Lyme Disease | Pathophysiology, Signs, and Treatment

The video provides an overview of Lyme disease, caused by Borrelia bacteria transmitted by ticks. It explains the transmission cycle involving rodents and deer, and details the three stages of the disease: early localized, early disseminated, and late persistent. Symptoms include erythema migrans, neurological and cardiac issues, and arthritis. A mnemonic 'bake a Key Lime Pie' helps remember key symptoms. Diagnosis involves clinical presentation and serology, while treatment varies by stage, using antibiotics like doxycycline. Prevention focuses on avoiding tick bites.
