Abstract:

It is increasingly evident that bidirectional interactions exist among the gastrointestinal tract, the enteric nervous system, and the central nervous system. Recent preclinical and clinical trials have shown that gut microbiota plays an important role in these gut-brain interactions. Furthermore, alterations in gut microbiota composition may be associated with changes in various neurological and psychological conditions, including stress, autism, and depression. Therefore, the concepts of the microbiota-gut-brain axis are emerging. Here, we review the role of gut microbiota in bidirectional interactions between the gut and the brain, including neural, immune-mediated, and metabolic mechanisms. We highlight recent advances in the understanding of probiotic influences on neurological and neuropsychiatric function via the gut-brain axis.

Cardiovascular Inflammation: A Silent Risk to Heart and Brain

Rapid changes in temperature, such as moving between extreme heat and cold or frequent exposure to air conditioning, place stress on the body’s regulatory systems.

The brain plays a central role in thermoregulation, helping the body maintain a stable internal temperature.

Christmas is a joyful time for many, often marked by changes in routine. While these moments are meant to be enjoyed, repeated excesses can be associated with low-grade inflammation, a natural immune response that, when prolonged, may influence digestion, energy levels, mood, and overall gut health.

Chronic inflammation is a factor associated with a range of health conditions, from digestive imbalances to changes in cognitive function.

Every year, as Black Friday approaches, inboxes overflow, wish lists grow, and our brains enter a state of heightened stimulation.

Inflammation is a vital part of the body’s immune defense, but when it becomes chronic, it can affect healthy cells and is associated with conditions such as cardiovascular disease, metabolic disorders, and changes in brain health.

Over 3 million Americans live with Inflammatory Bowel Disease (IBD), a group of chronic conditions that includes Crohn’s disease and ulcerative colitis.

Memory lapses happen to everyone from time to time. But when forgetfulness or confusion becomes consistent, it may signal underlying changes in cognitive function.

We often think of the five senses as the only ways we experience the world: sight, hearing, smell, taste, and touch.

Music is more than just entertainment. From lifting our spirits to helping us focus, music engages the brain in powerful ways.

Breakfast has long been called the “most important meal of the day.” But is it really that essential for your brain health or just an old saying?

Most people think missing a few nights of sleep isn’t a big deal. But neuroscience suggests otherwise. Even a single week of poor sleep can affect memory, mood, and cognitive performance, and over time may be associated with changes in long-term brain health.

Alcohol dampens the brain’s control systems, particularly the prefrontal cortex, the region responsible for judgment, self-regulation, and long-term decision-making.

Halloween may come once a year, but for your brain and gut, sugar overload can have noticeable effects. While a few sweets are harmless, regularly consuming high amounts of sugar can disrupt your gut microbiota, increase inflammation, and affect cognitive performance.

For many of us, the day doesn’t truly start until we’ve had that first sip of coffee. But beyond the morning ritual, how does coffee actually affect your brain, gut, and overall well-being?

We often hear that “sleep is the best medicine,” but science now shows just how true this may be, especially for the brain. Sleep is not only a time for rest; it is a highly active process that clears waste, consolidates memories, and restores balance in the nervous system.

When someone experiences changes in memory and cognitive function over time, it is expected that tasks like recall, organization, and daily routines may become more challenging.
