Epilepsy is one of the most common neurological disorders, affecting millions of people worldwide. It can start at any age and has various causes, ranging from genetic factors to brain injuries and infections. While some people experience only occasional seizures, others may have frequent episodes that impact their daily lives. Advances in medicine have significantly improved the management of epilepsy, helping individuals lead normal, fulfilling lives.
Understanding epilepsy is crucial not only for those diagnosed but also for caregivers and society. Let’s take a closer look at what epilepsy is and how it affects people. We will explore the epilepsy symptoms, types of epilepsy, epilepsy treatment options, and epilepsy triggers in the blog to understand the condition better.
Synopsis
What is Epilepsy?
Epilepsy is a chronic brain condition that causes seizures due to sudden electrical disturbances in the brain. These seizures can range from mild, where a person experiences brief confusion. In severe cases, a person diagnosed with epilepsy can lose consciousness and experience uncontrollable body movements.
Who Can Get Epilepsy?
Epilepsy can affect people of all ages, but it is more common in infants and children due to their developing neural structures. Adults and the elderly, especially due to strokes, brain infections, or tumours.
Is Epilepsy Inherited?
Some forms of epilepsy have a genetic link, meaning they can run in families. However, most cases are caused by brain injuries, infections, autoimmune conditions, or metabolic disorders.
What Causes Epilepsy?
Epilepsy occurs due to abnormal electrical activity in the brain, but the underlying reasons for this disruption can vary widely. Some individuals develop epilepsy due to structural brain abnormalities, while others may have a genetic predisposition. In some cases, no clear cause is identified, making it a condition with diverse origins. Let’s understand the factors from the below list:
Genetic Factors: Some people inherit mutations in genes that affect brain activity, making them more likely to develop epilepsy.
-
Brain Injuries: Head trauma from accidents, falls, or sports injuries can damage the brain and cause seizures.
-
Brain Tumours and Stroke: Structural issues in the brain, such as tumours, strokes, or aneurysms, can trigger epilepsy, especially in older adults.
-
Infections: Brain infections like meningitis, encephalitis, or neurocysticercosis can lead to epilepsy.
-
Autoimmune Disorders: Certain autoimmune conditions can cause brain inflammation, leading to seizures.
-
Developmental Disorders: Conditions like autism and cerebral palsy are associated with epilepsy.
-
Metabolic Imbalances: Issues like low blood sugar, sodium imbalances, or vitamin deficiencies can also contribute to epilepsy.
Types of Epilepsy
Epilepsy is classified based on the type of seizures a person experiences.
Generalised Epilepsy: Seizures affect both sides of the brain. Examples include:
-
Tonic-clonic seizures: Sudden loss of consciousness, stiffening, and jerking movements.
-
Absence seizures: Brief staring episodes, mostly in children.
-
Focal Epilepsy: Seizures originate from a specific part of the brain and may or may not affect consciousness.
-
Unknown-Onset Epilepsy: When the origin of seizures is unclear, it is classified as unknown-onset epilepsy.
What are Epilepsy Triggers?
While epilepsy is a neurological condition, seizures are not always random. Certain factors, known as triggers, can increase the likelihood of a seizure in people with epilepsy. These triggers vary from person to person, and identifying them can help manage the conditions better.
Common epilepsy triggers include:
-
Lack of sleep - Sleep deprivation can disturb brain activity, making seizures more likely.
-
Stress and anxiety - Emotional stress can trigger seizures in some individuals.
-
Flashing lights - Bright or flickering lights may cause seizures, especially in photosensitive epilepsy.
-
Alcohol or drug use - These substances can affect brain function and lower the seizure threshold.
-
Hormonal changes in women - Menstrual cycles or hormonal fluctuations can sometimes increase seizure frequency.
-
High fever or infections - Illnesses that cause high body temperature can trigger seizures, especially in children.
-
Skipping medications - Missing epilepsy medication doses can lead to breakthrough seizures.
-
Low blood sugar levels - Hypoglycaemia can affect brain function, increasing seizure risk.
Is Epilepsy Curable?
Epilepsy is a manageable condition, but whether it can be completely cured or not depends on the underlying cause. A seizure is a manifestation of a disturbed electrical circuit formed by certain neurons. Identifying the underlying cause is the most important step in management. Seizures can be controlled by appropriate anti-seizure medications. Usually, treating underlying conditions, proper adjustment of anti-seizure medication, and slow tapering of medications will give satisfactory results. Certain genetic epileptic disorders, epilepsy with developmental problems or epilepsy associated with other genetic diseases may need long-term treatment with suitable anti-seizure medications.
Epilepsy Treatment Options
In recent years, epilepsy management has seen remarkable progress, improving patient outcomes and reducing complications. With newer treatments and technologies, people with epilepsy now have better options for seizure control and overall well-being.
-
New medications – Modern anti-seizure drugs offer better efficacy with fewer side effects. This makes long-term management easier.
-
Surgical advancements – Epilepsy surgeries for drug-resistant cases have shown higher success rates, providing relief for many patients.
-
Neuromodulation therapies – Treatments like Vagus Nerve Stimulation (VNS) and Deep Brain Stimulation (DBS) help reduce seizure frequency, lowering dependence on medication.
-
Dietary approaches – The ketogenic diet and high-dose pyridoxine (vitamin B6) have proven effective for specific types of epilepsy, particularly in children with genetic mutations.
-
Advanced monitoring – Improvements in EEG technology and wearable seizure detection devices allow for early diagnosis and better seizure tracking, enhancing patient safety.
-
Research and genetic studies – Advances in genetic testing, including whole genome and exome sequencing with next-generation sequencing, have improved diagnosis and personalised treatment approaches.
-
Autoimmune and paraneoplastic encephalitis treatment – Patients with identified antibodies, such as anti-NMDA receptor encephalitis, have shown good seizure control and recovery with targeted immune therapies.
