Cambridge: A brand new analysis led by the College of Cambridge, have recognized a hyperlink suggesting that lithium may lower the danger of creating dementia. The analysis was revealed within the journal, ‘PLoS Medication.’ The analysis performed a retrospective evaluation of the well being information of practically 30,000 sufferers from Cambridgeshire and Peterborough NHS Basis Belief.
The sufferers had been all around the age of fifty and accessed NHS psychological well being companies between 2005 and 2019. The evaluation instructed that sufferers who acquired lithium had been much less prone to develop dementia than those that didn’t, though the general variety of sufferers who acquired lithium was small.

Dementia is the main reason behind dying in aged Western populations, however no preventative remedies are presently obtainable. Greater than 55 million individuals worldwide have dementia, with Alzheimer’s illness the commonest type.
“The variety of individuals with dementia continues to develop, which places enormous stress on healthcare methods,” stated Dr Shanquan Chen from Cambridge’s Division of Psychiatry, the paper’s first writer.
“It has been estimated that delaying the onset of dementia by simply 5 years may cut back its prevalence and financial affect by as a lot as 40 %,” he added.
Earlier research have proposed lithium as a possible therapy for individuals who have already been identified with dementia or early cognitive impairment, however it’s unclear whether or not it might delay and even stop the event of dementia altogether, as these research have been restricted in dimension.
Lithium is a temper stabiliser normally prescribed for circumstances similar to bipolar affective dysfunction and melancholy.
“Bipolar dysfunction and melancholy are thought-about to place individuals at elevated threat of dementia, so we had to ensure to account for this in our evaluation,” stated Chen.
Chen and his colleagues analysed knowledge from sufferers who accessed psychological well being companies from Cambridgeshire and Peterborough NHS Basis Belief between 2005 and 2019.
Sufferers had been throughout 50 years of age, acquired not less than a one-year follow-up appointment, and had not been beforehand identified with both delicate cognitive impairment or dementia.
Of the 29,618 sufferers within the examine cohort, 548 sufferers had been handled with lithium and 29,070 had not. Their imply age was slightly below 74 years, and roughly 40 % of sufferers had been male. For the group that had acquired lithium, 53, or 9.7 per cent had been identified with dementia.
For the group that had not acquired lithium, 3,244, or 11.2 per cent, had been identified with dementia.
After controlling for components similar to smoking, different drugs, and different bodily and psychological diseases, lithium use was related to a decrease threat of dementia, each for brief and long-term customers.
Nevertheless, because the general variety of sufferers receiving lithium was small and this was an observational examine, bigger scientific trials can be wanted to ascertain lithium as a possible therapy for dementia.
One other limitation of the examine was the variety of sufferers who had been identified with bipolar dysfunction, which is often related to an elevated threat of dementia.
“We anticipated to seek out that sufferers with bipolar dysfunction had been extra prone to develop dementia since that’s the commonest motive to be prescribed lithium, however our evaluation instructed the alternative,” stated Chen.
“It is too early to say for positive, however it`s attainable that lithium may cut back the danger of dementia in individuals with bipolar dysfunction,” he concluded.
