When admitted to a hospital emergency department, elderly patients who suffer from dementia and delirium often do not understand why they are there. They also tend to not understand ER discharge instructions.

A number of factors prevent Alzheimer's disease research from reaching its optimal potential, according to a new report.

In a placebo-controlled study, researchers in Sweden have shown that an operation can help patients who have dementia caused by white matter changes and hydrocephalus (a build-up of fluid inside the skull).

A study by the Institute of Aging Research suggests that treating the symptoms and stress associated with advanced dementia may be more efficient than aggressive treatment for the illness.

A key protein involved in Alzheimer's disease is produced at a normal rate but is not sufficiently removed in the disease.
