Comprehensive Nursing Notes: Understanding Convulsions
A detailed guide for nursing students on assessment, management, and care
Table of Contents
Introduction to Convulsions
A convulsion is a medical condition where body muscles contract and relax rapidly and repeatedly, resulting in an uncontrolled shaking of the body. Convulsions are physical manifestations of abnormal electrical activity in the brain and are characterized by sudden, brief attacks of altered consciousness, motor activity, and sensory phenomena.
The terms “convulsion” and “seizure” are often used interchangeably, though technically a convulsion refers specifically to the motor components of a seizure that involve muscle contractions. Not all seizures involve convulsions, but all convulsions are considered a type of seizure.
Epilepsy is diagnosed when a person has two or more unprovoked seizures. While epilepsy always involves seizures, not all seizures indicate epilepsy. Convulsions can be isolated events triggered by various factors including high fever, head injury, or metabolic disturbances.
For nursing students, understanding the mechanisms, types, and management of convulsions is crucial for providing effective care to affected patients and potentially preventing complications or further seizure activity.
Key Terminology
- Convulsion: Uncontrolled muscle contractions causing shaking movements
- Seizure: A sudden surge of abnormal electrical activity in the brain
- Epilepsy: A chronic disorder characterized by recurrent, unprovoked seizures
- Ictal state: The period during a seizure
- Postictal state: The recovery period following a seizure
- Aura: A sensory warning that may precede a seizure
- Status epilepticus: A seizure lasting more than 5 minutes or recurrent seizures without recovery between them

Types of Convulsions/Seizures
According to the International League Against Epilepsy (ILAE) 2017 classification, seizures are categorized based on their onset, awareness level, and motor symptoms. Understanding these types helps nurses provide appropriate care and documentation.
Based on Origin
| Type | Characteristics | Clinical Manifestations | Nursing Considerations |
|---|---|---|---|
| Focal Seizures (Partial) | Start in one area of the brain | May involve sensory symptoms, motor activity, autonomic features, or altered awareness depending on brain region affected | Observe and document specific movements or behaviors to help localize the seizure focus |
| Generalized Seizures | Involve both hemispheres of the brain from the start | Usually involve loss of consciousness, widespread motor activity | Focus on airway management, preventing injury, timing the episode |
| Unknown Onset | Origin cannot be determined | May begin with unclear signs before evolving into more recognizable patterns | Detailed observation of sequence of events is crucial for later diagnosis |
Focal Seizures Subtypes
Focal Aware Seizures
Formerly called simple partial seizures
- Consciousness is preserved
- Patient remains alert and can recall events
- May experience motor symptoms (rhythmic movements), sensory symptoms (unusual smells, tastes), or autonomic symptoms (racing heart, stomach discomfort)
- Usually brief (seconds to minutes)
Focal Impaired Awareness Seizures
Formerly called complex partial seizures
- Consciousness is impaired
- Patient appears confused or dazed
- May perform repetitive movements (automatisms) like lip-smacking, chewing, or fidgeting
- Typically last 1-2 minutes
- Followed by confusion and memory gap for the event
Generalized Seizures Subtypes
| Type | Characteristics | Duration | Nursing Considerations |
|---|---|---|---|
| Tonic-Clonic (Grand Mal) | Initial stiffening (tonic phase) followed by rhythmic jerking (clonic phase); loss of consciousness; may have urinary/bowel incontinence | 1-3 minutes | Protect from injury, time the seizure, maintain airway, position on side after seizure, expect postictal confusion |
| Absence (Petit Mal) | Brief staring episodes; minimal or no motor movement; abrupt onset and cessation | 5-30 seconds | May be mistaken for daydreaming; important to document frequency; minimal postictal confusion |
| Myoclonic | Brief, shock-like muscle jerks of the face, trunk, or extremities | Seconds | Differentiate from normal startle responses; may occur in clusters |
| Tonic | Sustained muscle stiffening without clonic phase | <1 minute | High risk for falls; protect head; may cause vocalization from air forced through vocal cords |
| Atonic (Drop Attacks) | Sudden loss of muscle tone causing falls | <15 seconds | High risk for head injury; protective helmets may be needed; rapid recovery |
| Clonic | Rhythmic jerking movements without initial tonic component | Variable | Less common than tonic-clonic; protect from injury during movements |
Special Consideration: Status Epilepticus
Status epilepticus is a medical emergency defined as:
- A seizure lasting longer than 5 minutes, OR
- Multiple seizures without full recovery of consciousness between them
This condition requires immediate medical intervention to prevent neurological damage and other life-threatening complications.
Causes of Convulsions
Provoked Seizures
Provoked (acute symptomatic) seizures occur due to a specific trigger and may not recur when the trigger is removed.
- Metabolic disturbances: Hypoglycemia, hyponatremia, hypocalcemia, uremia
- Toxic: Alcohol withdrawal, drug overdose or withdrawal, carbon monoxide poisoning
- High fever: Particularly in children (febrile seizures)
- Acute infection: Meningitis, encephalitis, brain abscess
- Acute head trauma: Concussion, contusion, intracranial hemorrhage
- Sleep deprivation: Can lower seizure threshold
- Medication reactions: Some antibiotics, antipsychotics, stimulants
Unprovoked Seizures
Unprovoked seizures occur without an immediate identifiable cause and may indicate epilepsy if recurrent.
