Causes of Seizures
Simple Causes: There are some simple conditions that can cause seizures or seizure-like movements:
- Febrile convulsions. These are fever-related seizures, usually in children, and usually a full body seizure (although sometimes a focal seizure).
- Muscle cramps. Over-exertion of a muscle can lead to a muscle spasm or cramp, that’s normal, but there are also some abnormal causes of muscle cramps (e.g. undiagnosed diabetes)
- Hypoglycemic attack (diabetic hypo, insulin reaction, etc.)
- Sleep-related spasms (sleep myoclonus). Occasional twitches, muscle jerks, or spasms occurring at the onset of sleep. These are usually normal.
Brain Causes of Generalized Seizures: Although epilepsy is well-known for causing generalized (tonic-clonic) seizures, there are a variety of causes of fits and full seizures. Many of these causes are very serious:
- Epilepsy
- Idiopathic epilepsy
- Stroke
- Transient Ischemic Attack
- Cerebral Palsy
- Brain injury (head injury)
- Brain infection (encephalitis)
- Herpes simplex encephalitis
- Meningitis
- Brain aneurysm
- Brain tumor
- Temporal lobe tumor
- Brain abscess
- High Intracranial Pressure (High ICP)
- Neurofibromatosis (brain tumors)
- Sarcoidosis (brain tumors)
- Congenital defect
- Encephalopathy
- Hypertensive encephalopathy (hypertension)
- Hepatic encephalopathy (liver disease)
- Hypoxic encephalopathy
- Metabolic encephalopathy
Other Major Causes of Seizures: Problems in other organs of the body can result in effects on the brain that are severe enough to cause seizures:
- End-stage renal failure
- Sarcoidosis
- Multiple Sclerosis
- Reye’s Syndrome
- Sturge-Weber Syndrome
- Eclampsia (pregnancy-related hypertension)
- Hyponatremia (low sodium levels)
- Hypoparathyroidism
- Porphyria
- Psychogenic seizures
Substance-Related Causes: Various drugs, medications and substances can affect the brain, causing generalized seizures:
- Alcohol Withdrawal (Delirium Tremens)
- Barbiturate withdrawal
- Cocaine abuse
- Lead poisoning
- Arsenic poisoning
- Drug side-effects
- Drug interactions
- Contrast agent side-effects (diagnostic tests)
- Vaccination side-effect. Modern vaccines are much less likely to cause a reaction.
Absence Seizures: Mental seizures where a child may “stare into space” or become non-responsive, are called absence seizures. They are often mistaken for inattention, such as inattentive-type ADHD. Causes may include:
- Epilepsy (certain types)
- Absence status
Other Notable Syndromes: There are a few disorders that don’t really cause “seizures” as such, but can cause some effects or motor disorders that are similar or related.
- Restless legs syndrome
- Parkinson’s Disease
- Essential Tremor
- Motor Disorders (generally)
- Narcolepsy. Causes sudden “sleep attacks” that can seem similar to mental seizures.
- Cataplexy. This disorder involves sudden attacks of lack of muscle tone.
- Sleep paralysis. This causes brief moments of total paralysis before sleep and on waking.
Similar Symptoms: See also the causes of symptoms similar to seizures, such as:
- Convulsions
- Fits
- Tics
- Twitches
- Muscle spasms
- Fainting
- Syncope
- Chorea
- Clonus
- Myoclonus
- Spasticity
- Involuntary movements

When are seizures not epilepsy?
While any seizure is cause for concern, having a seizure does not by itself mean a person has epilepsy. First seizures, febrile seizures, nonepileptic events, and eclampsia (a life-threatening condition that can occur in pregnant women) are examples of conditions involving seizures that may not be associated with epilepsy. Regardless of the type of seizure, it’s important to inform your doctor when one occurs.
Source: NINDS (NIH)1
• • •
Other nonepileptic events may be caused by narcolepsy (sudden attacks of sleep), Tourette syndrome (repetitive involuntary movements called tics), cardiac arrhythmia (irregular heart beat), and other medical conditions with symptoms that resemble seizures. Because symptoms of these disorders can look very much like epileptic seizures, they are often mistaken for epilepsy.

Older Adults
Epidemiological studies demonstrate that the elderly are at a substantially higher risk for the development of the epilepsies. In addition to stroke (hemorrhagic and ischemic), seizures in the elderly may be associated with brain tumors, TBI, and Alzheimer’s disease.

Non-Epileptic Seizures: An estimated 5 to 20 percent of people diagnosed with epilepsy actually have non-epileptic seizures (NES), which outwardly resemble epileptic seizures, but are not associated with seizure-like electrical discharge in the brain.

Angelman syndrome: By around two years of age … Children with Angelman syndrome may also start to have seizures (fits) around this age.

Reflex anoxic seizures: Reflex anoxic seizures are involuntary, aren't dangerous and don't cause brain damage or death. They're not a sign of a difficult child or poor parenting. They're not epileptic seizures.

Anemia: Iron deficiency anaemia
In some cases, blue breath-holding spells and reflex anoxic seizures may be linked to iron deficiency anaemia.
This is where a lack of iron in the body leads to a reduction in the number of red blood cells, causing symptoms such as tiredness, shortness of breath, heart palpitations and a pale complexion.
Source: NHS Choices UK8
• • •
Reflex anoxic seizures (RAS): The child will often open their mouth as if they're going to cry, but make no sound before turning pale grey and losing consciousness.
They'll either become limp - or, more often, stiff - with their eyes rolling upwards and their fingers clawed. Their body may also jerk a few times.
The seizure usually lasts less than a minute. Afterwards, the child will regain consciousness, but may appear sleepy and confused for a few hours.

Neurofibromatosis type 1: Around 7% of children with NF1 develop epilepsy, where a person has repeated seizures or fits. This tends to be a mild form of epilepsy that's controlled easily with medication.

Infantile spasms: Some young children experience a more serious condition, known as infantile spasms, where they have lots of seizures over a short space of time, and brain activity is abnormal all the time. These usually develop during the first year of life.
