Dementia is a neurodegenerative disorder characterized by a decline in cognitive functioning, affecting a person’s memory, thinking, and behavior. It is one of the leading causes of disability and dependency among older adults worldwide.
According to the World Health Organization (WHO), globally, about 50 million people have dementia, and there are nearly 10 million new cases every year. With an aging population, the prevalence of dementia is expected to increase significantly in the coming years.
What Causes Dementia?
There are several causes of dementia. The most common cause is Alzheimer’s disease, which accounts for 60-80% of all cases.
Other causes include vascular dementia, which occurs due to a lack of blood supply to the brain, Lewy body dementia, frontotemporal dementia, and mixed dementia.
Scientists are still working to understand the underlying causes of dementia.
However, research indicates that several factors can increase a person’s risk of developing the condition, such as age, genetics, lifestyle factors, and socio-economic status.
The Link Between Finances and Dementia
A recent study published in the journal JAMA Psychiatry sheds light on the link between financial hardship and the risk of developing dementia. The study analyzed data from nearly 6,000 older adults in England who were over 50 years old.
The participants’ financial situation was assessed using a questionnaire, which asked about their income, savings, and assets. The researchers followed up with the participants after two, four, and seven years to assess their cognitive functioning and screen for dementia.
The results of the study showed that those who experienced financial hardship were more likely to develop dementia than those who did not.
Specifically, people who reported high levels of financial strain were 60% more likely to develop dementia than those who did not report financial strain.
Interestingly, the study found no significant association between income and the risk of developing dementia.
However, people who reported low levels of wealth and savings were more likely to develop dementia than those with higher levels of wealth and savings. The researchers suggest that financial hardship may increase the risk of dementia through stress and reduced access to health care and other resources that support cognitive health.
Other Factors That Affect Dementia
While financial hardship is a significant risk factor for dementia, other factors can also contribute to the condition. These include:.
Age
Age is the most significant risk factor for dementia. The risk of developing dementia increases with age, and most people with dementia are over 65.
Genetics
Research has identified several genes associated with an increased risk of developing dementia. However, the role of genetics in dementia is complex, and most cases of the condition are not entirely determined by genes.
Lifestyle Factors
Lifestyle factors such as diet, exercise, and smoking can also play a role in the risk of developing dementia.
A healthy lifestyle that includes regular physical activity, a balanced diet, and not smoking can help reduce the risk of developing dementia.
Educational Level
Research suggests that people with higher levels of education are less likely to develop dementia.
Educated people may have more cognitive reserve, which means they can compensate for the effects of brain damage, reducing the impact of dementia on their daily lives.
Medical Conditions
Certain medical conditions, such as hypertension, diabetes, and high cholesterol, can increase the risk of developing dementia. Managing these conditions through medication and lifestyle changes may help reduce the risk of dementia.
Conclusion
Dementia is a significant public health concern that affects millions of people worldwide. While many factors can contribute to the risk of developing dementia, financial hardship is a significant risk factor.
The study mentioned above highlights the importance of addressing financial strain as a means of reducing the risk of dementia. People experiencing financial hardship should seek support to manage their finances effectively and reduce stress to improve their cognitive health.
