— by Isabel GodfreyNeurons die earlier than experts previously thought in Alzheimer’s disease, and stopping the process could prevent the disease from ever developing, finds a new study from Tokyo Medical and Dental University in Japan.Alzheimer’s disease is the leading cause of dementia, and as many as people in the United States live with the disease. It causes a range of symptoms that begin with memory loss and confusion before progressing to difficulties with orientation, thinking, and speech. There is currently no cure for Alzheimer’s, and the exact cause of the disease remains...…— by Isabel GodfreyNeurons die earlier than experts previously thought in Alzheimer’s disease, and stopping the process could prevent the disease from ever developing, finds a new study from Tokyo Medical and Dental University in Japan.Alzheimer’s disease is the leading cause of dementia, and as many as people in the United States live with the disease.

A key factor that will determine how soon life can return to normal after the pandemic is how easily people can reacquire SARS-CoV-2, which is the virus that causes COVID-19.Proven cases of reinfection have been extremely rare, but the most comprehensive population-based study to date suggests that the risks may be greater than scientists initially thought.The study, which drew from a register of millions of polymerase chain reaction (PCR) tests...…— by Hannah Flynn, MSAll data and statistics are based on publicly available data at the time of publication.
