Inside the Mind: How Long COVID Affects Brain Function


United States – Strokes in the brainstem may be attributed to the physical and psychological manifestations of Long COVID, according to a new study.

Thirty Long COVID patients had MRI scans, which showed for the first time that damage was done to a part of the brainstem that controls symptoms like breathlessness, fatigue, and anxiety, as reported in the Brain journal on Oct 7, as reported by HealthDay.

Understanding the Role of the Brainstem

“The brainstem is the critical junction box between our conscious selves and what is happening in our bodies,” said co-lead researcher James Rowe, a senior research fellow with the University of Cambridge Department of Clinical Neurosciences. “The ability to see and understand how the brainstem changes in response to COVID-19 will help explain and treat the long-term effects more effectively.”

Autopsies of individuals who succumbed to severe COVID-19 in its early phase revealed alterations in the brainstem, researchers noted in background information.

Inflammatory Damage from COVID-19

“People who were very sick early in the pandemic showed long-lasting brain changes, likely caused by an immune response to the virus. But measuring that immune response is difficult in living people,” Rowe said. “Normal hospital-type MRI scanners can’t see inside the brain with the kind of chemical and physical detail we need.”

Thus, the research team used stronger MRI machines called 7-Tesla scanners and established that COVID infection resulted in inflammation damage in several areas of the brainstem.

These abnormalities arose several weeks after admission to the hospital, usually in areas of the brain governing respiratory functions, the scientists clarified.

Connection Between Physical and Mental Health

“The fact that we see abnormalities in the parts of the brain associated with breathing strongly suggests that long-lasting symptoms are an effect of inflammation in the brainstem following COVID-19 infection,” said co-lead researcher Dr. Catarina Rua, a postdoctoral researcher with the University of Cambridge. “These effects are over and above the effects of age and gender and are more pronounced in those with severe COVID-19.”

The brain scans also showed damage in areas related to fatigue and anxiety, researchers said, as reported by HealthDay.

“Mental health is intimately connected to brain health, and patients with the most marked immune response also showed higher levels of depression and anxiety,” Rowe said in a Cambridge news release. “Changes in the brainstem caused by COVID-19 infection could also lead to poor mental health outcomes because of the tight connection between physical and mental health.”

United States: Black parents with teenagers with autism have concerns about their children’s vulnerability when they encounter police officers.

Key Findings from the Study

A study published on Dec. 16 in the Autism Journal has revealed that aspects like reduced eye contact observed in children with autism may make police consider them to be guilty, as reported by HealthDay.

Sadly, police officers do not learn that these actions are typical among children with autism, families informed scholars.

Voices of the Researchers

“It’s important for everyone to understand that the parents in this study said they were hopeful, which we interpreted as Black caregivers’ faith that interactions between officers and Black autistic youth could be better,” said lead researcher Ashlee Yates Flanagan, a clinical psychologist at the Children’s Hospital of Philadelphia Center (CHOP) for Autism Research.

“This demonstrates that there’s space for improvement in training, and we can take what we know from this study and explore it further,” Flanagan added in a CHOP news release.

During the interviews, four distinct themes surfaced:

  • The caliber of police officer education
  • Inappropriate police enforcement of typical autistic behaviors
  • The overt threat of injury and death
  • Families believe that police officers may become aggressive towards gestures and responses that are normal for AS children but not for other children, as the study indicated.

Some families said that training might make police see these differences in conduct, which should bring about tolerance and perseverance that could enhance the relations between children and the police.

“In this study, we captured rich narratives from stakeholders who have not been represented well in prior research, but whose thoughts and perspectives are critical for knowing how to improve outcomes for Black autistic youth and police,” said senior researcher Julia Parish-Morris, a scientist in the CHOP Center for Autism Research, as reported by HealthDay.

“Our findings suggest that there is a lot of room for growth in training for police officers and that Black parents of Black autistic youth carry hope that outcomes can be improved,” Parish-Morris added.

AI Breakthrough Simplifies Lung Disease Testing

This AI breakthrough promises faster, more accessible, and cost-effective COPD diagnosis with a single CT scan.

United States: Research says that people with breathing problems can know whether they are suffering from COPD with the help of a new lung AI test.

AI Offers a One-Scan Solution for COPD

The newly developed AI can accurately diagnose COPD using data from a single chest CT scan performed as a person inhales, researchers reported Dec. 12 in the journal Radiology: Cardiothoracic Imaging, as reported by HealthDay.

The researchers said it can also inform from that scan how severe a person’s COPD is.

So far, doctors have required two CT scans to diagnose and assess COPD — one when the person has taken a deep breath and one when he or she has exhaled.

