Understanding Paroxysmal Dyskinesia in Labradors

Paroxysmal dyskinesia in Labradors is a neurological disorder that affects the motor control systems of the brain. It's a rare condition, but it's essential to understand what causes it and how it affects our beloved Labradors.

The most common type of paroxysmal dyskinesia in Labradors is called idiopathic paroxysmal dystonia, which means the cause is unknown. This type of dyskinesia is characterized by sudden, severe muscle contractions that can cause our furry friends to stiffen, tremble, or even fall.

Labradors with paroxysmal dyskinesia can experience episodes at any time, but they often occur during periods of excitement, stress, or physical activity. These episodes can be triggered by various stimuli, making it challenging for owners to predict when they will happen.

Symptoms of paroxysmal dyskinesia in Labradors can vary in severity and frequency, but they often include sudden muscle contractions, tremors, and loss of coordination.

Most cases of PD in Labradors don't respond to medication, including anti-epileptic medication.

We usually only advise trying treatment if the frequency of the episodes of PD is reaching one, or more than one, episode a week and if the animal's quality of life seems particularly affected.

Anecdotally, Keppra (Levetiracetam) has helped some affected Labradors, but this is not a guaranteed solution.

The signs of paroxysmal dyskinesias can be quite distressing for both dogs and their owners. Affected dogs often display 'cramping' or 'spasm' of the limbs, which is characterized by an increase in muscle tone and abnormal postures.

The hind limbs are often affected more severely than the fore limbs. This can cause dogs to be severely incapacitated during an episode, making it difficult for them to move voluntarily.

During an episode, dogs may appear distressed and unable to walk, but some may still try to move despite the spasm. Episodes can be triggered by excitement or exercise in some cases.

The duration of episodes can vary greatly, ranging from seconds to hours, with the onset and resolution of symptoms being abrupt.

Diagnosing paroxysmal dyskinesia (PD) is a challenging process that requires a detailed history and physical examination.

A detailed history is crucial to precisely characterise the episodes, which may involve reviewing videos of the episodes.

Conducting a physical and neurological examination is also necessary to assess the animal's overall health and neurological status.

The most important differential diagnosis for PD is focal seizures activity, which can cause similar muscle movements.

If the animal shows convincing signs of PD, is neurological normal, and has remained neurological normal in between the episodes for a prolonged time, further diagnostics may not be performed.

However, if this does not apply to the patient, an MRI scan of the brain may be performed to exclude structural disease of the brain, possibly along with a cerebrospinal fluid (CSF) analysis.

Treating PD can be a challenge, especially since most cases don't respond to medication, including anti-epileptic medication.

In fact, the large majority of PDs don't respond to these types of medications.

Cavalier King Charles Spaniels, on the other hand, often respond well to Acetazolamide.

Border Terriers may also benefit from an exclusive gluten-free diet.

Episode duration and frequency can vary greatly, even within the same individual.

Some dogs may have many episodes in a short period, followed by long stretches of normalcy.

As dogs age, episodes often become less frequent and shorter in duration.

Most affected dogs don't require medication and can live a normal life between episodes, which are not life-threatening.

However, if episodes become too frequent, one or more per week, medication may be considered to improve the animal's quality of life.

A unique perspective: Labradors Good Apartment Dogs

The prognosis for dogs with Primary Dysautonomia (PD) is generally very good. Due to a lack of progression and a lack of harm to the patient, a good quality of life should be considered very likely.

It's rare for episodes to be frequent and intense enough to cause an impairment of quality of life, although we've seen cases like that.

A different take: Life with Labradors

Labradors can experience paroxysmal dyskinesias, a condition that affects their movement and coordination.

PD has been reported in Labrador Retrievers in the UK, which is a relatively recent development in the understanding of this condition.

The symptoms of PD in Labradors can vary, but they often involve sudden and uncontrolled movements.

It's essential to work with a veterinarian to determine the best course of action for your Labrador if you suspect they're experiencing PD.

Labradors are not the only breed to experience PD, as it can occur in any dog, including those with specific breeds such as Cavalier King Charles spaniels and Border terriers.

While PD can be challenging to diagnose, a veterinarian can help identify the condition and develop a treatment plan to manage its symptoms.

PD has also been reported in cats, but these episodes are not as well characterised as those in dogs, so it's essential to focus on the specific needs of your Labrador.
