The causes and types of epileptic seizures

A brain tumor or other condition that needs surgery right away A brain malformation or old injury that does not need immediate treatment When considering brain surgery, we do 2 types of brain imaging: Medicine for Seizures For almost all children with epilepsy, the first and most effective treatment is medicine.

The causes and types of epileptic seizures

Types of Seizures The difference between these types is how they begin. Focal Seizures Focal seizures previously called partial seizures start in one part of the brain and affect the part of the body controlled by that part of the brain.
Epilepsy - Types, Symptoms, Causes, Prevention and Treatment To diagnose complex partial seizures, a doctor may carry out one or more of the following: Medical history An EEG test that may be done to diagnose complex partial seizures.
What are the symptoms of a seizure? Facts in Other Languages The form, intensity, and duration of seizures are related to the number and type of brain cells affected. There are two broad types of seizures:
Focal Seizures Glossary What are the epilepsies? The epilepsies are chronic neurological disorders in which clusters of nerve cells, or neurons, in the brain sometimes signal abnormally and cause seizures.

Epilepsy causes, types and triggers What causes epilepsy? Few instances will be determined as a result of an injury to the brain. When a cause is known, it is typically as a result of: Researchers have established that up to genes, however, are linked to the condition, but not all can be definitively determined as a direct cause of epilepsy.

Some genes merely make a person more sensitive to certain seizure triggers such as environmental factors.

The causes and types of epileptic seizures

Are there different types of epilepsy? The main classification types are known as: Typically diagnosed during childhood or adolescence, this type often shows little or no nervous system abnormalities, other than seizures.

Tests may involve EEG electroencephalogram which measures electrical impulses in the brain or MRI magnetic resonance imaging scan.

Scans will show a structurally normal brain, but a specialist may be able to determine subtle changes which may have been present since birth, such as epileptic discharges affecting one or more areas of the brain.

A person with this type has normal intelligence, but will experience myoclonic seizures, absence seizures or generalised tonic-clonic seizures grand mal seizures.

This mild type is often diagnosed in early childhood between the ages of 5 and 8 and almost always is outgrown by puberty sexual maturation. A child will experience partial motor seizures affecting the face and grand mal seizures.

Diagnosis is typically made with an EEG. With a symptomatic type, a cause has been determined and often relates to widespread brain damage. A sufferer may also have other neurological problems, such as cerebral palsy or mental retardation. Where a cause has not been determined, a diagnosis will be made as cryptogenic epilepsy.

Both experience multiple types of seizures — namely, generalised tonic-clonic, tonic, myoclonic, atonic, tonic and absence.

This is often difficult to control. Sub-types include Lennox-Gastaut syndrome. Symptomatic partial focal epilepsy: Commonly diagnosed in adulthood, this type is also frequently seen in childhood.

Some abnormalities may be microscopic and difficult to pick up on an MRI scan, however some abnormalities can be seen and identified. Are there common triggers for an epileptic seizure?

Commonly noted triggers that bring on seizures among epilepsy sufferers include: Sometimes a seizure incident is brought on by a trigger, other times not. For others, a combination of factors may trigger a seizure experience. Females may also note that seizures are more commonly experienced around their menstrual periods.

A doctor will be able to change or prescribe other medications for a woman to take before she has her menstrual period each month. Often a newly diagnosed epilepsy sufferer may be advised to keep a record of possible triggers a journal.Types of Seizures; Types of Epilepsy Syndromes; Triggers of Seizures; Diagnosis; The difference between types of seizures is in how and where they begin in the brain.

Learn. Types of Seizures. Who Gets Epilepsy? What Causes a Seizure? What Are the Risk Factors? Is Epilepsy Inherited? Status epilepticus, or epilepsy, is a neurological disorder that causes dogs to have sudden, uncontrolled and recurring seizures.

These physical attacks can come with or without a loss of consciousness. Dog seizures can be caused by trauma, exposure to toxins, brain tumors, genetic abnormalities. One type of epilepsy runs in families and causes seizures during sleep, for instance.

Another such cause of focal seizures is tuberous sclerosis, a rare genetic disease that causes benign tumors to grow in multiple organs of the body, such as the brain, lungs, and heart, and triggers seizures.

Non-epileptic seizures may physically appear like other types of seizures. The differentiating factor is that the electrical activity in the brain is normal. The differentiating factor is that the. Head trauma as a result of a car accident or other traumatic injury can cause epilepsy.

Brain conditions. Brain conditions that cause damage to the brain, such as brain tumors or strokes, can cause epilepsy. Stroke is a leading cause of epilepsy in adults older than age Infectious diseases.

A type of generalized seizure involving sudden loss of muscle tone, which is what causes the person to go limp. Grand Mal Seizure: Also known as a generalized tonic clonic seizure that can last a short period of time, but cause injury to a person.
