alzheimer disease devastate type dementia account 60 80 percent dementia case currently affect million americans accord alzheimer association 6th lead cause death unite state someone u.s. develop disease every 66 second 2050 number case project reach 13.8 million.scientists researchers grapple understand disease search cure since 1906 german neurologist dr. alois alzheimer discover plaques tangle brain woman die unknown mental illness symptoms memory loss difficulty language erratic behavior progression disease amyloid plaque deposit neurofibrillary tangle build brain disrupt connections nerve cells ultimately death nerve cells brain tissue.a recent study lead scientists university glasgow scotland hong kong university science technology produce potential breakthrough alzheimer disease treatment.in mice progressive disease similar alzheimer researchers inject protein call il-33 within week memory cognitive function affect mice improve normal level daily protein injections clear exist amyloid plaque brain mice stop development result yet test humans guarantee protein similar result human trials 2014 study estimate positive result experiment mice translate success humans rate percent.nonetheless study promise cure treatment currently available alzheimer disease alzheimer care form dementia estimate cost unite state 236 billion 2016.working mice scottish chinese researchers find protein il-33 promote development microglia immune cells brain direct towards plaque form alzheimer disease relevance find human alzheimer present unclear encourage hint say professor eddy liew lead researcher study university glasgow press release example previous genetic study show association il-33 mutations alzheimer disease european chinese populations furthermore brain patients alzheimer disease contain less il-33 brain non-alzheimer patients enough false breakthroughs medical field caution us hold breath rigorous clinical trials do researchers soon begin first phase clinical trials humans test toxicity protein il-33 dose use mice global medical community anticipate hope favorable results.featured image courtesy flickr new study offer hope search alzheimer cure
