Dangerous blood pressure caused by specific signalling in the brain

blood pressure, or hypertension, is suggested to be one of the leading risk factors for heart disease, according to Science Daily.

The process in which high blood pressure causes heart disease is not completely understood.

But now scientists at the Baker Heart and Diabetes Institute have found that high blood pressure caused by specific signalling from the brain promotes heart disease by altering stem cells with the bone marrow.

The results, demonstrate how an overactive sympathetic nervous system that causes elevated blood pressure can instruct bone marrow stem cells to produce more white blood cells that clog up blood vessels.

The Baker Institute's Head of Haematopoiesis and Leukocyte Biology, Associate Professor Andrew Murphy says the findings represent a new era of heart disease research.

Vegan diet ‘can boost mood and ease symptoms for those with Type 2 diabetics’, scientists say

Going vegan could help people with Type 2 diabetes feel happier and lose weight, say researchers.

Eating a plant-based or vegan diet helps to manage the condition, cuts blood sugar and can reduce depression, according to Daily Mail.

Scientists who reviewed 11 studies on more than 400 people with the condition found following a vegan or plant-based diet improved wellbeing and quality of life, and cut depression, which is believed to be three times as common in diabetics.

Say cheese! Eating fermented dairy products reduces your risk of a heart disease

Cheese lovers rejoice - eating cheddar, stilton and brie could reduce your risk of heart disease, according to Daily Mail.

Experts found eating fermented dairy products can lower the risk of the world's leading killer - but only in men .

Researchers tracked hundreds of participants over a 25-year period to make the conclusion.

This contradicts claims cheese can block a person's arteries and increase the risk of a heart attack because they are high in saturated fat.

Their data, suggests fermented dairy products have positive effects on cholesterol.

Exercise may lessen fall risk for older adults with Alzheimer's

Alzheimer's disease (AD) is a brain disease that causes changes that kill brain cells. AD is a type of dementia, which causes memory loss and problems with thinking and making decisions. People with AD and other forms of dementia have difficulties performing the daily activities others might consider routine, according to Science Daily.

Dementia takes a toll on those who live with it -- and it also places a burden on caregivers. Along with problems connected to memory, language, and decision-making, dementia can cause neuropsychiatric symptoms, such as depression, anxiety, changes in mood,

Stress in middle age can make your brain shrink and make your memory worse

Stress in middle age can make your brain shrink and make your memory worse, scientists have discovered, according to Daily Mail.

The brain-reducing effects of stress, identified in people in their 40s free from dementia, were found to be triggered by cortisol.

The high levels of the stress hormone may be an early warning sign someone may end up with dementia, the research suggests.

Stress also made people's thinking skills worse, the Harvard Medical School study, found.
