Attention Deficit Hyperactivity Disorder (ADHD) is a condition that affects individuals of all ages. Historically, it was believed that ADHD only affected children, but research has shown that it can persist into adulthood. 

ADHD is a neurodevelopmental disorder that affects an individual's ability to focus, stay organised, and control impulsive behaviour. ADHD is a chronic condition that affects approximately 4-5% of adults worldwide. In recent years, there has been an increase in the number of adults being diagnosed with ADHD, with many people being diagnosed for the first time in their 40s.

Being diagnosed with ADHD at 40 can be both a relief and a challenge. On the one hand, individuals may finally have an explanation for why they have struggled with certain aspects of their lives, such as work, relationships, and organisation. On the other hand, it can be difficult to adjust to a new diagnosis, especially if an individual has lived their entire life without knowing they had ADHD. In addition, some individuals may feel stigmatised by their diagnosis, which can further complicate the adjustment process.

Another reason why more people are being diagnosed with ADHD is because of changes in the way the condition is diagnosed. In the past, ADHD was primarily diagnosed based on observable symptoms, such as hyperactivity and impulsivity. However, more recent diagnostic criteria have expanded to include inattentiveness, which is often more difficult to observe but can significantly impact an individual's life. This change in diagnostic criteria means that more individuals who previously may not have been diagnosed with ADHD are now being identified.

Despite the fact that ADHD has historically been thought of as a condition that primarily affects boys and men, recent research has shown that more women are being diagnosed with ADHD than previously thought. One reason may be that girls and women with ADHD often present differently than boys and men. For example, girls with ADHD are often less hyperactive and impulsive than boys, which means that their symptoms may be less noticeable to parents and teachers. Additionally, many women with ADHD have developed coping mechanisms to manage their symptoms, which can make it more difficult to identify the condition.

The key signs of ADHD include difficulty paying attention, hyperactivity, and impulsivity. These symptoms can manifest in a variety of ways, including difficulty focusing on tasks, forgetfulness, and disorganisation. Individuals with ADHD may also struggle with time management, procrastination, and impulsiveness, which can lead to problems in relationships and at work.

However, receiving a diagnosis later in life can also bring challenges. A person may feel a sense of grief or regret for not having received a diagnosis earlier, which can be difficult to come to terms with. They may also face stigma or judgment from others who do not understand the condition or its impact.

Furthermore, developing strategies to manage ADHD symptoms can be a significant challenge, especially for those who have developed coping mechanisms that may not be effective or healthy. It can take time and effort to learn new skills and make changes to one's lifestyle, but with support and resources, it is possible to thrive with ADHD.
