Mismatch negativity contribution in multiple sclerosis patients.

Association of CD24V/V Genotype with Susceptibility and Progression of Multiple Sclerosis in Iranian Population

A single nucleotide polymorphism (SNP) in CD24 has been associated with multiple sclerosis (MS) in a population based study. This SNP results in the replacement of alanine (CD24A) by valine (CD24V) at amino acid 57 in the resulting polypeptide chain. In the current study, the genotyping of this SNP and its contribution to MS in 217 patients and 200 healthy individuals of an Iranian population w...

Contribution of Micronutrients Intake to the Risk of Multiple Sclerosis: Is the Available Evidence Convincing?

Mismatch negativity, social cognition, and functional outcomes in patients after traumatic brain injury

Mismatch negativity is generated automatically, and is an early monitoring indicator of neuronal integrity impairment and functional abnormality in patients with brain injury, leading to decline of cognitive function. Antipsychotic medication cannot affect mismatch negativity. The present study aimed to explore the relationships of mismatch negativity with neurocognition, daily life and social ...

Effects of Blocking D2/D3 Receptors on Mismatch Negativity and P3a Amplitude of Initially Antipsychotic Naïve, First Episode Schizophrenia Patients

BACKGROUND Reduced mismatch negativity and P3a amplitude have been suggested to be among the core deficits in schizophrenia since the late 1970s. Blockade of dopamine D2 receptors play an important role in the treatment of schizophrenia. In addition, there is some evidence indicating that deficits in mismatch negativity and P3a amplitude are related to increased dopaminergic activity. This is t...

Auditory mismatch negativity in schizophrenia: topographic evaluation with a high-density recording montage.

OBJECTIVE The mismatch negativity, a negative component in the auditory event-related potential, is thought to index automatic processes involved in sensory or echoic memory. The authors' goal in this study was to examine the topography of auditory mismatch negativity in schizophrenia with a high-density, 64-channel recording montage. METHOD Mismatch negativity topography was evaluated in 23 ...
