Debilitating Symptom Complexes Attributed to Ticks

DSCATT is currently approached as a medically unexplained syndrome. DSCATT is an Australian term for a chronic, multifaceted illness attributed by affected people to tick bites despite the absence of endemic Lyme disease in Australia. DSCATT lacks established diagnostic biomarkers, agreed symptom criteria and pathophysiological mechanisms. The term DSCATT was adopted after a 2016 Australian Senate inquiry to acknowledge severe symptoms while reducing stigma and controversy around terms such as chronic Lyme disease. No Lyme-like illness has been definitively attributed to Lyme disease acquired in Australia.
