Which Infectious Canine Disease Can Cause Neurological Problems?

Depending on which office of the CNS is inflamed, inflammatory CNS affliction can be more precisely divided into meningitis (inflammation of the meninges), encephalitis (inflammation of the brain) and myelitis (inflammation of the spinal cord). Each veterinary neurology condition tin occur primarily on its ain, only information technology is usually combined with at least ane of the other 2 (meningo-encephalitis, meningo-myelitis).

What are the causes of inflammatory CNS disease?

Causes of inflammatory CNS disease can be either infectious or non-infectious. Infectious causes are probably the least mutual and tin exist due to viral (Distemper in dogs, Feline-infectious peritonitis, FIV), bacterial, protozoal (Toxoplasma, Neospora) or fungal agents. Non-infectious causes are more common and include breed-specific disorders of Yorkshire terriers, Maltese and Pug, also as presumed immune-mediated disorder (granulomatous meningo-encephalitis also known as GME).

The latter is probably the most common cause of inflammatory CNS disease in dogs. Why the immune system of a sudden becomes 'over-excited' and decides to inflame the CNS remains a affair of speculation. Other rare non-infectious causes include pre- (inflammation that will plough into cancer with time) and para- (cancer outside of the nervous organisation having afar effect – in this case inflammation of the brain) neoplastic disorder.

What are the signs of inflammatory CNS affliction?

The signs of inflammatory CNS disease vary according to which part of the CNS is inflamed (brain, spinal string and/ or meninges).

When meningitis occurs on its own, hurting, stiffness of the gait, reluctance to move the neck and hunched-up back are the most mutual signs. Fever is only seen in less than one-half of the cases and its absence can therefore non be used to discard the possibility of meningitis. Encephalitis and myelitis are associated with signs of neurological disorders in dogs and cats reflecting which part of the nervous system is inflamed.

How do you diagnose inflammatory CNS illness?

Unfortunately, the diagnosis of inflammatory CNS illness cannot exist based solely on the clinical and/ or neurological signs as other neurological conditions (tumour, drain) can potentially cause similar signs. Contrary to  common conventionalities, fifty-fifty the most severe neurological disorders in dogs, such as meningitis or encephalitis, may not testify upward in blood tests.

Further tests such as CT-scanner or MRI can reinforce the suspicion of inflammatory disease. Cerebrospinal fluid analysis (come across fact sheet) collection is probably one of the most useful tests. Not just this can help to ostend the presence and type of inflammation, but important tests can be carried out to look for an infection. On rare occasions, cerebrospinal fluid can be normal despite the presence of an inflammatory CNS affliction.

How can inflammatory CNS affliction be treated?

Treatment of inflammatory CNS disease depends on the primary cause.

In the case of an infectious crusade, treatment consists mainly of antibiotics, with the exception of fungal and viral causes.

In the case of a not-infectious crusade, handling is based on trying to counteract the 'over-excitation' of the immune system past giving immuno-suppression drugs. A high dose of corticosteroids (prednisolone) is the mainstay treatment. Other drugs such equally azathioprine, cytarabine, mycophenolate, cyclosporin, cyclophosphamide tin can besides be used in combination with corticosteroids. The short-term aim of the handling is to return the animate being to normal using a high dose of medication. One time this has been accomplished, the medium-term aim is to slowly reduce the quantity of drug without the beast relapsing. The long-term aim is ideally to take the fauna off any drug, only more unremarkably to find the lowest dose of medication that will keep him/ her free of signs. The main chance of using these drugs is to close down the bone marrow, making the animate being more than decumbent to infection.

Can inflammatory CNS disease exist cured?

In the bulk of cases, inflammatory CNS disease can be controlled. This means that the animal can take a normal life simply volition need to remain on medication for many months, or fifty-fifty years. Unfortunately, a pocket-size percentage of animals with too severe inflammation may not ameliorate despite ambitious treatment. In some cases, animals that have returned to normal and were taken off medication take experienced relapses months subsequently.
