Article Synopsis
  • The study aimed to determine how motor signs in older adults with mild cognitive impairment (MCI) can predict the onset of dementia with Lewy bodies (DLB), especially focusing on differences between sexes.
  • Researchers analyzed data from individuals over 55 years old, assessing various motor signs like resting tremor and bradykinesia, and found that certain signs significantly increased the risk of developing DLB, particularly in women.
  • Results indicated that masked facies and resting tremor raised the risk of DLB considerably in women compared to men, while other motor signs like rigidity and hypophonia impacted the risk of different types of dementia, but not all motor features correlated with dementia risk.

Introduction: People with epilepsy (PWE) have been hypothesized to have higher prevalence of personality disorders and cognitive disorders. The objective of this study was to investigate the controversial notion of "epileptic personality," a series of supposedly specific personality traits of people with epilepsy (PWE).

Methods: For this purpose, 29 individuals with Mesial Temporal lobe Epilepsy (MTLE) and 23 with Juvenile myoclonic epilepsy (JME) as confirmed by electroencephalography (EEG), MRI scans and clinical examination, underwent a thorough neuropsychological and personality assessment.

Article Synopsis
  • - The study aimed to explore cognitive deficits during transient global amnesia (TGA) episodes, discovering that impairments extend beyond just episodic memory.
  • - Researchers reviewed 1302 articles, ultimately including 17 in their analysis, and found that TGA patients experience significant issues with spatiotemporal awareness, anterograde amnesia, and working memory during acute episodes.
  • - Although many cognitive functions remain normal, recovery typically starts with spatiotemporal orientation, followed by working and semantic memory retrieval, while episodic memory issues may last longer, with subtle memory deficits possible even after 24 hours.

Introduction/aims: Myotonia congenita (MC) is the most common hereditary channelopathy in humans. Characterized by muscle stiffness, MC may be transmitted as either an autosomal dominant (Thomsen) or a recessive (Becker) disorder. MC is caused by variants in the voltage-gated chloride channel 1 (CLCN1) gene, important for the normal repolarization of the muscle action potential.

In this narrative review, we delved into the intricate interplay between alleles (typically associated with Alzheimer's disease-AD) and alpha-synucleinopathies (aS-pathies), involving Parkinson's disease (PD), Parkinson's disease dementia (PDD), dementia with Lewy bodies (DLB), and multiple-system atrophy (MSA). First, in-vitro, animal, and human-based data on the exacerbating effect of on LB pathology were summarized. We found robust evidence that carriage constitutes a risk factor for PDD-APOE2, and APOE3 may not alter the risk of developing PDD.

Background: Rituximab, a B-cell depleting monoclonal antibody, represents an option for the treatment of refractory myasthenia gravis (MG). Its use is more established in muscle-specific tyrosine kinase positive (MuSK +) patients, while its role in managing acetylcholine receptor positive (AChR +), or double seronegative (DSN) patients, remains less clear. This study evaluates the long-term effectiveness and safety of rituximab in MG of various serotypes.

Background And Aims: Axonal forms of Charcot-Marie-Tooth disease (CMT) are classified as CMT2, distal hereditary motor neuropathy (dHMN) or hereditary sensory neuropathy (HSN) and can be caused by mutations in over 100 genes. We presently aimed to investigate for the first time the genetic landscape of axonal CMT in the Greek population.

Methods: Sixty index patients with CMT2, dHMN or HSN were screened by a combination of Sanger sequencing (GJB1) and next-generation sequencing custom-made gene panel covering 24 commonly mutated genes in axonal CMT.

Muscle-specific kinase (MuSK) Myasthenia Gravis (MG) represents a prototypical antibody-mediated disease characterized by predominantly focal muscle weakness (neck, facial, and bulbar muscles) and fatigability. The pathogenic antibodies mostly belong to the immunoglobulin subclass (Ig)G4, a feature which attributes them their specific properties and pathogenic profile. On the other hand, acetylcholine receptor (AChR) MG, the most prevalent form of MG, is characterized by immunoglobulin (Ig)G1 and IgG3 antibodies to the AChR.

Article Synopsis
  • The ADVANCE-CIDP 1 study tested the effectiveness and safety of facilitated subcutaneous immunoglobulin (fSCIG) in reducing relapses of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) compared to a placebo.
  • The study was a phase 3 trial that involved 132 eligible adults who had been receiving stable intravenous immunoglobulin (IVIG) prior to being randomized to either fSCIG or placebo for 6 months.
  • Results showed that fSCIG significantly reduced CIDP relapse rates compared to the placebo, although adverse events were more frequent with fSCIG, but serious complications were less common.

Functional dyspepsia is a gastrointestinal disorder characterized by postprandial fullness, early satiation, epigastric pain, and epigastric burning. The pathophysiology of the disease is not fully elucidated and there is no permanent cure, although some therapies (drugs or herbal remedies) try to reduce the symptoms. Diet plays a critical role in either the reduction or the exacerbation of functional dyspepsia symptoms; therefore dietary management is considered to be of high importance.
