ObjectivesAlthough the majority of head-injured children are Glasgow Coma Scale (GCS) 15 and do not require admission or further investigations there is evidence that some children with a minor head injury (MHI) will go on to experience significant morphological and functional brain deficits. In view of the lack of controlled studies into the sequelae of MHI in children we carried out a pilot study that examined the neuropsychological performance in children who had sustained an MHI.MethodsChildren aged 6–12 years who presented to the Emergency Department of the Royal Hospital for Sick Children in Edinburgh with a MHI (GCS 15) were recruited to the study. Neuropsychological assessment was performed using the Cambridge Neuropsychological Test Automated Battery (CANTAB); a computerised battery of tests, which measures motor skills, visual attention, spatial memory, working memory and non-verbal memory span. CANTAB also assesses executive function, which is the highest level of cognitive function that manages planning and allows flexible thought and action.Results15 head-injured children were recruited over the study period (eleven boys and four girls). A 2 (subject groups) × 3 (time points) repeated measures Analysis of variance was used on the number of problems solved using the minimum number of computer moves at each time point, which showed a significant interaction (p=0.003). Bonferroni posthoc comparisons demonstrated that in week 1 the head-injured group were significantly lower in performance compared to normative data (p=0.03), but significantly increased in performance between week 1 and 12 months (p=0.0001). The difference in the head-injured group performance between week 1 and week 6 approached significance (p=0.05).ConclusionThe MHI group show a significantly poorer performance with regards to problem-solving in a minimum number of moves, which may indicate impulsive tendencies and insufficient planning ability. Children with a MHI may therefore be at risk of developing problems with high-level cognitive function postinjury.

AbstractNeuropsychological data on an extended series of cases of variant Creutzfeldt-Jakob Disease (vCJD) are presented, complementing earlier findings from smaller sample studies of this condition. Distinct neuropsychological features in this extended series included relatively preserved verbal knowledge, immediate verbal memory span, and elementary visual processing. This sparing contrasted with ubiquitous impairment in every vCJD patient on timed tests of verbal fluency and digit-symbol substitution. There were also high rates of impairment on tests of memory, and of visuoperceptual and visuospatial reasoning. Our findings lend support to the view that distinctive neuropsychological features may be one of the diagnostic markers of the condition. (JINS, 2009, 15, 807–810.)

Background. We wished to assess the effect of three types of medication on verbal memory impairments in schizophrenia.Method. Forty-eight patients with schizophrenia and 40 healthy control subjects underwent a battery of verbal memory tasks, including free recall, recognition and short-term memory span. All the patients were on antipsychotic medication. In addition, 24 were taking anticholinergic drugs (benztropine) and 30 were taking benzodiazepines. A subsample of 39 had clinical ratings for depressive symptoms. Regression analyses were conducted on the memory measures in this subsample, with negative symptoms, depression, type of antipsychotic medication (conventional v. atypical), benzodiazepines and anticholinergic drugs as predictors.Results. Type of antipsychotic medication made no significant contribution to memory deficits and benzodiazepine use made very little contribution. However, anticholinergic medication was a predictor of memory impairment, especially with regard to semantic organization. Complementary analyses revealed that patients taking any type of drug with anticholinergic activity (benztropine and/or antipsychotic agents) were significantly impaired relative to the other patients on measures reflecting free recall efficiency and semantic organization.Conclusions. Drugs with anticholinergic activity are the major pharmacological agents that contribute to the verbal memory deficit observed in patients with schizophrenia. These drugs appear to act by impeding semantic organization at encoding.

Spatial Locations

In studies of verbal memory span individual differences in speech rate have been found to predict the number of items that can be recalled in order. This is thought to happen because overt speech rate is related to the rate of internal verbal rehearsal. For spatial span there may also be an internal rehearsal system linked to overt responding, and if there is a strong analogy to be drawn between the verbal and spatial domains, then movement time between spatial targets should predict the number of spatial locations that can be recalled. In the first study reported, none of the six measures of movement time did predict spatial span, but, as expected, speech rate predicted verbal span. In addition, speech rate predicted spatial span. In a second study the use of articulatory suppression during span presentation showed that verbal span dropped, but was still predicted by speech rate. Spatial span was again predicted by the time it took to say digits rather than the time it took to make movements to spatial targets. There would not seem to be any simple analogy between the limitations on verbal span and those on spatial span. In addition, the relationship between speech rate and sequential memory performance may be more complex than previous studies have suggested.
