Tough scientists do not yet fully know what causes dementia, researchers have found how brain cell connections are destroyed in early stages of the disease.
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.

‘Researchers have identified a new molecular mechanism, which directly contributes to synapse loss, a discovery could eventually lead to earlier diagnosis of Alzheimer's disease and new treatments.’
"One of the first signs of Alzheimer's disease is the loss of synapses - the structures that connect neurons in the brain," says study leader, Dr Vladimir Sytnyk, of the UNSW School of Biotechnology and Biomolecular Sciences. In Alzheimer's disease, this loss of synapses occurs very early on, when people still only have mild cognitive impairment, and long before the nerve cells themselves die.
Alzheimer's disease is a widespread problem, with an estimated 5.3 million people suffering from it in United States alone.
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.

In order to arrive at an actual cure for the condition, gaining a full understanding of the processes it involves is key.

Smokers are at Risk of Alzheimer's Disease
People who smoke are at a greater risk of developing Alzheimer's disease and other forms of dementia.

"Synapses are required for all brain functions," he says, "and particularly for learning and forming memories." He adds that synapse loss occurs very early in Alzheimer's disease, long before the nerve cells die, when only mild cognitive impairment is noticeable.
Mice Breed Used In Alzheimer�s Disease Research Not That Effective
Scientists opine that recently developed mouse breeds that mimic the symptoms of Alzheimer's disease.
