Diabetes, dementia, and depression

A new study has connected snoring (and other forms of sleep apnea) to an earlier onset of mild cognitive impairment and memory problems. These can sometimes progress to Alzheimer's, but not always. Most significantly, the researcher notes that use of a CPAP machine prevents that early onset.

There is also another study that attributes depression, as well as diabetes, to the onset of dementia. Depression in particular, according to the study, raises the risk of dementia by 83%. Those familiar with depression's effects on the brain will be unsurprised to hear this; depression is often linked to other chronic health conditions, including diabetes and heart disease.
