Sentences with phrase «higher hippocampal volumes»

Not exact matches

Of all four groups studied, only those at high genetic risk for Alzheimer's who did not exercise experienced a decrease in hippocampal volume (3 %) over the 18 - month period.

Lower intakes of nutrient - dense foods and higher intakes of unhealthy foods are each independently associated with smaller left hippocampal volume.

Luby et al. (2013) and Noble et al. (2012a) find no significant correlations between parental education (measured as the average or highest level of education of any parents or guardians living in the home) and hippocampal volumes.

While animal data would suggest that institutional rearing would lead to reduced hippocampal volume, some investigators have suggested that such effects may not become evident in humans until later in life.18 Consistent with this, decreased hippocampal volumes have been found in numerous studies of adults who experienced high levels of childhood stress / trauma.19, 20 In spite of this hypothesized delayed hippocampal effect, a positive impact of early supportive parenting on hippocampal development has been detected as early as school age.21

Also, people with low self - esteem and depression react with more stress in several stressful situations, secretion of cortisol in their blood is higher and their hippocampal volume is reduced (Orth, Robins, Widaman, & Conger, 2014).

Increased volume in this brain region is associated with more optimal development of a number of psychosocial factors (e.g., stress reactivity).15 Links between early responsive parenting and increased volume in the hippocampal region also suggest that the early developmental period is an important time to facilitate responsive parenting practices, especially in high risk families, in order to enhance the parent - child relationship.

Research shows it has the potential to promote normal developmental trajectories for high - risk children, such as those from low - income backgrounds and / or those with very premature births.13 In contrast, unresponsive parenting may jeopardize children's development, particularly those at higher risk for developmental problems.14 The critical importance of responsive parenting is highlighted by recent evidence identifying links between high levels of early responsive parenting and larger hippocampal volumes for normally developing preschool aged children.
