Researchers have discovered a blood test that can accurately predict the onset of dementia, including Alzheimer’s disease. The test detects “biomarkers” in the blood that, if found, can determine if someone will develop Alzheimer’s disease within three years.
Scientists from Georgetown University Medical Centre monitored 525 healthy participants aged 70+ over five years. They compared blood samples from 53 participants who developed dementia to “cognitively normal” people.
Neuroscientists have made an unexpected discovery that brings new meaning to the term “brainwash.”
In a study of mice, researchers found that the brains of awake mice were dry, whereas the brains of sleeping mice were full of fluid.
When mice fell asleep under the microscope, “It was almost like you opened a faucet,” said lead researcher Maiken Nedergaard.
The cerebrospinal fluid increased in volume by at least 60% during sleep. The benefit of the extra fluid? It washed away unwanted debris.
