Dementia is a brain disease that usually strikes people after the age of 65. There are almost 50 million people around the world who suffer from this disease, and each day, that number increases. According to forecasts, by the year 2030, that number will reach 75 million, and 131.5 million in 2050. One of the reasons is that their relatives don’t consult a doctor in time. By the way, the first signs occur 5-10 years before the disease develops completely. If you notice them and send this person to a doctor, this could help to prolong their normal life.
