A seizure is a neurological disorder (brain disorder). Seizure is caused because of disturbances in electrical signalling in the brain. Generalised tonic-clonic seizures are the most common type of seizure. Symptoms and treatment of a seizure depends on the type of seizures. Seizures due to epilepsy can be controlled with anti-epileptic medications in most patients.
The duration of seizure is influenced by many factors including the type of seizures, compliance with treatment, etc. Seizures in epilepsy cannot be cured, but prevented with medications. Seizures may be difficult to control because of some underlying brain disease. In most children, febrile seizures stop by the age of 5 years. Seizures because of excess alcohol consumption, infection, low blood sugar or low blood calcium are controlled well with treatment of the underlying condition.
Treatment of seizures depends on the cause of seizure. Seizures caused due to conditions, such as low blood sugar, low blood calcium, etc do not need anti-epileptic medications, but the treatment of the underlying cause is vital. Seizures due to epilepsy can be controlled with anti-epileptic medications in most patients with the currently available medications and other treatment options.
Prognosis of seizures depends on the type and cause of seizure. Seizure because of a treatable condition, such as alcohol dependency, infection, low blood sugar or low blood calcium has good prognosis. Seizure because of epilepsy can be controlled in up to 70% of newly diagnosed cases (both children and adults) with anti-epileptic drugs.
Consult a doctor for seizure if you experience seizure for the first time while on medication or have bothersome side-effects of medications. Women with any type of seizure should consult a doctor before planning pregnancy or if seizure occurs during pregnancy.
There is no one specific way in which all types of seizures in everyone can be prevented. Some ways in which seizure or worsening of seizures can be prevented include taking your medications as recommended, avoiding trigger factors (if known), preventing head injuries, treating associated medical conditions, relaxing and sleeping adequately, etc.
Seizure can be diagnosed clinically based on history. Tests may done to confirm the cause of seizures. Some of the tests that may be done include electroencephalography (EEG), brain imaging (CT, MRI, PET) and blood tests. EEG is the most frequently used test after the fist seizure. Brain imaging tests are useful to identify many problems in the structure of the brain including tumours, cysts and infection that may be the cause of seizures.
There are many types of seizures and symptoms depend on the type of seizure. In generalised seizure, the person losses consciousness and the entire body is affected by seizure. Symptoms of generalised tonic-clonic seizure include loss of consciousness and stiffness of the entire body initially followed by rapid twitching of the arms and legs. Symptoms of partial seizure include involuntary jerking or twitching of part of the body with or without loss of consciousness.
