A Billion Lives in the Balance

It is estimated that CNS disorders affect as many as one billion people worldwide. Alzheimer’s disease, Huntington’s disease, ADHD, epilepsy, depression, and various pain disorders can not only affect a patient’s health, well-being and quality of life, but also the lives of those around them. The impact on patients, caregivers, families, and communities can be devastating.
