Many health apps designed to assist dementia patients and their caregivers have inadequate security policies or lack security policies altogether, new research concludes.

Alzheimer's disease (AD) represents the leading cause of dementia worldwide. Currently, challenges in making an early and definitive diagnosis of AD limit opportunities to intervene with disease-modifying therapies before substantial neurodegeneration occurs. Neurodegeneration in AD has been attributed to the accumulation of amyloid-? proteins (A?) in the central nervous system, and A? may be present up to 20 years prior to the onset of cognitive symptoms. Recently, noninvasive imaging techniques have been developed that can accurately detect and monitor A? deposition in the retinas of rodent AD models. The use of similar techniques to assess A? accumulation in human retinas may enable significant advances in early detection and treatment of AD.

A new simulation of the dementia epidemic estimates the economic impact the disease has on households and public insurance programs and provides a tool for projecting the impact that different interventions could have.

Scientists have identified a basic biological mechanism that kills neurons in amyotrophic lateral sclerosis (ALS) and in a related genetic disorder, frontotemporal dementia (FTD), found in some ALS patients. ALS is popularly known as Lou Gehrig’s disease. The researchers were led by J. Paul Taylor, M.D., Ph.D., chair of the St. Jude Cell and Molecular Biology Department and a Howard Hughes Medical Institute investigator; and Rosa Rademakers, Ph.D., of the Mayo Clinic in Jacksonville, Florida. The findings appear today in the journal Neuron.

When a US war veteran with dementia was convinced he needed to return to Vietnam, a Lt Col stepped in.
