Assessment of psychosocial adjustment in patients with temporal lobe epilepsy using a standard measure

Despite the growing evidence of poor psychosocial adjustment, at present there is no formal method of assessment of social adjustment in patients with temporal lobe epilepsy (TLE). First, we assessed social adjustment in patients with TLE using a self-report questionnaire and compared the results with those from quality-of-life (QOL) scales. Second, we verified the influence of cognitive performance and clinical variables of epilepsy on social adjustment and QOL We evaluated 35 people with TLE and 38 healthy controls. Patients had worse social adjustment, and it was correlated with worse perception of cognitive function. Attention and verbal memory dysfunctions were negatively correlated with social adjustment. However, there was no significant correlation between cognitive performance and QOL Regarding clinical variables, persons with left TLE showed worse social adjustment and patients with frequent seizures showed worse QOL These findings indicate the relevance of evaluating social adjustment and emphasize the importance of cognitive rehabilitation to improved social adjustment.

Personality traits in patients with juvenile myoclonic epilepsy

There is evidence of personality disorders in patients with juvenile myoclonic epilepsy (JME). To date, there have been no published quantitative studies on personality traits in JME. The aim of the work described here was to study a group of patients with JME and quantitatively measure personality traits. We evaluated 42 patients (mean age: 26.57 years, SD: 8.38) and 42 controls (mean age: 26.96, SD: 8.48) using a validated personality inventory, the Temperament and Character Inventory (TCI). We applied two scores, one for the Beck Depression Inventory and one for the State-Trait-Anxiety Inventory, as depression and anxiety may impact the performance of these patients on the TCI. We compared both groups on TCI scales using analysis of covariance with Beck Depression Inventory and State-Trait-Anxiety Inventory scores as covariates. Patients with JME obtained significantly higher scores on Novelty Seeking (P=0.001) and Harm Avoidance (P=0.002) and significantly lower scores on Self-Directedness (P=0.001). Patients with JME have a higher expression of impulsive personality traits that demand early recognition to avoid further consequences and facilitate social insertion, consequently avoiding future stigma.

Time course of haemodynamic, respiratory and inflammatory disturbances induced by experimental acute pulmonary polystyrene microembolism

Background and objective The time course of cardiopulmonary alterations after pulmonary embolism has not been clearly demonstrated and nor has the role of systemic inflammation on the pathogenesis of the disease. This study aimed to evaluate over 12 h the effects of pulmonary embolism caused by polystyrene microspheres on the haemodynamics, lung mechanics and gas exchange and on interleukin-6 production. Methods Ten large white pigs (weight 35-42 kg) had arterial and pulmonary catheters inserted and pulmonary embolism was induced in five pigs by injection of polystyrene microspheres (diameter similar to 300 mu mol l(-1)) until a value of pulmonary mean arterial pressure of twice the baseline was obtained. Five other animals received only saline. Haemodynamic and respiratory data and pressure-volume curves of the respiratory system were collected. A bronchoscopy was performed before and 12 h after embolism, when the animals were euthanized. Results The embolism group developed hypoxaemia that was not corrected with high oxygen fractions, as well as higher values of dead space, airway resistance and lower respiratory compliance levels. Acute haemodynamic alterations included pulmonary arterial hypertension with preserved systemic arterial pressure and cardiac index. These derangements persisted until the end of the experiments. The plasma interleukin-6 concentrations were similar in both groups; however, an increase in core temperature and a nonsignificant higher concentration of bronchoalveolar lavage proteins were found in the embolism group. Conclusion Acute pulmonary embolism induced by polystyrene microspheres in pigs produces a 12-h lasting hypoxaemia and a high dead space associated with high airway resistance and low compliance. There were no plasma systemic markers of inflammation, but a higher central temperature and a trend towards higher bronchoalveolar lavage proteins were found.

Neuropsychological Outcome of Ventral Capsular/Ventral Striatal Gamma Capsulotomy for Refractory Obsessive-Compulsive Disorder: A Pilot Study

Five refractory obsessive-compulsive patients were assessed using a neuropsychological battery after a modified gamma knife capsulotomy. The surgical technique was not associated with profound cognitive deficits. The authors found improvements in attention, vocabulary, learning, abstract reasoning, and memory.

Executive dysfunction in children and adolescents with temporal lobe epilepsy: Is the Wisconsin Card Sorting Test enough?

The Wisconsin Card Sorting Test (WCST) is the gold standard in the evaluation of executive dysfunction (ED) in patients with temporal lobe epilepsy (TLE). We evaluated 35 children with TLE and 25 healthy controls with the WCST and with a more comprehensive battery. Among the children with TLE, 77.14% showed impairment on the WCST. On other tests (Wechsler Intelligence Scale for Children-Digit Forward, Matching Familiar Figures Test, Trail Making Test, Word Fluency, Finger Windows, and Number-Letter Memory), impairment was demonstrated in 94.29%. The authors concluded that the WCST is a good paradigm to measure executive impairment in children with TLE: however, it may be not enough. Evaluation performed only with the WCST not only underestimated the number of patients with ED, but also missed relevant information regarding the type of ED. (C) 2009 Elsevier Inc.

Suicide behavior and neuropsychological assessment of type I bipolar patients

Background: Neuropsychological deficits are often described in patients with bipolar disorder (BID). Some symptoms and/or associated characteristics of BD can be more closely associated to those cognitive impairments. We aimed to explore cognitive neuropsychological characteristics of type I bipolar patients (BPI) in terms Of lifetime Suicide attempt history. Method: We studied 39 BPI Outpatients compared with 53 healthy controls (HC) matched by age, educational and intellectual level. All Subjects were submitted to a neuropsychological assessment of executive functions, decision-making and declarative episodic memory. Results: When comparing BD1 patients, regardless of suicide attempt history or HC, we observed that bipolar patients performed worse than controls oil measures of memory, attention, executive functions and decision-making, Patients with a history of suicide attempt performed worse than non-attempters on measures of decision-making and there were a significant negative correlation between the number of suicide attempts and decision-making results (block 3 and net score). We also found significant Positive correlation between the number Of Suicide attempts and amount Of errors in Stroop Color Word Test (part 3). Limitations: The sample Studied call be considered small and a potentially confounding variable - medication status - were not controlled. Conclusion: Our results show the presence of neuropsychological deficits in memory, executive functions, attention and decision-making in BPI patients. Suicide attempts BPI scored worse than non-suicide attempt Bill oil measures of decision-making. More suicide attempts were associated with a worse decision-making process. Future research should explore the relationship between the association between this specific cognitive deficits in BPIs, serotonergic function and suicide behavior in bipolar patients as well other diagnostic groups.
