❓ Frequently Asked Questions
Q: What exactly happens in the brain during a seizure?
A: During a seizure, there’s an abnormal, excessive, and synchronous neuronal activity in the brain. This can disrupt normal brain function, leading to changes in awareness, behavior, and motor control.
Q: What is the difference between a seizure and epilepsy?
A: A seizure is a single event of abnormal brain activity, while epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures.
Q: What are the main causes of epilepsy?
A: Epilepsy can be caused by a variety of factors including genetic predisposition, brain injury, stroke, infections, and developmental abnormalities. In many cases, the exact cause remains unknown.
Q: How is epilepsy diagnosed?
A: Epilepsy is usually diagnosed through a combination of medical history, neurological examination, and diagnostic tests such as electroencephalogram (EEG) to measure brain activity and imaging scans like MRI to identify structural abnormalities.
Q: Can epilepsy be cured?
A: While there is currently no cure for epilepsy, many people with epilepsy can effectively manage their seizures with medication, surgery, or other therapies. Some children with certain types of epilepsy may outgrow the condition.
Q: What are some common seizure triggers?
A: Common seizure triggers can include sleep deprivation, stress, alcohol or drug use, flashing lights, and hormonal changes. Identifying and avoiding triggers can help reduce the frequency of seizures.
