The most common and dangerous diseases of the nervous system in dogs are meningoencephalitis, myelitis, paralysis, paresis, epilepsy, and congenital defects of the central nervous system (CNS).
It is an inflammation of the brain and its membranes. Usually observed in infectious diseases of dogs: plague, leptospirosis, listeriosis, viral hepatitis, etc.
First, the temperature rises to 40-42 degrees, the pupils are dilated, the eyeballs are not mobile, the muscles of the neck and neck are tense, the sensitivity of the skin is increased, the dog is agitated, and convulsions may begin. Then vomiting appears, arousal is replaced by inhibition, disorders of the cardiovascular, respiratory and digestive systems are observed. Often the disease ends in death.
Treatment is prescribed by a veterinarian and consists of the use of glucorticoids, antibiotics and symptomatic drugs.
Paralysis and paresis
Paralysis and paresis occur with inflammation, damage, age-related atrophy of nerve fibers, osteochondrosis. Paresis is characterized by decreased sensitivity and weakness of the muscles for which the damaged nerve is responsible. With paralysis, mobility and sensitivity are completely absent.
Treatment is most effective at the onset of the disease. Apply novocaine blockade, physiotherapy, heating, injected vitamin B1, drugs that improve the conductivity of nerve fibers.
It is characterized by recurring seizures with loss of consciousness. Epilepsy is primary (true) and secondary (symptomatic). True epilepsy in dogs is inherited, appears in the age of three years. It is incurable and accompanies the animal throughout its life.
Symptomatic epilepsy is a complication of an infectious disease, as a rule, affecting the central nervous system: distemper, leptospirosis, viral hepatitis, literiosis, meningoencephalitis is either a consequence of injury or a brain tumor. It can occur at any age. Its course depends on the course of the underlying disease. Therefore, when it is cured, epilepsy may disappear.
The main symptoms of the disease are recurrent epileptic seizures.
Small seizures are carried "on the feet" and last for a few seconds, without losing consciousness. When they are observed dilated pupils, cramps of the masticatory muscles, drooling, twitching of the neck and paws. After a seizure, the dog feels fine.
Before a large seizure, the dog usually worries, then convulsive jerking of the masticatory and facial muscles is observed, the animal falls, loses consciousness, and convulsions begin. The seizure lasts a few minutes. After that, the dog cannot stand for some time.
In epileptic status, several large seizures follow each other almost without interruption, which can lead to the death of the animal.
With true epilepsy, seizures occur with a certain frequency, and with symptomatic, their frequency depends on the course of the underlying disease. To prevent injuries during attacks, the dog must be fixed. Anticonvulsants are prescribed to reduce the frequency and seizure intensity. In secondary epilepsy, it is important to cure the underlying disease.
To prevent diseases of the central nervous system in dogs, stressful situations should be avoided: coarse treatment, increased stress. Prevent, timely diagnose and treat infectious diseases, osteochondrosis, discopathy. Nutrition for older dogs should be balanced.
