What are absence seizures?
An absence seizure causes you to blank out or stare into space for a few seconds. They can also be called petit mal seizures. Absence seizures are most common in children and typically don’t cause any long-term problems. These types of seizures are often set off by a period of hyperventilation.
Absence seizures usually occur in children between ages 4 to 14. A child may have 10, 50, or even 100 absence seizures in a given day and they may go unnoticed. Most children who have typical absence seizures are otherwise normal. However, absence seizures can get in the way of learning and affect concentration at school. This is why prompt treatment is important.
Absence seizures are a type of epilepsy, a condition that causes seizures. Seizures are caused by abnormal brain activity. These mixed messages confuse your brain and cause a seizure.
Not everyone who has a seizure has epilepsy. Usually, a diagnosis of epilepsy can be made after two or more seizures.
Absence seizures often occur along with other types of seizures that cause muscle jerking, twitching, and shaking. Absence seizures may be confused with other types of seizures. Doctors will pay close attention to your symptoms in order to make the right diagnosis. This is very important for effective and safe treatment of your seizures.
It’s uncommon for absence seizures to continue into adulthood, but it’s possible to have an absence seizure at any age.
What causes absence seizures?
Like other kinds of seizures, absence seizures are caused by abnormal activity in a person’s brain. Doctors often don’t know why this happens. Most absence seizures are less than 15 seconds long. It’s rare for an absence seizure to last longer than 15 seconds. They can happen suddenly without any warning signs.
What are the symptoms of absence seizures?
The easiest way to spot an absence seizure is to look for a blank stare that lasts for a few seconds. People in the midst of having an absence seizure don’t speak, listen, or appear to understand. An absence seizure doesn’t typically cause you to fall down. You could be in the middle of making dinner, walking across the room, or typing an e-mail when you have the seizure. Then suddenly you snap out of it and continue as you were before the seizure.
These are other possible symptoms of an absence seizure:
Being very still
Smacking the lips or making a chewing motion with the mouth
Fluttering the eyelids
Stopping activity (suddenly not talking or moving)
Suddenly returning to activity when the seizure ends
If you experience jerking motions, it may be a sign of another type of seizure taking place along with the absence seizure.
How are absence seizures diagnosed?
You may have absence seizures repeatedly for years before heading to the doctor for a diagnosis. You may have “staring spells” without thinking of them as a medical problem or a seizure.
An EEG is a test most often used to diagnose absence seizures. This test records the brain’s electrical activity and spots any abnormalities that could indicate an absence seizure.
These tests also can help to diagnose absence seizures or rule out other conditions:
Tests of the kidneys and liver
CT or MRI scans
Spinal tap to test the cerebrospinal fluid
How are absence seizures treated?
Absence seizures can affect your ability to perform at work or school, so it’s a good idea to see your healthcare provider about treatment.
Absence seizures can be treated with a number of different antiseizure medicines. The type of medicine that your healthcare provider recommends you take will also depend on what other seizure disorder you may have. If you have more than one type of seizure disorder, you may need to take multiple medicines.
Can absence seizures be prevented?
Taking your medicines exactly as your doctor prescribed is one of the best ways to manage absence seizures. But you can also make some changes in your life to help prevent absence seizures from happening. These include:
Get plenty of sleep each night.
Find ways to manage your stress.
Eat a healthy diet.
Living with absence seizures
Most people with epilepsy live full and active lives with medicine and other lifestyle changes. But it can be challenging at times to manage large and small life events when you have epilepsy. Depending on your age and the severity and type of epilepsy, you may need support with the following:
Behavioral and emotional issues. It is important to get enough sleep and manage stress when you have epilepsy. Stress and lack of sleep can trigger seizures. If you have trouble sleeping, talk with your healthcare provider about how to make sure you get enough sleep. Learn coping techniques that will help you manage stress and anxiety.
Employment. With proper treatment, people with epilepsy can do just about any job safely and effectively. But, certain jobs in which there is a high risk to public safety may not be an option. Epilepsy is covered under the Americans with Disabilities Act. This law prohibits discrimination against people with epilepsy and other disabilities.
Coping with discrimination and stigma. Children and adults with epilepsy may face discrimination and struggle to overcome the stigma associated with this neurological condition. Help educate family, friends, co-workers, and classmates on your condition. Let them know what to expect and how to help during a seizure.
Education. Children with epilepsy may be entitled to special services under the Individuals with Disabilities Education Act (IDEA). Working closely with the child’s teacher and school nurse will help improve management of epilepsy at school. It’s important for parents of children with epilepsy to balance safety and fun. Allow your child to have some age-appropriate independence and participate in sports and other activities at school, when possible.
Driving. Each state has different driving laws for people with epilepsy. Licensing may depend on how severe seizures are and how well they are controlled. Consider public transportation where it is available. If you continue to have absence seizures, it may not be safe for you to drive.
Support and online resources. You may feel alone in dealing with day-to-day life with epilepsy, but be assured that many people have epilepsy. You can find local support groups through your healthcare provider or local hospital. Many online resources give tools and tips for managing this condition. Online social media support groups bring together people from all over the world who are managing their epilepsy. These groups provide support and encouragement.
If you have trouble managing your absence seizures, you may want to work more closely with your healthcare provider to find a better way to treat them.

A stroke, also known as cerebrovascular accident (CVA), cerebrovascular insult(CVI), or brain attack, can occur when a part of the brain is deprived of blood flow. When brain cells are deprived of oxygen they begin to die, due to which the functions controlled by that part of the brain also stops, which results in different types of disabilities among stroke survivors.
There are two types of strokes
- Ischemic stroke
The first is caused when a brain aneurysm or a weak blood vessel bursts. Most of the time, this type of stroke leads to death. The second one happens when a clot blocks the flow of blood to the brain. Patients suffering from stroke suffer from various side-effects, the most common ones being paralysis or loss of feeling in a certain part of the body, problem in understanding or talking and loss of vision on one side. The side-effects start showing up immediately after a person has had a stroke.
In certain conditions, blood flow to a certain part of the brain stops for only some time and hence the body suffers stroke-like symptoms which only last a couple of hours before disappearing. This is known as a transient ischemic attack (TIA). Unfortunately, the effects of a stroke can be debilitating and also permanent. Hence, it's important to know the symptoms of a stroke and rush the patient to a doctor as soon as possible. Sometimes early treatment can save a lot of damage.
The primary symptoms of stroke are as follows:
- Confusion and problems while talking and comprehension
- Headache along with alteration of consciousness or vomiting
- Numbness of the face, arms or legs, especially on one side of the body
- Issue with seeing, through one or both eyes
- Inability to walk with stability, including disrupted coordination
- Problems with the bladder and bowel control
- Acute depression
- Body temperature fluctuates, and pain worsens with movement
- Paralysis on one side of the body along with fatigue
- Problem in expressing or controlling emotions
Diagnosis of stroke
Several tests are carried out to determine the type of stroke, such as
- Physical examination, which involves observing the patient's overall condition.
- Blood tests
- CT scans
- MRI scans
- Cerebral angiogram
Stroke is a fatal brain disease and can cause permanent damage to your system so its best to check with doctor to know how you can prevent it.
