[Epilepsy and intelligence. I. Intellectual status in a group of 215 ambulatory patients].

A group of 119 men and 96 women, mean age 32.8 years, with a mean onset of the disease at the age 13 years was examined by Wechsler's intelligence test for adults (Wechsler-Bellevue). They assessed the mean intellectual level, total IQ mean = 104.4, s = 15.3. The intellectual performance of female patients had roughly a normal distribution, in men it was shifted slightly to higher zones. The mean absolute difference of the verbal IQ and performance IQ was mean = 8.4, s = 7.0, median = 7. The results are consistent with some more recent data in the literature on good intellectual abilities of the majority of epileptic subjects. The authors discuss the causes of frequent erroneous ideas of laymen and health professionals on an association of epilepsy and intellectual inadequacy. Among others there persists prejudice, problems of patients as regards memory, problems in the psychosocial sphere, psychopathological manifestations, adverse side-effects of drugs, sequelae of transient impairment of consciousness manifested clinically by short-term reduced performance. Real impairment of epileptic patients are assessed best by special neuropsychological methods, however, evaluation of intellectual abilities is necessary.

Psychiatric disorder in children with birth anomalies. A retrospective follow-up study.

A group of 273 children and adolescents, aged 8 to 19 years, who had been treated for a congenital malformation during their 1st month of life, were studied using psychiatric interviews with the child and at least one of his parents. The child was also given a Wechsler intelligence test. The rate of psychopathological disturbance was as high as 49% (the classification used included organic brain disorder and mental retardation). Developmental deviations, psychoneurotic disorder and reactive disorder were the commonest types of disturbance (in 18, 17, and 11% respectively). Eleven percent were suffering from organic brain disorder and 8% had an IQ of no more than 50. The malformed children were compared with 509 children from the general population in terms of behaviour disturbance as rated by their teacher. Approximately one child in five in both groups presented behaviour problems, and behaviour was labelled as antisocial in 10% of children in both groups. The two groups of children did not differ significantly in regard to the family's social class, annual income, father's educational background, or the number of children in the family, but the parents of the malformed children had recieved psychiatric treatment more often than the control group parents.

Associations of birth defects with adult intellectual performance, disability and mortality: population-based cohort study.

Infants born with birth defects have poorer outcomes in terms of mortality and disability, but the long-term intellectual outcome in children with birth defects is generally unknown. We assessed the long-term associations of various birth defects with mortality and disability, and evaluated whether high mortality and disability were reflected in impaired intellectual performance at age 18. In this nationwide cohort study, records of 9,186 males with and 384,384 without birth defects, registered in the Medical Birth Registry of Norway (1967-1979) were linked to the National Conscript Service (1984-1999). Mortality and disability before military draft, and intelligence test score at conscription were the main outcome measures. Males with birth defects had a relative risk for disability of 6.0 compared with males without defects. Disability was low within categories of birth defects associated with low mortality, and high within defect categories associated with high mortality. The relative risk for not being drafted was highest if maternal educational level was low. Heart defects and cleft palate were the only subgroups in which intellectual performance was lower after adjustment for maternal education, maternal age, marital status and birth order. In particular, intellectual performance was not impaired among those with multiple compared with single defects. We conclude that for the majority of birth defect categories in the present birth cohort, our hypothesis that intellectual performance would be impaired was not confirmed. Thus, there seems to be little reason to fear an adverse intellectual outcome in non-disabled surviving infants with birth defects.

Galvanic skin response of oral cancer patients during speech.

