Adult ADHD symptoms can affect every part of daily life, from work and relationships to emotional wellbeing. At The Therapy Company, we regularly support adults across Preston and Lancashire who are struggling with undiagnosed ADHD and looking for clarity through a professional assessment.
Adult ADHD in Preston and Lancashire
Many adults in Preston and the wider Lancashire area come to us after years of feeling overwhelmed, distracted, or misunderstood. ADHD is often missed in childhood and only becomes more noticeable in adult life when responsibilities increase.
Although the condition is often perceived as a childhood condition, it can persist into adulthood and have a significant impact on your personal and professional life. If you’re concerned about ADHD in a child or teenager, you can also read our guide to child ADHD assessments. According to ADHD UK, there are millions of people who have undiagnosed ADHD (up to 2 million in the UK).
In this latest blog, we explore the primary symptoms of adult ADHD including:
- Inattention symptoms
- Hyperactivity symptoms
- Impulsivity symptoms

What is Adult ADHD?
ADHD in adults and children can look similar but every person is complex with symptoms showing differently. Although some obvious symptoms can be identified and diagnosed in childhood, many are not identified until adulthood, when symptoms become more apparent in professional and personal contexts. Adult ADHD can affect various aspects of life, including work, relationships, and overall well-being. With the complexities of adult life, symptoms can be exacerbated.
Let’s get into the symptoms of adult ADHD…
Inattention ADHD symptoms
A key symptom of ADHD is struggling concentrating whether that be in your personal or professional life. You may notice that you zone out regularly or find it increasingly difficult to remain present during every-day conversations. Another key factor that falls under inattention symptoms is disorganisation. Here, it’s common for sufferers to have a hard time with managing schedules.
Further outstanding symptoms include:
- Poor Time Management: Frequently running late, missing deadlines, or underestimating the time needed for tasks.
- Forgetfulness: Regularly forgetting appointments, commitments, or daily tasks, such as paying bills or returning calls.
- Easily Distracted: Being quickly sidetracked by unrelated thoughts or external stimuli, leading to unfinished tasks.
- Avoidance of Complex Tasks: Avoiding tasks that require sustained mental effort, such as detailed reports or lengthy emails.
- Careless Mistakes: Frequently making mistakes due to a lack of attention to detail, especially in work or academic settings.
Hyperactivity and Impulsivity symptoms
For some people, hyperactivity and impulsivity symptoms naturally decrease into adulthood. However, for many, hyperactivity remains prevalent often leading to increasingly likely impulsive behaviour and restlessness. Adults with ADHD (diagnosed or undiagnosed) may commonly experience feeling on edge or finding it difficult to relax.
Further outstanding symptoms include:
- Excessive Talking: Talking excessively, often interrupting others or dominating conversations.
- Impulsivity: Making hasty decisions without considering the consequences, leading to problems in personal and professional life.
- Difficulty Waiting: Struggling to wait in lines or for their turn in conversations.
- Interrupting Others: Frequently interrupting or intruding on others’ activities or conversations.
- Feeling Driven By A Motor: A sense of being constantly “on the go” or acting as if driven by a motor.
Diagnosis of Adult ADHD
Here at The Therapy Company, our private psychiatrists provide private ADHD diagnosis at our facility in Preston, as well as also providing online consultations and appointments. The diagnosis of adult ADHD is carefully considered and can be challenging due to many symptoms overlapping with mental health conditions such as anxiety, depression, and other mood disorders.
A comprehensive evaluation by our private psychiatrists is necessary for an accurate diagnosis.
Our assessments include the following process:
- Initial consultation
- Discussing symptoms
- Clinical interviews
- Collateral reports
- Reviewing childhood history
- Ruling out other conditions
- Applying diagnostic criteria
- Final diagnosis
You can learn more about our full diagnostic process on our adult ADHD assessment page.
There are several steps involved in the diagnosis process and this is imperative for ensuring an accurate diagnosis before discussing possible treatments which may include medication, Cognitive-Behavioural Therapy (CBT), and lifestyle changes.
Impact of Adult ADHD
Adult ADHD can significantly affect various aspects of life:
- Workplace Performance: As a result of impulsivity and hyperactivity symptoms, workplace performance is commonly impacted and deadlines can be missed, as well job instability becoming a real issue for many.
- Relationships: Personal and professional relationships can take a toll as a result of ADHD symptoms. It’s common for sufferers to become more forgetful and more impulsive. As a result of this, it can have a negative strain on relationships.
- Financial Management: Unpaid bills and impulsive spending can have a major impact which ultimately may result in financial problems. This is another impact of adult ADHD.
- Self-Esteem: With ADHD, you are challenged persistently which can lead to low or fluctuating self esteem. As a result of this, it can cause further mental health conditions such as depression or anxiety.
- Daily Life Management: Daily life can also be impacted and it may become overwhelming to maintain a household, manage schedules, and keep on top of personal care.

Frequently Asked Questions about Adult ADHD
Can ADHD go undiagnosed in adults?
Yes, ADHD can often go undiagnosed in adults, especially if symptoms were missed in childhood. Many adults in Preston and across Lancashire only seek an assessment later in life when difficulties with concentration, organisation, work performance, or relationships become more noticeable. Adult ADHD is frequently mistaken for anxiety, depression, or stress, which is why a specialist assessment is important for an accurate diagnosis.
How do I get an ADHD assessment in Preston?
To get an ADHD assessment in Preston, you can book a private consultation directly with a qualified psychiatrist or clinic that specialises in ADHD. At The Therapy Company, we offer private adult ADHD assessments at our Preston clinic, as well as online appointments. The process typically includes an initial consultation, a detailed clinical interview, and a full diagnostic review based on recognised clinical criteria.
Is adult ADHD treated differently from childhood ADHD?
Adult ADHD is often treated differently from childhood ADHD because symptoms can present in more subtle ways. While children may show more obvious hyperactivity, adults are more likely to experience difficulties with attention, organisation, emotional regulation, and impulsive decision-making. Treatment for adults usually focuses on a combination of medication, therapy such as CBT, and practical strategies to manage daily life and work responsibilities.
Do I need a GP referral for a private ADHD assessment?
Yes, a GP referral is required for a private ADHD assessment at The Therapy Company. This ensures that all relevant medical information is considered and that assessments are carried out safely and appropriately by our consultant psychiatrists. If you are based in Preston or Lancashire, your GP can provide a referral directly to our clinic, or you can contact us for guidance on how to arrange this.
