Is social functioning in older age patients with bipolar disorder associated with affective and/or non-affective cognition?

OBJECTIVES

Previous research showed impairments in non-affective cognition, affective cognition, and social functioning in adult patients with bipolar disorder (BD). Only 37% of adult BD patients recovers in social functioning, and both aspects of cognition are important constructs of influence. The role of affective cognition in older age bipolar disorder (OABD) patients is still unclear. Therefore, the aim of our study was to examine the separate and combined effects of affective cognition and non-affective cognition on social functioning.

METHODS

The current study included 60 euthymic patients (aged >60) of the Dutch Older Bipolar Study. Affective cognition was measured by Theory of Mind and Emotion Recognition. Non-affective cognition was assessed through the measurements of attention, learning and memory, and executive functioning. Social functioning was examined through global social functioning, social participation, and meaningful contacts. The research questions were tested with linear and ordinal regression analyses.

RESULTS

Results showed a positive association of all non-affective cognitive domains with global social functioning. Associations between affective cognition and social functioning were non-significant. Results did show an interaction between non-affective and affective cognition.

CONCLUSIONS

Associations between non-affective cognition and social functioning were confirmed, associations between affective cognition and social function were not found. For generalizability, studies with a greater sample size are needed. Conducting additional research about OABD patients and affective cognition is important. It may lead to more insight in impairment and guide tailored treatment that focusses more on all aspects of recovery and the needs of OABD patients.

Psychometric Properties and Validation of the EMOTICOM Test Battery in a Healthy Danish Population

Disruptions in hot cognition, i.e., the processing of emotionally salient information, are prevalent in most neuropsychiatric disorders and constitute a potential treatment target. EMOTICOM is the first comprehensive neuropsychological test battery developed specifically to assess hot cognition. The aim of the study was to validate and establish a Danish language version and reference data for the EMOTICOM test battery. To evaluate the psychometric properties of 11 EMOTICOM tasks, we collected data from 100 healthy Danish participants (50 males, 50 females) including retest data from 49 participants. We assessed test-retest reliability, floor and ceiling effects, task-intercorrelations, and correlations between task performance and relevant demographic and descriptive factors. We found that test-retest reliability varied from poor to excellent while some tasks exhibited floor or ceiling effects. Intercorrelations among EMOTICOM task outcomes were low, indicating that the tasks capture different cognitive constructs. EMOTICOM task performance was largely independent of age, sex, education, and IQ as well as current mood, personality, and self-reported motivation and diligence during task completion. Overall, many of the EMOTICOM tasks were found to be useful and objective measures of hot cognition although select tasks may benefit from modifications to avoid floor and ceiling effects in healthy individuals.

Affective cognition in bipolar disorder: A systematic review by the ISBD targeting cognition task force

BACKGROUND

Impairments in affective cognition are part of the neurocognitive profile and possible treatment targets in bipolar disorder (BD), but the findings are heterogeneous. The International Society of Bipolar Disorder (ISBD) Targeting Cognition Task Force conducted a systematic review to (i) identify the most consistent findings in affective cognition in BD, and (ii) provide suggestions for affective cognitive domains for future study and meta-analyses.

METHODS

The review included original studies reporting behavioral measures of affective cognition in BD patients vs controls following the procedures of the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) statement. Searches were conducted on PubMed/MEDLINE, EMBASE, and PsychInfo from inception until November 2018.

RESULTS

A total of 106 articles were included (of which nine included data for several affective domains); 41 studies assessed emotional face processing; 23 studies investigated reactivity to emotional words and images; 3 investigated explicit emotion regulation; 17 assessed implicit emotion regulation; 31 assessed reward processing and affective decision making. In general, findings were inconsistent. The most consistent findings were trait-related difficulties in facial emotion recognition and implicit emotion regulation, and impairments in reward processing and affective decision making during mood episodes. Studies using eye-tracking and facial emotion analysis revealed subtle trait-related abnormalities in emotional reactivity.

CONCLUSION

The ISBD Task Force recommends facial expression recognition, implicit emotion regulation, and reward processing as domains for future research and meta-analyses. An important step to aid comparability between studies in the field would be to reach consensus on an affective cognition test battery for BD.

Visual Working Memory for Faces and Facial Expressions as a Useful "Tool" for Understanding Social and Affective Cognition

Visual working memory (VWM) is one of the most investigated cognitive systems functioning as a hub between low- and high-level processes. Remarkably, its role in human cognitive architecture makes it a stage of crucial importance for the study of socio-affective cognition, also in relation with psychopathology such as anxiety. Among socio-affective stimuli, faces occupy a place of first importance. How faces and facial expressions are encoded and maintained in VWM is the focus of this review. Within the main theoretical VWM models, we will review research comparing VWM representations of faces and of other classes of stimuli. We will further present previous work investigating if and how both static (i.e., ethnicity, trustworthiness and identity) and changeable (i.e., facial expressions) facial features are represented in VWM. Finally, we will examine research showing qualitative differences in VWM for face representations as a function of psychopathology and personality traits. The findings that we will review are not always coherent with each other, and for this reason we will highlight the main methodological differences as the main source of inconsistency. Finally, we will provide some suggestions for future research in this field in order to foster our understanding of representation of faces in VWM and its potential role in supporting socio-affective cognition.

[The features of emotional processing in patients with depressive disorders]

AIM

To study neurocognitive symptoms in depressive disorders with the designation of their brain and psychological mechanisms.

MATERIAL AND METHODS

Thirty-three patients diagnosed with depression and 33 healthy controls were studied using standardized neuropsychological tests and tests comprising emotiogenic stimuli.

RESULTS

A neurocognitive deficit in patients with depression manifested as changes in speed of emotional processing and some cognitive functions. These patients demonstrate decreased attention to negative stimuli combined with decreased attention to positive stimuli.

CONCLUSION

The abnormal processes of 'hot' cognition in patients with depressive disorders conceptualize such a core symptom of depression as anhedonia, which is a probable endophenotype of depression.
