A complex partial seizure is a type of seizure that arises in one lobe of the brain, rather than the whole brain. The seizure affects people’s awareness and may cause them to lose consciousness. Complex partial seizures are now more commonly referred to as focal onset impaired awareness seizures or focal impaired awareness seizures.
A partial seizure is a surge of electrical activity in just one area of the brain. These seizures are also known as focal onset seizures. A focal seizure can happen for a number of different reasons, so determining the underlying cause is the key to proper treatment. People who suffer from partial seizures or focal onset seizures experience a lot of physical symptoms, including muscle contractions, visual disturbances, and even blackouts. All of this can be rather frightening.
