What is attention deficit hyperactivity disorder?

Attention deficit hyperactivity disorder (ADHD) is a chronic condition which affects children resulting in difficulty maintaining concentration, impulsive behaviour with or without hyperactivity.  This condition may continue into adulthood.  Children affected by ADHD often performs poorly at school, have low self-esteem and have difficulty in building and maintaining relationships.

In the United States, 6.1 million children aged 2-17 years were diagnosed with ADHD and 5.4 million children already had ADHD in the year 2016.  From the year 1998-2009, the percentage of children diagnosed with ADHD has increased by 7-9%.  Males are 3-5 times more commonly affected by ADHD than females.

Unfortunately, there is no cure foe ADHD.  However, there are medications and behavioural therapies that can be used to relieve the symptoms associated with ADHD.  Seeking medical advice and getting the appropriate treatment early can make a big difference in the outcome.

What are the risk factors for ADHD?

The exact cause of ADHD is still not known.  However, there are some factors which may increase your risk of developing ADHD and these include:

• Family history: Having a parent or sibling affected by this condition increases your risk of developing ADHD.
• Maternal drug abuse during pregnancy
• Maternal alcohol abuse during pregnancy
• Being born prematurely
• Sex: Males are 3-5 times more at risk of developing ADHD than females.

What are the signs and symptoms of ADHD?

ADHD exists in mainly 3 basic forms including predominantly inattentive, predominantly hyperactive/impulsive and combined.

• Difficulty maintaining concentration or attention while performing tasks or play activities.
• Fails to give close attention to details.
• Makes careless mistakes in schoolwork or work.
• Often seems not to listen to what is being said.
• Strongly dislikes or avoids tasks that require sustained mental effort.
• Forgetfulness during daily activities.
