A new potential cause of Alzheimer’s disease has been discovered and could lead to a cure. A study of Alzheimer’s in mice at Duke University, North Carolina, has led to the discovery the disease is connected to the immune cells that normally protect the brain. However, with Alzheimer’s the cell consume vital nutrients called arginine, causing memory loss. The study showed that this process could be blocked, and thereby prevent the formation of ‘plaques’ in the brain that are characteristics of Alzheimer’s disease. The study halted memory loss in the mice.

A poll showed that 34 percent of GPs are planning to retire within the next five years. The main reasons were high stress levels, the workload, and the little time spent with each patient. The poll conducted by the British Medical Association, also showed that 1 in 10 GPs are considering working abroad, while 17 percent would like to work part-time, and 7 percent are considering quitting medicine completely.

A new study indicates that fathers’ sperm may hold the trigger to autism in their children. The study analysed sperms from 44 fathers of babies who showed early signs of autistic symptoms, and the scientists found that the changes in the epigenetics in the men’s DNA could transfer autism to the next generation. The Epigenetic changes which involve modifications in chemicals attached to the DNA molecule have been linked with irregular development of the nerve cells in the brain.
