Dementia is about 50 millions of people, worldwide, with the number of sufferers expected to double in the next 20 years. The condition is currently incurable, but experts estimate that for every five years its onset is delayed by 50% the number of deaths.
Now North Dakota State University researchers say reduced grip strength is an early sign of cognitive impairment, which can lead to dementia.
The scientists observed that for every five kilograms of reduction in grip strength was recorded 18% greater likelihood of severe cognitive impairment. It is worth noting that, a healthy man 30 years has a grip strength on average 40 kilos.
Η μελέτη που δημοσιεύθηκε στο τελευταίο τεύχος του Journal of Alzheimer’s Disease το 2019 concludes that physicians should evaluate grip strength in the examination of the patient for any cognitive impairment.
Σύμφωνα με τον καθηγητή Ryan McGrath, head of the study, "Measuring grip strength is easy, simple and non-invasive. At the doctor's office we can ask the patient to apply pressure by closing his palm on a hand dynamometer three times. But even at home one can calculate the grip power on one's own. How; With a wrist spring that you can easily buy or find in the gym ».
The normal process of aging naturally leads to weakening and strength of the grip of our hands, affecting daily simple and complex activities.
Like any muscle group, our hands need training so that they do not weaken.
