HelgaDemény

I diagnose and treat epilepsy and other neurological diseases in dogs and cats. Veterinary EEG was the subject of my PhD.

Idiopathic epilepsy is not a dramatic diagnosis; managed properly, early and with a bit of luck, the seizures can be well controlled.From her interview with Veterinarul.ro (in Romanian), February 2026

I have worked with more than 500 dogs and cats with epilepsy. In over 350 of them, the seizures are now under control.

What I treat

I learnt EEG on people before I used it on animals.

  1. Early years

    In the countryside near Târgu Mureș

    I grew up surrounded by animals and never saw myself doing anything other than veterinary medicine.

  2. University

    EEG technician in human epileptology

    From my fifth year I recorded EEGs for the patients of Dr. Bogdan Florea, a neurologist and epileptologist. That is where I learnt to read the electrical activity of the brain.

  3. 2015

    DEMED

    I opened my own practice in Cluj-Napoca, dedicated exclusively to veterinary neurology.

  4. 2017

    Hanover

    After graduating from USAMV Cluj-Napoca, I spent three months in the neurology department of the University of Veterinary Medicine Hanover, in the team of Prof. Dr. Andrea Tipold.

  5. 2021

    Leipzig

    A placement in the neurology department of Leipzig University, in the team of Prof. Dr. Thomas Flegel, with whom I later published a study on non-convulsive seizures.

  6. 2022

    The PhD

    A thesis on the applications of electroencephalography in the diagnosis of canine epileptic seizures and epileptic syndromes, graded Excellent.

  7. Today

    Cluj-Napoca

    I had the chance to work abroad and chose to stay at home. I earned the ESAVS certificate in veterinary neurology, and I see dogs and cats from Cluj and from further afield.

What the EEG sees that the eye cannot.

An electroencephalogram records the electrical activity of the brain. It shows what kind of seizures an animal is having, and that can change the treatment.

At my practice in Cluj I have recorded EEGs on dogs, cats and a lion cub with epilepsy. The principles are the same for every one of them: a careful history, a full neurological examination and a recording made at the right moment.

What owners say

Three of the Google reviews left for my practice, DEMED.

“Linda was having more and more epileptic seizures, going from one a month to 3-4 a month [...]. Linda has now gone 7 weeks without a single seizure on the new treatment. We will keep going to the doctor, even though we are not from Cluj.”
Vali C.Google, dog with epilepsy
“I brought my kitten to Dr. Helga at a point when I really had no hope left [...]. After just 30 minutes of examination, she gave us a clear diagnosis. Today my kitten is full of life again: running, jumping, playing.”
Raul C.Google, kitten paralysed in the back legs
“After several consultations with different vets and no clear diagnosis, I came here with my cat. The way she explains every step of the treatment inspires trust and a sense of security.”
Alexandra C.Google, cat with neurological FIP

Epilepsy · 10 minEpilepsy in dogsEpilepsy in dogs is a brain disorder that causes repeated epileptic seizures with no trigger outside the brain. A dog is considered to have epilepsy after at least two unprovoked seizures more than 24 hours apart. In most dogs it cannot be cured, but with the right diagnosis and carefully monitored treatment the seizures can be controlled and the dog can have a good life.Living with epilepsy · 5 minWhat to do when your dog or cat has an epileptic seizureDuring a seizure, stay calm, move away anything your pet could hit, do not put your hand or any object in its mouth, time the seizure and, if you can, film it. Once a seizure has started, the owner cannot stop it, and most end on their own within 1-2 minutes. If it lasts longer than 5 minutes, or seizures follow one another without recovery, go straight to the nearest emergency vet clinic that is open now.Epilepsy · 6 minSeizure or fainting?Fainting (syncope) is usually brief, lasting a few seconds, with a floppy body and a quick recovery, and no confusion afterwards. A generalised epileptic seizure usually involves a stiff or jerking body, can last 1-3 minutes and is followed by a period of confusion. The difference is confirmed at the consultation, and a video of the episode helps more than anything else.Neurology · 9 minSlipped disc in dogsA slipped disc happens when material from one of the discs between the vertebrae presses on the spinal cord. The signs range from back or neck pain to paralysis of the legs, and the outlook depends mainly on how severe the injury is and how quickly the dog is assessed. If your dog suddenly cannot walk, go straight to the nearest emergency vet clinic that is open now.Neurology · 6 minVestibular syndrome in dogsVestibular syndrome is a sudden loss of balance: the dog holds its head tilted, its eyes flick rhythmically, it falls to one side or walks in circles, and it may feel sick. In older dogs the most common cause is the idiopathic form, meaning no cause is found, which usually improves within a few days and resolves in 2-4 weeks. The same signs can, however, come from the ear or the brain, which is why your dog needs to be examined.Neurology · 6 minWhy is my dog shaking?Most often a dog shakes because it is cold, frightened, excited or in pain, and the shaking stops once the cause goes away. Shaking that starts suddenly and affects the whole body, especially with drooling, vomiting, dilated pupils or an unsteady gait, may be poisoning and is an emergency. Tremors that go on for days with no obvious cause need a vet's examination, because they may be a treatable neurological syndrome.

Frequently asked questions

About the consultation, EEG and treatment.

All questions
How do I book an appointment?

Fill in the appointment form, or send a WhatsApp message to 0745 145 033 or an e-mail to helga@demed.ro. For non-urgent cases, please write rather than call. You will get a call the day before the consultation to confirm.

What is an EEG?

An electroencephalogram (EEG) records the electrical activity of the cerebral cortex. It can pick up abnormal discharges between seizures, which support a diagnosis of epilepsy and help to identify the type of seizures. More on the veterinary EEG page.

What is epilepsy?

Epilepsy is a brain disease that causes epileptic seizures to happen repeatedly. The diagnosis requires at least two unprovoked seizures at least 24 hours apart. When no cause is found in the brain or elsewhere in the body, it is called idiopathic epilepsy. More in the guide to epilepsy in dogs.

I live in another town. How do I start?

Send the videos of the episodes and any test results in advance, by WhatsApp to 0745 145 033 or by e-mail to helga@demed.ro, then book the consultation through the form. That way the information is read before the visit and tests already done are not repeated. More on the page for patients from outside Cluj.
