Attention deficit hyperactivity disorder (ADHD)


Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by deficits in attention, concentration, activity level and impulse control.

Symptoms of the disorder are usually present in early childhood, but may only significant impair the child after he or she enters school. Although ADHD cannot be “outgrown”, children with ADHD can still adjust well to school and adult life if they receive interventions early

Doctors Listing



A diagnosis of ADHD should be made only after a thorough clinical assessment, which would include an interview with the parent or significant caregiver of the child. Additional information from other adults in the child’s life (e.g. school teachers, early childhood educators, close relatives) may aid in understanding the child’s condition.

If you think that your child might have ADHD, you are encouraged to seek help early from your trusted mental health professional. The symptoms are:


  • Fails to give close attention to details or makes careless mistakes
  • Has difficulty sustaining attention in task or play activities
  • Does not seem to listen when spoken to directly
  • Does not follow through on instructions or fails to finish school work, chores or duties
  • Has difficulties organizing tasks and activities
  • Avoids, dislikes, or is reluctant to engage in tasks that require sustained mental effort
  • Loses things necessary for tasks or activities
  • Easily distracted by external stimuli
  • Forgetful in daily activities

Hyperactivity / Impulsivity

  • Fidgets with hands or feet or squirms in seat
  • Leaves seat in classroom or in other situations in which remaining seated in expected
  • Runs about or climbs excessively in situations in which it is inappropriate
  • Has difficulty playing or engaging in leisure activities quietly
  • Often “on the go” or acts as if “driven by a motor”
  • Talks excessively
  • Blurts out answers before the question is completed
  • Has difficulty awaiting his/her turn
  • Interrupts / intrudes on others


Do note that the abovementioned symptoms need to affect the child’s functioning in most areas of his or her life, and not just in the classroom environment.




It is recommended for the child to receive a comprehensive treatment plan involving multiple treatment modalities so as to achieve the best outcome. Some examples of treatment include:


  • Pharmacological treatment
  • Psychosocial interventions (e.g., parent training programmes, classroom behaviour management)
  • Psychotherapy (e.g., behavior modification, family therapy)
  • Group work and therapy (e.g., social skills training)


It is strongly encouraged for the parents and school to work hand-in-hand in implementing the treatment plan so that the child can quickly learn to cope with his or her daily demands.