Severe speech difficulty is often caused after surgery of an oral cancer. Prosthetic treatment with a removable obturator prosthesis is generally provided for such patients. Although some speech ability is recovered with prosthetic treatment, patients sometimes complain of continued dissatisfaction with their speech. However, it is difficult to evaluate the dissatisfaction. Therefore, a new method for evaluation is desirable. In this study, such a new method using the galvanic skin response as the index for the dissatisfaction of the patient was developed, and its objectivity was investigated. Eleven patients with maxillary bone defects were selected. Prior to the evaluation, improvement of speech with the removable prosthesis was confirmed using the speech intelligibility test and the visual analogue scale. The electrical resistant value at pronunciation was measured with the measuring system composed with the apparatus (galvanic skin response (GSR) measuring apparatus), the personal computer program. The changes for the electrical resistant value after pronunciation were evaluated by calculating the decrease ratio at pronunciation [(the mean electrical resistance before pronunciation - the mean electrical resistance after pronunciation)/the mean electrical resistance before pronunciation]. This decrease ratio at pronunciation was defined as the index of the speech dissatisfaction of the subject. The mean values for the decrease ratio with prosthesis were significantly smaller than the values without prosthesis (P < 0.05). From the results of this study, it is suggested that the measurement of the electrical resistance change of the skin during speech could be a new method for evaluating the speech dissatisfaction of the post-oral-cancer patient.

Girls with fragile X syndrome: physical and neurocognitive status and outcome.

The fragile X syndrome, a common X-linked form of mental retardation and autism, affects females as well as males. Previous work has shown that approximately 35% of heterozygotes (women who carry the fragile X gene) demonstrate cognitive impairment. Thirty-two girls, 18 years or younger, who demonstrate the fragile X chromosome were evaluated and compared with 19 sisters who do not demonstrate the fragile X chromosome. Evaluations included a physical examination, behavioral assessment, and intelligence testing. Significant differences (in intellectual, behavioral, and physical features) were seen between the two groups. Twenty-five percent of fragile X-positive girls had an IQ in the mentally retarded range (IQ less than 70) and 28% had an IQ in the borderline range (70 to 84). Prominent ears, shyness, and poor eye contact were significant findings in fragile X-positive girls compared with fragile X-negative girls. Thirty-one percent of the fragile X-positive girls had significant attentional difficulties and most of these girls were successfully treated with stimulant medication. The majority of fragile X-positive girls in this study demonstrated significant behavioral and developmental problems which required identification and appropriate treatment. Pediatricians and health care providers should be aware of the frequency and manner with which fragile X affects females in order to initiate cytogenetic studies and treatment when indicated.

[Reconstruction of speech and chewing function after extensive tumor resection in the area of the jaw and face].

BACKGROUND: Following extensive resections of head and neck tumors, re-establishing speech and masticatory function are of crucial importance for the patient. METHODS: In 23 patients with vascularised jejunal grafts for reconstruction of the intraoral mucosa, tongue and floor of mouth, a speech intelligibility test was performed, tongue and floor of mouth mobility was investigated using a 3.5 MHz ultrasound scanner. In another 18 patients with vascularised bone grafts for reconstruction of the mandible, masticatory function was analysed using a T-scan system and a miniature pressure transducer. RESULTS: Speech results with jejunal grafts in the lateral floor of mouth/tongue region may attain 91.4%, in anterior floor of mouth reconstructions 63.4%. Patients with implant-bone dentures and vascularised bone grafts prefer the non-reconstructed side for chewing. Masticatory force is significantly diminished compared to a control group. DISCUSSION: Lack of neurosensitive feedback mechanisms may be responsible for diminished chewing pressure and also for inferior speech results despite good floor-of-mouth/tongue mobility. CONCLUSIONS: Despite complex microvascular tissue reconstructions, severe functional impairments remain and necessitate further investigations on improvement of postoperative speech, swallowing and chewing function.

[The leukemic child after therapy. Psychological aspects].

