A new clue to the cause of Alzheimer’s disease has been discovered by the researchers. A sticky protein known as beta-amyloid, clutter the brains of people that have memory-robbing form of dementia. But this is still a riddle whether this sticky protein is a side effect or a cause of the disease. Tangles of a protein known as tau are also involved in this procedure, some scientists considering it a cause.
Injecting rats with a specific kind of beta-amyloid, the researchers caused Alzheimer’s symptoms in them. The researchers noted that other kinds of beta-amyloid when injected to the rats, it didn’t cause illness in them. It shows that some people have beta-amyloid plaque in their brains but don’t have symptoms of the disease.
These findings were reported in online issue of the journal …Click here to read more
