Alzheimer’s is a terminal and degenerative disease for which there is known no cure. In its common form, it affects people over 65 years old. Still, an early-onset form exists. Each individual experiences the symptoms of Alzheimer’s in unique ways. Generally, the symptoms are those reported when memory loss becomes apparent.

The duration of the disease varies and could develop for an indeterminate time before becoming fully apparent. Sometimes, it could not be diagnosed for years. Life with Alzheimer’s lasts between 5 to 20 years. The most commonly symptom is memory loss, as well as difficulty to remember recently learned facts.

Researchers have recently got into people’s brains to discover the ebb and flow of the substance that has the most important role in Alzheimer’s disease. Still, doctors didn’t search inside people who suffer from Alzheimer’s, but inside the people with severe brain injuries.

The serious brain injuries are the ones that cause dementia sometime in life.

The substance that causes Alzheimer’s is beta-amyloid, a very harmful protein inside the brain. The level of this substance is the one that shows how badly damaged might be the brain or, on the other hand, how much of it it’s cured.

Dr. David Brody, a neurologist at Washington University in St. Louis said that "Our study is just the beginning, amyloid-beta measurements in the brain may turn out to be a good indicator of how well the cells are communicating with each other.”

The beta-amyloid is the substance that mingles the hallmark plagues inside the people with Alzheimer’s. Soluble forms can be found in the fluid that washes the brain.
