Epilepsy Types and Causes

Epilepsy is one of the most common brain conditions in Indonesia. It affects approximately 0.5% to 0.9% of the population, which translates to more than a million people nationwide.

Epilepsy happens when the brain’s electrical signals become disrupted, causing repeated seizures. These seizures can be frightening and confusing, both for patients and their families.

The good news is that epilepsy can be managed with the right care. Bali International Hospital offers advanced treatment, state-of-the-art diagnostic tools, and expert support to help patients lead safer and more comfortable lives.

What is Epilepsy?

Epilepsy is a long-term neurological disorder that causes sudden bursts of abnormal electrical activity in the brain. These bursts can lead to seizures, which may look different from person to person.

Some people experience brief moments of staring, while others may collapse or lose control of their movements. Anyone, children, adults, or older people, can develop epilepsy.

In developing countries like Indonesia, the number of people with epilepsy is growing. This is often due to infections, head injuries, and challenges in accessing early medical care.

With better awareness and improved medical services, more people can now receive proper diagnosis and treatment.

Types of Epilepsy

Epilepsy is mainly grouped into two types: generalized epilepsy and focal epilepsy. These categories describe where seizures start in the brain.

Generalized Epilepsy

Generalized epilepsy affects both sides of the brain at the same time. Because the whole brain is involved, seizures can affect awareness, muscle control, and movement.

Common seizure types include:

• Absence seizures: Short pauses or staring spells.
• Myoclonic seizures: Quick, sudden muscle jerks.
• Tonic seizures: Sudden muscle stiffness in the arms, legs, or back.
• Clonic seizures: Repeated jerking movements.
• Tonic-clonic seizures: A combination of stiffening and jerking, often the most recognizable type.
• Atonic seizures: Sudden loss of muscle strength, sometimes causing falls.

These seizures can affect school, work, and daily activities. But with proper medical treatment, many people manage generalized epilepsy well.

Focal Epilepsy

Focal epilepsy, also called partial epilepsy, begins in only one area of the brain. This is the most common type in Indonesia, making up about 60% of cases.

There are two kinds of focal seizures:

• Focal aware seizures: The person stays conscious and aware.
• Focal impaired awareness seizures: Awareness becomes reduced or lost.

Symptoms vary depending on which part of the brain is affected. They can include:

• Motor symptoms: Jerking, twitching, or stiff movements.
• Non-motor symptoms: Changes in feelings, smells, emotions, or sudden confusion.

Because focal epilepsy is so common, early diagnosis and proper treatment are important to prevent seizures from becoming more frequent or severe.

Causes of Epilepsy

Epilepsy has many possible causes. In some people, the cause is clear, while in others, it remains unknown.

Genetic Factors

Some types of epilepsy run in families. This does not mean parents directly pass epilepsy to their children, but certain genes may make a person more likely to develop seizures.

Structural Causes

Problems with the structure of the brain can trigger epilepsy. In Indonesia, a common cause is Mesial Temporal Sclerosis (MTS), which is a type of scarring in the brain’s temporal lobe.

This scarring disrupts normal activity and often leads to repeated seizures.

Infections and Head Injuries

Infections like meningitis, encephalitis, and parasitic infections are still common causes of epilepsy in Indonesia. Serious head injuries, from traffic accidents, falls, or workplace incidents, also increase the risk of developing epilepsy.

Socioeconomic Factors

Access to healthcare, good nutrition, and early medical attention play a big role in epilepsy prevention and treatment. In areas with limited medical facilities, many people experience delays in diagnosis or cannot access the medications they need.

Social stigma also makes some families afraid to seek help.

Prevalence and Public Health Implications

Experts estimate that 1.2 to 2 million people in Indonesia are living with epilepsy. Many of them may not yet be diagnosed.

This reflects global trends showing that epilepsy is more common in developing countries due to infections, accidents, and limited access to specialists. Indonesia faces several challenges, including:

• Late diagnosis
• Limited access to neurologists and advanced medical tests
• Stigma and misunderstanding about epilepsy
• Unequal access to long-term medication

By increasing awareness and improving access to care, Indonesia can help more people live safely and confidently with epilepsy.

Frequently Asked Questions

What are the five main groups of epilepsy types?

Some medical sources classify epilepsy into five groups:

• Focal
• Generalized
• Combined generalized and focal
• Unknown epilepsy
• Special epilepsy syndromes

What are the 4 stages of epilepsy?

A seizure may involve these four stages:

• Prodrome (early warning signs)
• Aura (initial symptoms before the seizure)
• Ictal (the seizure itself)
• Postictal (recovery phase)

Are there 40 different types of epilepsy?

Yes. When all seizure types and epilepsy syndromes are included, there are more than 40 types recognized by experts.
