I've lived with ADHD all my life. It's just taken me most of my life to realise it.
I assumed I was normal. I thought that taking on too much, getting distracted, and being impetuous, hyperactive and inattentive were symptoms of my frantic life, not the cause.
A glimpse at my school reports is enough to confirm that I was always this way.
"I'm a bit of a chameleon," I told a therapist once. "Then you shouldn't sit on a patchwork quilt," he replied. Genius. I realised later that he was the well-known psychiatrist Arthur Hyatt Williams.
Similar, although less original, analogies have been applied: tuning into lots of channels simultaneously, mind like a pinball machine, flibbertigibbet and so on. All of them fit.
For a child in class, such mental overload and so many distractions make it almost impossible to settle and learn, and each failure or reprimand damages the self-esteem.
Yet, by the same token, a constantly shifting mind is incredibly creative: making connections, jumping boundaries, chasing thoughts. Attention deficit? Attention surfeit, more like. As a comedian, ADHD is my best friend and my worst enemy. It launches flights of imagination but hinders the organisation of them (or me). Oysters produce pearls when a foreign object invades their shell. Do I really want to be cured?
Jonathan Drane: My diagnosis was the result of exhaustive efforts by my mother, who was desperately trying to keep her son in a school that seemed content with the perception that I was "just another disruptive child".
In retrospect, it troubles me that there was not a protocol before and after I was diagnosed. However, at the age of 15, when I was finally armed with a diagnosis, the school had no choice but to allow greater flexibility and a partial lifting of the stigma attached to my behaviour. As a result, this gave my family some time to manage me and prepare for the rapidly diminishing opportunity left for my education.
I believe that my experiences have made me robust. That is not to say that I'm not anxious - far from it - but, in a sense, my childhood conditioned me to expect certain things. Perhaps having been so frequently defined by my errors became my stage for proving those people wrong. And I am always poised with a funny story to tell about just how wrong I can get things.
Sport has been a great way of helping me to self-regulate my ADHD. And although I am now losing my sight, it hasn't stopped me from achieving a place in the Team GB Paralympics team. I aim to compete in Brazil in 2016.
