| Cause | Simple Explanation |
|---|---|
| Head trauma | Brain injury from accidents |
| Encephalitis | Infection/inflammation of the brain |
| High fever | Especially in children (febrile seizures) |
| Brain tumor | Abnormal growth pressing on brain tissue |
| Hypoglycemia | Blood sugar too low |
| Hyponatremia | Blood sodium too low |
| Hypocalcemia | Blood calcium too low |
| Extreme acidosis/alkalosis | Blood pH severely abnormal |
| Drug withdrawal | Stopping alcohol or sedatives suddenly |
| Birth trauma | Brain injury at birth |
| Idiopathic | No known cause (the most common in epilepsy) |
Key point: If seizures are caused by a temporary problem (like fever or low sugar), fixing the cause stops the seizures. Only repeated unprovoked seizures = epilepsy.
| Strategy | Meaning in Simple Words |
|---|---|
| Modify ion channels | Block sodium (Na+) or calcium (Ca2+) channels so neurons can't fire abnormally |
| Increase GABA activity | Boost the brain's natural "braking" chemical (GABA = inhibitory neurotransmitter) |
| Decrease glutamate activity | Reduce the brain's main "accelerator" chemical (glutamate = excitatory neurotransmitter) |
| Drug | How it Works |
|---|---|
| Cannabidiol (CBD) | From Cannabis plant (non-psychoactive). Mechanism unknown. Oral bioavailability only 13-19%. Metabolized by CYP2C19. Caution with clobazam (excess sedation). |
| Stiripentol | Positive allosteric modulator of GABA-A receptors. Reduces frequency of prolonged seizures in children. Non-linear kinetics. |
| Fenfluramine | Amphetamine derivative. Inhibits serotonin uptake. Effective for convulsive seizures in Dravet and atonic seizures in Lennox-Gastaut syndrome. |
| Drug | Mechanism |
|---|---|
| Zonisamide | Mechanism not fully known |
| Rufinamide | Mechanism not fully known |
| Levetiracetam / Brivaracetam | Binds to SV2A protein (synaptic vesicle protein) - reduces neurotransmitter release |
| Vigabatrin | Irreversible GABA-transaminase inhibitor (already covered above) |
| Drug | Main Use | Key Mechanism | Big Side Effect |
|---|---|---|---|
| Phenytoin | Partial, GTC | Na+ block | Gum overgrowth, teratogen |
| Carbamazepine | Partial, GTC | Na+ block | Blood disorders |
| Valproate | Broad spectrum | Na+ block + GABA | Liver toxicity, teratogen |
| Ethosuximide | Absence only | T-type Ca2+ block | GI upset |
| Phenobarbital | Partial, GTC, infants | GABA-A (Cl-) | Sedation |
| Clonazepam | Absence, myoclonic | GABA-A (Cl-) | Sedation |
| Lamotrigine | Partial, generalized | Na+ block | Rash |
| Topiramate | Broad spectrum | Na+ + GABA + AMPA | Cognitive slowing |
| Vigabatrin | Partial, West's | GABA-T inhibitor | Psychosis |
| Gabapentin/Pregabalin | Partial (adjunct) | Unknown/GABA alter | Dizziness |
| Perampanel | Partial | AMPA block | Aggression |
| Cannabidiol | Dravet, Lennox-Gastaut | Unknown | Liver enzymes |

Medical educational flowchart titled "Classification of Epileptic Seizures". Clean white background with color-coded branches. Top box: "EPILEPTIC SEIZURES" in dark blue. Two main branches below: Left branch in teal: "PARTIAL (FOCAL) SEIZURES - One side of brain" splitting into two sub-boxes: "A. SIMPLE PARTIAL (Jacksonian) - Consciousness PRESERVED - One limb/muscle group - Motor, sensory or speech disturbance - EEG: Contralateral discharge" and "B. COMPLEX PARTIAL (Temporal Lobe) - Consciousness IMPAIRED/LOST - Automatisms (lip smacking, hand movements) - Confused/dazed behavior - EEG: Bilateral spread". Right branch in orange: "GENERALIZED SEIZURES - Both brain hemispheres" splitting into six sub-boxes arranged vertically: "1. TONIC-CLONIC (Grand Mal) - Tonic phase: rigid stiffening - Clonic phase: rhythmic jerking - Loss of consciousness", "2. ABSENCE (Petit Mal) - Blank stare 5-10 sec - No falling - Eyelid flutter - EEG: 3/sec spike-wave", "3. TONIC - Sustained muscle stiffening", "4. CLONIC - Rhythmic jerking only", "5. ATONIC (Drop Attack) - Sudden loss of muscle tone - Patient falls", "6. MYOCLONIC - Sudden brief muscle jerk". At the bottom a red warning box: "STATUS EPILEPTICUS - Seizures lasting 30+ min without recovery - MEDICAL EMERGENCY". All text clear and readable, professional medical infographic style.
Medical educational diagram titled "How Antiseizure Drugs Work at the Synapse" showing a detailed neuron synapse illustration. Dark navy blue background with bright colored labels. Center shows a presynaptic neuron terminal on top and postsynaptic neuron membrane at bottom with synaptic cleft in between. Label the following components with colored arrows and drug names: 1) Voltage-gated Na+ channels on neuron membrane - red label: "Na+ CHANNEL BLOCKERS: Phenytoin, Carbamazepine, Lamotrigine, Valproate, Oxcarbazepine, Topiramate, Lacosamide - Block rapid firing" 2) T-type Ca2+ channels - orange label: "Ca2+ CHANNEL BLOCKERS: Ethosuximide - Blocks thalamic oscillation in Absence seizures" 3) GABA vesicles releasing into synapse - green label: "GABA ENHANCERS" with sub-labels: "Barbiturates (Phenobarbital) - Keep Cl- channel OPEN LONGER" and "Benzodiazepines (Clonazepam) - Open Cl- channel MORE OFTEN" and "Vigabatrin - Block GABA breakdown enzyme" and "Tiagabine - Block GABA reuptake" 4) Glutamate/AMPA receptors on postsynaptic - purple label: "GLUTAMATE BLOCKERS: Perampanel, Topiramate, Felbamate - Block AMPA receptors" 5) SV2A protein on vesicle - yellow label: "SV2A MODULATORS: Levetiracetam, Brivaracetam". Bottom text: "GABA = Brain Brakes (Inhibitory) | Glutamate = Brain Accelerator (Excitatory)". Clean professional medical illustration style.
Medical educational flowchart titled "Drug Selection by Seizure Type" on clean white background.
