What are the causes of myoclonic seizures?

Too many causes: Benign myoclonus can occur in children and adolescents. Jme is fairly common in young people - especially girls. Severe metabolic disorders will cause myoclonus, and anoxic brain damage can also cause myoclonus. A severe complex seizure disorder can develop in children and young adults - lennox gastaut - that may cause severe episodes of myoclonus and drop attacks. ...Read more

What causes onset of complex partial seizures?

What causes onset of complex partial seizures?

Miswiring: Complex partial seizures involve alterations of consciousness without generalization of motor symptoms to involve the whole body. Any structural irritant in the brain can cause a complex partial seizure. Examples are infections, tumors, abnormal blood vessels, and strokes. Also, there are genetic causes of complex partial seizures that are due to miswiring in the brain. ...Read more

What are the causes of a grand mal seizure?

What are the causes of a grand mal seizure?

Altered brain signal: Grand mal seizures occur when the electrical activity over the whole surface of the brain becomes abnormally synchronized. In general, seizures are caused by abnormal, rhythmic nerve cell (neuron) activity in the brain. The brain's nerve cells normally communicate with each other by sending electrical and chemical signals across the synapses that connect the cells.This is altered in seizures. ...Read more

Genetic causes of epilepsy that lead to an abnormality in excitability of neurons or miswiring of connections can cause seizures. Also, any scar or lesion on the brain can cause seizure. Infections and other conditions that alter the body's normal chemistry can cause seizures. ...Read more

What are the symptoms of myoclonic epilepsy?

Muscle spasms: Seizures usually have a stiff tonic phase followed by rhythmic jerking or clonic phase. Myoclonic spasms can be isolated and independent. Infants may have a series of painful spasms especially upon awakening. Adolescents may have morning spasms and even drop or throw their toothbrush. Lennox-gastaut patients may have massive spasms or drop attacks that are myoclonic. Difficult to treat. ...Read more

What are the differences between tonic-clonic seizures, simple partial seizures, and complex partial seizures?

What are the differences between tonic-clonic seizures, simple partial seizures, and complex partial seizures?

Accurate description: The best way to define a seizure is to view it from start to finish with all sensory and motor events recorded as well as the on-going eeg. If it starts in one area of the brain, it is partial. If it starts all over, it is generalized. If there is alteration of consciousness, it is complex. Grand mal should not be used. ...Read more

Is monoclonal epilepsy, tonic clonic seizure, tonic seizure and clonic seizure are the same ( grand mal)?

Is monoclonal epilepsy, tonic clonic seizure, tonic seizure and clonic seizure are the same ( grand mal)?

No: Juvenile moloclonal epilepsy is a generalized epilepsy, which occurs in the age group from 12-16yo. Grand mal seizures are usually generalized type of seizures and has two phases. In the tonic phase, loss of conciousness occurs and muscle contraction causes the person to fall down. The clonic phase is the rhythmic contraction of muscles, alternating b/w flexion and relaxation.

Why are seizures a symptom of gliomas?

Brain damage.: Gliomas are tumors of the brain. They arise from glial cells, which are part of the support structure of the brain. As the tumors enlarge, they press on and irritate brain cells. That can make the normal brain cells give off electical impulses, and if there is too much activity, involving too many cells, a seizure will occur. ...Read more

What causes severe myoclonic jerks?

What causes severe myoclonic jerks?

Numerous causes: Brief list: normal jerks on falling asleep, but problem if it awakens (plms). Associated with epilepsy (juvenile myoclonic), spinal cord inflammation (aid's), following hypoxia (lance-adams), organ failure (kidney, liver), metabolic and medication reactions. Meds that seem to work best here include depakote, keppra, (levetiracetam) and maybe lamictal. Other drugs used in epilepsy, may make worse. ...Read more

Began generic Keppra (levetiracetam) XR on Aug 8 for myoclonic seizures & having high increase in psych Sx. Could med be cause? If so, ALT options for Tx of seizures?

Began generic Keppra (levetiracetam) XR on Aug 8 for myoclonic seizures & having high increase in psych Sx. Could med be cause? If so, ALT options for Tx of seizures?

Seizure tretaments: Keppra (levetiracetam) can definitely cause psych-related side effects. There are a large number of anti-seizure medications and it is important to share these symptoms with your neurologist and find a medicine that gives you a balance between proper seizure control and minimal side effects. ...Read more

How to tell if myoclonic jerks are a seizure my child has these all through the night some nights but how to tell what's normal from myoclonic epileps?

Neurologist?: As a physician it is through the descriptions that the patient makes that one can start to determine if they are meaningful. I would video these movements that you have concerns about and show them to your physician or pediatric neurologist. This would be very helpful and then if necessary further tests can be done to determine if they are seizures. ...Read more

My daughter is having many episodes of myoclonic jerking when awake but EEGs and MRIs are normal. Could it still be seizures?

No: Myoclonus is a movement disorder not a seizure disorder, it can be physiologic; normal with no clinical significane, it can laso be related to other problems of the neurologic system. Keep requested follow up with the neurologist for continued monitoring overtime to determine if other symptoms will develope or if your child's movements are physiologic. Take care. ...Read more

What is the difference between a myoclonic seizure and myoclonic epilepsy?

Seizure v epilepsy: The easy answer is that epilepsy is a condition of two or more unprovoked seizures. A myoclonic seizure is a single event, myoclonic epilepsy is the tendency to continue to have myoclonic seizures. Normally the two of these are associated though, since most people who have myoclonic seizures have myoclonic epilepsy or a similar form of epilepsy. ...Read more

Can you tell me in the summer I was diagnosed with juvenlie myoclonic epilepsy could a seizure happen at night?

First...: Although possible, it is DISTINCTLY uncommon to begin having seizures due to JME at 42. The syndrome comes on a puberty, and is genetic (autosomal dominant with variable penetrance). Second...yes. Although people with JME more often have seizures shortly after awakening, some can have seizures at night. I'd make sure an epilepsy subspecialist concurs with diagnosis. ...Read more

I was diagnosed with juvenile myoclonic epilepsy. Are seizures more likely to happen at night or in the afternoon?

Myoclonic seizures: are most likely to occur around the time of awakening. Other seizure types associated with JME can occur in sleep more than when awake (focal seizures, GTC, secondarily generalized GTC) Absence seizures tend to be brought out by hyperventilation if they occur at all. No two cases, to me, are identical making diagnosis a bit tricky. Best of luck. (Treat with Depakote, Keppra (levetiracetam) or Lamictal) ...Read more

May have inherited epilepsy--generalized seizures on awakening, teen onset-- partial seizures with weird jaw sensation, too--possible myoclonic jerk?

?JME?: Not sure of your precise question, but will attempt an analysis. You may possess juvenile myoclonic epilepsy, and if correct, your best drugs might be either Depakote or keppra, (levetiracetam) (lamictal may not work quite as well here. Yet, you may be sub-therapeutic based on your description). Also, you seem to have several complexities, and i wonder how all these inter-relate. Go over this with neurologist. ...Read more
