A new study published this month in the Journal of Neuroscience has profound implications for children of divorce. Researchers at the University of Wisconsin, Richard Davidson and Seth Pollak, examined the brains of a group of children using fMRI and compiled a detailed stressful life events history from their parents. Examining the brain scans revealed that both white matter (the connections between brain areas) and the gray matter (the cells that 'do the math') were LOWER in volume in children with greater levels of stress in their life history. This finding was particularly evident in the anterior cingulate portion of pre-frontal cortex, the part of the brain in the very front of the head that is responsible for "working memory". (Journal of Neuroscience , June 6, 2012)
As we know, divorce is a process and not an event. The period of time leading up to the divorce is a very stressful time for families, and the divorce process itself is particularly difficult for children. Children of divorce are frequently observed to be "absent minded" or "distracted" during and after the divorce, and this new research documents the physical changes that are taking place in the brains of these children that are evident in their behavior, particularly changes in their school performance. The decreases in the volume of both white and gray matter in the brain found in these children with more stressful life histories now provides a neuroscience foundation for the findings of the psychological research on children of divorce. Divorce is one of the most stressful life events for children but it certainly isn't the only one. Ongoing family violence, substance abuse, and neglect can all have deleterious effects on the brain development of young children, and profound effects on their emotional and intellectual, as well as social development.
The good news is that much of the new research on brain development is also finding that the brains of both children and adults is remarkably plastic, that is, capable of remarkable recovery and re-growth of new tissue when the conditions improve. The challenge for professionals involved in resolving family disputes and working "in the best interest of the children" is to find solutions that lead to rapid reductions in the stress levels of the family so that the children's brains can begin to grow again and regain the volumes of both gray and white matter that characterize healthy growing brains. For some families that means therapy and reconciliation for the parents that leads to a new pattern of better communication and lower stress levels.
For other families, when untreated mental illness or personality disorders in one or both parents make new behavior patterns in the family unlikely, a quick and low conflict divorce may be the avenue to lower stress that will allow the children to recover their lost brain function most quickly. At this point, we don't know how much stress for how long will lead to permanent and irreversible brain changes in children of divorce, but as this new line of brain scan-driven research develops, we will know more. Stay tuned.

Exposure to Family Violence and Brain Changes in Children--A Research Update
My last post highlighted the neural structures and processes involved in the development of parental alienation. This note summarizes some recent research about the connection between exposure to family violence and changes in brain functioning in children.
Researchers in the UK had noted that fMRI scans of combat veterans showed increased activation (when compared to veterans with NO combat exposure) in two areas of the brain: the amygdala and the anterior insula. These are two deep brain structures known to be active in the detection of threats, fear, survival responses, (amygdala) and of feelings of disgust or empathy, (anterior insula). These two deep brain structures have mirror neuron connections as well, leading to internal brain representation of external events, just like those noted in the post about parental alienation from last week.
This latest research compared the brains of two groups of children, neither of whom had any symptoms of mental health problems. One group of children came from families with documented histories of family violence; the other group of children had no such history. On a task that involved identifying faces as either male or female while in the fMRI scanner, the children with a history of "exposure to family violence" showed brain activation patterns similar to those of the veterans with combat experience--that is, activation of the two brain areas--the anterior insula and amygdala. The children with NO history of such exposure did NOT show similar activation on their fMRI scans.
This ground breaking research suggests that merely witnessing family violence leads to changes in children's brain function similar to those experienced by combat veterans. It is well known that post-traumatic stress disorder, PTSD, is characterized by "hyper-vigilance", and the chronic over activation of the neural processes involved in detecting threats and reacting to them. PTSD sufferers experience chronic fear and anxiety as a result of the over-activation of these same two brain structures (and some others).
What is not currently known is how much "exposure" is needed to result in these neural changes, nor why some children seem to avoid the long term consequences of anxiety and hypervigilance and distrust that other children experience from their exposure to family violence.
What is clear, even at this early stage, is that children are highly susceptible to measurable changes in brain function from exposure to family violence. The implications for family lawyers and courts would seem to include:
1. Children don't have to be physically injured by family violence to be adversely affected--just witnessing family violence is sufficient to cause adverse brain effects.
2. Intervention in escalating family violence at the early stages and removing potential for children being exposed to such scenes can prevent the emergence of those changes in brain function that increase the risks of development of anxiety and other maladies.
3. Leaving divorcing spouses together in the same house raises these risks for children since other divorce research has documented that nearly 100% of divorces involve at least one episode of physical violence between spouses. It is in the best interests of the children that their exposure to family violence be prevented.
