Temporal Lobe Seizure - Symptoms And Causes
Overview Temporal lobe seizures begin in the temporal lobes of your brain, which process emotions and are important for short-term memory. These functions may cause symptoms such as fear, euphoria and deja vu.
Sometimes, focal seizures with impaired consciousness are called temporal lobe seizures. Some people can still be aware of the situation, while others might not. In more severe seizures, it is possible to appear alert but become unconscious. Sometimes, your hands and lips may perform repetitive, unintentional movements.
Although temporal lobe seizures can be caused by an anatomical defect, scar or injury in the temporal lobes, it is not always clear what causes them. Temporal lobe seizures can be treated with medication. Some people may need surgery if they don't respond well to medication.
Unusual sensations (auras) can precede temporal-lobe seizures. They are meant to be a warning sign. Some people have auras. Not all aura sufferers remember having them.
An aura is actually the beginning of a focal seizure, before consciousness is affected. Some examples of auras are:
- An unprovoked feeling of fear, joy, or panic.
- The feeling of having a deja vu moment - the sensation that something is happening before.
- Unusual or unusual odors or tastes
- Feeling like you are on a rollercoaster, a rising sensation in your abdomen
Temporal lobe seizures can sometimes affect your ability to communicate with others. This temporal-lobe seizure can last between 30 seconds to 2 minutes.
Here are the signs and symptoms that characterize these characteristics:
- Sensitivity to the environment is lost
- Start staring
- Lip smacking
- Repetitive swallowing and chewing
- You may experience unusual movements with your fingers, like picking.
A temporal lobe seizure can cause:
- There is a lot of confusion.
- Recalling what took place during the seizure is difficult
- A lack of awareness that you have had a seizure
- Extreme insomnia
Extreme cases may see a temporal seizure develop into a generalized, tonic-clonic seizure (grand Mal) characterized by convulsions or loss of consciousness.
When should you see a doctor?
If any of these symptoms occur, seek immediate medical attention.
Seizures last for more than 5 minutes. After the seizure ends, consciousness or breathing doesn't resume. A second seizure follows immediately. The seizure ends, but recovery does not end. The recovery process is more slow than normal after a seizure. A high fever is a sign of heat exhaustion. You're experiencing heat exhaustion. You're pregnant. Diabetes is a possibility. The seizure has caused you injury. Seek medical attention if you have a seizure the first time.
In these situations, seek medical assistance
- If your child or you have seizures, please let us know.
- If the severity or number of seizures rises significantly, without any explanation
- Seizures can be triggered by new signs and symptoms
There are many causes
There are four lobes on each side of the brain. The brain's frontal and middle lobes are important in cognitive function, as well as controlling or initiating voluntary movements. The temperature, taste and touch information is processed by the parietal, while vision is handled by the occipital. The temporal and occipital lobes process memories by integrating them into sensations such as taste, sound, sight, touch, smell, hearing, and touch.
The cause of temporal-lobe seizures is often not known. They can occur due to a variety of causes, such as:
- Traumatic brain injury
- An infection such as meningitis and encephalitis.
- The process of scarring, called "gliosis", in an area of the temporal brain known as the hippocampus.
- Malformations of blood vessels in the brain
- Brain tumors
- Genetic disorders
Your brain cells create varying amounts of electrical activity in normal sleeping and waking. An abnormally synced electrical activity within many brain cells can cause a seizure.
A focal seizure is one that occurs in one part of the brain. One of these seizure types is the temporal brain seizure.
Recurrent temporal-lobe seizures (or repeated ones) can lead to the shrinkage of the brain's memory and learning area, the hippocampus. Memory problems may result from brain cell death in this region.
