Partial Seizures

Seizures can be broken down into two different categories with subcategories partial or generalized. 

Partial seizures begin with an electrical discharge in one limited area of the brain. Some are related to head injury, brain infection, stroke, or tumor, but in most cases the cause is unknown.

One question that is used to further classify partial seizures is whether consciousness (the ability to respond and remember) is "impaired" or "preserved." The difference may seem obvious, but really there are many degrees of impairment or preservation of consciousness.

Identifying certain seizure types and other characteristics of a person's epilepsy like the age at which it begins, for instance, allows doctors to classify some cases into epilepsy syndromes. This kind of classification helps us to know how long the epilepsy will last and the best way to treat it.

  • Simple partial seizures
    • Characterized by strange sensations, such as smell particular odors, restless movement, hearing issues, stomach problems, or enhanced sense of fear
  • Complex partial seizures
    • Complex partial Seizures are preceded by an “aura”, which can occur in the form of a sensation, numbness, fear, dizziness, or stomach discomfort.  In addition to a loss of awareness, memory, or control. 
  • Secondarily generalized seizures
    • Secondarily generalized seizures start as a partial seizure. It starts in one limited area of the brain, but then the seizure spreads throughout the brain, becoming "generalized." The generalized, convulsive phase of these seizures usually lasts no more than a few minutes, the same as primary generalized seizures. The preceding partial seizure is usually not very long. Sometimes this part is so brief that it is hard to detect. These seizures occur in more than 30% of people with partial epilepsy.
