Executive functioning and depressed mood before and after unilateral frontal lobe resection for intractable epilepsy.

Executive dysfunction occurs in a variety of patients who have sustained damage to the frontal lobes. In individuals with frontal lobe epilepsy (FLE) or after unilateral frontal lobe resection (FLR), a unique neuropsychological profile linking executive functions (EF) with the frontal lobe has been elusive, with conflicting findings in the literature. Some studies show greater risk of executive impairment with left-sided FLE or FLR, while others report greater risk for right-sided patients. Some studies report no relationship between FLE and EF impairment, while others show EF impairment regardless of side of seizure foci or surgery. In patients with temporal lobe epilepsy, executive dysfunction is associated with depressed mood possibly reflecting disruption of cortical-limbic pathways and/or frontal-striatal circuitry. Although not previously examined, depression level may affect executive functioning in those with FLE or FLR. We hypothesized that FLE patients with poor mood state would show greater executive dysfunction than FLE patients without poor mood state. The relationship among EF, side of surgery and depressed mood before and 8 months after unilateral FLR was evaluated in 64 patients using validated measures of EF and mood state (Beck Depression Inventory-II). Results indicated that individuals with depressed mood before surgery had greater difficulty on a task of mental flexibility compared to patients without preoperative depressed mood. Further, individuals with depressed mood before surgery had significant increases in perseverative responding and completed fewer categories on a card-sorting task after surgery compared to patients without preoperative depressed mood. Regression analyses showed that among side of surgery, seizure freedom status after surgery and depression status, only pre-surgical depression status explained a significant amount of variance in executive functioning performance after surgery. Results suggest that clinically elevated depressive symptoms before surgery are a risk factor for moderate declines in EF after surgery. Results may be attributable to reduced cognitive reserve in patients with depressive symptoms, or may reflect a common cause attributable to damage to unilateral dorsal and ventral lateral frontal lobe.

Prediction of neuropsychological outcome after resection of temporal and extratemporal seizure foci.

Resection of seizure foci is an effective treatment for the control of medically intractable epilepsy. However, cognitive morbidity can occur as a result of surgical intervention. This morbidity is dependent on several factors, including location and extent of resection, disease characteristics, patient demographic characteristics, and functional status of the tissue to be resected. In this review article, the authors provide a summary of the neurocognitive outcomes of epilepsy surgery with an emphasis on presurgical predictors of postsurgical cognitive decline.

Pre-surgical mood predicts memory decline after anterior temporal lobe resection for epilepsy.

This study examined pre-surgical depressed mood as a predictor of post-surgical memory change in adults who underwent temporal lobe resections (TLRs; n = 211). Patients completed the Wechsler Memory Scale-III and Beck Depression Inventory-Second Edition (BDI-II) before and after TLR (left = 110, right = 101) and were divided into two groups (clinically elevated depressive symptoms or not depressed) based on BDI-II score. Left-TLR patients with poorer pre-surgical mood had greater verbal memory declines after surgery compared with nondepressed left- or right-TLR patients and right-TLR patients with poor mood. Further, pre-surgical BDI-II score demonstrated incremental validity in predicting post-surgical memory change in left-TLR patients beyond pre-surgical memory scores. Differences in seizure outcome and post-surgical mood change could not account for memory decline. Results suggest that elevated pre-surgical depressive symptomatology is a risk factor for post-surgical memory decline and indicate that mood should be considered when advising patients about cognitive risks associated with temporal lobectomy. Results are discussed in terms of poor pre-surgical mood as an indicator of reduced cognitive reserve.

Self-blame, self-forgiveness, and spirituality in breast cancer survivors in a public sector setting.

Cognitive appraisal affects adjustment to breast cancer. A self-forgiving attitude and spirituality may benefit breast cancer survivors who blame themselves for their cancer. One hundred and eight women with early breast cancers completed questionnaires assessing self-blame, self-forgiveness, spirituality, mood and quality of life (QoL) in an outpatient breast clinic. Women who blamed themselves reported more mood disturbance (p < 0.01) and poorer QoL (p < 0.01). Women who were more self-forgiving and more spiritual reported less mood disturbance and better QoL (p's < 0.01). Interventions that reduce self-blame and facilitate self-forgiveness and spirituality could promote better adjustment to breast cancer.

