Executive functioning is more than just being about tasks, there are so many other things things the brain controls. I was diagnosed with ADHD several years ago in my 30s. I just thought (as did everyone else) that I was simply a useless, failure of a person who wasn't able to do things and behave the way people are expected to.
I have done so many stupid things over my life, sometimes the same stupid thing several times over, because I have very little impulse control - executive dysfunction.
I get incredibly emotional over silly things and make an absolute tit of myself or get overly dramatic about a small change to my plans because I struggle to regulate my emotions - executive dysfunction.
I have hardly any working memory. I'll have to stop in the middle of a sentence because I have no idea what the topic of conversation is anymore, I forget what I said we were having for dinner 4 minutes ago, and this can happen several times. But I can tell you all about the layout of a flat my family lived in when I was 2, a dream I had when I was 6, the full names and seating arrangements of all my colleagues from a job I haven't been in for 13 years- executive dysfunction.
I was unpacking after a holiday and DP came in and asked me to help him with something straight away. I couldn't do it. I cannot switch tasks without preparation - executive dysfunction.
I can see the kitchen needs cleaning. It is a mess. There are no clean plates. The time is 10:03. I cannot start at 10:03, I will start at 10:15. 10:15 then feels too soon. I will start at 10:30. I check the time, and it is 10:33. I can't start now, I'll have to wait until 10:45. At 10:45 I become paralysed and can't move. Maybe at 11:00. 11:00 - still can't move. Tell myself that 15 minute increments is ridiculous. 12:00 is a perfectly good time. 12:00 - nope.. 12:30 - I develop a burning desire to remove the radiator cover and clean down the back of it with my new crevice cleaners... 13:30 - no point doing it now, maybe I should have lunch. Can't have lunch as it means I'll have to tidy the kitchen first... And this will go on and on. Executive dysfunction.
I personally love the language around it because I hope it might show people that it is an actual neurological disorder. I'm not lazy, I'm not scatty, I'm not stupid, I'm not making excuses - my brain is just not wired the same way. Even medicated, my ADHD is still crippling, and it affects every single area of my life.
