What is a focal onset impaired awareness seizure?A focal onset seizure begins in one side of the brain. We used to call these partial seizures. Focal onset seizures are the most common type of seizures in adults with epilepsy. When the seizure begins in one side of the brain and the person has a change in their level of awareness during some or all of it, it is called a focal onset impaired awareness seizure. The word "onset" is optional.
Learn about seizures with no loss of awareness, called focal onset aware seizures (previously simple partial seizures) here. Where do focal impaired awareness seizures (complex partial seizures) usually start?
What does a typical focal impaired awareness seizure look like?Here’s a typical story of someone having a focal onset impaired awareness (complex partial) seizure: "Susan's seizures usually occur while she's asleep. She makes a grunting sound, as if she's clearing her throat. Then she'll sit up in bed, open her eyes, and stare. She may clasp her hands together. If I ask her what she's doing, she doesn't answer. After a minute or so, she lies down and goes back to sleep."
Who is at risk for focal impaired awareness seizures (complex partial seizures)?Anybody can get them. They may be more likely in people who have had a head injury, brain infection, stroke, or brain tumor. Often though, the cause is unknown. How can I tell if someone is having a focal onset impaired awareness seizure? How often will they happen?Focal impaired awareness (complex partial) seizures sometimes resemble either daydreaming or generalized non motor (absence) seizures.

What should I do if I think my loved one or myself may have focal impaired awareness seizures?If you think your loved one or yourself may be having focal impaired awareness seizures, let your doctor know your concerns right away. Untreated seizures can lead to injury, significant memory impairment, and in rare cases physical injury or death.
What is the outlook for people with focal impaired awareness seizures (complex partial seizures)?
If seizures are not controlled, consider seeking a consultation from a neurologist that specializes in epilepsy (called an epileptologist). An evaluation at a comprehensive epilepsy center can help evaluate all treatment options. Learn More

People who have a complex partial seizure are not usually aware of their surroundings while it happens. They will not respond to others or their environment, and they do not typically remember what occurs during the episode.
What are the three categories of partial seizures?These seizures are also called partial seizures.. Simple focal seizures affect a small part of the brain. ... . Complex focal seizures can make a person with epilepsy confused or dazed. ... . Secondary generalized seizures begin in one part of the brain, but then spread to both sides of the brain.. What is a partial epileptic seizure?A partial (focal) seizure happens when unusual electrical activity affects a small area of the brain. When the seizure does not affect awareness, it is known as a simple partial seizure. Simple partial seizures can be: Motor - affecting the muscles of the body. Sensory - affecting the senses.
What is the difference between partial and generalized seizures?Seizures can be categorized as partial or generalized. Seizures originating from a single location in the brain are considered to have a focal onset, known as a partial seizure. Seizure activity originating simultaneously from bilateral hemispheres is considered to have a generalized onset.