“Our study shows that COPD diagnosis and staging is feasible with a single CT acquisition and relevant clinical data,” said researcher Kyle Hasenstab, an assistant statistics and data science professor at San Diego State University.

A Growing Global Health Concern

COPD is defined as a systemic group of lung diseases that become worse over time and make it difficult for individuals in the community to breathe. COPD is chronic, and there is no known treatment for the disease, although it ranks third in deaths globally, according to the researchers’ background information.

The researchers added that spirometry, a lung function test that tests the amount of air, including vital capacity, that a patient can inhale and exhale, has been the primary approach toward identifying COPD.

Some hospitals already use CT images of the lungs to help diagnose COPD because the images can point out lung tissue that might be limiting breath, Hasenstab said.

“However, this type of protocol is not clinically standard across institutions,” Hasenstab said; this is due to the fact that it requires additional training for the staff to be able to take good CT images as well as to be able to interpret them.

Scientists believed that if the AI could read CT scans for COPD, more people could be provided with CT scans, despite a lack of training.

How the AI Works

To provide answers for this study, the researchers captured the inhaled and expelled lung CT scans of nearly 8,900 patients who were tested from November 2007 to April 2011 and their spirometry results.

The average age of patients was 59, and all patients were smokers.

Benefits of the AI Tool

The team then utilized the CT scans and the clinical data to teach the AI to forecast spirometry outcomes.

Study findings indicated that the AI could identify COPD by relying on one of the CT scans and could reasonably express how severe the COPD had become.

Researchers pointed out that when they introduced clinical data, the accuracy of the AI was enhanced.

Visual Representation.

Researchers also discovered that the AI’s performance was similar when the patients had to hold their breath during the CT scan or when they were breathing normally, as reported by HealthDay.

“Reduction to a single inspiratory CT acquisition can increase accessibility to this diagnostic approach while reducing patient cost, discomfort, and exposure to ionizing radiation,” Hasenstab said in a journal news release.

Screen Time Wrecks Preschoolers’ Sleep and Behavior

Excessive screen time disrupts preschoolers’ sleep and behavior, underscoring the need for controlled device usage and better sleep habits.

Screen Time Wrecks Preschoolers’ Sleep and Behavior


United States: Excessive use of electronic devices threatens preschoolers’ sleep and urges the child to become a terror of the house, new research shows.

Screen Time and Sleep: A Vicious Cycle

Researchers said poor sleep worsens children’s ability to focus and be less hyperactive and moody, as published in Early Child Development and Care on 12th December.

Worse still, cylinders can occur where kids spend a lot of time in front of screens, leading to poor sleeping habits and consequently increased screen time, as reported hy HealthDay.

“Our results suggest the presence of a positive feedback loop, wherein increased screen time and sleep disturbances exacerbate each other through cyclic reinforcement, heightening the risk of hyperactive attention problems, anxiety, and depression,” said researcher Dr. Bowen Xiao, an expert in children’s socio-emotional functioning and developmental psychopathology with Carleton University in Canada.

The Research: Insights from Parents

To gather data, the authors administered questionnaires to the 571 mothers of preschool children aged between 3 and 6 years attending seven public kindergartens in Shanghai.

Moms recorded the number of daily hours their children spent with a TV, smartphone, computer, or any other screen-based device. They also asked them questions to determine any possible behavioral issues that their kids may have, as well as the quality and duration of sleep their children get.

“Our results indicate that excessive screen time can leave the brains of preschool children in an excited state, leading to poor sleep quality and duration,” said researcher Yan Li, an expert in preschool education from Shanghai Normal University.

Researchers also pointed out that other studies have shown that children’s screen use can cause emotional issues and hyperactivity.

According to this study, screen time may be the cause, according to the experts.

Screen Time’s Impact on Sleep

“This poor sleep may be due to postponed bedtimes caused by screen viewing and the disruption of sleep patterns due to overstimulation and blue-light exposure,” added lead author Shujin Zhou, a doctor of psychology at Shanghai Normal University.

“Screen use might also displace time that could have been spent sleeping and increase levels of physiological and psychological arousal, leading to difficulties in falling asleep,” Zhou said in a journal news release.

Therapeutic Implications

According to Zhou, these findings may help guide future therapies for young children’s mood and hyperactivity issues.

“The implications of our study are two-fold: first, controlling screen use in preschool-age children can help alleviate behavioral problems and poor sleep quality, and second, sleep interventions and treatments can be effective in mitigating the adverse effects of screen time on behavioral issues,” Zhou noted, as reported hy HealthDay.
