ADHD is a common chronic neurodevelopment disorder. It affects children and can continue in adulthood as well. This disorder encourages hyperactive and impulsive behaviour. Children also face problem in focusing on a certain task.


There are mainly 3 types of ADHD based on the severity of the symptoms. These are discussed below:

  • Predominantly Inattentive Presentation: The child finds it extremely difficult to pay attention to details, finishing tasks, organising and following instructions. However, the child does not create disturbance in the classroom and hence it is hard to diagnose early. Girls are more affected by it.
  • Predominantly Hyperactive-Impulsive Presentation: The impulsive behaviour of the child is reflected in his constant jumping, fidgeting and talking. It is difficult for the child to listen to others and hence he talks at inappropriate times and does not wait for his turn. This hyperactive behaviour makes the child more prone to accidents and injuries.

  • Combined Presentation: The child shows the impulsive and hyperactive behaviour along with being unable to focus. It can be said that child is equally inattentive and hyperactive-impulsive.


The cause of ADHD is unclear, but a genetic mutation has been linked to it. Along with it, there are a few other biological and environmental causes that may cause ADHD. They are:

  • Premature delivery
  • Low birth weight
  • Defective brain surgery
  • Pregnant women being exposed to toxic materials like lead
  • Excessive tobacco and alcohol use during pregnancy


Symptoms can be varied from mild to severe. Children can be diagnosed with ADHD as early as 3 years. Some of the symptoms include:

  • Easily distracted
  • Fidgeting
  • Talking a lot
  • Losing a lot of stuff
  • Daydreaming
  • Unusual energy levels
  • Trouble organising
  • Does not make friends easily
  • Taking unnecessary risks
  • Being careless


For the treatment of ADHD, it is recommended to take both medication and therapy into consideration.

  • Therapy: Therapy includes both behavioural and psychotherapy. Behavioural therapy helps the child to analyse his behavioural patterns and puts control on them intentionally. Psychotherapy can help the child to open up about his ADHD experience and accept it in a better way.
  • Medication: To treat ADHD, the child is given stimulants and non-stimulants. Antidepressants like bupropion and atomoxetine are used to treat ADHD. You are recommended not to take medication without a proper prescription from the doctor.
