How does a seizure affect the brain?
How does a seizure affect the brain?
Prolonged seizures are clearly capable of injuring the brain. Isolated, brief seizures are likely to cause negative changes in brain function and possibly loss of specific brain cells.
What damage do seizures cause?
Seizures, particularly repetitive seizures, cause substantial brain damage in highly susceptible areas, such as parts of the hippocampus, entorhinal cortex, amygdala, thalamus and other limbic structures; however, neuronal death after seizures can be more widespread and is generally quite variable (e.g., [24, 77]).
What happens to brain after seizure?
You may keep having some symptoms even after the seizure activity in your brain has stopped. This is because some symptoms are after-effects of a seizure, like sleepiness, confusion, certain movements or being unable to move, and difficulty talking or thinking normally.
What are the long term effects of a seizure?
Long lasting seizures, or status epilepticus, may also cause brain damage or death. People with epilepsy are eight times more likely than people without it to experience certain other chronic conditions, including dementia, migraine, heart disease, and depression.
How long does it take to feel normal after a seizure?
As the seizure ends, the postictal phase occurs – this is the recovery period after the seizure. Some people recover immediately while others may take minutes to hours to feel like their usual self.
What happens to the brain after seizure?
What are the long-term effects of seizures on the brain?
Eventually, reoccurring seizures can cause damage to the memory areas of the brain and result in permanent memory loss. The effects of epilepsy on memory can affect both the areas that store visual memories as well as those that store verbal memories. The long-term effects of epilepsy on memory can result in language and speech difficulties as well.
How dangerous are seizures?
Most seizures are not dangerous on their own. However, seizure-like activity can result in injury due to falls or can limit activities that the person is able to engage in (for example driving, swimming, climbing ladders, etc) in which a sudden loss of consciousness could be dangerous.
What are the effects of having a seizure?
A seizure usually affects how a person looks or acts for a short time. Someone having a seizure might collapse, shake uncontrollably, or even just stare into space. All of these are brief disturbances in brain function, often with a loss of or change in consciousness.
What happens to the brain after a seizure?
A number of experimental studies indicate that seizures can cause brain damage. Seizures are clearly capable of injuring the brain and are likely to cause negative changes in brain function. They may also result in the loss of specific brain cells.
