Behavioral phenotype in childhood type of dystrophia myotonica

Dyslexia and cognitive impairment in adult patients with myotonic dystrophy type 1: a clinical prospective analysis

“…Cognitive impairment is a well elaborated finding in congenital and early-onset DM1 patients. Several studies explored the intelligence level for congenital and juvenile DM1, in the majority of cases scoring a below-average IQ [14,34]. The average IQ in our adult DM1 cohort counts in the lower normal range with 86.1, which is consistent with other study results reporting an average IQ of 82.6 in adult DM1 patients [28].…”

Psychiatric and cognitive phenotype of childhood myotonic dystrophy type 1

“…We did not find any individual with ASD in our sample, which confirms most of the other published studies, 4,5,7,15 with the exception of Ekström et al 6 . who described a high rate (35%) of ASD in childhood DM1.…”

Delusional and psychotic disorders in juvenile myotonic dystrophy type‐1

“…This finding is partly a replication of findings of earlier studies mentioned above on the psychiatric diagnoses in children with juvenile DM. In contrast with these studies (e.g., 25% of anxiety disorders in Steyaert et al, 2000) we did not encounter any patient with an anxiety disorder. This corresponds to the general clinical finding that most children with anxiety disorders do not have an anxiety disorder in adulthood [Rutter, 1994].…”
