Research suggests that around 3 to 4 percent of adults live with ADHD, although many remain undiagnosed until later in life. Because ADHD is often associated with childhood hyperactivity, adults who present differently may have their symptoms overlooked. This means a significant number of people only start to question whether they have ADHD once the demands of work, relationships, and daily life increase.

Time blindness is a common feature of ADHD. It describes the difficulty in perceiving and managing time, such as underestimating how long tasks will take, losing track of time altogether, or struggling to plan ahead. This can affect punctuality, work deadlines, and even relationships, often leaving the individual frustrated with themselves and others confused about their behaviour.

No. While medication can be highly effective for some, it is not the only approach to managing ADHD. Many adults benefit from a combination of strategies including therapy, coaching, lifestyle adjustments, and environmental adaptations, such as better organisational tools or structured routines. The right treatment plan is highly individual and depends on a person’s needs and preferences.

Yes. ADHD is a lifelong condition that begins in childhood, but it is not unusual for people to be diagnosed for the first time in their 30s, 40s, or even later. Some individuals manage to compensate for their difficulties when younger, often through structure, parental support, or academic environments. However, when adult responsibilities such as careers, bills, and family life build up, the challenges of ADHD often become more apparent.

Yes. Adults with ADHD frequently describe experiencing emotions more intensely than others. This may include quick frustration, sudden mood swings, difficulty calming down once upset, or a tendency to feel overwhelmed by everyday stress. Emotional regulation challenges are an important but often overlooked aspect of ADHD that can affect confidence and relationships.

This depends on your local NHS trust and policies. Some GPs accept private ADHD assessment reports and will provide shared care for medication prescribing, while others may not. It’s best to check directly with your GP before booking a private assessment so you know what to expect in terms of follow-up care.

Absolutely. Many people with ADHD excel academically, particularly if they are intelligent, have supportive environments, or can channel hyperfocus into their studies. Doing well at school does not mean ADHD wasn’t present. In fact, some adults look back and realise that although their grades were fine, the effort, stress, and hidden struggles behind them were signs of ADHD all along.

Yes, and the overlap is so common that it has its own term: AuDHD. Studies suggest that between 50 and 70 percent of autistic people also meet the criteria for ADHD. Both conditions share traits such as difficulties with attention, sensory processing, and executive function, although they remain distinct diagnoses. Recognising this overlap can help ensure a more accurate assessment and better-tailored support.

Not always. You can access certain tools, strategies, and even therapy without a formal diagnosis. However, having an official diagnosis can make it easier to access workplace or academic accommodations, receive ADHD-informed treatment, and gain a clearer understanding of yourself. For many adults, the process brings validation and direction as well as access to practical support.
