Dualistic thinking has informed our understandings since the historical times (e.g., including Aristotle, Plato), and examples of dualistic thinking would include the categorization of the difficulties experienced by persons following traumatic brain injury into emotional and cognitive difficulties. This 2017 review(The full-text will be published soon) provides insights into the integrative functioning of the brain, which would argue against such categorization. Objective: This paper will address how anomalies of executive function after TBI can translate into altered social behaviour that has an impact on a person’s capacity to live safely and independently in the community.Method: Review of literature on executive and neurobehavioural function linked to c...

I attended a conference/ summit on brain technology today, and came across a number of great technological helpful tools. One is curatio.me; an app to download and build patient support networks, which could include a brain injury and/ or dementia network as well as caregiver networks.

Last post in today's series on cognitive aging, this article addresses the ethical dilemma that arises when patients with mild cognitive impairment are unable to take adequate care of themselves but, because they do not have moderate or severe dementia, maintain their legal right to make health care decisions, resulting in Elder Self-Neglect. Cases of elder self-neglect require physicians to balance the patient’s wish for independence and the risks of poor self-care.

This study focuses on internet resources that emphasized audience members’ personal responsibility for managing dementia risk. It is argued that such representations promote a moral identity in regard to brain health in which an ethic of self-responsibility is central. The implications of such identity construction in a context of increasing prevalence of dementia diagnosis are discussed. For example, online health messages about dementia have the potential to contribute to the reproduction of a potentially repressive neoliberal rationality of self-discipline and risk management. This study aims to contribute to understanding of contemporary sense-making around the issue of dementia risk prevention—in particular, how representations of dementia prevention might mediate people’s subjective experience of, and responses to, cognitive aging and adds to currently available information by examining how online information about dementia risk and prevention works to construct participation in prevention as desirable, necessary, and obligatory, despite ongoing debate about the benefit of such practices. The Internet has been argued to provide diverse sites for health communication and promotion, including issues that constitute major public health priorities su...

Subjective cognitive decline can be suggestive of later objective cognitive decline. However, many factors can be impacting subjective cognitive well-being. This 2017 free article comments on the connection between subjective cognitive decline, depression, and brain abnormalities. Subjective cognitive decline (SCD), or self-perceived worsening of cognitive function in the absence of objective cognitive deficits, has attracted significant scientific attention for decades, because this phenomenon might reflect the earliest signs of an emerging neurodegenerative disease.1...

In addition to the previous article on caregivers' burden, I am posting an article on the changes that can be effected in people with chronic traumatic brain injury (with all its challenges of pilot data, but notwithstanding pretty revolutionary, and make no mistake, it's just the start of the movement). In short, in my mind, it's not only psychological/ emotional support that vulnerable people need but rather a comprehensive approach that provides people with the 'how-to's' of problem solving including the cognitive training and emotional support and allowing them to reach their potential. At present, it seems that society "thinks" it easier to "plateau" people with brain injury; an expensive approach for society and potentially a devastating approach for the person plateau'd, when it actually is possible to provide the interventions to allow people after brain injury to become a participating member again. Facilitating functional recovery following brain injury is a key goal of neurorehabilitation. Direct, objective measures of changes in the brain are critical to understanding how and when meaningful changes occur, however, assessing neuroplasticity using ...

Much research is done in the population of traumatic brain injury. However, caregivers' needs are largely unacknowledged or ignored. Therefore, this 2017 open access article on: "Caregiver’s Burden of the Patients With Traumatic Brain Injury" is topic of today's post.

Fatigue following traumatic brain injury is an long-lasting symptom that has not received sufficient attention in this population. Unfortunately, we do not understand the construct, in general or in this specific population. Fatigability refers to the brain/ neural correlates of fatigue, whereas fatigue refers to a person's experience/ awareness of fatigue, i.e. 2 different constructs/ entities. Importantly, there is evidence that cognition as well as sleep and mood are all different constructs, albeit correlated with the fatigue experience. Given the importance of the fatigue construct, the following 2017 article is posted here. Introduction: Fatigue is the most frequently reported persistent symptom following a mild traumatic brain injury (mTBI), but the explanations for the persisting fatigue symptoms in mTBI remain controversial. In this study, we investigated the change of cerebral blood flow during the performance of a...

A 2017 article on the: "Neuroplastic Changes Induced by Cognitive Rehabilitation in Traumatic Brain Injury: A Review" suggests effectiveness of cognitive rehabilitation. I had a few weeks ago posted a review on cognitive rehabilitation interventions suggesting 'no effects' of cognitive rehabilitation. Obviously, 'no effect' may just mean that cognitive rehabilitation methods are not properly utilized/ understood in practice, which would not be too surprising given the dearth of educational opportunities on how to do cognitive rehabilitation.

