Can trauma change your IQ?

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 = .

Can PTSD cause loss of intelligence?

Results indicated that participants later diagnosed with PTSD had significantly lower intelligence, less formal years of education, and less motivation to serve compared to those who were not diagnosed with PTSD.

Can emotional trauma lower IQ?

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.

How does PTSD affect IQ?

Can PTSD change your brain chemistry?
