Social cognition in adult survivors of brain tumors: studying the relationship between theory of mind and quality of life

OBJECTIVE

The present study is the first to examine theory of mind (ToM) sequelae in a sample of adult survivors of primary brain tumors, and to investigate the assumed relationship between ToM and health-related quality of life (HRQoL).

METHOD

Participants were 40 long-term adult survivors of primary brain tumors and 40 matched healthy controls. They completed ToM tests (Faux-Pas test and Advanced ToM task) and two questionnaires assessing HRQoL (36-Item Short-Form Health Survey and EORTC QLQ-C30/QLQ-BN20). Their relatives also completed an observer-rated version of the SF-36 questionnaire.

RESULTS

Survivors performed worse than controls only on the Advanced ToM task. Overall, patients and caregivers reported more problems than healthy controls and their relatives regarding both global HRQoL and its social/emotional aspects. No relationship was found between ToM and HRQoL scores.

CONCLUSION

Adult survivors of primary brain tumors may exhibit ToM deficits several years after treatment and report more problems on social/emotional HRQoL components. Our findings highlight the need to consider these late effects in survivors' long-term follow-up, even if the clinical involvement of ToM deficits still needs to be elucidated. The assessment of ToM deficits and their potential impact on survivors' everyday life is thoroughly discussed.

Treating social cognition impairment with the online therapy 'SoCoBo': A randomized controlled trial including traumatic brain injury patients

OBJECTIVE

Acquired brain injuries (ABIs), such as traumatic brain injuries (TBIs), often entail impairments of general cognition (e.g., memory, attention or executive functions) and social cognition (e.g. emotion recognition, theory of mind [ToM], social problem-solving). The availability of fully computerized interventions targeting sociocognitive deficits specifically in neurologically impaired patients is extremely limited. Therefore, the Treatment Program for Deficits in Social Cognition and Social Competencies of the Ruhr University Bochum (SoCoBo), a fully computerized online therapy designed for ABI patients was evaluated in a randomized controlled trial involving TBI patients.

METHOD

Sixty-four patients with TBI were randomly assigned to two groups with 43 patients fully completing either SoCoBo (N = 27) or a commercially available computerized program for cognitive rehabilitation (RehaCom®, N = 16). All participants underwent comprehensive pre-post online neuropsychological assessment and worked with their respective rehabilitation programs for four days a week during a scheduled period of 12 weeks.

RESULTS

After treatment, the SoCoBo group, but not the RehaCom® group showed significant improvements in facial emotion recognition and self-rated empathy. Moreover, in the SoCoBo group, an increase in empathy was also associated with increased life satisfaction after treatment. There were no improvements in ToM and social problem-solving. Furthermore, general cognition did not improve in any of the groups.

CONCLUSIONS

SoCoBo represents an effective new online therapy for the amelioration of deficits in key domains of social cognition. Its implementation in clinical practice will serve as a meaningful addition to the existing fully computerized approaches specifically in neurological patient groups.

INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury, Part IV: Cognitive-Communication and Social Cognition Disorders

INTRODUCTION

Moderate to severe traumatic brain injury causes significant cognitive impairments, including impairments in social cognition, the ability to recognize others' emotions, and infer others' thoughts. These cognitive impairments can have profound negative effects on communication functions, resulting in a cognitive-communication disorder. Cognitive-communication disorders can significantly limit a person's ability to socialize, work, and study, and thus are critical targets for intervention. This article presents the updated INCOG 2.0 recommendations for management of cognitive-communication disorders. As social cognition is central to cognitive-communication disorders, this update includes interventions for social cognition.

METHODS

An expert panel of clinicians/researchers reviewed evidence published since 2014 and developed updated recommendations for interventions for cognitive-communication and social cognition disorders, a decision-making algorithm tool, and an audit tool for review of clinical practice.

RESULTS

Since INCOG 2014, there has been significant growth in cognitive-communication interventions and emergence of social cognition rehabilitation research. INCOG 2.0 has 9 recommendations, including 5 updated INCOG 2014 recommendations, and 4 new recommendations addressing cultural competence training, group interventions, telerehabilitation, and management of social cognition disorders. Cognitive-communication disorders should be individualized, goal- and outcome-oriented, and appropriate to the context in which the person lives and incorporate social communication and communication partner training. Group therapy and telerehabilitation are recommended to improve social communication. Augmentative and alternative communication (AAC) should be offered to the person with severe communication disability and their communication partners should also be trained to interact using AAC. Social cognition should be assessed and treated, with a focus on personally relevant contexts and outcomes.

CONCLUSIONS

The INCOG 2.0 recommendations reflect new evidence for treatment of cognitive-communication disorders, particularly social interactions, communication partner training, group treatments to improve social communication, and telehealth delivery. Evidence is emerging for the rehabilitation of social cognition; however, the impact on participation outcomes needs further research.

IMPAIRED VISUAL EMOTION RECOGNITION AFTER MINOR ISCHEMIC STROKE

OBJECTIVE

To assess the prevalence of impaired visual emotion recognition in patients who have suffered a minor ischemic stroke in the subacute phase and to determine associated factors of impaired visual emotion recognition.

DESIGN

A prospective observational study.

SETTING

Stroke-unit of a teaching hospital.

