So, what exactly is this Cerebrovascular disease or Cerebral Vascular Disease and how does it occur? What is a stroke and how is it related to a cerebrovascular disease?
According to the Medical Dictionary a Cerebrovascular Disease is defined as "disease of the blood vessels and, especially, the arteries that supply the brain. Cerebrovascular disease is usually caused by atherosclerosis and can lead to a stroke."
To explain this in simple terms, a Cerebrovascular disease can be caused due to any disease that affects the arteries supplying blood and oxygen to the brain. The most common disease being atherosclerosis which is caused due to fatty deposits (plaques) in the arterial wall which in turn causes narrowing of the arteries.
What is a stroke?
According to medical definitions: "A stroke, or cerebrovascular accident (CVA), occurs when blood supply to part of the brain is disrupted, causing brain cells to die. When blood flow to the brain is impaired, oxygen and glucose cannot be delivered to the brain. Blood flow can be compromised by a variety of mechanisms."
A stroke occurs when there is either a blockage of an artery or arteries that supply blood and oxygen to the brain, or a rupture of the artery or arteries due to any reason. Let us examine the reasons that could cause either of the two conditions.
The main reason for the blockage of arteries is given in the above paragraph, namely atheroscerosis.
Another factor that could cause a blockage in the artery or arteries is a blood clot, also known as Thrombosis. In this situation, the blood clots usually occur in the heart and parts of that blood clot then break off and travel (embolize) to the arteries in the brain and cause a stroke. This condition is known as Embolism which can cause Transient ischaemic attacks (TIAs) in the brain leading to a loss of brain function in one area.
The rupture of an artery causes hemorrhage (bleeding) in the brain and is known as Cerebral hemorrhage.
The most common condition that can cause bleeding within the brain is an uncontrolled High Blood Pressure.
A second condition that could affect the arteries is a defect or weakness in a blood vessel causing it to expand or balloon out is known as an aneurysm or arteriovenous malformations (AVM) in which there is an abnormal collection of blood vessels that are fragile and can cause bleeding.
A stroke can occur suddenly at any time causing the person to become unconscious and is a medical emergency that needs prompt attention. A person who suffers from a stroke will have loss of oxygen, blood or even bleeding in the brain which can cause severe brain damage within a few minutes (3-4) and therefore it is very important that the person should be taken to the hospital ASAP.
The month of August brings with it all the festivities that will continue on till the end of the year bringing on the New Year. 5th August 2009 will be celebrated as Rakshabandhan or Rakhi, a Hindu Festival sanctifying the relationship between brothers and sisters, wherein the sister ties a thread (Rakhi) on the brother's wrist. The Brother then Gifts his sister, something as a token appreciation and a vow to protect her for life.

The Muslims will begin their Ramadan on the 22nd of this month and finally the month culminates with the much awaited Lord Ganesha Chaturthi on the 23rd.
All these occasions demand a good collection of devotional songs that will be utilized from now onwards till the end of the year with the Durga Puja or Diwali celebrations and Christmas too for the Christians.

The recent sudden death of the King of Pop, Michael Jackson has been attributed to a cardiac arrest. However, the cause of the cardiac arrest has not been ascertained as yet. His death continues to be shrouded in mystery. It is only after the autopsy report is out that more light may be shed on the matter. His death has aroused a general curiosity among the populace as to the difference between a cardiac arrest and a heart attack, confusing one with the other.
Both the terms have been interchanged by people and media often causing them to get mixed up. However, a cardiac arrest is NOT the same as a heart attack. So, what is the difference between the two terms?
To put it simply, the heart muscles get weak and damaged when there is "inadequate supply of oxygen" to it from its arteries. This occurs due to a blockage in the blood vessel causing the flow of blood to be decreased and therefore weakening the heart muscle. The weakened heart muscles cannot pump sufficient blood out and may stop pumping altogether. This condition occurs slowly over a period of time and the person may experience occasional chest pains until finally it collapses one day leading to a heart attack. A heart attack is always characterized by severe chest pain. In medical terms it is also referred to as a Myocardial Infarction.
Read about Heart Attack Warning Signs. A heart attack needs prompt first aid treatment in the form of a CPR (Cardio Pulmonary Resuscitation) and taken to the hospital as soon as possible to revive the heart.
Also known as "Sudden Cardiac Arrest". The heart is an "electrical" Pump, which means that it requires electrical impulses to its "valves" to be able to regulate the flow of blood from one chamber to another and out. When this electrical circuit is disrupted or there is a sudden "short circuit" then the heart stops suddenly causing an "arrest". This condition causes a sudden drop in the blood pressure and blood is no longer forced into the muscles and organs of the body. This condition is known as "ventricular fibrillation" and is the most common reason for sudden death in patients. What is important in identifying this condition accurately is the fact that the brain is deprived of oxygen when there is a cardiac arrest or ventricular fibrillation, and if this oxygen deprivation lasts more than 3-4 minutes, it could cause death or even a state of coma. Prompt treatment WITHIN 3-6 Minutes in the form of "External or Internal Defirillation" or giving an electrical shock to the heart muscles is called for. If there is no defibrillator close by then CPR can be started and continued till the Ambulance arrives.
Read details about the causes, warning signs, risk factors and treatment of this condition here.
It is important to note that a heart attack can cause cardiac arrest. Therefore it is very important to GET HELP(call the ambulance) immediately, specially if a person collapses and stops breathing suddenly in front of you without any warning or signs of chest pain. Treat such cases as a cardiac arrest and begin to administer CPR.
Note: One should also differentiate between the terms Angina and Heart Attack. Angina is a symptom of "Coronary Heart Disease" or CHD also characterized by blocking of the coronary artery causing atherosclerosis.
"Angina pectoris (or simply angina) is recurring chest pain or discomfort that happens when some part of the heart does not receive enough blood and oxygen."
