    Study Notes

    Infectious Diseases Affecting the Nervous System

    • Variant Creutzfeldt-Jakob Disease (vCJD) symptoms include insomnia, weight loss, and memory failure, with progressive muscle control deterioration.
    • vCJD is caused by an abnormal form of prion that can remain dormant for many years.
    • Rabies is transmitted through contact with infected animal body fluids, with an incubation period of 1-2 months. It replicates in muscle cells then moves into neurons.
    • Rabies symptoms include anxiety, impaired swallowing, and can lead to coma and death, with two main forms: furious rabies and dumb rabies.
    • Poliovirus is transmitted through the fecal-oral route, with symptoms ranging from asymptomatic to paralysis, and it can lead to muscle atrophy and deformities.
    • Tetanus symptoms include muscle contraction inhibition and rigid “spastic” paralysis, with a unique tennis racket morphology of Clostridium tetani.
    • Botulism has three types and prevents muscle contraction, leading to double vision, difficulty swallowing, and descending muscular paralysis.
    • African Trypanosomiasis, or sleeping sickness, is caused by two protists and is transmitted by the Tse Tse fly in equatorial Africa, leading to fever, malaise, and eventually coma and death.
    • Primary Amebic Meningoencephalopathy is caused by Acanthamoeba and Naegleria, entering the host through skin abrasions or contaminated water inhalation.
    • Diagnosis of vCJD is based on characteristic signs and symptoms, while rabies is diagnosed postmortem by detecting Negri bodies in the brain.
    • There is no treatment for vCJD, rabies, and primary amebic meningoencephalopathy, but polio is preventable through vaccination.
    • Prevention of these diseases includes avoiding prion-contaminated meat, immunizing pets and people against rabies, and controlling Tse Tse flies to decrease African Trypanosomiasis.
