Study Notes
Seizure Classifications
- Tonic–clonic seizures: Characterized by loss of consciousness and dramatic muscle contractions; can occur at any age; common seizure type; recovery period follows the seizure.
- Absence seizures: Involves brief periods of loss of consciousness without muscle contractions; typically starts around age 3; common in childhood; lasts about 3 to 5 seconds and typically benign but can disrupt learning.
- Myoclonic seizures: Sporadic muscle contractions lasting several minutes; relatively rare; can be secondary to other conditions; may require further medical investigation.
- Febrile seizures: Triggered by high fevers, often observed in preschool children; usually self-limited with no recurrence; commonly seen in young children.
- Jacksonian seizures: Spread from one area of the brain to other parts of the body; may allow memory retention of the initial phase.
- Psychomotor seizures: Involve sensory and motor components with a loss of memory; longer and more complex seizure events.
- Status epilepticus: Continuous state of seizures with no recovery; considered the most dangerous seizure condition.
Seizure Characteristics
- Loss of Consciousness: Tonic–clonic and absence seizures both involve loss of consciousness, but absence seizures lack muscle contractions.
- Duration: Absence seizures last only a few seconds while tonic–clonic seizures have recovery periods and myoclonic seizures can last for several minutes.
- Memory Retention: Absence and psychomotor seizures usually involve no memory post-event. Jacksonian seizures may retain memory of the initial phase.
Complications and Triggers
- Complications: Status epilepticus poses the greatest risk due to rapid recurrence; myoclonic seizures may necessitate further medical investigation, while absence seizures could disrupt learning.
- Onset Triggers: Myoclonic seizures are often secondary, febrile seizures are triggered by high body temperatures, and absence seizures occur spontaneously without obvious triggers.
Age Groups Associated with Seizures
- Tonic–clonic seizures can occur at any age.
- Absence seizures typically start around age 3.
- Febrile seizures most frequently occur in preschool children.
- Status epilepticus can affect individuals of any age.
Summary of Key Points
- Tonic–clonic seizures are very common, while absence seizures are also frequent during childhood.
- Myoclonic seizures are the least common type.
- Febrile seizures are a common response in young children to high fevers.
- Recognition of these classifications aids in effective diagnosis and treatment for seizure disorders.
