Impact of unilateral spatial neglect on chronic patient's post-stroke quality of life.

BACKGROUND: Unilateral spatial neglect (USN) is the prevalent feature in patients with right-sided stroke. It is diagnosed through the behavior inattention test (BIT) and has a negative impact on patients affecting both their functional capacity and quality of life. OBJECTIVE: Here, we aimed to evaluate the impact of USN on the quality of life of patients in the chronic phase of stroke. METHODS: This is a cross-sectional study with stroke patients with USN. After confirming the presence of stroke through neuroimaging examinations and of USN through the BIT, patients' quality of life was evaluated by using the EUROQOL scale. Spearman's correlation was used to validate the correlation between patients' USN and quality of life, with a p < .05 representing significant results. RESULTS: Eighteen individuals were included. When correlating the value of each domain of the EUROQOL scale with the results of the BIT, we observed a negative correlation between mobility (r = -0.97; p = .000), self-care (r = -0.82; p = .013), usual activities (r = -0.87; p = .005); pain or discomfort (r = -0.88; p = .004), anxiety or depression (r = -0.97; p = .000), and EUROQOL total score (r = -0.97, p = .000). CONCLUSION: After a correlation between the overall EUROQOL and BIT scores, we suggest that the higher the USN degree is in stroke patients, the worse their perceived quality of life tends to be.

Standardization of the face-hand test in a Brazilian multicultural population: prevalence of sensory extinction and implications for neurological diagnosis

OBJECTIVE: The face-hand test is a simple, practical, and rapid test to detect neurological syndromes. However, it has not previously been assessed in a Brazilian sample; therefore, the objective of the present study was to standardize the face-hand test for use in the multi-cultural population of Brazil and identify the sociodemographic factors affecting the results. METHODS: This was a cross sectional study of 150 individuals. The sociodemographic variables that were collected included age, gender, race, body mass index and years of education. Standardization of the face-hand test occurred in 2 rounds of 10 sensory stimuli, with the participant seated to support the trunk and their vision obstructed in a sound-controlled environment. The face-hand test was conducted by applying 2 rounds of 10 sensory stimuli that were applied to the face and hand simultaneously. The associations between the face-hand test and sociodemographic variables were analyzed using Mann-Whitney tests and Spearman correlations. Binomial models were adjusted for the number of face-hand test variations, and ROC curves evaluated sensitivity and specificity of sensory extinction. RESULTS: There was no significant relationship between the sociodemographic variables and the number of stimuli perceived for the face-hand test. There was a high relative frequency of detection, 8 out of 10 stimuli, in this population. Sensory extinction was 25.3%, which increased with increasing age (OR=1.4[1:01–1:07]; p=0.006) and decreased significantly with increasing education (OR=0.82[0.71-0.94]; p=0.005). CONCLUSION: In the Brazilian population, a normal face-hand test score ranges between 8–10 stimuli, and the results indicate that sensory extinction is associated with increased age and lower levels of education.

Writing to dictation and handwriting performance among Chinese children with dyslexia: relationships with orthographic knowledge and perceptual-motor skills.

The purpose of this study was to investigate the relationships between writing to dictation, handwriting, orthographic, and perceptual-motor skills among Chinese children with dyslexia. A cross-sectional design was used. A total of 45 third graders with dyslexia were assessed. Results of stepwise multiple regression models showed that Chinese character naming was the only predictor associated with word dictation (ß=.32); handwriting speed was related to deficits in rapid automatic naming (ß=-.36) and saccadic efficiency (ß=-.29), and visual-motor integration predicted both of the number of characters exceeded grid (ß=-.41) and variability of character size (ß=-.38). The findings provided support to a multi-stage working memory model of writing for explaining the possible underlying mechanism of writing to dictation and handwriting difficulties.

Association of trauma-related disorders and dissociation with four idioms of distress among Latino psychiatric outpatients.

