Vaccines and Brain Damage

A spinal tap does carry some risk for certain animals. These medications include cytosine arabinoside, cyclosporine, azathioprine, leflunomide and procarbazine. In one retrospective study of 42 dogs with GME , median survival time for dogs with focal versus disseminated disease was 114 and 14 days, respectively, and dogs with focal forebrain signs (e.g., seizures) had significantly longer survival times (>395 days) than did dogs with focal signs in other areas of the CNS (59 days). So, we have had to scratch the breed distinction. In mildly affected animals the medication can be tapered and stopped after three to six months. Many treatments have been used, but typically a combination of medications to suppress the immune system and steroids are used. Dr.

Imaging of the brain is usually done first in cases where encephalitis is not the chief concern. A spinal tap will also be necessary, which unfortunately means your pet will require general anesthesia. Since the CSF usually is inflammatory, dogs are tested for infectious disease with serology or PCR analysis for the presence of infectious agents. Negri body-like inclusion bodies and Toxoplasma-like organisms have been reported within lesions; however, the occurrence of GME within countries known to be rabies-free [19,2] and negative serology results for protozoal organisms in large studies [40] would tend to argue against these aetiologies. 19 (4): 553–9. My wife and I cut out the steroid (see below), but continued to give the antibiotics until we were out. Publisher: Mosby.

Ettinger and E.C. As with humans it is rather the nymphs and even more numerous … Some dogs may have an apparently normal spinal tap but the MRI scans show abnormalities consistent with the inflammation within the brain. If vaccinated dogs are attacking their own albumin, then neurological function could be impaired. Her hyper-panting and “franticness” and non-stop pacing for 36 hours became terrifying for her and us. Unicellular plants, Prototheca wickerhamii and P zopfii , can also produce an eosinophilic meningoencephalomyelitis in dogs. Countries with high-risk areas (incidence of clinical TBE cases is > 10 per 105 inhabitants) are Russia, Latvia, Lithuania, Slovenia, and Estonia.

Neurological abnormalities included a head aversion to the left, decreased menace response on the right, and decreased postural reactions in the right pelvic and thoracic limbs. This can help to confirm the presence and type of inflammation and, perhaps more importantly, tests can be carried out to look for an infection. Common dose-dependent side effects of steroids include increased thirst and hunger (consequently urination and weight gain), lethargy, panting, and increased risk of infections (respiratory, urinary etc). doi:10.2460/javma.2004.225.1211. 1992. How often this is required will be dependent on your pet’s response to treatment. You are going to have to do your own thorough research, gaining an understanding of what and why and the mechanisms involved.

It will occasionally give us a complete diagnosis as in the cases of mycotic diseases if the organism is seen directly in the sample. Ask your veterinarian what you can do to support your dog’s recovery — they may recommend supplements, pain medications, an exercise regimen, and/or physical therapy. In recent studies, anti-astrocyte autoantibodies were detected in the cerebrospinal fluid (CSF) of dogs with NE [19,32]. Chihuahuas and Shih Tzus can also suffer from Pug Dog Encephalitis. Early diagnosis is difficult. If a dog survives the initial few days, however, many cases of MUE will go into remission with aggressive treatment. Not in my opinion!

Other rare non-infectious causes include pre- (inflammation that will turn into cancer with time) and para- (cancer outside of the nervous system having distant effect – in that case inflammation of the brain) neoplastic disorder. They progressively become lethargic, anorexic and nauseous and frequently vomit. When bacterial meningitis occurs in dogs, though they rarely do except in young dogs, they are usually non-contagious. There are several forms of GME; focal, multifocal and ophthalmic and a dog can have more than one type. The virus can easily cause meningitis or encephalitis or meningoencephalitis. The histopathologic findings at necropsy include severe, non-suppurative leptomeningitis and extensive, multifocal, often cavitating necrosis of both gray and white matter of the brain, with evidence of inflammation. Further, veterinary vaccine manufacturers might pay veterinary costs associated with illnesses that arise post vaccination, but they frequently deny any culpability (it’s just a “goodwill gesture”), and they frequently make pet owners sign gagging orders before money is handed over – which of course means that they are no longer allowed to talk about their friend in relation to the potential cause of his death or illness.

Culture of Actinomyces from the CNS and a definitive diagnosis has not been previously reported in domestic animals. Most cases of meningitis are due to bacterial or viral infection. Symptoms include headache, fever, confusion, drowsiness, and fatigue. The dog will never develop Pug Dog Encephalitis (PDE) / Necrotizing Meningoencephalitis (NME) but since it carries the mutant gene, it can pass it on to its offspring with the probability of 50%.
