Population aging raises dementia rates. But particulate air pollution does too, and possibly more than expected. New research compares the two effects for the first time in a systematic way.
Sleep is not a passive state. While we sleep, the brain produces rhythmic electrical patterns that directly influence how memories are stored.
Most people with dementia do not have one disease. They have two or three simultaneously. That makes treatment research far more complicated than assumed for decades.
Drinking two to three cups of coffee a day is associated with a 35 percent lower risk of dementia.
In ALS and a form of frontotemporal dementia, a protein called TDP-43 clumps together in nerve cells — and kills them.
The immune system doesn’t stay neatly separate from the brain. As it ages and becomes chronically inflamed, it appears to actively promote dementia and other neurological diseases — a connection that may…
A quick afternoon nap sounds harmless — even healthy. But a new study suggests that older adults who nap frequently and for long stretches face a significantly higher risk of dying sooner…
Surviving malaria is not the same as escaping it unharmed. New research shows the infection can leave measurable cognitive damage that persists long after the parasite is gone.
Older adults who received a high-dose flu vaccine showed a greater reduction in dementia risk than those who got the standard shot.
A quarter of older patients become confused after surgery. It sounds temporary. But the brain damage often isn’t. Now researchers have identified a potential mechanism — and a place to intervene.
Around a quarter of older people become acutely confused after surgery. Most recover, but the episode leaves a mark: it permanently accelerates cognitive decline.
LDL cholesterol has long been flagged as a cardiovascular risk factor. Now evidence is building that oxidized LDL particles play a specific role in vascular dementia — through a mechanism that starts…
