Behavioral neuropsychology: Past, present, and future direction with organically based affect/mood disorders
Neuropsychology Review - Tập 2 - Trang 65-107 - 1991
Kathryn Lawson-Kerr, Patrick Smith, DuAnn Beck
Affective/mood disturbances have been widely described in association with central nervous system dysfunction. There have been multiple divergent viewpoints regarding the origin of these disorders, however. This is not surprising, as theories evolve in relation to our degree of technological advancement. This review describes the evolution of some of these views, and discusses the advantages of behavioral neuropsychology as an effective approach to assessment/treatment in this context. Although there have been few articles published describing the use of behaviorally based approaches to treat these disorders, it is thought that this approach shows promise, particularly when combined with information based on neuropsychological assessment data. Future directions for the continued evolution of this field are outlined.
Exploring Predictors of Outcome in the Psychosis Prodrome: Implications for Early Identification and Intervention
Neuropsychology Review - Tập 19 - Trang 280-293 - 2009
Tara A. Niendam, Maria Jalbrzikowski, Carrie E. Bearden
Functional disability is a key component of many psychiatric illnesses, particularly schizophrenia. Impairments in social and role functioning are linked to cognitive deficits, a core feature of psychosis. Retrospective analyses demonstrate that substantial functional decline precedes the onset of psychosis. Recent investigations reveal that individuals at clinical-high-risk (CHR) for psychosis show impairments in social relationships, work/school functioning and daily living skills. CHR youth also demonstrate a pattern of impairment across a range of cognitive domains, including social cognition, which is qualitatively similar to that of individuals with schizophrenia. While many studies have sought to elucidate predictors of clinical deterioration, specifically the development of schizophrenia, in such CHR samples, few have investigated factors relevant to psychosocial outcome. This review integrates recent findings regarding cognitive and social-cognitive predictors of outcome in CHR individuals, and proposes potential directions for future research that will contribute to targeted interventions and improved outcome for at-risk youth.
Quality of Life and Neurological Illness: A Review of the Literature
Neuropsychology Review - - 1999
Rachel Murrell
This article highlights some of the conceptual and methodological problems associated with quality of life (QoL) measurement in individuals with neurological illness. It is suggested that these problems have contributed to the underdeveloped status of QoL research in neurological settings. Many of the existing QoL measures that have been used, or show potential for use with individuals with neurological illness, are reviewed in terms of their theoretical basis, content, and practicality. A large proportion of these measures fail to meet adequate psychometric standards and/or have rarely been psychometrically tested. The confusion that surrounds adequate psychometric standards is discussed, and the dynamic nature of QoL is highlighted as a factor that requires further attention. Research addressing the discrepancies between proxy and patient ratings of patient QoL is also warranted. More focused research in these areas may contribute to a clearer understanding of how to assess QoL in individuals with neurological illness.
Contribution of Callosal Connections to the Interhemispheric Integration of Visuomotor and Cognitive Processes
Neuropsychology Review - Tập 20 - Trang 174-190 - 2010
Tilman Schulte, Eva M. Müller-Oehring
In recent years, cognitive neuroscience has been concerned with the role of the corpus callosum and interhemispheric communication for lower-level processes and higher-order cognitive functions. There is empirical evidence that not only callosal disconnection but also subtle degradation of the corpus callosum can influence the transfer of information and integration between the hemispheres. The reviewed studies on patients with callosal degradation with and without disconnection indicate a dissociation of callosal functions: while anterior callosal regions were associated with interhemispheric inhibition in situations of semantic (Stroop) and visuospatial (hierarchical letters) competition, posterior callosal areas were associated with interhemispheric facilitation from redundant information at visuomotor and cognitive levels. Together, the reviewed research on selective cognitive functions provides evidence that the corpus callosum contributes to the integration of perception and action within a subcortico-cortical network promoting a unified experience of the way we perceive the visual world and prepare our actions.
Neuropsychological Evaluation of Everyday Memory
Neuropsychology Review - Tập 8 Số 4 - Trang 203-227 - 1998
Garcia, Miguel Perez, Garcia, Juan F. Godoy, Guerrero, Nieves Vera, Triguero, Jose A. Laserna, Puente, Antonio E.
The evaluation of everyday memory (EM) was reviewed and reconceptualized. EM has established new objectives of study and the development of new methods to reach these objectives . At the basic level, this approach has already produced important discoveries and the development of new principles about memory and functioning. At the clinical level, this new area of investigation has resulted in evaluating deficits of EM, which is defined as what daily life functions remain impaired after a deficit pathology has occurred. A type of evaluation has evolved that is oriented toward treatment and extremely useful in designing rehabilitation programs for individuals with alterations in memory.

