Childhood emotional trauma can cause brain changes

Changes in the temporal lobe may cause temporal lobe epilepsy which can include a variety of symptoms that are less obvious than a seizure. Feelings of disorientation from temporal lobe epilepsy can include “mind-body dissociation—the feeling that one is watching one’s own actions as a detached observer.”

These studies suggest that child abuse may alter development of the left hippocampus permanently and, in so doing, cause deficits in verbal memory and dissociative symptoms that persist into adulthood. ”

The left hemisphere is specialized for perceiving and expressing language…

The research suggests that children who experience trauma may have lasting damage occur in their left temporal lobe which is a part of the brain that contains the smaller hippocampus. Temporal lobe epilepsy is uncommon but is more of a risk for children who suffered trauma of some sort. It doesn’t cause seizures that are as obvious as those that occur in other types of epilepsy. Diagnosis can be difficult also because the patient would need to be having an EEG performed while having a temporal lobe seizure.

Symptoms may include: “Because these areas constitute a sizable, varied part of the brain, TLE has a veritable catalog of possible symptoms, including sensory changes such as headache, tingling, numbness, dizziness, or vertigo; motor symptoms such as staring or twitching; or autonomic symptoms such as flushing, shortness of breath, nausea, or the stomach sensation of being in an elevator. TLE can cause hallucinations or illusions in any sense modality. Common visual illusions are of patterns, geometric shapes, flashing lights, or “Alice-in-Wonderlandlike” distortions of the sizes or shapes of objects. Other common hallucinations are of a ringing or buzzing sound or repetitive voice, a metallic or foul taste, an unpleasant odor, or the sensation of something crawling on or under the skin. Feelings of déjà vu (the unfamiliar feels familiar) or jamais vu (the familiar feels unfamiliar) are common, as is the sense of being watched or of mind-body dissociation—the feeling that one is watching one’s own actions as a detached observer. Emotional manifestations of temporal lobe seizures usually occur suddenly, without apparent cause, and cease as abruptly as they began; they include sadness, embarrassment, anger, explosive laughter (usually without feeling happy), serenity, and, quite often, fear.4

*I find this information interesting because I have had some of these symptoms in the past and my migraine headache pain was always greatest in the same spot on the left side of my head.

Ways to help protect the infant’s brain /may/ include rocking the baby (probably-gently) from side to side (based on animal research) as it seems to be calming for the brain’s cerebellar vermis which is a section that may help control electrical activity and prevent seizures. Infant rats who were handled by humans for just five minutes or those whose mother (rat) spontaneously licked and groomed them all showed lasting changes in their development,  behavior, and response to stress later in life.

ADHD like symptoms are common for people who had a childhood history of trauma and a smaller size of the cerebellar vermis is common in ADHD: “Interestingly, one of the most reliable neuroanatomical findings in ADHD is reduced size of the cerebellar vermis.”

Successful treatments are not that common which makes prevention of child abuse and neglect important for protecting children’s longterm quality of life. EMDR treatment is discussed in the article. I did find the cognitive therapy technique helpful for my own trauma history. The difficulty with traditional ‘talk therapy’ for issues that developed during early childhood is that verbal reasoning might not have been present when the trauma occurred. EMDR is a type of relaxation technique that can help the patient access deeper emotionally charged memories that aren’t based in words.

Talking about trauma with kids; PTSD, neural mapping, EMDR and reframing

/This article was originally posted on March 21, 2011. It is still important to have open conversations with children about traumatic events or other information they may find confusing, troubling or frightening. EMDR therapy can be helpful for adults with PTSD./
We all need comfort and we gain it from sharing our burdens, talking about troubles and letting out worries. Listening is more important than talking – let kids talk to you about trauma – we don’t know what they are thinking or are worried about until we let them talk it out. Don’t worry too much about “how to talk about it”, pause, listen, and accept – “yes, there are worries but we’ll stick together and work through it”, is a strong message for all of us to hear.
Children and all of us have “hot” emotional memories centered in the amygdala and milder long term factual memories stored more generally throughout the neocortex. Electrical activity of the brain can be recorded and associated with the topic being considered. The amygdala centered emotional memory can be tied to smells, sounds, places or people and can be unexpectedly triggered leaving the person with panic attack type symptoms unique to the individual’s memories of the early traumatic event.

Douglas Buchanon described neural mapping in his blog “Follow the Neurons – Your Life Map” [TheGatesofHorn].Neural mapping is a bit like playing with a line of toy dominos. The designers spend hours placing the dominos in line, each the perfect distance and angle from the last, carefully balanced on end and poised for any slight shock to send the entire chain tumbling down. Emotional memories may be triggered by something like a car door slamming shut. A toddler memory may be submerged regarding something as trivial as mom and dad fighting over who has to carry in the groceries and the car doors were slammed shut violently. To a toddler the words may not mean as much as the tone and the violent sounds.

After the event, immediately, and maybe later that day, the next day, the next week – the toddler may pester with questions of what is wrong and what did I do to cause that fight? The child’s world is centered around themselves – natural while young but prone to self blame. The memory can be stored with feelings of “I caused that arguement – I am a bad person – I don’t deserve attention or explanation” and so on. If their worries are left unanswered or are denied as real then the hot memory is ignored and is left unprocessed, instead it is pushed down and forgotten at the daily level. A car door slamming with a combination of shouting voices might trigger a panic attack though.

The hot memory can be toned down and moved to long term storage if time is allowed to discuss the event – and more than once. It might pop up in the toddler’s chit chat daily, and then weekly, monthly, and maybe even over the years if it was bad enough triggering event. Once the connection is made though, (negative event associated with a negative symptom) and discussed, usually the power of the slamming/shouting sound is reduced and similar events in the future may not trigger a panic attack or it might  be a milder reaction.

Children are absorbing knowledge and building their neural pathways – good habits and bad habits are learned by watching the people they love and trust. Spending a few minutes whenever possible to listen to children share their worries allows them to move the memories from the ‘hot’ button zone of the amygdala, to the mellower long-term storage of the neocortex.

Symptoms of PTSD, Post Traumatic Stress Disorder, can be effectively reframed  and reduced using cognitive therapy techniques like EMDR. A problem or trigger event is visualized and then a state of deep relaxation is reached and the memory is discussed or pondered with guidance from the therapist. New insights from the perspective of the adult framing of the situation can be considered and then the relaxation method is repeated using the new perspective.  The neural maps of the traumatic events can be reached  from a deeply relaxed state of theta waves. EMDR, attempts to help the patient reach the theta state with rapid stimulation of the right side then left side of the brain, either visually with a moving hand or object, or with sound or a vibration buzz in the palm of the hand. Children under seven are already living in this more meditative level of consciousness. In the zone – flow time – playing like a child – we could all use a little relaxed theta time these days and a chance to free a little worry from the hot zone of the amygdala.

The world is changing but denying reality never solves problems it only pushes them down to a submerged hot zone. When we talk about our troubles then we can look for solutions and change. Denying problems, denies a chance for change.

Art therapy can be a useful way to give children and anyone freedom to explore feelings – color to feel not to produce. Playdough and other free form play can help reach a relaxed state where gentle talk about hot topics can be released  as they surface. Picking at the problem with needling questions may not be as quick as open ended play time. Adults may find a walk or bike ride their ticket to free flow brain time.
