Long-term neurocognitive and psychological outcomes in meningioma survivors: Individual changes over time and radiation dosimetry.

Background: This study investigates long-term changes in neurocognitive performance and psychological symptoms in meningioma survivors and associations with radiation dose to circumscribed brain regions.

Methods: We undertook a retrospective study of meningioma survivors who underwent longitudinal clinical neurocognitive assessments. Change in neurocognitive performance or psychological symptoms was assessed using reliable change indices.

Return to work following mild traumatic brain injury: Psychological and cognitive factors in a litigating sample in the post acute stage of recovery.

The purpose of this study was to investigate return to work (RTW) rates following a single uncomplicated mild Traumatic Brain Injury (mTBI) in the post-acute stage in the context of active litigation. More specifically, we sought to determine what psychological and/or cognitive factors predict a RTW after mTBI. Archival data were obtained from a random sample of litigating patients ( = 125; 54% female; mean age: 42.

Neurocognitive impairment, neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms in patients with newly diagnosed glioblastoma.

Background: In addition to poor survival rates, individuals with glioblastoma (GBM) are at risk of neurocognitive impairment due to multiple factors. This study aimed to characterize neurocognitive impairment, neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms in newly diagnosed GBM patients; and to examine whether neurobehavioral symptoms, fatigue, sleep, and depressive symptoms influence neurocognitive performance.

Methods: This study was part of a prospective, inception cohort, single-arm exercise intervention in which GBM patients underwent a neuropsychological assessment shortly after diagnosis (median 4 weeks; ie, baseline) and 3, 6, 12, and 18 months later, or until tumor progression.

Neurocognitive Performance in Adults Treated With Radiation for a Primary Brain Tumor.

Purpose: The contributory effects of radiation dose to different brain regions on neurocognitive performance after radiation therapy (RT) for primary brain tumors is not well known.

Methods And Materials: In this retrospective cohort study, 30 patients with brain tumors treated with photon RT were identified, and radiation dosimetric parameters across brain regions were calculated. All patients had longitudinal neurocognitive evaluations at baseline and after treatment.

Radiation dose to circumscribed brain regions and neurocognitive function in patients with meningioma.

Background: Although radiation (RT) is standard treatment for many brain tumors, it may contribute to neurocognitive decline. The objective of this study was to investigate associations between RT dose to circumscribed brain regions and specific neurocognitive domains in patients with meningioma.

Methods: We undertook a retrospective study of 40 patients with meningioma who received RT and underwent an in-depth clinical neurocognitive assessment.

Long-term neurocognitive, psychological, and return to work outcomes in meningioma patients.

Introduction: This study aimed to investigate long-term neurocognitive, psychological, and return to work (RTW) outcomes in meningioma patients, and to explore whether neurocognitive and psychological factors influence RTW outcomes in this population.

Methods: In this retrospective study, 61 meningioma patients completed in-depth clinical neuropsychological assessments. Of these participants, 42 were of working-age and had RTW information available following neuropsychological assessment.

Reliability of the French-Canadian adaptation of the Personality Assessment Inventory: Medical-legal implications.

The Personality Assessment Inventory (PAI) is a reliable multidimensional psychometric inventory that is increasingly being used in the medical-legal context. To date, 18 language adaptations of the PAI exist, yet only the Spanish, Greek and German language versions have been examined psychometrically. This study evaluated the psychometric properties of the French-Canadian version of the PAI by comparing mean scale and subscale scores between the French-Canadian and English language versions, and analyzing the internal consistency and mean item inter-correlations (MICs) of each version in a sample of 50 bilingual university students.

The effect of diagnostic terminology on cognitive, emotional, and post-concussive sequelae following mild brain injury.

Objective: We sought to determine whether the diagnostic terms 'mild traumatic brain injury (mTBI)' and 'concussion' result in differences in perceived cognitive, emotional, and post-concussive sequelae.

Method: A total of 81 healthy university students (79% female; 69% of Asian descent) were randomly assigned to one of two conditions: mTBI ( = 41), or concussion ( = 40), and were instructed to simulate on a battery of cognitive (Neuropsychological Assessment Battery - Screening Module), emotional (Beck Anxiety Inventory, Beck Depression Inventory-II), and post-concussive (Rivermead Postconcussive Symptoms Questionnaire) measures.

Results: There were no significant group differences between expected cognitive, emotional, or post-concussive consequences.

Spiritual Well-Being as a Predictor of Emotional Impairment Following Mild Traumatic Brain Injury.

Traumatic brain injury (TBI) is a leading cause of death and disability, with injuries classified as mild in severity being the most frequently sustained. While the majority of patients recover within 3 months post-injury, many individuals continue to experience debilitating emotional sequelae several months after the injury. While spiritual well-being has been shown to carry protective benefits against both depression and anxiety in the general population, it has not been investigated as a protective factor in this population.

The relationship between post-traumatic growth and return to work following mild traumatic brain injury.

To investigate the prevalence of post-traumatic growth (PTG) following mild traumatic brain injury (mTBI) and to examine whether PTG is associated with vocational status. Archival data from a random sample of 74 individuals who sustained mTBI (mean age: 43.23; male, 55%) were obtained from a larger sample of litigating patients who were referred for a neuropsychological examination.

Developing a short version of the Toronto Structured Interview for Alexithymia using item response theory.

The Toronto Structured Interview for Alexithymia (TSIA) was developed to provide a structured interview method for assessing alexithymia. One drawback of this instrument is the amount of time it takes to administer and score. The current study used item response theory (IRT) methods to analyze data from a large heterogeneous multi-language sample (N = 842) to investigate whether a subset of items could be selected to create a short version of the instrument.

Neuropsychological analysis of an idiot savant: A case study.

Although biological etiologies and diffuse anatomical changes have been provided as plausible explanations for the unusual behaviors observed in idiot savants, no neuropsychological case studies or explanations for these behaviors are found in the literature. We present a case in which the "diagnosis" of idiot savant was based on historical, clinical, and test data. To assess his calendar abilities, this individual was subsequently tested over a period of six months on his ability to determine the day of the week across approximately 1,000 years.
