This was because VTA activation subdued cells in the bone marrow that would usually repress immune activity, freeing the immune system to fight cancer.Īnother area of research is focused on using virtual reality to manipulate people’s stress levels and see how it changes the immune response.

In a recent experiment, activation of neurons in the VTA reduced the size of lung and skin tumours in mice.

Conversely, studies have also suggested that a positive mindset can lead to better outcomes in cardiovascular disease patients.Īdditionally, their work is also investigating the impact of the brain on cancer treatment. The phenomenon is well-known in the condition known as ‘broken-heart syndrome’, where an extremely stressful event can cause the symptoms of a heart attack. Their work is inspired by decades of research pointing to the contribution of a person’s psychological state to their heart health. Haykin is part of a growing group of scientists who are exploring the brain’s control over the body’s immune responses. By triggering immune changes, the activation of the brain’s reward centre called the ventral tegmental area (VTA), reduces scar tissue and promotes healing. Her experiments, conducted on mice, show that stimulation of a brain region involved in positive emotion and motivation can influence how the heart heals after a heart attack. Hedva Haykin, a doctoral student at the Technion - Israel Institute of Technology in Haifa, is at the forefront of this research. Recent studies in the field of neuroimmunology are revealing a close relationship between our brain and our immune system, and how our mental state can affect our bodily responses to illness and disease. The Surprising Connection Between Your Brain and Physical Illness How the Brain Induces Symptoms of Sickness.

The Surprising Connection Between Your Brain and Physical Illness.

Our brains play a crucial role in our overall health, and when things go wrong in the brain, it can lead to physical symptoms and illnesses. This is because the brain and body are connected by a complex network of nerves and hormones, and when the brain sends signals of stress, the body responds by releasing stress hormones that can damage our health over time. Chronic stress, anxiety, and depression can lead to long-term health problems, such as heart disease, high blood pressure, and weakened immune systems. But it’s not just temporary symptoms that our brains can cause. For example, have you ever felt a knot in your stomach when you’re nervous or stressed? Or how about getting a headache when you’re feeling overwhelmed or upset? These are just a few examples of how our mental state can impact our physical health. It’s a well-known fact that our thoughts and emotions can affect our bodies.

Let’s explore the strange question of can your brain make you ill? Normally, when we think of getting sick, we think of it as viruses and bacteria from the outside world getting into our bodies, however, there are occasions when this isn’t the only way that we can get sick.
