They made it difficult to sleep which made things progressively worse. I checked myself into the hospital. They adjusted my medications, gave group therapy, and monitored me. I believe I slept for 12 hours each night 3 days in a row. What a relief! The hallucinations finally subsided.

58. • Bill Gates: …Alzheimer’s starts damaging the brain more than a decade before symptoms start showing. That’s probably when we need to start treating people to have the best shot at an effective drug. • 400 trial failures due to lack of early detection Early Detection is Key to Solving Brain Diseases

59. • Extremely high quality data • So sensitive, it can pick up very slight changes • So statistically powerful that diagnostic capability can be proven • Basically, 0% false negatives or positives, AUC=1.0 • This means much higher bar than we are used to – r2 of 0.9 or better • Generates lots of variables, so fingerprints for each disease can be generated Early Detection: Requirements

60. •Can be deployed widely • Easy on the person • Runs in background • No additional hardware • Low cost • Easy to implement Early Detection: Requirements

61. •Can be done with significant risk factors • Huntington’s (HD) 100% • Alzheimer’s (AD) APOE4 • 1 – 20% of population – 35-40% risk • 2 – 2% of population – 100% risk Challenge #1: Proving Diagnostic Capability
