According to the Swedish study, it found that chronic kidney disease may increase the risk of dementia. The people who are having chronic kidney disease, their kidneys gradually lose their ability to filter the blood from waste and eliminate fluids.
Risk Of Dementia Increases As The Functioning Of The Kidney Decreases
The study author Dr. Hong Xu a postdoctoral researcher at the Karolinska Institute in Stockholm said, there is much evidence on the relationship between the kidneys and brain, which clearly states that even if there is a little dysfunctioning in the kidneys, it will indeed affect the heart and cardiovascular risk also increases.
The study was done with the analysis of health data of 330,000 older people in Stockholm who don’t have dementia nor undergone any kidney transplants when the study commenced. After 5 years, a follow-up came that around 6% of participants were diagnosed with dementia.
As their kidney functioning decreased and eventually, the risk of dementia increased. According to the researchers, whose kidney filtration rate is below 30mL per minute, having dementia more than 4 times higher than the normal filtration rate that is 90L to 104L.
Other risk factors that cause dementia such as smoking, alcohol consumption, high blood pressure, and diabetes, and after adjusting all these, the researchers concluded that people with filtration rates of 30 to 59mL per minute had 71% more risk of dementia than a normal kidney and people with filtration level below 30mL had 162% higher risk.
An investigation is done for analysis of a blood test report of nearly 206,000 participants to estimate how fast their kidney function declined; because of the faster drop in the rates of kidney filtration, the risk of dementia increases.
Around 10% of the dementia cases in the study are associated with a kidney filtration rate of 60mL per minute, which is more than as compared to other factors such as diabetes and heart disease. If we look, our body is a network that functions other organs, and they rely on each other for proper functioning.
Since the brain and kidney are part of the cardiovascular system, that’s why they purely rely on each other. And due to this, if anyone has diabetes and hypertension, it disturbs the blood flow, and eventually, it damages the kidneys and the brain. Untreated hypertension and diabetes may lead to cognitive decline in the brain and the kidney; it leads to weakening the blood cells as they become harder to filter waste.
Xu said the risk of dementia with a chronic condition increases with age; as we get older, it’s obvious that the functioning of body organs also slows down, the functioning of the kidney gradually decreases as there is no such effective treatment for dementia, that is why it’s important to identify the factor which causes it.
They can prevent and slow down many dementia cases by treating kidney disease. Some suggested lifestyle adjustments that should be followed by the patients are: include omega-3 %, fatty acids in your diet, limit the sugar intake, Stay active, and do regular exercises. Physical activity can also improve cognitive abilities.
