Neurodiagnostics
The following neurology services are available at San Antonio Regional Hospital's Neurodiagnostic Lab:
- Electroencephalogram (EEG)- Monitors electrical brain wave activity
- Intraoperative monitoring
You may contact our Neurodiagnostic lab weekdays, from 7:30 am to 4 pm, at 909.920.4860.
EEG Monitoring
The Neurodiagnostic Department at San Antonio Regional Hospital is committed to clinical excellence, superlative technical performance, and innovation in diagnosis and therapy. Among special services provided by our Neurodiagnostic Department is the diagnosis
and treatment of epilepsy—a common disorder.
Seizures that are unprovoked and recurrent are considered epileptic and are classified as either generalized seizures or partial seizures. Generalized seizures begin as widespread neuronal excitation in both hemispheres of the cortex, whereas partial
seizures begin focally in a limited area of the cortex.
Evaluation helps determine the type of seizures (epileptic versus nonepileptic) and their cause, since various seizure types respond best to specific treatments.
Diagnostic tests for epilepsy that are available at San Antonio include blood tests, EEG, and advanced imaging techniques such as MRI and MR Spectroscopy. Comprehensive, pre-surgical diagnostic procedures include EEG monitoring, neuropsychological
testing as a predictor of possible cognitive loss following surgery, the WADA (intracarotid sodium amobarbital procedure) test to help determine the risk of post-operative memory and language deficits, and intracranial EEG.
Pharmacotherapy is a key component of epilepsy management. Factors to consider include seizure type and epilepsy type, side effects, ease of use of the Anti-Epileptic Drugs (AED), and cost. The goal is to achieve the best balance among efficacy, tolerability
and safety. Because patients may take AEDs for many years, long-term efficacy and tolerability should be considered.
When medication is not effective in controlling seizures, surgical correction of epilepsy may be considered. Surgical options include resection of the epileptogenic focus. At San Antonio, we implant Vagus Nerve Stimulators, which are devices that produce electrical signals along the vagus nerve to help prevent seizures.
Testing to determine the source of the seizure and location in the brain is crucial in determining whether it is in fact epilepsy, and what the most effective treatment plan would be for the patient. San Antonio Regional Hospital's Neurodiagnostic Department
can help.
