MS researchers find well-being differs with age in multiple sclerosis
The oldest group reported the lowest levels of depressive symptoms and the highest levels of Physical QOL. 'These results were unexpected,' said Dr. Strober, 'given the functional limitations, disease progression, and neurological lesions seen in the aging MS population. Contrary to our hypothesis, the trend by age paralleled the general population. Younger individuals with MS are at greater risk for depression and poor QOL. If confirmed, targeted screening for depression by age may be warranted in this population.' (2018-09-19)

Discovery could explain failed clinical trials for Alzheimer's, and provide a solution
Researchers at King's College London have discovered a vicious feedback loop underlying brain degeneration in Alzheimer's disease which may explain why so many drug trials have failed.

Healthcare cuts 'strongly linked' to the resurgence of measles
Studies show that primary reason for the measles outbreak, affecting several European countries, is the decline in vaccination coverage, for which mainly the 'spread of anti-scientific theories' can be blamed. However, a new study in the European Journal of Public Health shows that cuts in public health expenditure also play an important role, with measles, mumps, rubella (MMR) vaccination coverage decreasing 0.5 percentage points for each 1 percent expenditure cut (2018-09-12)

Older adults fitted with cochlear implants exhibit poor brain function
Older adults fitted with a cochlear implant to compensate for severe hearing loss have significantly poorer cognitive function than their normal-hearing counterparts. Hearing loss is a risk factor for cognitive decline, so this new finding suggests cochlear implants cannot fully compensate for this deterioration in brain function. Rehabilitation treatment should be tailored to the cognitive profile of cochlear implant patients, with further research determining the impact of cochlear implants on cognition and its decline. (2018-09-12)