Thirty children in remission, at least one year after completing chemotherapy for Acute Lymphoblastic Leukemia, were assessed using general psychological measures. The Wechsler Intelligence tests were administered to evaluate their intellectual function: no significant reduction was found in overall IQ score. Only four of the patients, who presented neurological complications during the treatment, performed at lower levels. The group as a whole functioned poorly on tasks involving speeded performances and long-term memory. The age at diagnosis, the duration of the illness, the cranial irradiation and/or intrathecal-chemotherapy did not show any negative effects on the intellectual performance. Psycho-social adaptation was satisfactory: our patients do not show neurotic or psychotic disorders, but only affective disturbances (insecurity, irritability, poor self-perception, instability and depression). Familial adaptation was disturbed in 60% of the children and difficulty in socializing with peers was present in 57% of cases: the latter, in our experience, is related to poor self perception, present in 75% of our patients. We have found a more inadequate psycho-social adaptation in children who have not received any communication of their illness. Psychologic support can be of value for the child and his family in adapting to their difficult situation and in promoting a normal personality development of the child.

Predictability of hand skill and cognitive abilities from craniofacial width in right- and left-handed men and women: relation of skeletal structure to cerebral function.

Recently, a family of homeobox genes involved in brain and craniofacial development was identified. In light of this genetic background, we hypothesized that some functional characteristics of human brain (hand skill, cognition) may be linked to some structural characteristics of human skull (e.g., craniofacial width) in humans. Hand preference was assessed by Oldfield's Handedness Questionnaire. Hand skill was measured by Peg Moving Task. Face width was measured from the anteroposterior cephalograms (x-ray) using right (R) and left (L) zygomatic points. Intelligence "g" was assessed by Cattell's Culture Fair Intelligence Test; the perceptual-verbal ability was assessed by "Finding A's Test"; the spatial ability was assessed by the mental rotation task, in right- and left-handed men and women. The percentages of right-, left-, and mixed-faced subjects were close to those found for paw preference in cats. Women tended to be more right-faced (R--L > 0) and less left-faced (R--L < 0) than men, who tended to be more left-faced and less right-faced than women. R--L face width inversely correlated with L--R PMT (peg moving time) in left-handers; there was a direct relation between these variables in right-handers. Cattell IQ linearly increased with R--L face width in left-handers, negatively correlated in right-handed men and women. Verbal ability inversely related to R--L face width in right- and left-handed men, but directly correlated in right-handed women. The number of correct response on mental-rotation task positively and linearly correlated with R--L face width in left-handers and right-handed women. It was concluded that the structural-functional coupling revealed in the present work may have its origins in parallel development of the craniofacial skeleton and brain under the influence of homeobox genes.

Long-term outcome of Haemophilus influenzae meningitis in Navajo Indian children.

OBJECTIVES: To determine the long-term neurologic, cognitive, and educational outcomes of Navajo children who survived Haemophilus influenzae type b meningitis. DESIGN: Retrospective cohort study, with 3.6- to 15.0-year follow-up. SETTING: Navajo Indian reservation. PARTICIPANTS: Population-based cohort of 76 Navajo children with Haemophilus meningitis at less than 5 years of age between 1975 and 1986, with 41 (54%) consenting to undergo follow-up in 1990. Each case was matched to one nearest-age sibling and one unrelated age-matched control. MAIN OUTCOME MEASURES: Standard intelligence test scores, neurologic abnormalities, and school performance. RESULTS: The mean IQ for cases was lower than that for siblings (79 vs 87, P = .006) or age-matched controls (79 vs 95, P < .001). Twenty-nine percent of cases had severe neurologic sequelae, including mental retardation (24%), severe hearing loss (5%), cerebral palsy (7%), and seizure disorder (12%). Eight percent of siblings (relative risk for cases vs siblings, 8.0; P = .05) and 2% of age-matched controls (relative risk vs cases, 10.0; P = .01) had mental retardation. No siblings or age-matched controls had any other severe neurologic sequela. Twenty-nine percent of cases, 23% of siblings (relative risk, 2.5; P = .45), and 0% of age-matched controls (P = .001) required special education services, while 42% of cases, 23% of siblings (relative risk, 3.3; P = .10), and 11% of age-matched controls (relative risk, 4.0; P = .005) had been retained in a grade in school. CONCLUSIONS: Navajo survivors of Haemophilus meningitis suffer more long-term neurologic, cognitive, and school-related disability than siblings or age-matched controls. They may also suffer higher morbidity than Haemophilus meningitis survivors in the general population.

