New Delhi, Nov 21 (PTI) Using a special type of MRI, researchers at the Indian Institute of Technology (IIT) Delhi have uncovered brain changes in patients up to six months after they recovered from COVID-19. Studies have shown that about one in five adults go on to develop long-term effects from COVID-19.

Neurological symptoms associated with long COVID include difficulty thinking or concentrating, headache, sleep problems, lightheadedness, pins-and-needles sensation, change in smell or taste, and depression or anxiety.

However, studies have found that COVID-19 may be associated with changes to the heart, lungs or other organs even in asymptomatic patients. The latest study, being presented next week at the annual meeting of the Radiological Society of North America (RSNA), used susceptibility-weighted imaging to analyse the effects that COVID-19 has on the brain.
