Causes of Dawson's encephalitis:
1. The measles virus causes Dawson's encephalitis, a deadly, degenerative condition of the central nervous system. Myoclonic seizures, increasing neurologic deficiency, and gradual intellectual and personality abnormalities may all be present in a patient's clinical history over the course of many weeks.
2. A sluggish measles virus is believed to be the cause of Dawson's encephalitis (paramyxovirus). Slow viruses can slumber in humans for a long time before becoming active again for reasons that are still unknown. It is unclear how inheritance affects a person's susceptibility to slow viruses.
3. Many years after the initial sickness, the virus may reactivate and cause new symptoms, such as brain inflammation (encephalitis) and the loss of the fatty layer on nerve fibers (demyelination). Additionally, it might be linked to an improper immunological response to the rubeola virus (measles). Usually, 2 to 10 years before the development of subacute sclerosing panencephalitis, the affected person has measles.
4. A few cases of subacute sclerosing panencephalitis have been linked to animal contact in the medical literature. These affected people interacted with pets like dogs, cats, or monkeys who later passed away from the same ailment.
