After a first-observed convulsion causing loss of consciousness with falling and shaking, it is natural to wonder, will the person have another convulsion? If so, when? Why did it happen? Is this epilepsy or just a seizure? These are questions patients, families and doctors must deal with.

Epilepsy is diagnosed when more than one seizure occurs if the seizure is not a “reactive” seizure. Reactive seizure are caused by some transient medical condition that can disappear such as infections, toxins and drugs, or temporary loss of a body organ function (e.g., liver, kidney, lung, etc.) that then heal and further seizures do not occur. When a second convulsion occurs, even if the first and this second seizure are separated by years, epilepsy is diagnosed. Epilepsy means recurrent seizures.

Epilepsy can be caused by brain injuries, strokes, tumors, infections, degenerative diseases such as Alzheimer’s disease, Multiple Sclerosis, Parkinson’s Disease, inherited conditions, and other diseases. Recognition of genetic causes of epilepsy is rising as science improves to identify abnormal genes. However, epilepsy is not common in families. Causes for approximately 50% of epilepsy cases are never found. Currently, onset of epilepsy is no longer most common in children, rather, it most commonly occurs in those over age 60. This is because we are living longer and we are susceptible to more insults to our brains.

One percent of the world-wide population has epilepsy. Approximately half of all people with epilepsy have their seizures controlled; these people can remain seizure-free if they are on the “best” anti-epilepsy drug (AED) at the “best” dosage for that individual. They must continue this medication as they are not cures. Finding this medication is a trial-and-error process of the patient working with doctors and the AEDs. Another 30% of epilepsy patients will have a seizure every few weeks to months; they have “incomplete” control. The remaining 20% of patients have “uncontrolled” epilepsy; they experience seizures each day or every few days despite taking AEDs. Epilepsy brain surgery is the most effective treatment to decrease or even cure epilepsy for people in whom no AED works. If the brain focus causing the epilepsy can be identified on various tests then attempting its surgical removal is deemed promising for marked improvement in epilepsy control or even cure.

Brain scans (to search for abnormal areas) and electroencephalograms (EEG) may identify a seizure-causing focus. Spinal taps (if infection or other brain conditions are suspected) and blood and urine tests to screen for other conditions also help doctors identify epilepsy causes.

EEGs are normal in half of all people with epilepsy because the test of multiple wires on the scalp is done for just an hour or so and the EEG abnormalities do not always occur during that time. Ambulatory EEGs (the person has EEG wires pasted on the scalp connected to a small recording device on their body as they carry out daily activities over 24 hours) may pick up abnormalities. More sophisticated testing in special labs can be done where EEGs and video cameras are used to capture abnormalities as the monitored-person lies in bed.

Pseudoseizures-involuntary, psychological, causes of “seizures”-are not rare and can complicate epilepsy diagnosis and treatment. See my past blogs on this subject at blog #10 (March 23, 2011); Blog#49 (August 27, 2014); Blog #99 (October 26, 2018).

The diagnosis of epilepsy depends on the clinical history of searching for, and characterizing,  “spells” patients complain of along with the above testing which commonly are all normal. Ultimately, clinical judgment and the experience of your physician are crucial.

  1. Hello my son is 8 years old and had is first seizure at 2 years he was diagnosed with generalized epilepsy at 5 years old has been on medication since until doctor got him off and on he broke out on a seizure lasting almost 10 minutes he was put back on medication and the meds even increased ever since were back to his moody ness, tantrums, waking up every morning struggling and at night when asleep his body is constantly twitching mostly from his upper body, he had another big seizure and were still at it with all these moods. we tried different meds nothing was really working. I never stopped battling it, I’m open and supportive when looking at alternative and procedures. I saw someone comment on a website. Her daughter had seizure and she used a herbal medicine for her daughter seizure and she was seizure free. I’m glad that it was possible. I was ready to try anything that we help my son, i had a conversation with the Dr . I decided try the herbal medicine, I purchased the medicine. my son started taking the medicine. I was shocked to see my son improve, he stop having seizures. his more active and no more seizure. I’m so happy to see my son seizure free. Do as much google research as you can and do not give up on trying. If there is improvement continue, if there is no improvement stop and try something else Everyone is different. thank God my son is seizure free. you can email him on
