Since brain circuits are vulnerable in early childhood, early stressors may impact the development of necessary brain connections. [4] Therefore, the theory of toxic stress is that stress might alter or impair brain circuit formation and essentially result in a small brain size in young children. [4]
Scientific evidence shows that the toxic stresses of poverty can affect the brains of babies in the womb — but also that they can be reversed with some radical shifts to our approach to prenatal ...
Regular stress in young children could become toxic and cause brain damage, which can persist into adulthood.
These stress hormones are also hindering the hippocampus from receiving enough energy by diverting glucose levels to surrounding muscles. [2] Stress affects many memory functions and cognitive functioning of the brain. [10] There are different levels of stress and the high levels can be intrinsic or extrinsic.
A primary target of stress is the brain. When exposed to stress, it serves as the centre to interpret the stressors and determine the appropriate behavioural and psychological responses. [7] Therefore, exposure to chronic stress will have a direct impact on brain function. [7] For instance, chronic stress inhibits neuron growth inside the ...

Maternal stress levels may affect the developing child's intelligence. The timing and duration of stress can greatly alter the fetus' brain development which can have long-term effects on intelligence. Maternal reactions to stress such as increased heart rate are dampened during pregnancy in order to protect the fetus.
Exposure to ACEs, which exert effect by increasing an individual exposure to toxic stress during key periods of development, has also been linked to higher risks of chronic diseases, respiratory and heart disease, cancer and suicide. [4] More specifically, improper prenatal care increases the risk of premature births and complications during ...
