EEG is required to distinguish myoclonic seizures from nonictal causes of myoclonus, which can arise from lesions of the cortex, brainstem, spinal cord, or even peripheral nerve (see Workup). [emedicine.medscape.com]

Treatment
Some of the services we provide include: • Brachial Plexus Palsy treatment • Cerebral Palsy treatment • Epilepsy treatment • General Neurology treatment • Movement Disorders treatment • Neurofibromatosis Center treatment • Stroke treatment • Tuberous [neuro.wustl.edu]
Treatment with anticonvulsants is usually effective in controlling the attacks. BFIS results in generalized tonic-clonic and complex partial seizures that typically occur in clusters between 3-24 months of age. [genedx.com]
There are many manifestations of epilepsy and, therefore, a diversity of factors in underlying pathology, responses to treatment and prognosis. [books.google.de]
Shorter duration between the onset of IS and initiation of standard treatment appears to lead to an improved outcome; therefore early recognition of the seizures and early treatment are essential. [childneurologyfoundation.org]
Prognosis
Prognosis The prognosis depends heavily on the underlying etiology and the epilepsy syndrome. Patients with a benign syndrome typically respond well to medication and may outgrow their epilepsy. [emedicine.medscape.com]
Prognosis The prognosis for children with IS is largely dependent on the underlying cause. The intellectual prognosis for children with IS is generally poor because many babies with IS have neurological impairment prior to the onset of spasms. [childneurologyfoundation.org]

Pathophysiology
Pathophysiology Myoclonic seizures are generally the product of hypersynchronous, generalized cortical discharges. These discharges arise from hyperexcitable neuronal networks. [emedicine.medscape.com]
The author presents clinical and EEG manifestations, epidemiology, pathophysiology, differential diagnosis, and management of this rather benign early onset idiopathic myoclonic epilepsy. [medlink.com]
Although the exact pathophysiology is unknown, mutations in cystatin B appear to lead to accelerated apoptosis, which may explain the progressive neurologic decline [ Delgado-Escueta et al., 2001 ]. [clinicalgate.com]

In addition, parents should also be aware that these drugs may prevent recurrences but do not alter the long-term prognosis for attaining seizure remission. [aafp.org]
