RNA therapeutics for neurological diseases.

Introduction: Ribonucleic acid (RNA) therapeutics are a new class of drugs whose importance is highlighted by the growing number of molecules in the clinic.
Sources of Data: We focus on RNA therapeutics for neurogenetic disorders, which are broadly defined as diseases with a genetic background and with at least one clinical sign affecting the nervous system. A systematic search identified 14 RNA drugs approved by FDA and many others in development.
Areas of Agreement: The field of RNA therapeutics is changing the therapeutic scenario across many disorders.
Areas of Controversy: Despite its recent successes, RNA therapeutics encountered several hurdles and some clinical failures. Delivery to the brain represents the biggest challenge.
Growing Points: The many advantages of RNA drugs make the development of these technologies a worthwhile investment.
Areas Timely for Developing Research: Clinical failures stress the importance of implementing clinical trial design and optimizing RNA molecules to hold the promise of revolutionizing the treatment of human diseases.
