It is well known that hypertension, raised blood pressure, results in greater risk of a range of age-related conditions, particularly cognitive decline and dementia. The mechanisms of interest include damage to the blood-brain barrier, allowing unwanted molecules and cells into the brain, where they can spur chronic inflammation, and rupture of small blood vessels in the brain, resulting in microbleeds that are effectively tiny strokes, destroying small regions of tissue. Over time, this all adds up, and is why even methods that force a lowering of blood pressure without addressing the underlying causes of hypertension can...

CONCLUSION: The treatment of modifiable risk factors can have a preventive effects on cognitive decline and dementia. More research is needed to identify subgroups with the greatest likelihood of benefits. PMID: 31440769 [PubMed - as supplied by publisher]

Authors: Wanleenuwat P, Iwanowski P, Kozubski W Abstract Alzheimer's disease (AD) is the most common form of dementia manifesting as alterations in cognitive abilities, behavior and deterioration in memory which is progressive, leading to gradual worsening of symptoms. Major pathological features of AD are accumulations of neuronal amyloid plaques and neurofibrillary tangles, with early lesions appearing primarily in the hippocampus, the area of the brain involved in memory and learning. Cardiovascular related risk factors are believed to play a crucial role in disease development and the acceleration of cognitive ...

Maintaining fitness through the practice of regular exercise improves health in old age, slowing the pace of damage to the brain and consequent cognitive decline. While there is largely only correlational data in humans to show a link between exercise and a slower pace of neurodegeneration, many animal studies make it clear that exercise causes an improved trajectory for health in later life. It does not extend overall life span in mice, as is the case for calorie restriction, but is otherwise very effective for an intervention that is essentially free. This beneficial outcome is likely due to a combination of overl...

CONCLUSIONS: Physicians had a lower prevalence for dementia than the general population. The prevalence for dementia in specific subgroups of physicians was higher, which needs to be clarified by further studies. PMID: 31428999 [PubMed - as supplied by publisher]
