Introducing a New Method for Studying the Effects of Movement Synchrony in Virtual Reality.

Introduction: This study introduces a new method to create virtual reality (VR) environments for studying synchrony in human body movements and their prosocial effects. Previous studies have shown the positive effects of synchrony, but more controlled and ecologically valid paradigms are needed to explore these effects deeper and translate them to the therapeutic domain.

Methods: A total of 82 healthy subjects participated in this study.

A Comparative Evaluation of Error Processing Performance and its Relationship with Cognitive Function in Patients with Alzheimer's Disease, Individuals with Mild Cognitive Impairment, and Normal Controls Using the Event-Related Potentials.

Background: Some pathological changes occur in patients with Alzheimer's disease (AD) prior to the onset of clinical symptoms.

Objective: In the present study, we aimed to investigate the potential of event-related potential (ERP) components in error processing performance as a neuromarker of mild cognitive impairment (MCI) and transition to AD and their relation with cognitive functions.

Methods: We conducted an evaluation of 16 patients diagnosed with AD, 16 patients with MCI, and 15 normal controls using three subtests from the Cambridge Neuropsychological Testing Automated Battery (CANTAB).

Concurrent and Discriminant Validity of the Farsi Translation of the Social Responsiveness Scale-Second Edition (SRS-2) and Social Communication Questionnaire (SCQ).

Early detection of autism spectrum disorder (ASD) can lead to earlier intervention and greater improvement of children's quality of life and performance; hence, the use of screening tools is essential to facilitate the diagnosis process. The aim of the present study was to determine the clinical and differential validity of Social Responsiveness Scale-Second Edition (SRS-2) and Social Communication Questionnaire (SCQ) in a group of children and adolescents with autism spectrum disorder compared to a normal developmental group. The study was conducted in Roozbeh Hospital involving 52 children with ASD and 53 typically developing (TD) children, aged between 4-12 years.

Examining the Dominant Presence of Brain Grey Matter in Autism During Functional Magnetic Resonance Imaging.

Introduction: Autism spectrum disorder (ASD) is a neurodevelopmental disorder with symptoms appearing from early childhood. Behavioral modifications, special education, and medicines are used to treat ASD; however, the effectiveness of the treatments depends on early diagnosis of the disorder. The primary approach in diagnosing ASD is based on clinical interviews and valid scales.

Evaluating the Effects of Rivastigmine on Decision-Making in Patients with Mild Cognitive Impairment by Cambridge Neuropsychological Test Automated Battery (CANTAB); A Randomized, Double-Blind, Placebo-Controlled Trial.

Background: Decision-making is a complex process, and most studies showed that patients with mild cognitive impairment (MCI) make worse decisions than healthy people.

Objectives: This study aims to evaluate the effect of rivastigmine on the decision-making of MCI patients using the Cambridge Neuropsychological Test Automated Battery (CANTAB) tests.

Methods: The study was conducted at the Roozbeh Hospital neurology clinic, and 30 patients with mild cognitive impairment over 40 years old were randomly recruited to receive rivastigmine or placebo twice daily for 12 weeks.
