Áttörést jelentő kezelést fejlesztenek Alzheimer-kórra
Alacsony intenzitású ultrahanggal ért el sikert egy nemzetközi kutatócsoport a kognitív képességek helyreállításában, ami áttörést hozhat például az Alzheimer-kór nem invazív kezelésében.
A Queenslandi Egyetem által június végén nyilvánosságra hozott kutatás szerint az új terápia legyőzheti az öregedés és a demencia káros hatásait. A kutatók egérkísérlettel igazolták az alacsony intenzitású ultrahang kedvező terápiás hatását. Tanulmányukat a Molecular Psychiatry folyóiratban publikálták.
"Hagyományosan az ultrahangot kis, gázzal töltött buborékokkal együtt alkalmazzuk, hogy megnyissuk a szinte átjárhatatlan vér-agy gátat, és a véráramból bejuttathassuk a hatóanyagot az agyba" - magyarázta Jürgen Götz professzor, a kutatás vezetője.
Az ultrahang egyedüli alkalmazása elkerülhetővé tette, hogy át kelljen hatolni a vér-agy gáton, nagyobb hozzáférhetőséget és kevésbé invazív kezelési módot nyújtott.
Jelenleg a demencia kezelésében a tüneti kezelés áll az előtérben, de az új módszer lehetőséget nyújt rá, hogy a probléma gyökeréhez jussanak el.
Jürgen Götz hangsúlyozta, hogy a felfedezett ultrahangos terápia egy olyan nem invazív módszer, amely segíthet az idős emberek kognitív képességeinek javításában. Nemcsak a demencia degeneratív hatásait képes csökkenteni, hanem helyre is tudja állítani a kognitív funkciót az időseknél.
A felfedezést klinikai vizsgálatokkal is tesztelik majd.
