A new study in the United Kingdom is offering hope for dementia sufferers around the world.

The research was conducted by Cambridge University using 30,000 mental health patients, and it suggests that a drug commonly prescribed to those with mood disorders, such as bipolar disorder, may have unexpected benefits for those suffering from dementia.

Dementia is an umbrella term, and it refers to a range of progressive neurological disorders of which Alzheimer’s disease is the most prevalent. These disorders affect memory, thinking, and behavior, and it’s estimated there are about 5.8 million in the U.S. with Alzheimer’s and related forms of dementia. The pressing need to mitigate or cure this cruel disease has drawn greater attention recently, with urgent questions about President Biden’s mental state attracting renewed focus to the widespread epidemic. The possibility, however remote, of a cure for dementia is welcome news to many Americans.
