Kathmandu: Some people who have been freed from covid infection have complicated neurological problems. Although covid is considered to be a serious respiratory disease, experts say it has caused complex neurological problems in ordinary Nepalis. The nervous system is mainly in the brain and spinal cord. The 12 pairs of nerves coming out of the brain are called 'cranial nerves'.

It travels to the face and neck, while the spinal nerves from the spinal cord travel to the rest of the body, including the limbs, chest, and abdomen. Taste and odor problems, vision problems, stroke, meningitis, Guillain-Barr सि syndrome, and neurological problems affecting the spine. Not only that, from two months to fifteen weeks after recovery, headaches, fatigue, anxiety, dizziness, loss of taste and smell and other problems have been found.

These problems have been identified after analyzing the health condition of 2,679 people who have been admitted to the neurology department of the Tribhuvan University Teaching Hospital for the past one and a half years due to various neurological problems due to covid infection. Ragesh Karna said.

About 50.24 percent of hospitalized covid patients have cranial neuropathy. Dr. According to Karna, the first of the 12 pairs of nerves coming out of the brain, the first pair of nerves, the alpha-factory, carries the odor to the brain, and only then does a person know the odor. But when covid affects the alveolar nerves, odor information does not reach the brain.

Similarly, the second of the cranial nerves, i.e. the 'optic nerve', has been admitted to the hospital. Of those affected, 0.07 percent, or two, had vision problems.

Similarly, blood clotting problems have been seen in the brain of patients who have recovered from covid. This problem can lead to stroke. Of the two types of arterial and venous stroke, 0.52 percent or 14 had arterial stroke and 0.15 percent had venous stroke.

Covid has also been shown to cause meningo encephalitis. This type of fever causes an infection in the lining of the lining that covers the brain. 

In some patients, the taste and smell did not return even after 3 to 6 months of covid. Karna explained. ‘Parkinson’s, dementia is more likely to occur after a long-term odor problem.

Excessive oxygen deprivation in some patients during covid infections can lead to serious side effects, including hypoxic brain injury. Some people have a problem with 'brain fog' and their memory is found to be weak. Karna explained.
