Updated September 30, 2018 10:16:38 The cause of dementia is still unknown, but there is growing evidence that Alzheimer’s and other dementias can be caused by changes in the brain, according to a new study.
Key points:Researchers found that changes in brain function can lead to dementiaScientists have found changes in how brain function affects memory, making it more likely to occurThe study was published in the journal Neurology.
Researchers from the University of Oxford found that brain changes in older people can make it more difficult for them to remember things, which could explain the link between dementia and memory loss.
The team looked at the brains of people who had been diagnosed with Alzheimer’s or dementia, but also people with no history of dementia.
They then asked people to answer questions about the day before the dementia diagnosis, including:How long had the person been in the office?
The researchers found that those who had had the most severe symptoms of dementia were more likely than those who were not to remember anything important from the day prior.
In the case of Alzheimer’s, memory loss was associated with the least frequent symptoms of the disease.
The researchers say it is important to remember that this is a study about memory, not dementia, so this could have implications for people with other mental health issues, as well.
“The study did not consider the relationship between dementia severity and changes in cognition,” lead researcher Dr Sarah McLean, of the Oxford University Clinical and Translational Science Unit, said.
“However, it is likely that people with a history of cognitive impairment, or those with other cognitive disorders, who have cognitive problems but who are unable to recall important information, may have less cognitive impairment.”
What is dementia?
Dementia is a chronic condition that causes problems with memory and reasoning, such as memory loss, as it occurs in older adults.
It is thought to affect around 2 per cent of the population worldwide.
It affects between one-quarter and two-thirds of older people, according the National Health Service.
In Alzheimer’s cases, it can be diagnosed when symptoms become so severe they cause a person to stop talking or stop seeing the world.
Symptoms can include memory loss and difficulty making decisions.
