Infection with the brain parasite Toxoplasma gondii may increase the likelihood for certain brain disorders, including Parkinson's and Alzheimer's disease, a systematic analysis suggests.
Parkinson's disease is caused by a loss of nerve cells in the part of the brain called the substantia nigra. Nerve cells in this part of the brain are responsible for producing a chemical called dopamine.
The main risk factor is age, because Parkinson's disease is most commonly found in adults over the age of 50 (although diagnoses can occur in much younger people). Men also have a higher risk of Parkinson's disease than women.
Researchers have found a connection between an infection with the parasite Toxoplasma gondii and neurodegenerative diseases such as Alzheimer's. The study, “Toxoplasma Modulates Signature Pathways of Human Epilepsy, Neurodegeneration & Cancer,” was published in the journal Nature.
Because Parkinson's primarily affects people as they grow older, the steady increase in humanity's average age means an inevitable increase in the prevalence of Parkinson's.
Research suggests that stressful life events may increase the risk of Parkinson's disease. In addition, animal studies indicate that stress damages dopamine cells, resulting in more severe parkinsonian symptoms. In humans, acute stress can worsen motor symptoms, including bradykinesia, freezing, and tremor.
Parasites - Cysticercosis. 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.
Evidence from the lab of Raffi Van Aroian, PhD, shows that short-term human hookworm infection, even at low levels, can cause rapid, acute and measurable cognitive impairments in spatial memory among a mammalian animal model.
Parkinson's Disease (PD) has a multifactorial aetiology, with a complex interaction of genetic and environmental risk factors. Several environmental and lifestyle factors have been associated with PD and especially smoking, coffee and tea intake have been linked to reduced risk[1][2].
By the time Parkinson's is diagnosed, most people have lost an estimated 60 to 80 percent of their dopamine-producing cells in the substantia nigra. While loss of dopamine accounts for the characteristic features of the disease, recent studies have revealed that a number of other brain systems are also damaged.
Slowing of movement
This is perhaps the most important early symptom of Parkinson's disease. Patients often complain of being weak when in fact they are slow. Slowed movements can make simple tasks difficult and time-consuming. Steps become shorter.
Recent clinical evidence even suggests that the degenerative processes of Parkinson's disease observed in the brain may actually originate in the gut, and only spread to the central nervous system through the brain-gut axis as the disease progresses.
The current literature therefore suggests that using certain probiotic mixtures may improve the gastrointestinal symptoms of PD, although these treatments have not been compared to increasing prebiotic use, which may be even more effective. Even less data supports the use of probiotics for the motor symptoms of PD.
There's currently no cure for Parkinson's disease, but treatments are available to help relieve the symptoms and maintain your quality of life. These treatments include: supportive therapies, such as physiotherapy.
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.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
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.
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.
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.
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.
Parkinson's disease (PD), like most common disorders, involves interactions between genetic make-up and environmental exposures that are unique to each individual. Caffeinated-coffee consumption may protect some people from developing PD, although not all benefit equally.
“Movement, especially exercises that encourage balance and reciprocal patterns [movements that require coordination of both sides of your body], can actually slow progression of the disease,” she says.
Canadian-born actor Michael J. Fox, while working on a CBC sitcom as a teenager, contracted a virus that some researchers say may have caused him to later develop Parkinson's disease.
