AD is characterized by the build up of amyloid plaques, neurofibrillary tangles and the loss of connections between neurons. It is the most common type of dementia especially in the elderly. The exact causes of AD are elusive at the moment but are most likely the result of genetics and other factors. Scientist have been working hard to identify individual and or groups of genes responsible for the disease.

Perhaps you’re one of these people.

The rats were given objects to play with to keep them awake. During play, electrodes were implanted in their brains to measure brain activity.
