Since the earliest descriptions of Alzheimer's disease (AD), many theories have been advanced as to its cause. These include: (1) exacerbation of aging, (2) degeneration of anatomical pathways, including the cholinergic and cortico-cortical pathways, (3) an environmental factor such as exposure...
All three of these genes cause early-onset Alzheimer's disease, which means symptoms typically start when people are in their early 40s to mid-50s. A second group of genes is called risk genes. Although they can contribute to the development of Alzheimer's, having these genes doesn't mean...
But before you panic, there are some steps you can take to prevent this condition — and learn more about how you might be at risk. What is early-onset Alzheimer’s disease? Alzheimer’s disease is a neurologic disorder that causes the brain to slowly shrink and cells to die. Though ...
A letter to the editor is presented in response to the review of the book "The Alzheimer Conundrum: Entanglements of Dementia and Aging," in the May 22, 2014 issue along with a response by Jerome Groopman.LockMarjorieMargaretMarjorie
What’s the Difference Between Alzheimer’s and Dementia? Dementiarefers to a group of brain disorders that make it hard to remember, think clearly, make decisions, or even control your emotions. Alzheimer’s disease is one of those disorders, but there are many types and causes of dementia....
Alzheimer’s results in a major loss of brain cells (neurons) and their connections (synapses), starting in the areas of the brain that control memory. As damage spreads throughout the brain, more cognitive and physical abilities are affected. This causes the brain to physically shrink. ...
Alzheimer's disease is a neurodegenerative disorder characterized by gradual memory loss and declining cognitive function. Find out the causes and symptoms of Alzheimer's disease and the diagnosis and treatment for this neurological condition.

Researchers continue looking in to the risk factors - and potential treatments - of Alzheimer's disease.
The study, published today in the Journal of Neuroscience, opens up the possibility that two of the main suspects in Alzheimer's development -- amyloid plaques and tangles of tau proteins in the brain -- are not acting alone. "You're finding a molecular pathway that we hadn't thought of...
