THE NEW AGE OF
ALZHEIMER’S DISEASE

A new age for Alzheimer’s disease (AD) stands before us, with
unprecedented possibilities for patients, care partners, and health
care professionals. Paired with our long-term vision and commitment
to our human health care (hhc) mission, we use deep human biology
and genetic evidence with the goal of providing the right
intervention, for the right person, at the right time.

WHAT IS ALZHEIMER’S DISEASE?

Alzheimer’s disease (AD) is progressive. Even in the early stages, AD can begin to interfere with daily life.

AD is linked to the build-up of amyloid protein in the brain, which over time can damage brain cells and clump together into harmful amyloid brain plaques.

Various mechanisms have been proposed over the years to describe the pathogenic events that lead to the development of AD, all of which suggest that the presence of Aβ and tau, synaptic failure, and neuronal dysfunction are common features of AD and play a pivotal role in cognitive dysfunction.

WHAT DOES ALZHEIMER’S LOOK LIKE?

There are many complexities in the AD landscape: risk factors, early symptoms,
causes, diagnoses, and stages. Early detection is one of the keys to the right person, receiving the right medication, at the right time.

THE KEY TO OUR PROGRESS IN TWO WORDS?
RESEARCH EXCELLENCE.
