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. Toxoplasma Brain Parasite Modulates Parkinson’s Signaling Pathways.
Parasite Linked with Alzheimer’s and Parkinson’s Diseases, Epilepsy, and Cancer.
If infectious bacteria, viruses or fungi reach the brain they can activate special immune cells in the brain called microglia. When microglia are activated, they can cause inflammation in the brain. This type of inflammation is thought to be involved in the progression of dementia by causing nerve cell death.
Infection by parasite could be linked to development of Alzheimer’s study reports.
