Exact causes of Behavioural Disorders are not known. Few of the causes established by researchers which may cause behavioural disorders are as follows:
- Genetics: Some neurobiological changes in body affect functioning of brain.
- Chronic illness: Child suffering with prolonged physical illness or any disability
- Damage to brain: Injury to brain during difficult labour or other accidental injury later in life
- Way of Upbringing: Lack of proper parental supervision, discipline, child abuse or child neglect
- Emotional factor: Child who has witnessed parental separation or divorce or constant fights between parents. Those kids whose parents are addicted to any substance (substance abuse) can also develop BEHAVIOURAL DISORDERS.
- Others: Malnutrition, protein deficiency, lead poisoning, use of alcohol or nicotine by mother during pregnancy.
- Smoking: Many studies indicate that if children are exposed to passive smoking early in life, then it could lead to Behavioural Disorders.
