BACKGROUND: The four measures used to assess the stability of the Wisconsin card sorting test (WCST), that is, the number of preservative errors, percentage of preservative errors, number of categories completed, and the number of trials to complete the first category, reflect the function of the frontal lobe.
OBJECTIVE: This study was designed to investigate the effects of asthma on the stability of WCST measurements through the use of a twin study, and to analyze whether egg-type difference exists.
DESIGN: A cohort study.
SETTING: Mental Health Center, the First Affiliated Hospital of Chongqing Medical University.
PARTICIPANTS: Fifty-nine pairs of twins, aged 6-16 years, were primarily selected from schools between August 2005 and February 2007 and the WCST and Zygosity identification test was applied. Twins with achromatopsia, severe upper limb diseases, somatic diseases, or mental disorders were excluded. According to disease history of asthmatic attack, children were assigned into asthma (n = 16) and non-asthma (n = 43) groups.
METHODS: Four WCST measurements were determined in the 59 pairs of twins, and egg-type differences were identified in conjunction.
RESULTS: All 59 pairs of twins were included in the final analysis. Among the pairs of twins, 28 (48.5 %) were monozygotic twins, and 31 (52%) were dizygotic twins. Among the monozygotic and dizygotic twins, the number of preservative errors and percentage of preservative errors were significantly higher in the asthma group than in the non-asthma group (P 〈 0.05). However, there was no significant difference of each corresponding measure between the monozygotic and dizygotic twins (P 〉 0.05).
CONCLUSION: Asthma may affect the stability of WCST measures, but egg-type differences do not exist. 相似文献

BACKGROUND: Methamphetamine (MA) abusers have cognitive deficits, abnormal metabolic activity and structural deficits in limbic and paralimbic cortices, and reduced hippocampal volume. The links between cognitive impairment and these cerebral abnormalities are not established. METHODS: We assessed cerebral glucose metabolism with [F-18]fluorodeoxyglucose positron emission tomography in 17 abstinent (4 to 7 days) methamphetamine users and 16 control subjects performing an auditory vigilance task and obtained structural magnetic resonance brain scans. Regional brain radioactivity served as a marker for relative glucose metabolism. Error rates on the task were related to regional radioactivity and hippocampal morphology. RESULTS: Methamphetamine users had higher error rates than control subjects on the vigilance task. The groups showed different relationships between error rates and relative activity in the anterior and middle cingulate gyrus and the insula. Whereas the MA user group showed negative correlations involving these regions, the control group showed positive correlations involving the cingulate cortex. Across groups, hippocampal metabolic and structural measures were negatively correlated with error rates. CONCLUSIONS: Dysfunction in the cingulate and insular cortices of recently abstinent MA abusers contribute to impaired vigilance and other cognitive functions requiring sustained attention. Hippocampal integrity predicts task performance in methamphetamine users as well as control subjects. 相似文献

The Wisconsin card sorting test and the Weigl test are two neuropsychological tools widely used in clinical practice to assess
frontal lobe functions. In this study we present norms useful for Italian subjects aged from 15 to 85 years, within 5–17 years
of education. Concerning the Wisconsin card sorting test, a new measure of global efficiency (global score) is proposed as
well as norms for some well known, qualitative aspects of the performance, i. e. perseverative responses, failure to maintain
the set and non-perseverative errors. In setting normative values, we followed a statistical methodology (equivalent scores)
employed in Italy for other neuropsychological tests, in order to favour the possibility of comparison among these tests.
A correlation study between the global score of the Wisconsin card sorting test and the score on the Weigl test was carried
out and it emerges that some cognitive aspects are not overlapping in these two measures.

Chronic use of methamphetamine is related to behavioral disturbances including depression, aggressive behavior, and social isolation. These alterations of social behavior may be attributable to impairments in social cognition. However, few studies have evaluated social cognition in methamphetamine (MA) abusers. Therefore, the aim of the present study was to investigate whether MA abusers exhibit social cognition deficits in terms of facial emotion recognition and theory of mind (ToM). We also assessed cognitive flexibility by using the Wisconsin Card Sorting Test (WCST) to evaluate the impact of this function on social cognition. Twenty-eight MA abusers and twenty-seven healthy subjects enrolled in this study. All participants performed the Facial Emotion Recognition Task and advanced ToM tasks such as the Eye Test and Hinting Task. The Korean Wechsler Adult Intelligence Scale—Revised and computerized versions of the WCST were also administrated. The performances of MA abusers on the Facial Emotion Recognition Task and Eyes Test were lower than those of healthy subjects. In the WCST, MA abusers completed significantly fewer categories and made more total and perseverative errors than healthy subjects did. In addition, impairments in cognitive flexibility are correlated with impairments in facial emotion recognition and ToM within MA abusers. These findings lend further support to the assertion that the capacity to identify emotions from facial expression and infer mental state of others is impaired in MA abusers. Therefore, treatment and rehabilitation for MA abusers must consider role of social cognition and include relearning social interactions and behaviors. 相似文献

