Hi Marlene. When there is volume loss in the brain, for whatever reason, that extra space is filled with CSF. As long as the CSF is flowing normally, there usually are no symptoms of increased pressure such as chronic headache, balance issues, blurred vision, drop in alertness, etc. It is only when the flow of CSF is impaired, and pressure builds up, that such symptoms occur. This can be tested by doing a lumbar puncture (spinal tap). Otherwise, you have to look for other explanations.
I can't take a call right now, but I can continue to work with you. Do you have additional questions?
Are you still there, Marlene?
If you are concerned about Lyme disease, this can be tested and treated quite easily.
Ask your doctor to run the blood test for Lyme. If positive, you may need a course of doxycycline or cefuroxime.
You probably do not have Lyme based on this. Some doctors in this country will treat anyway, as the antibiotic is safe and well tolerated by most. That said, if your headaches have worsened you should see a neurologist. He or she can do a lumbar puncture to test the pressure of your CSF and also test for evidence of Lyme or some other central nervous system infection.
