Also, regarding how sufferers maintain a professional life: not every sufferer is affected by symptoms the same way. Like with any condition,they will vary per individual.
Individuals have different coping mechanisms and management techniques but they're not infallible and often depend on a series of circumstances that have to be lined up in advance. Imagine following a flow chart.
Some of it will be automatic for people and getting ready for work is more likely to lead to automatic behaviour, because its a set routine which doesn't vary in place, transport or time.
Social engagements are harder for individuals with adhd because none of the variables will be static. Unless you're doing exactly the same thing with the same person, every week...Even then a flaw in the "getting ready" routine can become automatic leading to a consistently late arrival of X minutes each time.
There are 3 main types of adhd as well, and it's worth being aware of this because they indicate how an individual might be affected. Women and girls are also affected differently to men and boys and are better at adapting naturally. Until there's a big change or shift in their lives, when the house of cards may come crashing down.
Conversely, the fact that women adapt better naturally means that many women have gone undiagnosed until adulthood. Many people with adhd will be incredibly organised and conscientious at work - they've learned to be. But outside of work, they need to be able to switch off and recharge.
Incidentally, suffers tend to be brilliant in crisis situations and it's where you'll really see a person with adhd shine. One of the reasons for this is that a person with condition is motivated in a different way to neurotypicals and urgency makes their neurochemicals surge which gives them laser focus.
