Seizures and headaches are the most common symptoms. However, confusion, lack of attention to people and surroundings, difficulty with balance, excess fluid around the brain (called hydrocephalus) may also occur. The disease can result in death.
Cysticercosis is a parasitic tissue infection caused by larval cysts of the tapeworm Taenia solium. These larval cysts infect brain, muscle, or other tissue, and are a major cause of adult onset seizures in most low-income countries.
The Spirometra tapeworm can live in humans for up to 20 years. A man in China experienced seizures and other mysterious symptoms for years before doctors finally found the cause: He had a rare parasite living in his brain, which had likely been there for more than a decade, according to news reports.
Tapeworms can cause digestive problems including abdominal pain, loss of appetite, weight loss, and upset stomach. The most visible sign of taeniasis is the active passing of proglottids (tapeworm segments) through the anus and in the feces.
Doctors think the man contracted the parasite in Mexico more than a decade ago after eating undercooked pork. AUSTIN, Texas -- Doctors say it's a miracle after an Austin man successfully had a tapeworm removed from his brain.
Symptoms of neurocysticercosis depend upon where and how many cysts are found in the brain. Seizures and headaches are the most common symptoms. However, confusion, lack of attention to people and surroundings, difficulty with balance, excess fluid around the brain (called hydrocephalus) may also occur.
Sometimes, the tapeworm leaves the body on its own. This is why some people never have symptoms or only have mild symptoms. If a tapeworm doesn't leave your body, your doctor will recommend a treatment based on the type of infection.
Another less common group of tapeworms called Echinococcus is of increasing concern as a threat to human health. These tapeworms cause serious, potentially fatal disease when humans become infected.
Eating undercooked meat from infected animals is the main cause of tapeworm infection in people. Although tapeworms in humans usually cause few symptoms and are easily treated, they can sometimes cause serious, life-threatening problems.
Left untreated, adult tapeworms can live in a host body for up to 30 years. Their length varies, but they can grow to be anywhere from 6 to 22 feet.
Management and Treatment
You can easily kill tapeworms with anthelmintic drugs, including praziquantel (Biltricide®), albendazole (Albenza®) and nitazoxanide (Alinia®). Healthcare providers usually recommend praziquantel because it also paralyzes the worm, forcing it to dislodge from your intestinal wall.
The diagnosis of neurocysticercosis usually requires MRI or CT brain scans. Blood tests may be useful to help diagnose an infection, but they may not always be positive in light infections. If you have been diagnosed with cysticercosis, you and your family members should be tested for intestinal tapeworm infection.
Many times, people can be infected for long periods of time without even knowing they have a tapeworm infection. While viral or bacterial infections can disappear in a matter of days or weeks, a tapeworm could be with you for years.
Weight loss — parasites can cause nausea and poor nutritional absorption, which can lead to weight loss. Chronic fatigue syndrome — parasites steal your nutrients and disrupt your intestinal microbiome, resulting in fatigue and brain fog.
After people eat food contaminated with the tapeworm's eggs, secretions in the stomach cause the eggs to hatch into larvae. The larvae enter the bloodstream and are distributed to all parts of the body, including the brain and spinal cord.
The most common tapeworm infection in Australia is caused by dwarf tapeworm. There is also a risk in Australia of contracting a serious condition called hydatid disease from the eggs of a type of tapeworm called Echinococcus granulosus found in dog faeces (poo).
Humans become infected by eating raw or undercooked infected beef or pork. Once ingested, cysticerci attach to the small intestine and develop into adult tapeworms over the course of 2 months. The adult tapeworms produce proglottids that mature, detach, and migrate to the anus and are then passed in the feces.
An adult dwarf tapeworm can live for 4-6 weeks. However, once you are infected, the dwarf tapeworm may reproduce inside the body (autoinfection) and continue the infection.
Tapeworm infections usually don't cause complications. Problems that may happen include: Anemia. Long-term infection with a fish tapeworm may lead to the body not making enough healthy red blood cells, also called anemia.
If you have a tapeworm infection, you may not have any symptoms. But some people have nausea, stomach pain, weakness, or diarrhea. You might notice a change in appetite (eating more or less than usual). And since the tapeworm keeps your body from absorbing nutrients from food, you may lose weight.
Doctors in India were stunned to remove a tapeworm measuring more than 6 feet through a patient's mouth, according to a report published this week in the New England Journal of Medicine.
Diagnosis of tapeworm infection
A health care provider tests for a tapeworm infection in the intestines using a test of a stool sample. A lab test may find pieces of tapeworms or eggs. You may give a sample on more than one day.
Not usually. In fact, a tapeworm is more likely to make you lose your appetite. That's because the worm can irritate your bowels when it attaches to them with its circular suckers (and, in some cases, its movable hooks).
The death rate is over 97%. Only four people have survived out of 154 known infected individuals in the United States from 1962 to 2021.
If the larval worm enters the nervous system, including the brain, it can result in a condition known as neurocysticercosis. Infection of this kind can often cause epilepsy once inside the brain.
