ABSTRACT
Explanation: Lyme disease is caused by spirochaete Borrelia burgdorferi that is transmitted by Ixodes ticks. It has three stages: stage 1, rash; stage 2, early neurological signs, including lymphocytic meningitis, radicular pains, facial palsy, transverse myelitis and cranial and peripheral neuropathies; stage 3 (occurs 7 years after the initial diagnosis), late neurological signs, including Bell’s palsy, dementia, encephalomyelitis, hemianopsia, hemiplegia, radiculo-neuropathy and seizures. Other typical symptoms of chronic Lyme encephalopathy include poor memory and concentration, fatigue, daytime hypersomnolence, irritability and depression.
