Alzheimer’s disease - Causes, Symptoms, Diagnosis, Stages, Types, Prevention, Prognosis & Treatment
Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

Early detection of Alzheimer's is critical for two reasons. "First, effective treatments need to be administered well before patients show actual neurological signs," said author Robert Vince, PhD, of the Center for Drug Design at the University of Minnesota (UMN). "Second, since there are no available early detection techniques, drugs currently cannot be tested to determine if they are effective against early Alzheimer's disease. An early diagnostic tool like ours could help the development of drugs as well." Looking through the eye to see the brain is a key advantage of the new technology. "The retina of the eye is not just 'connected' to the brain -- it is part of the central nervous system," said author Swati More, PhD, also of the Center for Drug Design at UMN. While the brain and retina undergo similar changes due to Alzheimer's disease, "unlike the brain, the retina is easily accessible to us, making changes in the retina easier to observe."
"We saw changes in the retinas of Alzheimer's mice before the typical age at which neurological signs are observed," said More. "The results are close to our best-case scenario for outcomes of this project."
Risk Factors for Alzheimers Disease
Cognitively normal adults exhibiting atrophy of their temporal lobe or damage to blood vessels in the brain are more likely to develop Alzheimer’s disease.

Young Blood to Cure Decline of Aging Brain
A research showed that injections of juvenile mouse blood boosts learning and memory in older rodents, findings that hold the long-sought cure for the decline of ageing brain.

Ageing is referred to the accumulation of changes that brings a person closer to death.
