Researchers have found out that early life misfortune or stress can significantly decrease the size of brain regions which are typically associated with emotional processing and control. To contextualize the obtained brain data, scientists interviewed the children's parents. Both the brain data and the interview data suggested that when early-life misfortune becomes the norm of life, the nervous system would be overwhelmed and result in depression, obsessive compulsive disorder (OCD), anxiety, cancer, and even lack of career success in adulthood. Importantly, kids who experienced early-life misfortune often suffered from unconscious blackout of brain, and losing track of time. According to scientists, these physiological problems happen as a result of nervous system's reaction to protect ourselves. Furthermore, many children who suffered from early-life adversity reported that they tend to be uncommunicative to anyone with exception to their best friends and tend to interpret everyday experiences from a negative lens. But this does not mean that the life path of these children cannot be changed. Many participants of the study reported that the encouragement from family members and school teachers gradually develops their confidence; many of them reported doing well in school subjects, especially in math, and were able to gradually get rid of horrible thoughts with the help from friends and family members.
