Tóm tắt

AbstractTo identify possible factors affecting the psychological impact of pre‐symptomatic testing for spinocerebellar ataxia type 2 (SCA2) and familial amyloid polyneuropathy (FAP ATTRV30M), we studied (1) the effect of previous experience with the disease in the family, (2) kinship with the closest affected relative and (3) gender of affected parent, when adapting to test results; as well as (4) differences in the course of psychological wellbeing in 63 subjects (28 at‐risk for FAP ATTRV30M, and 35 at risk for SCA2), who pursued predictive testing for these diseases, in Cuba and in Portugal. Our research shows that individuals with little or no experience with the disease in their family exhibited more anxiety; at‐risk subjects for SCA2 or FAP ATTRV30M who had a first degree relative with the disease showed lower levels of anxiety and depression during pre‐symptomatic testing. Also those with an affected mother had lower levels of depression, either immediately, or one year after receipt of test results. Adaptation to pre‐symptomatic testing results differed for subjects at‐risk for the two different conditions. Unlike the FAP ATTRV30M families, carriers for SCA2 reported pathological levels of depression immediately after‐testing (3 weeks), although those levels had returned to normal levels at 6 months. Subjects at‐risk for FAP ATTRV30M tended to have less anxiety than those tested for SCA2, at the one‐year follow‐up. Overall, depression levels improved over time, while anxiety remained more constant. A longer awareness of the disease in the family, closer kinship, and a transmitting mother all lessened the impact of pre‐symptomatic testing, as expressed by the post‐test levels of anxiety and depression.
