Subjective Cognitive Concerns and Attitudes toward Genetic Testing Are Associated with Depressive Symptoms and Quality of Life after Genetic Testing for the Cerebral Cavernous Malformation Common Hispanic Mutation (CCM1).

ABSTRACT: Purpose:This study aimed to characterize mood and quality of life and to examine the associations of these areas with subjective cognitive concerns and attitudes toward genetic testing for the Common Hispanic Mutation, a gene that has been associated with increased risk for CCM1. Method:Fifty-four adults with previous genetic testing for the Common Hispanic Mutation completed a mail survey that included assessments of the above identified areas. Results:Self-reported depressive symptoms and quality of life did not differ between those with positive and negative genetic test results. The negative group expressed a more favorable attitude toward genetic testing (p < 0.001). There was a trend toward more subjective cognitive concerns in the positive group (p = 0.06). Using generalized linear regression, more subjective cognitive concerns were associated with poorer quality of life and more depressive symptoms (p < 0.001). Poorer attitude toward genetic testing was also associated with poorer quality of life (p < 0.05). Conclusions:Subjective cognitive concerns and negative attitudes toward genetic testing may influence emotional well-being after genetic testing for the Common Hispanic Mutation. Additional research is needed that uses objective neuropsychological measures to understand the associations of subjective cognitive concerns, emotional well-being, and cognitive test performance in individuals with CCM1. There is also a need for research that focuses on protective factors and resiliency following genetic testing for CCM1 and the development of mental health interventions to preempt psychosocial difficulties.

Project description:Cerebral cavernous malformations (CCM) are enlarged vascular lesions affecting 0.1-0.5% of the population worldwide and causing hemorrhagic strokes, seizures, and neurological deficits. Familial CCM type 1 (CCM1) is an autosomal dominant disease caused by mutations in the Krev Interaction Trapped 1 (KRIT1/CCM1) gene, and is characterized by multiple brain lesions whose number and size increase with age. The number of lesions varies widely for unknown reasons, even among carriers of similar ages with the same mutation. The purpose of this study was to investigate whether cardiovascular (CV) risk factors influence potential markers of familial CCM1 disease severity, such as lesion count and history of intracerebral hemorrhage.We analyzed baseline data from 185 Hispanic subjects, enrolled in the Brain Vascular Malformation Consortium study between June 2010 and March 2013. All subjects were carriers of the founder Q455X 'Common Hispanic Mutation' (CHM) in the KRIT1 gene, and had a clinical diagnosis of CCM or had an affected first- or second-degree relative with CCM. We performed a cross-sectional study, collecting detailed clinical information of CCM1-CHM subjects and cerebral susceptibility-weighted magnetic resonance imaging to assess lesion count. Linear or logistic regression analysis of log-lesion count or history of intracerebral hemorrhage and CV risk factors (age, gender, obesity, diabetes, hypertension, hyperlipidemia and smoking status) and related quantitative traits (body mass index, glycosylated hemoglobin levels, blood pressure, lipids levels and pack-years of cigarette smoking) was performed accommodating familial clustering.CCM1-CHM subjects were mainly female (63.8%) and symptomatic at presentation (63.2%). Lesion count was highly variable (mean ± SD: 57.7 ± 110.6; range: 0-713); 90% of CCM1-CHM subjects had multiple lesions at enrollment. Age (p < 0.001) was positively correlated with lesion count and male gender (p = 0.035) was associated with a greater number of lesions. Obesity (p = 0.001) and higher body mass index (p = 0.002) were associated with fewer lesions. No association with hypertension was detected, however, systolic blood pressure (p = 0.002) was associated with fewer lesions. No significant association with lesion count was observed for diabetes, hyperlipidemia, smoking status or for related quantitative traits. History of intracerebral hemorrhage was not significantly associated with any CV risk factors, however, we found borderline associations of hemorrhage with obesity (p = 0.062), systolic blood pressure (p = 0.083) and pack-years of cigarette smoking (p = 0.055). After correction for multiple testing, age and obesity remained significantly associated with lesion count in CCM1-CHM subjects.These results suggest that several CV risk factors explain some of the variability in lesion count in Hispanic CCM1-CHM subjects. Although age, gender, obesity, body mass index and systolic blood pressure may influence familial CCM1 disease severity, further longitudinal studies in larger sample sizes are essential to confirm these findings.
