It seemed like Robin Williams almost changed overnight.
Prior to his sudden death in 2014, Williams & Friends and colleagues knew he was conducting an internal fight.
He could not remember his lines. He thought he was not funny anymore. He cried uncontrollably.
"He was sobbing in my arms at the end of each day, it was awful, terrible," recalls makeup artist Cheri Minns. I said to his people: I'm a make-up artist. I do not have the ability to deal with what happens to him.
To help, Minns Williams suggested returning to the stand-up comedy.
"He just cried and said," I can not, Cheri, I do not remember how, I can not be funny . "
Dave Hughes likes to sober himself. Post goes on.
At the time, Williams had no idea that he was suffering from a pernicious neurodegenerative disease that was slowly eroding his mind.
Basically, he deprived Williams of everything that made him Robin Williams.
A New Biography Robin written by Dave Itzkoff, Williams has told us last days.
It shows Williams & # 39; s stellar comedy and acting career in which it seemed like he could not go wrong, and then his slow decline in the zeroes.
In 2013, Williams returned to the small screen co-starting in CBS The Crazy with Sarah Michelle Geller.
But the magic was not there and the critics popped the show all around.
At the time, the people close to him noticed a change in Williams. He began to complain about insomnia, indigestion, he said he had difficulty urinating, he was afraid that he had lost his sense of smell. There was also a slight tremor in his left hand.
His third wife, Susan Schneider, described his deteriorating health in Robin .
"It was like being a mole, which symptom is it this month? I thought, my husband is a hypochondriac We're chasing it and there are no answers, and we've tried everything by now."
As CBS canceled after just one season The Crazy Ones William's friends thought he was depressed. His longtime friend Billy Crystal said he was a changed man.
In May 2014, Williams was diagnosed with Parkinson's disease.
He checked himself into a rehab center, but he would never be the same again.  He had a slow, shuffling gait. He hated that in conversation he could not find the words he wanted. He hit at night and still had terrible insomnia. Sometimes he was stuck in an icy position, unable to move, and frustrated when he came out. He started having problems with the visual and spatial abilities, judging distance and depth. His loss of keynotes contributed only to his growing confusion, "Susan once wrote in the journal Neurology .
In August 2014, Williams said goodbye to Susan and said goodbye to his room.
" As We always did that, we said to each other, "Good night, my dear," Susan said.
"He seemed to feel better, as if he was on the way of something."
The next morning, Susan discovered that Williams had committed suicide.
Three months later, the autopsy revealed that the veteran comedian was suffering from "diffuse Lewy body dementia".
He was not depressed and had no Parkinson's disease incurable brain disease, Williams had slowly deprived of his vitality.
Lewy body dementia, also known as dementia with Lewy bodies, is a progressive brain disease characterized by microscopic protein deposits called Lewy bodies and develops in the brain. It is the second most common form of dementia, but it is often misdiagnosed as Parkinson's disease or Alzheimer's. Symptoms include sleep disturbances, hallucinations, movement disorders, difficulty in judging distances, confusion and memory loss.
It's fast-paced, and one patient diagnosed with Lewy dementia has about seven years to live after the onset of symptoms, according to Alzheimer's Australia
"It was not the depression that killed Robin," Susan told People . "Depression was one of the 50 symptoms, and it was a small one."
