RESUMEN

The role of cognitive function in quality of life is important among the growing numbers of survivors after cancer treatment. The authors conducted a prospective cohort study of 106 adults evaluated 5.6 months (median) after diagnosis and 77 of 83 (93%) survivors 12 months later with neuropsychological assessments yielding information about simple reaction time to stimuli and other aspects of cognitive function and with two quality of life measures. The two most consistent predictors of change in quality of life were baseline quality of life ratings and simple reaction time. This novel finding about simple reaction time warrants further confirmation.

RESUMEN

BACKGROUND: Patients' substance use problems are a particularly understudied aspect of psychosocial variables in cancer treatment. OBJECTIVES: The specific hypothesis tested was that lifetime substance use disorders increased the risk of adverse outcome, in the context of other psychosocial and clinical characteristics demonstrated in other studies to have an impact on treatment outcome. METHOD: Prospective cohort study of 106 adults with chronic myelogenous leukemia or primary myelodysplastic syndrome. None satisfied criteria for current substance abuse or dependence, but the lifetime rates of substance use disorders in this sample were 28% for alcohol, 12% for cannabis, and 9% for cocaine. RESULTS: Participants received treatment as directed by their physicians, and were followed until death or the end of the study (median 1.5 years). Twenty-eight died. Multivariate survival analysis identified three predictors of outcome: lifetime cocaine use, associated with a six-fold increased risk of death (p = .04), and two protective variables, baseline hemoglobin (p = .002) and estimated intelligence quotient (IQ) (p = .04). CONCLUSION: The results of this study highlight the potential significance of substance use disorders, and lifetime cocaine diagnoses in particular, on treatment outcome for people with chronic myelogenous leukemia or myelodysplastic syndrome. Whereas neither lifetime alcohol nor cannabis use were associated with survival on either the univariate or multivariate models of survival, lifetime cocaine diagnoses were associated with significant six-fold increased risk of death (p = .04).

RESUMEN

Functional MRI (fMRI) is often used for presurgical language lateralization. In the most common approach, a laterality index (LI) is calculated on the basis of suprathreshold voxels. However, strong dependencies between LI and threshold can diminish the effectiveness of this technique; in this study we investigated an original methodology that is independent of threshold. We compared this threshold-independent method against the common threshold-dependent method in 14 patients with epilepsy who underwent Wada testing. In addition, clinical results from electrocortical language mapping and postoperative language findings were used to assess the validity of the fMRI lateralization method. The threshold-dependent methodology yielded ambiguous or incongruent lateralization outcomes in 4 of 14 patients in the inferior frontal gyrus (IFG) and in 6 of 14 patients in the supramarginal gyrus (SMG). Conversely, the threshold-independent method yielded unambiguous lateralization in all the patients tested, and demonstrated lateralization outcomes incongruent with clinical standards in 2 of 14 patients in IFG and in 1 of 14 patients in SMG. This validation study demonstrates that the threshold-dependent LI calculation is prone to significant within-patient variability that could render results unreliable; the threshold-independent method can generate distinct LIs that are more concordant with gold standard clinical findings.

RESUMEN

OBJECTIVE Idiopathic normal pressure hydrocephalus (iNPH) is characterized by ventriculomegaly, gait difficulty, incontinence, and dementia. The symptoms can be ameliorated by CSF drainage. The object of this study was to identify factors associated with shunt-responsive iNPH. METHODS The authors reviewed the medical records of 529 patients who underwent shunt placement for iNPH at their institution between July 2001 and March 2015. Variables associated with shunt-responsive iNPH were identified using bivariate and multivariate analyses. Detailed alcohol consumption information was obtained for 328 patients and was used to examine the relationship between alcohol and shunt-responsive iNPH. A computerized patient registry from 2 academic medical centers was queried to determine the prevalence of alcohol abuse among 1665 iNPH patients. RESULTS Bivariate analysis identified associations between shunt-responsive iNPH and gait difficulty (OR 4.59, 95% CI 2.32-9.09; p < 0.0001), dementia (OR 1.79, 95% CI 1.14-2.80; p = 0.01), incontinence (OR 1.77, 95% CI 1.13-2.76; p = 0.01), and alcohol use (OR 1.98, 95% CI 1.23-3.16; p = 0.03). Borderline significance was observed for hyperlipidemia (OR 1.56, 95% CI 0.99-2.45; p = 0.054), a family history of hyperlipidemia (OR 3.09, 95% CI 0.93-10.26, p = 0.054), and diabetes (OR 1.83, 95% CI 0.96-3.51; p = 0.064). Multivariate analysis identified associations with gait difficulty (OR 3.98, 95% CI 1.81-8.77; p = 0.0006) and alcohol (OR 1.94, 95% CI 1.10-3.39; p = 0.04). Increased alcohol intake correlated with greater improvement after CSF drainage. Alcohol abuse was 2.5 times more prevalent among iNPH patients than matched controls. CONCLUSIONS Alcohol consumption is associated with the development of shunt-responsive iNPH.

RESUMEN

The mechanism by which the brain integrates visual and emotional information remains incompletely understood, and can be studied through focal lesions that selectively disrupt this process. To date, three reported cases of visual hypoemotionality, a vision-specific form of derealization, have resulted from lesions of the temporo-occipital junction. We present a fourth case of this rare phenomenon, and investigate the role of the inferior longitudinal fasciculus (ILF) in the underlying pathophysiology. A 50-year-old right-handed male was found to have a right medial temporal lobe tumor following new-onset seizures. Interstitial laser ablation of the lesion was complicated by a right temporo-parieto-occipital intraparenchymal hemorrhage. The patient subsequently experienced emotional estrangement from visual stimuli. A lesion overlap analysis was conducted to assess involvement of the ILF by this patient's lesion and those of the three previously described cases, and diffusion tensor imaging was acquired in our case to further investigate ILF disruption. All four lesions specifically overlapped with the expected trajectory of the right ILF, and diminished structural integrity of the right ILF was observed in our case. These findings implicate the ILF in visual hypoemotionality, suggesting that the ILF is critical for integrating visual information with its emotional content.

