Gizmodo reports certain bacteria spread by cat scratches and other animal exposures can sometimes have a dramatic impact on the brain. A new study profiles a group of patients with psychiatric illness who simultaneously showed signs of infection from bacteria called Bartonella. Bartonella bacteria aren’t usually linked to serious illness in people. But certain groups, like those immunocompromised, might be more vulnerable generally. The rod-shaped Bartonella bacteria can survive and replicate inside other cells, much like viruses. This ability allows them to evade conventional tests for detecting infection and makes it harder for antibiotics to kill them. Bartonella henselae is the most commonly seen infection in humans and causes cat scratch disease--also called cat scratch fever. Despite the name, B. henselae and other disease-causing Bartonella can be spread through dogs and other mammals, and parasites like ticks, fleas, and lice. I
A new study has identified a link between stress hormones and the recurrence of cancer. UPI reports the findings may explain why cancers can return long after seemingly being cured with chemotherapy or surgery. The study showed stress hormones and immune cells called neutrophils may awaken dormant cancer cells and cause tumors to regrow -- even after treatment -- according to a study published Wednesday by Science Translational Medicine. Tumor recurrence may be facilitated by common stress. Study co-author Dr. Dmitry Gabrilovich Chief Scientist, AstraZeneca Stress hormones such as cortisol have been linked with an increased risk for a number of health problems. Elevated levels of these hormones can increase a person's heart rate and lead to rises in blood pressure. Because of this, it can lead to insomnia, robbing the body of needed sleep, and mental health disorders such as anxiety and depression.
COVID-19 already has been linked to an assortment of alarming long-term physical health effects. Now a new study illuminates what the virus can also do to a person’s brain, says HuffPost. Those diagnosed with COVID-19 are at a greater risk of developing mental health disorders. The data shows 1 in 5 surviving patients will get a mental health diagnosis within roughly three months of infection. The most common conditions experts have seen include PTSD, anxiety, and depression. Other conditions that have been found are insomnia and dementia.
