If someone has poorer cardiovascular fitness at the age of 18 and/or has a lower IQ, then he could suffer from dementia before the age of 60, according to a new study. The latest research and study has highlighted the facts that these groups of people with the above conditions could be soft target to be the victim of dementia.
According to soucres, in several extensive studies, researchers at the Sahlgrenska Academy of Gothenburg University have previously analyzed Swedish men's conscription results and were able to show a correlation between cardiovascular fitness as a teenager and health problems in later life.
In their latest study, based on data from 1.1 million young Swedish men, the Gothenburg researcher team shows that those with poorer cardiovascular fitness and/or lower IQ in their teenage years more often suffer from early-onset dementia.
Sahlgrenska Academy researcher Jenny Nyberg, who headed the study, said, "Previous studies have shown the correlation between cardiovascular fitness and the risk of dementia in old age. Now, for the first time, we can show that the increased risk also applies to early-onset dementia and its precursors.”
Expressed in figures, the study shows that men who when conscripted had poorer cardiovascular fitness were 2.5 times more likely to develop early-onset dementia later in life. A lower IQ entailed a 4 times greater risk, and a combination of both poor cardiovascular fitness and low IQ entailed a 7 times greater risk of early-onset dementia.
The increased risk remained even when controlled for other risk factors, such as heredity, medical history, and social-economic circumstances.
According to Prof. Georg Kuhn, senior author of the study , "We already knew that physical and cognitive exercise reduces the risk of neurological disease. Physical exercise increases nerve cell complexity and function and even generation of new nerve cells in the adult brain, which strengthens our mental and physiological functions. In other words, good cardiovascular fitness makes the brain more resistant to damage and disease.”
