Sentences with phrase «decreased volume of the hippocampus»

Not exact matches

A volume decrease in specific parts of the brain's hippocampus — long identified as a hub of mood and memory processing — was linked to bipolar disorder in a study led by researchers at The University of Texas Health Science Center at Houston (UTHealth).

There are genes that determine whether the same life event causes an increase or decrease in the volume of the hippocampus, and which therefore defines whether the stress is good or bad for our brain.

The volume of the hippocampus appears to decrease during the aging process, and this decrease might be related to the memory deficits that some older people experience.

And University of Pittsburgh researchers discovered that women who reported feeling high levels of stress over the course of 20 years had decreased volume in the right side of the hippocampus.

Researchers have found that BDNF levels decline progressively with age.10 Lommatzsch, M., et al. «The Impact of Age, Weight and Gender on BDNF Levels in Human Platelets and Plasma,» Neurobiology of Aging 26 (2005):... continue At the same time that BDNF levels decrease, the volume of the hippocampus (primary center for emotion and memory) also decreases.11 Erickson, K.L., et al. «Brain - Derived Neurotrophic Factor is Associated with Age - Related Decline in Hippocampal Volume, Journal of Neuroscience 30,... continue In fact, in some neurological diseases, such as Huntington's and Alzheimer's disease, BDNF levels are low or deficient.12 Laske, C., et al. «Decreased Brain - Derived Neurotrophic Factor (BDNF) and B - Thromboglobulin Blood Levels in Alzheimer's Disease,» Journal of... covolume of the hippocampus (primary center for emotion and memory) also decreases.11 Erickson, K.L., et al. «Brain - Derived Neurotrophic Factor is Associated with Age - Related Decline in Hippocampal Volume, Journal of Neuroscience 30,... continue In fact, in some neurological diseases, such as Huntington's and Alzheimer's disease, BDNF levels are low or deficient.12 Laske, C., et al. «Decreased Brain - Derived Neurotrophic Factor (BDNF) and B - Thromboglobulin Blood Levels in Alzheimer's Disease,» Journal of... coVolume, Journal of Neuroscience 30,... continue In fact, in some neurological diseases, such as Huntington's and Alzheimer's disease, BDNF levels are low or deficient.12 Laske, C., et al. «Decreased Brain - Derived Neurotrophic Factor (BDNF) and B - Thromboglobulin Blood Levels in Alzheimer's Disease,» Journal of... continue

Stress paradigms in rodent models have been associated with elevated anxiety and contrasting alterations in neuronal morphology in the hippocampus and amygdala, with dendritic atrophy observed in the hippocampus and increased dendritic arborization in the amygdala.12, 13 Developing rodents deprived of maternal nurturance show decreased hippocampal volume and altered stress reactivity.14 An epigenetic mechanism for this effect has been elaborated.15 Importantly, controlled trials that have randomized institutionalized toddlers to early therapeutic foster care vs institutionalization have documented the deleterious effects of early relative deprivation on cognitive outcomes.16

Specifically, we found that smaller hippocampus volumes and greater responses to sad faces in emotion reactivity regions predict increased depressive symptoms at the time of scan, whereas larger amygdala volumes, smaller insula volumes, and greater responses in emotion reactivity regions predict decreased emotion regulation skills.
