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.
I wrote about the EMDR therapy technique in this post: Talking about trauma with kids; PTSD, neural mapping, EMDR and reframing,
