Diseases of the nervous system (neurology)

Japanese mosquito encephalitis: causes, symptoms, diagnosis, treatment

Japanese mosquito encephalitis (synonyms - encephalitis B, encephalitis of the Primorsky Territory) is widespread in Primorsky Krai, Japan, Manchuria.

Encephalitis: causes and classification

Encephalitis is an inflammation of the brain substance. Currently, encephalitis is not only called infectious, but also infectious-allergic, allergic and toxic damage to the brain.

Acute lymphocytic choriomeningitis: causes, symptoms, diagnosis, treatment

The causative agent of acute lymphocytic choriomeningitis is a filtering virus isolated by Armstrong and Lilly in 1934. The main reservoir of the virus is gray house mice that excrete the pathogen with nasal mucus, urine and feces. Infection of a person occurs due to the use of food products infected with mice, as well as airborne droplets when inhaled dust. Acute lymphocytic choriomeningitis is more often sporadic, but epidemic outbreaks are also possible.

Epidemic cerebrospinal meningitis (meningococcal infection)

Epidemic cerebrospinal meningitis is caused by gram-negative diplococcus - meningococcal Weixelbaum. The disease is transmitted by airborne droplets. Entrance gates are the mucous membrane of throat and nasopharynx. Meningococci penetrate into the nervous system by hematogenesis. The source of infection are not only sick, but also healthy carriers. The most common cases of meningitis are in winter and spring. Sporadic diseases are noted at any time of the year.

Purulent meningitis

The main pathogens of purulent meningitis in newborns and children - streptococcus group B or D, Escherichia coli, Listeria monocytogenes, Haemophilus influenzae, in adults - pneumococci, staphylococcus, etc. Risk factors include immunodeficiency, craniocerebral trauma, surgery on the head and neck .

Treatment of dyscirculatory encephalopathy

The goal of treatment of chronic cerebral circulatory insufficiency is stabilization, suspension of the destructive process of brain ischemia, slowing down of progression, activation of sanogenetic mechanisms of compensation of functions, prevention of both primary and repeated stroke, therapy of basic background diseases and concomitant somatic processes.

Dyscirculatory encephalopathy: diagnosis

To diagnose chronic cerebral circulatory insufficiency, it is necessary to establish a connection between clinical manifestations and the pathology of cerebral vessels. For a correct interpretation of the revealed changes, careful collection of an anamnesis with an assessment of the previous course of the disease and dynamic observation of the patients is very important.

Dyscirculatory encephalopathy: symptoms

The main symptoms of discirculatory encephalopathy: emotional disorders, polymorphic motor disorders, memory impairment and learning ability, gradually leading to maladaptation of patients. Clinical features of chronic cerebral ischemia - progressive course, staging, syndromic.

Dyscirculatory encephalopathy: a review of information

Dyscirculatory encephalopathy is a slowly progressive brain dysfunction that has arisen as a result of diffuse and / or small-focal damage to the brain tissue in conditions of long-term insufficiency of the cerebral blood supply.

Subdural hematoma

Subdural hematoma is a volumetric accumulation of blood, located between the solid and arachnoid medullary membranes and causing compression of the brain. The vast majority of subdural hematomas are formed as a result of craniocerebral trauma. Much less often they arise in the vascular pathology of the brain (for example, hypertension, arterial aneurysms, arterio-venous malformations, etc.), and in some cases are the result of taking anticoagulants.
