Scientists are investigating how the underlying condition processes in mixed dementia start and influence each other. Further knowledge benefit in this area will assist researchers much better understand these conditions and develop an ext personalized prevention and also treatment strategies.

Other problems that reason dementia-like symptoms have the right to be stopped or even reversed through treatment. Because that example, normal pressure hydrocephalus, an abnormal buildup that cerebrospinal fluid in the brain, often resolves through treatment.

By researching the brain of world who have actually died, researchers learn an ext about how types of dementia influence the brain and exactly how we might far better treat and prevent them.
