ADHD (Attention Deficit Hyperactivity Disorder)

ADHD (attention deficit and hyperactivity disorder) is a condition that affects the way your brain works. It’s one of the most common neurological conditions, tending to cause problems focusing, regulating your behaviour (such as being impulsive or overactive), or both.

• Predominantly inattentive. You mostly struggle with organisation and paying attention. People with this type of ADHD might often find themselves losing their belongings and their focus. You might have heard this type of ADHD be referred to as ADD, though this is an older term that isn’t really used any more. ^[1]
• Predominantly hyperactive-impulsive. This subtype is more commonly seen in children than adults.^[2] It can make you struggle to sit still, behave impulsively, talk a lot (or out of turn) or become easily irritable.
• Combined presentation. This is where you show significant symptoms of both of the above types.

Anyone can get ADHD, but it’s more commonly diagnosed in children than in adults. For some, this is because they learn to understand and manage their symptoms better as they get older.^[1] It’s likely, though, that you never really ‘grow out of’ ADHD. Just that you get better at managing it, and that studies seem to suggest that adult ADHD is more common than is ‘officially’ diagnosed.^[2] This is because we’ve been learning more about it in recent years, so older adults who grew up with ADHD will have likely gone undiagnosed.

Studies also show that males are diagnosed with ADHD more than females are – with one study estimating a 2.2% global prevalence for men, compared to just 0.7% for women.^[3] But again, it’s contested whether the condition actually is more commonly found in boys than girls, or whether they might just be more likely to be diagnosed. It’s thought that girls might mask their symptoms better than boys do, or show them differently. It’s also thought that parents, clinicians and teachers might not be able to identify these symptoms in girls as well as they can in boys. ^[4]

No one quite knows the exact cause of ADHD, but there’s evidence to suggest that you’re more likely to be diagnosed if you have a family history of it. ^[1] Some other things that might increase the likelihood of it are:

• being born before the 37th week of pregnancy;
• smoking, drinking or drug abuse during pregnancy; or:
• being underweight at birth.^[2]

ADHD is a developmental condition, meaning that you’ll have it from an early age (even if you’re not aware at the time). It can’t be caused by any lifestyle factors or other conditions.

ADHD symptoms can be split into two categories, depending on whether they indicate inattentiveness or hyperactivity.

• Struggling with timekeeping or organisation
• Frequently forgetting things
• Losing concentration when being spoken to or daydreaming
• Struggling to follow or recall instructions
• Having a short attention span
• Constantly changing tasks

• Constant fidgeting, especially in calm or quiet environments
• Interrupting conversations
• A reduced sense of danger
• Acting without thinking
• Struggling to wait for a turn in group activities

• Organisation and time management
• Decision making and restlessness
• Taking unnecessary risks in activities, such as dangerous driving
• Forgetfulness, or frequently losing belongings
• Dealing with stress
• Mood swings and irritability
• Keeping quiet or speaking out of turn
• Focusing on and prioritising tasks ^[2]

There is no single test to diagnose ADHD, however a specialist is usually able to form a diagnosis after a conversation about your symptoms and seeing some supporting evidence.

In order to be diagnosed with ADHD, your symptoms will likely have to have been present from an early age (they may need to speak to people who have known you well since childhood if you can’t clearly remember). This is because it can’t develop later in life, so if you had no childhood symptoms this might mean that you’re experiencing the symptoms of another condition.

For a child to be diagnosed with ADHD, they either have to demonstrate six symptoms of inattentiveness or six symptoms of hyperactivity. In adults, diagnosis can be a bit more tricky. This is because symptoms can be harder to spot, and there’s some disagreement over whether the same symptoms that are used to diagnose children and teenagers should be used to diagnose adults, too.

To be diagnosed as an adult, you’ll probably have to demonstrate that your condition has a noticeable impact on your life, such as hindering your performance at work or putting strain on your personal relationships. Some specialists might specify that you either have to show five symptoms of inattentiveness or five symptoms of hyperactivity. ^[1]

For young children with ADHD, the first line of treatment is usually emotional support and behavioural training, and medication can then be used as well if these methods aren’t working well enough to manage the symptoms effectively.
