Partial-Onset Seizures
Partial-Onset Seizures: Overview
Partial-onset seizures, or focal seizures, are the most common type of seizure disorder. Focal seizures start in one specific area of the brain and affect the body differently than generalized seizures. Partial-onset seizures can be broken down into two types: simple partial seizures and complex partial seizures.
Simple Partial Seizures
Simple partial seizures are also known as "simple partial epilepsy." During these seizures, the person is usually conscious and aware of their surroundings. These seizures may cause physical symptoms, such as twitching, jerking, or feeling a strange sensation in one part of the body. They may also cause sensory, cognitive, and emotional symptoms, such as hearing or seeing things that aren't there, or feeling scared, anxious, or confused.
Complex Partial Seizures
Complex partial seizures are also known as "complex partial epilepsy." During these seizures, the person is not typically conscious or aware of what is happening. They may exhibit behaviors such as blank staring, lip smacking, or repeating certain actions over and over, such as hand rubbing or picking at clothing. Although the person may not be aware of their actions, they still may have physical sensations, such as tingling, or emotional feelings, such as fear or confusion.
Diagnosis and Treatment
Partial-onset seizures are typically diagnosed through electroencephalography (EEG) tests and other medical tests. Treatment options vary depending on the type and severity of seizures, and may include medications, surgery, or other treatments. It is important to speak to your doctor to get an accurate diagnosis and develop an appropriate treatment plan.
Signs and Symptoms of Partial-Onset Seizures
The signs and symptoms of partial-onset seizures can vary and may include:
- Uncontrollable twitching or jerking of a part of the body
- Changes in vision
- Confusion or disorientation
- Unusual behavior or emotions
- Loss of consciousness
- Loss of bladder or bowel control
If you or someone you know is experiencing any of these symptoms, it is important to seek medical attention right away. Do not attempt to diagnose or self-treat the condition. Treatment is available for partial-onset seizures and the earlier a diagnosis is made, the more effective treatments can be.
