Myelin Deficiency In Cats: What Should You Know About It?


A fatty substance, which covers the axons, myelin actually serves a significant function for the nerve cells –being an insulator, protecting the nerve from any outside influences, and being a support for sending the process nervous system actions’ cellular transmission. Hence, hypomyelination or an inadequate myelin production in the body, may be distressing for central nervous system. It may even cause some tremors that are most ostensible when the cat’s active. In this article, we will discuss some more interesting myelin deficiency in cats including its causes, symptoms, prognosis, and treatments. Read on to learn more about these!

What is Myelin Deficiency in Cats?

Most of the myelin deficiency are congenital and start manifesting the symptoms in cats lesser than one year old and frequently soon after birth. The conditions may affect the central nervous system and/or the (PNS) peripheral nervous system. In case you have a young cat that’s deferred reflexes, possesses tremors in the trunk, head, and/or limbs, of if the cat’s not able to move or stand, take the cat to the vet immediately. On the other hand, if you have an adult feline, which either suddenly or gradually develops the symptoms, the cat need to see a vet immediately as the myelin of the animal might be deteriorating as a result of acquired condition.

Moreover, myelin is the sheath or lipid membrane, which protects and covers the axons that are the slender projections, which allow neurons, in order to converse with some other cells within the peripheral and central nervous systems.

In addition, the myelin membrane that shelters the axon like an outlet, permitting an electrical information to flow quickly and safely from the neuron to some other cells. If the myelin incorrectly develops, doesn’t develop, or becomes scarce over time, austere neurological dysfunction may result. This kind of dysfunction may cause an animal in having delayed reflexes, possibly seizures, incapacity to move or stand, and tremor.


Even though there are so many different conditions, which may cause myelin insufficiency in cats, utmost are actually hereditary while there might be rare instances of attained myelin deterioration.

Congenital Myelin Disorders

Congenital myelin disorders include dysmyelination and hypomyelination. The conditions might be X linked hereditary that means the mutation is being inherited from the X chromosome of one parent. Since the male kitten just needs to inherit only one transmuted X chromosome, in order to accede to the condition, while the female kitten might need to receive 2 transfigured X chromosomes, to be able to accede to the ailment, congenital myelin conditions are way more common male cats, rather than in female.

Acquired Myelin Disorders

The acquired demyelination, commonly known as medyelination, is greatly rare and vets aren’t sure of its cause. Tainted food and viruses have been suggested as probable causes. In scientific studies on cats, stamp out food has instigated austere and sudden demyelination that later mended itself when the cat reverted to a more normal diet.


If a cat has any of the following symptoms, the cat might suffer from a hereditary from of myelin deficiency. When an adult cat experiences these symptoms, the cat might have developed a greatly unusual form of assimilated myelin deterioration. Either a form of myelin deficiency must be considered a serious and might cause the following signs and symptoms:

  • Seizures,
  • An incapacity to move or stand,
  • A tremor in the head, trunk, and / or limbs, as well as
  • Delayed movement and reduced reflexes.


The vet may perform a complete physical examination on the cat, taking into consideration the background history of the symptoms and the genetic background. Standard tests include a blood profile, including a complete blood count, chemical blood profile, as well as a urinalysis.

Moreover, if a myelin disorder in cats is suspected, the vet may start by doing a complete physical examination and blood examinations, and ask you to describe symptoms you’ve observed in the cat. A prognosis is commonly based on at least 4 different factors.

  • First factor is the cat’s age at the symptom’s onset.
  • Second factor is the symptoms of the condition itself.
  • Third factor is whether the cat is a male or not.
  • Fourth factor is the elimination of some other possible causes.

Treatments for Myelin Deficiency in Cats

There are presently no effective cures for myelin conditions. The lone way in avoiding hereditary myelin illnesses is avoid breeding the cats, which are carriers. Though assimilated myelin deficiencies are greatly unusual and not very well understood, ensuring that the cat is present on all the vaccinations and eats healthy diet is vital for the general health of the cat.

In addition, some young cats may start to produce and repair myelin on their own over the first years of life, while some other don’t and suffer the symptoms of the condition for the entireness of the lives. The vet may advise you on how you can care for the affected cat and may likely wish to examine the cat regularly. In austere cases, which don’t resolve certainly over a period, euthanasia might be the most gentle option.
