients. METHODS: Based on MRI scans of 46 MS patients, third ventricle and white matter lesions volumes were measured. Disease duration and expanded disability status scale (EDSS) were recorded in each patient. In addition, cognitive domains of the patients were evaluated by Montreal cognitive assessment (MoCA) test. We analyzed data using t-test or Mann-Whitney U test, Pearson correlation coefficient, and non-parametric Spearman test. Furthermore, multiple linear regression model was applied to evaluate the association between cognitive indices and MRI characteristics. RESULTS: Among MRI indices, only severity of atrophy showed a significant difference between cognitively impaired and cognitively preserved patients. Third ventricular volume was significantly correlated with total MoCA score (p=0.003, r=-0.42), but none of the juxtacortical or periventricular lesions volume revealed significant relation with total MoCA score. However, using multivariate linear regression after adjustment for educational level and disease duration, there was a significant negative association between juxtacortical lesions volume and total MoCA score as well as naming and attention sub-items. Also, memory score was adversely associated with the third ventricular volume (p=0.03, r=0.31). CONCLUSION: Cognitive disturbances detected by MoCA, may be associated with some pathological changes including atrophy, third ventricular volume, and juxtacortical lesion. MoCA, as a brief test, is not correlated with brain lesions volume in MS patients.

RESUMO

We have reviewed the clinical literature with reference to the local applicability of guidelines for the diagnosis and management of multiple sclerosis (MS) in the Middle East. There is a substantial burden of MS in the region: the prevalence of the disease appears to have increased markedly in recent decades, with a faster rate of increase in female vs. male patients. The aetiology and presentation of MS appears to be broadly similar in the Middle East to that in other regions. Interferon-ß is the most commonly used treatment for MS in the Middle East, as elsewhere, although it is unclear to what extent economic constraints act as a barrier to accessing this treatment. Similarly, limited available data suggest that the availability of MRI scanners appears to be lower in the Middle East than in more developed nations. Little is known concerning other potential barriers to treatment. There is a need for further research on aspects of management of MS beyond the pharmacological aspects of treatment to assess fully the potential barriers to the adoption of international guidelines for the diagnosis and management of the disease in the Middle East.

RESUMO

Many COVID-19 survivors experience lingering post-COVID-19 symptoms, notably chronic fatigue persisting for months after the acute phase. Despite its prevalence, limited research has explored effective treatments for post-COVID-19 fatigue. This randomized controlled clinical trial assessed the impact of Amantadine on patients with post-COVID-19 fatigue. The intervention group received Amantadine for two weeks, while the control group received no treatment. Fatigue levels were assessed using the Visual Analog Fatigue Scale (VAFS) and Fatigue Severity Scale (FSS) questionnaires before and after the trial. At the study's onset, VAFS mean scores were 7.90 ± 0.60 in the intervention group and 7.34 ± 0.58 in the control group (P-value = 0.087). After two weeks, intervention group scores dropped to 3.37 ± 0.44, significantly lower than the control group's 5.97 ± 0.29 (P-value < 0.001). Similarly, FSS mean scores at the trial's commencement were 53.10 ± 5.96 in the intervention group and 50.38 ± 4.88 in the control group (P-value = 0.053). At the trial's end, intervention group scores decreased to 28.40 ± 2.42, markedly lower than the control group's 42.59 ± 1.50 (P-value < 0.001). In this study, we report the safety, tolerability, and substantial fatigue-relieving effects of Amantadine in post-COVID-19 fatigue. The intervention demonstrates a statistically significant reduction in fatigue levels, suggesting Amantadine's potential as an effective treatment for this persistent condition.

RESUMO

Many population-based studies have been performed to determine the prevalence of different types of headaches; however, none of them was performed in Tehran urban area as a huge and crowded metropolitan with multiple serious problematic crises. This study was performed to evaluate the prevalence rates of different types of headache among adult population of Tehran urban area in the year 2010. In this cross-sectional survey, a "face-to-face, in-door" structured interview was developed and used in district 8 of Tehran urban area as one representative region in the year 2010. A form concerning the prevalence of different types of headaches which also comprised the characteristics of the headaches and sociodemographic data was designed. After enrollment, participation rate of 91% (3,655 out of 4,000) was achieved. Of 3,655 recruited individuals, 2,778 (76%) people have experienced headache within last year. Tension-type headache and migraine were the most common types with the prevalence of 48.6% (n = 1,777) and 18.2% (n = 665), while, chronic daily, medication overuse headache and cluster headaches were presented in 7.0% (n = 255), 4.9% (n = 180) and 0.1% (n = 3), respectively. The prevalence of primary headaches in a sample of Tehran adult population is considerable. This high prevalence of headaches necessitates further evaluation of possible risk factors derived from leaving in such a crowded metropolitan area.

