Focal Aware Seizures (Simple Partial) Lecture Notes

Overview of Focal Aware Seizures

  • Definition: Focal seizures start on one side of the brain. Previously known as partial seizures.
  • Focal Aware Seizures: When there is no confusion or loss of awareness. Previously called simple partial seizures.

Who is at Risk?

  • Anyone can develop focal aware seizures.
  • Higher risk in individuals with:
    • Head injury
    • Brain infection
    • Stroke
    • Brain tumor
  • Often, the cause is unknown.

Experiences During a Focal Aware Seizure

  • 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.
  • Awareness: Individuals remain fully alert and can recall events.
  • Symptoms:
    • Shaking in one part
    • Abnormal sensations
    • Sudden nausea
    • Visual symptoms like flashing lights
  • Typically brief, lasting less than 2 minutes.

Other Conditions Mimicking Focal Aware Seizures

  • Conditions with similar symptoms:
    • Nausea or pain related disorders
    • Hallucinations
    • Dja vu experiences
    • Transient ischemic attack (TIA)
    • Migraines

Post-Seizure Behavior

  • Individuals usually continue with their activities.
  • Can serve as an aura for stronger seizures.

Frequency of Occurrence

  • Varies significantly among individuals.

Diagnosis

  • Medical History & Physical Exam: To exclude other causes.
  • EEG: May not always show seizure discharges.
  • Imaging: MRI or CT scans to detect structural brain issues.

Treatment Options

  • Medications: Anti-seizure medicines.
  • Devices: Various devices to manage seizures.
  • Surgery: In some cases.
  • Dietary Therapy: Special diets can help manage seizures.
  • Specialist Consultation: Consider seeing an epileptologist or visiting an epilepsy center.

Steps if Concerned About Seizures

  • Notify a doctor for accurate diagnosis and treatment planning.
