Robin Williams' suicide was triggered by a horrible disease called Lewy Body Dementia ... sources connected with his family tell TMZ.

TMZ has obtained documents showing Williams was struggling with the disease, which is marked by abnormal protein deposits in the brain that disrupt normal function.

Lewy Body Dementia is a condition commonly associated with Parkinson's ... and people afflicted by both often get severe side effects from Parkinson's meds. Hallucinations are common, where patients see phantom objects, people or animals. The patients often try to converse with the illusions.

Robin's wife had told authorities shortly after his death he had been complaining about the meds and the way they made him feel.

Sources connected with the Williams family tell TMZ ... Lewy Body Dementia was the "key factor" they believe drove him to kill himself. We're told Robin's doctors agree that the disease was the critical factor leading to his suicide.

Joan Rivers would be alive today if the clinic where she stopped breathing had a proper crash cart ... sources connected with her family's legal team tell TMZ.

TMZ broke the story ... there were a number of screw ups, including doctor's notes that showed an alarming amount of Propofol in her body. We're told the notes were not accurate and there was nothing in the blood work to suggest Propofol killed Joan.

But the legal team believes the Yorkville Endoscopy Center did not have critical lifesaving equipment on the crash cart ... specifically a drug called Succinylcholine, used to relax a patient's trachea. The legal team believes Joan's vocal chords spasmed and closed shut. The drug would have instantly opened them.

To make matters worse ... the legal team says the doctors were asleep at the wheel, failing to identify "deteriorating vital signs."

Kyle Richards and her daughter Alexia Umansky were out and about Monday ... the first time the 18-year-old has been seen in public since she was viciously attacked by her aunt's pit bull.

Kyle and Alexia went inside the James Kendall Salon in Bev Hills and had little to say about the dog bite that required 2 surgeries.

Our photog mistakenly asked Alexia if she was mad at "your friend" ... obviously Kim Richards is her aunt, but close enough ... sorta.

Eric Dane is a huge star!

Here's a 31-year-old version of the "Charmed" actor at a fancy Hollywood movie premiere back in 2003 (left) and 11 years later -- the "Grey's Anatomy" hunk -- who celebrates his 42nd birthday this weekend -- at a store opening last month (right).

Nurse!

Ex-NFL player James Hardy III -- a 2nd round draft pick in 2008 -- has been committed to a state mental institution ... 6 months after he was arrested for attacking 3 cops ... TMZ Sports has learned.

We broke the story ... Hardy was taken into custody on May 4th at an L.A. apartment complex after an alleged violent meltdown. We're told it took several officers to subdue the 6'6", 225-pound athlete.

Now, we're told a judge has ruled that Hardy is not mentally competent to stand trial in the case -- and has ordered the 28-year-old to be committed to a state hospital.

According to court documents, the hospital has the authority to administer "involuntary antipsychotic medication" to Hardy as needed.

Amanda Bynes' cry for employment has been answered -- an L.A. bar is offering her a high profile bartending gig ... right in the heart of the Sunset Strip.

Chad Weiner, the managing partner of State Social House in West Hollywood, tells TMZ ... he's got an apron and a bottle opener with Amanda's name on it ... all she needs to do is say yes.

TMZ broke the story ... Amanda wants to live a "normal life," and make some money -- and she thinks bartending is the way to go.

Chad says his spot on the Strip is perfect for Amanda, since his staff knows her and would love to teach her the ropes. As for her schizophrenia ... Chad has a pay it forward attitude -- telling us he'd like to give Amanda a second chance, because he once got one when he was battling substance abuse.

Brian Bosworth himself now says he's a headcase -- the ex-linebacker is going after the NFL for turning his brain to mush ... claiming the league knowingly lied about the dangers of concussions during his 3 seasons.

Brian -- infamously known as "The Boz" during his playing days -- says he suffered multiple concussions that were improperly diagnosed while he played for the Seattle Seahawks in the late 1980s. So he's now filed a lawsuit against the NFL and helmet-maker Riddell.

In the suit, Boz blasts the NFL for concealing the truth about head injuries and the after effects. He's also pissed at the NFL for "glorifying violent plays" with NFL Films projects such as ... "Moment of Impact" and the "Crunch Course" series.

According to the docs, experts have criticized Riddell for making crappy helmets that inadequately protect players. Boz even says they have a design defect.

He adds that he's currently suffering severe headaches and memory loss.

Bosworth's suit is almost a word-for-word copy of the class action lawsuit thousands of ex-NFL players brought against the league ... which was settled in July.

Amanda Bynes has a plan ... she wants to sling drinks.

Sources connected to Amanda tell TMZ ... she wants "a normal life," and she believes working in a bar would achieve that goal.

Amanda says she's well aware of the obvious impediment -- she attracts so much attention it would be hard to function as a bartender.

As for why Amanda is even thinking of getting a job ... she desperately needs money. She doesn't have access to her $5.7 million fortune because of her conservatorship, and only gets between $50 and $100 a day. As for what she wants to do with the money, aside from getting an apartment, she wants plastic surgery because she thinks she's ugly.

We know 2 people from The Canyon Treatment Center -- where Amanda went for rehab -- have reached out to her and offered her a place to stay.

