english: But in patients with Alzheimer's disease, amyloid-beta builds up and aggregates in the spaces between the brain's cells, instead of being cleared away  like it's supposed to be, and it's this buildup of amyloid-beta that's thought to be one of the key steps in the development of that terrible disease.
non_english: Kod obolelih od Alchajmerove bolesti amiloid-beta se nagomilava u međućelijskom prostoru mozga umesto da se ukloni kao što bi trebalo, te se smatra da je ovo nagomilavanje amiloid-bete jedan od ključnih koraka u razvoju ove strašne bolesti.
