What Is Embolism? What Are The Different Types Of Embolism?
An embolism - from the Greek çİmbolos meaning "stopper" or "plug" - is the term that describes a condition where an object called an embolus is created in one part of the body, circulates throughout the body, and then blocks blood flowing through a vessel in another part of the body. Emboli (plural of embolus) are not to be confused with thrombi (plural of thrombus), which are clots that are formed and remain in one area of the body without being carried throughout the bloodstream.

Alzheimer's Society Comment On Research Into Impact Of Vitamin D On Brain Performance

A study of 3,133 men from a variety of test centres across Europe has shown that lower 25 (OH) D levels (vitamin D levels) were associated with poorer brain performance (in middle aged and older men). The study looked at a number of cognitive function tests with only one being linked to vitamin D statistically. The study did not look at cognitive function in women. Alzheimer"s Society comment: "One in three people over 65 will die with dementia making research into this area vital. This study, including over 3,000 men from a number of European locations, shows that maintaining vitamin D levels could play a role in reducing the decline of brain function. However, further research is needed to determine whether or not vitamin D can help preserve brain function in older people or reduce risk of dementia. As vitamin D is readily available to most people, through exposure to sunshine or eating oily fish, it will be interesting to see the results of future studies. In the meantime, current evidence tells us that a healthy lifestyle, including a balanced diet and exercise, is the best way of reducing your risk of dementia."
