The debilitating situation, which progressively robs individuals of their reminiscences, cognitive talents, language and independence, at present impacts greater than 55 million individuals internationally.
Dementia is brought on by a variety of ailments, the most typical of which is Alzheimer’s.
An enormous assessment of the accessible proof revealed in The Lancet journal on Wednesday stated that the “potential for prevention is excessive” within the combat in opposition to dementia.
The examine follows a earlier report in 2020 that additionally emphasised the significance of prevention.
On the time, the worldwide workforce of researchers estimated that 40 % of dementia instances had been linked to 12 threat components.

– EU turns down new drug –
Many years of analysis and billions of {dollars} have failed to provide a remedy or really efficient drug for dementia.
However for the reason that begin of final 12 months, two Alzheimer’s remedies have been accepted in america: Biogen’s lecanemab and Eli Lilly’s donanemab.
They work by focusing on the build-up of two proteins — tau and amyloid beta — thought of to be one of many primary methods the illness progresses.
Nevertheless, the advantages of the medication stay modest, they’ve extreme negative effects, and they’re usually very costly.
In distinction to the US, the European Union’s drugs watchdog final week refused to approve lecanemab, and it’s nonetheless contemplating donanemab.
Some researchers hope the truth that the brand new medication work in any respect means they’ll pave the best way for more practical remedies sooner or later.
Others want to concentrate on methods to stop dementia within the first place.
Masud Husain, a neurologist on the UK’s College of Oxford, stated that specializing in threat components “can be far more economical than creating high-tech remedies which to date have been disappointing of their impacts on individuals with established dementia”.
– ‘How way more may we do?’ –
The Lancet examine was welcomed by specialists within the area, amongst whom the significance of prevention is hardly debatable.
Nevertheless, some stated the concept almost half of all dementia instances could possibly be prevented must be put in perspective.
