Remarkably honest, brutally heroic and darkly humorous memoir following a devastating diagnosis of early onset Parkinson's disease. Twitch is a frank and funny memoir about picking up the pieces when personal tragedy hits. In 2021, Irish Examiner columnist, stylist, author and podcaster Annmarie O'Connor was diagnosed with early-onset Parkinson's disease, an incurable neurodegenerative condition broadly affecting movement and mental health.

Though she is no longer working as a stylist as part of her career due to Parkinson's complications, Twitch outlines her journey from a life-altering diagnosis to becoming an activist and agent of change.
