Black-brown hunter dog (detail introduction)
Everyone may be unfamiliar with hydrophilic symptoms. It is indeed not very common in this disease. The so -called hydrophilic disease is due to the increasing cerebral ventricular system due to the manufacturing and absorption of cerebrospinal fluid. If the condition is severe, surgery and careful care are needed, what are the causes of pheasant encephalopathy? Let's do a simple understanding.
The primary hydrophilic disease is abnormal due to the re -absorption of the spinal liquid of the spider film. Other primary hydrophilic disease may also be blocked due to the blockage of the medium cerebral water guidance. There are also special cases caused by the obstruction of the Mongolian Roche. Although primary hydrophilic disease is hereditary in a special variety (for example: Yorkshire (details)). In some playing dogs, the incidence is quite high (such as Chihuahua, Yorkshire, Manchester, Pomeranian, small VIPs), and there are types of round head shapes (such as: British bull head stalks (details introduction),, for details), in detail Boston Standard, Beijing Dog and Lhasa Dog)
Clinical symptoms of hydrophilic disease are common: epilepsy, poor vision, slow learning ability and dementia. In some (not all) cases (not all) of congenital hydrophilic diseases, you will find that the gate is not atresia. Of course, the phenomenon of incomplete lock in the door cannot be regarded as a basis for diagnosis, because many animals with the same phenomenon do not have water and encephalopathy. Many cases of primary hydrophobia have round and protruding skins. Some cases will have double -eyed strabismus, primary hydrophilic disease, and their clinical symptoms change slowly, and some sick animals will gradually stabilize. There are also a small number of cases of cases that suddenly deteriorate. In the anatomy, there are often bleeding and meninge rupture in the brain. This pathological phenomenon is still unknown.
The cause of secondary hydrophilicism is that the liquidity of the cerebrospinal liquid is damaged. The possible reason may be due to the blockage of the brain chamber (such as brain tumor) or the velvet defect of the cerebral spider membrane, which causes the cerebrospinal fluid to absorb poorly. The cause of poor absorption may be caused by ventricular infection. The etiology caused by the water brain may also cause the stenosis of the midbrain water pipe. When the animal dies due to the death of the hydrophobia, this phenomenon is often not found (medium -brain water tube stenosis). Diseases often have a history of central nervous infection or head trauma. Insufficient vitamin A can also cause absorption disorders to the spinal fluid. Secondary hydrophilic disease usually becomes sustainable and comprehensive increase in intracranial pressure. Therefore, it is also difficult to judge the rise of intracranial pressure due to the original course or hydrophilic disease.
