Objective: The primary objective of this study was to investigate the effect of methylphenidate (MPH) on height, weight, and body mass index (BMI) in drug-naive children and adolescents with attention deficit hyperactivity disorder (ADHD) over 24 months. The secondary objective was to investigate whether the age of MPH initiation and sex act as risk factors for growth retardation.

Methods: A total of 82 patients with ADHD were included.

Objective: The aim of this study was to verify the equivalence and effectiveness of the tablet-administered Korean Repeatable Battery for the Assessment of Neuropsychological Status (K-RBANS) for the prevention and early detection of dementia.

Methods: Data from 88 psychiatry and neurology patient samples were examined to evaluate the equivalence between tablet and paper administrations of the K-RBANS using a non-randomly equivalent group design. We calculated the prediction scores of the tablet-administered K-RBANS based on demographics and covariate-test scores for focal tests using norm samples and tested format effects.

Objective: This study aimed to validate the Korean version of the Repeatable Battery for the Assessment of Neuropsychological Status Update (K-RBANS).

Methods: We performed a retrospective analysis of 283 psychiatric and neurosurgery patients. To investigate the convergent validity of the K-RBANS, correlation analyses were performed for other intelligence and neuropsychological test results.

Active and prompt scale-up screening tests are essential to efficiently control the coronavirus disease 2019 (COVID-19) outbreak. The goal of this work was to identify shortcomings in the conventional screening system (CSS) implemented in the beginning of the outbreak. To overcome these shortcomings, we then introduced a novel, independently developed system called the Yeungnam University type drive-through (YU-Thru), and distributed it nationwide in Korea.

Objective: Physical or mental imbalance caused by harmful stimuli can induce stress to maintain homeostasis. During chronic stress, the sympathetic nervous system is hyperactivated, causing physical, psychological, and behavioral abnormalities. At present, there is no accepted standard for stress evaluation.

Objective: This study explored the relationships among demographic (DVs) and clinical variables (CVs), neurocognitive (NOs) and functional outcome (FO) that could be used as prognostic factors for old aged patients with traumatic brain injury (TBI) undergoing or appointed disability evaluation (DE) after treatment.

Methods: A total of 162 subjects with TBI above the age of 55 years undergoing DE or appointed to do so after treatments were selected. The patients were divided into two subgroups according to age : a junior elderly group 55 to 64 years old and a senior elderly group over the age of 65.

Various neurological problems of the brain are known to occur in patients with end stage renal disease (ESRD). However, little is known about diffusion tensor imaging (DTI) findings in patients with ESRD. Using DTI, we attempted to investigate DTI findings in patients with ESRD who showed no specific lesions on conventional brain MRI.

Objective: We investigated whether Disability Evaluation (DE) situations influence patients' neuropsychological test performances and psychopathological characteristics and which variable play a role to establish an explanation model using statistical analysis.

Methods: Patients were 536 (56.6%) brain-injured persons who met inclusion and exclusion criteria, classified into the DE group (DE; n = 300, 56.

Objective: We investigated executive functions (EFs), as evaluated by the Wisconsin Card Sorting Test (WCST), and other EF between lower grades (LG) and higher grades (HG) in elementary-school-age attention deficit hyperactivity disorder (ADHD) children.

Methods: We classified a sample of 112 ADHD children into 4 groups (composed of 28 each) based on age (LG vs. HG) and WCST performance [lower vs.

Article Synopsis
  • Scientists studied how injuries to a specific pathway in the brain (called the spino-thalamo-cortical pathway, or STP) might cause pain (known as central post-stroke pain, or CPSP) in patients who had bleeding in the brain.
  • They looked at 30 patients and grouped them based on whether they had CPSP or not, and measured different things about their brain pathways.
  • The results showed that patients with CPSP had less volume in the STP compared to those without, suggesting that injury to this pathway may be involved in causing the pain after a stroke.

Article Synopsis
  • The study looked at how injuries to a part of the brain called the fornix affect memory in people with diffuse axonal injury (DAI).
  • Nine patients with DAI and nine healthy people were compared using special brain imaging called diffusion tensor imaging (DTI).
  • The results showed that patients with DAI had less healthy brain connections in the fornix body, and this was linked to their memory problems.

Objective: The purpose of this study was to assess memory dysfunction in patients with mild and moderate traumatic brain injury (TBI) with and without frontal lobe injury (FLI).

Methods: The subjects were 110 TBI patients, who had recovered from the acute clinical phase, and comprised 20 (18.2%) mild TBI (MTBI) patients with FLI, 16 (14.

Objective: Premorbid demographic backgrounds of injured individuals are likely to reflect more accurately the status of patients with traumatic brian injury (TBI) than clinical factors. However, the concrete study about the relationship between the demographic factors and neurocognitive function in TBI patients has not been reported. The object of this study was to evaluate the effect of premorbid demographic factors on the recovery of neurocognitive function following TBI.

Objectives: Constraint-induced movement therapy (CIMT) has been demonstrated to be effective in improving hemiparetic upper extremity function in stroke patients, but few studies have been performed to assess orthosis modification. We investigated the effect of the newly designed small orthosis named modified opposition restriction orthosis (MORO) in chronic hemiparetic patients with stroke.

Design: Twenty-one stroke patients were randomly assigned to the CIMT group or control group.

Objective: This study was conducted to evaluate the effectiveness of aripiprazole to reduce the severity and frequency of tic symptoms and to evaluate the additional effects of aripiprazole on weight changes in children and adolescents with Tourette disorder (TD) or chronic tic disorders.

Methods: A 12-week, open-label trial with flexible dosing strategy of aripiprazole was performed with 15 participants, aged 7-19 years. The Yale Global Tic Severity Scale was applied and the baseline, week 3, 5, 9, and end point scores were compared.

Article Synopsis
  • Researchers studied 3 patients with brain damage in a part called the pons to understand how their movement control works.
  • They used special imaging techniques to see the pathways that help with movement in the brain.
  • They found that the patients’ ability to move was mostly managed by a part of the brain that wasn’t damaged, even though there was some injury nearby.
