Dementia is the umbrella term used to describe neurodegenerative disorders that cause severe damage that have no cure. yet no cure.
Risk factors typically include genetics and age, experts believe that eye condition should also be included to the list of risk factors.
The way we view dementia has changed over the last years, as in time past it was thought of as a normal process of aging since the mind is deteriorating with the effects of aging. But, the perception has changed and dementia is recognized as a condition which can be treated and even reversed. This is why studies were conducted to find the best way to treat dementia, but also how to stop it from happening. A part of this process is the identification of the risk factors.
Researchers in across the United States said that improved eyesight could help prevent dementia in accordance with study published in JAMA NERL.
Joshua Ehrlich notes in the paperthat “we have known for a long years that visual impairment is an indicator of dementia risk. “We also found out that a significant portion of the visual impairment can be prevented or not treated.
The findings of the study indicated that better eye health could have prevented a mere 2 percent of dementia cases across the United States in 2018, roughly 100 thousand cases.
Researchers “found it remarkable that visually impaired people are not considered in models that are key to the risk factors for dementia which are used to determine the health policy and resource allocation,”Ehrlich describes.
One of the goals in the research is “demonstrate how visual impairment is the same impact as many other, long-standing and modifiable dementia risk factors,”they added.
In demonstrating the effect of eye health on dementia more patients can be detected earlier.
The statistics show that one out of three people born today will suffer from dementia during their lifetime.
The most prevalent form of dementia is Alzheimer’s disease.
Current risk factors for dementia include:
– The cognitive reserve
– Origins of ethnicity
– Conditions of health and diseases
However the eye health issue isn’t one of the main risk factors that can cause dementia.
Recent research suggests that sleep may play a key part in determining a person’s likelihood to develop dementia.
Researchers at Cambridge University University of Cambridge said seven hours of rest, instead of 8 hours is the best amount to fight off the effects of dementia.
Their recommendations come from an analysis of the sleeping patterns of half one million Britons between 38-73.
The National Health Service (NHS) currently recommends between six and nine hours of rest.
The professor Barbara Sahakian, co-author of the study, stated “getting an adequate night’s rest is essential throughout our lives however, it is especially important when we get older. The search for ways of improving sleep quality for seniors can be vital in helping them maintain their well-being and mental wellbeing, and avoid decline in cognitive function particularly for those suffering from mental illness and dementia,”he added.
Researchers also stated that sleeping too much as well as a lack of sleep may negatively impact the body.
