#NPsychPick of the Month

Abstract

This discussion paper presents reflections from a group of clinical, forensic and neuropsychologists on their clinical caseloads in brain injury rehabilitation services at Cygnet Healthcare. These services specialise in working with people with coexisting mental health or behavioural difficulties where the work involves frequent staff discussions on interpreting an individual’s behaviour, considering its functions and whether it is part of an involuntary neuro-psychological disorder related to their brain injury, specifically the Frontal Lobe Paradox. Through consideration of six patients, the cognitive mechanisms that may relate to, or underlie apparent Frontal Lobe Paradox were highlighted. Several additional reasons were found to explain why people might show this paradox, including testing conditions, slowed processing, reduced attention, disinhibition, self-monitoring problems, and premorbid difficulties. The authors also discuss interventions, which could be used to support these individuals, with the aim of broadening clinical understanding and discussion surrounding the causes of, and treatment approaches for individuals presenting with potential Frontal Lobe Paradox.

Impact of Covid-19 lockdown on the mood, behaviour, and social activities of people with brain injury in the UK: Results of a survey of brain injury professionals’ reports

#NPsychTeamResearch

 

Abstract

The Covid-19 related lockdown of March–June 2020 in the United Kingdom (UK) may have negatively affected mood and behaviour of people with brain injuries. Conversely, there may have been beneficial effects due to reduced demand on cognition and emotional regulation. In this online survey study, care coordinators (n=19) assessed the consequences of lockdown on 130 individuals with ABI (range 3–29 clients per care co-ordinator; 10–65years+; and mostly living in residential care). The majority of reports were of no change to mood, behaviour, or social functioning (105 ratings). However, respondents reported that 88 (68 per cent) clients presented with changes: 63 clients (48 per cent) had lower mood, higher distress, and agitation, and were less engaged in usual activities; while 25 clients (19 per cent) were reported to have improved. Moreover, 13/19 (68 per cent) of respondents reported increased vulnerabilities in their clients, and 5/19 (26 per cent) reported online exploitation, controlling behaviour from partner and financial scams. These data present a mixed picture of how the first national lockdown affected people with ABI.

Glial Fibrillary Acidic Protein as a Marker for Mild Traumatic Brain Injury

What’s the science?

Millions of cases of mild traumatic brain injury occur each year. Computed tomography (CT) scans are used to detect mild traumatic brain injury, and MRI can be used to detect subtle changes in the brain like neuron axonal injury, however these are costly and time-consuming. There is a need for a blood-based biomarker that can detect milder forms of brain injury to ensure proper treatment for these patients. This week in Neurology, Ori and colleagues test whether blood-based biomarkers are associated with neuroimaging changes (on CT and MRI scans) and can successfully detect mild traumatic brain injury.

How did they do it?

Four blood-based biomarkers have previously been associated with brain changes that follow traumatic brain injury of varying severities: Tau (a neuronal injury marker), Glial Fibrillary Acidic protein, ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) and neurofilament light. The authors aimed to assess whether any of these biomarkers would be elevated in mild traumatic brain injury and whether they were also associated with subtle structural changes shown on an MRI scan (using diffusion tensor imaging). A group of 277 patients seeking care for a mild brain injury were enrolled in the study. Blood was drawn to measure plasma concentrations of biomarkers and CT and MRI scans were performed within 48 hours of the injury. A control group of 49 healthy participants (with well-matched demographics) was included for comparison.
What did they find?

Glial Fibrillary Acidic protein, Tau and Neurofilament light were all higher in patients with mild traumatic brain injury compared to controls. Glial Fibrillary Acidic protein was the best predictor of mild traumatic brain injury (diagnosis). When patients with mild brain injury were stratified into those with and without changes on their CT scans, Glial Fibrillary Acidic protein, Tau and neurofilament light concentrations were all higher in patients with detectable changes. However, Glial Fibrillary Acidic protein concentration was the only biomarker that significantly predicted trauma-related CT scan changes. Glial Fibrillary Acidic protein, Tau and Neurofilament light all predicted structural MRI changes, however Glial Fibrillary Acidic protein was the strongest predictor of structural MRI changes related to mile traumatic brain injury.

What’s the impact?

This is the first study to examine whether blood-based biomarkers can be used to detect mild traumatic brain injury. Glial Fibrillary Acidic protein concentration is a sensitive predictor of mild traumatic brain injury and is also closely associated with neuroimaging changes. CT and MRI scans are expensive and time-consuming, so having methods to detect the presence and severity of brain injury early on is important for proper and effective treatment.