- Genetic factors: Family history of epilepsy, genetic syndromes
- Congenital abnormalities: Brain malformations, cortical dysplasia
- Acquired brain injuries: Previous stroke, traumatic brain injury
- Tumors: Primary brain tumors, metastatic lesions
- Neurodegenerative disorders: Alzheimer’s disease, multiple sclerosis
- Perinatal injuries: Birth trauma, hypoxic-ischemic encephalopathy
- Remote infections: Previous CNS infections leaving scarring
- Idiopathic: No identifiable cause (approximately 50% of epilepsy cases)
Risk Factors for Developing Epilepsy
- Family history of epilepsy
- History of febrile seizures in childhood
- Head trauma, especially with loss of consciousness
- CNS infections (meningitis, encephalitis)
- Stroke or cerebrovascular disease
- Brain tumors or abnormal brain structures
- Neurodevelopmental disorders
- Alzheimer’s disease and other dementias
- Autism spectrum disorder
- Advanced age (>65 years)
Mnemonic: “VITAMIN” for Common Seizure Causes
- V – Vascular (stroke, hemorrhage)
- I – Infections (meningitis, encephalitis)
- T – Trauma (head injuries)
- A – AV Malformations (arteriovenous abnormalities)
- M – Metabolic (electrolyte imbalances, hypoglycemia)
- I – Idiopathic (unknown causes)
- N – Neoplasms (tumors)
Pathophysiology of Convulsions
Understanding the pathophysiology of convulsions is essential for comprehending seizure manifestations and their management. Convulsions result from abnormal, excessive, and hypersynchronous electrical discharges from neurons in the brain.
Normal Neuronal Activity
In normal brain function, there is a delicate balance between excitatory and inhibitory neurotransmission:
- Excitatory neurotransmitters: Primarily glutamate, which stimulates neurons to fire action potentials
- Inhibitory neurotransmitters: Primarily GABA (gamma-aminobutyric acid), which inhibits neuronal activity
This balance allows for controlled information processing and normal brain function.
Seizure Development
During a seizure, this balance is disrupted, leading to:
- Excessive excitation (increased glutamate activity)
- Decreased inhibition (reduced GABA effectiveness)
- Alterations in ion channels (especially sodium, potassium, and calcium)
- Hypersynchronization of neuronal networks
- Formation of an epileptogenic focus (area where seizures originate)
The Seizure Process
- Initiation: Triggered by factors that lower seizure threshold or by spontaneous activity in an epileptogenic focus
- Paroxysmal Depolarization Shifts (PDS): Neurons begin to fire abnormally, creating bursts of high-frequency discharges
- Propagation: The abnormal electrical activity spreads to neighboring neurons through synaptic and non-synaptic mechanisms
-
Clinical manifestation: As different brain regions become involved, specific symptoms appear based on the affected areas:
- Motor cortex involvement → convulsive movements
- Sensory cortex involvement → sensory symptoms
- Widespread involvement → loss of consciousness
-
Termination: Eventually inhibitory mechanisms overcome excitation, ending the seizure through:
- Neurotransmitter depletion
- Energy substrate depletion
- Activation of inhibitory mechanisms
- Changes in ion channel properties
Metabolic Changes During Prolonged Seizures
Status epilepticus causes significant physiological changes:
Cerebral Effects
- Increased cerebral metabolic demand
- Increased cerebral blood flow initially
- Decreased cerebral blood flow later
- Cerebral edema
- Neuronal damage and death
Systemic Effects
- Lactic acidosis
- Hyperthermia
- Respiratory compromise
- Increased catecholamine levels
- Rhabdomyolysis
- Hypoglycemia
Postictal State
- Neuronal exhaustion
- GABA-mediated inhibition
- Altered consciousness
- Muscle soreness
- Confusion and disorientation
- Todd’s paralysis (temporary weakness)
Understanding this pathophysiology helps nurses recognize why certain symptoms occur during and after convulsions, as well as the rationale behind various treatment approaches, particularly the mechanisms of action for antiseizure medications.
Assessment of Patients with Convulsions
A comprehensive assessment is crucial for patients experiencing convulsions. Nurses play a vital role in collecting accurate information that will guide diagnosis and treatment.
History Taking
Mnemonic: “TDOC” for Seizure Documentation
- T – Type of seizure (observed characteristics)
- D – Duration (how long the seizure lasted)

Key Questions to Ask
- For witnessed seizures:
- What happened first? (aura, warning signs)
- Which body parts were involved? (focal vs. generalized onset)
- Was consciousness affected? (aware vs. impaired awareness)
- How long did it last?
- What happened after the seizure? (postictal state)
- Patient history:
- Previous seizures or diagnosis of epilepsy?
- Family history of seizures?
- Recent head trauma?
- Current medications and compliance?
- Recent illness or fever?
- Alcohol or drug use?
