What Are the Main Symptoms of ADHD?

ADHD is characterised by a range of symptoms that affect attention, impulsivity, and hyperactivity. These symptoms are typically grouped into three main categories: inattentive, hyperactive-impulsive, and combined types. Understanding these differences is essential for identifying how ADHD presents itself in individuals.

Inattentive ADHD: This type is characterised by difficulty in maintaining focus on tasks, becoming easily distracted, and struggling with organisation. People with inattentive ADHD may frequently lose items, forget appointments, or seem “daydreamy.” They are often described as not paying attention but, in reality, they find it difficult to maintain focus, especially when tasks are long or uninteresting. Key traits include:
- Trouble sustaining attention.
- Frequently making careless mistakes in work or school activities.
- Difficulty organising tasks and activities.
- Avoiding or being reluctant to engage in tasks that require sustained mental effort.
Hyperactive-Impulsive ADHD: This type involves behaviours that include excessive movement, fidgeting, and impulsivity. Those with hyperactive-impulsive ADHD may act without thinking, interrupt conversations, or find it hard to stay still. Children with this type are often described as being constantly on the go. Typical behaviours include:
- Fidgeting or squirming in their seat.
- Difficulty remaining seated in situations where it is expected.
- Talking excessively or blurting out answers before questions have been completed.
Combined ADHD: The most common type of ADHD is a combination of both inattentive and hyperactive-impulsive symptoms. People with combined ADHD exhibit traits from both categories, which can make daily activities more challenging. They may struggle to concentrate in school or work, while also displaying hyperactive behaviours that make it hard to sit still or wait their turn.

These symptoms are not just fleeting behaviours; they persist over time and can severely impact everyday life. This is why early diagnosis and intervention are key to managing the condition effectively.

How is ADHD Diagnosed?

In the UK, the diagnosis of ADHD follows a structured process that involves healthcare professionals assessing a range of behaviours over time. Since ADHD can present differently in individuals, a comprehensive evaluation is crucial to ensure an accurate diagnosis.

For children, diagnosis often begins when teachers or parents notice persistent difficulties in school or at home. The child may have trouble concentrating, staying organised, or may exhibit disruptive behaviour. A GP will usually be the first point of contact. If the GP suspects ADHD, they will refer the child to a specialist, such as a paediatrician or child psychologist, who will carry out further assessments. These assessments involve:

Gathering detailed information about the child’s behaviour in various settings, such as at home and in school.
Interviews with parents, teachers, and the child to understand how symptoms affect daily life.
Rating scales and questionnaires to assess the severity of the child’s symptoms.

For adults, the path to diagnosis is often more complex. Many adults with ADHD go undiagnosed for years, only seeking help when they encounter significant difficulties in managing work or personal life. Adults may struggle with disorganisation, procrastination, and time management, leading them to seek professional help. The diagnosis process for adults typically includes:

A detailed personal and family history of symptoms.
A psychological evaluation to rule out other mental health conditions.
Standardised questionnaires or scales to measure symptoms.

It's important to note that ADHD symptoms must be present in multiple settings (e.g., home, school, work) and have a noticeable impact on the individual's daily life to meet the criteria for a diagnosis. Additionally, other conditions such as anxiety or depression can co-exist with ADHD, making it essential for the diagnosis to consider all aspects of the individual’s health.

What Causes ADHD?

The exact cause of ADHD is not fully understood, but research suggests a combination of genetic and environmental factors contribute to the development of the condition.

