The usual treatment combines medication, most often psychostimulants that increase the availability of dopamine and noradrenaline, with behavioural therapy; non-stimulant options such as atomoxetine or guanfacine exist too. With young children the starting point is usually behavioural intervention and work with the parents, on routine and motivation; with adults, therapeutic support is added along with changes in how they organise the day. These are interventions with solid evidence behind them, and they remain the foundation.
