According to a new study published in Alzheimer's Research and Therapy, reduced to a test vaccine two types of toxic prototypes that were suspected as an Alzheimer's cause, with no adverse effects such as brain output.
The ten-year study was carried out by Peter O Donnell Jr. Brain Institute at the Texas University of Southwestern.
"If the start of the illness was delayed even five years, it would be very great for the patient and their families," said Dr. Doris Lambracht-Washington, the author of the survey. "The number of cases of dementia could fall down a half."
An earlier promising vaccine caused "bad bad brain" in some patients.
A vaccine that is delivered with a skin; Use a protection response that reduces damaging tau and beta-amyloids.
"This study is about ten years of research that has recently been shown that this vaccine can effectively and safely focus on animal models than we are thinking about Alzheimer's disease, "said Dr Roger Rosenberg, Director of the Alzheimer's Disease Center at UT Southwest. "I believe we're getting close to testing this medicine in humans."
Until now, it has been safely proven in three mammals and may allow periodic to clinical trials.
"A vaccine is a short list of antibody-resistant drivers aimed at protecting against the two types of protons that kill brain cells while they are" spread in fatty plates and crack on Alzheimer's disease patients, "said a press release from UT Southwestern.
Alzheimer's continues to decrease the brain in about 5.7 million American patients. It is expected to double that number by 2050, according to the Center for Control and Disease Diseases (CDC).
At present, there is no effective cure for Alzheimer's.
The new study says that its vaccine can be more effective in patients with high levels of "tau and amyloid stored in the brain," but before the patient is completely restored to Alzheimer's.
"The time you wait, the more likely it will be," said Dr Rosenberg. "Once these records and stones are created, it may be too late."
