What are seizures?
Seizures are changes within the brain’s electrical activity. These changes can cause dramatic, noticeable symptoms, or in other cases no symptoms in the least.
The symptoms of a severe seizure include violent shaking and a loss of control. However, mild seizures also can be a symbol of a big medical problem, so recognizing them is vital.
Because some seizures can cause injury or be a symbol of an underlying medical condition, it’s important to hunt treatment if you experience them.
What are the kinds of seizures?
The International League Against Epilepsy (ILAE) introduced updated classifications in 2017 that better describe the various differing types of seizures. The 2 major types are now called focal onset seizures and generalized onset seizures.
Focal onset seizures
Focal onset seizures wont to be mentioned as partial onset seizures. They occur in one area of the brain.
If you recognize that you’re having a seizure, it’s called a focal aware seizure. If you’re unaware when the seizure occurs, it’s referred to as a focal impaired awareness seizure.
Generalized onset seizures
These seizures start in each side of the brain simultaneously. Among the more common sorts of generalized onset seizures are tonic-clonic, absence, and atonic.
Ø Tonic-clonic: These also are referred to as generalized seizure seizures. “Tonic” refers to muscle stiffening. “Clonic” refers to the jerky arm and leg movements during the convulsions. you'll likely lose consciousness during these seizures which will last for a couple of minutes.
Ø Absence: Also called petit-mal seizures, these last for less than a couple of seconds. they will cause you to blink repeatedly or stare into space. people may mistakenly think you’re daydreaming.
Ø Atonic: During these seizures, also referred to as drop attacks, your muscles suddenly go limp. Your head may nod or your entire body could fall to the bottom . Atonic seizures are brief, lasting about 15 seconds.
Unknown onset seizures
Sometimes nobody sees the start of a seizure. For instance, someone may awaken within the middle of the night and observe their partner having a seizure. These are called unknown onset seizures. They’re unclassified due to insufficient information about how they started.
What are the symptoms of a seizure?
You can experience both focal and generalized seizures at an equivalent time, or one can happen before the opposite. The symptoms can last anywhere from a couple of seconds to fifteen minutes per episode.
Sometimes, symptoms occur before the seizure takes place. These can include:
Ø a sudden feeling of fear or anxiousness
Ø a feeling of being sick to your stomach
Ø dizziness
Ø a change in vision
Ø a jerky movement of the arms and legs which will cause you to drop things
Ø an out of body sensation
Ø a headache
Symptoms that indicate a seizure is ongoing include:
Ø losing consciousness, followed by confusion
Ø having uncontrollable muscle spasms
Ø drooling or frothing at the mouth
Ø falling
Ø clenching your teeth
Ø biting your tongue
Ø having sudden, rapid eye movements
Ø losing control of bladder or bowel function
Ø having sudden mood changes
What causes seizures?
Seizures can stem from variety of health conditions. Anything that affects the body also may disturb the brain and cause a seizure. Some examples include:
Ø alcohol withdrawal
Ø a brain infection
Ø a brain injury during childbirth
Ø a brain defect present at birth
Ø choking
Ø drug abuse
Ø drug withdrawal
Ø an electrolyte imbalance
Ø electric shock
Ø epilepsy
Ø a fever
Ø head trauma
Ø kidney or liver failure
Ø a stroke
Seizures can run in families. Tell your doctor if you or anyone in your family features a history of seizures. In some instances, especially with young children, the explanation for the seizure could also be unknown.
How are you able to prevent seizures?
In many instances, a seizure isn’t preventable. However, maintaining a healthy lifestyle can offer you the simplest chance at reducing your risk. You’ll do the following:
Ø Eat a healthy diet and stay well hydrated.
Ø Exercise regularly.
Ø Engage in stress-reducing techniques.
Ø Avoid taking illegal drugs.