Evidence that dyslexia may represent the lower tail of a normal distribution of reading ability.

BACKGROUND: Dyslexia is now widely believed to be a biologically based disorder that is distinct from other, less specific reading problems. According to this view, reading ability is considered to follow a bimodal distribution, with dyslexia as the lower mode. We hypothesized that, instead, reading ability follows a normal distribution, with dyslexia at the lower end of the continuum. METHODS AND RESULTS: We used data from the Connecticut Longitudinal Study, a sample survey of 414 Connecticut children who entered kindergarten in 1983 and were followed as a longitudinal cohort. Dyslexia was defined in terms of a discrepancy score, which represents the difference between actual reading achievement and achievement predicted on the basis of measures of intelligence. Data were available from intelligence tests administered in grades 1, 3, and 5 and achievement tests administered yearly in grades 1 through 6. For each child there were 108 possible discrepancy scores ([3 x 3 years] x [2 x 6 years]) based on combinations of the ability scores (full-scale, verbal, and performance IQ) in each of three years and two achievement scores (reading and mathematics) in each of six years. We demonstrated that each of the discrepancy scores followed a univariate normal distribution and that the interrelation of two different discrepancy scores followed a bivariate normal distribution. At most, only 9 of 108 discrepancy scores (8.3 percent) and 171 of 3402 pairs of discrepancy scores (5.0 percent) were significantly different (at the 5 percent level) from the expected scores--well within the expected values for data with univariate and bivariate normal distributions, respectively. We also examined the stability of dyslexia over time. The normal-distribution model predicted (and the data indicated) that only 7 of the 25 children (28 percent) classified as having dyslexia in grade 1 would also be classified as having dyslexia in grade 3. CONCLUSIONS: Reading difficulties, including dyslexia, occur as part of a continuum that also includes normal reading ability. Dyslexia is not an all-or-none phenomenon, but like hypertension, occurs in degrees. The variability inherent in the diagnosis of dyslexia can be both quantified and predicted with use of the normal-distribution model.

[Effects of touch on growth and mentality development in normal infants].

OBJECTIVE: To determine the effects of conducting Touch to infants upon their growth and mental development, sleeping and disease conditions, as well as the difference of effects of conducting Touch among infants of different month age. METHODS: 310 normal full-term infants aged 0-6 months were divided randomly into Touch group (n = 208) and control group (n = 102). Parents of Touch group were asked to conduct Touch to their infants 2-3 times/day, lasting 15-20 minutes every time, for at least 3 months. Intelligence tests were performed to infants of both groups at the beginning of the experiment and 6 months later (CDCC measurement table was employed). Data such as height, weight, circumferences of head and chest, sleeping, feeding and disease conditions etc. were recorded each month in a successive period of 6 months. Statistical analysis was conducted using SPSS 10.0. RESULTS: (1) The average score of mental development (MDI) was 7.4 higher, with a statistically significant difference, among the infants who began to receive touch within 3 months after birth than those infants with the same age in control group. The average score of psychomotor development index (PDI) was 5.8 higher, with a statistically significant difference, among the infants who began to receive touch within 3 months after birth than those infants with the same age in control group. Infants who began to receive touch within 3 months after birth slept remarkably better than those in control group did. No significant difference was found in scores of MDI and PDI and sleeping condition between infants who began to receive touch 3 months after birth and the infants with the same age in the control group. (2) Weight gain and growth in chest circumference in infants receiving touch within one month after birth were significantly better compared with the infants of the same age in the control group. There was no significant difference in values of height and head circumference between the two groups. There was no significant difference in values of height and head circumference between the two groups. (3) No significant difference in the incidence rates of acute respiratory infection and diarrhea disease was found between the touch group and control group. CONCLUSION: (1) Growth and mental development of infants can be improved by touch. Tthe earlier to conduct touch the better the effects. (2) Touch helps improve sleeping condition in infants.

