Study Notes
Seizure Causes and Characteristics
- The likely cause of seizures is abnormal electrical activity in the brain.
Epilepsy vs. One-Time Seizure
- Epilepsy is characterized by recurrent seizures, distinguishing it from a one-time seizure.
Consequences of Seizures
- When seizures occur, the immediate consequence is a temporary disruption of normal brain function.
Types of Seizures
- Partial seizures are characterized by abnormal electrical activity in a specific area of the brain.
- Generalized seizures involve most or all of the brain.
Generalized Seizures
- During tonic-clonic seizures, the person experiences complete loss of consciousness.
- Tonic-clonic seizures are characterized by convulsions and loss of consciousness.
Absence Seizures
- Absence seizures are characterized by a brief loss of consciousness and a blank stare.
Treatment of Seizure Disorders
- The aim of treatment for seizure disorders through drugs is to control seizures and minimize side effects.
First Aid for Seizures
- The recommended first aid step for someone experiencing a seizure is to roll them onto their side in a safe position.
Seizures vs. Epilepsy
- Seizures are a symptom, while epilepsy is a neurological disorder characterized by recurrent seizures.
Status Epilepticus
- Status epilepticus is a life-threatening condition characterized by continuous seizures without recovery between seizures.