Genetic Factors: ADHD tends to run in families, indicating a strong genetic component. Children whose parents or siblings have ADHD are more likely to develop the condition themselves. Twin studies have shown that identical twins are more likely to both have ADHD compared to non-identical twins, further supporting the idea that genetics play a key role. However, no single gene has been pinpointed as the cause.
Brain Structure and Functioning: Research has shown that people with ADHD may have differences in brain structure and function. Areas of the brain involved in attention, impulse control, and executive functioning (such as planning and decision-making) appear to be smaller or less active in individuals with ADHD. Neurotransmitters, particularly dopamine, also play a role in ADHD, as dopamine is involved in reward and motivation. Some research suggests that people with ADHD may have an imbalance in dopamine levels, which can affect their ability to regulate attention and behaviour.
Environmental Factors: Although genetics play a significant role, environmental factors can also contribute to the development of ADHD. These factors include exposure to toxins such as lead, smoking or alcohol use during pregnancy, and premature birth. However, it's important to note that these factors alone do not cause ADHD; they may increase the likelihood of developing the condition in individuals who are already genetically predisposed.

While much is known about the underlying causes of ADHD, there is still ongoing research into how different factors contribute to its development. Understanding these causes is crucial for improving diagnosis and treatment options.

What Are the Treatment Options for ADHD?

ADHD can be managed effectively with a combination of treatments, tailored to the needs of the individual. In the UK, treatment typically involves a combination of medication, behavioural therapies, and lifestyle adjustments.

Medication: The most common treatment for ADHD is medication, particularly stimulant medications such as methylphenidate (Ritalin) and dexamfetamine (Dexedrine). These drugs work by increasing the levels of neurotransmitters in the brain, which helps improve focus and reduce hyperactive and impulsive behaviour. Non-stimulant medications such as atomoxetine (Strattera) are also available for individuals who do not respond well to stimulants.
Behavioural Therapy: For both children and adults, behavioural therapy is a key component of treatment. Cognitive Behavioural Therapy (CBT) helps individuals develop strategies to manage symptoms, such as improving organisation, time management, and coping with impulsivity. In children, parent training and school interventions are also essential to ensure that the child receives support in both home and school environments.
Lifestyle Changes: A healthy lifestyle, including regular exercise, a balanced diet, and sufficient sleep, can significantly help manage ADHD symptoms. Exercise is particularly beneficial as it helps reduce hyperactivity and improves concentration. Additionally, creating structured routines and using organisational tools can help individuals stay on track with daily tasks.

The effectiveness of treatment varies from person to person, and it's often necessary to try different approaches to find the most effective combination. Regular monitoring and adjustments to treatment plans are essential to ensure ongoing success.

Can ADHD Affect Sleep?

Sleep difficulties are common among people with ADHD. Many children and adults with the condition struggle with falling asleep, staying asleep, or waking up feeling refreshed. These sleep problems can exacerbate ADHD symptoms, leading to a cycle of fatigue and difficulty concentrating.

Several factors contribute to sleep difficulties in people with ADHD:

Hyperactivity: Children and adults with ADHD may have trouble winding down at night due to excessive energy or restlessness.
Mind Racing: Many individuals with ADHD experience racing thoughts when they try to sleep, making it difficult to relax and drift off.
Coexisting Conditions: Anxiety and depression, which often co-exist with ADHD, can also interfere with sleep patterns.

Improving sleep hygiene is an essential part of managing ADHD. Simple changes, such as establishing a consistent bedtime routine, reducing screen time before bed, and creating a calm sleep environment, can help. In some cases, medication may be prescribed to help regulate sleep, particularly if ADHD-related hyperactivity or anxiety is preventing restful sleep.

So, How Can a Simple Card Help with All This?

While therapy and medication manage the condition internally, an ADHD card is a practical tool for managing your interactions with the outside world. The daily stress of having to explain yourself—at airport security, in a busy shop, or when you're feeling overwhelmed and can't find your words—is exhausting.

A card acts as a discreet and clear advocate in your pocket. It can calmly explain to someone that you have ADHD and might need a moment of patience or a clearer instruction, all without you having to say a word. It's a tool designed to reduce stress, not create it, giving you more space to manage the moment.

If you feel a card like this could make your life a little easier, we've put together a full guide to all the different styles we offer, from personalised photo IDs to simple, private awareness cards.
