Social cognition in epilepsy
Some of the psychological problems associated with epilepsy have their origins in the ability of people with epilepsy (PWE) to engage in meaningful and appropriate social interactions. PWE often report difficulties in social settings, yet there is a paucity of research investigating the socio-cognitive skills of this group. This thesis aimed to investigate these skills and relate them to the patient's perceived impact of epilepsy on their social competence. An additional objective was to see whether studying social cognition in focal epilepsy might provide some insight into the organic basis of social cognitive abilities in the normal population. The thesis consists of four separate studies which aimed to investigate social cognition and social functioning in patients with focal epilepsy. With this in mind, a test battery assessing a range of skills linked to social cognition was administered to a cross section of experimental groups (N=95). These included patients with seizure foci in the right frontal lobe (RF), left frontal lobe (LF), right temporal lobe (RT), left temporal lobe (LT) and a group with idiopathic generalised epilepsy (IGE). A normal control group (NC) and a frontal head injured (FHI) group with no epilepsy were also recruited for the study. In Studies 1 and 2 theory of mind (ToM) deficits were apparent in people with RF and LT epilepsy. These groups demonstrated impairment in the appreciation of false belief and deception at first and second order levels of intentionality. They also exhibited deficits in the appreciation of pragmatic language when attempting to infer the meaning underlying hints given by story characters. These impairments were in part attributable to deficits in narrative memory in the LT group. In Study 3 embedding problems within a social context significantly facilitated conditional reasoning in the NC, LT and RF groups but not in the other experimental groups. This finding was unexpected and suggests a double dissociation between ToM and social conditional reasoning. Study 4 investigated the extent to which socio-cognitive impairment was associated with the perceived impact of epilepsy on everyday social functioning. No statistically significant relationship between these variables was found, although a significant negative correlation between education level and impact of epilepsy was observed. Taken together the findings suggest that impairment in ToM may be a particular feature of right frontal lobe pathology and that social conditional reasoning and ToM may be functionally dissociated. PWE do not appear to have insight into their social functioning difficulties, which may well reflect underlying pathology. In light of this, future research should obtain objective measures of social competence from `significant others'. This is the only series of studies to date to assess social cognition in people with frontal lobe epilepsy (FLE) and temporal lobe epilepsy (TLE) within the same design. It is also the first time that social conditional reasoning in epilepsy has been systematically assessed and represents one of the largest lesion studies within the field of social cognition. It is hoped that some of the test material used in the thesis, may prove to be a useful and inexpensive clinical resource to help identify PWE who are at risk of reduced social competence, and in localising the site of seizure foci in patients during clinical audit, particularly where anterior foci are suspected
Illness Perception Mediates the Relationship Between the Severity of Symptoms and Perceived Health Status in Patients With Behçet Disease
Objective: The aim of this study was to investigate the relationship between psychological representations of illness, perceived health status, and self-assessment of symptom severity in patients with Behçet disease, a rare long-term incurable condition with unclear etiology. Methods: Using cross-sectional survey design, data on self-administered questionnaires on illness perception, health status, symptoms severity, and demographic characteristics were collected from 273 patients with Behçet disease (age range, 18–65 years). The data were subjected to mediation analysis to test whether cognitive and emotional components of illness perception mediate the relationship between the severity of symptoms and heath status. Results: The results support our hypotheses that cognitive components of illness perception (perceived consequences and identity of the illness) mediate the link between symptom activity and pain, whereas emotional components of the illness (emotional representations about the illness) mediate the relationship between disease activity and perceived energy level. Conclusions: The robustness of these mediation effects suggests potential directions for clinical psychologists and health care practitioners in developing support programs. We supplement our study with Open Access database containing information about type ofmedication, comorbidmood disorder, and detailed measurement of the severity of BD symptoms for sharing and accumulating multidisciplinary knowledge aiming to support the development of interventions. Addressing psychological aspects of BD will help to manage complex patients effectively
Fluid Intelligence and Psychosocial Outcome: From Logical Problem Solving to Social Adaptation
While fluid intelligence has proved to be central to executive functioning, logical reasoning and other frontal functions, the role of this ability in psychosocial adaptation has not been well characterized.Lower fluid intelligence scores were associated with physical violence, both in the role of victim and victimizer. Drug intake, especially cannabis, cocaine and inhalants and lower self-esteem were also associated with lower fluid intelligence. Finally, scores on the perceived mental health assessment were better when fluid intelligence scores were higher.Our results show evidence of a strong association between psychosocial adaptation and fluid intelligence, suggesting that the latter is not only central to executive functioning but also forms part of a more general capacity for adaptation to social contexts

Early predictors of outcome in newly diagnosed epilepsy
Longitudinal studies of newly diagnosed epilepsy in children and adults have identified prognostic factors that allow early identification of patients whose seizures are likely to remain uncontrolled with antiepileptic medication. Results from outcome studies may be subject to bias, depending on the setting (community versus clinic), design (retrospective versus prospective) and characteristics of the patient cohort studied (age, types of epilepsy, specific comorbidities). Nevertheless, factors such as early response to medication, underlying aetiology, and number of seizures prior to initiation of treatment have consistently been found to be predictive of seizure outcomes. Other variables such as age, electroencephalographic findings and the presence or absence of psychiatric co-morbidities have been correlated with outcomes in some analyses. This review has examined studies of seizure outcomes in adults and children with newly diagnosed epilepsy identifying the risk factors that are associated with subsequent refractory epilepsy
