Scientists find brain disorder associated with Zika in adults
A team of scientists in Brazil have said that they have found a new new brain disorder associated with Zikavirusin adults.
The team detected an autoimmune syndrome called acute disseminated encephalomyelitis that attacks a person's brain and spinal cord. The dangerous zika virus is already linked to autoimmune disorder Guillain-Barre syndrome that cause temporary paralysis. The new discovery shows that the Zika may provoke an immune attack on the central nervous system and adds to the increasing concerns over neurological damage associated with the virus.
Dr. Maria Lucia Brito, a neurologist at Restoration Hospital in Recife, Brazil, said in a statement, said, "Though our study is small, it may provide evidence that in this case, the virus has different effects on the brain than those identified in current studies." The acute disseminated encephalomyelitis or ADEM usually happens after an infection and causes swelling in the brain and spinal cord that damages myelin, which is protective coating surrounding nerve fibers. The condition results in weakness, numbness and loss of balance and vision.
The World Health Organisation has said that there is understanding that the virus cause the birth defect microcephaly besides Guillain-Barre but added that concrete evidence might come after several months or even years. The birth defect microcephaly results in unusually small heads for new born babies and results in developmental problems of the child.
Health authorities in Brazil have said that they have confirmed more than 940 cases related to Zika infections in the mothers and is investigating 4,300 additional suspected cases of microcephaly. Some researchers are stating that the virus is causing some patients to get encephalitis and myelitis.