Past research on idioms of distress among U.S. Latinos has revealed that ataque de nervios and altered perceptions, such as hearing and seeing things when alone, are independent markers of higher morbidity and mental health utilization despite having no one-to-one relationships with any single psychiatric diagnosis. It has been proposed that the idioms exert this effect because they are signs of distressing dissociative capacity associated with traumatic exposure. This study examines the relationships in an ethnically diverse Latino psychiatric outpatient sample (N = 230) among interpersonal trauma, posttraumatic stress disorder (PTSD), major depressive disorder, dissociative capacity and four cultural idioms of distress associated with the popular overall category of nervios. We particularly explore how these relationships change with varied measures of traumatic exposure, including trauma severity and timing or persistence of trauma. A series of adjusted bivariate regressions assessed the matrix of associations between the idioms and the clinical variables. In this highly traumatized population, we identified a strong 'nexus' of associations between dissociation and three of the idioms: currently being ill with nerves, ataque de nervios and altered perceptions. These idioms were largely independent from PTSD and depression and were associated with trauma persistence and severity. A fourth idiom, being nervous since childhood, was not associated with any other variable and may represent a personality trait rather than a diagnosable condition. Our results validate the clinical utility of the construct of nervios as a set of specific idioms associated with dissociation that are useful markers of mental health need among Latinos independently of their association with clinical diagnoses.

The McGurk phenomenon in Italian listeners.

In the classic example of the McGurk effect, when subjects see a speaker say /ga/ and hear a simultaneous /ba/, they typically perceive /da/, a syllable that was not presented either acoustically, or visually. This phenomenon, although non-natural and recreated in laboratory investigations, has been studied in order to better understand how, where and when the central nervous system processes and integrates visual and auditory signals. Till now, it has been demonstrated for English, Spanish and German languages, while in Japanese and Chinese it seems weaker. Aim of this study was to evaluate the entity of the McGurk effect for the Italian language. Results obtained demonstrate a robust McGurk effect for the Italian language, which has never been described before. The phenomenon is highly significant when an auditory bilabial Consonant-Vowel is dubbed with a visual apico-dental or velar Consonant-Vowel. Results are discussed on the basis of the recent hypothesis regarding the bimodal perception.

Body Dysmorphic Disorder: gender differences and prevalence in a Pakistani medical student population.

BACKGROUND: Body dysmorphic disorder (BDD) is a psychiatric disorder characterized by a preoccupation with an imagined or slight defect which causes significant distress or impairment in functioning. Few studies have assessed gender differences in BDD in a non clinical population. Also no study assessed BDD in medical students. This study was designed to determine the point prevalence of BDD in Pakistani medical students and the gender differences in prevalence of BDD, body foci of concern and symptoms of BDD. METHODS: The medical students enrolled in a medical university in Karachi, Pakistan filled out a self-report questionnaire which assessed clinical features of BDD. BDD was diagnosed according to the DSM-IV criteria. RESULTS: Out of the 156 students, 57.1% were female. A total of 78.8% of the students reported dissatisfaction with some aspect of their appearance and 5.8% met the DSM-IV criteria for BDD. The male to female ratio for BDD was 1.7. Regarding gender differences in body foci of concern, the top three reported foci of concern in male students were head hair (34.3%), being fat (32.8%), skin (14.9%) and nose(14.9%), whereas in females they were being fat (40.4%), skin (24.7%) and teeth (18%). Females were significantly more concerned about being fat (p = 0.005). Male students were significantly more concerned about being thin (p = 0.01) and about head hair (p = 0.012). CONCLUSION: BDD is fairly common in our medical student population, with a higher prevalence in males. Important gender differences in BDD symptomatology and reported body foci of concern were identified which reflected the influence of media on body image perception. The impact of cultural factors on the prevalence as well as gender differences in BDD symptomatology was also established.

Scale for assessing perceptual anomalies. Validation of a Spanish version of the SIAPA scale in a sample of Cuban schizophrenic patients.

