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.
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.
Abstract. Memory impairment has been associated with chronic Chagas disease (CD), a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi.
gondii infection in rodents and in primates can cause subtle behavior changes, including loss of the animals' aversion to the smell of the urine of their natural predators. Some epidemiological studies in humans have linked T. gondii infection with neurological disorders such as Parkinson's and Alzheimer's diseases.
Researchers from Tufts University and the University of Oxford have found that two common viruses—the varicella zoster and herpes simplex viruses—likely constitute a pathway that leads to Alzheimer's disease.
The authors found that after infection with the parasite, mice had impaired learning and memory function, just as they would with Alzheimer's disease. The infection also altered their brain chemistry compared to uninfected mice. In one group, the infection increased the likelihood of Alzheimer's disease.
In humans, hookworms appear to impair memory and other forms of cognition, although definitive data are hard to come by. Here we study the impact of a human hookworm parasite, Ancylostoma ceylanicum, on cognition in hamsters in a controlled laboratory setting.
There are two kinds of common parasitic infections:
Pinworms, whipworms, and hookworms are all types of roundworms (1) that can cause digestive problems, mood swings, abdominal pain, brain fog, and weight loss.
Amnesia can occur in many common neurological disorders like Alzheimer's disease and other forms of dementia, stroke and traumatic brain injury, as well as other systemic illnesses that affect the brain.
In Nicaragua and other developing countries tapeworm infections are common, and the larvae can migrate into the brain—a condition called neurocysticercosis. Usually the infection causes seizures as well as large brain cysts that are obvious on an MRI.
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.
Parasitic infections often cause intestinal illness, with symptoms like diarrhea and vomiting. But they can also give you itchy skin rashes or infect other parts of your body, like your brain or lungs.
The lab might look for antibodies to T. solium (cysticercosis serology test) or for specific parts of the parasite (antigens). Lumbar puncture: If your provider thinks you have cysticercosis of the brain or spinal cord, they may test your cerebrospinal fluid (CSF) with a lumbar puncture.
More than 30 million Americans are infected with a brain parasite spread by cats and contaminated meat, but most will never show symptoms.
Hookworm infection is most common in the developing world where proper hygiene and sanitation are a challenge. Long-term infection is known to cause severe developmental and cognitive impairments.
Why? Most people do not know they are infected or at risk, or don't have access to appropriate care. And often, health care providers are unfamiliar with these parasitic infections, and may not diagnose or treat them appropriately.
A memory worm was covered with a substance that could remove a short period of memory from any being who came in direct contact with it. The substance was also in the worm's fangs; if a worm bit an individual, the individual could lose decades worth of memories. ( TV: The Snowmen)
The clinical manifestations of brain schistosomiasis are varied. Headache, papilledema, visual abnormalities, and seizure are common manifestations in cerebral schistosomiasis, while nausea, vomitting, brain hernia, and ataxia are more common in cerebrellum and brainstem schistosomiasis.
The worms can spread to the spinal cord, causing myelopathy. This results in pain, urinary retention, and weakness of the regions below the level of infection. Permanent paralysis can result. 22 In other cases, the schistosomiasis can affect the brain, leading to epilepsy or elevated intracranial pressure.
Spirochetes are a type of bacteria that cause diseases like syphilis, Lyme disease and gum disease. We have known for a long time that, under certain conditions, some chronic spirochete infections such as syphilis can cause dementia.
Brain infections such as Lyme disease, syphilis, or HIV/AIDS. Overuse of medicines, such as barbiturates or (hypnotics) ECT (electroconvulsive therapy) (most often short-term memory loss)
