Focal Length - focal legnth
The symptoms vary depending on what part of the brain they come from. For example, symptoms can involve shaking of one part of the body, an abnormal sensation in one part of the body, sudden onset of nausea, flashing lights or visual symptoms, etc. In most people, the symptoms are very similar from seizure to seizure.

Your health care provider can help determine whether your symptoms may be focal aware (simple partial) seizures or some other condition. Your provider will consider:

When the seizure begins in one side of the brain and the person has no confusion or loss of awareness of their surroundings during it, it is called a focal aware seizure. This type of seizure was previously called a simple partial seizure.

It depends. Focal aware seizures vary a lot in how often they occur – some people can have them daily while in others they may be much less common.
A focal seizure begins in one side of the brain. They were previously called partial seizures. Focal onset seizures are the most common type of seizures experienced by people with epilepsy. For short, the term focal seizure can be used.
Although electroencephalograms (EEGs) are also helpful, they may not always show seizure discharges during a focal aware seizure. EEG shows abnormal electrical discharges if present at the time of the EEG. However, absence of EEG changes does not rule out seizures.
Several treatment options are available that can help prevent further focal onset aware seizures from occurring, including

A brain MRI (magnetic resonance imaging) or CT (computed tomography) scan may show an underlying cause for seizures. MRI and CT show structural problems in the brain, which would be present even between seizures.

When a focal aware seizure ends, the person usually continues doing whatever they were doing before it started. This type of seizure can be a warning or aura before a stronger seizure with loss of consciousness. Care and comfort first aid is all that is needed when a person has a focal aware seizure.
A complete medical history and physical examination can help rule out other possible causes of the symptoms and assess the likelihood of epilepsy.
If you think that you or loved one may have focal aware seizures, it is important to let your doctor know right away. Seek help to get an accurate diagnosis and treatment plan.

Learn about seizures with loss of awareness, called focal impaired awareness seizures (previously complex partial seizures).
When people have focal aware seizures, they are fully awake, alert, and able to recall events during the seizure. Some are "frozen" during the seizure, so they may or may not be able to respond to others during the seizures. Overall, these seizures are brief, usually lasting less than 2 minutes.
You may not be able to tell because the person is fully alert and able to interact. The person may need to tell you what is happening.
Anybody can get focal aware seizures. They may be more likely in people who have had a head injury, brain infection, stroke, or brain tumor. Yet many times the cause is unknown.
