Scientists の近くに in on 血 実験（する） for Alzheimer's: Six 研究 groups 報告（する）／憶測 重要な 進歩 - with up to 88% 正確 at spotting the 病気

• e-mail

Scientists are の近くにing in on a long-sought goal - a 血 実験（する） to 審査する people for possible 調印するs of Alzheimer's 病気 and other forms of dementia.

On Monday at the Alzheimer's 協会 International 会議／協議会, half a dozen 研究 groups gave new results on さまざまな 実験の 実験（する）s, 含むing one that seems 88 パーセント 正確な at 示すing Alzheimer's 危険.

Doctors are hoping for something to use during 決まりきった仕事 exams, where most dementia symptoms are 評価するd, to 計器 who needs more 広範囲にわたる 実験（する）ing.?

現在の 道具s such as brain ざっと目を通すs and spinal fluid 実験（する）s are too expensive or impractical for 正規の／正選手 check-ups.

'We need something quicker and dirtier. It doesn't have to be perfect' to be useful for 審査, said Maria Carrillo, the Alzheimer's 協会's 長，指導者 science officer.

Dr Richard Hodes, director of the 国家の 学校／設ける on 高齢化, called the new results 'very 約束ing' and said 血 実験（する）s soon will be used to choose and 監視する people for federally 基金d 熟考する／考慮するs, though it will take a little longer to 設立する their value in 決まりきった仕事 医療の care.

'In the past year we've seen a 劇の acceleration in 進歩' on these 実験（する）s, he said. 'This has happened at a pace that is far faster than any of us would have 推定する／予想するd.'

Dr Jori Fleisher, a neurologist, 診察するs Thomas Doyle, 66, at the 急ぐ University 医療の 中心 in Chicago. Doyle, 66, hopes 血 実験（する）s may someday 取って代わる the invasive diagnostic 実験（する）ing he 耐えるd to be 診断するd 4.5 years ago with Lewy 団体／死体 dementia

It can't come too soon for 患者s like Tom Doyle, a 66-year-old former university professor from Chicago who has had two spinal fluid 実験（する）s since developing memory problems four years ago.?

First he was told he didn't have Alzheimer's, then that he did. He 最終的に was 診断するd with different problems - Lewy 団体／死体 dementia with Parkinson's.

'They probably could have 診断するd me years ago 正確に if they had had a 血 実験（する）,' said Doyle, who 代表するs 患者s on the Alzheimer's 協会's board.

About 50 million people 世界的な have dementia, and Alzheimer's is the most ありふれた form.?

There is no cure; 現在の 薬／医学s just 一時的に 緩和する symptoms. Dozens of hoped-for 治療s have failed.?

Doctors think 熟考する／考慮するs may have 入会させるd people after too much brain 損失 had occurred and 含むd too many people with problems other than Alzheimer's.

A 血 実験（する） - rather than subjective 見積（る）s of thinking 技術s - could get the 権利 people into 熟考する／考慮するs sooner.

One of the 実験の 血 実験（する）s 対策 異常な 見解／翻訳／版s of the protein that forms the plaques in the brain that are the hallmark of Alzheimer's.?

Last year, Japanese 研究員s published a 熟考する／考慮する of it and on Monday they gave results from validation 実験（する）ing on 201 people with Alzheimer's, other types of dementia, 穏やかな impairment or no symptoms.

The 血 実験（する） results closely matched those from the 最高の，を越す 実験（する）s used now - three types of brain ざっと目を通すs and a mental 査定／評価 exam, said Dr. Akinori Nakamura of the 国家の 中心 for Geriatrics and 老年学 in Obu, Japan.?

The 実験（する） 正確に identified 92% of people who had Alzheimer's and 正確に 支配するd out 85% who did not have it, for an 全体にわたる 正確 of 88%.

Shimadzu Corp. has 権利s to the 実験（する） and is working to commercialize it, Nakamura said.

Another 実験の 実験（する） looks at neurofilament light, a protein that's a marker of 神経 損失. Abdul Hye of King's College London gave results of a 熟考する／考慮する comparing 血 levels of it in 2,300 people with さまざまな neurological 条件s - Alzheimer's, other dementias, Parkinson's, 不景気, 多重の sclerosis, Lou Gehrig's 病気 - 加える healthy folks for comparison.

Levels were 意味ありげに higher in eight 条件s, and only 2% of healthy folks were above a threshold they 始める，決める for raising 関心. The 実験（する） doesn't 明らかにする／漏らす which disorder someone has, but it may help 支配する one out when symptoms may be psychological or 予定 to other problems.

Later at the 会議／協議会, Dr. Randall Bateman of Washington University School of 薬／医学 in St. Louis will give new results on a 血 実験（する） he helped develop that the university has 特許d and licensed to C2N Diagnostics, a company he co-設立するd.?

Like the Japanese 実験（する）, it 対策 the 異常な Alzheimer protein, and the new results will show how 井戸／弁護士席 the 実験（する） 反映するs what brain ざっと目を通すs show on nearly 500 people.

'Everyone's finding the same thing ... the results are remarkably 類似の across countries, across techniques,' said Bateman, whose work is supported by the U.S. 政府 and the Alzheimer's 協会. He 見積（る）s a 審査 実験（する） could be as の近くに as three years away.

What good will that do without a cure?

An Associated 圧力（をかける）-NORC 中心 for Public 事件／事情／状勢s 研究 投票 last year 設立する that most Americans would want to know if they carried a 遺伝子 tied to a 病気 even if it was incurable.

'What people want most of all is a diagnosis' if they're having symptoms, said Jonathan Schott of University College London. 'What we don't like is not knowing what's going on.'
