Symptoms of hiv
They are divided into tonic, in which there is maintained muscular contracture, and tonic-clonic, in which there are altered periods of contractions and relaxation. The seizure may also be focal or generalized.
In some people, there may be hereditary factors that affect the neurons of the brain in such a way that a disposition to seizures is present. In these cases, seizures occur spontaneously, without an immediate cause, and recur over time. In other cases there may be deformities or malformations of brain development during embryogenesis.
Seizures may be idiopathic, i.e., they are usually chronic seizures that occur without an identifiable cause, in persons with or without a family history of epilepsy or seizures. Other common causes of seizures or epileptic seizures include:
The occurrence of a seizure and its symptomatic expression differs depending on the neural area affected. If the affected neural network is the visual cortex, the clinical manifestations will be expressed in visual manifestations. And so with other regions of the cortex: gustatory, sensory or motor.
Causes of AIDS
Epilepsy is a brain disorder in which a person has repeated seizures over a period of time. Seizures are episodes of uncontrolled, abnormal activity of nerve cells that may cause changes in attention or behavior. Causes
The doctor will perform a physical examination. This includes a detailed examination of the brain and nervous system. An EEG (electroencephalogram) will be done to check the electrical activity in the brain. People with epilepsy often have abnormal electrical activity seen on this test. In some cases, the test shows the area of the brain where seizures begin. The brain may appear normal after a seizure or between seizures.To diagnose epilepsy or plan surgery for epilepsy, you may need:Tests that may be done include:Often, a CT scan or MRI of the head is done to find the cause and location of the problem in the brain.Treatment
HIV encephalitis treatment
In industrialized countries such as the United States, the cancer and HIV landscape has been changing as HIV treatment has improved. For example, some AIDS-defining conditions have become less common as more people have received effective HIV treatment. As people with HIV have been living longer, they have also been developing other cancers that are more common among older people. The use of anti-HIV drugs (antiretrovirals) has also resulted in improved cancer survival rates for people with HIV, as many people are now able to receive full doses of chemotherapy and other conventional cancer treatments, which may not have been possible before.
In most cases, epidemic Kaposi’s sarcoma produces purple or brownish-tinged spots (lesions) on the skin or in the mouth. Kaposi’s sarcoma may also involve the lymph nodes and other organs, such as the digestive tract, lungs, liver and spleen.
Neurological complications of hiv
HIV (human immunodeficiency virus) is the virus that causes AIDS (acquired immunodeficiency syndrome). HIV attacks the immune system by destroying specific white blood cells called CD4-positive (CD4+) T cells that are vital for fighting infection. The resulting shortage of these cells makes HIV-infected persons vulnerable to other infections and diseases, and to further complications.
Although HIV infection and AIDS primarily affect the immune system, they also disrupt the nervous system and can cause a wide range of serious neurological disorders, especially if HIV is left untreated and progresses to AIDS. Many of the most serious neurological conditions can be prevented by antiretroviral therapy. However, even people receiving this treatment may develop less severe neurological and cognitive difficulties.
The nervous system can be affected directly by the HIV virus, by certain cancers and opportunistic infections resulting from a weakened immune system, or by the toxic effects of drugs used to treat the infection. Other neurological complications may be influenced by the HIV virus, but are not directly caused by it.
