First, we like to introduce with this disease 'Dementia' is a group of conditions which is characterized by impairment of at least two brain functions, which are memory loss and judgment. Signs include this disease is forgetfulness, limited social skills, and thinking abilities so impaired that it interferes with daily functioning. Medication and therapies may help manage symptoms. Some causes are reversible.

And according to the new research using Google often to search for information and other sources rather than using our brains, may raise the risk of dementia, a UK researcher has suggested. The researcher has defined the practice as an "experiment". 

"It's necessary to support good brain health and to do that is to use it, but in today's time our brain to the internet," stated by Frank Gunn-Moore, from the University of St Andrews in the UK. "Its an experiment the human race is running and we will have to wait and see if this outsourcing affects dementia prevalence," he told.

Gun-Moore will be talking at the annual Alzheimer Scotland Christmas event in Edinburgh on December 14."There are many factors that could result in Alzheimer's it can be an environment, stress on the brain, genetics," he replied.In 2015, the number of people with dementia reached almost 45 million, two times more than in 1990, according to a rough estimate.
