It is highly likely that the Alzheimer’s results from a complex and interrelated combination of genetic and non-genetic factors. These so called risk factors influence a person’s risk to developing Alzheimer’s disease. Currently, each of these risk factors is the subject of a great deal of research around the world. Although cardiovascular risk factors, such as hypercholesterolaemia, hypertension, diabetes, and smoking, are associated with a higher risk of onset and course of Alzheimer’s, statins, which are cholesterol lowering drugs, have not been effective in preventing or improving the course of the disease.
Too much alcohol, particularly if associated with a diet deficient in thiamine (Vitamin B1) can lead to irreversible brain damage. This dementia is preventable. If people don’t drink, or they drink at a safe level, then they cannot develop Alcohol Related Dementia. The most vulnerable parts of the brain are those used for memory, and for planning, organizing and judgment, social skills and balance. If the individual stops drinking there may be some improvement.
A significant number of people diagnosed with dementia are found to have tiny spherical structures called Lewy bodies in the nerve cells of their brains. It is thought these may contribute to the death of brain cells. The symptoms of this form of dementia are often mild at the outset and can be extremely variable from day to day. Common symptoms include: Fluctuation in the condition Visual hallucinations
There are many different forms of dementia and each has its own causes. Alzheimer’s Disease is the most common form of dementia, accounting for between 50% and 70% of all dementias. The effects of the different types of dementia are similar, but not identical, as each one tends to affect different parts of the brain. Dementia, also referred to as senility, is a broad category of brain diseases that cause a long term and often gradual decrease in the ability to think and remember that is great enough to affect a person’s daily functioning.
Asthma is a chronic lung condition that is characterized by difficulty in breathing. People with asthma have extra sensitive or hyper-responsive airways. During an asthma attack, the airways become irritated and react by narrowing and constructing, causing increased resistance to airflow, and obstructing the flow of the air passages to and from the lungs. A few people seem to get asthma attacks only when they run or take other exercise.
During an asthma attack, the airways become irritated and react by narrowing and constructing, causing increased resistance to airflow, and obstructing the flow of the air passages to and from the lungs. But what causes asthma? Why do some people develop asthma? Why is asthma more common in the western world? Asthma is not contagious. You cannot catch asthma from another person. However, you can inherit the asthma tendency from your parents, although people with asthma should not worry about their future children on this score.
The symptoms of Asthma include: Coughing. Coughing in people with asthma is often worse at night or early in the morning, making it hard for them to sleep. Wheezing. Wheezing is a whistling or squeaky sound when you breathe. A tight feeling in the chest. This can feel like someone is squeezing or sitting on your chest. Shortness of breath. Asthma sufferers often say they can’t catch their breath, or they feel breathless or out of breath.
Asthma (pronounced AZ-muh) is defined in Essential Allergy, by Niels Mygind, Ronald Dahl, Soren Pedersen and Kristian Thestrup-Pedersen 2nd edition as : A lung disease characterised by: 1, variable and reversible airway obstruction; 2, airway inflammation; and 3, bronchial hyper-responsiveness. Asthma is a chronic inflammatory disease that makes airways (bronchial tubes) particularly sensitive to irritants, and this is characterized by difficulty in breathing. Asthma is a highly ranked chronic health condition in adults in most western countries, and it is the leading chronic illness of children.
