Abstract Previous research has established important developmental changes in sleep and memory during early childhood. These changes have been linked separately to brain development, yet few studies have explored their interrelations during this developmental period. The goal of this report was to explore these associations in 200 (100 female) typically developing 4- to 8-year-old children. We examined whether habitual sleep patterns (24-h sleep duration, nap status) were related to children’s performance on a source memory task and hippocampal subfield volumes. Results revealed that, across all participants, after controlling for age, habitual sleep duration was positively related to source memory performance. In addition, in younger (4–6 years, n = 67), but not older (6–8 years, n = 70) children, habitual sleep duration was related to hippocampal head subfield volume (CA2-4/DG). Moreover, within younger children, volume of hippocampal subfields varied as a function of nap status; children who were still napping (n = 28) had larger CA1 volumes in the body compared to children who had transitioned out of napping (n = 39). Together, these findings are consistent with the hypothesis that habitually napping children may have more immature cognitive networks, as indexed by hippocampal integrity. Furthermore, these results shed additional light on why sleep is important during early childhood, a period of substantial brain development.

Objective: This study aimed to characterize clusters of children based on ADHD and sensory over-responsivity (SOR) symptoms, and to compare their markers. Method: Parents of 922 infants completed the Infant–Toddler Social and Emotional Assessment (ITSEA) Sensory Sensitivity, Attention, and Activity/Impulsivity scales at three time points during early childhood and the Child Behavior Checklist (CBCL) and SensOR inventory during elementary school age. Results: Four school-age clusters emerged from the CBCL ADHD and SensOR scores: (a) elevated SOR symptoms only ( n = 35); (b) elevated ADHD symptoms only ( n = 38); (c) elevated ADHD and SOR symptoms (ADHD + S, n = 35); and (d) low ADHD and SOR symptoms ( n = 814). The SOR and ADHD + S clusters had higher early Sensitivity scores than the ADHD and Low clusters. The ADHD and ADHD + S clusters differed from the SOR and Low clusters in their early Attention and Activity/Impulsivity scores. Conclusion: SOR and ADHD symptoms occur independently and consistently over time.
