What is the medical definition of a seizure?
A chronic progressive loss of neurons causing memory decline.
A sudden, uncontrolled electrical disturbance in the brain.
A brief halt in blood supply to brain tissue.
A prolonged muscular contraction lasting minutes.
A seizure is defined as a sudden, uncontrolled electrical disturbance in the brain that can cause changes in behavior, movements, or consciousness. This is distinct from vascular or muscular conditions. Seizures may be focal or generalized depending on the brain regions involved. Epilepsy Foundation
Which of the following best describes a tonic-clonic seizure?
Sudden muscle stiffening followed by rhythmic jerking of all limbs.
Brief staring episodes with no rhythmic movements.
Localized twitching in a single limb without awareness change.
A transient loss of muscle tone causing collapse.
Tonic-clonic seizures involve an initial tonic phase of muscle stiffening followed by a clonic phase of rhythmic jerking affecting most of the body. They are the most recognized seizure type and often last 1–3 minutes. Awareness is usually lost during these events. Mayo Clinic
Which symptom is commonly experienced as an “aura” before a seizure?
Visual disturbances such as flashing lights or shapes.
Sharp chest pains accompanied by sweating.
Intense joint pain in moving limbs.
Chronic headache persisting for days.
An aura is a subjective sensory warning that can precede some seizures, often manifesting as visual disturbances like flashing lights, strange smells, or tingling sensations. It represents focal seizure activity awareness before progression. Recognizing an aura can help a person prepare for an imminent seizure. Epilepsy Foundation
What distinguishes epilepsy from a single seizure event?
Epilepsy is diagnosed after two or more unprovoked seizures; a seizure can be an isolated incident.
A single seizure always indicates epilepsy.
Epilepsy only occurs in response to fever.
A seizure must last over 10 minutes to be considered epilepsy.
Epilepsy is a chronic neurological condition marked by a predisposition to generate spontaneous, unprovoked seizures, typically diagnosed after two or more such events. A single seizure may result from a specific acute cause and does not necessarily indicate epilepsy. Differentiation involves medical history and diagnostic testing. CDC
Which lifestyle factor is a well-known trigger for seizures?
Sleep deprivation or irregular sleep patterns.
High intake of dietary fiber.
Moderate daily exercise.
Regular hydration with water.
Sleep deprivation and disrupted sleep patterns reduce seizure threshold and are common triggers in individuals with epilepsy. Ensuring adequate and consistent sleep is a key preventive strategy. Other lifestyle factors like stress and alcohol use also play roles. Epilepsy Foundation
How are focal seizures different from generalized seizures?
Focal seizures begin in a specific area of the brain and may affect one body part.
Focal seizures always involve loss of consciousness and entire body convulsions.
Generalized seizures start in one small brain region.
Generalized seizures never affect awareness.
Focal seizures originate in a localized region of the brain and may result in motor, sensory, or autonomic symptoms in one part of the body. They can occur with or without impairment of awareness. Generalized seizures involve bilateral brain networks from seizure onset. Mayo Clinic
What is the most important first aid step during a seizure?
Protect the person’s head and remove nearby hazards.
Restrict the person’s movements to stop jerking.
Force fluids into the person’s mouth to prevent biting.
Administer anti-seizure medication immediately.
During a seizure, safety is paramount: protecting the person’s head and clearing the area of dangerous objects helps prevent injury. Restraining movements or forcing objects into the mouth increases risk of harm. Medication administration depends on medical training and prescription. Red Cross
Which age group is most susceptible to febrile seizures?
Children aged 6 months to 5 years.
Adolescents aged 13 to 18 years.
Adults aged 20 to 40 years.
Elderly over 65 years old.
Febrile seizures most commonly occur in children between 6 months and 5 years old due to rapid temperature changes during febrile illnesses. They are typically benign and often outgrown by school age. Underlying neurological conditions are rare in simple febrile seizures. NINDS
Status epilepticus is defined as a seizure or series of seizures lasting longer than how many minutes?
5 minutes.
1 minute.
10 minutes.
30 minutes.
Status epilepticus is a neurological emergency characterized by continuous seizure activity lasting more than 5 minutes, or recurrent seizures without recovery between episodes. Early intervention is critical to prevent long-term brain injury. Treatment guidelines emphasize rapid treatment within this timeframe. Epilepsy Foundation
Which diagnostic test directly measures the brain’s electrical activity to help diagnose seizure disorders?
Electroencephalogram (EEG).
Magnetic resonance imaging (MRI).
Computed tomography (CT) scan.
Positron emission tomography (PET) scan.
An EEG records electrical impulses from the brain via surface electrodes, detecting abnormal patterns typical of seizure disorders. While MRI and CT give structural images, they do not directly measure electrical activity. PET scans assess metabolic processes but are less commonly used for initial seizure diagnosis. Epilepsy Foundation
In which scenario should emergency medical services be contacted during a seizure?
If the seizure lasts longer than 5 minutes without stopping.
If the person regains full awareness immediately after.
If the seizure is focal and brief under 30 seconds.
If the person can speak during the seizure.
A seizure lasting longer than 5 minutes meets criteria for status epilepticus, a life-threatening emergency requiring immediate medical attention. Short, focal seizures that resolve quickly often do not require EMS. Speaking ability during a seizure is not a reassuring sign without timing context. Epilepsy Foundation
Which medication is considered a first-line treatment for generalized tonic-clonic seizures?
Valproic acid.
Carbamazepine.
Ethosuximide.
Levetiracetam.
Valproic acid is widely used as a first-line therapy for generalized tonic-clonic seizures due to its broad-spectrum efficacy. Carbamazepine is preferred for focal seizures but may worsen some generalized types. Ethosuximide is indicated for absence seizures. Levetiracetam is another broad-spectrum agent but often considered after first-line options. NCBI
Photosensitive epilepsy is triggered by which of the following stimuli?
