(1) Background: Individuals with multiple sclerosis (MS) have to deal with numerous symptoms that adversely impact their quality of life. While pharmaceutical treatments offer some relief, they often fall short of addressing the full spectrum of MS symptoms. To bridge this gap, we introduce the Be Cool rehabilitation program, a comprehensive protocol designed to enhance the well-being and life quality of MS individuals.

Introduction: Fingolimod is the first approved oral therapy for relapsing-remitting multiple sclerosis (RRMS). The present study aimed to further characterize fingolimod's safety profile, and to assess the patient-reported treatment satisfaction and impact of fingolimod on the quality of life (QoL) of patients with multiple sclerosis (MS) treated in routine care in Greece.

Methods: This was a multicenter, prospective, observational, 24-month study conducted in Greece by hospital-based and private practice neurologists who specialize in MS.

IgG antibodies to myelin oligodendrocyte glycoprotein (MOG) detected by cell based assays (CBA) have been identified in a constantly expanding spectrum of CNS demyelinating disorders. However, a universally accepted CBA has not been adopted yet. We aimed to analyze the clinical and radiological features of patients with anti-MOG IgG1-antibodies detected with a live-cell CBA and to compare the three most popular MOG-CBAs.

Background: The management of "aggressive" and "highly-active" relapsing-remitting multiple sclerosis remains problematic. Although a number of highly efficacious agents are currently available, the optimal timing of their use and the balancing between efficacy and immediate and long-term consequences are still a matter of conjecture.

Methods: We describe the clinical, radiological and immunological profile of three multiple sclerosis patients with persistent clinical and radiological disease activity under fingolimod treatment.

Background: Cognitive impairment (CI) is detected in 40-70% of multiple sclerosis (MS) patients, but only 33-50% of the CI variance is explained by the disease burden assessed by MRI. The cognitive reserve (CR) hypothesis has been postulated to account for this discrepancy. So far, most previous studies have confirmed the CR hypothesis in MS but failed to examine CR indices collectively or use clinically relevant neuropsychological assessments.

The art of the confined began to be studied by psychiatrists in the late 19th century for diagnostic purposes, while the first studies of aesthetic interest were found in the first decades of the 20th century, when psychiatrists as the Swiss W. Morgenthaler and the Austrian H. Prinzhorn published studies on mentally ill artworks, having mainly aesthetic approach.

The thalassemias are the most common single gene disorder in the world. Nowadays, the average life expectancy of patients in developed countries has increased significantly, while, there was an increase of complications. We aimed to investigate peripheral neuropathy and myopathy in this patient group using a neurophysiological study.

An ongoing debate on decision and cost-utility analyses is whether to use preferences of general public or patients. The aim of this study was to replicate the valuation procedure of the multi-attribute utility generic measure, 15D, using a sample of multiple sclerosis (MS) patients and to assess its psychometric properties. Consecutive outpatient MS patients were recruited from two MS centers in Greece.

Background: Cerebral thromboembolism is a rare, but well-recognized complication of angiographic procedures. Peduncular hallucinosis (PH) is a form of complex visual hallucinations usually associated with lesions in the midbrain and thalamus.

Case Presentation: We report the case of a 79-years-old male patient with internuclear ophthalmoplegia and vivid lilliputian visual hallucinations (peduncular hallucinations), caused by a pontine infarction following coronary artery catheterization.

Background: The purpose of this study was to investigate with neurophysiological and neuropsychological methods such as pupillometry, cognitive test and Hamilton Depression Rating Scale (HAM-D) the hypothesis of Central Nervous System (CNS) cholinergic involvement in patients with Myasthenia Gravis (MG).

Methods: Thirty-two patients (32) with MG and a mean age of 51.1 ± 17.

The thalassemias are the most common single gene disorder in the world. Over the last years, several reports have demonstrated neurological complications in beta-thalassemia patients. In most cases, these complications remained subclinical and were detected only during neuropsychological, neurophysiological, or neuroimaging evaluation.

Article Synopsis
  • * A study identified 20 MS registries, with 13 completing a questionnaire and 7 participating in interviews, revealing significant variations in their goals and data collection.
  • * Common research aims included epidemiology and therapy outcomes, but only a few registries gathered data from patients' perspectives, highlighting the need for better integration of this information across Europe.

Objective: A behavioural study was conducted to investigate how cerebellar dysfunction associated with multiple sclerosis affects the ability to learn a novel visuo-postural co-ordination task.

Design: A prospective design, 2 group by 1 treatment (4 practice blocks).

Subjects: Ten patients with multiple sclerosis diagnosed with cerebellar ataxia and 10 age-matched healthy controls.

Multiple sclerosis (MS) is an autoimmune disorder of myelin destruction. Blood-brain-barrier (BBB) disruption precedes pathological or clinical findings and could involve mediators from perivascular brain mast cells, such as histamine and vascular endothelial growth factor (VEGF). Mast cells could be activated by many triggers, including acute stress that has been correlated with MS exacerbations.

Article Synopsis
  • Experimental allergic encephalomyelitis (EAE) serves as a key animal model for studying multiple sclerosis (MS), helping researchers understand the disease's inflammatory attacks on the central nervous system and myelin sheath.
  • Insights gained from EAE studies have identified various myelin antigens targeted by the immune system and have informed the use of immunomodulating therapies for MS.
  • While altered peptide ligands (APL) show promise in treating EAE and potentially MS, challenges like peptide sensitivity to enzymes and side effects exist, necessitating further research and clinical trials to assess their effectiveness.

Recent clinical studies in multiple sclerosis (MS) provide new data on the treatment of clinically isolated syndromes, on secondary progression, on direct comparison of immunomodulatory treatments and on dosing issues. All these studies have important implications for the optimized care of MS patients. The multiple sclerosis therapy consensus group (MSTCG) critically evaluated the available data and provides recommendations for the application of immunoprophylactic therapies.

Mitochondrial monoamine oxidase (MAO), type B, has been implicated in the etiology of schizophrenia. We have found the phospholipid, phosphatidylserine (PS) to be a highly specific inhibitor of MAO-B, which has led us to postulate that the PS-MAO interaction might offer a basis for the lower MAO levels observed in platelets from certain schizophrenic populations. In this study we compared platelet MAO activity with phospholipid composition in a group of normals and chronic paranoid schizophrenics.
