Systemic inflammation drives brain neurodegeneration

n a richly valuable paper published recently in Frontiers in Cellular Neuroscience the authors describe the ways in which systemic inflammation causes neurodegeneration in the brain associated with cognitive decline and a host of neuropsychiatric disorders. In the short term this manifests the anorexia, malaise, depression, and decreased physical activity known as sickness behavior (SB) that occurs with inflammation due to infection. Permanent cognitive and behavioral changes due to neurodegeneration occur when inflammation is chronic. Discerning and targeting the causes of inflammation offers opportunities for treatment.

Blood pressure forced too low and cognitive impairment

Low daytime systolic blood pressure was independently associated with a greater progression of cognitive decline in older patients with dementia and MCI among those treated with AHDs. Excessive SBP lowering may be harmful for older patients with cognitive impairment.

Magnesium: insulin, brain, heart and inflammation

Magnesium may be the critical nutrient most commonly drained by modern environmental stress to suboptimal levels... Recent studies add evidence to its indication for insulin resistance, diabetes, cognitive impairment, atrial fibrillation, cardiovascular disease, and neurogenic inflammation.

Cognitive impairment associated with low but still 'normal' TSH

A study just published JCEM (The Journal of Clinical Endocrinology & Metabolism) offers evidence that TSH (thyroid stimulating hormone) levels when low but still 'normal' are associated with cognitive impairment and dementia.

Metabolic health status and aging determined by inflammation, not weight

Metabolic health is not reliably determined by weight or BMI (body mass index). Lean individuals can suffer from cardiovascular and other diseases involving metabolism, and evidence has been mounting that supports the notion of a subtype of obesity that is metabolically healthy. Inflammation can determine metabolic health in both obese and non-obese populations.

Brain atrophy is promoted by both high and low blood pressure

Brain atrophy, with progressive cognitive impairment, can include among causal factors neuronal loss due to diminished oxygen perfusion. Earlier posts have documented the importance of not over-medicating hypertension. A study just published in JAMA Neurology provides evidence that brain atrophy is promoted by low diastolic blood pressure in addition to hypertension.
