| Attention deficit hyperactivity disorder, also known as hyperactivity disorder, is a common type of mental disorder in childhood. It is manifested as inattention, short attention span, hyperactivity, and impulsiveness that are not commensurate with age and developmental level, often accompanied by learning difficulties, conduct disorders and maladjustment. The disease started before school and was a chronic process. The disease not only affects children’s school, family and off-school life, but also easily leads to persistent learning difficulties, behavioral problems and low self-esteem. Such children have difficulty getting along with others at home and school. If they cannot be treated in time, some children still have symptoms in adulthood, which obviously affects their academic, physical and mental health, and family life and social skills in adulthood. |