Flashing or flickering lights.
Loud, sudden noises.
Strong odors.
Cold temperatures.
Photosensitive epilepsy is a form of reflex epilepsy where seizures are precipitated by visual stimuli such as flashing or flickering lights at certain frequencies. Loud noises or odors do not provoke this particular type. Protective measures include avoiding known light triggers. Epilepsy Foundation
What characteristic defines a complex focal seizure?
Impaired awareness with possible automatisms like lip-smacking.
Brief loss of tone leading to drooping head.
Generalized stiffening and jerking of all limbs.
Short staring spells without motor activity.
Complex focal seizures (now termed focal impaired awareness seizures) impair consciousness and often include automatisms like lip-smacking or hand movements. They differ from simple focal seizures, which preserve awareness, and from generalized seizures that involve both hemispheres initially. Epilepsy Foundation
What term describes a seizure that occurs in direct association with an acute brain insult?
Provoked seizure.
Unprovoked seizure.
Idiopathic seizure.
Refractory seizure.
A provoked (or acute symptomatic) seizure arises in close temporal relation to an acute brain insult such as stroke, head injury, or metabolic disturbance. Unprovoked seizures occur without immediate precipitating factors. Idopathic implies no known cause, and refractory refers to medication-resistant seizures. Epilepsy Foundation
What does the acronym SUDEP stand for in epilepsy care?
Sudden Unexpected Death in Epilepsy.
Seizure Under Diagnostic Evaluation Protocol.
Severe Uncontrolled Deficit Epilepsy Prediction.
Sudden Unilateral Damage in Epilepsy.
SUDEP stands for Sudden Unexpected Death in Epilepsy, describing the sudden, unexplained death of a person with epilepsy without a clear structural or toxic cause found post-mortem. It is a serious concern, prompting research into prevention strategies. Risk factors include uncontrolled generalized seizures. Epilepsy Foundation
Lennox-Gastaut syndrome is primarily characterized by which seizure type?
Atonic (drop) seizures.
Typical absence seizures.
Simple focal seizures.
Epilepsia partialis continua.
Lennox-Gastaut syndrome is a childhood epileptic encephalopathy marked by multiple seizure types, most notably atonic seizures, which cause sudden loss of muscle tone and drop attacks. It also features slow spike-and-wave patterns on EEG and cognitive impairment. Management is often challenging due to refractory seizures. Epilepsy Foundation
Absence seizures typically last approximately how many seconds?
10 seconds.
1 second.
30 seconds.
60 seconds.
Absence seizures are brief generalized seizures lasting around 5 to 10 seconds, characterized by sudden staring and unresponsiveness. They often present in childhood and may occur many times per day. Longer episodes warrant evaluation for atypical absence or other seizure types. Epilepsy Foundation
Most anti-epileptic drugs exert their effects by enhancing which inhibitory neurotransmitter?
Gamma-aminobutyric acid (GABA).
Dopamine.
Glutamate.
Acetylcholine.
Many anti-epileptic medications, such as benzodiazepines and barbiturates, work by enhancing the inhibitory action of GABA, increasing neuronal inhibition, and reducing excitability. Other drugs may target sodium or calcium channels, but GABAergic mechanisms are central. NCBI
Which patient profile is most suitable for evaluation for epilepsy surgery?
A patient with focal seizures refractory to two or more medications.
A patient with well-controlled generalized seizures.
A patient with a single generalized tonic-clonic seizure.
A patient whose seizures respond to sleep hygiene changes.
Candidates for epilepsy surgery typically have focal seizures that fail to respond to two or more adequate medication trials, and a localized epileptogenic zone can be identified without unacceptable functional deficit risk. Controlled generalized seizures or provoked isolated events are not surgical candidates. Epilepsy Foundation
Vagus nerve stimulation (VNS) helps reduce seizure frequency by stimulating which anatomical pathway?
Afferent fibers modulating brainstem and cortical excitability.
Efferent sympathetic fibers to the heart.
Direct motor pathways in the spinal cord.
Peripheral sensory nerves in the limbs.
VNS delivers electrical pulses to the left vagus nerve’s afferent fibers, influencing brainstem nuclei and cortical networks, which can reduce seizure frequency and severity. The exact mechanism remains under study but involves neurotransmitter modulation and network desynchronization. Mayo Clinic
The ketogenic diet controls seizures by inducing which metabolic state?
Ketosis, which alters neuronal energy utilization.
Hyperglycemia, increasing glucose metabolism.
Hypoglycemia, lowering blood sugar levels.
Alkalosis, elevating blood pH.
The ketogenic diet is a high-fat, low-carbohydrate regimen that shifts metabolism toward fat-derived ketone bodies, creating ketosis. Ketones may have anticonvulsant effects by influencing neurotransmitter systems and neuronal excitability. It’s an established therapy, especially in drug-resistant epilepsy. Johns Hopkins Medicine
In adults, what is the most common cause of provoked (acute symptomatic) seizures?
Alcohol withdrawal.
Brain tumors.
Hypoglycemia.
Stroke.
In adult populations, withdrawal from chronic alcohol use is a leading cause of acute symptomatic (provoked) seizures due to sudden changes in neuronal excitability. Stroke and metabolic disturbances are also causes, but alcohol withdrawal is well-documented as most frequent. Epilepsy Foundation
A mutation in the SCN1A gene is most commonly associated with which epilepsy syndrome?
Dravet syndrome.
Lennox-Gastaut syndrome.
Juvenile myoclonic epilepsy.
Temporal lobe epilepsy.
Mutations in the SCN1A gene, which encodes a neuronal sodium channel subunit, are the primary cause of Dravet syndrome, a severe infantile-onset epileptic encephalopathy. This genetic diagnosis informs treatment and prognosis. NCBI
Cannabidiol (CBD) is thought to reduce seizure frequency primarily by interacting with which system or receptors?
Modulation of TRPV1 channels and GPR55 receptors in the endocannabinoid system.
Selective inhibition of GABA-A receptors.
Exclusive blockade of voltage-gated sodium channels.
Stimulation of dopamine release in the striatum.
CBD’s anticonvulsant effects are believed to involve modulation of the endocannabinoid system, particularly TRPV1 ion channels and GPR55 receptors, rather than direct CB1 activation. This mechanism alters neuronal excitability without significant psychoactivity. ScienceDirect

