On Thursday his wife released a statement that he had been diagnosed with Parkinson's Disease and was in the early stages, it's a nasty degenerative neuro/motor problem that makes any physical activity increasingly difficult. Michal J. Foxx has it, I remember one story where he was being taken to an awards show in a limo and had the driver circle the block several times because he couldn't stop his shaking, this was before he made his condition public.
I have a similar problem called Essential Tremors where my body (mainly my back, sometimes my head/hands/arms) sometimes shake uncontrollably and had an idiot of a doctor who said I probably had Parkinson's in an off-cuff comment as he was leaving the exam room, I never saw him again. The main source of the problem was hyperparathyroidism which was fixed surgically, but it persists even though my parathyroid is back to normal. Normally my tremors are a telegraph/warning that I'm getting sick, but it can also be stress-related (and my cataract surgery has been hugely stressful!)
So for me, a Parkinson's diagnosis is never far from my mind. The sad thing is that Parkinson's is bad, but it's not fatal. But there's usually more than one dimension when someone takes their own life, and Robin Williams was obviously a very complex character.

This item I did not know, my wife told me about it a couple of days ago and it never hit my normal news sources: a bunch of people started essentially tormenting his daughter Zelda on Twitter, so much that she has closed her account for now and Twitter has banned a number of people for their actions. It never ceases to amaze me the level of rectal haberdashery that people can descend to online in the very thin guise of pseudo-anonymity. Would these people walk up to her on the street and mock her pain, shoving Photoshopped pictures of her dad's suicide in her face? Some of them, the true sociopaths, yes. Most would not. But online no can can see that you're a dog, and they take that as a license to be asses.
