Condition : ADHD
What is ADHD?
ADHD (attention deficit hyperactivity disorder) is not an illness or disease, and it is not linked to intelligence. It is a neurodevelopmental condition, which means your brain develops and works differently to others’. Symptoms usually start before the age of 12.
If you have ADHD, you may be inattentive (have trouble with concentration), hyperactive (have high energy levels), and impulsive (struggle to control your urges and think before acting).
You might have symptoms of both the inattentive and hyperactive-impulsive type or only show signs of one type.
Symptoms of the inattentive type include:
- being easily distracted or forgetful
- finding it hard to organise your time
- finding it hard to follow instructions or finish tasks
- losing things often, like your wallet, mobile, or keys
- forgetting everyday tasks, like brushing your teeth
Signs of the hyperactive-impulsive type include:
- having a lot of energy or feeling restless
- being very talkative or interrupting conversations
- making quick decisions without thinking about what might happen as a result
Women and girls with ADHD more commonly have inattentive symptoms which can be harder to recognise. This means ADHD isn’t identified in women and girls as often as it is in men and boys.
In children, particularly when they’re under the age of five, signs of being tired, anxious, or stressed may include getting easily distracted or being impulsive, which can be confused with ADHD.
People with ADHD may be more likely to have mental health issues, such as anxiety and depression, and are at higher risk of suicide.
What causes ADHD?
The cause of ADHD is not always known, but it may be caused by:
- genetic differences (meaning it runs in families)
- being born premature (before 37 weeks of pregnancy)
- having epilepsy
- a brain injury
- being autistic
