Epilepsy is a disease that causes abnormal electrical signals in the brain, impairing one's ability to function normally. One of the most common types of seizures associated with epilepsy is myoclonic seizures, which are brief, shock-like jerks of a muscle or group of muscles. Myoclonic seizures can cause quick, uncontrollable muscle jerks or spasms and are usually minor. They can occur at any age but are more common in childhood seizure conditions. Epileptic spasms can also be classified as symmetric, asymmetric, focal, or subtle spasms, and they typically occur in a series, especially upon waking up.

What You'll Learn
Myoclonic seizures
These seizures can be treated with anti-seizure medications, which can help lower or prevent them. However, it may take a few tries to find the right drug and dosage. Surgery may be an option if medications cannot control the seizures. It is important to see a doctor quickly for a diagnosis and to begin treatment as myoclonic seizures can worsen over time.

Myoclonus vs. epileptic spasms
Myoclonus is a type of uncontrollable movement that includes sudden, brief involuntary twitching, jerking, or spasms of a single muscle or a group of muscles. Myoclonus is not a disease in itself but may be a sign of another neurological condition. Myoclonus can happen in situations that are not associated with any severe illness and are, in fact, fairly common. For example, a hypnic jerk is a sudden muscle twitch or spasm that occurs as one is falling asleep.
Myoclonic seizures are brief, shock-like jerks of a muscle or a group of muscles. They are a type of myoclonus that happens because of an underlying epileptic condition in the brain. In epilepsy, myoclonic seizures usually cause quick jerking movements on both sides of the body at the same time. They occur in a variety of epilepsy syndromes that have different characteristics. For instance, Juvenile myoclonic epilepsy (JME) seizures usually involve the neck, shoulders, and upper arms. Myoclonic seizures can occur as single events or in clusters, with several occurring over a short time. They are more likely under certain circumstances, such as when a person is very tired or hasn't slept, or when they feel stressed or anxious. Myoclonic seizures can be treated with antiepileptic drugs such as levetiracetam, valproic acid, and zonisamide.
Epileptic spasms are a sudden flexion, extension, or mixed flexion-extension of proximal and truncal muscles, lasting 1-2 seconds. They typically occur in a series, usually upon waking. Subtle forms may only involve chin movement, grimacing, or head nodding. Epileptic spasms may be bilaterally symmetric, asymmetric, or unilateral, depending on whether they are generalized onset or focal onset. They may also occur as a later feature in a seizure, rather than at the onset.

Epileptic spasms in children
Infantile spasms, also known as West syndrome, epileptic spasms, or infantile spasms syndrome, are a kind of epilepsy that usually begins in children under one year old. They are considered an age-specific epilepsy, typically starting between 3 and 8 months of age, with most cases beginning by 1 year of age. Infantile spasms are not common, affecting only one in a few thousand babies.
Children with infantile spasms typically experience clusters of short seizures or spasms, which may be subtle and easily confused with normal baby behaviours or colic. The spasms often manifest as a sudden, brief stiffening of the baby's muscles, with the body bending forward, the knees pulled up, and the arms thrown out to the side. Each spasm usually lasts about one second and tends to repeat in a cluster, with a single spasm occurring every 5 to 15 seconds over several minutes. The movement during a spasm may include a quick wide-eyed stare, dropping of the head, and raising of the shoulders and arms.
The underlying cause of infantile spasms can vary. In some cases, there may be a structural change in the brain due to a prior injury, such as a brain infection or lack of oxygen to the brain. It can also be caused by a change in the way the brain has developed, known as cortical malformation or dysplasia. Genetic and metabolic causes can also lead to infantile spasms, affecting brain function and resulting in seizures.
Diagnosing and treating infantile spasms is crucial and urgent. If left untreated, the disorder can permanently impair the child's development. To diagnose infantile spasms, healthcare professionals examine the child's movements and perform an electroencephalogram (EEG) to analyse their brain waves. Many children with infantile spasms will exhibit a characteristic pattern on their EEG called hypsarrhythmia. Once diagnosed, further testing is conducted to determine the underlying cause, including MRI scans, blood work, and genetic studies.
The primary treatments for infantile spasms include hormonal therapy and vigabatrin, an anti-seizure medication. Steroid therapy, including prednisone/prednisolone or adrenocorticotropic hormone (ACTH), is also used. If initial treatments are ineffective, other anti-seizure medications may be considered, such as valproate (Depakote), topiramate (Topamax), pyridoxine (vitamin B6), or clonazepam (Klonopin). However, these medications are less effective than steroids, ACTH, and vigabatrin.

Epileptic myoclonus
Myoclonus refers to a quick, sharp muscle movement that often looks like a twitch or a spasm. Myoclonic seizures are brief, shock-like jerks of a muscle or a group of muscles. The term "myoclonus seizure" is used if myoclonus results from abnormal brain activity. In epilepsy, myoclonic seizures usually cause quick jerking movements on both sides of the body at the same time.
Myoclonic seizures can occur as single events or in clusters, with several occurring over a short time. They can be easily overlooked because they are so brief and appear as extra normal movements. These seizures can be mistaken for tics, tremors, or clumsiness. Myoclonic seizures can occur in people without epilepsy, for example, as a hypnic jerk when falling asleep. However, in epilepsy, myoclonic seizures usually cause quick, jerking movements on both sides of the body at the same time. Juvenile myoclonic epilepsy (JME) seizures usually involve the neck, shoulders, and upper arms and can be triggered by being overtired or flashing lights. JME is a common form of childhood generalized (genetic) epilepsy, making up about 5% to 10% of all epilepsy cases.
Myoclonic seizures can be treated with anti-seizure (anti-epileptic) medications. It may take a few tries to find the right drug and amount. Surgery may be an option if medications cannot control the seizures. A vagus nerve stimulator (VNS) is sometimes implanted and used with anti-epileptic medication to lower seizures.

Epileptic spasms treatment
Myoclonic seizures are a type of epileptic seizure that causes brief, shock-like jerks of a muscle or a group of muscles. They are usually minor and are more common with childhood seizure conditions. Myoclonic seizures can occur as single events or in clusters, with several occurring over a short time. They can be easily overlooked because they are so brief and appear as extra normal movements. However, they can sometimes result in someone dropping an object or, less commonly, cause a fall.
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. The word "myoclonic" combines the Greek prefix for muscle, "myo", with "clonus", which means twitching. Myoclonic seizures do not cause any loss of awareness—the person is awake and conscious during the seizure.
There are several medicines that can help prevent myoclonic seizures. Myoclonic seizures often respond well to the appropriate medication. It is important to see a doctor quickly to make a diagnosis and begin treatment. Epilepsy centers provide teams of specialists to help diagnose epilepsy and explore treatment options.
Focal onset epileptic spasms are particularly important, as the identification of a structural cause can allow for curative epilepsy surgery to be considered. Clues to a focal origin of epileptic spasms include asymmetry of the motor features, lateral head/eye version, and the presence of focal structural brain abnormalities.
