Dementia can be spotted 2 DECADES before it starts: Dizzy spells in middle age increase the risk of the condition by 40%, study finds

Dizzy spells in middle age may be a warning sign of dementia 20 years before symptoms appear, research suggests.

Scientists believe sudden drops in blood pressure - often evidenced by dizziness when rising - could cause lasting damage to the brain that increases the risk of dementia. A study of 11,000 middle-aged people found that those who suffer from this problem, known as hypotension, orthostatic, 40 per cent more likely to develop dementia later in lifeStudy leader Dr. Andreea Rawlings, of the Johns Hopkins Bloomberg School of public health in the United States, said: 'despite the fact that these episodes are fleeting, can have impacts that are long duration.' found that people who suffer from orthostatic hypotension in the middle ages were 40 per cent more likely to develop dementia than those who do not. 'it is a significant finding and we need to understand better what is happening.' team, who presented their findings at meeting of the scientific sessions of the life of the American Association of heart in Oregon, analyzed 11.503 people 45 to 64 for sudden bouts of low blood pressure. After lying down for 20 minutes, each participant is asked to do and had taken his blood pressure. Blood pressure is expressed in two numbers, systolic--top number - and diastolic - the lower one. The team's diagnosis of orthostatic hypotension as a fall of at least 20 points in systolic blood pressure and diastolic blood pressure at least 10. Approximately 6 per cent of the participants were defined with the condition.
Then during the next 20 years and found that 40 per cent more likely to develop dementia than those who had not experienced the same decline in blood pressure. It is a significant finding and we need to understand better what is happening. Dr. Andreea Rawlings, of the Johns Hopkins Bloomberg School of public HealthThey also shows a 15% higher rate of cognitive impairment on tests. The researchers said that it was not possible to say with certainty if the fall of blood pressure was directly related to dementia or an indicator of some other underlying disease. But they said that even a temporary reduction in blood flow to the brain could have a lasting effect. Dr. Rawlings said: ' identification of risk factors for cognitive impairment and dementia is important to understand the progression of the disease, and be able to identify the most at-risk gives us possible strategies for prevention and intervention. 'It is one of the factors that deserves further investigation.' Dr Laura Phipps, of the disease of Alzheimer Research UK, said: ' while many studies have focused on the risks of high blood pressure, these results suggest that transient low blood pressure also could have a long-term impact on the brain. ' this research adds to a growing and complex picture of how blood pressure changes throughout life can affect the brain.' Dr James Pickett, Director of research at the Alzheimer Society, added: 'many people experience this form of arterial hypotension that can reduce blood flow to the brain during a period short and result in a feeling of vertigo or dizziness.' it is not necessarily a cause for concern, but people often experiencing these symptoms should seek advice from your GP. More research is needed to investigate whether treat this type of hypotension would reduce risk of dementia.'Dr Mike Knapton, associate medical director of the British Heart Foundation, said: "is impossible to tell whether the condition is causing directly the development of dementia - however, this study will be useful for the design of further research to better understand this link." people who receive treatment for high blood pressure should continue to take your medication for blood pressure and not You should postpone this study since this will reduce your risk of having a heart attack potentially deadly or stroke. 'anyone can reduce their risk of developing dementia, including people with orthostatic hypotension, when you stop smoking, eat a healthy diet and being physically active.'

TOO MUCH SLEEP CAN BE DEMENTIA
Sleep more than nine hours a night could be a sign of early warning of Alzheimer's disease. Scientists last month found people who constantly spend this time in bed are two times more likely to develop dementia over the next decade. A change in sleep patterns is a red banner for Alzheimer's since it shows the brain, which controls wakefulness, has suffered damage. The Boston University Medical Center researchers also found those who slept nine hours or more also had smaller brain volumes, took longer p
