Alzheimer’s Disease

Early diagnosis of Alzheimer’s can lead to measures that help preserve cognitive function, prolong independent living, and improve quality of life, symptom management and the efficacy of disease-modifying therapies.

Signs and symptoms of Alzheimer's, such as cognitive decline, manifest years after disease onset. Mild cognitive impairment (MCI) is a condition that may be the first outward sign of Alzheimer’s in its earliest stages. 
Alzheimer’s disease affects memory, behavior, problem-solving and daily activities. It’s a medical condition – not part of normal aging – and one of the biggest public health challenges of our time. View the table below to compare normal signs of aging and Alzheimer’s.

Our solutions


Many people with Alzheimer’s are not aware they have it or have not been diagnosed; although, surveys by the Alzheimer’s Association found that 85% of people would want to know early if they had the disease.1

An early and accurate diagnosis allows those facing Alzheimer's, under the guidance of their physician, an opportunity to take steps to preserve cognitive function, make better care plans, and get involved in clinical research that may lead to new treatments. Learn more here.