Changes in individual and group spatial and verbal learning characteristics after anterior temporal lobectomy.

PURPOSE: To evaluate the effects of anterior temporal lobectomy (ATL) on individual and group spatial and verbal learning and memory abilities as a function of side of surgery and seizure control outcome. METHODS: We evaluated pre- and postsurgical learning and memory abilities of 75 left-hemisphere language dominant individuals who underwent ATL (33 left, 42 right) using the 8-trial Nonverbal Selective Reminding test and the 12-trial Verbal Selective Reminding test. RESULTS: Reliable change index methods indicated that 40.5% of individuals who underwent right-ATL had a clinically significant decline in spatial memory, and 62.5% of individuals who underwent left-ATL had a significant reduction in verbal memory. Growth curve analyses indicated that both side of surgery and poor seizure outcome independently affected the learning slope in the best fitting models. Left-ATL reduced the slope, but did not affect the overall shape, of verbal learning across trials. On the other hand, poor seizure control outcome affected the slope of spatial learning regardless of the side of surgery. DISCUSSION: Results demonstrate both individual and group declines in spatial memory and learning after ATL. Results suggest that individuals who undergo right-ATL should be counseled regarding the likelihood of a decline in spatial memory and learning abilities after ATL. Results also suggest that individuals with poor seizure control after ATL should be referred for rehabilitation services given the significant declines in spatial and verbal memory that occurred in our sample regardless of side of surgery.

Depressed mood and memory impairment before and after unilateral posteroventral pallidotomy in Parkinson's disease.

This study evaluated poor mood state as a moderator of changes in verbal recall ability from before to after unilateral posteroventral pallidotomy in 54 individuals with advanced Parkinson's disease. Repeated-measures analysis of covariance (controlling for motor disease severity) indicated that left-posteroventral pallidotomy subjects with depressed mood performed more poorly on measures of verbal list learning and story recall compared to nondepressed subjects or right-posteroventral pallidotomy subjects with depressed mood both before and after surgery. The results suggest that depressed mood should be taken into account when interpreting memory test performance in Parkinson's disease surgical candidates both before and after surgery.

Attribution of blame, self-forgiving attitude and psychological adjustment in women with breast cancer.

The purpose of this study was to examine relationships among self-blame for developing breast cancer, a self-forgiving attitude, mood, and quality of life among women with breast cancer. In this cross-sectional study, 123 women with Stages 0-III breast cancer completed questionnaires measuring demographic and medical characteristics, self-blame, self-forgiveness, mood, and quality of life. Women who blamed themselves reported more mood disturbance (p

Memory, emotional and vocational impairments before and after anterior temporal lobectomy for complex partial seizures.

PURPOSE: To assess the pre- and postsurgical frequency of memory, emotional, and vocational impairments in patients who underwent anterior temporal lobectomy (ATL), and to assess the relationship between emotional disturbance and memory abilities after ATL. METHODS: Retrospective analysis of data was performed on 90 patients with medically intractable complex partial seizures who underwent ATL between 1981 and 2003. Patients were evaluated an average of 5 months before surgery and 11.3 months after surgery. RESULTS: A moderate to high frequency of memory impairment (44.4%; verbal or nonverbal), emotional disturbance (38.9%) and unemployment (27.8%) existed in the same individuals both before and after surgery. There were small to moderate rates of new onset memory (18.9%), emotional (11.1%), and vocational (7.8%) difficulties after surgery often regardless of seizure control outcome. Patients who underwent left-ATL and had emotional disturbance after surgery had the lowest verbal memory test scores. CONCLUSIONS: Results highlight the importance of taking into account emotional status when assessing memory abilities after ATL. Results replicate the finding of moderate to high frequencies of memory impairment, emotional disturbance, and unemployment both before and after ATL. Results provide support for the rationale that cognitive, psychiatric and vocational interventions are indicated to mitigate the problems that exist before and persist after ATL.

Medical and psychosocial predictors of delay in seeking medical consultation for breast symptoms in women in a public sector setting.

