The United States faces a mental health epidemic. Nearly one in five American adults suffers from a form of mental illness. Suicide rates are at an all-time high, 115 people die daily from opioid abuse, and one in eight Americans over 12 years' old take an antidepressant every day. The economic burden of depression alone is estimated to be at least $210 billion annually, with more than half of that cost coming from increased absenteeism and reduced productivity in the workplace. In a crisis that has become progressively dire over the past decade, digital solutions -- many with artificial intelligence (AI) at their core -- offer hope for reversing the decline in our mental wellness.
