Childhood Trauma and Neurological Development Essay

Throughout the years, several adults have been affected by traumatic events that have taken place during their childhood(s). Lenore C. Terr (January, 1999) states, "Childhood trauma appears to be a critical etiological factor in the development of a number of serious disorders both in childhood and in adulthood." To better understand childhood trauma, Terr defines this as, the "mental result of one sudden, external or a series of blows, rendering the young person temporarily helpless and breaking past ordinary coping and defense operations" (January, 1999). The statistics of childhood trauma is alarming. In the United States, there are approximately five million children that experience trauma each year, with two million of these cases

Childhood maltreatment is a prevalent problem through out the world. As a child grows and matures the brain continues to develop according its experiences. During this time sensitive periods of development for different areas of the brain. A few areas that are of interest are the stress-influenced areas, which are at an increased risk for developmental problems when exposed to maltreatment. The extra stress from such exposures can influence abnormalities throughout the brain, which have been linked to structure changes with in the corpus callosum, anterior cingulate, dorsolateral prefrontal, orbitofrontal cortex, and hippocampus, amygdala, and cerebellum, as well as changes to stress related hormone systems. These structural changes are associated with an increased risk of psychopathology and other life long educational and physiological risk.

Traumatic brain injury (TBI) is a major health problem in industrialized societies. Associations between TBI and neuropsychiatric disorders have been recognized for many years. Impulsive aggression is one of the most socially and vocationally disruptive consequences of these neuropsychiatric disorders (Tateno, 2003).

Traumatic events also produce profound and lasting changes in physiological arousal, emotion, cognition, and memory. Moreover, traumatic events may result in the severance of these normally integrated functions from one another. Traumatized individuals may also suffer from the memories of the tragic or horrifying experiences they have undergone. Frequently, as a result of these many symptoms, it becomes inevitable for the individual to develop certain complications associated with trauma-related disorders, such as posttraumatic stress disorder.

The brain develops in such a way that it leaves itself vulnerable to these negative influences. The prenatal brain develops an overabundance of neurons, some of which are then carefully eliminated before age 4 (5). In a process similar to this, the amount of synapses between neurons is built up during early childhood and then pruned back for the next 30 years of life (5). These two processes are both disturbed by elevated levels of stress hormones (5). The two centers of the brain with the most postnatal changes, including the growth of new neurons after birth, are the hippocampus, which is part of the limbic system, and the cerebellar vermis (6). The hippocampus is in charge of creating and retrieving memories, working together with the other parts of the limbic system, such as the amygdala, which records the emotions for each memory. The vermis controls the production and release of two of the catecholamine neurotransmitters, dopamine and norepinephrine (6). Both the vermis and the limbic system have higher concentrations of receptors for the stress hormone cortisol than anywhere else in the brain (6). Due to this fact, these still-developing areas are the most vulnerable to the damage done by elevated levels of stress hormones.

The effects of trauma can be looked at into two separate categories however, they both are interrelated: neurodevelopment and psychosocial development. From the onset of birth, we are born with 100 billion neurons, much more than we will ever need and much more than we will ever have. Between these neurons, trillions of synapses are created. Depending upon the early life experiences in relation to attachments with caregivers and our environment, some synapses will be strengthened whilst others will be discarded.

Many children are exposed to traumatic events before they even become adults. All around the world they are exposed to child abuse, rape, natural disasters, terrorism, car accidents, and school violence among many others. Studies have shown that these traumatic events, if left untreated, can result in significant psychological problems, such as post traumatic stress disorder (PTSD) or other anxiety disorders, depression, or a number of other behavioral difficulties (Cohen, Mannarino, Berliner & Deblinger, 2000). These difficulties can become chronic and produce negative effects which could last into adulthood. It is therefore imperative that effective treatment strategies be

Individuals suffering from post-traumatic stress are accustomed to high levels of stress from the initial traumatic. This trauma continues to live in an individual through nightmares and flashbacks. Many individuals who have tolerated post-traumatic stress suffer from memory loss and other brain related changes. According to Moyer (2016), the hippocampal size in the brain has been shown to have an inverse relationship to the duration of PTSD symptoms; chronic stress conditions might continue to damage the hippocampus even after the initial trauma. Moyer (2016) also states that aside from increased stress caused by PTSD symptoms, a lack of control of cortisol levels might cause further damage to the brain, resulting in increased brain changes

Trauma is very complex and varied in its nature. Traumatic events include child abuse, neglect and maltreatment. Wamser‐Nanney & Vandenberg (2013) found that one of the more harmful types of trauma is the abuse is committed intentionally. This directly impacts the victim 's safety and sense of trust. The devastating effects of this type of trauma is the way in which it impacts not only the survivors, but also future generations, and the ability they have to form attachments (Connolly, 2011).

Childhood trauma is one of the most heartbreaking situations to ever fathom happening. Childhood trauma includes neglect, maltreatment, physical and emotional abuse, and many other forms of mistreatment amongst children. Childhood trauma occurs between the ages of 0 and 6 years of age. When referencing to childhood trauma, one must take thought into who commits the abuse, who is affected by the abuse, and what long term effects can the abuse have on the victims. One must also take into consideration the sex differences when referring to childhood trauma. Numerous of studies have been conducted and many findings have been made. Prior to conducting this research paper, I only considered childhood trauma to be what it was and never considered the long term effects. Because of my assumption, I never even considered the other categories of the trauma.

Traumatic brain injury (TBI), or intracranial injury, is a medical diagnosis which refers to closed or penetrative damage to the brain that is caused by an external source. Every year, TBIs affect approximately 150-250 people in a population of 100,000 (León-Carrión, Domínguez-Morales, Martín, & Murillo-Cabezas, 2005). The leading causes of TBI are traffic accidents, work injuries, sports injuries, and extreme violence (León-Carrión et al., 2005). TBI is most often fatal when the cause is an injury due to the use of firearms, a traffic accident, or a long fall (León-Carrión et al., 2005). However, fatality rates and rates of occurrence differ in various countries due to

Traumatic Brain Injury is otherwise known as TBI. “Traumatic brain injury, a form of acquired brain injury, occurs when sudden trauma causes damage to the brain. TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue” (NINDS, 2010). There are two main types of TBI, closed head injuries such as head hitting a windshield and penetrating head injuries such as a gunshot wound. As reported by the Global Neuroscience Initiative Foundation,” The severity of traumatic brain injuries is often assessed using the Glasgow Coma Scale, with scores ranging from 3 to 15. The higher the score,

The figures are very disheartening. According to Feldman (2014), at least five children are killed by their caretakers or parents daily. About 140,000 children experience physical abuse every year. Furthermore about 3 million children are either abused or neglected in the United States on a yearly basis (Feldman, 2014). Trauma is a term which is used to describe a drastic mental or physical experience in a person’s life which damages the normal emotional, and physical, attribute of the IWM. When children or youth experience trauma it impairs “his/her” emotional and physical well-being (National Center Brief). The common types of trauma which affect children greatly are community or domestic violence, neglect, medical attention, and physical or

Research shows that many brain and hormonal changes may occur as a result of early, prolonged trauma, and contribute to troubles with learning, memory, and regulating emotions. Combined with a disruptive, abusive home environment, these brain and hormonal changes may contribute to severe behavioral difficulties (“Post-Traumatic” 1).

Neurobiological research suggests that severe trauma is associated with reduced size of the brain cortex, which is responsible for memory, thinking, language, perceptual awareness, attention,
