The World Health Organisation (WHO) has announced that COVID-19 is no longer a public health emergency of international concern (Pheic). This declaration marks the end of the emergency response period that began in January 2020. The WHO has also unveiled a new strategy to transition from an emergency response to longer-term sustained COVID-19 disease management.

The blood-brain barrier is a protective shield that prevents toxins and pathogens from entering the brain. However, it also hinders the effectiveness of drugs designed to help treat brain cancer. For years, scientists have been searching for ways to overcome this barrier and deliver medications to the brain. In 2014, researchers discovered a method of

Nightmares are a common problem that affects many people. Not only do they disturb sleep, but they are also linked to other health issues such as anxiety and poor-quality sleep. Researchers have been investigating ways to help reduce the frequency and severity of nightmares, and a recent study suggests that non-invasive techniques can help manipulate

Glioblastoma is a malignant brain tumor known for its aggressiveness and difficulty to treat. However, a new hydrogel treatment has shown promising results in eliminating glioblastoma tumors in mice. The Hydrogel Treatment The hydrogel treatment uses paclitaxel, a chemotherapy drug, to create nano-sized filaments for insertion into the brain. The hydrogel covers the cancer cavity

Researchers at North Carolina State University (NCSU) have discovered that senior dogs with cognitive decline experience disruptions similar to those found in people with Alzheimer’s disease. This study suggests that dogs could provide a good model for research on Alzheimer’s. The Study The researchers recorded the brain waves of 28 senior dogs, some with cognitive

An international team of researchers conducted a five-year study of 647 Danish babies to learn more about the viral makeup of the human gut. Astonishingly, nappy samples contained approximately 10,000 species of virus, which is ten times the number of bacterial species found in the same children. Most of the viruses had never been described

A team of surgeons from two US hospitals have successfully repaired a major malformation in a fetal brain. The surgery, which was guided by ultrasound and involved embolization, treated a rare prenatal condition known as vein of Galen malformation. This condition allows blood to flow dangerously fast through the brain after birth. The successful procedure

Alzheimer’s treatments have experienced a revival, with pharma giant Eli Lilly announcing that its experimental drug donanemab has successfully slowed cognitive and functional decline in patients with early-stage Alzheimer’s. Although neither donanemab nor a similar drug called Leqembi amount to a cure for Alzheimer’s, which affects around 6.5 million Americans, Wall Street analysts estimate that

Dementia is a brain disease that affects approximately 55 million people worldwide, leading to the loss of cognitive functions. While early signs of dementia may be subtle, researchers have identified other noticeable changes to the body that can indicate dementia risk. A recent study suggests that hearing difficulties may be a warning sign of dementia

New research has shown that significant changes in gut microbiota happen in the early stages of Parkinson’s disease and can begin before the onset of symptoms. Scientists from China and Germany studied the bacteria in the guts of individuals with early Parkinson’s disease, REM sleep behavior disorder (RBD), their close relatives, and healthy people. The
