Neurocognitive function before and after surgery for insular gliomas.

Object: Insular gliomas can be resected with acceptable rates of neurological morbidity, but little is known with regard to impairment of higher-order neurocognitive functions. The frequency and functional impact of neurocognitive deficits in patients with gliomas has until recently been underappreciated. The authors therefore examined neurocognitive function in patients with insular gliomas and compared the findings in this group to those in a matched control group of patients with gliomas in nearby brain regions.

Neurocognitive and quality of life measures in patients with metastatic brain disease.

The assessment of neurocognitive function and quality of life (QOL) in patients with brain metastases has become increasingly recognized as an important addition to traditional outcome measures such as length of survival and time to disease progression. Although objective assessment of neurocognitive function using standardized neuropsychological tests is well established, QOL represents a more subjective concept for which no gold standard assessment tool has been identified. Assessment of both neurocognitive function and QOL should involve reliable and valid measures that are sensitive to the cognitive domains and aspects of patient well-being that are most affected by brain metastases and associated treatments.

Instruments for estimation of health-related quality of life in patients with skull base neoplasms.

With advances in treatment of patients with tumors of the skull base and associated improvement in length of survival, the need for assessment of quality of life (QOL) is becoming increasingly apparent. A thorough assessment of QOL, including functional, physical, social, and emotional status, as well as disease-specific symptoms, allows for comparison of treatments and informs treatment decisions. In addition, it allows for problems following intervention to be identified and addressed, thereby assisting patients in their pursuits of returning to their normal activities and level of functioning.

Neuropsychological sequelae of non-central nervous system cancer and cancer therapy.

Cancer patients report numerous adverse symptoms associated with their disease and treatment including cognitive dysfunction, fatigue, and affective distress. Cognitive dysfunction is ubiquitous in patients with primary central nervous system (CNS) cancer and recent evidence has documented similar deficits in patients with non-CNS cancer as well. Both the cancer itself and treatments including chemotherapy, biological response modifiers, and hormonal therapies have been demonstrated to adversely impact cognitive and neurobehavioral function.

Is basic memory structure invariant across epilepsy patient subgroups?

It is well known that epilepsy patients often exhibit material-specific deficits in memory for verbal versus nonverbal material. However, it is also apparent that such deficits are not always discernible, and that numerous factors may potentially moderate the degree to which fractionation between verbal and nonverbal material is evident. Using confirmatory factor analysis, we compared the relative fit of one-factor (general) and two-factor (material-specific) models of memory in data from 330 patients with intractable seizure disorder.

Frequency of panic symptoms in psychogenic nonepileptic seizures.

This study investigates the frequency of symptoms of panic attack in a sample of adults (n = 18) and adolescents (n = 21) who were evaluated for intractable seizure disorder and diagnosed with psychogenic nonepileptic seizures (PNES). Medical records were retrospectively reviewed for symptoms associated with their typical seizure events as documented by the attending epileptologist. Adolescents, as a group, reported significantly more symptoms of panic attack than adults.
