Understanding Seizures: Types, Symptoms, and What to Do in India

What Exactly is a Seizure?

Imagine your brain as a bustling city, with billions of nerve cells, or neurons, constantly sending messages to each other using electrical signals. It's an incredibly organised symphony of communication that keeps everything running smoothly. But sometimes, this symphony can hit a jarring note. A seizure happens when there's a sudden, uncontrolled surge of electrical activity in a part of the brain. It’s like a sudden power surge in that city, disrupting the normal flow of information and causing temporary, involuntary changes in behaviour, movement, or sensation. It’s important to understand that not all seizures mean you have epilepsy, a condition defined by recurrent seizures. Many people experience just one seizure in their lifetime, and it might be triggered by a specific event. Recognizing the different types of seizures and their symptoms is key to knowing how to help someone experiencing one, and when to seek professional medical attention.

How Are Seizures Classified?

Doctors classify seizures based on where they start in the brain and whether they affect consciousness. This helps in understanding the underlying cause and choosing the best treatment. The two main categories are:

• Focal Seizures: These begin in one specific area or network of cells on one side of the brain. They used to be called partial seizures.
• Generalized Seizures: These involve both sides of the brain from the outset. Sometimes, a focal seizure can spread to involve both sides, becoming a generalized seizure.

Understanding Focal Seizures

Focal seizures occur when abnormal electrical activity starts in just one hemisphere of the brain. They are quite common, with about 60% of people experiencing epilepsy having focal seizures. These can be further divided based on whether awareness is affected:

1. Focal Aware Seizures (Previously Focal Simple Seizures)

During these seizures, you remain fully conscious and aware of yourself and your surroundings. You know what’s happening. Symptoms can vary widely and might include:

• Sudden, unusual emotions like fear or joy.
• Strange sensations like tingling, numbness, or a metallic taste.
• Unusual smells or sights.
• Involuntary jerking or twitching of a limb or part of the body.
• Changes in how you hear or see.
• A feeling of déjà vu.

These seizures can be brief, lasting from a few seconds to a couple of minutes.

2. Focal Impaired Awareness Seizures (Previously Focal Complex or Partial Complex Seizures)

In this type, your awareness of yourself and your surroundings is partially or completely lost. You might look awake, but you won't remember what happened during the seizure. People often experience automatic behaviours called automatisms, which can seem strange or out of place. These can include:

• Repetitive movements like lip-smacking, chewing, or swallowing.
• Fumbling with clothes.
• Walking or wandering aimlessly.
• Repeating words or phrases.
• Making strange noises.
• Performing dangerous actions, like walking into traffic, without realizing the danger.

These seizures can last anywhere from 30 seconds to 3 minutes. After the seizure, you might feel very tired, confused, or disoriented.

3. Focal to Bilateral Tonic-Clonic Seizures (Previously Secondary Generalized Seizures)

This happens when a focal seizure (either aware or impaired awareness) spreads to involve both sides of the brain. It then becomes a generalized tonic-clonic seizure. This type has two main phases:

• Tonic Phase: This is the first stage, characterized by sudden muscle stiffening throughout the body. People may cry out, lose consciousness, and fall if standing. Other symptoms include:
  • Intense muscle rigidity.
  • Back arching.
  • Possible biting of the tongue or inner cheek.
  This phase typically lasts for about 30 seconds to a minute.
• Clonic Phase: Following the stiffness, the muscles begin to contract and relax rhythmically, causing jerking or shaking movements. This is what people most commonly associate with seizures. Symptoms include:
  • Rhythmic jerking of the arms and legs.
  • Loss of bladder or bowel control.
  • Breathing may become irregular or stop briefly.
  This phase can last from 1 to 3 minutes. After a focal to bilateral tonic-clonic seizure, individuals usually experience a period of deep sleep and confusion, known as the postictal state.

Understanding Generalized Seizures

Generalized seizures affect both sides of the brain from the start. They are not caused by a seizure spreading from one side to the other. There are several types:

1. Tonic-Clonic Seizures (Previously Grand Mal Seizures)

These are the most dramatic and widely recognized type of seizure. They involve the entire body and include the tonic and clonic phases described above. A generalized tonic-clonic seizure can last from 1 to 3 minutes. Following the seizure, the person will likely be tired and confused.

2. Absence Seizures (Previously Petit Mal Seizures)

These are characterized by brief lapses in awareness. They are more common in children but can occur at any age.

• Typical Absence Seizures: These seizures cause sudden symptoms like staring blankly into space. The person might appear to be daydreaming or suddenly stop talking mid-sentence. They are usually very brief, lasting less than 10 seconds. The person has no memory of the event.
• Atypical Absence Seizures: Symptoms develop more slowly and may last longer, typically 20 seconds or more. They can include staring blankly, eye fluttering, and some subtle body movements like hand gestures or lip-smacking. These can also occur multiple times a day.

3. Myoclonic Seizures

These seizures involve sudden, brief muscle jerks or twitches, often affecting the arms, shoulders, or legs. They can feel like a sudden electric shock. These seizures usually last only 1 or 2 seconds and can occur in clusters, sometimes multiple times a day or over several days.

4. Atonic Seizures (Drop Attacks)

These seizures cause a sudden loss of muscle tone, leading to the person becoming limp and often falling to the ground. They are sometimes called
