Alzheimer’s is the most common cause of dementia and, despite its huge impact, there\u2019s still no effective cure. Its impact on society is huge and it has been calculated that, by 2050, the number of cases of Alzheimer’s will have tripled, rising from the current 1.2 cases in Spain to 3.6 million. As the disease advances, there\u2019s progressive neurodegeneration that affects not only memory but also the ability to relate to others and even the individual’s own identity.<\/span><\/p>\n

For years, it was believed that the brain damage associated with Alzheimer’s, especially in the regions essential for memory, only occurred<\/span> when two proteins were present: amyloid beta and tau<\/b>. However, this hypothesis could be about to change.<\/span><\/p>\n

A study by the<\/span> Barcelona\u03b2eta Brain Research Center (<\/b>BBRC<\/b><\/a>)<\/b>, a research centre of <\/span>the Pasqual Maragall Foundation<\/span><\/a>, has discovered that the accumulation<\/span> of amyloid beta can, by itself, cause brain damage in the early stages of the disease<\/b>. This finding, published in the journal <\/span>Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association<\/span><\/i><\/a>, has been made possible thanks to samples of cerebrospinal fluid from 360 <\/span>volunteers from the <\/b>Alfa + cohort<\/b><\/a>, funded by \u201cla Caixa\u201d Foundation,<\/b> as well as the use of high-resolution magnetic resonance imaging.<\/span><\/p>\n

The results suggest that an accumulation of amyloid beta (as seen in the image) may be <\/span>an early indicator<\/b> of structural changes in the brain and of possible deterioration in memory before the appearance of obvious symptoms of the disease. The protein seems to <\/span>directly affect the hippocampus<\/b>, a key region for memory, so that acting on amyloid beta early on could significantly reduce the risks associated with Alzheimer’s.\u00a0<\/span><\/p>\n

\u201cThis discovery highlights <\/span>the importance of early detection and prevention<\/b>. It also reinforces the need for clinical trials aimed at people with an increased risk of developing Alzheimer’s before the disease begins to manifest itself\u201d explains Raffaele Cacciaglia, BBRC researcher and leader of the study.
