What is Hemiconvulsion hemiplegia?

Hemiconvulsion-Hemiplegia (HH) syndrome is an uncommon consequence of prolonged focal febrile convulsive seizures in infancy and early childhood. It is characterized by the occurrence of prolonged clonic seizures with unilateral predominance occurring in a child and followed by the development of hemiplegia.

What is HHE syndrome?

Hemiconvulsion-hemiplegia-epilepsy (HHE) syndrome involves initial sudden and prolonged unilateral convulsive seizures, followed by transient or permanent hemiplegia and epilepsy during infancy or early childhood.

What type of seizure is status epilepticus?

A seizure that lasts longer than 5 minutes, or having more than 1 seizure within a 5 minutes period, without returning to a normal level of consciousness between episodes is called status epilepticus. This is a medical emergency that may lead to permanent brain damage or death.

Can seizures cause hemiplegia?

What is the connection between Epilepsy and Hemiplegia? Hemiplegia and epilepsy are often related to an abnormal formation in the brain or an alteration in the activity of the brain. In some cases, the brain damage that causes hemiplegia may also cause epilepsy.

What is severe myoclonic epilepsy in infancy?

Severe Myoclonic Epilepsy in infancy (SMEI, or Dravet syndrome) is a drug-resistant epilepsy that occurs in the first year of life of previously healthy children. The main clinical features are prolonged and repeated febrile and afebrile generalized or unilateral convulsive seizures.

What is a unilateral seizure?

A unilateral seizure can indicate that the seizure is a “focal” seizure, meaning it originates in one part of the brain and stays in that part of the brain. Seizures that arise from both sides of the brain (called “generalized” seizures) may lead to symptoms occurring on both sides of the body (bilateral).

What are the symptoms of status epilepticus?

These are possible symptoms of status epilepticus:

  • Muscle spasms.
  • Falling.
  • Confusion.
  • Unusual noises.
  • Loss of bowel or bladder control.
  • Clenched teeth.
  • Irregular breathing.
  • Strange behavior.

Does status epilepticus go away?

Status epilepticus (SE) is a very severe type of seizure. For someone who has seizures, they’re normally similar in length each time they occur and typically stop once that time period has passed.

What are the symptoms of hemiplegia?

Hemiplegia symptoms

  • muscle weakness or stiffness on one side.
  • muscle spasticity or permanently contracted muscle.
  • poor fine motor skills.
  • trouble walking.
  • poor balance.
  • trouble grabbing objects.

What is mild hemiplegia?

Hemiparesis is a mild or partial weakness or loss of strength on one side of the body. Hemiplegia is a severe or complete loss of strength or paralysis on one side of the body. The difference between the two conditions primarily lies in severity. They can both be: the result of the same causes.
