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.
The infection is treated with albendazole or praziquantel (drugs used to treat parasitic worm infections, called antihelminthic drugs). However, if a person has many cysts, antihelminthic drugs may kill many organisms, causing the brain to swell significantly.
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.

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.
And those cysts can end up in people's brains, causing a disease known as neurocysticercosis. “Nobody knows exactly how many people there are with it in the United States,” says Nash, who is the chief of the Gastrointestinal Parasites Section at NIH. His best estimate is 1,500 to 2,000.
In some cases, they may cause permanent nerve or eye damage, even blindness. How do hookworms harm people? Hookworm larvae typically move around within the skin causing inflammation and red, itchy tracks in the affected skin. This is called cutaneous (skin) larva migrans.
The so-called brain-eating amoeba is a species discovered in 1965. Its formal name is Naegleria fowleri.
Often they can go unnoticed, with few symptoms. But many times these infections cause serious illnesses, including seizures, blindness, heart failure, and even death.
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.
Worms are mainly spread in small bits of poo from people with a worm infection. Some are caught from food. You can get infected by: touching objects or surfaces with worm eggs on them – if someone with worms doesn't wash their hands.
Adult male worms are greenish-yellow to brown in color and up to 6.2 cm (2.4 in) long and 0.2 mm (0.008 in) wide. Females are darker brown to red to black in color and up to 9 cm (3.5 in) long and 0.25 wide (0.01 in).
Of all parasitic diseases, malaria causes the most deaths globally. Malaria kills more than 400,000 people each year, most of them young children in sub-Saharan Africa.
Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms. Although the worms that cause schistosomiasis are not found in the United States, people are infected worldwide. In terms of impact this disease is second only to malaria as the most devastating parasitic disease.
Consequences of Parasite Invasion of the Brain
In addition to life-threatening conditions, parasitic infections of the brain can cause disturbances of the brain function. For instance, they are a common cause of seizures and epilepsy (Taenia solium larvae, P.
X-ray, Magnetic Resonance Imaging (MRI) scan, Computerized Axial Tomography scan (CAT)These tests are used to look for some parasitic diseases that may cause lesions in the organs.
They found that both men and women infected with T. gondii were more extroverted and less conscientious than the infection-free participants. These changes are thought to result from the parasite's influence on brain chemicals, the scientists write in the May/June issue of the European Journal of Personality.
Parasite infections can be a cause of mental illness through biological and socio-environmental paths. The inflammation caused by parasite infections affects the brain and CNS via the blood brain barrier, activation of the vagus nerve and immune cells.
Most people don't experience serious complications from pinworm infections, but in rare cases the following complications can occur: Urinary tract infections (UTIs). UTIs can develop if you do not treat the pinworm infection. Vaginitis and endometritis.
Most worm infections are not serious and can be easily treated with medicine.
You can get tapeworms from food or water that's contaminated with worms or eggs. If you swallow tapeworms, they'll grow up in your intestines. They can live in a person for 30 years.
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.
Cut most species of flatworm in half, and you end up with two flatworms. The front half will grow a new tail and, more impressively, the back half will grow a new head—complete with a fully functioning brain. But a few species of these worms mysteriously lack this ability, at least when it comes to regrowing a head.
They discovered that all of the species could regrow an amputated tail, “but surprisingly few could regenerate a complete head,” the scientists wrote in the study. (All of the headless worms did survive for weeks or months after their decapitation, however.)
About half the world's population (over 3 billion people) are in infected with at least one of the three worms forming what Columbia University parasitologist Dickson Despommier calls the "unholy trinity"—large roundworm, hookworm and whipworm.
