Differentiation of memory processing stages and effect of demographic variables with alternative scoring approaches to the Rey auditory verbal learning test.

Background: The Rey Auditory Verbal Learning Test (RAVLT) is the third most popular verbal memory test and the tenth most frequently used neuropsychological test. The original scoring system of RAVLT does not differentiate stages of memory processing, but a recently developed composite scoring system has this potential. The objectives were to compare the two systems in terms of their capacity to differentiate the stages of memory processing and to study the effect of demographic variables on the learning trials (T) of the Turkish form of RAVLT (T-RAVLT).

More continuous flow, better learning? The effect of aortic valve opening in patients with left ventricular assist device.

Purpose: The aim of this study was to analyze neurocognitive function in patients who underwent continuous flow left ventricular assist device (LVAD) implantation.

Material And Method: This cross-sectional study included three groups: LVAD ( = 31), heart failure patients ( = 26), and healthy volunteers ( = 27). The Rey Auditory-Verbal Learning Test (RAVLT), Judgement of Line Orientation Test (JLOT), Trail Making Test (TMT), Stroop Color-Word Interference Test (SCWIT), Verbal Fluency Test (VFT), Symbol-Digit Modality Test (SDMT) were used to assess the neurocognitive functions.

Spontaneous age-related changes of attention in unmedicated boys with attention deficit hyperactivity disorder.

Neuropsychological, neuroanatomical, and electrophysiological studies have reported a steady increase in the different attention types until the age of 10 years. Moreover, differences between healthy control (HC) boys and those with attention deficit hyperactivity disorder (ADHD) become nonsignificant in late childhood. This cross-sectional study aimed to perform a comparative analysis of attentional processing in boys with ADHD and HC in the 6:00-10:11 years age range.

Using Neuropsychometric Measurements in the Differential Diagnosis of Specific Learning Disability.

Introduction: The aim of this study was to develop a neuropsychometric battery for the differential diagnosis of specific learning disability (SLD), with specific respect to attention deficit hyperactivity disorder (ADHD), and to help resolve the conflicting results in the literature by an integrative utilization of scores on both the Bannatyne categories and neuropsychological tests.

Methods: The sample included 168 primary school boys who were assigned to SLD (n=21), ADHD (n=45), SLD and ADHD (n=57), and control groups (n=45). The exclusion criteria were a neurological or psychiatric comorbidity other than ADHD, a level of anxiety and/or depression above the cutoff score, medication affecting cognitive processes, visual and/or auditory disorders, and an intelligence level outside the IQ range of 85-129.

Preventive drugs restore visual evoked habituation and attention in migraineurs.

Visual system pathway dysfunction has been postulated in migraineurs. We wanted to investigate if any difference exists interictally in visual attention and visual evoked habituation of frequently attacked migraineurs compared to the healthy control group. The effects of 3-month prophylactic migraine treatment on these parameters were also assessed.

Construct Validity of Auditory Verbal Learning Test.

Objective: Auditory Verbal Learning Test (AVLT) is frequently used in neuropsychology literature to comprehensively assess the memory. The test measures verbal learning as immediate and delayed free recall, recognition, and retroactive and proactive interference. Adaptation of AVLT to the Turkish society has been completed, whereas research and development studies are still underway.

The effect of temperament on the treatment adherence of bipolar disorder type I.

Background And Aims: Treatment adherence is one of the most important factors that may determine treatment response in patients with bipolar disorders (BD). Many factors have been described to be associated with treatment adherence in BD. Temperament that can influence the course of BD will have an impact on treatment adherence.

Electrical status epilepticus during sleep: a study of 22 patients.

Objective: The aim of this study was to evaluate the clinical and imaging characteristics, treatment results, and prognosis of patients with electrical status epilepticus during sleep (ESES).

Method: A total of 22 patients with ESES pattern on EEG were retrospectively studied.

Results: The first neurological symptoms were seen at a mean age of 4.

[Metallic mercury poisoning and neuropsychological effects: a case report].