Hypoxia and Inflammation in Children with Sickle Cell Disease: Implications for Hippocampal Functioning and Episodic Memory
Neuropsychology Review - Tập 24 - Trang 252-265 - 2014
Mary Iampietro, Tania Giovannetti, Reem Tarazi
Children with sickle cell disease (SCD) suffer from systemic processes (e.g., chronic anemia, recurrent hypoxic-ischemic events, chronic inflammation) that have been associated with neurocognitive impairment in a range of clinical populations, but which have been largely understudied in relation to specific domains of cognitive functioning in children with SCD. This review focuses on episodic memory, as the hippocampus may be especially vulnerable to the systemic processes associated with SCD. The first part of the paper outlines the pathophysiology of SCD and briefly reviews the extant literature on academic and cognitive functioning in children with SCD, emphasizing the dearth of research on episodic memory. Next, the complex systemic processes of hypoxia and inflammation associated with SCD are reviewed, along with research that has associated these processes with hippocampal damage and memory impairment. The paper concludes with suggestions for future research that are informed, in part, by the literature on developmental amnesia.
Enhancing Cognitive Functioning in Healthly Older Adults: a Systematic Review of the Clinical Significance of Commercially Available Computerized Cognitive Training in Preventing Cognitive Decline
Neuropsychology Review - Tập 27 - Trang 62-80 - 2017
Tejal M. Shah, Michael Weinborn, Giuseppe Verdile, Hamid R. Sohrabi, Ralph N. Martins
Successfully assisting older adults to maintain or improve cognitive function, particularly when they are dealing with neurodegenerative disorders such as Alzheimer’s disease (AD), remains a major challenge. Cognitive training may stimulate neuroplasticity thereby increasing cognitive and brain reserve. Commercial brain training programs are computerized, readily-available, easy-to-administer and adaptive but often lack supportive data and their clinical validation literature has not been previously reviewed. Therefore, in this review, we report the characteristics of commercially available brain training programs, critically assess the number and quality of studies evaluating the empirical evidence of these programs for promoting brain health in healthy older adults, and discuss underlying causal mechanisms. We searched PubMed, Google Scholar and each program’s website for relevant studies reporting the effects of computerized cognitive training on cognitively healthy older adults. The evidence for each program was assessed via the number and quality (PEDro score) of studies, including Randomized Control Trials (RCTs). Programs with clinical studies were subsequently classified as possessing Level I, II or III evidence. Out of 18 identified programs, 7 programs were investigated in 26 studies including follow-ups. Two programs were identified as possessing Level I evidence, three programs demonstrated Level II evidence and an additional two programs demonstrated Level III evidence. Overall, studies showed generally high methodological quality (average PEDro score = 7.05). Although caution must be taken regarding any potential bias due to selective reporting, current evidence supports that at least some commercially available computerized brain training products can assist in promoting healthy brain aging.
Are Sleep Complaints Related to Cognitive Functioning in Non-Central Nervous System Cancer? A Systematic Review
Neuropsychology Review - Tập 32 - Trang 483-505 - 2021
Mylène Duivon, Bénédicte Giffard, Béatrice Desgranges, Joy Perrier
Patients with non-central nervous system (CNS) cancer frequently report cognitive complaints, that are recurrent and affect their quality of life. In order to improve supportive care of these cognitive difficulties, it is important to identify associated factors. Sleep disturbance is a good candidate to study, as patients with non-CNS cancer frequently report sleep disorders, and sleep plays a key role in cognitive functioning. The objective of the present systematic review was to summarize the results of studies evaluating the relationship between cognition and sleep in non-CNS cancer, and to highlight the need for further studies. PubMed [Medline] and Scopus databases were screened from April to November 2020 for studies published in English evaluating the association between cognition and sleep in adults with non-CNS cancer. The characteristics and risk of bias for each of the 30 included studies have been reported. Greater cognitive complaints in patients with non-CNS cancer were related to poorer self-reported sleep quality in almost all studies (n = 22/24). By contrast, around half of the studies reported a significant association between poorer neuropsychological performances and sleep complaints (n = 5/11). The studies were found to have several limitations, such as the lack of a control group, which would have shed the light on the period of occurrence of this association (e.g. after cancer diagnosis or after cancer treatments). Our review also identified factors that may influence the relationship between cognition and sleep. Recommendations are given for improving the methodology of future studies and extending the impact of their results.
