What is feline vestibular syndrome? Causes and symptoms of feline vestibular syndrome! Vestibular syndrome is a relatively common neurological syndrome in small animals, with various causes . From the point of view of pathogenic source, it can be divided into central and peripheral. At the same time, it also includes congenital and acquired. It is a disease of cat body balance caused by the central damage of the vestibular nucleus located in the medulla oblongata and the vestibular nerve part of the 8th cranial nerve.
First, vestibular disorders include primary or secondary
Primary are:
1. Vestibular syndrome in cats : Acute, idiopathic, non-progressive vestibular disorders. Idiopathic disease, presumably due to Cuterebra fly larvae.
2, Congenital vestibular syndrome
Hearing loss, vision loss, persistent head tilt or tremor, nystagmus, and other tests without characteristic changes.
Secondary:
①Secondary to tumor
②Central or cerebellar vestibular disease
3. The causes of peripheral vestibular syndrome include:
① idiopathic vestibular syndrome; ② inner ear infection; ③ nasopharyngeal polyps; ④ hypothyroidism; ⑤ tumors, including squamous cell carcinoma, adenocarcinoma and lymphoma;
II. Metabolic diseases
Portal vein short circuit: The condition worsens after meals. Visual impairment, blind exercise, depression, lethargy. Occasionally, hind limb spasm, blind exercise, intermittent asthma, better appetite, salivation, and sudden loss of vision. The biochemical detection value of BUN in PSS patients is lower than the reference value, the detection value of ALT and ALP is in the normal range or high, and the blood nitrogen concentration is significantly increased. There are urine uric acid crystals. X-ray examination shows that the liver is small.
Three, Endocrine Diseases
Hyperthyroidism: polyphagia, polydipsia, polyuria, excitement, muscle tremors, screaming, incompetence, hypertensive retinal detachment blindness.
1. The possibility of being caused by Cuterebra fly larvae is extremely small, and feline vestibular syndrome can be ruled out
2. The retina is intact, there is no excitement, and there are no symptoms of hyperthyroidism such as excessive diet and polyuria, which can be excluded.
3. The blood ammonia test value is in the normal range, there is no salivation phenomenon, the symptoms are not related to eating, and portal vein short circuit can be ruled out
4. Central cerebellar symptoms are not obvious, and secondary vestibular disease can be excluded
5. The blood test is within the normal range, which can exclude listeria and other infectious diseases.
IV. Idiopathic vestibular disorders
< p style=text-indent:2em;>One of the main types of vestibular syndrome, with pure vestibular symptoms, acute balance disturbance, marked head tilt, impaired judgment, ataxia, and no other symptoms. There is no age limit for the onset of cats. Most of the symptoms appear in late summer and early autumn. The initial symptoms appear suddenly, and then become significantly weakened. It is easy to be misdiagnosed as spasticity and stroke. This symptom should be distinguished from simple otitis media.V. Treatment
Infectious diseases, antibiotics and corticosteroids should be used while treating the primary disease. Trauma can be given a small amount of sedatives for the purpose of suppressing inflammation in a short time, and a small amount of corticosteroids can also be used.
In otitis media, corticosteroids may cause purulent ulcers and are prohibited. Sulfonamides can be used for Toxoplasma gondii.
The disease varies according to the cause and severity of the disease after recovery. There are many congenital or prognostic ones with good prognosis. Infectious, neoplastic, B-vitamin deficiency, and traumatic cases vary from case to case.
