Once again it’s October and time to celebrate ADHD Awareness Month, and this year’s theme is ‘Knowing is better!’ Knowing is something that would benefit all people who have attention deficit hyperactivity disorder (ADHD) – not only knowing about it themselves, but also others having awareness of and recognising the condition, be they the public, employers, politicians, teachers or doctors. ADHD is found in people across all walks of life, and awareness of ADHD is important because it is one of the most treatable disorders, whether by pharmacological or non-pharmacological methods; awareness can lead to treatment, which minimises risk for those with ADHD and those around them. Awareness is also important to help people recognise the positive traits of a person with ADHD, which can be rewarding for family, friends, work colleagues and society in general. Societies that pride themselves on embracing diversity should include those labelled with a mental health condition by ensuring that they have appropriate employment opportunities – women had a similar struggle to gain acceptance in varied roles in the workplace during the last century.
