Seizures are sudden, uncontrolled electrical disturbances in the brain, resulting in changes in behavior, feelings, and levels of consciousness. From mild symptoms that are barely noticeable to intense physical convulsions, the manifestations of seizures can vary greatly. Understanding what seizures are, their causes, and management strategies can be crucial for those who experience them or for those caring for someone who does.

What causes seizures?
Seizures can occur due to various factors, including high fever (especially in children), lack of sleep, low blood sodium (hyponatremia), certain medications, head trauma, stroke, brain tumors, drug and alcohol withdrawal, or genetic conditions. Sometimes, the cause is unknown, termed as idiopathic seizures.
What are the symptoms of a seizure?
Symptoms can range from brief periods of unresponsiveness, staring spells, rapid eye movements, to convulsions, muscle rigidity, or loss of consciousness. Some people may experience strange sensations, emotions, or behaviors just before a seizure, known as an aura.
Frequently Asked Questions
If you or someone else experiences a seizure for the first time, immediate medical help should be sought. Once stabilized, consultation with a neurologist, a doctor specializing in conditions of the brain and nervous system, would be necessary.
Investigations for seizures typically include an electroencephalogram (EEG) to measure brain electrical activity, MRI or CT scan to visualize the brain's structure, and blood tests to rule out metabolic or genetic disorders.
These tests help determine the type of seizure, its cause, the location in the brain where it begins, and guide the treatment approach. They are crucial to exclude other conditions that might mimic seizures.
Treatment of seizures primarily involves anti-seizure medications, which help control and reduce seizure frequency. In some cases, surgery, nerve stimulation therapies, or dietary therapies like the ketogenic diet may be considered.
Stay calm, remove any harmful objects from the person's vicinity, and place something soft under their head. Do not attempt to hold the person down or put anything in their mouth. After the seizure, help the person to rest on their side and stay with them until they regain consciousness.
Immediate medical attention is needed for seizures lasting longer than 5 minutes, recurrent seizures with no recovery in between, difficulty breathing after the seizure, a seizure occurring in water, or if the person is pregnant, injured, or has diabetes.
While most seizures end naturally and are not life-threatening, some seizures, such as status epilepticus (a seizure that lasts more than 5 minutes or having more than one seizure within a 5-minute period without the person returning to normal in between), can be life-threatening and need immediate medical intervention.
Yes, stress is a well-recognized trigger for seizures. Regular relaxation techniques, maintaining a balanced lifestyle, and having good emotional wellbeing can help manage stress and subsequently, seizure frequency.
Yes, the majority of people with seizures lead normal lives. Regular follow-ups with a neurologist, adherence to prescribed medications, understanding seizure triggers, and having a supportive community are key to managing life with seizures effectively.
While not all seizures can be prevented, adhering to medication schedules, getting adequate sleep, managing stress, and maintaining a balanced diet can significantly reduce seizure frequency.
Yes, not everyone who has a seizure will continue to have seizures. A one-time seizure could be triggered by a high fever, drug withdrawal, or severe metabolic disturbance, and may not recur.
Epilepsy is a central nervous system disorder in which brain activity becomes abnormal, leading to repeated seizures or periods of unusual behavior, sensations, and sometimes loss of awareness.
If your seizures are well-controlled, your doctor may recommend annual visits. However, you should seek immediate medical care if your seizures become more frequent or severe, or if you experience new symptoms.
