Study Notes
Epilepsy
- A chronic neurological disorder characterized by recurrent seizures
- Affects approximately 1% of the global population
- Can be caused by genetic mutations, head trauma, infections, or unknown factors
- Diagnosis typically involves a combination of medical history, physical examination, and diagnostic tests (EEG, MRI, CT scans)
Seizure Types
-
Generalized seizures
- Affect both sides of the brain
- Types:
- Tonic-clonic (grand mal): convulsions, loss of consciousness
- Absence (petit mal): brief, sudden loss of consciousness
- Myoclonic: sudden, brief muscle contractions
- Tonic: stiffness, rigidity
-
Partial seizures
- Affect one side of the brain
- Types:
- Simple partial: no loss of consciousness
- Complex partial: altered consciousness
- May progress to generalized seizures
Symptoms
-
Pre-seizure symptoms
- Auras (sensory or emotional experiences)
- Anxiety, dizziness, or other warning signs
-
During a seizure
- Loss of consciousness
- Muscle contractions or relaxations
- Convulsions, tremors, or rigidity
- Altered sensory experiences
-
Post-seizure symptoms
- Confusion, disorientation
- Fatigue, headache, or pain
- Memory lapses or confusion
Treatment Options
-
Medications
- Anticonvulsants to reduce seizure frequency and severity
- Examples: carbamazepine, phenytoin, valproate
-
Surgery
- Resective surgery: removal of affected brain tissue
- Disconnective surgery: separation of abnormal brain tissue
-
Dietary therapies
- Ketogenic diet: high-fat, low-carbohydrate diet
- Modified Atkins diet: modified ketogenic diet
-
Lifestyle changes
- Stress management
- Regular sleep schedule
- Avoiding seizure triggers (e.g., flashing lights)
