Epilepsy & Seizure Disorders

Understanding Epilepsy & Seizure Disorders

Epilepsy is a chronic neurological condition characterized by recurrent, unprovoked seizures. A seizure is a sudden burst of abnormal electrical activity in the brain that temporarily affects how the brain works, leading to changes in awareness, behavior, movements, or sensations.

Epilepsy affects people of all ages and backgrounds. With proper diagnosis and treatment, the majority of people with epilepsy can achieve good seizure control and lead productive lives.

Types of Seizures

Focal (Partial) Seizures

These seizures originate in a specific area of the brain:

• Focal aware seizures — consciousness is preserved; may experience unusual sensations, involuntary movements, or emotional changes
• Focal impaired awareness seizures — consciousness is affected; may involve staring, confusion, repetitive movements (automatisms)
• Focal to bilateral tonic-clonic seizures — starts focally and then spreads to involve both sides of the brain

Generalized Seizures

These seizures involve both hemispheres of the brain from the onset:

• Tonic-clonic (grand mal) seizures — stiffening followed by rhythmic jerking of the body, with loss of consciousness
• Absence seizures — brief episodes of staring and unresponsiveness, common in children
• Myoclonic seizures — sudden, brief jerks of muscles
• Atonic seizures — sudden loss of muscle tone causing falls
• Tonic seizures — sudden stiffening of muscles

Common Causes of Epilepsy

• Genetic factors — family history, inherited epilepsy syndromes
• Structural brain abnormalities — cortical malformations, hippocampal sclerosis
• Brain injury — head trauma, birth injuries
• Infections — meningitis, encephalitis, neurocysticercosis
• Stroke and vascular malformations
• Brain tumors
• Metabolic disorders
• Unknown cause (idiopathic) — in many cases, no specific cause is identified

Diagnostic Approach

Dr. Chetan Padghan follows a systematic approach to epilepsy diagnosis:

Clinical Evaluation

• Detailed seizure history including eyewitness accounts
• Developmental and family history assessment
• Comprehensive neurological examination
• Identification of seizure triggers and patterns

Investigations

• Electroencephalography (EEG) — records brain electrical activity to identify abnormal patterns; may include routine, sleep-deprived, or prolonged EEG monitoring
• Brain MRI (epilepsy protocol) — high-resolution imaging to detect structural abnormalities
• Blood investigations — metabolic panel, genetic testing when appropriate
• Video-EEG monitoring — for complex cases requiring seizure characterization

Treatment Approach

Anti-Seizure Medications (ASMs)

• Selection based on seizure type, epilepsy syndrome, patient age, and comorbidities
• Starting with a single medication (monotherapy) at the lowest effective dose
• Careful dose optimization to maximize seizure control while minimizing side effects
• Regular monitoring of drug levels and side effects

Medication Optimization

• If first medication is ineffective, systematic trial of alternative monotherapy
• Rational polytherapy when monotherapy fails — combining medications with different mechanisms
• Regular review of medication efficacy and tolerability
• Planning for medication withdrawal when appropriate (after prolonged seizure freedom)

Lifestyle Management

• Identification and avoidance of seizure triggers (sleep deprivation, stress, alcohol, flashing lights)
• Sleep hygiene counseling
• Guidance on driving, swimming, and occupational safety
• Reproductive health counseling for women with epilepsy

Advanced Treatment Options

• Pre-surgical evaluation referral for drug-resistant epilepsy
• Consideration of vagus nerve stimulation (VNS)
• Ketogenic diet evaluation for refractory cases
• Referral to comprehensive epilepsy centers when needed

Special Populations

Epilepsy in Children

• Age-specific epilepsy syndromes and their management
• Febrile seizures — evaluation and parent counseling
• Impact on development and learning — school guidance
• Transition planning from pediatric to adult care

Epilepsy in Women

• Contraception and anti-seizure medication interactions
• Pre-conception counseling and folic acid supplementation
• Pregnancy management — medication adjustments and monitoring
• Breastfeeding guidance

Epilepsy in the Elderly

• New-onset epilepsy in older adults — often related to stroke or neurodegeneration
• Medication selection considering polypharmacy and organ function
• Fall risk assessment and prevention

Living with Epilepsy

• Understanding your condition and treatment plan
• Maintaining a seizure diary
• Knowing first aid for seizures
• Addressing stigma and psychological well-being
• Support groups and patient education resources
