Epilepsy in Adults: Causes, Triggers, and Treatment Options

What Is Epilepsy?

Epilepsy is a neurological condition characterized by a tendency to have recurrent, unprovoked seizures. A seizure occurs when there is a sudden burst of abnormal electrical activity in the brain, which can temporarily affect movement, sensation, awareness, or behavior, depending on which part of the brain is involved.

It's important to understand that having a single seizure doesn't necessarily mean someone has epilepsy. Epilepsy is generally diagnosed when a person has had two or more unprovoked seizures, or in some cases, a single seizure combined with a high likelihood of recurrence based on brain imaging or other findings.

Types of Seizures

Seizures are broadly categorized based on how and where they start in the brain:

Focal Seizures These begin in one specific area of the brain and may or may not affect consciousness. Symptoms can include unusual sensations, brief confusion, repetitive movements, or localized twitching, depending on the brain region involved.

Generalized Seizures These involve both sides of the brain from the onset and can present in several ways:

• •Tonic-clonic seizures — involving stiffening of the body followed by rhythmic jerking movements, often what people picture when they think of a seizure
• •Absence seizures — brief lapses in awareness, sometimes appearing as staring spells
• •Myoclonic seizures — sudden, brief muscle jerks
• •Atonic seizures — sudden loss of muscle tone, which can cause falls

Some patients experience more than one seizure type, and identifying the specific pattern helps guide diagnosis and treatment.

Common Causes of Adult-Onset Epilepsy

Unlike childhood epilepsy, which is often linked to genetic or developmental factors, adult-onset epilepsy frequently has an identifiable structural or acquired cause:

1. Stroke
Stroke is one of the leading causes of new-onset epilepsy in older adults. Scar tissue or damage from a stroke can create an area of abnormal electrical activity in the brain, sometimes leading to seizures months or even years after the stroke itself.

2. Head Injury
Traumatic brain injury, particularly moderate to severe injuries, can result in seizures developing weeks, months, or years after the initial trauma, as the brain tissue heals with scarring.

3. Brain Tumors
Both benign and malignant brain tumors can trigger seizures by disrupting normal electrical activity in surrounding brain tissue, making new-onset seizures in adults an important reason for thorough brain imaging.

4. Infections of the Brain
Past or current infections affecting the brain or its coverings, such as meningitis or encephalitis, can lead to seizure disorders, sometimes as a long-term consequence even after the infection has resolved.

5. Metabolic and Electrolyte Imbalances
Significant imbalances in blood sugar, sodium, calcium, or other electrolytes can provoke seizures, and in some cases, correcting the underlying imbalance can prevent recurrence.

Common Seizure Triggers

For individuals already diagnosed with epilepsy, certain factors can lower the seizure threshold and provoke breakthrough seizures, even when the underlying condition is otherwise being managed:

• •Missed or inconsistent medication doses — one of the most common and preventable triggers
• •Sleep deprivation, which significantly increases seizure susceptibility
• •Alcohol consumption or withdrawal
• •High stress and anxiety
• •Flashing or flickering lights, in a subset of patients with photosensitive epilepsy
• •Fever or illness, which can lower seizure threshold temporarily

Identifying and managing personal triggers is often an important part of long-term seizure control, alongside medication.

Recognizing a Seizure

• •Sudden stiffening or jerking movements of the body
• •Brief loss of awareness or staring spells that don't respond to voice or touch
• •Sudden falls without an apparent cause
• •Confusion or unusual behavior lasting from seconds to several minutes
• •Loss of bladder or bowel control during the episode
• •A period of confusion, tiredness, or headache following the seizure (postictal state)
• •In focal seizures, unusual sensations, repetitive movements, or brief altered awareness without full loss of consciousness

How Epilepsy Is Diagnosed at Jigyasa Hospital

A thorough evaluation is essential, both to confirm the diagnosis and to identify any underlying, treatable cause. At Jigyasa Hospital, Dr. C.P. Singh's evaluation typically includes:

1. Detailed Clinical History
Understanding exactly what happened before, during, and after the episode — often with input from a witness, since the patient themselves may not recall the event clearly — is one of the most valuable diagnostic tools.

2. Neurological Examination
Assessing overall neurological function to detect any signs pointing toward an underlying structural or systemic cause.

3. Blood Tests
Checking blood sugar, electrolytes, kidney and liver function, and other relevant markers to rule out metabolic causes of seizures.

4. Brain Imaging
CT or MRI scans of the brain help identify structural causes such as prior stroke, tumors, or scarring, particularly important in new-onset adult seizures.

5. Electroencephalogram (EEG)
This test records the brain's electrical activity and can help identify abnormal patterns associated with epilepsy, supporting diagnosis and helping classify seizure type.

6. Referral for Specialized Care
Where a structural cause, complex seizure pattern, or treatment-resistant epilepsy is identified, coordination with specialized neurology care is arranged as part of comprehensive management.

Living with Epilepsy: What Patients Should Know

With appropriate treatment, a large proportion of people with epilepsy achieve good seizure control and are able to lead full, active lives. Success depends heavily on:

• •Consistent medication adherence, even once seizures have stopped
• •Regular follow-up to fine-tune treatment over time
• •Open communication with family and workplace about the condition, where appropriate, to ensure safety and support
• •Awareness of personal triggers and proactive lifestyle adjustments

What to Do If Someone Has a Seizure

• •Stay calm and stay with the person
• •Gently guide them away from anything that could cause injury, such as sharp objects or furniture
• •Do not restrain their movements or put anything in their mouth
• •Turn them onto their side once jerking movements stop, to help keep their airway clear
• •Time the seizure — if it lasts longer than five minutes, or another seizure follows without full recovery in between, seek emergency medical help immediately
• •Stay with them until they are fully alert, as confusion is common immediately afterward
