A new CAMH study published in the journal JAMA Psychiatry found elevated levels of inflammation in the brain of patients who report persistent symptoms of long COVID.
Using advanced brain scanning with positron emission tomography (PET) imaging agents developed exclusively by the CAMH Brain Health Imaging Centre, study senior author Dr. Jeffrey Meyer and his study team found elevated levels of the protein TSPO, a brain marker of inflammation, in patients with onset of depression within several months after a COVID-19 infection.
“We already knew that there is brain inflammation in people who died in the midst of a severe, active COVID-19 infection. What’s new about this study is that it shows that inflammation is hanging around for a long time in the brains of people with long COVID even after only mild to moderate symptoms of active COVID-19,” said Dr. Meyer, Head of the Neuroimaging Program in Mood & Anxiety at the Campbell Family Mental Health Research Institute at CAMH. “Inflammation in the brain was suspected of being the critical step in causing neurological and psychiatric symptoms of long COVID so confirming this is vital to develop treatments for people experiencing symptoms.”
It is generally believed that the majority of the world’s population has experienced at least one acute episode of COVID-19, and that at least 5 per cent of those people—more than 200 million globally—may experience lingering neurological symptoms, including depression, loss of enjoyment, memory impairment, slower motor control, low motivation and energy, for months to even years due to brain inflammation from long COVID.
As part of this study, 20 participants underwent brain scanning with specialized PET imaging designed to detect the presence of elevated levels of the TSPO protein. All had at least one documented acute episode of COVID-19 after which they reported symptoms of depression that continued for months. Most participants also experienced a variety of other lingering symptoms associated with long COVID, including extreme fatigue and problems with concentration and memory often referred to as ‘brain fog’.
“What’s also noteworthy is that the regions of the brain that had the most inflammation are the ones involved in the capacity to enjoy things, motivational energy and the ability to think and move quickly. These were often the symptoms of greatest concern among the people with long COVID who took part in the study,” added Dr. Meyer.
In a pioneering 2015 study published in JAMA Psychiatry, Dr. Meyer found that the brains of people with depression had more inflammation—30 per cent more on average—than the brains of people who were not depressed. The greater the inflammation, the more severe the depression. It was the first time an association between depression and brain inflammation had been found. This research was so ground-breaking that it became one of the most highly cited international research studies ever produced to date by CAMH.
Dr. Meyer and his team believe that further study of the association between brain inflammation and depression, as well as further study on the short and long-term impacts of COVID-19 on the brain, could lead to new treatments for long COVID that would also be purposed for depression and other illnesses. “For people who have been suffering from long COVID with lingering symptoms of depression, the hope is that we can use anti-inflammatory medications to see if we can get a reduction in symptoms,” said study first author Dr. Joeffre Braga. “Since inflammation can be in response to injury, it might also give us insight into mechanisms of brain injury in neurodegenerative diseases like Parkinson’s and prompt therapeutic development.”
This study was funded by the Canadian Institutes of Health Research (CIHR).

The Key Role of Trustworthy Babysitters in Balancing Work and Family Life
Are you a busy parent in constant pursuit of the elusive work-life balance? We know firsthand how overwhelming and challenging it can be to juggle professional commitments while still having quality time with your children.
That’s why we’re here to discuss an essential ingredient that unlocks the secret to harmony: trustworthy babysitters.
What Characteristics Parents Should Look for When Choosing a Babysitter?
Parents should look for a few key characteristics when choosing a babysitter. A good babysitter should be patient, responsible, and reliable. They should also be comfortable with children and have prior experience caring for them.
Besides, the babysitter must be able to communicate effectively and follow directions well. The babysitter should be someone the parents can trust to care for their children in their absence.
Strategies for Parents to Establish Reasonable Anticipations
As a parent, finding babysitters you can trust to care for your children is vital. However, it is also important to establish reasonable expectations for your babysitters.
Some tips for establishing reasonable expectations for babysitters include:
- Set clear expectations: Sit down with your babysitter to discuss bedtime routines, dietary preferences, and any necessary medications.
- Allow flexibility: While clarity is vital, also provide room for your babysitter to use their judgment and feel comfortable in their role.
- Trust their expertise: Once expectations are set, trust your babysitter’s judgment as a professional caregiver to avoid undermining their authority and creating discomfort in their role.