Cheat Sheet

  1. Classification of Seizure Types -

    According to the 2017 ILAE framework, seizures are categorized as focal (originating in one hemisphere) or generalized (involving both hemispheres simultaneously). Focal seizures may be aware or have impaired awareness and often present with sensory auras like déjà vu, while generalized seizures include tonic - clonic and absence events. Test your grasp of these definitions with a quick seizure quiz online or epilepsy quiz to boost recall.

  2. Neurophysiology: Excitation vs. Inhibition -

    A seizure arises when cortical excitatory glutamate activity overwhelms inhibitory GABA mechanisms, leading to hypersynchronous neuronal firing (Source: NIH). Remember the "E over I" ratio - excitation over inhibition - increases during seizure onset, like a seesaw tipping forward. Reinforce this concept on a seizure knowledge test to ensure you can describe the neurotransmitter balance accurately.

  3. Clinical Features and Auras -

    Motor seizures include tonic - clonic, myoclonic, or atonic movements, while non-motor (absence) seizures often manifest as brief lapses in awareness - think "petit mal" or staring spells (Mayo Clinic). Auras, such as sudden fear, visual hallucinations, or gustatory sensations, act as focal seizure warning signs. Challenge yourself on an epilepsy quiz by matching these symptoms to seizure types.

  4. EEG Signatures and Patterns -

    Electroencephalography key patterns include 3 Hz spike-and-wave discharges in absence seizures and interictal epileptiform spikes in focal epilepsy (American Epilepsy Society). Learning to identify these waveforms is akin to reading a fingerprint of brain activity. Apply your knowledge in a brain health quiz and practice spotting these signatures.

  5. Triggers and Treatment Overview -

    Common triggers like sleep deprivation, flashing lights, and alcohol withdrawal can lower the seizure threshold, summarized by the mnemonic "S-P-I-T" (Stress, Photosensitivity, Insomnia, Toxins). Acute management often begins with benzodiazepines for status epilepticus, followed by long-term antiseizure drugs such as valproate or carbamazepine (World Health Organization). Take a seizure test online to connect trigger avoidance strategies with the appropriate therapeutic interventions.
