A recent study found that even mild traumatic brain injuries (TBI) can lead to long-term brain changes in healthy middle-aged adults. 

The research, part of the PREVENT Dementia study, showed that those with a history of mild TBI had detectable brain changes, including cerebral microbleeds, poorer sleep quality, and increased depressive symptoms. 

While cognitive function wasn’t significantly affected, these changes could be early signs of potential neurodegenerative conditions, highlighting the importance of early intervention and preventive strategies.

Lead researcher Dr. Audrey Low speaks with The Wire’s Vanessa Gatica and emphasize the importance of recognizing TBI as a modifiable risk factor for dementia and other neurodegenerative diseases. 

They call for increased awareness and targeted interventions to mitigate the long-term impacts of even mild TBIs in the broader population.

Ruthie's Table 4

Ruthie's Table 4

For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
