Neurocysticercosis(NCC) is the most common parasitic infection of the brain affecting more than 50 million people all over the world. NCC is caused by infection of the larvae of the pig tapeworm Taenia solium(TS). Pigs become infected when they ingest contaminated human faeces. If someone ingests diseased (measly) pork meat containing larva forms of this tapeworm or ingests its eggs when eating contaminated foods, the parasite fins its way to the small intestine where they become mature. From here the parasite spreads to the brain to form of cystic lesions, also affecting the eyes, muscles or spinal cord.
This parasite can live for years sometimes for entire life-times in the brains of humans who can be free of symptoms, particularly so in HIV infected patients. In HIV patients where the immune system is compromised the parasite remains alive far longer in the brain, but its is a two way street. Neurocysticercosis debilitates the body's defense system and these patients become much more susceptible to get infection and are more prone to develop AIDS. In HIV-positive patients with NCC, epilepsy, epileptic attacks and seizures are the symptoms most commonly observed.
In non-HIV patients the parasite symptoms differ from country to country but in general the most common symptoms include epileptic attacks , headaches, visual and skin problems, and psychiatric manifestations. Any person living, visiting or in close contact with persons from endemic areas such as Latin American, Asian, or African countries could be a candidate for NCC. If you are in that group and you developed epilepsy later in your life (though younger ages are not an exclusion criteria) you could be a candidate. Diagnosis by a health professional could rule out NCC as a cause. Radiographic tests such as Computer Tomography (CT Scan) of the brain is the best confirmatory test, as it identifies most of the cystic lesions and also the head of the parasites (see image to the right). The CT Scan test is available in most cities in South Africa and for patients
requiring special care the New Nelson Mandela Academic Hospital a National Reference Center is an option. Alternative ways do exist in case CT Scan is not available.
The medication of choice for infection of the brain by this tapeworm is praziquantel or albendazol taken with steroids under medical supervision. These anti-parasitic medications kill parasites in all stages of their development in the human brain, eyes or muscles. Most patients respond very well to one-day treatments with praziquantel. However, for people living in endemic areas who remain susceptible to re-infection, periodical treatment is necessary.
The good news is that after the treatment the damage to the brain is 100 % reversible in most cases and only a few require intensive medical attention.
National figures for NCC remain unknown. NCC is a disease of poverty and underdevelopment and its dissemination is permanent in areas where the population have a limited or non-existent access to primary health care attention, health education, proper access to toilet facilities, proper refuse disposal, safe and clean water, electricity, employment, and money. The former Transkei areas of Southern Africa are perhaps hardest hit. According to Prof Foyaca patients are treated for NCC with young children more so than adults. While this situation persists the number of infected immigrants to developed areas will continue increasing. Patients diagnosed in Soweto, Cape Town, and other places are migrants from impoverished regions of Southern Africa.
Although we can't expect radical changes we may contribute to reduce the risks to this disease by:
Coming soon to a family member near you courtesy of uncontrolled illegal and uncontrolled legal immigration of people with various disgusting diseases and parasites from third world pest holes. Another reason the thank GWB II for cracking down in this problem (OH wait, he doesn't want to crack down on them. He wants to give them amnesty)
For them to claim he "struggled" with this it must have been known. If it was known it must have been treated. If the worms were gone and he was not impaired then why did he do a superman off of the roof of his Mercedes? If there was irreversible impairment why was he driving? Seems to me there is something else at work here besides tapeworms.
Perhaps this poor community minded guy with a great sense of humor who smashed someone's car and would have killed a biker if the car hadn't there was struggling with the tequila worm instead.
This really concerns me. I've been working at it since age 5.
