However, experiencing a prolonged seizure can cause injury. These types of seizures are called status epilepticus.
Permanent neurological damage can happen after about 30 minutes of status epilepticus due to prolonged abnormal electrical activity in the affected area of the brain.
Do seizures cause permanent damage?
Usually, a seizure does not cause any lasting damage to the brain
. However, having many seizures, or having seizures that are particularly severe, may cause a person to become more forgetful or find it difficult to concentrate. People with epilepsy have an increased risk of developing depression.
How long does it take your brain to recover from a seizure?
Some people recover immediately while others may take minutes to hours
to feel like their usual self. The type of seizure, as well as what part of the brain the seizure impacts, affects the recovery period – how long it may last and what may occur during it.
What part of the brain is damaged from seizure?
Seizures can occur anywhere in the brain, but in children they frequently occur in the
temporal and frontal lobes
, affecting the functions that these regions control. A region of particular importance in adults with epilepsy, but less so in children, is the mesial, or middle, part of the temporal lobe.
What happens to brain after seizure?
During a seizure, there is
a sudden intense burst of electricity that disrupts how the brain usually works
. This activity can happen on one small part of the brain and last for just a couple of seconds, or it can spread right across the brain and keep going for many minutes.
Why do seizures damage the brain?
These studies have shown that certain populations of brain cells may die after single or repeated brief seizures.
Molecular signals inside nerve cells lead to their death
. Researchers have identified many of the chemical pathways where this occurs.
Do people remember seizures?
In focal aware seizures (FAS), previously called simple partial seizures, the person is conscious (aware and alert) and will usually know that something is happening and will remember the seizure afterwards. Some people find their focal aware seizures hard to put into words.
What are the chances of having a second seizure?
The chance of another seizure can range from
16% to 61%
, depending on the circumstances surrounding the seizure and results of a neurological exam or other tests.
Is it normal to have memory loss after a seizure?
You may have difficulty remembering information straight after a seizure. This is sometimes called post-ictal confusion and it usually goes away once you have recovered
. The length of time it takes for memory to return to normal can vary from person to person.
Do seizures show up on MRI?
Does epilepsy show up on MRI scans?
No, not necessarily
. An MRI scan can help your doctor understand some of the possible underlying structural causes of your seizures. However, for many people there is no structural cause behind their epilepsy and so the brain scan comes back ‘normal’.
Can seizures lead to dementia?
People with epilepsy develop Alzheimer’s disease at a rate 6 times higher than the non-epileptic population, and
seizures can damage the memory centers of the brain and contribute to dementia
.
Can a seizure change your personality?
When epilepsy affects you for long periods, you may notice changes in your behavior, your feelings, and in how you see the world
. Feelings of depression or anxiety are especially common. A few people with epilepsy experience psychosis (losing contact with reality).
Are seizures curable?
There’s currently no cure for epilepsy
, but it can be managed with medications and other strategies.
How long is too long for a seizure?
Over the last several decades, the length of seizure that is considered as status epilepticus has shortened. Years ago, a seizure needed to last longer than 20 minutes to be considered status epilepticus. In the last few years, it is now defined as any seizure
greater than 5 minutes
.
What damage can seizures cause?
Scientific evidence and research have long shown that prolonged seizures can kill brain cells and cause other damage. More recent research also suggests that smaller, recurring seizures can also contribute to
nerve cell injury within the brain
.
How long does memory loss last after a seizure?
Post-ictal effects can last for days
One study found that memory generally recovered
about an hour
after a seizure; however, note Fisher and Schacter in a 2000 review, “This does not explain why a considerable number of patients say they have trouble thinking for many hours or even days.”
What does a brain seizure feel like?
These seizures may alter emotions or change the way things look, smell, feel, taste or sound, but you don’t lose consciousness. You may suddenly feel
angry, joyful or sad
. Some people have nausea or unusual feelings that are difficult to describe.
Can seizures cause a stroke?
CONCLUSIONS: Our findings show that
the onset of seizures in late life is associated with a striking increase in the risk of stroke
. Further research is warranted to assess the benefit of specific interventions to prevent stroke in patients with seizures.
Are seizures painful?
In general,
the actual experience of having a seizure does not hurt
. Pain during seizures is rare . Some types of seizures make you lose consciousness. In this case, you won’t feel pain during the seizure.
How do you prevent a second seizure?

Can seizures come back?
A seizure can happen to you just once, or over and over.
If they keep coming back, that’s epilepsy, or a seizure disorder
. Less than 1 in 10 people who have a seizure get epilepsy.
Why do I have a seizure once a month?
Catamenial epilepsy (CE), also known as menstrual seizures, is
linked to a woman’s menstrual cycle and related hormone levels in the body
. Women with CE often have more seizures during certain times of their cycle.
