One of the many symptoms of Lyme Disease can be seizures, below is a link into a conference in which the first one Pat Smith talks about her daughter who suffered with Temporal Lobe Epilepsy as part of her complex Lyme disease symptoms.
Seizures page 33
"Along with or months after erythema migrans, cranial neuropathy or Lyme arthritis, the five children developed behavioral changes, forgetfulness, declining school performance, headache or fatigue and in two cases a partial complex seizure disorder." (1)
"Coma has been reported in at least five patients, and seizures of a variety of types, in at least nine: Partial complex, focal motor, and both primary and secondary generalized convulsive seizures have all been reported." (4)
"We describe a child whose first manifestation of Lyme disease was an acute, focal meningoencephalitis with signs and symptoms such as fever, headache, slurred speech, hemiparesis, seizure, and CSF pleocytosis. " (5)
"Another was a 40-year-old man presenting with epileptic seizures and MRI-detected multifocal lesions, which disappeared after repeated courses of antibiotics."
Details of presentations to the review panel of the IDSA Lyme Disease guidelines can be found at http://www.ilads.org/
These presentations leave you in no doubt of the fact that current blood tests for Lyme Disease can miss up cases and that for some people long term antibiotics are required.
With the controversy over the current guidelines how many people suffering seizures are ever properly assessed to see if Lyme Disease could be the cause.
