Background: Patients with multiple sclerosis (MS) experience difficulties in understanding speech in noise despite having normal hearing.

Aim: This study aimed to determine the relationship between speech discrimination in noise (SDN) and medial olivocochlear reflex levels and to compare MS patients with a control group.

Material And Methods: Sixty participants with normal hearing, comprising 30 MS patients and 30 healthy controls, were included.

Background: Cerebral small vessel disease (CSVD) is one of the most common nervous system diseases. Hypertension and neuroinflammation are considered important risk factors for the development of CSVD and white matter (WM) lesions.

Method: We used the spontaneously hypertensive rat (SHR) as a model of early-onset CSVD and administered epimedium flavonoids (EF) for three months.

Background: Diagnosing chronic inflammatory demyelinating polyneuropathy (CIDP) can be challenging, leading to delays in initiating therapy. As disability in CIDP is mainly dependent on axonal damage, the impact of delayed immunotherapy remains unclear. We multimodally investigated the clinical outcomes of patients with early CIDP regarding different treatment strategies and time points.

Demyelination, or the loss of myelin in the central nervous system (CNS) is a hallmark of multiple sclerosis (MS) and occurs in various forms of CNS injury and neurodegenerative diseases. The regeneration of myelin, or remyelination, occurs spontaneously following demyelination. The lysophosphatidylcholine (LPC)-induced focal demyelination model enables investigations into the mechanisms of remyelination, providing insight into the molecular basis underlying an evolving remyelinating microenvironment over a tractable time course.

Myelin injury occurs in brain ageing and in several neurological diseases. Failure of spontaneous remyelination is attributable to insufficient differentiation of oligodendrocyte precursor cells (OPCs) into mature myelin-forming oligodendrocytes in CNS demyelinated lesions. Emerging evidence suggests that peroxisome proliferator-activated receptor γ (PPARγ) is the master gatekeeper of CNS injury and repair and plays an important regulatory role in various neurodegenerative diseases.
