Sentences with phrase «reduced brain volumes»

Physical punishment is associated with a range of mental health problems in children, youth and adults, including depression, unhappiness, anxiety, feelings of hopelessness, use of drugs and alcohol, and general psychological maladjustment.26 — 29 These relationships may be mediated by disruptions in parent — child attachment resulting from pain inflicted by a caregiver, 30,31 by increased levels of cortisol32 or by chemical disruption of the brain's mechanism for regulating stress.33 Researchers are also finding that physical punishment is linked to slower cognitive development and adversely affects academic achievement.34 These findings come from large longitudinal studies that control for a wide range of potential confounders.35 Intriguing results are now emerging from neuroimaging studies, which suggest that physical punishment may reduce the volume of the brain's grey matter in areas associated with performance on the Wechsler Adult Intelligence Scale, third edition (WAIS - III).36 In addition, physical punishment can cause alterations in the dopaminergic regions associated with vulnerability to the abuse of drugs and alcohol.37

Because of the effective use of the ketogenic diet in reducing seizures (see above), it has been suggested that it may also improve the clinical status in brain injury, especially by reducing the incidence of long - term consequences, such as epilepsy.79 Positive effects of a ketogenic diet have also been reported in reducing the cortical contusion volume in an age - dependent manner in an animal model of cortical injury, which is related to the maturation - dependent variability in brain ketone metabolism.92 These findings were also supported by the demonstration that a ketogenic diet reduced post-traumatic cognitive and motor function impairment, at least in a rat model.93