RESUMEN

Practical experience is central to the education and training of neuropsychologists, beginning in graduate school and extending through postdoctoral fellowship. However, historically, little attention has been given to the structure and requirements of practicum training in clinical neuropsychology. A working group of senior-level neuropsychologists, as well as a current postdoctoral fellow, all from a diverse range of settings (The AACN Practicum Guidelines Workgroup), was formed to propose guidelines for practicum training in clinical neuropsychology. The Workgroup reviewed relevant literature and sought input from professional organizations involved in education and training in neuropsychology. The proposed guidelines provide a definition of practicum training in clinical neuropsychology, detail entry and exit criteria across competencies relevant to practicum training in clinical neuropsychology, and discuss the relationship between doctoral training programs and practicum training sites. The proposed guidelines also provide a methodology for competency-based evaluation of clinical neuropsychology practicum trainees and outline characteristics and features that are integral to an effective training environment. Although the guidelines discussed below may not be implemented in their entirety across all clinical neuropsychology practicum training sites, they are consistent with the latest developments in competency-based education.

RESUMEN

This study examined the course of neuropsychological functioning in patients with chronic myelogeous leukemia (n = 91) or myelodysplastic syndrome (n = 15) who underwent standard treatment for their disease or allogeneic hematopoietic stem cell transplantation (HSCT) at baseline, 12 months, and 18 months post-treatment. At baseline, 23% of the participants (n = 75) in the longitudinal sample had Z-scores on at least one of the neuropsychological tests that were <1.4. Participants in the study showed improvement over baseline at the 12 and 18 months assessments. The average Z-scores for the six cognitive domains in the longitudinal data set over the course of the study ranged from -0.89 to 0.59. Significant predictors of change in neuropsychological test scores included age, with older participants showing less improvement over time. Other predictors included baseline cognitive domains (language, memory, and attention), previous cocaine use, disease status, intelligence quotient, and quality of life measures. Findings support previous studies in patients with hematological malignancies who showed cognitive impairments at baseline prior to HSCT. However, there was little evidence for further cognitive decline over the course of 18 months.

RESUMEN

BACKGROUND: The growing numbers of survivors of innovative cancer treatments, such as hematopoietic stem cell transplantation (HSCT), often report subsequent cognitive difficulties. The objective of this study was to evaluate and compare neurocognitive changes in patients with chronic myelogenous leukemia (CML) or primary myelodysplastic syndrome (MDS) after allogeneic HSCT or other therapies. METHODS: In this prospective cohort study, serial evaluations of attention, concentration, memory, mood, and quality of life were used in a consecutive sample of 106 eligible patients who had CML (n = 91) or MDS (n = 15) at enrollment and then 12 months and 18 months after HSCT or other therapy. RESULTS: The 3 evaluations at enrollment, 12 months, and 18 months were completed by 98%, 95%, and 89% of surviving participants, respectively. Among all patients, there was significant improvement in memory over 18 months. For example, the 45 patients who underwent HSCT (42 patients with CML and 3 patients with MDS) compared favorably with the patients who received other treatment on most measures of neuropsychological function, except they had improved mental health (P = .034), worse physical function (P = .049), and more difficulty with coordination and fine motor speed bilaterally (dominant hand, P = .005; nondominant hand, P = .0019). Patients with CML overall had improved phonemic fluency (P = .014). CONCLUSIONS: The current study indicated that time and diagnosis may be important factors when assessing neurocognitive and other changes. Complaints regarding "chemobrain" after HSCT merit further study, because deficits actually may predate the initiation of treatment and subsequently may improve. The study results could reassure prospective HSCT recipients, because HSCT compared favorably with other treatments when mental status side effects were considered.

RESUMEN

Over the last few decades, long-term survival rates of children diagnosed with the two most common forms of childhood cancer, acute lymphoblastic leukemia (ALL) and brain tumors have improved substantially. Neurodevelopmental and psychosocial sequelae resulting from these diseases and their treatment have a direct impact on the developing brain and on the quality of life of these children and their families. The focus of this article is on optimizing neuropsychological and adaptive outcomes for children who have been successfully treated for these cancers and whose prospects for long-term survival are increasingly encouraging. We present a model for understanding systemic interactions among the multiple factors that influence the child's development over time and take into account contextual variables. Strategies for optimizing cognitive and psychosocial outcomes or ameliorating late effects need to consider treatment histories, specific stages of development, the contextual demands/developmental challenges associated with each, and the resources (internal and external to the child) available to meet these challenges. The challenges faced by survivors at the early childhood, middle childhood, adolescent, and emerging adulthood stages are discussed. We review different types of interventions and discuss how these can contribute to optimal functioning in survivors of childhood ALL and brain tumors.

RESUMEN

We present a case illustrating the use of eye movement desensitization and reprocessing (EMDR) in the treatment of psychogenic seizures. These seizures were events lasting many hours, necessitating frequent emergency room visits and an extensive medical work up. Given the patient's history, posttraumatic stress disorder (PTSD) was diagnosed. EMDR is widely used as a treatment modality for PTSD, and the patient was referred for once-per-week treatment, with complete recovery after 18 months of therapy. The impact of her recovery on her quality of life was astonishing. This case supports the notion that EMDR can be an effective alternative treatment for psychogenic seizures, especially when the history reveals a traumatic event or abusive experiences.