This 2017 article provides info on the building blocks of higher/ complex cognitive functions, and thus suggests how to adjust the principle of specificity in cognitive rehabilitation (i.e., specificity- cognitive remediation needs to be geared towards the affected functions in order to promote benefits). For example, if memory difficulties are due to attention and information processing difficulties, it is the latter functions (information processing, attention) that need to be trained prior to using memory exercises (this is in addition to teaching strategies to support attention, information processing, and memory). Background. While older adults are able to attend to goal-relevant information, the capacity to ignore irrelevant or distracting information declines with advan...

Contrary to the usual info on physical activity and cognitive decline, this study suggests that physical activity has no neuroprotective effect (i.e., decreasing risk of developing dementia). However, a higher global cognitive score was reported at age 80 for those participants who followed physical activity recommendations (there was no cognitive score difference at age 50). One of the questions would be the difference between "normal" cognitive decline and dementia, two different processes with one being part of normal aging, the other being a neurodegenerative disease. This may suggest different populations. Apparently, results change depending on which participants are included in the analysis, the complete sample including demented and those who did not develop dementia versus analysis on a sub sample of dementia cases only (see "data from the AGES-Reykjavik Study and CAIDE" in article section: Comparison to other studies.) Important to this idea, Brain Maintenance (that is brain reserve) and Cognitive reserve were uncorrelated in another study such that values on one measure did not imply anything about the other measure (https://academic.oup.com/cercor/article-abstract/27/8/3962/3056407/Cognitive-Reserve-and-Brain-Maintenance-Orthogonal

As suggested in the previous post, here is the 2017 open access article of the Cochrane reviews protocol, suggesting that psychological interventions have been hypothesised to be able to prevent the development or maintenance of persistent post concussion symptoms following mTBI, or to treat postconcussion symptoms that have already become persistent. Thus, a systematic review will be conducted to id benefits or harmful effects of psychological interventions: This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:To assess the benefits and harms of psychological interventions for people with persisting postconcussion symptom...

Here is an Opinion statement that I find rather worrying given its oversimplification. While I agree that PTSD following TBI (incl mild TBI) definitely needs attention, and mental health care is likely key for this type of TBI consequence, the implied idea that long-term consequences of mTBI/ TBI are primarily mental health related consequences (e.g., non-neurological) is certainly oversimplified, and worse, it potentially can invalidate patients' experience and thus be harmful if other relevant factors are ignored. Evidence actually is available suggesting that other factors, besides premorbid/ concurrent mental health, are predictive of outcome following mTBI, including absence of nausea/vomiting upon entrance to the ED, pain including headache severity, and intracranial findings on initial CT. Currently, however, the idea that psychological treatments are successful in improving recovery following mTBI remains hypothetical (see next post). Deteriorating mental health (i.e. emotional difficulties) following TBI/mTBI may rather be secondary to cognitive difficulties, fatigue issues, and lack of societal or other support. Symptoms that persist beyond the expected period of recovery following a mild traumatic brain injury (mTBI)/concussion are strongly linked to non-neurologic variables, notably mental health conditions

One of the unresolved questions in the TBI literature relates to the risk of dementia following TBI. Here is a longitudinal study investigating the risk of dementia following mild TBI. Some of the major benefits of longitudinal studies include the direct identification of intraindividual change while also allowing for identification of interindividual variability in intraindividual change. In other words, this design can remove the bias of individual differences that remain unidentified in cross sectional designs and therefore may be misinterpreted in cross sectional designs as study effect. Traumatic brain injury is suggested to be a significant risk factor for dementia. However, little research has been conducted on long-term neuropsychological outcomes after head trauma. Participants from the Australian Imaging, Biomarkers and Lifestyle Study of Ageing (AIBL) who had recovered after…

I am often asked by clients to provide dietary advise for brain health, and I have posted a number of articles and posts regarding diet in support of brain health. Here is a 2017 article that provides data from the Hellenic Longitudinal Investigation of Ageing and Diet (HELIAD), an on-going population-based study. This study provides evidence that adherence to the MeDi is associated with better cognitive performance and lower dementia rates in Greek elders.

Last post for today, also from the University of Exeter, UK: suggesting that One in three cases of dementia could be potentially prevented if brain health is improved throughout life by targeting nine risk factors, including continuing education in early life, reducing hearing loss in mid-life, and reducing smoking in later life. As a member of the Russell Group, our research has an outstanding foundation with world-class research in all subject areas

A large-scale trial led by the University of Exeter has found that cognitive rehabilitation leads to people with dementia seeing satisfying progress in areas that enable them to maintain their functioning and independence. This stands in stark contrast to the posting from June 27, 2017 about a review suggesting that there was insufficient evidence to conclude that cognitive rehabilitation, as compared to no other treatment, led to better return to work, community integration or quality of life in adults with traumatic brain injury. Albeit this was a different population, questions remain as to what was considered cognitive rehabilitation, how it was implemented/ delivered, was it actively generalized/ translated into real world contexts, and did participants have the foundation (abstract thinking) to understand cognitive rehabilitation efforts in this review. The Exeter study certainly was geared to clients' needs, one of the components to ensure successful uptake of the cognitive rehabilitation efforts.
