A recently recognized form of dementia is changing the understanding of cognitive decline, improving the ability to diagnose patients and underscoring the need for a wider array of treatments.
Patients are increasingly being diagnosed with the condition, known as LATE, and guidelines advising doctors how to identify it were published this year. LATE is now estimated to affect about a third of people 85 and older and 10 percent of those 65 and older, according to those guidelines. Some patients who have been told they have Alzheimer’s may actually have LATE, dementia experts say.
