Clinical Information
- Seizures are sudden bursts of electrical activity that can cause changes in muscle tone, movement, awareness, consciousness, or sensations.
- There are two main types of seizures: focal/partial and generalized-onset. A seizure fall under one or the other category depending on the location, severity, or cause.
- Someone is having a seizure when they lose consciousness, wake up confused, have muscle spasms, froth at the mouth, clench teeth, bite their tongue, lose bladder or bowel function, make unusual noises, and fall.
- Some causes may be a brain infection/injury, substance/alcohol use/withdrawal, epilepsy, fever, head trauma, stroke, brain tumor, low blood glucose levels, and electric shock. It’s also possible that having seizures is genetic.
- Short-term effects on patients are injury. Meanwhile, long-term effects, especially prolonged, are mental health problems, coma, or premature death.
- To diagnose a seizure disorder, a practitioner may ask for one’s medical history, including symptoms before the seizure, and other tests such as blood tests, spinal tap, toxicology, EEG, CT scans, and MRI scans.
- Treatments include a change in diet and medication. However, if those two don’t worry, practitioners may recommend brain surgery and nerve stimulation.
