 World Alzheimer’s Day will be observed on September 21 all over the world including Pakistan to raise awareness about Alzheimer’s and dementia.Alzheimer’s disease is the most common form of dementia, a group of disorders that impairs mental functioning. At the moment, Alzheimer’s is progressive and irreversible. Every 71 seconds, someone develops Alzheimer’s disease. Today, it is estimated that about five million Americans and 30 million people worldwide suffer from Alzheimer’s disease. In the US, about 360,000 people are newly diagnosed every year. Alzheimer’s affects about 10 percent of people ages 65 and up, and the prevalence doubles roughly every 10 years after age 65. Half of the population ages 85 and up may have Alzheimer’s. Because the population of the US is aging, the number of people with Alzheimer’s will continue to rise unless something can be done to stem the disease. At current rates, experts believe that as many as 16 million Americans will have the disease by the year 2050. The theme for World Alzheimer’s Day 2011 is ‘Faces of dementia’. Alzheimer’s Disease International has launched the “World Alzheimer Report 2011″ that shows that there are interventions that are effective in the early stages of dementia, some of which may be more effective when started earlier, and that there is a strong economic argument in favour of earlier diagnosis and timely intervention. Dementia diagnosis provides access to a pathway of evidence- based treatment, care and support across the disease course. Perhaps as many as 28 million of the world’s 36 million people with dementia have yet to receive a diagnosis, and therefore do not have access to treatment, information, and care. Available evidence suggests that governments should `spend to save’ in other words, invest now to save in the future. Economic models suggest that the costs associated with an earlier dementia diagnosis are more than offset by the cost savings from the benefits of anti-dementia drugs and caregiver interventions. These benefits include delayed institutionalisation and enhanced quality of life of people with dementia and their carers.
