ADHD doesn’t only affect children
Attention-deficit/hyperactivity disorder (ADHD) is often associated with childhood, but many people carry the condition into adulthood, sometimes without realising it. Adult ADHD can impact work performance, relationships, finances, and emotional well-being. It often presents differently than in children, making it harder to diagnose. Awareness of adult ADHD is growing, and understanding the signs can be the first step to getting the proper support and improving your quality of life.
Common signs and symptoms of adult ADHD
While not everyone experiences the same symptoms, the most common signs fall into three main categories: inattention, hyperactivity, and impulsivity.
Inattention
- Difficulty focusing on tasks, especially long or repetitive ones.
- Frequently making careless mistakes or overlooking details.
- Trouble organising tasks, managing time, or meeting deadlines.
- Frequently losing items like keys, phone, or paperwork.
- Avoiding or delaying tasks that require sustained mental effort.
- Being easily distracted by unrelated thoughts or external stimuli.
Hyperactivity (often more subtle in adults)
- Feeling restless or “on edge” much of the time.
- Trouble sitting still for long periods (e.g. during meetings).
- A constant need to stay busy or multitask.
- Talking excessively or interrupting conversations.
Impulsivity
- Interrupting others or finishing their sentences.
- Struggling to wait your turn in conversations or queues.
- Making impulsive decisions (e.g. spending, changing jobs).
- Difficulty managing emotional reactions or frustrations.
Emotional and behavioural signs
Adult ADHD isn’t just about attention; it can affect emotional regulation too.
- Mood swings or emotional outbursts.
- Low frustration tolerance or frequent irritability.
- Feelings of anxiety, especially related to underperformance.
- Chronic boredom, even during stimulating activities.
- Trouble coping with stress or change.
These emotional symptoms can be mistaken for anxiety or depression, which often co-exist with ADHD.
Challenges in daily life
People with undiagnosed ADHD often struggle with:
- Career instability or frequent job changes.
- Difficulty managing household responsibilities.
- Relationship conflict due to inattentiveness or impulsivity.
- Financial trouble linked to poor planning or impulsive spending.
- Low self-esteem from years of perceived underachievement.
Recognising these patterns can be a breakthrough moment.
What causes ADHD in adults?
ADHD is a neurodevelopmental condition. While symptoms often begin in childhood, some individuals may only be diagnosed in adulthood, especially if their symptoms were mild or masked earlier in life.
Genetics play a strong role, and environmental factors such as prenatal exposure to toxins or early childhood trauma may also contribute.
Diagnosis and treatment
If you recognise these signs in yourself, it’s essential to consult a healthcare professional for a proper assessment. Adult ADHD is diagnosed based on medical history, behavioural assessments, and sometimes input from family or partners.
Treatment may include:
- Medication (e.g. stimulants or non-stimulants).
- Cognitive-behavioural therapy (CBT) for improving focus and emotional regulation.
- Coaching or counselling to develop organisational and coping skills.
- Lifestyle changes, including exercise, sleep hygiene, and mindfulness.
If you’re experiencing symptoms of adult ADHD, don’t wait to get help. Connect with a Intercare provider and book your appointment online.
