Covid-19 may affect brain, trigger neurological problems, says doctor

COVID-19 may have been viewed and treated primarily as a respiratory illness, but it is more sinister and pervasive in its impact on the human body as it may affect the brain thereby accelerate or trigger neurodegenerative diseases such as Alzheimer's and Parkinson's, according to a doctor. Describing the pandemic as 'a beast with a thousand heads', Dr Yatish Agarwal, senior professor, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, says the effect of the COVID-19 extends far beyond the nose, throat, and lungs and may infect the brain, the most vital bodily organ. Vast clinical studies reveal that neurological complications occur in 36-84 per cent of COVID-19 patients. Strangely, many people who experience neurologic symptoms that linger after the disease are less than 50 years old and were healthy prior to the infection, he points out in an exclusive article for Manorama Yearbook 2023. Panic attacks, obsessive compulsive disorder and depression can occur among

Covid-19 infection increases risk of long-term brain problems: Study

People infected with the SARS-CoV-2 virus are at increased risk of developing a range of neurological conditions in the first year after the infection, according to a large study conducted in the US. Such complications include strokes, cognitive and memory problems, depression, anxiety and migraine headaches, the researchers said. The researchers at Washington University School of Medicine also found that the post-COVID brain is associated with movement disorders, from tremors and involuntary muscle contractions to epileptic seizures, hearing and vision abnormalities. The infection is also associated with balance and coordination difficulties as well as other symptoms similar to what is experienced with Parkinson's disease, they said. "Our study provides a comprehensive assessment of the long-term neurologic consequences of COVID-19," said Ziyad Al-Aly from Washington University. "The results show the devastating long-term effects of COVID-19. These are part and parcel of long COV

IBS hospital launches brain mapping device, claims it is first of its kind

Combining research with cutting-edge technology, a Delhi-based hospital on Sunday launched a "brain mapping device" and claimed it was the first-of-its-kind gadget in the country. With the advent of such personalised brain mapping, treatment for brain tumour and other brain surgeries have become much safer and due to the accuracy, damage to important brain areas can be avoided, it said in a statement. "In a first-of-its-kind technology to be launched, with combination of decades of research with cutting edge technology, IBS Hospitals today launched first brain mapping device connectomics/ quicktome in the country," the private hospital claimed. Quicktome uses sophisticated algorithms to analyse millions of data points and build a brain map personalised to each patient from a standard, non-invasive MRI scan. The maps, which doctors can view on their computers, offer a level of anatomical detail typically not available in a clinical setting, allowing surgeons to incorporate advance