Mercury is an extremely toxic heavy metal that can devastate central nervous system. We present the case of a 15 year old adolescent with mercury intoxication following 4 days of exposure to elemental mercury at home who was consulted by department of pediatrics with complaints of demonstrated emotional lability, memory impairment, disinhibition, and impulsivity. Olanzapin 2,5 mg/day was initiated.

Neurocognitive functions in children and adolescents with subclinical hypothyroidism.

Objective: Hypothyroidism is a metabolic condition that can lead to cognitive and behavioral deficits in children and adolescents. However, there is less evidence about subclinical hypothyroidism (SH) as a risk factor for neuropsychological disorders in childhood. The aim of this study was to evaluate cognitive functions like active/passive attention, maintaining attention, and response inhibition in pediatric patients with SH.

Memory difficulties of adult patients with shunted hydrocephalus: a clinical study.

Aim: The purpose of this prospective study was to describe memory problems of adult patients with hydrocephalus.

Material And Methods: The research group consisted of healthy adults (control group) and hydrocephlic adults (hydrocephalus group). The hydrocephalus group (n: 19) had no clinical signs or symptoms of increased intracerebral pressure.

Neuropsychological assessment of adult patients with shunted hydrocephalus.

Objective: This study is planned to determine the neurocognitive difficulties of hydrocephalic adults.

Methods: THE RESEARCH GROUP CONTAINED HEALTHY ADULTS (CONTROL GROUP, N : 15), and hydrocephalic adults (n : 15). Hydrocephalic group consisted of patients with idiopathic aquaduct stenosis and post-meningitis hydrocephalus.

Cognitive functions in neurofibromatosis type 1 patients and unaffected siblings.

Attention, learning, and perceptual problems have been reported at various degrees and rates in neurofibromatosis type 1 (NF1). We aimed to define the cognitive profiles frequently associated with NF1. Children and adolescents with NF1 (n=58) were tested using Wechsler Intelligence Scales for Children-Revised (WISC-R), Judgment of Line Orientation, and Bender Visual-Motor Gestalt tests.

Neurodevelopmental status of preterm newborns at infancy, born at a tertiary care center in Turkey.

Our objective was to determine the incidence of early neonatal problems and the neurodevelopmental status and probable risk factors associated with neurodevelopmental abnormality in preterm infants of < or = 32 weeks of gestation. Preterm newborns of < or = 32 weeks of gestation followed at the neonatal intensive care unit of the Department of Pediatrics of Gülhane Military Medical Academy, Ankara, Turkey, were evaluated with a complete neurological examination and the Bayley Scales of Infant Development at a mean age of 25.85 + or - 11.

Evaluation of the intellectual skill problems of hydrocephalic children: a clinical study.

Aim: This study is planned to determine the intellectual skill difficulties and attention problems of hydrocephalic children, and to compare them to children with attention deficit hyperactivity disorder (ADHD).

Material And Methods: The Wechsler Intelligence Scale for Children-Revised (WISC-R) test was applied to healthy children (control group), hydrocephalic children (hydrocephalus group) and children with ADHD (ADHD group); and the test results were statistically analyzed with the Multivariate Analysis of Variance (MANOVA) and linear logistic regression test.

Malformations of cortical development and epilepsy: evaluation of 101 cases (part II).

Malformations of cortical development (MCD) form a spectrum of lesions produced by insult to the developing neocortex. Clinical presentation and electrophysiologic findings of MCD are variable and depend on the affected cortical area. We evaluated epilepsy, EEG, and response to antiepileptic treatment in patients with MCD with respect to the neuroimaging findings.

Malformations of cortical development: clinical spectrum in a series of 101 patients and review of the literature (Part I).

Patients with malformations of cortical development (MCD) present with a wide spectrum of clinical manifestations ranging from asymptomatic cases to those with epilepsy and neurodevelopmental problems. Thorough clinical delineation of patients with MCD may provide clues for future phenotype-genotype correlation studies. We studied clinical features of patients with MCD, including developmental risk factors and family history.

Can preschool developmental screening identify children at risk for school problems?

Screening preschool children for potential school problems may allow early intervention. Children beginning first grade (N=980) were tested with Denver II. All with normal/questionable results had satisfactory school performance while 26% of those with abnormal Denver II had low school scores.
