The neglect of these risk factors diminishes this reserve. [141] Sensory impairments of vision and hearing are modifiable risk factors for dementia. [142] These impairments may precede the cognitive symptoms of Alzheimer's disease for example, by many years. [143] Hearing loss may lead to social isolation which negatively affects cognition. [144]
The heritability of DLB is thought to be around 30% (that is, about 70% of disease severity is due to external factors or chance). [92] There is overlap in the genetic risk factors for DLB, Alzheimer's disease (AD), Parkinson's disease, and Parkinson's disease dementia. [87] [93] The APOE gene has three common variants.
The addition of vision loss and high cholesterol as risk factors comes as the number of people living with dementia around the world is expected to increase from 57 million in 2019 to 153 million ...
While the rising burden from dementia is driven largely by age and genetic factors, experts say that there are “broad opportunities” to reduce risk in the population with better management of ...
The prevention of dementia involves reducing the number of risk factors for the development of dementia, and is a global health priority needing a global response. [1] [2] Initiatives include the establishment of the International Research Network on Dementia Prevention (IRNDP) [3] which aims to link researchers in this field globally, and the establishment of the Global Dementia Observatory ...
Now, new research has found a new risk factor to consider: light pollution. The study, which was published in Frontiers in Neuroscience on September 5, is the first to connect Alzheimer’s ...
The studies that made the cut for this meta-analysis focused on the association between loneliness and all-cause dementia, as well as the risk for two specific types of dementia—Alzheimer’s ...
Regarding incidence, cohort longitudinal studies (studies where a disease-free population is followed over the years) provide rates between 10 and 15 per thousand person-years for all dementias and 5–8 for AD, [234] [235] which means that half of new dementia cases each year are Alzheimer's disease. Advancing age is a primary risk factor for ...
