Researchers published what they say is the first case of a living person diagnosed with the degenerative brain disease chronic traumatic encephalopathy or CTE.While unnamed in the study, lead author Dr. Bennet Omalu confirmed to CNN that the subject of the case was former NFL player Fred McNeill -- who died in 2015.Omalu is credited with first discovering CTE in professional football players. Until now, the only way to diagnose the disease is with a brain exam after death.The diagnosis was first made using an experimental brain scan that can trace a signature protein of CTE called tau. The authors then confirmed the diagnosis with an autopsy. The case study was published in the journal Neurosurgery this week.'It looked like just depression'Omalu first presented these findings exclusively to CNN's chief medical correspondent, Dr. Sanjay Gupta, in 2016. McNeill's wife, Tia, and his two sons, Gavin and Fred Jr., told Gupta then that they saw Fred transform from a fun loving family man at the center of their lives into a man who was dealing with symptoms of memory loss, anger and depression that tore their family apart."There are some times where the father is the stronghold in the family, or the anchor. If you lose that, everything kind of falls apart. That's kind of what happened for us. It looked like financial issues at first; it looked like marital issues, and they separated; then it looked like just depression," Gavin told Gupta.CTE is known for plaguing people with Alzheimer's like symptoms such as memory loss, rage, mood swings, and in some cases, suicidal ideation.Severity of the disease is categorized into four stages, with stage 4 being the most severe. While researchers don't know exactly why certain people develop the disease and others don't, they believe that it results from repeated blows to the head that trigger a build up of tau proteins in the brain.CTE has been called football's "concussion crisis," however experts point out that CTE can develop from any repeated head injury. According to the Boston University CTE Center, "this trauma includes both concussions that cause symptoms and subconcussive hits to the head that cause no symptoms." These subconcussive hits can include the repeated trauma the brain experiences from constant plays, hitting the turf, and tackling. Wrestlers, boxers, and military troops have also been diagnosed with the disease.Seeing CTEWhile McNeill is the first case to be confirmed with an autopsy, the experimental technology has been used on at least a dozen other former NFL players, including Pro Football Hall of Famer, Dallas Cowboy Tony Dorsett. Omalu helped develop and is invested in the diagnostic exam, which uses a radioactive "tracer" called FDDNP to bind to tau proteins in the brain. The tau proteins can then be seen on a PET scan of the brain.Critics have said the protein also can highlight another protein called amyloid, which may be indicative of Alzheimer's or other forms of dementia. But Omalu noted that in CTE, tau makes distinctive patterns in the brain. It has a "specific topographic signature," he said, and that pattern can be detected in imaging.Omalu said he and his team are currently raising money to start a phase 3 clinical trial to further test the technology and replicate what they have seen in McNeill. He anticipates that once funds are raised, it will take another two to three years for the trial and then another year, at least, for approval from the US Food and Drug Administration. When asked, how soon a commercial test could be available, Omalu predicted it could be as soon as a few years. "We are looking at less than five years," he said.  3711

Puerto Rico was hit with a massive power outage, the power authority said Thursday -- nearly seven months after Hurricane Maria destroyed much of the island's infrastructure and its electrical grid.The Puerto Rico Electric Power Authority, known as PREPA, said a tree fell on a major power line, knocking out service to 870,000 customers, about half of its clients. The utility tweeted an image it says was of the tree that fell across a power line near the southeast mountain town of Cayey.Major blackouts were reported from the northern coastal town of Manatí to Yabucoa, roughly 50 miles southeast.The blackout also includes the capital of San Juan, the most populated area of the island."We are devastated at this point," Cynthia García Coll, an educational psychologist who lives near San Juan, told CNN. "Every time this happens we go into PTSD mode."San Juan Mayor Carmen Yulín Cruz said it could take eight to 16 hours for electricity to be restored. 966

Republican Kim Davis, the Kentucky court clerk who became a conservative Christian heroine for refusing to sign same-sex marriage certificates three years ago, lost her re-election bid Tuesday, according to unofficial results posted by the Kentucky State Board of Elections.Democrat Elwood Caudill Jr. appeared to defeat Davis by more than 650 votes in the race for clerk in Rowan County, according to the unofficial results, with all precincts reporting. "She congratulated me, told me we done a great job, and I thanked her, told each other we loved each other," Caudill told CNN affiliate WKYT, after he said Davis called him to concede.Davis spent several days in jail in September 2015 after refusing to abide by that summer's historic US Supreme Court ruling that legalized same-sex marriage."It is not a light issue for me. It is a heaven or hell decision," Davis said in a statement at the time, citing her religion.A federal court judge declared Davis in contempt of court for refusing to issue the licenses and not allowing her six deputy clerks to issue them in her place. US District Court Judge David Bunning ordered that Davis remain behind bars until she complied.Five of her deputies then agreed to issue marriage licenses in her absence, and the Rowan County Clerk's Office also began doing so.The judge ordered her release days later, saying he was satisfied the office was issuing marriage licenses to "legally eligible couples."A few years before the Supreme Court ruling, Davis had converted to Apostolic Christianity, a faith which has a strict moral code, her attorney said at the time.Davis later had a private meeting with Pope Francis in Washington during his first US visit in 2015. 1717

President Donald Trump tweeted on Wednesday that his administration is not considering renaming military bases named after 10 Confederate military leaders.Earlier in the week, amid national unrest over police brutality against African Americans, and racial injustice, the Defense Department said it was open to discussions on renaming the bases. The announcement came as a number of local leaders have announced the removal of statues of Confederate military leaders from a number of public plazas.But Trump closed that door on Wednesday.The tweets read, “It has been suggested that we should rename as many as 10 of our Legendary Military Bases, such as Fort Bragg in North Carolina, Fort Hood in Texas, Fort Benning in Georgia, etc. These Monumental and very Powerful Bases have become part of a Great American Heritage, and a history of Winning, Victory, and Freedom.“The United States of America trained and deployed our HEROES on these Hallowed Grounds, and won two World Wars. Therefore, my Administration will not even consider the renaming of these Magnificent and Fabled Military Installations. Our history as the Greatest Nation in the World will not be tampered with. Respect our Military!”The Confederate government symbols have become a point of contention among supporters of Black Lives Matter, and that the Confederate leaders led a government to preserve slavery in the South. 1402

RAINBOW, Calif. (KGTV) - A new overpass may be destined for the I-15, not for people but mountain lions.A just-released study led by The Nature Conservancy and backed by the National Park Service recommended a stretch of the I-15 just south of Temecula - either an overpass or underpass like crossings in Colorado, Utah and Wyoming - allowing mountain lions and other wildlife to safely get across.On the west side of the highway is preserve space owned by San Diego State University.  On the other side are 73 acres just purchased by The Nature Conservancy.  Experts says the local mountain lions have been cut off by the freeways and are practicing inbreeding."That makes them more susceptible to disease, and that could be catastrophic for the mountain lion population," said Cara Lacey, an associate program director at The Nature Conservancy.Lacey points out crossings in other states have also cut down on vehicle collisions with wildlife.  She says at least three mountain lions were struck by vehicles in that stretch of I-15 in 2017.  Caltrans is studying a crossing on Highway 101, which would cost between and million. 1165
