Neurology is the medical field that focuses on the nervous system, which includes the brain, spinal cord, and nerves. Neurologists treat a variety of conditions, from headaches and sleep problems to more complex issues like epilepsy. Understanding how neurologists approach epilepsy can give you a better idea of how they diagnose and treat this condition. Here’s more information about their role:
Blood Tests
When you see a neurologist for seizures, one of the initial steps may involve blood tests. A sample of your blood may be drawn and sent to a laboratory for analysis. This process helps your doctor gather more information about your overall health. The results from these tests may reveal signs of infections or genetic conditions that could be related to the seizures.
Blood tests also allow doctors to check for other health problems that might mimic epilepsy. These may contribute to seizure activity. By examining different components in your blood, your neurologist may rule out certain possibilities and get a better understanding of your physical state.
EEG Scans and MRIs
To look directly at the brain’s activity and structure, neurologists may use specialized imaging and monitoring tools. An electroencephalogram (EEG) is a common test used to detect electrical activity in your brain. During an EEG, small sensors are attached to your scalp.
These sensors record the electrical signals your brain cells use to communicate with each other. The test helps identify unusual patterns that might point to epilepsy. You might have an EEG while you are awake or asleep to capture a potential seizure event.
Another powerful diagnostic tool in neurology is magnetic resonance imaging (MRI). An MRI scan uses a strong magnetic field and radio waves to create detailed images of your brain. This allows your neurologist to see the brain’s structure clearly. They can look for tumors, scarring, or developmental issues that may be the source of the seizures.
Vagus Nerve Stimulation
For some individuals, when medications do not provide sufficient seizure control, they can choose from other treatment options. One such option is vagus nerve stimulation (VNS). This treatment involves surgically placing a device, similar to a heart pacemaker, under the skin in the chest area. A wire connects this device to the vagus nerve in your neck.
The device is programmed to send mild, regular electrical pulses to the brain through the vagus nerve. These pulses aim to help stabilize irregular electrical activity that can cause seizures. Your neurologist can adjust the settings on the VNS device over time to find the most effective configuration. Patients also receive a magnet they can use to deliver an extra pulse if they sense a seizure coming on.
Surgical Procedures
In specific cases, brain surgery may be an option for treating epilepsy. This approach is generally explored when seizures are difficult to control with other methods and when they originate from a single, identifiable area of the brain. Before any procedure, you will undergo an extensive evaluation to determine if surgery is a suitable path for you. This evaluation typically includes:
- Detailed brain imaging
- Prolonged EEG monitoring to pinpoint the seizure focus
Other surgical techniques are also available, such as procedures that interrupt the nerve pathways that allow seizures to spread.
