In news that may be of interest to those seeking Alzheimer's care in Wales for a friend or family member, the BBC reports that scientists across the UK will be examining what effect genes have in age-related cognitive decline, with the aim of creating a greater understanding of the disease.
Although Alzheimer's is just one form of dementia, 36,500 people are thought to suffer with it in Wales alone and it can lead to memory loss, confusion and emotional depression.
Professor Julie Williams from Cardiff University said: "Finding genetic factors that contribute to late-onset Alzheimer's will form a basis for further research towards treatments."
Meanwhile, Rebecca Wood, chief executive of the Alzheimer's Research Trust, added: "Identification of these genetic factors will spur further vital research toward the treatments that we so desperately need."
Elsewhere, a study published in the medical journal of the American Academy of Neurology has revealed that a higher level of education or more mentally demanding job may preserve the memory more in Alzheimer's patients.