Boxing legend Leon Spinks is finally walking, talking and smiling again ... after a medical scare stemming from a chicken bone accident ... TMZ Sports has learned.

As we previously reported, Spinks was hospitalized -- and was in pretty bad shape -- after swallowing a chicken bone ... which got lodged in his intestine.

We spoke with Leon's attorney Steve Pacitti who tells us the former champ is still in the hospital -- but he's making tremendous progress.

"He's healing. He's on the road to recovery," Pacitti tells TMZ Sports ... "I went to see him the other night and when I walked in he flashed a huge smile. He's in great spirits."

NOFX lead singer Fat Mike was the professor ... an overzealous fan was the student ... and the lesson was pain. SERIOUS PAIN!

Anyone else need to know what happens when you bum rush your favorite punk rock band? Pay close attention to this awesome video!!

"Love & Hip Hop: Hollywood" star Yung Berg allegedly did a real number on his girlfriend -- leaving her with nasty injuries over much of her body when they had a hotel room brawl in NYC.

Masika Tucker told police ... "He hit me and dragged me by my hair. He pinned me to the wall and grabbed me by my throat" -- this according to the criminal complaint obtained by TMZ.

In the docs, Tucker says she suffered a laceration to her right forearm, a laceration above her left eyebrow, bruising to the left side of her neck, and a laceration to her chest.

In all, Berg was hit with four charges -- three assaults and one harassment -- but managed to avoid the "obstruction of breathing" misdemeanor ... which he was initially booked for when he got arrested.

As TMZ first reported, the fight was triggered after Yung Berg's credit card was declined during a night on the town.

After wandering around homeless, Amanda Bynes is in desperate straits ... with no place of her own to live ... Amanda crashed on a sofa in the middle of The Beverly Center in Los Angeles.

We got these pics of Amanda out like a light Thursday morning in the middle of the mega-mall.

It's incredibly sad ... Amanda's parents are moving to Texas and ending their conservatorship over her ... because they're just not equipped to convince their daughter she needs meds and doctors so she can survive.

Amanda was crashing with friends last week, but she's been wandering around the West Hollywood area with no place to go.

She's getting $50 to $100 bucks a day, but it's not enough for her to get a place of her own. She's been staying with friends, but didn't go back to their place last night.

Amanda is complaining she doesn't have enough money to even get a hotel room for a night.

So sad.

NOFX lead singer Fat Mike blasted a concertgoer in the face TWICE Wednesday in Australia ... but the guy isn't planning to sue -- in fact, the young fan is taking the blame.

The famous punk band was playing a gig at the Enmore Theatre in Sydney when an overzealous concertgoer wearing a bucket hat jumped on stage and put his arm around Mike's neck.

The singer had told the crowd earlier in the show he was suffering from neck pain ... so Mike reacted with a spinning forearm to the guy's face -- followed by a punt kick to the head while he was down.

The young fan -- named Alex -- tweeted Mike after the show apologizing ... saying he had been drinking and forgot the singer's neck was hurting.

Kyle Richards' daughter was the victim of a vicious pit bull attack ... a dog owned by Kyle's own sister Kim, and the damage was so severe it required multiple surgeries.

We're told 18-year-old Alexia Umansky spent the weekend at Cedars-Sinai Medical Center, twice going under the knife.

The attack occurred early Saturday at Kim's L.A. area home. Kyle, Alexia and other members of their family had been inside the house for a while ... when the dog went into attack mode out of nowhere.

The dog bit Alexia numerous times, but the worst was on her right hand ... where it bit through her thumb right to the bone.

The pit bull has a history of biting. It attacked its trainer on an episode of "Real Housewives of Beverly Hills" ... and it's also been very aggressive toward other dogs.

Kim is still keeping the animal at her home ... as the Dept. of Animal Control was never called. We're told they wanted to keep the incident "private."

We reached out to Kim and Kyle ... so far, no word back.

One punch ... that's all it took for Princess Love to lay one of her castmates out flat ... during a brawl while taping the "Love & Hip Hop: Hollywood" reunion show.

Production sources tell TMZ ... Morgan Hardman was bad-mouthing Princess' BF, Ray J, while they were filming Monday in NYC ... so Princess allegedly hauled off and decked her ... knocking her flat on her back.

Hardman was telling everyone in earshot that Ray J physically abused her. She went on to say Ray J threw her son off his basketball team out of spite. Ray J fired back ... saying the kid wasn't old enough to be on the team, but will next year. He also said he never laid a hand on Hardman.

Apparently, Princess Love reached her breaking point and cold-cocked her. An ambulance came and paramedics treated her on scene.

Yung Berg -- the rapper who stars on "Love & Hip Hop Hollywood" -- was arrested in NYC early Wednesday for allegedly brutalizing his girlfriend, and the charge is "obstruction of breathing" ... TMZ has learned.

Berg -- aka Hitmaka -- and the woman were at the Gershwin Hotel when they got in an argument ... where he allegedly grabbed her by the neck, threw her to the floor, dragged her by her hair and hit her in the face.

Apparently, the neck grab was enough for the breathing obstruction charge.

When cops came, the woman had bruises and complained she was in pain.

He's currently in custody.
