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. Her neuropsychological performance was evaluated by a neuropsychological test battery at initial examination. Deterioration in neuropsychological functions like interference effect and attention (Stroop Test TBAG form), verbal fluency and switching to other category (Verbal Fluency Test, /(VFT), verbal short term and long term memory and recognition (Auditory Verbal Learning Test, /(AVLT) was detected. In 9 months follow up period her complaints resolved. Initial neuropsychological deficits were also fully recovered at follow up. There was an increase in intelligence scores with increased ability to pay and sustain attention. She had better performance at Stroop Test TBAG form, VFT and AVLT which was similar to her normal peers'. In this case report, the clinical aspects of central nervous system involvement in mercury intoxication and protection from potential toxic effects of laboratory materials like mercury at schools were discussed. School administrators should be aware of and parents and students should be given necessary protective information

The Behavior Rating Inventory of Executive Function and Continuous Performance Test in Preschoolers with Attention Deficit Hyperactivity Disorder

Objective The aim of this study is to examine performance-based measures and behavioral ratings of executive functions (EF) as a component of preschool attention deficit hyperactivity disorder (ADHD). Methods Twenty-one 4-to-6-year-old children with ADHD and 52 children with no psychopathology, matched on age, gender, socioeconomic status, and parental education, were enrolled. Parents were interviewed with the use of The Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime version. The Conners' Kiddie Continuous Performance Test (K-CPT) was administered to the children, and the Behavior Rating Inventory of Executive Function-Preschool version (BRIEF-P) and the Conners' Parent Rating Scale-Revised/Short Form (CPRS-R/S) were filled out by the parents. Results All BRIEF-P and CPRS-R/S scores, the K-CPT measures of inattention and impulsivity were higher in the ADHD group. The CPRS-R/S ADHD index was strongly correlated with inhibition and related indexes in the BRIEF-P and was moderately correlated with inattention measures in the K-CPT. Conclusion The current study is one of the few to investigate the features of preschool ADHD with the use of behavioral ratings of EF and a performance-based measure. Our results suggest that the BRIEF-P was able to identify behavioral difficulties in inhibition and working memory and that the K-CPT identified difficulties indicating inattention. The findings of this study support the use of a combination of methods for a complete evaluation of preschoolers with inattentive and hyperactive/impulsive behavior, the application of rating scales for screening ADHD symptoms, and the measurement of behavioral correlates of EF, along with performance-based measures.PubMedWoSScopu
