Learn about Alzheimer’s disease and dementia – as soon as possible: A new method should aid in the early detection of both clinical pictures.

Researchers report that both factors are linked to the killing of neurons in the brain, which leads to progressive cognitive impairment.

In a new study, which was published in the magazineAttention has now been paid not only to causative agents, but to a new method that is supposed to aid early detection: pupil movement in conjunction with cognitive tests.