The inverse relationship between nonverbal intelligence and the latency of the Hoffmann reflex from the right and left thenar muscles in right- and left-handed subjects.

The relationship between nonverbal reasoning ability and the latency of the Hoffmann (H) reflex was studied in right- and left-handed subjects. The nonverbal reasoning ability was assessed by the Cattell's Culture Fair Intelligence test. Hand preference was assessed by the Edinburgh Handedness Inventory. Hoffmann reflex was recorded from thenar muscles of the right and left thumbs. In left-handers (total sample), IQ was found to be significantly and negatively linearly related to the H-reflex latency from the left side. In strong left-handers, there was a significant negative linear relationship between IQ and the H-reflex latency from right and left sides, but with a higher correlation for the left side. In weak left-handers, IQ did not show any significant relation to the H-reflex latencies from the right and left sides. In right-handers (total sample), there was a significant negative linear correlation between IQ and the H-reflex latency from the right side. In right-handed women without familial sinistrality (FS-), IQ was found to be inversely related to the H-reflex latency from the right and left side, but with a higher correlation for the right side. In right-handed women with FS, IQ did not show any significant relation to the H-reflex latency from the right and left sides. In right-handed men with right eye preference and FS-, IQ was found to be negatively linearly related to the H-reflex latency from the right and left sides equally. In right-handed men with right eye FS+, mixed eye FS-, +, mixed eye-right foot (FS-), mixed eye-mixed foot, and left eye preference there was no significant relationship between IQ and the H-reflex latency from the right and left sides. Only in strong left-handers there was a significant, positive linear correlation between IQ and the right minus left (R-L) difference of latencies. The H-reflex latency from the right and left sides was not significantly correlated with the R-L difference of latencies in left-handers. In right-handed women with right eye preference FS-, and in right-handed men with right eye preferences FS-, The H-reflex latency from the right side was found to be positively linearly correlated with the R-L difference of latencies. In right-handed women FS+, and in right-handed men FS+, and mixed or left eye preference, the H-reflex latency from the left side was found to be negatively linearly related to the R-L difference of latencies.(ABSTRACT TRUNCATED AT 400 WORDS)

Carbamazepine and phenytoin. Comparison of cognitive effects in epileptic patients during monotherapy and withdrawal.

We compared the cognitive effects of carbamazepine and phenytoin with neuropsychological tests exploring intelligence, vigilance, attention, memory, and visuomotor performances in 25 epileptics (13 receiving carbamazepine and 12 receiving phenytoin) and 26 matched normal controls. Patients were seizure free for at least two years and taking prolonged monotherapy. We also evaluated the effects of drug withdrawal by retesting patients three months after reduction at half drug dose and three months and one year after complete withdrawal. Our findings suggest that phenytoin affects the cognitive functions more than carbamazepine does, although the negative effects of both drugs are reversible by complete therapy withdrawal.

WISC scatter and behavioral competence in high-risk children.

Examined the relationship between WISC scatter and school competence measures for 101 boys at risk for psychiatric disorder. This sample, shown in previous research to be less competent in school than controls, was predicted to have greater scatter than a standardization sample. Further, within the high-risk sample, an association was predicted between two measures of scatter and lowered school competence, as measured by Fisher's (1980) peer and teacher ratings. The results suggested that the mean scatter variable available for both samples is significantly higher in the high-risk group than in the intelligence test standardization sample. This scatter measure also measures. The second measure did not relate significantly to any of the school measures. These findings suggest that one of the two scatter measures is a valid index of less competent school functioning and may be in combination with other measures, a useful predictor of future psychopathology.
