Why am I having seizures when my MRI is normal at 36?

Hello,

Welcome to icliniq.com.

I have read your query.

It is completely understandable to feel worried after a seizure and abnormal test results. But instead of getting scared, it helps to look at the situation calmly and understand what the findings actually mean.

A single seizure (a sudden, uncontrolled disruption of electrical activity in the brain) does not automatically mean epilepsy. Epilepsy (a chronic neurological disorder characterized by recurrent, unprovoked seizures caused by sudden, excessive electrical discharges in brain cells) is usually diagnosed when someone has two or more unprovoked seizures, meaning they were not triggered by factors like fever, alcohol, or drug withdrawal, or very low blood sugar. Because of this, many people who experience one seizure never develop epilepsy.

However, doctors sometimes start treatment after the first seizure if tests suggest there is a higher chance of another seizure occurring. In your case, the EEG (electroencephalogram) showed abnormal electrical activity in the right temporal lobe, which may increase the likelihood of recurrence. Starting medication in this situation is usually a preventive step to reduce risk.

An EEG (electroencephalogram) measures the electrical activity of the brain. Your result showed irritability or “spikes” in the right temporal lobe. This means that the area of the brain is more prone to sudden bursts of electrical activity, which is what triggers seizures.

Your MRI (magnetic resonance imaging) scan, on the other hand, looks at the brain’s structure. Since your MRI was normal, it means there is no tumor, scar tissue, or structural abnormality in the brain. That is reassuring. In simple terms, the brain structure appears normal, but the electrical signaling in one region may occasionally misfire.

Mood changes while taking Levetiracetam are fairly common. Some people experience irritability, anxiety, low mood, or emotional sensitivity. Not everyone develops these side effects, but doctors are aware of them and can adjust treatment if needed.

If you are noticing mood changes, it’s important to inform your doctor as soon as possible. They may adjust the dose or consider switching to another anti-seizure medication such as Lamotrigine or Oxcarbazepine, which sometimes have fewer mood-related effects. At the same time, it is important not to stop your medication on your own, because sudden discontinuation can trigger another seizure.

Regarding whether you will need medication forever, the answer is not necessarily. If this remains a single seizure and you stay seizure-free for about two years, your doctor may consider gradually tapering the medication. If additional seizures occur or EEG findings continue to suggest a higher risk, longer-term treatment may be recommended. Many people successfully manage seizures with medication and lifestyle adjustments.

It may also help to understand how seizures occur. The brain works through a network of electrical signals traveling between nerve cells. During a seizure, a group of brain cells suddenly fires too many electrical signals at once, like a brief electrical short circuit.

Depending on the brain region involved, this can cause symptoms such as staring spells, shaking movements, loss of awareness, or unusual sensations or smells. Because your EEG changes are in the temporal lobe, seizures from this area may affect memory, emotions, awareness, or speech.

Until your doctor advises otherwise, a few precautions can help reduce risk. Avoid driving until you are medically cleared, since many places require a seizure-free period before driving again. Limit or avoid alcohol because it can lower the seizure threshold and interfere with medication. Prioritize good sleep, since sleep deprivation is a common trigger. Managing stress and taking medication consistently at the same time every day are also important.

Some additional factors that can increase seizure risk include dehydration, illness or fever, hormonal changes in some women, and occasionally flashing lights, although light-triggered seizures are uncommon in adults.

The reassuring part of your results is that your MRI is normal, which means there is no structural brain problem. The current focus is simply on reducing the chance of another seizure and finding a treatment plan that works well for you.

I hope this answers your query.
