How Does Lyme Disease Affect the Brain?
Lyme disease is a bacterial infection that you can catch if you’ve been bitten by an infected deer tick. The first symptoms of Lyme disease, which include a target-shaped rash, fatigue, swollen lymph nodes, muscle aches, and headache, can appear within a few days or weeks. Your doctor can promptly recognize and diagnose Lyme disease and treat it with antibiotics. But when treatment is delayed, the infection can spread to other areas, including the nerves, liver, and eyes. The infection can also spread to the central nervous system –- the brain and spinal cord –- and cause the problems listed below.
Common Cognitive Effects
Lyme disease can cause encephalopathy, also called brain fog, which is a general term used for a condition that affects the way your brain functions. Its effects include:
- Memory loss
- Difficulty focusing
- Difficulty forming words or thoughts
- Personality changes
- Symptoms similar to dementia and Alzheimer’s
- Disorganization and getting lost
Lyme Disease and Meningitis
Lyme disease can cause meningitis and encephalitis. Meningitis is a swelling of the lining of the brain and spinal cord. Encephalitis is a swelling of the brain itself. The symptoms of both are similar and include:
- Stiff neck
- Sensitivity to light
- Memory loss
- Impaired reasoning abilities
Both conditions are treated with intravenous (IV) antibiotics.
Lyme disease can also cause mental or psychiatric problems, including:
- Sleep disorders
Although rare, more severe cases of Lyme disease may have some connection to:
- Obsessive-compulsive disorder
