Visual evoked potentials in children prenatally exposed to methylmercury.
Prenatal exposure to methylmercury can cause both neurobehavioral deficits and neurophysiological changes. However, evidence of neurotoxic effects within the visual nervous system is inconsistent, possibly due to incomplete statistical adjustment for beneficial nutritional factors. We evaluated the effect of prenatal methylmercury exposure on visual evoked potential (VEP) latencies in Faroese c...
متن کاملPattern Visual Evoked Potentials in Dyslexic Children
PURPOSE This study aimed to compare pattern visual evoked potential (PVEP) components in dyslexic and normal children. METHODS This cross-sectional analytic study recruited 72 children, including 36 dyslexic and 36 normal participants aged 8-12 years. Visual examinations included measurement of distance visual acuity, refraction, and PVEP components of amplitudes and latencies with two differ...
متن کاملLong-term neurocognitive outcomes of children prenatally exposed to low-dose methylmercury.
1. It has been suggested that lowdose prenatal mercury exposure as measured by umbilical cord blood mercury concentrations of >29 nmol/L causes adverse long-term neurocognitive outcomes. 2. Of 608 children, 491 (81%) had umbilical cord blood mercury concentrations of >29 nmol/L. However, umbilical cord blood mercury concentrations were associated with only two out of 23 neurocognitive subtests....
متن کاملDelayed brainstem auditory evoked potential latencies in 14-year-old children exposed to methylmercury.
OBJECTIVE To determine possible exposure-associated delays in auditory brainstem evoked potential latencies as an objective measure of neurobehavioral toxicity in 14-year-old children with developmental exposure to methylmercury (MeHg) from seafood. STUDY DESIGN Prospective study of a birth cohort in the Faroe Islands, where 878 of eligible children (87%) were examined at age 14 years. Latenc...
متن کاملInfluence of dopamine on flash visual evoked potentials (FVEP) in prenatally mercury intoxicated rats.
The female adult white Wistar rats were given tap water (control) or 50 ppm of methylmercury chloride (MMC) ad libitum throughout their pregnancies. Newborn rats drank mother's milk during the first 21 days after delivery and then only tap water. The study was carried out on three-month old offsprings of white Wistar rats. The flash visual evoked potentials (FVEP) were recorded before and after...
