Insights
In adults with Huntington's disease, better inhibitory control/attention skills were linked to improved coping strategies, which in turn reduced anxiety and depression symptoms. Working memory did not show similar associations.
Area of Science:
- Neuroscience
- Psychology
- Genetics
Background:
- Huntington's disease (HD) is a neurodegenerative disorder causing significant stress.
- Anxiety and depression are common neuropsychiatric symptoms in HD patients.
- Executive functions and coping skills are potential factors influencing these symptoms.
Purpose of the Study:
- To investigate the relationship between executive function (inhibitory control/attention, working memory), coping strategies, and symptoms of anxiety and depression in adults with HD.
- To identify specific executive function and coping mechanisms that may mitigate psychological distress in HD.
Main Methods:
- Adults with HD completed assessments of executive function (NIH Toolbox), coping strategies, and anxiety/depression symptoms.
- Path analyses were employed to examine direct and indirect associations between executive functioning, coping, and symptomology.
Main Results:
- In a subsample with adequate executive function, higher inhibitory control/attention was associated with increased use of secondary coping strategies (acceptance, reappraisal).
- Greater use of these secondary coping skills correlated with reduced symptoms of anxiety and depression.
- No significant associations were found for working memory, coping, and symptoms in the full sample or subsample.
Conclusions:
- Enhancing executive function, particularly inhibitory control/attention, may be a viable intervention target.
- Interventions aimed at improving coping skills, such as acceptance and reappraisal, could help manage anxiety and depression in HD.
- Future research should explore targeted interventions for HD patients.
Objective:
Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterized by neuropsychiatric symptoms (e.g., anxiety and depression), where individuals suffer high levels of stress from the social, physical, and cognitive burden of the disease. The present study examined two factors associated with increased risk for symptoms of anxiety and depression: executive function skills (inhibitory control/attention and working memory) and skills to cope with stress.
Method:
Adults with HD completed the NIH Toolbox measures of inhibitory control/attention and working memory, as well as self-report measures of coping with HD-related stress and symptoms of anxiety and depression. Path analyses were used to test direct and indirect associations among the subtypes of executive functioning, coping, and symptoms.
Results:
No significant associations were found in the full sample (n = 47), due to a significant portion of the sample with very low executive function abilities. Additional analyses were conducted on a subset of the sample (participants in the top three quartiles on both measures of executive functioning, n = 32). Significant indirect associations emerged among inhibitory control/attention skills, secondary control coping (e.g., acceptance and reappraisal), and symptoms of anxiety and depression in the subsample. Higher inhibitory control/attention skills were associated with greater use of secondary control coping, and greater use of these coping skills was related to lower symptoms of anxiety and depression. No direct or indirect associations were found among working memory skills, coping, and symptoms of anxiety and depression.
Conclusions:
Implications for interventions to enhance executive function and coping skills in adults with HD are highlighted. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
