There were significant differences in the impact of childhood trauma on IQ across the 3 groups. Exposure in HCS was associated with a nearly 5-point reduction in IQ (−4.85; 95% confidence interval [CI]: −7.98 to −1.73, P = . 002), a lesser reduction in siblings (−2.58; 95% CI: −4.69 to −0.46, P = .
Using the derived regression equation to estimate effect sizes, a child experiencing both violence exposure and trauma-related distress at or above the 90th percentile would be expected to have a 7.5-point (SD, 0.5) decrement in IQ and a 9.8-point (SD, 0.66) decrement in reading achievement.
Trauma-induced changes to the brain can result in varying degrees of cognitive impairment and emotional dysregulation that can lead to a host of problems, including difficulty with attention and focus, learning disabilities, low self-esteem, impaired social skills, and sleep disturbances (Nemeroff, 2016).
For example, Vasterling, Brailey, Constans, Borges, and Sutker (1997) reported that Gulf War veterans with PTSD had significantly lower Wechsler Adult Intelligence Scale–Revised (WAIS–R; Wechsler, 1981) Verbal and Full Scale IQs relative to comparable veterans without PTSD.
That is, childhood maltreatment has an effect on emotional intelligence through its influence on social support, which affects the development and degree of mental symptoms. The study provided a theoretical basis for inhibiting mental symptoms through addressing their social support and emotional intelligence.
Learning problems, including lower grades and more suspensions and expulsions. Increased use of health and mental health services. Increase involvement with the child welfare and juvenile justice systems. Long-term health problems (e.g., diabetes and heart disease)
Childhood trauma in adults also results in feeling disconnected, and being unable to relate to others. Studies have shown that adults that experience childhood trauma were more likely to struggle with controlling emotions, and had heightened anxiety, depression, and anger.
PTSD patients whose symptoms increased over time showed accelerated atrophy throughout the brain, particularly brainstem and frontal and temporal lobes. Lastly, for the sample as a whole greater rates of brain atrophy were associated with greater rates of decline in verbal memory and delayed facial recognition.
Traumatic stress can change the brain's delicate chemical balance and structure. These effects, which can impact the way we function, can be minor or severe depending on the type of traumatic stress we're dealing with.
Interestingly, although significant correlations between stress and EI and between EI and IQ were found, no significant correlation between stress and IQ was observed. We can infer that this result may be related to brain structure.
The most common causes of childhood trauma include: Accidents. Bullying/cyberbullying. Chaos or dysfunction in the house (such as domestic violence, parent with a mental illness, substance abuse or incarcerated)
Children don't magically “get over” trauma when they turn 18. Trauma, toxic stress, and adverse childhood experiences permanently change a child's body and brain, which can have serious, lifelong consequences, according to a recent report from the Center on the Developing Child at Harvard University.
Adults with histories of trauma in childhood have been shown to have more chronic physical conditions and problems. They may engage in risky behaviors that compound these conditions (e.g., smoking, substance use, and diet and exercise habits that lead to obesity).
There were significant differences in the impact of childhood trauma on IQ across the 3 groups. Exposure in HCS was associated with a nearly 5-point reduction in IQ (−4.85; 95% confidence interval [CI]: −7.98 to −1.73, P = . 002), a lesser reduction in siblings (−2.58; 95% CI: −4.69 to −0.46, P = .
Traumas like physical and emotional trauma often lead to PTSD which on average, affects roughly 8% of Americans. PTSD can typically be a lifelong problem for most people, resulting in severe brain damage.
Brain areas implicated in the stress response include the amygdala, hippocampus, and prefrontal cortex. Traumatic stress can be associated with lasting changes in these brain areas.
Ever since people's responses to overwhelming experiences have been systematically explored, researchers have noted that a trauma is stored in somatic memory and expressed as changes in the biological stress response.
For individuals who continually experience traumatic events, or who relive traumatic memories from their childhood as adults, this means the brain can rewire itself in such a way that sometimes causes us to feel overly stressed, even when there's nothing overt to stress about.
Previous studies have shown that another brain structure, the hippocampus, is smaller in people with PTSD than in those without the disorder.
Symptoms of facial aging and trauma can range from wrinkled, drooping skin to injuries that cause pain and interfere with sight, smell, speech and breathing. Symptoms of aging skin can include: Fine lines and wrinkles. Loss of skin elasticity.
van der Kolk writes that there are three avenues for recovery: “top down, by talking, (re-) connecting with others, and allowing ourselves to know and understand what is going on with us”; “taking medicines that shut down inappropriate alarm reactions"; and “bottom up, by allowing the body to have experiences that ...
Move your body in a way that feels good. Trauma disrupts your body's natural equilibrium, keeping you in a state of hyperarousal and fear. Exercise can be a great way to release energy. Endorphins shake up your physical experience if you have been feeling stuck.
Some of the symptoms of trauma in children (and adults) closely mimic depression, including too much or too little sleep, loss of appetite or overeating, unexplained irritability and anger, and problems focusing on projects, school work, and conversation.
Without treatment, repeated childhood exposure to traumatic events can affect the brain and nervous system and increase health-risk behaviors (e.g., smoking, eating disorders, substance use, and high-risk activities).
