Neurological complications caused by HIV infection

Neurological complications, including dementia, may result from the body defeat HIV. HIV can be overcome cerebral protective barrier, which means that HIV can directly infect cells of the brain and nervous system. Symptoms of such a lesion is very similar to the symptoms of brain injury other infections (toxoplasmosis, cryptococcal meningitis): headache, memory loss, loss of motor control, speech problems, dizziness, seizures. Direct brain lesion immunodeficiency virus is very difficult to diagnose without a puncture cerebrospinal fluid.
Pneumocystic pneumonia
This is an inflammation of the lungs caused by the parasite pneumocystis carinii. This is the most common opportunistic diseases that occur in more than 60% of AIDS patients. Among the most illustrative pneumocystic pneumonia symptoms - dry cough without sputum office (non-productive cough) and rapid shallow breathing.
Professionals who work with HIV-infected recommend them to avoid contact with other HIV-infected patients pneumocystic pneumonia until the past will not be cured.
Progressive leukoencephalopathy
This defeat of central nervous system caused by a virus Kreutsfelda Jacob (Jacob Creutzfeld virus). More than 80% of the population are infected with the virus in childhood, but it does not cause disease in a healthy immune system. When immunodefitsite (especially AIDS) virus is activated and causes PML. Typically, PML occurs in more than 5% of AIDS patients.
Manifestations of the PML are: visual impairment (including blindness) and speech disorder spatial coordination, confusion, and others. In general, the manifestations of PML is very similar to the symptoms of toxoplasmosis, central nervous system lymphoma, cryptococcal meningitis tsitomegalovirus infection. PML Symptoms usually develop quickly, and the fatal injury could be as early as one year after infection.
Toxoplasmosis
Called Tohorlasma gondii, unicellular parasite. Most of the time Tohorlasma gondii infects the brain, but can also infect the heart and lungs. When immunodefitsite symptoms may include headache, catarrhal manifestations, dizziness and seizures. The causative agent of toxoplasmosis found in the soil, and raw wool cat food (not held enough heat treatment). According to the American Institute alergologii and infectious disease, almost 30% of the population are carriers Tohorlasma gondii, but with a healthy immune system, it does not violate the activities of the body. An exception may be as pregnant women, whose Tohorlasma gondii can cause a slight deterioration in health. Cure toxoplasmosis is extremely difficult: it is possible to deter the development of drugs, but to completely eradicate the organism from Tohorlasma gondii is not yet possible.
People learn that they are HIV-positive should immediately take the test for antibodies to Tohorlasma gondii, so as not to miss the moment for a timely start of treatment. Also, HIV-infected people should avoid not been sufficient heat treatment of food products, especially pork. Also critically important to wash their hands thoroughly after contact with animals, soil, raw meat, and well-washed fruits and vegetables before eating. Avoid contact with the faeces of animals, especially cats. If the cat lives in a house with an HIV-infected person, you need to test it for any Tohorlasma gondii.
