Stephen Paddock, the 64-year-old gunman who killed 58 concertgoers in Las Vegas final October within the worst mass taking pictures in fashionable American historical past, had not had a stroke, mind tumor or a lot of different neurological issues that may have helped clarify his actions, a latest examination of the stays of his mind confirmed.

Mr. Paddock’s mind did have modifications generally seen in Individuals of his age, together with proof of atherosclerosis — fatty plaques inside blood vessels that may impair circulation, which mind cells depend on to outlive. Scattered on the surfaces of his mind had been an abnormally excessive variety of tiny deposits that have a tendency to extend with age and accompany some neurological ailments.

The mind examination was performed by Dr. Hannes Vogel, the director of neuropathology at Stanford College. Dr. Vogel mentioned he was capable of carry out an satisfactory analysis, regardless of harm attributable to Mr. Paddock’s deadly, self-inflicted gunshot wound to the pinnacle.

“With a great deal of screening, I didn’t see something,” he mentioned, that might clarify why Mr. Paddock grew to become a calculating mass killer.

Though consultants had thought of it unlikely mind examination would offer solutions to what led Mr. Paddock, to commit a mass taking pictures, docs all through the nation had proposed ruling out greater than a half-dozen issues that may probably be implicated. Dr. Vogel discovered none of them.

There was no proof of frontotemporal lobar degeneration, which impacts “government capabilities,” together with decision-making and social interactions, and may trigger character modifications and unrestrained habits. That illness would seemingly have been inconsistent with somebody capable of have interaction in meticulous planning.

Mr. Paddock had complained to buddies of feeling ailing, in ache and fatigued, in response to a preliminary report on the police investigation launched final month. Mr. Paddock’s girlfriend, Marilou Danley, advised investigators that he had grown extra distant over the yr earlier than the taking pictures. The legislation enforcement report described Mr. Paddock as “germaphobic” and strongly reactive to smells.

A major care doctor in Las Vegas — who mentioned he had been Mr. Paddock’s physician since 2009 and had final seen him as a affected person roughly a yr earlier than the taking pictures — advised officers that he suspected Mr. Paddock had bipolar dysfunction. That psychological dysfunction, nevertheless, can’t be recognized in a typical autopsy examination of mind buildings. And whereas some research have proven that individuals with bipolar dysfunction usually tend to have a historical past of violent habits than most of the people, nearly all of them don’t, and the connection between psychological well being and violence entails many different components.

The physician, who was not named within the report, additionally described Mr. Paddock as having behaved oddly, exhibiting little emotion and expressing worry of medicines. Mr. Paddock had refused prescriptions for antidepressants, however the doctor had prescribed anti-anxiety medication for him.

An post-mortem report confirmed he did have anti-anxiety remedy in his system, in response to The Las Vegas Evaluate-Journal, which obtained the report on Friday.

The examination confirmed that the surfaces of Mr. Paddock’s mind contained small spheres which will be seen on sections handled with a stain. The buildings, made up largely of carbohydrates but additionally containing proteins and different elements, are generally known as corpora amylacea. “Most individuals would have them at that age, however not in that profusion,” Dr. Vogel mentioned. “It’s a putting exaggeration of an age-related discovering.”

The trigger and that means of the buildings stay mysterious, the topic of ongoing analysis. They seem as folks get older and are discovered at higher density within the brains of sufferers with Alzheimer’s illness, a number of sclerosis and epilepsy, amongst different issues. Dr. Vogel looked for indicators of these ailments, however he didn’t detect them in Mr. Paddock’s mind.

Three scientists who examine corpora amylacea mentioned in interviews that the elevated presence of the buildings was important. “If in case you have excessive numbers of those, one thing’s not regular,” mentioned Troy Rohn, a professor of biology at Boise State College.

Different scientists consider the buildings are akin to wastebaskets that include remnants of broken-down cells and even hazardous substances.

Dr. Hyman Schipper, a professor of neurology at McGill College in Montreal, mentioned his laboratory’s research have discovered proof that corpora amylacea may result from the harm attributable to unstable molecules generally known as free radicals, which will be unleashed by varied stressors. “It’s telling you one thing and it could possibly be crucial,” Dr. Schipper mentioned of the discovering in Mr. Paddock’s mind.

Even so, Dr. Vogel, the Stanford neuropathologist, mentioned the outcomes of his examination ought to reassure the general public that Mr. Paddock’s docs had not missed diagnosing a tumor or different main mind dysfunction that might have been handled.

The Clark County coroner’s workplace had despatched 129 brains to Stanford for examination earlier than Mr. Paddock’s. Usually they arrive by FedEx, however with heavy public curiosity in Mr. Paddock’s case, the coroner, John Fudenberg, hand-delivered the mind — and Dr. Vogel has been requested to return it in particular person.