Transcranial magnetic stimulation has evolved into a powerful neuroscientific tool allowing to interfere transiently with specific brain functions. In addition, repetitive TMS (rTMS) has long-term effects (e.g. on mood), probably mediated by neurochemical alterations. While long-term safety of rTMS with regard to cognitive functioning is well established from trials exploring its therapeutic efficacy, little is known on whether rTMS can induce changes in cognitive functioning in a time window ranging from minutes to hours, a time in which neurochemical effects correlated with stimulation have been demonstrated. This study examined effects of rTMS on three measures of executive function in healthy subjects who received one single rTMS session (40 trains of 2 s duration 20 Hz stimuli) at the left dorsolateral prefrontal cortex (DLPFC). Compared to a sham condition one week apart, divided attention performance was significantly impaired about 30-60 min after rTMS, while Stroop-interference and performance in the Wisconsin Card Sorting Test was unaffected after rTMS. Repetitive TMS of the left DLPFC, at stimulation parameters used in therapeutic studies, does not lead to a clinically relevant impairment of executive function after stimulation. However, the significant effect on divided attention suggests that cognitive effects of rTMS are not limited to the of acute stimulation, and may possibly reflect known neurochemical alterations induced by rTMS. Sensitive cognitive measures may be useful to trace those short-term effects of rTMS non-invasively in humans. 相似文献

BACKGROUND: Little is known about structural brain abnormalities associated with methamphetamine (METH) abuse; therefore, we aimed: 1) to evaluate possible morphometric changes, especially in the striatum of recently abstinent METH-dependent subjects; 2) to evaluate whether morphometric changes are related to cognitive performance; and 3) to determine whether there are sex-by-METH interactions on morphometry. METHODS: Structural MRI was performed in 50 METH and 50 comparison subjects with the same age range and sex proportion; quantitative morphometric analyses were performed in the subcortical gray matter, cerebellum and corpus callosum. Neuropsychological tests were also performed in 44 METH and 28 comparison subjects. RESULTS: METH users showed enlarged putamen (left: + 10.3%, p = .0007; right: + 9.6%, p = .001) and globus pallidus (left: + 9.3%, p = .002; right: + 6.6%, p = .01). Female METH subjects additionally showed larger mid-posterior corpus callosum (+ 9.7%, p = .05). Although METH users had normal cognitive function, those with smaller striatal structures had poorer cognitive performance and greater cumulative METH usage. CONCLUSIONS: Since METH subjects with larger striatal structures had relatively normal cognitive performance and lesser cumulative METH usage, the enlarged putamen and globus pallidus might represent a compensatory response to maintain function. Possible mechanisms for the striatal enlargement include glial activation and inflammatory changes associated with METH-induced injury. 相似文献

Anxiety and depression are the most common withdrawal symptoms of methamphetamine (METH) abuse, which further exacerbate relapse of METH abuse. To date, no effective pharmacotherapy exists for METH abuse and its withdrawal symptoms. Therefore, understanding the neuromechanism underlying METH abuse and its withdrawal symptoms is essential for developing clinical strategies and improving patient care. The aims of this study were to investigate brain network abnormalities in METH abusers (MAs) and their associations with affective symptoms. Forty‐eight male abstinent MAs and 48 age‐gender matched healthy controls were recruited and underwent resting state functional magnetic resonance imaging (fMRI). The severity of patient anxiety and depressive symptoms were measured by Hamilton anxiety and depression rating scales, which decreased across the duration of abstinence. Independent component analysis was used to investigate the brain network functional connectivity (FC) properties. Compared with healthy controls, MAs demonstrated hypo‐intra‐network FC in the cerebellar network and hyper‐intra‐network FC in the posterior salience network. A whole‐brain regression analysis revealed that FC strength of clusters located in the right rostral anterior cingulate cortex (rACC) within the ventromedial network (VMN) was associated with affective symptoms in the patients. Importantly, the intra‐network FC strength of the rACC in VMN mediated the association between abstinence duration and the severity level of affective symptoms. Our results demonstrate alterations in brain functional networks underlying METH abuse, and that the FC of rACC within VMN serve as a neural substrate in the association between abstinence length and affective symptom severity in the MAs. 相似文献

