Yes, but it needs a process. Don't expect results soon. The human brain has only developed so fast. It is certainly useful to improve children's concentration through some training methods, such as painting and specific games. When the child's brain is unbalanced, it will naturally appear a state of inattention, so it is very helpful to train the child to develop the whole brain to improve his concentration. In addition, the development of children's whole brain, especially the improvement of concentration, should be sooner rather than later.
