A cough is basically a reflex action so the airways can be cleared of phlegm, mucus and other irritants like dust and smoke. An inflammation of the upper respiratory tract due to a virus could also cause a cough.

Coughing can be symptomatic of many conditions including bronchitis, asthma, the common cold, flu, whooping cough or smoking. There are even some prescribed medicines that can cause coughing such as ACE-inhibitors which are used to treat heart failure.

Sometimes a cough can be a symptom of an underlying serious medical condition such as heart failure, lung cancer, tuberculosis, pneumonia or a pulmonary embolism (which is a clot on the lung). Coughs that have been caused by things like flu or the common cold normally disappear after a few days, but coughs that have been caused by an infection of the lung, such as bronchitis, could persist for several weeks, even after the infection has cleared up and this is due to the inflammation of the airways which usually take a while to clear up.

Cough Mechanism and Receptors

If someone has been suffering from a cough for more than a couple of weeks after having a viral infection, they should go to their doctor for medical advice.

Alzheimer’s disease is a physical condition that affects the brain and is the most common form of dementia worldwide. A German neurologist by the name of Alois Alzheimer first described the disease in the early 1900’s and was he who the condition was named after.

Alzheimer

When the disease is present in the brain, types of “tangles” develop in the brains structure which kills brain cells. Disease sufferers also have a shortage of a chemical in the brain which is responsible for the transmission of messages. As the disease progresses over time, more areas of the brain are damaged and any symptoms then become more severe.

Early stage symptoms include memory lapses and difficulty in finding the right words to speak or describe something. The progression of the disease brings confusion, forgetfulness, mood swings and frustration and withdrawal due to communication and confidence issues.

Up to the present time, no one has been able to pinpoint one particular factor that contributes to the onset of Alzheimer’s disease but it is widely agreed that it is probably a combination of factors including age, genetic makeup, diet, environmental factors and general health. Some people may even have the disease for years before any symptoms appear.

Unfortunately, presently there is no known cure for the condition, but certain drugs have been produced that can help alleviate some of the symptoms or slow down the diseases progression.

Blood pressure is described as the pressure the force of blood applies to the artery walls as it flows through them. It is the pumping action of the heart that causes the blood to be under pressure. Normal blood pressure is an essential function in the workings of the body. Blood pressure is denoted by two numbers, 120/80 being an example (which happens to be considered an average blood pressure reading, by the way), with the first number being the systolic blood pressure, or the pressure when the heart is contracted while pumping the blood, and the second number is the diastolic blood pressure reading which is when the heart is at rest while filling with blood.

Naturally low pressure (usually thought of as lower than 90/60) doesn’t indicate any problems health wise. It could be normal for some people and indeed beneficial as it can lower incidences of stoke and coronary heart disease. It only becomes a problem if it is accompanied by symptoms such as fainting. This is normally caused by an underlying problem which would indicate that the blood pressure is not being regulated properly.

What to do in the case of Low Blood Pressure

If someone has constantly low blood pressure, then this could be classed as normal, however, if they have postural hypotension (blood pressure drops when standing up from a sitting position) or postprandial hypotension (blood pressure drops after eating), could mean there are underlying health problems. These could be taking drugs that are used to treat high blood pressure, illnesses that cause blood loss, diabetes, Addison’s disease (an adrenal gland disease), and early stages of pregnancy.

Treatment of low blood pressure normally depends on the underlying cause of the problem.
