Objective:

The current study examined attention among females with a fragile X premutation allele (PM). An estimated 1.5 million people in the US have a PM, defined as 55-200 expanded CGG repeats in the X-linked FMR1 gene. There are female-specific findings among adults with a PM, including higher rates of self-reported mental health disorders, including attention problems. Both women and girls with a PM have higher than expected rates of reported attention difficulties but findings on cognitive measures of attention are inconclusive or lacking. The aims of the current study were to examine: 1) whether attention difficulties are present in girls with a PM compared to girls without a PM; and 2) whether there is a worsening of attentional skills over time in females with a PM.

Participants and Methods:

Girls ages 8 to 12 were identified with a PM (n = 12) or without a PM (n = 15) through routine prenatal screening. Women with a PM (n = 16) ages 25 to 50 were recruited through a pre-existing database. All participants completed the 2-subtest Wechsler Abbreviated Scale Intelligence-II, the Digit Span subtest (from the Wechsler Intelligence Scale for Children-V or the Wechsler Adult Intelligence Scale-IV), and the Verbal Attention subtest from the Woodcock Johnson-IV Test of Cognitive Abilities. The normative scores of all participants’ Full Scale Intelligence Quotient (FSIQ), Digit Span score, and Verbal Attention score were transformed to z-scores and difference scores were calculated between 1) FSIQ and Digit Span and 2) FSIQ and Verbal Attention. Independent t-tests comparing girls with and without a PM and comparing girls with a PM versus women with a PM were performed on Digit Span scaled scores, Verbal Attention standard scores, and the calculated difference scores.

Results:

Girls with a PM performed significantly lower on the Verbal Attention subtest (M = 104.92, SD = 10.85) compared to girls without a PM (M = 112.20, SD = 9.94; t = -1.82, p = 0.041), though no significant differences were observed for Digit Span (carriers M = 11.08, SD = 2.02; noncarriers M = 11.53, SD = 3.02), or for the difference scores of the FSIQ-Digit Span (carriers M = .49, SD = 1.09; noncarriers M = .76, SD = 1.09) and FSIQ-Verbal Attention (carriers M = .53, SD= 1.11; noncarriers M = .45, SD = 1.09). There were no significant differences between girls and women with a PM for any of the measures.

Conclusions:

Our findings did not show evidence for significantly worse attention in girls with a PM compared to girls without a PM, with the exception of one attention task, suggesting that attention problems may be more subtle than previous studies have indicated. Additionally, despite reported attention difficulties in women with a PM, our study found no evidence of worsening attentional performance in adulthood. Future studies observing both reported measures and sensitive task-based measures of attention in larger sample sizes are necessary to understand the attentional trajectory across the lifespan of females with a PM.
