纽约市发生一起办公室枪击案，嫌犯 Shane Tamura 造成四人死亡，随后自杀。警方在其身上发现的笔记中，嫌犯声称自己患有慢性创伤性脑病（CTE），并要求研究其大脑。笔记中提及了NFL，纽约市长 Eric Adams 表示，嫌犯可能误入NFL办公室所在的楼层，意图针对NFL。CTE是一种与反复头部撞击相关的脑部疾病，常见于橄榄球等接触性运动运动员，可能导致认知功能和情绪改变。

🎯 纽约办公室枪击案嫌犯 Shane Tamura 在其随身携带的笔记中声称患有慢性创伤性脑病（CTE），并要求死后研究其大脑。这一发现将枪击事件的动机与一种已知与反复头部撞击相关的脑部疾病联系起来。

🏈 笔记中提及了NFL（美国国家橄榄球联盟），纽约市长 Eric Adams 指出，嫌犯可能误入了位于同一栋大楼的NFL办公室，并推测其可能意图针对NFL。该枪击事件发生在345 Park Avenue，该地址是Blackstone、NFL和KPMG的办公地点。

🧠 慢性创伤性脑病（CTE）是一种脑部疾病，通常在经历过反复头部损伤的人群中诊断，包括一些NFL球员。研究表明，反复的非击晕性头部撞击会损害神经细胞，严重影响认知功能和情绪，可能导致记忆丧失、决策能力下降、焦虑、抑郁、性格改变和冲动等症状。

⚠️ CTE的症状会随着时间推移而发展，可能需要数年才能显现，目前尚无治愈方法，也无法在生前确诊（需要死后大脑分析）。然而，有药物和疗法可以帮助管理疑似CTE患者的症状。接触性运动如橄榄球、综合格斗和橄榄球是CTE的风险因素，某些军事角色也可能增加风险。

⚖️ CTE已成为职业体育联盟（如NFL）中的一个争议性话题，并与一些前职业运动员的突然死亡或暴力犯罪事件相关联。例如，前NFL球员 Phillip Adams 在2021年枪杀六人后自杀，Aaron Hernandez 在被定罪谋杀后死于自杀，死后被诊断出患有严重的CTE。

Shane Tamura, suspected of shooting four people in New York City on Tuesday, claimed in a note that he had CTE.The note found in his pocket referenced the NFL, and asked for his brain to be studied.CTE is associated with being repeatedly hit in the head.

A man who opened fire in a New York City office, killing four people and wounding others before turning the gun on himself, carried a note claiming to have a traumatic brain injury, authorities said.

The shooter was identified as 27-year-old Shane Tamura.

A note found in his pocket stated that he suffered from CTE (chronic traumatic encephalopathy), and asked that his brain be studied. His note made references to the NFL, New York City Mayor Eric Adams said.

"He seemed to have blamed the NFL," Adams in a press conference, ESPN reported. "The NFL headquarters was located in the building, and he mistakenly went up the wrong elevator bank."

The incident occurred at 345 Park Avenue, a building which houses Blackstone, the NFL, and a KPMG office.

What is CTE?

CTE is a brain disorder that has been diagnosed in people who have suffered repeated head injuries, including some NFL players.

Brain researchers believe repeated, subconcussive hits to the head can damage nerve cells, causing serious disruption to cognitive function and mood.

Symptoms of CTE include memory loss, impaired decision making, anxiety, depression, personality changes, and impulsiveness.

The condition progresses over time, and can take years to develop.

There is no cure and there is no way to definitively diagnose CTE during life (it requires posthumous analysis of the brain).

However, there are medications and therapies that may help manage symptoms in people suspected to have CTE.

CTE is a hot-button topic in football

Contact sports like football, mixed martial arts, and rugby are a risk factor for CTE since they involve recurring impacts to the head, research shows. People in certain military roles, such as those routinely firing heavy weapons, also have a higher a risk of CTE.

The brain disease has become a controversial topic in professional sports leagues such as the NFL.

CTE has been identified in high-profile incidents involving former pro athletes who have died suddenly or committed violent crimes.

Ex-NFL player Phillip Adams who shot and killed six people and then himself in 2021. New England Patriots tight end Aaron Hernandez was convicted a murder before his death by suicide at 27 years old. He was posthumously diagnosed with the worst case of CTE researchers had ever seen.

The shooter may have been targeting the NFL, Mayor Adams said

The NFL did not immediately respond to a request for comment from Business Insider.

Tamura, the suspect in the recent NYC shooting, was a football player in high school, and mentioned the NFL in the note, the police said.

New York City Mayor Eric Adams said in a press conference that authorities believe the shooter was trying to reach the NFL offices but reached the wrong floor.
