Accordingto the cognitive development theory, Piaget emphasizes on theimpression of a traumatic event on a teenager[ CITATION Tha12 l 1033 ].For instance, a loss of a parent, sexual or physical abuse can leavea long-term impact on a child’s brain. Teenagers suffering fromdepression tend to change their personality as they try to cope withthe condition[ CITATION Tha12 l 1033 ].For example, children are highly likely to opt for negative copingmechanisms such as binge drinking or substance/ drug abuse. Teenagerssuffering from depression and moodiness require maximum support fromteachers to prevent adverse impacts such as suicide.
