Epilepsy Overview: Types, Warning Signs and Risk Factors

Epilepsy is a neurological disorder characterised by recurrent, unpredictable seizures that can occur in all age groups. These seizures are caused by abnormal electrical activity in the brain. 

According to the WHO, around 50 million people worldwide have epilepsy, making it one of the most common neurological diseases globally. The risk of premature death in people with epilepsy is up to three times higher than in the general population. 

In many parts of the world, there is discrimination and stigma faced by epileptic patients. Thus, epilepsy awareness is essential to combat stigma, promote early recognition and treatment, ensure safety, empower individuals with epilepsy, and enhance the quality of life for those living with the condition. In this article, we will understand what epilepsy is, its causes, symptoms, and management. 

Epilepsy and Its Causes 

Epilepsy is a neurological disorder characterised by recurrent, unprovoked seizures due to sudden, abnormal electrical activity in the brain. The causes of epilepsy can be diverse and often vary among individuals. Genetic factors, brain injuries, tumours, infections, developmental disorders, strokes, congenital conditions, metabolic disorders, and substance abuse are all potential contributors. Structural abnormalities in the brain, disruptions in brain development, and metabolic imbalances may predispose individuals to epilepsy. Additionally, febrile seizures in childhood can sometimes lead to epilepsy later in life. Identifying the exact cause of epilepsy can be challenging, and in many cases, it remains unknown.

Types and Risk Factors 

Epilepsy encompasses various types of seizures, including generalised seizures (affecting both sides of the brain) and partial seizures (originating in specific areas). Risk factors for epilepsy include a family history of seizures, head injuries, brain conditions like tumours or infections, developmental disorders, age (particularly young children and older adults), seizure triggered due to lack of sleep or stress, prenatal factors, birth-related brain injuries, alcohol or drug abuse, and other medical conditions like Alzheimer's disease or stroke. 

Warning signs 

Symptoms of epilepsy can vary widely depending on the type of seizure and the individual. The most common symptom is a seizure itself, which can present in different forms, including convulsions, sudden jerking movements, or loss of consciousness. Some individuals may experience warning sensations or symptoms before a seizure, such as visual disturbances, unusual smells, or strange sensations. Other warning signs may include unexplained staring spells, repetitive movements like lip-smacking, confusion, memory lapses, tingling sensations, or sudden changes in mood or behaviour. Injuries sustained during seizures, such as bruises and tongue biting, may also be symptoms. It's essential to recognise these symptoms and seek medical evaluation for proper diagnosis and management of epilepsy.

Treatment and Management of Epilepsy 

The treatment and management of epilepsy aim to control seizures, minimise side effects, and improve overall quality of life. Its management typically involves a multifaceted approach tailored to each individual's specific needs and circumstances. Medications are commonly prescribed to control seizures. In cases where medications fail, surgical removal of the seizure focus may be an option. 

Apart from medication, adopting a healthy lifestyle can help manage epilepsy. This may include getting enough sleep, reducing stress, avoiding alcohol and recreational drugs, and maintaining a balanced diet. Some individuals may benefit from identifying and avoiding seizure triggers, such as flashing lights or specific foods. Apart from these, behavioural support, which includes counselling and support groups, provides emotional and practical assistance for coping with epilepsy.

Outlook

Epilepsy is a manageable condition with the right diagnosis, treatment, and lifestyle adjustments. By spreading awareness and breaking the stigma, we can ensure a better quality of life for those living with epilepsy. Early recognition, proper medical care, and emotional support play crucial roles in empowering individuals to lead fulfilling lives despite the challenges of this condition.
