Long covid infection linked with risk of 'face blindness', warns new study

New Delhi, Mar 21: Prolonged symptoms of Covid-19 may be associated with difficulty recognising faces, a little-known condition called face blindness, and navigational problems, according to a study.

Previous studies have shown that Covid-19 can cause a range of neurological problems, including the loss of smell and taste, and impairments in attention, memory, speech, and language, known as "brain fog".

The latest research, published in the journal Cortex, is the first to report prosopagnosia, or face blindness, following symptoms consistent with Covid-19.

The condition that can make people fail to recognise familiar faces, has been estimated to affect between 2 and 2.5 per cent of people in the world.

The researchers assessed the case of Annie, a 28-year-old customer service representative and part-time portrait artist in the US, who was diagnosed with Covid-19 in March 2020 and suffered a symptom relapse two months later.

"When I first met Annie, she told me that she was unable to recognise the faces of her family," said Marie-Luise Kieseler, a graduate student at Dartmouth College in the US, adding Annie now relies on voices to recognise people.

Annie also experienced navigational deficits after having Covid-19. She has had difficulty remembering where particular sections in her grocery store are and relies on Google maps and its pin function to remember where she parks her car.

“The combination of prosopagnosia and navigational deficits that Annie had is something that caught our attention because the two deficits often go hand in hand after somebody either has had brain damage or developmental deficits,” said study senior author Brad Duchaine, a professor at Dartmouth.

"That co-occurrence is probably due to the two abilities depending on neighbouring brain regions in the temporal lobe," Duchaine said in a statement.

Dr. Vinit Suri, Senior Consultant, Neurology, Indraprastha Apollo Hospitals, New Delhi noted that the exact mechanisms by which long Covid may cause face blindness are not yet fully understood, but there are several possible explanations.

"Firstly, long Covid can cause a range of neurological symptoms which may affect the brain regions responsible for face recognition, causing difficulty in processing visual information and recognising familiar faces," Suri told PTI.

"Secondly, Covid-19 can cause inflammation and damage to the blood vessels, which can lead to reduced blood flow to the brain. This can cause brain damage and cognitive impairments, including face blindness," he added.

The research team conducted a series of tests with Annie to evaluate her problems with face recognition and determine whether she also has difficulties with other perceptual or cognitive abilities.

In one test, Annie was sequentially presented with 60 images of celebrity faces and was asked to name them. Annie correctly identified 29 per cent of the 48 celebrities whom she was familiar with as compared to most people, who can correctly identify 84 per cent of familiar celebrities.

The second test was a doppelganger test. Annie was shown a celebrity's name and then presented with images of two faces: the face of a celebrity and that of someone similar, and was then asked to identify which face was the famous person.

She identified the celebrity in 69 per cent of the 58 trials, as compared to 87 per cent in the control group.

"Our results from the test with unfamiliar faces show that it wasn't just that Annie couldn’t recall the name or biographical information of a famous person that she was familiar with, but she really has trouble learning new identities," said Kieseler.

The research team also obtained self-reported data from 54 individuals who had long Covid with symptoms for 12 weeks or more, and 32 persons who had reported that they had fully recovered from Covid-19.

Most respondents with long Covid reported that their cognitive and perceptual abilities had decreased since they had Covid.

"It was not just a small concentration of really impaired cases but a broad majority of people in the long Covid group reported noticeable difficulties doing things that they were able to do before contracting Covid-19 without any problems," Kieseler said.

"Our study highlights the sorts of perceptual problems with face recognition and navigation that can be caused by Covid-19 -- it is something that people should be aware of, especially physicians and other health care professionals,” Duchaine added.

Dr. Atul Prasad, Principal Director & HOD Neurology, BLK-Max Super Speciality Hospital, New Delhi said this is the first report of long Covid causing prosopagnosia.

"The more we study the virus, the more we realise how much damage it can cause during acute infection and now after infection has settled," Prasad told PTI.

Suri noted that that not all people with long Covid will develop face blindness, and the severity and duration of symptoms can vary widely.

