ALEX McMEEKING, MD: It's commonly also known as a spinal tap. What it involves is -- a way of diagnosing if somebody has Lyme disease in their central nervous is to take out some spinal fluid from the base of their spine. It's actually quite a safe procedure. The only thing it can cause is a bad headache afterwards. They take out the spinal fluid, they look under the microscope for white blood cells, they measure for elevations in chemicals such as protein, which is often increased, and you can also actually measure through something called a polymerase chain reaction, which is a newer test for the actual bacteria that causes Lyme disease.
DAVID FOLK THOMAS: So is the bottom line with Lyme disease that you need to catch it as early as possible so you don't develop those later symptoms?
ALEX McMEEKING, MD: That's the thing. The earlier you can make a diagnosis and treat somebody, the less likely you're going to get chronic manifestations of Lyme disease. Absolutely.
DAVID FOLK THOMAS: All right, that's all the time we have. We've been discussing treating Lyme disease, and of course -- I guess I'm not saying anything new -- the best treatment would be try not to get it in the first place. But if you're aren't lucky enough, we hope you've learned something here today.
My name's David Folk Thomas. We'll see you next time.
