Today, 5 million Americans suffer from Alzheimer's disease; 1 million from Parkinson's; 400,000 from multiple sclerosis (MS); 30,000 from amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease), and 30,000 from Huntington's disease. Because neurodegenerative diseases strike primarily in mid- to late-life, the incidence is expected to soar as the population ages. (By 2030, as many as 1 in 5 Americans will be over the age of 65.) If left unchecked 30 years from now, more than 12 million Americans will suffer from neurodegenerative diseases. Finding treatments and cures for neurodegenerative diseases is a goal of increasing urgency.
In recent years, scientists of the Harvard NeuroDiscovery Center and many others have made great strides in understanding the underlying causes of neurodegenerative diseases. As we uncover more details of these diseases, we are confident that in time we will be able to treat and prevent them. But as for most major endeavors, the greater the resources we bring to bear, the faster the progress toward our goal. If — as a community — we want to avoid the looming and dramatic impact of these diseases on our increasingly elderly population, we must all redouble our efforts, now.
