Basics and possible causes
Epileptiform seizures in dogs can be attributed to a variety of causes. Fundamentally, they are the result of a malfunction of neuronal activity in the brain. This malfunction can be idiopathic, meaning it occurs without a recognizable cause, or it can be symptomatic, meaning it is the result of another disease or trauma.
Idiopathic epilepsy is the most common form of seizures in dogs and often affects young to middle-aged animals. This form of epilepsy is often considered to be genetic, with certain breeds such as the German Shepherd, Beagle, and Labrador Retriever being more susceptible.
Symptomatic seizures can be triggered by a variety of factors, including infections (such as distemper or toxoplasmosis), metabolic disorders (such as hypoglycemia or liver disease), poisoning (by substances such as chocolate or certain plants), or structural abnormalities in the brain (such as tumors or hydrocephalus).
In addition, environmental factors such as stress or sudden changes in a dog’s routine can also act as triggers for seizures. Age also plays a role, as older dogs are more likely to suffer from seizures due to tumors or degenerative diseases.
Typical accompanying symptoms
- Muscle spasms: Sudden and uncontrollable muscle movements that can occur in the form of twitching or seizures.
- Loss of consciousness: The dog may lose consciousness during a seizure, which can manifest as a fixed gaze or complete absence.
- Salivation: Excessive drooling or foaming from the mouth may occur during a seizure.
- Behavioral changes: Before or after a seizure, the dog may exhibit unusual behavior, such as disorientation, confusion, or increased clinginess or attachment.
- Urination or defecation: Incontinence can occur during a seizure, meaning that the dog uncontrollably urinates or defecates.
- Panting or Shortness of breath: Some dogs exhibit noticeable breathing patterns during a seizure, including excessive panting or shortness of breath.
When to visit the vet?
It is important for pet owners to consult a veterinarian immediately at the first signs of a seizure. Even if the seizure stops on its own, a veterinary examination is necessary to determine the underlying cause and take appropriate measures.
A visit to the doctor is particularly urgent if seizures last longer than five minutes or recur at short intervals, as this may be a sign of a life-threatening condition called status epilepticus.
If the dog does not fully regain consciousness after a seizure or shows other neurological symptoms, a veterinarian should also be consulted immediately.
Even if the seizures only occur occasionally, it is advisable to seek veterinary advice to avoid long-term damage and improve the dog's quality of life.
Symptom recognition for animal owners and veterinary diagnostic procedures
The recognition of epileptiform seizures by the pet owner can be challenging, as the symptoms can be varied and sometimes subtle. It is helpful to document the dog’s behavior during a seizure, ideally through video recordings, to show this to the veterinarian.
The veterinarian will conduct a thorough medical history and may also order neurological examinations and blood tests to rule out metabolic disorders or infections. Imaging procedures such as MRI or CT may be necessary to identify structural abnormalities in the brain.
In some cases, an EEG (electroencephalogram) can also be performed to monitor the electrical activity in the brain. This helps to determine the type of seizures more precisely and to develop an appropriate treatment strategy.
Comprehensive diagnostics are crucial in order to differentiate between idiopathic and symptomatic epilepsy and to be able to take targeted therapeutic measures.
What can pet owners do and professional therapy options
During a seizure, the pet owner should remain calm and protect the dog from injury by removing dangerous objects from the environment. It is important not to hold the dog during the seizure or try to put anything in its mouth, as this can lead to injury.
After the seizure, the dog should be monitored in a quiet, safe room until it has fully recovered. It can be helpful to provide him with soft blankets or pillows to provide comfort.
In the long term, drug treatment prescribed by the veterinarian may be necessary to reduce the frequency and severity of the seizures. It is important to administer the prescribed medication exactly as directed and to attend regular veterinary check-ups.
In addition, adjustments to the dog’s lifestyle, such as a low-stress environment or special diets, can have a supportive effect. The pet owner should always pay attention to changes in the dog’s behavior and consult the veterinarian if there is uncertainty / disorientation.
Outlook on current research
Current research on epileptiform seizures in dogs focuses on genetic factors and possible triggers, as well as the development of new treatment methods. A significant advance in genetic research is the identification of specific genes that are associated with an increased susceptibility to seizures in certain dog breeds. These studies aim to develop genetic tests that could enable early diagnosis and intervention.
Another branch of research is investigating the role of environmental factors and lifestyle as potential triggers for epileptiform seizures. Scientists are analyzing how stress, diet, and physical activity affect the frequency and severity of seizures. Initial results suggest that a low-stress environment and a specially adapted diet could reduce the seizure frequency.
In parallel, intensive research is being conducted into the development of new drugs and therapeutic approaches. Some studies are investigating the use of cannabinoids and their effectiveness in controlling seizures. Other research focuses on innovative approaches such as gene therapy to directly address the underlying genetic causes. These approaches are still in the early stages but show promising results in preclinical studies.
In addition to drug treatment, alternative therapies such as acupuncture and physiotherapy measures are increasingly being used in veterinary medicine. These methods are being investigated to see if they can improve the quality of life of dogs with epileptiform seizures as complementary therapies. Earlier reports suggest that such approaches may reduce seizure frequency and improve overall well-being in some dogs.
Research into epileptiform seizures in dogs is a dynamic field that benefits from interdisciplinary approaches. By combining genetics, pharmacology, and alternative therapies, scientists hope to develop more comprehensive and effective treatment protocols that are individually tailored to the needs of affected dogs.