Migraine is one of the most common medical disorder in the world. Metacognition is the ability to monitor one’s own cognitive functioning and consequently direct one’s behavior. In adult migraine patients, the neuropsychological profile has been poorly investigated, and metacognitive functions have never been assessed. The aim of the present study was therefore to evaluate executive metacognitive abilities in patients with episodic and chronic migraine. Sixty-four migraine patients (male/female = 18/46; mean age = 45.65 ± 11.61 years): 27 patients with episodic migraine without aura (male/female = 9/18; mean age ± SD = 45.11 ± 12.18 years) and 37 patients with chronic migraine and medication-overuse headache (male/female = 9/28; mean age ± SD = 46.05 ± 11.32 years) were selected for the study. Twenty-nine controls (male/female = 12/17; mean age ± SD = 42.86 ± 14.78 years) were also enrolled in the research. Metacognitive and executive skills were assessed using the metacognitive version of Wisconsin Card Sorting Test. Migraine patients exhibited a lower performance in metacognitive tasks in respect to controls in term of worse outcomes in accuracy score (p = 0.012), global monitoring (p = 0.015), monetary gains (p = 0.022), and control sensitivity (p = 0.027). A reduction in accuracy score (p = 0.001), free-choice improvement (p = 0.002), global monitoring (p = 0.003), monetary gains (p = 0.009), and control sensitivity (p < 0.001) was also found in patients with chronic migraine and medication-overuse headache in respect to patients with episodic migraine. Our study supports the hypothesis that migraine patients show metacognitive dysfunctions that become worse with the chronicization of the disease and the increase of medication use. 相似文献

Motor symptoms in Gilles de la Tourette syndrome (GTS) have been related to changes in frontostriatal brain networks. These changes may also give rise to alterations in cognitive flexibility. However, conclusive evidence for altered cognitive flexibility in patients with GTS is still lacking. Here, we meta-analyzed data from 20 neuropsychological studies that investigated cognitive flexibility in GTS using the Wisconsin Card Sorting Test (WCST). Results revealed medium-sized GTS-related performance deficits, which were significantly modulated by age: Whilst being substantial in children and adolescents with GTS, WCST deficits seem to dissolve in adult patients with GTS. This age-related normalization of WCST performance might result from the compensatory recruitment of cognitive control in adult patients with GTS. We addressed this possibility by examining neural correlates of proactive and reactive cognitive control in an event-related potential (ERP) study. We analyzed cue- and target-locked ERPs from 23 adult patients with GTS and 26 matched controls who completed a computerized version of the WCST. Compared to controls, patients with GTS showed a marked increase in parietal cue-locked P3 activity, indicating enhanced proactive cognitive control. We conclude that the additional recruitment of proactive cognitive control might ensure flexible cognitive functioning in adult patients with GTS. 相似文献

The Wisconsin card sorting test (WCST) comprehensively examines executive function (EF). The Keio version of the WCST (KWCST) uses fewer cards and presents them in two steps, separated by a short pause during which an instruction is given. Being of short duration, this test is suitable for children with pervasive developmental disorder (PDD) and attention-deficit/hyperactivity disorder (AD/HD), yet few studies have examined the performance of children with such developmental disorders in the second step of a two-step test such as the KWCST. Using the KWCST, this study compares EF in children with PDD (n=52), or AD/HD (n=46) to that in typically developing (TD) children (n=52). Scores for the six indices of this test, including numbers of response cards until the first category achieved (NUCA), total errors (TE), and non-perseverative errors of Nelson (NPEN), were analyzed using ANOVA. Compared to the TD group, scores in the PDD and/or AD/HD groups were significantly lower for all indices except NUCA and NPEN for the first step, and lower for all indices except NUCA for the second step. Moreover, significantly fewer improvements in TE were seen in the PDD group, and significantly fewer improvements in NPEN were seen in the AD/HD group, compared with TD. This study suggests that both PDD and AD/HD make it difficult for children to utilize their experience in the first step and to effectively apply the instruction given before the second step. It also suggests that the two-step nature of the KWCST is clinically important. 相似文献

Persistent neurochemical abnormalities in frontal brain structures are believed to result from methamphetamine use. We developed a localized 13C magnetic resonance spectroscopy (MRS) assay on a conventional MR scanner, to quantify selectively glial metabolic flux rate in frontal brain of normal subjects and a cohort of recovering abstinent methamphetamine abusers. Steady-state bicarbonate concentrations were similar, between 11 and 15 mmol/L in mixed gray-white matter of frontal brain of normal volunteers and recovering methamphetamine-abusing subjects (P>0.1). However, glial 13C-bicarbonate production rate from [1-13C]acetate, equating with glial tricarboxylic acid (TCA) cycle rate, was significantly reduced in frontal brain of abstinent methamphetamine-addicted women (methamphetamine 0.04 μmol/g per min (N=5) versus controls 0.11 μmol/g per min (N=5), P=0.001). This is equivalent to 36% of the normal glial TCA cycle rate. Severe reduction in glial TCA cycle rate that normally comprises 10% of total cerebral metabolic rate may impact operation of the neuronal glial glutamate cycle and result in accumulation of frontal brain glutamate, as observed in these recovering methamphetamine abusers. Although these are the first studies to define directly an abnormality in glial metabolism in human methamphetamine abuse, sequential studies using analogous 13C MRS methods may determine ‘cause and effect'' between glial failure and neuronal injury. 相似文献
