What is Epilepsia Partialis Continua?
Overview. A seizure happens when electrical activity in the brain surges suddenly. Epilepsia partialis continua (EPC) is a condition that occurs when seizures happen every few seconds or minutes. This can continue for days, weeks or even years. EPC seizures are most common in the hands and face (focal).
Can focal seizures be seen on EEG?
Focal seizures are associated with specific EEG patterns, that aid in detecting and discerning the focus and subsequently the treatment for the specific epileptic syndrome. This activity reviews the application, technique used, and common EEG findings in localizing epilepsies.
What does status epilepticus look like on EEG?
The EEG in myoclonic status epilepticus may show generalized, bisynchronous polyspikes, spikes, or sharp waves preceding and time-locked with the clinical myoclonus, superimposed on a diffusely slow and suppressed background. A burst-suppression pattern may also be seen.
Do simple partial seizures show on an EEG?
Scalp EEG commonly shows no change in simple partial seizures, because the focal ictal discharge is distant or deep, or involves too small a neuronal aggregate for synchronised activity to register on the scalp. This is unfortunate given how difficult diagnosis of simple partial seizures can be on clinical grounds.
What are the 4 types of epilepsy?
Epilepsy is a common seizure disorder. There are four main types of epilepsy: focal, generalized, combination focal and generalized, and unknown. A doctor generally diagnoses someone with epilepsy if they have had two or more unprovoked seizures.
How often do myoclonic seizures occur?
Myoclonic seizures often happen in everyday life. This includes hiccups and a sudden jerk while falling asleep. The condition is not epilepsy unless there are more than two seizures happening repeatedly over time.
How do I read my EEG results?

How long after a seizure will EEG detect it?
Conclusion: The diagnostic yield of EEG following a first unprovoked epileptic seizure is highest when this test is performed within the first 16 h after onset of the event.

What is the mildest form of epilepsy?
Absence seizures (formerly called “petit mal” seizures) are very brief and do not cause the person to fall or have significant shaking movements. Typical absence seizures involve a sudden cessation of movement, with staring and sometimes with blinking.
What triggers epilepsy?
What are some commonly reported triggers?
- Specific time of day or night.
- Sleep deprivation – overtired, not sleeping well, not getting enough sleep, disrupted sleep.
- Illness (both with and without fever)
- Flashing bright lights or patterns.
- Alcohol – including heavy alcohol use or alcohol withdrawl.
Can myoclonic seizures be seen on an EEG?
Electroencephalographic Findings
Myoclonic seizures are typically associated with generalized spike-and-wave or multiple spike-and-wave discharges on the EEG. Myoclonic seizures are frequently associated with enhanced photosensitivity.
Does myoclonus show up on EEG?
Commonly, EEG has been considered as a helpful tool in the diagnosis of myoclonic seizure, and polyspike-slow wave consisting of polyspikes followed by slow wave is usually characterized.
What is an abnormal EEG test results?
An abnormal EEG means that there is a problem in an area of brain activity. This can offer a clue in diagnosing various neurological conditions.
What are 10 conditions diagnosed with an EEG?
10 Conditions Diagnosed With an EEG
- Seizure Disorders. The primary use of EEG is diagnosing epilepsy and other seizure disorders.
- Sleep Disorders. Sleep disorders range from insomnia to narcolepsy.
- Brain Tumors. There are many types of brain tumors.
- Brain Injury.
- Dementia.
- Brain Infections.
- Stroke.
- Attention Disorders.
What is a normal EEG result?
Most waves of 8 Hz and higher frequencies are normal findings in the EEG of an awake adult. Waves with a frequency of 7 Hz or less often are classified as abnormal in awake adults, although they normally can be seen in children or in adults who are asleep.
How accurate is an EEG for seizures?
Based upon our positive likelihood ratios, and assuming a pre-test probability of 50%, an adult with ED on routine EEG after a first unprovoked seizure has a 77% probability of having a second seizure, whilst a child with similar findings has a 66% probability.
What are normal EEG results?
What is silent epilepsy?
Overview. Absence seizures involve brief, sudden lapses of consciousness. They’re more common in children than in adults. Someone having an absence seizure may look like he or she is staring blankly into space for a few seconds.
What foods should you avoid if you have epilepsy?
white bread; non-wholegrain cereals; biscuits and cakes; honey; high-sugar drinks and foods; fruit juices; chips; mashed potatoes; parsnips; dates and watermelon. In general, processed or overcooked foods and over-ripe fruits.
What foods should epileptics avoid?
What are the warning signs of epilepsy?
Symptoms
- Temporary confusion.
- A staring spell.
- Stiff muscles.
- Uncontrollable jerking movements of the arms and legs.
- Loss of consciousness or awareness.
- Psychological symptoms such as fear, anxiety or deja vu.
Do myoclonic seizures cause brain damage?
It can be the most disabling form of myoclonus affecting the arms, legs, and face. One of the causes may be brain damage that results from a lack of oxygen and blood flow to the brain, or it can be secondary to other medical or neurological conditions.
What is the difference between a myoclonic jerk and myoclonic seizure?
Symptoms of Myoclonic Seizures
The mechanism is similar to a myoclonic jerk, the sudden spasm occasionally experienced by people as they are falling asleep. However, unlike myoclonic jerks, the “jolts” of myoclonic seizures occur in bouts.
Is a myoclonic jerk a seizure?
Myoclonic seizures are characterized by brief, jerking spasms of a muscle or muscle group. They often occur with atonic seizures, which cause sudden muscle limpness.
