Combined occipito-parietal cortex pathology and striatal dopamine loss predicted conversion to dementia with Lewy bodies with a sub-distribution…Combined occipito-parietal cortex pathology and striatal dopamine loss predicted conversion to dementia with Lewy bodies with a sub-distribution hazard ratio of 38.68.
Video-derived balance score tracks age and fall risk
Tested in 180 participants, the StaBLE score correlated strongly with age (ρ = -0.76) and separated individuals at risk of falling from those who were…Tested in 180 participants, the StaBLE score correlated strongly with age (ρ = -0.76) and separated individuals at risk of falling from those who were not.
