Tulane University researchers found the bacterium that causes Lyme disease in the brain tissue of a woman who had long suffered neurocognitive impairment after her diagnosis and treatment for the tick-borne disease. The presence of the corkscrew-shaped Borrelia burgdorferi spirochetes in the former Lyme disease patient’s brain and spinal cord were evidence of a persistent infection.
The findings were published in Frontiers in Neurology.
The 69-year-old woman, who experienced progressively debilitating neurological symptoms throughout her illness, decided to donate her brain to Columbia University for the study of the disease as her condition worsened. While she had first experienced the classic symptoms of Lyme disease 15 years prior and was treated accordingly after her diagnosis, she experienced continual neurological decline including a severe movement disorder and personality changes, and eventually succumbed to Lewy body dementia. Lewy body dementia is associated with abnormal protein deposits in the nerve cells of the brain which can cause impairment in thinking, movement and mood, leading to a severe form of dementia.
This is the first time researchers have identified a possible correlation between Lyme disease infection and Lewy body dementia.
