Alzheimer hastal\u0131\u011f\u0131n\u0131n erken te\u015fhisi, t\u0131bb\u0131n en zorlu alanlar\u0131ndan biri olmaya devam ediyor. Ancak bilim insanlar\u0131 bu konuda dikkat \u00e7ekici bir ad\u0131m att\u0131. Yeni geli\u015ftirilen burun s\u00fcr\u00fcnt\u00fcs\u00fc testi, hastal\u0131\u011f\u0131n erken i\u015faretlerini, d\u00fc\u015f\u00fcnme ve haf\u0131za sorunlar\u0131 ortaya \u00e7\u0131kmadan \u00f6nce tespit etme potansiyeline sahip.

Alzheimer, haf\u0131zay\u0131, d\u00fc\u015f\u00fcnme becerilerini ve g\u00fcnl\u00fck ya\u015fam\u0131 s\u00fcrd\u00fcrme kapasitesini zaman i\u00e7inde zay\u0131flatan ilerleyici bir hastal\u0131k. Ancak hastal\u0131k \u00e7o\u011fu zaman belirtiler belirgin hale geldikten sonra fark ediliyor. Bu da tedavi ve m\u00fcdahale a\u00e7\u0131s\u0131ndan zaman kayb\u0131na yol a\u00e7abiliyor.<\/p>\n\n\n\n

Yeni geli\u015ftirilen testin dikkat \u00e7ekmesinin nedeni de tam burada ortaya \u00e7\u0131k\u0131yor: Beyindeki hasar b\u00fcy\u00fcmeden \u00f6nce alarm verebilmesi.<\/p>\n\n\n\n

22 Ki\u015finin \u00f6rnekleri incelendi<\/strong><\/h2>\n\n\n\n

Ara\u015ft\u0131rmada bilim insanlar\u0131, burnun \u00fcst b\u00f6l\u00fcm\u00fcnden olduk\u00e7a nazik bir s\u00fcr\u00fcnt\u00fc y\u00f6ntemiyle koku alg\u0131s\u0131yla ba\u011flant\u0131l\u0131 sinir h\u00fccrelerini toplad\u0131. Daha sonra bu h\u00fccreler laboratuvarda incelendi.<\/p>\n\n\n\n

\u00c7al\u0131\u015fmada toplam 22 kat\u0131l\u0131mc\u0131n\u0131n \u00f6rnekleri kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131. Bunlar aras\u0131nda hen\u00fcz belirgin \u015fikayeti olmayan ama laboratuvar bulgular\u0131nda erken i\u015faretler ta\u015f\u0131yan ki\u015filer de yer ald\u0131.<\/p>\n\n\n\n

Elde edilen sonu\u00e7lar, erken evre Alzheimer riski ta\u015f\u0131yan veya hastal\u0131k tan\u0131s\u0131 alm\u0131\u015f ki\u015filer ile sa\u011fl\u0131kl\u0131 bireyler aras\u0131nda belirgin farkl\u0131l\u0131klar oldu\u011funu g\u00f6sterdi. Ara\u015ft\u0131rmac\u0131lar, bu testin sadece dolayl\u0131 i\u015faretleri de\u011fil, ayn\u0131 zamanda canl\u0131 sinir ve ba\u011f\u0131\u015f\u0131kl\u0131k sistemi aktivitelerini de incelemesi nedeniyle \u00f6zel bir \u00f6neme sahip oldu\u011funu vurguluyor.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Uzmanlar\u0131n vurgulad\u0131\u011f\u0131 nokta \u015fu: Bug\u00fcn kullan\u0131lan baz\u0131 kan testleri Alzheimer ile ili\u015fkili i\u015faretleri g\u00f6sterebiliyor, ancak bunlar\u0131n bir k\u0131sm\u0131 daha ge\u00e7 d\u00f6nemde ortaya \u00e7\u0131kan de\u011fi\u015fiklikleri yakal\u0131yor. Yeni burun testi ise hastal\u0131kla ba\u011flant\u0131l\u0131 de\u011fi\u015fimlere daha erken ve daha do\u011frudan bakma ihtimali sunuyor.<\/p>\n\n\n\n

Koku alma duygusu bitiriyor<\/strong><\/h2>\n\n\n\n

Ara\u015ft\u0131rman\u0131n en dikkat \u00e7ekici y\u00f6nlerinden biri, koku alma duyusuyla Alzheimer aras\u0131ndaki ili\u015fkiye dayanmas\u0131. Uzmanlara g\u00f6re koku kayb\u0131, bunama belirtileri ortaya \u00e7\u0131kmadan y\u0131llar \u00f6nce g\u00f6r\u00fclebilen \u00f6nemli i\u015faretlerden biri olabiliyor. Hatta baz\u0131 vakalarda bu de\u011fi\u015fimin, di\u011fer belirtilerden yakla\u015f\u0131k 10 y\u0131l \u00f6nce ortaya \u00e7\u0131kabildi\u011fi belirtiliyor.<\/p>\n\n\n\n

Bu nedenle burnun i\u00e7 k\u0131sm\u0131ndaki koku alg\u0131layan sinir dokusunun incelenmesi, Alzheimer riskini \u00e7ok daha erken d\u00f6nemde anlamak i\u00e7in yeni bir pencere a\u00e7abilir.<\/p>\n\n\n\n

Ara\u015ft\u0131rmac\u0131lar, bug\u00fcne kadar Alzheimer hakk\u0131nda elde edilen bilgilerin b\u00fcy\u00fck \u00e7o\u011funlu\u011funun otopsi dokular\u0131ndan geldi\u011fini belirtiyor. Ancak art\u0131k ya\u015fayan sinir dokusunu inceleyebilmek, tan\u0131 ve tedavi a\u00e7\u0131s\u0131ndan yeni f\u0131rsatlar sunabilir.<\/p>\n\n\n\n

Alzheimer\u2019da \u00f6zellikle tau ve amiloid beta ad\u0131 verilen proteinlerin beyinde anormal \u015fekilde birikmesi b\u00fcy\u00fck \u00f6nem ta\u015f\u0131yor. Bu birikimler sinir h\u00fccrelerinin i\u015fleyi\u015fini bozuyor ve zamanla hastal\u0131\u011f\u0131n ilerlemesine katk\u0131da bulunuyor.<\/p>\n\n\n\n