Determining a Fair Payment Plan
Determine your babysitting budget, factoring in your income and family size, while researching local rates. Account for the babysitter’s experience and qualifications, giving preference to those recommended by trusted sources.
Engage in open negotiations with your chosen babysitter. This aims to find a mutually agreeable arrangement that accommodates both your budget and their needs.
Tips on Finding Trustworthy and Compassionate Caregivers
When seeking a caregiver for your child, to ensure you find the right fit:
- Seek recommendations from trusted sources such as friends, family, and neighbours who may have suggestions for caregivers in your area.
- Conduct online research to review feedback and check references to gauge candidates’ qualifications and experience.
- Request references and contact details from the caregivers’ previous employers or families they have worked with.
- Trust your instincts and ensure you feel at ease with the caregiver, ensuring they are someone you can entrust with your child’s well-being.
Being able to trust your babysitter means you can have peace of mind knowing your child is safe and cared for.
Spending some time researching online reviews or asking friends and family for recommendations will help you find the perfect fit so you can feel more at ease while juggling work commitments in today’s hectic world.
Facility-wide COVID-19 outbreak at Bethammi Nursing Home
THUNDER BAY — St. Joseph’s Care Group and the Thunder Bay District Health Unit have declared a facility-wide COVID-19 outbreak at Bethammi Nursing Home, part of the St. Joseph’s Heritage complex on Carrie Street near Red River Road.
The respiratory outbreak at the 112-bed facility was declared effective Sept. 15 but only announced publicly on Monday.
No details were provided with regard to the number of people affected to date.
Restrictions are now in place for admissions, transfers, discharges, social activities and visitation until further notice.
Alberta COVID hospitalizations up 73% since July: health minister
Three weeks after the start of the school year, Alberta’s health minister provided an update on the spread of airborne viruses in the province.
Adriana LaGrange also said more information about flu and next-generation COVID-19 vaccines will soon be released.
“Now that we will be spending more time indoors, we need to make doubly sure we are following proper hygiene protocols like handwashing and staying home when sick,” LaGrange said. “It also means respecting those who choose to wear a mask.”
Global News previously reported that influenza vaccines will be available on Oct. 16 with the new Moderna vaccine formulated to target the XBB.1.5 variant likely to be available at around the same time. On Sept. 12, Health Canada approved the use of the Moderna vaccine.
“More information on immunizations against respiratory viruses including influenza and COVID-19 will be available shortly,” the health minister said.
LaGrange said there have been 28 cases of influenza and five lab-confirmed cases of respiratory syncytial virus (RSV) since Aug. 28.
“This is consistent activity for this time of the year,” the health minister said in a statement.
The end of August or the beginning of September has typically marked the beginning of flu season for provincial health authorities.
LaGrange also provided an update on the ongoing COVID-19 pandemic in the province.
From Aug. 28 to Sept. 8, there were a total 92 new hospitalizations and three ICU admissions, bringing the total to 417 in hospital and seven in ICU, a 73 per cent increase of COVID hospitalizations from the last reported info.
On July 24 – the last update to the province’s COVID data dashboard – there were only 242 in hospital.
“Sadly, five Albertans died during that period due to COVID-19,” LaGrange said.
LaGrange said the reporting dashboard is being refreshed to include RSV, influenza and COVID-19 data, work that was originally expected to be completed on Aug. 30. The latest data on the province’s influenza statistics dashboard is dated July 22.
“This work is currently underway and will be available in the coming weeks,” LaGrange said.
She said data for the dates between July 24 and Aug. 27 will be available when the new dashboard goes online.
Amid more hospitals continent-wide reinstating masking requirements in the face of increased hospitalizations, the health minister made no mention of any such moves for Alberta hospitals. Acute care COVID-19 outbreaks in Alberta jumped from Sept. 5 to 12, with 146 per cent more healthcare workers and 55 per cent more patients testing positive for COVID.
LaGrange stressed the “collective responsibility” to prevent the spread of airborne viruses like COVID and influenza.
“As a mother and grandmother, I understand the anxiety that comes with sending your children back to school. I want to reassure you that Alberta’s government has the health and well-being of all young Albertans top of mind,” the health minister said.
