Every year on March 26, Purple Day is observed worldwide to raise awareness about epilepsy—one of the most common yet widely misunderstood neurological disorders. Despite affecting millions, myths and stigma still surround the condition.
This guide breaks down what epilepsy is, how it’s diagnosed, the different types of seizures, and the treatment options available—while also highlighting why awareness matters.
What Is Epilepsy?
Epilepsy is a long-term neurological condition marked by recurrent, unprovoked seizures. These seizures happen when there’s a sudden surge of abnormal electrical activity in the brain, disrupting normal communication between nerve cells.
Seizures can look very different from person to person. Some may experience brief moments of confusion or staring, while others may have full-body convulsions.
It’s important to note:
A single seizure doesn’t mean epilepsy. The condition is typically diagnosed when a person has two or more unprovoked seizures occurring at least 24 hours apart.
How Is Epilepsy Diagnosed?
Diagnosing epilepsy isn’t always straightforward, as seizures can resemble other conditions like fainting or migraines. Doctors use a combination of tools to confirm the diagnosis:
- Medical history & eyewitness reports: Details of what happened before, during, and after the seizure
- Neurological exams: Assessing reflexes, coordination, and cognitive function
- EEG (Electroencephalogram): Records brain activity to detect abnormal patterns
- Brain imaging (MRI/CT scans): Identifies structural issues like tumors or scarring
- Blood and genetic tests: Helps rule out infections or inherited conditions
In some cases, video-EEG monitoring is used to capture seizures in real time for more accurate analysis.
Types of Seizures
Seizures are broadly divided into two main categories:
1. Focal Seizures (Partial Seizures)
These begin in a specific area of the brain.
- Focal aware seizures: Consciousness remains intact; may involve unusual sensations or limb movements
- Focal impaired awareness seizures: Reduced awareness, often with repetitive actions like lip-smacking or wandering
2. Generalized Seizures
These affect both sides of the brain.
- Absence seizures: Brief staring spells, common in children
- Tonic seizures: Sudden muscle stiffening
- Atonic seizures: Loss of muscle control, leading to falls
- Clonic/Myoclonic seizures: Rhythmic jerking or sudden twitches
- Tonic-clonic seizures: Severe episodes with stiffening, shaking, and loss of consciousness
Identifying the type of seizure is key to choosing the right treatment.
How Common Is Epilepsy?
Epilepsy affects around 50 million people globally, making it one of the most widespread neurological conditions.
- About 5 million new cases are diagnosed each year
- Higher prevalence is seen in low- and middle-income countries due to limited healthcare access and higher risk factors
- In India, epilepsy remains a major public health concern, impacting millions across both urban and rural areas
Is Epilepsy Genetic?
Genetics can play a role—but not always.
Some types of epilepsy are linked to inherited gene mutations, while others occur due to new mutations or external factors like:
- Head injuries
- Infections
- Stroke
Children of parents with epilepsy have a slightly higher risk (2–5%) compared to about 1% in the general population. However, most do not develop the condition.
Treatment Options
While there is no universal cure, epilepsy is highly manageable. In fact, up to 70% of people can live seizure-free with proper treatment.
Common Treatment Approaches:
- Anti-seizure medications (ASMs): First-line treatment, tailored to seizure type and individual needs
- Surgery: Removes or isolates the area of the brain causing seizures (for drug-resistant cases)
- Neurostimulation devices:
- Vagus Nerve Stimulation (VNS)
- Responsive Neurostimulation (RNS)
- Ketogenic diet: High-fat, low-carb diet, especially effective in children
- Lifestyle management: Adequate sleep, stress control, avoiding triggers, and medication adherence
Breaking the Stigma
Beyond medical care, epilepsy requires awareness and empathy.
Stigma often prevents people from seeking help or living confidently. Purple Day is not just about education—it’s about support and inclusion.
Wearing purple symbolizes solidarity with those living with epilepsy and a commitment to ending discrimination.
Final Thoughts
Epilepsy is common, complex, and often misunderstood—but it is manageable.
With early diagnosis, proper treatment, and greater awareness, people with epilepsy can lead full and productive lives. On Purple Day, let’s commit to spreading knowledge, challenging misconceptions, and supporting those affected.