INTRODUCTION: Perceptual-attentional disorders other than hallucinations in schizophrenic patients have been studied little. In this work, the results of the Spanish version of the SIAPA scale to detect perceptual-attentional anomalies to real stimuli other than hallucinations in a sample of schizophrenic patients in a community study in Cuba are presented. METHODS: 329 subjects were studied: 129 schizophrenic patients and 200 controls. Patients were diagnosed by psychiatrists according to DSM-IV criteria. The SIAPA and PANSS scales were used for the study. Cronbach's alpha coefficient was determined to analyze internal consistency. Reliability, validity of current criterion and structural validity were measured. Comparisons between groups were made using the ANOVA. RESULTS: Schizophrenic patients had more perceptual anomalies than healthy controls. Auditory and visual perceptual anomalies were more frequent. The scale showed high internal consistency (Cronbach's alpha: 0.84). Using a PANSS scale cut-off score of 60, validity had a sensitivity of 56 % and specificity of 79 %. All modalities of SIAPA scales showed good kappa coefficients (0.72-0.85). CONCLUSIONS: This scale showed similar internal validity and test-retest reliability to those reported in the English version. The results showed that this scale can differentiate the presence of perceptual anomalies in schizophrenic patients from healthy controls. Therefore, we suggest that the SIAPA scale may be useful for assessing perceptual anomalies in clinical researching for cognitive impairment evaluations.

Emotional face processing deficit in schizophrenia: A replication study in a South African Xhosa population.

Schizophrenia is associated with a deficit in the recognition of negative emotions from facial expressions. The present study examined the universality of this finding by studying facial expression recognition in African Xhosa population. Forty-four Xhosa patients with schizophrenia and forty healthy controls were tested with a computerized task requiring rapid perceptual discrimination of matched positive (i.e. happy), negative (i.e. angry), and neutral faces. Patients were equally accurate as controls in recognizing happy faces but showed a marked impairment in recognition of angry faces. The impairment was particularly pronounced for high-intensity (open-mouth) angry faces. Patients also exhibited more false happy and angry responses to neutral faces than controls. No correlation between level of education or illness duration and emotion recognition was found but the deficit in the recognition of negative emotions was more pronounced in familial compared to non-familial cases of schizophrenia. These findings suggest that the deficit in the recognition of negative facial expressions may constitute a universal neurocognitive marker of schizophrenia.

Working memory in Dutch children with reading- and arithmetic-related LD.

The aim of the two studies presented in this article was to examine working memory performance in Dutch children with various subtypes of learning disabilities. The performance of children with reading disabilities (RD) was compared to that of children with arithmetic disabilities (AD), children with both reading and arithmetic disabilities (RAD), and chronological age-matched controls (CA). Measures covered the phonological loop, the visuospatial sketchpad, and the central executive. In both studies, the children with RD showed no working memory deficits whatsoever. Children with AD showed a single impairment on the task tapping working memory for dynamic visual information. Children with RAD performed lower only on the digit span backward task. The failure to replicate the expected working memory deficits in children with reading-related disabilities is discussed.

The cognitive profile and multiple-deficit hypothesis in Chinese developmental dyslexia.

The present study was conducted to examine the cognitive profile and multiple-deficit hypothesis in Chinese developmental dyslexia. Thirty Chinese dyslexic children in Hong Kong were compared with 30 average readers of the same chronological age (CA controls) and 30 average readers of the same reading level (RL controls) in a number of rapid naming, visual, phonological, and orthographic tasks. Chinese dyslexic children performed significantly worse than the CA controls but similarly to the RL controls on most of the cognitive tasks. The rapid naming deficit was found to be the most dominant type of cognitive deficit in Chinese dyslexic children. Over half of the dyslexic children exhibited deficits in 3 or more cognitive areas, and there was a significant association between the number of cognitive deficits and the degree of reading and spelling impairment. The present findings support the multiple-deficit hypothesis in Chinese developmental dyslexia.