We examined demographic, medical and psychosocial factors related to delay in seeking medical consultation for breast symptoms. In this cross-sectional survey, 124 women with breast symptoms attending an outpatient breast surgery clinic in a county general hospital completed questionnaires measuring demographic, medical and psychosocial variables. Our outcome variable was delay in seeking medical consultation. Younger age (p

Characterization of the sniff magnitude test.

OBJECTIVE: To evaluate the potential utility of the Sniff Magnitude Test (SMT) as a clinical measure of olfactory function. DESIGN: Between-subject designs were used to compare the SMT and University of Pennsylvania Smell Identification Test (UPSIT) in study participants from a broad range of ages. SUBJECTS: A total of 361 individuals from retirement communities and an urban university and patients from an otolaryngology clinic. INTERVENTION: Study participants completed the SMT and UPSIT using standard procedures. MAIN OUTCOME MEASURES: The UPSIT was scored using standard procedures to calculate the number of correctly identified odors; a score that can range from 0 to 40 correct. The measure of olfactory function generated by the SMT is the "sniff magnitude ratio," defined as the mean sniff magnitude generated by the odor stimuli divided by the mean sniff magnitude to nonodorized air blanks. RESULTS: The SMT generally showed good agreement with UPSIT diagnostic categories, although SMT scores were only modestly elevated in the mild and modest hyposmia range of the UPSIT. Age-related decline in olfactory ability was evident on the UPSIT at younger ages than that seen with the SMT. As predicted, otolaryngology patients with olfactory complaints were found to be impaired on both the UPSIT and SMT. CONCLUSIONS: The SMT provides a novel method for evaluating the sense of smell that shows good general agreement with the UPSIT. Its minimal dependence on language and cognitive abilities provides some advantages over odor identification tests. There is some indication that the UPSIT may be more sensitive to olfactory (and/or nonolfactory) deficits. We conclude that sniffing behavior can be exploited for the clinical evaluation of olfaction. A comparison of performance on odor identification and sniffing tests may provide novel insight into the nature of olfactory problems in a variety of patient populations.

Optimism, social support and psychosocial functioning among women with breast cancer.

Personality, psychosocial, demographic and medical variables have been identified as correlates of adjustment to breast cancer and quality of life (QoL). Most studies have examined relationships between personality, social support and adjustment to cancer in predominantly middle-class Caucasian samples, thus limiting the generalizability of their findings. Eighty-one female outpatients at a medical oncology breast clinic in a county general hospital serving primarily indigent Hispanic and African-American patients completed measures assessing demographic and medical information, health-related QoL, cancer-specific distress, mood disturbance, dispositional optimism and satisfaction with social support. Older age, receipt of treatment and greater optimism accounted for 41% of the variance in emotional well-being (p<0.01). Absence of family history of breast cancer, receipt of treatment and optimism accounted for 43% of the variance in functional well-being (p<0.01). Optimism and satisfaction with social support accounted for 43% of the variance in social/family well-being (p<0.01). Absence of treatment (not yet treated) and pessimism accounted for 31% of the variance in cancer-specific distress (p<0.01). Finally, family history of breast cancer and pessimism accounted for 48% of the variance in mood disturbance (p<0.001). Family history of breast cancer and pessimism were related to mood disturbance (p<0.001). No between-group differences were found for race/ethnicity for any of the variables. Encouraging positive expectations and facilitating social support may help women in public sector medical settings cope with the stressful demands of diagnosis and treatment of breast cancer regardless of race/ethnicity.

What does the family pictures subtest of the Wechsler Memory Scale-III measure? Insight gained from patients evaluated for epilepsy surgery.

The Family Pictures (FP) task is a new subtest of the Wechsler Memory Scale Version III (WMS-III) used to assess visual memory and learning. This study assessed the extent to which different cognitive abilities contribute to performance on the FP task in 125 patients evaluated for epilepsy surgery. Results indicated that the FP task relies heavily on auditory-verbal based cognitive abilities, as well as visual memory, and may better represent a general measure of memory performance. These results raise questions about the appropriateness of including FP task performance in the calculations of the WMS-III Visual Index scores.