RESUMO

Soft tissue filler injection is the second most common nonsurgical cosmetic procedure. Despite the safety of fillers, as use has grown, so has the number of patients affected by adverse events. Ophthalmoplegia following cosmetic filler injection is a rare complication, mostly occurring after injection to the glabella, nasolabial fold, periorbital, and lateral nasal site. In all cases where ophthalmoplegia has been reported following fillers, patients have simultaneously experienced vision loss and other ocular symptoms. We report a case of isolated acute ophthalmoplegia following hyaluronic acid injection solely in the temple region. A 40-year-old woman, 3 hours after the procedure, presented to our hospital with left eye ophthalmoplegia, ptosis, and hypotropia. Treatment started with hyaluronidase, steroids, and anticoagulants. After 4 weeks, left eye ophthalmoplegia remained unchanged, and through a 10-week follow-up, all left ocular movements improved, and only mild hypotropia and ptosis persisted. This case report shows that ophthalmoplegia may also happen with temple region filler injections. We also review available prevention techniques and treatments to avoid such complications when performing soft tissue fillers for gaunt appearance correction.

RESUMO

BACKGROUND: MLC601 and MLC901 showed neuroprotective and neuroregenerative properties and positive results in the treatment of dementia and cognitive impairment. This study aimed to investigate the long-term benefits of monotherapy with MLC601 and MLC901 in patients with Alzheimer's disease (AD). METHODS: In this study, patients with AD, diagnosed by DSM-IV criteria, were enrolled. Patients have received MLC601 for four years, and their regimen has changed to MLC901 for another four years. Recruited patients were followed to assess the efficacy and safety first of MLC601 and MLC901. Mini-Mental State Examination (MMSE) and Alzheimer's Disease Assessment Scale- Cognitive Subscale (ADAS-Cog) were used to assess cognitive function. Safety was evaluated by monitoring adverse events (AEs) and abnormal findings in physical examinations or lab tests. RESULTS: At the end of the trial, the changes in the mean (±SD) MMSE and ADAS-Cog scores were 5.1 (3.09) and 12.5 (10.89), respectively. Both scores showed a significant change in repeated measure analysis, with the ADAS-Cog score indicating a higher change than the MMSE score (P < 0.001). CONCLUSION: For more than eight years, we studied monotherapy with NeuroAid (MLC601, MLC901) in patients with AD. The study contributes further to the long-term safety and efficacy data of MLC in patients with AD.

RESUMO

BACKGROUND: Hypoxic-ischemic brain injury (HIBI) is a disabling consequence of cardiopulmonary resuscitation, which has no direct treatment except supportive care. Many studies have used pharmacological agents to reduce or stop this disability. MLC901 is a traditional Chinese medicine showing neuroprotective and regenerative effects on focal and global ischemia in previous animal and human studies. We designed an experimental, randomized, double-blind, placebo-controlled study to analyze MLC901 efficacy in HIBI patients. METHODS: In a randomized, placebo-controlled trial, 35 patients with HIBI were randomly designated to receive either MLC901 or placebo capsules 3 times per day over 6 months. We assessed the 2 groups by modified Rankin Scale and Glasgow Outcome Scale at baseline, and follow-up visits in 3rd month, and 6th-month after injury. RESULTS: Thirty-one patients completed this study. There was no significant difference in baseline characteristics between the 2 groups as regards age, gender, time of resuscitation, the interval between injury and start of the intervention, and the length of intensive care unit stay. Both the placebo and intervention groups improved during the investigation. However, the Glasgow Outcome Scale and modified Rankin Scale scales were significantly improved in the MLC901 group compared to the placebo after 6 months (P < .05) with close to no adverse effects. No major side effect was reported. CONCLUSION: MLC901 has shown, compared to placebo, a statistically better improvement at 6 months in neurological functions of patients with HIBI.
