Study Notes
Overview of Epilepsy
- Epilepsy is a brain disorder characterized by recurrent seizures, caused by temporary disruptions in electrical activity.
- Approximately 3% to 3.5% of Australians will be diagnosed with epilepsy during their lifetime, with over 250,000 currently living with the condition.
- Diagnosis can occur at any age, but it is most commonly identified in children and seniors.
- Types of epilepsy vary significantly among individuals; some may outgrow their seizures while others experience lifelong symptoms.
- About two-thirds of those with epilepsy can achieve seizure freedom through medication.
Causes of Epilepsy
- Anyone can develop epilepsy regardless of age or culture; it is caused by damage to brain tissue that impacts neuronal communication.
- Common causes include:
- Head injuries or trauma
- Stroke or brain hemorrhage
- Oxygen deprivation during events like birth trauma or heart attacks
- Infections affecting the brain
- Brain tumors
- Other potential causes include:
- Congenital brain abnormalities
- Genetic predispositions
- Neurodegenerative diseases such as Alzheimer’s
- Substance abuse (alcohol or drugs)
- In many cases, the exact cause of epilepsy remains unknown.
Impact of Causes on Treatment
- Understanding the cause of epilepsy can inform treatment options and expectations for seizure management.
- Determining the cause may lead to a better understanding of the seizure types and their potential responsiveness to medications.
Seizures
- Seizures occur due to disruptions in normal electrical impulses in the brain, resulting in rapid firing of neurons.
- Symptoms can manifest as changes in sensation, consciousness, emotions, behavior, or movement, depending on seizure origin.
- Seizures can vary in severity and duration, with most lasting less than two minutes, although some can extend to three minutes or more.
Seizure Triggers
- Seizure triggers are distinct from the underlying causes of epilepsy; they are specific occurrences or conditions that can provoke a seizure.
- Identifying individual seizure triggers can help manage and potentially reduce seizure occurrences.
- Common triggers include:
- Missed medication doses
- Sleep deprivation
- Physical exhaustion
- Emotional stress or excitement
- Hormonal changes (e.g., menstruation)
- Illness or fever
- Poor dietary habits or low blood sugar levels
- Visual stimuli like flickering lights or distinct patterns