PARTICIPANTS

112 patients with minor ischemic stroke.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Patients with minor stroke underwent a neuropsychological assessment in the sub-acute phase for visual emotion recognition by the Ekman 60 Faces Test and for general cognition. Univariable linear regression analyses were performed to identify associated factors of emotion recognition impairment.

RESULTS

In 112 minor stroke patients we found a prevalence of 25% of impaired visual emotion recognition. This was significantly correlated with impaired general cognition. Nevertheless 10.9% of patients with normal general cognition still had impaired emotion recognition. Mood was negatively associated. Stroke localization, hemisphere side and gender were not associated.

CONCLUSION

Impaired visual emotion recognition is found in about a quarter of patients with minor ischemic stroke.

Neuropsychiatric Disorders, Emotional Disturbances, and Their Associations with HIV-Associated Neurocognitive Disorder

The current chapter provides a critical and narrative review of recent research on the neuropsychiatric disorders, emotional disturbances, and their associations with neurocognitive functioning in people living with HIV infection. We review a range of neuropsychiatric disorders including depression and anxiety disorders, but also emotional disturbances, which can be partly distinguished from depression and anxiety (apathy, alexithymia, and emotional processing impairment). While reviewing the research into the neuropsychiatric disorders and HIV-associated neurocognitive disorders, we also cover the questions of self-reported cognitive symptoms evaluation and interpretation. The chapter includes research on the role of coping skills, perceived stress and response to stressful life events, and connections to neurocognitive impairment in people living with HIV. Promising non-pharmacological interventions are highlighted. The chapter concludes with the clinical implications on how to best consider neuropsychiatric disorders and cognitive symptoms for the diagnosis of HIV-associated neurocognitive disorders, as well as future research directions.

Impairment of sociocognitive functions in patients with brain tumours

The ability to decode mental states and to come up with effective solutions for interpersonal problems aids successful initiation and maintenance of social interactions and contributes to participation and mental health. Since these abilities of social cognition are challenged in highly demanding situations, such as diagnosis and treatment of a life-threatening illness, this article reviews the literature on emotion recognition, empathy, Theory of Mind and socially skilled behaviour in brain tumour patients. The data available suggest that patients are affected by a slight but consistent impairment of emotion recognition, empathy and Theory of Mind before and immediately after brain tumour treatment, with the degree of impairment being influenced by tumour histology and localization. Impairments mostly decrease a few months after surgery due to assumed neuroplasticity. Future research may address more complex sociocognitive functions, such as social problem solving, and may investigate to which degree sociocognitive difficulties act as risk factors for poor or failed reintegration into occupational and social life following successful brain tumour treatment.

Interpretation of non-verbal cues by people with and without TBI: understanding relationship intentions

BACKGROUND

Although long-term social challenges following traumatic brain injury (TBI) are well documented, the challenges of establishing new relationships following TBI are less understood.

AIMS

To examine how the type of non-verbal cues produced by an unfamiliar communication partner impacts feelings of relationship closeness by people with and without TBI.

METHODS & PROCEDURES

In this quasi-experimental comparative mixed-group design, participants included 12 male heterosexual adults with moderate/severe TBI and 10 typical comparison peers. An adaptation of the Relationship Closeness Induction Task (RCIT), a 29-item questionnaire, was completed by all participants to induce relationship closeness through reciprocal self-disclosure during conversation. Participants completed the RCIT three separate times in counterbalanced order. Conversational partners for the RCIT were three female actors trained to convey similar verbal answers to the RCIT questions, but to produce different non-verbal cues: solicitation (i.e., flirting), neutral and rejecting. Following each conversation, the participants completed a 10-item Likert-type questionnaire about the experience.

OUTCOMES & RESULTS

Between- and within-group non-parametric statistical analysis of Likert questions showed non-significant differences between the two participant groups such that both groups consistently rated the female actor who used flirting non-verbal cues higher than the actor who used rejecting non-verbal cues.

CONCLUSIONS & IMPLICATIONS

These results suggest a small sample of heterosexual males with TBI interpret non-verbal relationship cues in real-time conversations with unfamiliar partners as well as comparison peers. Clinical implications include the need to consider real-time conversation in assessment and treatment planning for social communication goals related to cognitive-communication impairment.

Treatment of social cognition impairments in patients with traumatic brain injury: a critical review

Objective: The aim of this study is to review published research on treatment of social cognition impairments in patients with traumatic brain injury (TBI).Methods: Following the PRISMA guidelines, a PubMed literature search was conducted, followed by a manual search in recently published papers. Main criteria for selection were that patients had sustained a TBI, and that social cognition was the main target of treatment. A total of 16 papers and three reviews were selected and included in the present review.Results: Five studies (including three randomized controlled trials (RCT)) addressed facial affect recognition, one study specifically addressed emotional prosody, two RCTs used a combination of treatment strategies addressing social perception deficits. Six studies, including two RCTs, addressed social communication skills or theory of mind. Finally, two RCTs reported the effectiveness of a more global approach, addressing multiple domains of social cognition, such as emotion perception, social skills training, and theory of mind.Discussion/conclusion: Although there has been much less research on treatment of social cognition in patients with TBI as compared with psychiatric conditions, the findings reported in the present review are encouraging. Further multicenter large-scale RCTs are needed, with special emphasis on the generalization of treatment effects to social skills in everyday life.
