Design, To assess the neuropsychological outcome of children with asymmetric ventricles and unilateral ventriculomegaly identified in utero. Setting, Fetal neurology clinic. Population, We assessed 21 children with asymmetric ventricles (group 1) and 20 children with unilateral ventriculomegaly (group 2) identified in utero and compared them with a group of 20 children with symmetric ventricles using a formal neuropsychological tool: the Bayley Scale of Infant Development II (BSID-II). Main outcome measures, The group of children with unilateral ventriculomegaly scored significantly lower than the control group on the mental developmental index (MDI) and on the behaviour rating scale (BRS) but not on the psychomotor index. The group of children with asymmetric ventricles did not differ significantly from the control group on either the MDI or psychomotor developmental index but differed from the latter on the BRS. Fifteen percent of the children in the asymmetric ventriculomegaly group performed two SDs below average compared with 4% of children in the asymmetrical ventricles group and none of the control. Conclusion, Our results indicate that prenatally observed unilateral ventriculomegaly is a significant risk factor for developmental delay. The mental and motor outcome of children with asymmetric ventricles is similar to that of the control group, but these children are at a significant risk for behavioural abnormalities. [source]


One-year treatment of Alzheimer's disease with acetylcholinesterase inhibitors: improvement on ADAS-cog and TMT A, no change or worsening on other tests

Abstract The aim of this study was to assess cognitive functioning measured by selected psychometric and neuropsychological tools in patients with Alzheimer's disease (AD) after 1-year treatment with acetylcholinesterase inhibitors. Seventy-six patients (22 male and 54 female) with a mild to moderate stage of AD, aged 56,86 (mean 68) years, were treated. Forty-seven received donepezil (mean dose 9.3,mg/d) and 29 rivastigmine (mean dose 8.5,mg/d). Cognitive measurements included: the mini mental state examination (MMSE), the Alzheimer disease assessment scale-cognitive (ADAS- cog), the trail making test (TMT) and the Stroop color word interference test. The assessments were made before and after 3, 6 and 12 months of treatment. A significant improvement in ADAS-cog (p,<,0.001, 83% of patients improved) and a worsening in MMSE (84% of patients worsened, p,<,0.01 after 6 and 12 months) was noted after the 1 year treatment. A majority of patients (57%) improved in the TMT-A (p,<,0.001), measuring psychomotor speed and worsened in the TMT-B (p,<,0.01, after 12 months), and Stroop B test (p,<,0.001), measuring working memory and executive functions, 53% and 61%, respectively. Most patients (83%) did not change their performance in the Stroop A (improvement after 3 months, p,<,0.001, worsening after 6 and 12 months p,<,0.01) test measuring verbal abilities, after 1 year treatment. The results obtained suggest that the treatment with cholinergic drugs may improve global cognitive functioning (ADAS-cog) and psychomotor speed (TMT A), however, such treatment is unable to prevent the deterioration of working memory and executive functions.

Amantadine for traumatic brain injury: does it improve cognition and reduce agitation?

JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 2 2005
H. Leone PharmD
Summary Objective:, To review the available literature pertaining to amantadine as therapy for improving cognition and reducing agitation following a non-penetrating traumatic brain injury (TBI). Data sources:, Clinical literature was accessed through MEDLINE (from 1966 to February 2004) and bibliographic searches. Key search terms included ,amantadine', ,traumatic brain injury', ,cognition', and ,agitation'. Data synthesis:, Amantadine is primarily used for treatment and prophylaxis of influenza A. Its ability to improve mentation and motor function in patients with head injury remains questionable. An evaluation of five clinical trials, two case reports, and one case series is conducted focusing on the use of amantadine following TBI. Patients in clinical trials were assessed using a variety of neuropsychological tools aimed at, among other things, assessing cognition and agitation. Although individual patient results varied, the majority of patients studied showed improved neuropsychological test scores. Similar observations are noted in the case reports and case series. Improvement in cognition and reduced agitation seems to occur with post-injury amantadine therapy. Conclusions:, Amantadine is a reasonable option for improving cognition and reducing agitation following a TBI but confirmatory evidence of the efficacy the drug is necessary. [source]


Timing of Thyroid Hormone Action in the Developing Brain: Clinical Observations and Experimental Findings

JOURNAL OF NEUROENDOCRINOLOGY, Issue 10 2004
R. T. Zoeller
Abstract The original concept of the critical period of thyroid hormone (TH) action on brain development was proposed to identify the postnatal period during which TH supplement must be provided to a child with congenital hypothyroidism to prevent mental retardation. As neuropsychological tools have become more sensitive, it has become apparent that even mild TH insufficiency in humans can produce measurable deficits in very specific neuropsychological functions, and that the specific consequences of TH deficiency depends on the precise developmental timing of the deficiency. Models of maternal hypothyroidism, hypothyroxinaemia and congential hyperthyroidism have provided these insights. If the TH deficiency occurs early in pregnancy, the offspring display problems in visual attention, visual processing (i.e. acuity and strabismus) and gross motor skills. If it occurs later in pregnancy, children are at additional risk of subnormal visual (i.e. contrast sensitivity) and visuospatial skills, as well as slower response speeds and fine motor deficits. Finally, if TH insufficiency occurs after birth, language and memory skills are most predominantly affected. Although the experimental literature lags behind clinical studies in providing a mechanistic explanation for each of these observations, recent studies confirm that the specific action of TH on brain development depends upon developmental timing, and studies informing us about molecular mechanisms of TH action are generating hypotheses concerning possible mechanisms to account for these pleiotropic actions.