"Further research is needed to better understand the relationship between long Covid and face blindness and to develop effective treatments and interventions for those affected," he added.

Mangaluru: A routine midnight tea run turned into a horrifying tragedy when a motorcycle carrying three young men — in clear violation of traffic rules — slammed into an open divider on National Highway 66 at SKS Junction in the early hours of April 8. Two of them lost their lives, while the third is recovering from injuries.

The victims have been identified as Sankeerth, who was riding the motorcycle (KL-58-Q-6381), and Dhanurved C, the first pillion rider. Sibi Sam, the second pillion rider, was injured but survived the crash.

According to the FIR registered at the Traffic East Police Station (Crime No. 48/2025), the friends had set out from Lohith Nagar around 2:30 am, heading towards Pumpwell for tea. While Rohan Joby and Meghnath rode separately on a different bike (KL-13-AH-2388), Sankeerth was accompanied by two pillion riders — a clear case of triple riding, which is both illegal and dangerous.

As they sped along NH-66, Sankeerth reportedly lost control near SKS Junction and collided with the edge of an open road divider at approximately 2:50 am. The impact threw all three men onto the highway with violent force.

Sankeerth and Dhanurved suffered critical head and facial injuries and died while being rushed to the hospital. Sibi Sam is undergoing treatment for his injuries.

The FIR invokes Sections 281, 125(a), 106(1) of the Bharatiya Nyaya Sanhita, and 128(a) read with 177 of the Motor Vehicles Act, which include provisions related to rash driving and traffic violations.

The police have launched a full investigation. The accident has reignited public concern about reckless driving, triple riding, and the hazards posed by poorly maintained road dividers, especially during low-visibility hours.

Mangaluru, Apr 7: A price storm is brewing in Mangaluru’s hotel and restaurant industry. Faced with skyrocketing raw material costs and mounting overheads, hoteliers are preparing to hike food prices by up to 10% within a month — a move that could hit the pockets of thousands of diners across Dakshina Kannada.

From milk and oil to LPG and staples like rice and toor dal, prices have surged, pushing both vegetarian and non-vegetarian establishments to the brink. Over 65% of hotels operate in rented spaces, and labour shortages are adding fuel to the fire.

Swarna Sunder of Dinki Dine says running a hotel without burdening customers is becoming near-impossible. “Costs are rising daily. We’re trying to strike a balance, but a hike is inevitable,” he said, calling Mangaluru a highly price-sensitive market.

Industry leaders, including the Dakshina Kannada Hotel Owners Association, are expected to meet soon to formalize the revision.

Meanwhile, hoteliers blame "unhealthy competition" for further disrupting the sector. “Some serve unlimited fish meals under ₹60 — it’s unsustainable and unfair,” said a hotelier, adding that such practices are forcing smaller eateries to shut shop.

Chandrahas Shetty, president of the district association, confirmed that rising input costs have left them with little choice but to revise menus.

Mangaluru, Apr 7: The long-standing demand for a separate Beary Development Corporation has hit a wall — the Karnataka government has officially stated that no such proposal is currently under consideration.

Beary-speaking people, mainly settled across Dakshina Kannada, Udupi, and parts of Kodagu, have been urging the government to set up a dedicated body for the welfare of their community and the promotion of their unique 1,200-year-old language. But during the recent legislative session, Minority Affairs Minister B.Z. Zameer Ahmed Khan confirmed that his department has not received any proposal on this matter.

The clarification came in response to a question by MLC Ivan D’Souza, who highlighted the community’s cultural richness and a population of over 25 lakh. “The community has raised this demand several times to support education and social upliftment, but the government hasn’t taken any concrete steps,” he said.

In his reply, the minister pointed out that the Karnataka Minorities Development Corporation (KMDC) already runs various welfare schemes for Muslim, Christian, Jain, Buddhist, Sikh, and Parsi communities. Since Beary speakers are considered part of the Muslim community, they are eligible for benefits under these existing programs, he added.

Still, many in the Beary community feel that without a separate development body, their identity, language, and specific needs risk being overlooked.
