Childhood Maltreatment: Altered Network Centrality of Cingulate, Precuneus, Temporal Pole and Insula

Abstract

Background
Childhood abuse is a major risk factor for psychopathology. Previous studies have identified brain differences in maltreated individuals but have not focused on potential differences in network architecture….

Results
Marked differences in centrality (connectedness, ‘importance’) were observed in a handful of cortical regions. Left anterior cingulate had the second highest number of connections (degree centrality) and was a component of the ‘rich club’ in the control network but ranked low in connectedness (106th of 112 nodes) in the network derived from maltreated-subjects (p<0.01). Conversely, right precuneus and right anterior insula ranked first and 15th in degree centrality in the maltreated network versus 90th (p=0.01) and 105th (p<0.03) in the control network.
Conclusions

Maltreatment was associated with decreased centrality in regions involved in emotional regulation and ability to accurately attribute thoughts or intentions to others and with enhanced centrality in regions involved in internal emotional perception, self-referential thinking and self-awareness. This may provide a potential mechanism for how maltreatment increases risk for psychopathology.

Heather Koon Raped Babies At Ohio Daycare, Filmed At Least One Incident: Police (UPDATED)  10/07/2013

She was trusted to take care of defenseless children, but now one Ohio daycare worker is accused of doing the unthinkable — and filming it.

Heather Koon, 25, faces two counts of rape after police say they found video on her laptop of her “engaging in sexual conduct with an unknown infant.” An investigation also revealed an additional victim, according to WOIO.

Police allegedly found the video on Koon’s laptop at the apartment where her boyfriend, James Osborne, lives. Osborne is a registered sex offender. Both Koon and Osborne were arrested Oct. 4 within hours of each other, and were held at Lorain County Jail….

Elyria child daycare worker charged with rape
Jason Nguyen  Oct 7, 2013

LORAIN — Deputies say they have proof one woman raped two toddlers at a daycare center.

The Lorain County Sheriff’s Department has arrested 25-year-old Heather Koon for having sex with two infants at ABC KIDZ daycare in Elyria….

Deputies found a video of Koon raping the babies on a laptop after they checked up on her boyfriend, James Osborne.  Osborne is a sexual offender and was listed under another address.

Deputies arrested Osborne and then took the laptop.

Koon is charged with two counts of rape….

Hippocampal and Amygdalar Volumes in Dissociative Identity Disorder

Am J Psychiatry 163:630-636, April 2006
doi: 10.1176/appi.ajp.163.4.630….

METHOD: The authors used magnetic resonance imaging to measure the volumes of the hippocampus and amygdala in 15 female patients with dissociative identity disorder and 23 female subjects without dissociative identity disorder or any other psychiatric disorder. The volumetric measurements for the two groups were compared.

RESULTS: Hippocampal volume was 19.2% smaller and amygdalar volume was 31.6% smaller in the patients with dissociative identity disorder, compared to the healthy subjects. The ratio of hippocampal volume to amygdalar volume was significantly different between groups.

CONCLUSIONS: The findings are consistent with the presence of smaller hippocampal and amygdalar volumes in patients with dissociative identity disorder, compared with healthy subjects.

The neurobiological consequences of early stress and childhood maltreatment
Martin H. Teicher, Susan L. Andersena, Ann Polcarib, Carl M. Andersona, Carryl P. Navaltae, and Dennis M. Kima

Abstract
Early severe stress and maltreatment produces a cascade of neurobiological events that have the potential to cause enduring changes in brain development. These changes occur on multiple levels, from neurohumoral (especially the hypothalamic–pituitary–adrenal {HPA} axis) to structural and functional. The major structural consequences of early stress include reduced size of the mid-portions of the corpus callosum and attenuated development of the left neocortex, hippocampus, and amygdala.

Major functional consequences include increased electrical irritability in limbic structures and reduced functional activity of the cerebellar vermis. There are also gender differences in vulnerability and functional consequences. The neurobiological sequelae of early stress and maltreatment may play a significant role in the emergence of psychiatric disorders during development.
