Blood transfusions could cause dementia

Scientists have linked Alzheimer’s disease with blood transfusions. They found a protein that could be behind the development of this memory robbing disease transmitted by the now banned procedure.

Now prohibited species blood transfusions, which is widely used in different countries until the 1980s, years could pass people with Alzheimer’s disease – the most common kind of dementia. In the period from the late 1950s until 1985, with a significant deficit growth of the hormone extracted from corpses in order to stimulate growth. However, in the early 1980s, an outbreak of the disease Creutzfeldt-Jakob disease – a fatal neurological disorder, which was associated with those transfusions. As a result, in 1985 the method was officially banned, and she was replaced by synthetic hormones. Since then, the researchers carefully watched the people who passed through these blood transfusions, to evaluate and other side effects.

And now among these side effects appeared Alzheimer’s. Scientists have obtained new evidence that the transfusion of cadaveric blood leads to the aggregation of amyloid proteins in the brains of patients. A similar effect was achieved in experiments using laboratory mice. After blood transfusions in rodents signs of the incurable form of dementia emerged in the course of the year. The authors of the study are scientists from University College London.

Magicforum reminds us that Alzheimer’s disease today, there are about 1 million Russians. It arises in the moment when the connection between the billions of nerve cells in the brain are lost because of accumulations of amyloid and Tau proteins that form abnormal plaques and tangles. Over time, different brain areas are reduced, and controls memory area of the brain suffers first. The disease is incurable, and all treatment methods focused on control of her symptoms. (READ MORE)
