Blood vessels provide your brain cells with sugars, oxygen and other nutrients required to function. The development of new blood vessels helps maintain a blood supply to all the tissues within your brain. All blood vessels contain a lining of...
Defects in brain vessels, notably arteries, include hardening by atherosclerotic plaque, which narrows carotid arteries and can cause stroke; formation of berry aneurysms, which can rupture causing subarachnoid hemorrhage; deposition of amyloid in...
A transient ischemic attack (TIA) is a stroke that lasts for less than 24 hours. The Mayo Clinic states that one-third of patients that have a TIA will have a stroke later on in life. Patients that develop a TIA typically have an associated...
Stroke occurs when a blood vessel leading to the brain is ruptured, or when a blood vessel of the brain becomes blocked by a clot, according to the Mayo Clinic. A ruptured blood vessel in the brain leads to a hemorrhagic stroke in which bleeding...
A stroke is a blockage of blood flow to the brain either because of a blocked blood vessel or a bleeding blood vessel. The brain is sensitive to a disruption of blood flow and brain cells can die, causing permanent damage. According to Medline...
Small vessel disease or a small vessel stroke is also called a lacunar infarction. The National Stroke Association notes that it occurs when the flow of blood in a small arterial vessel leading to or in the brain is blocked. Small vessel strokes...
The large and small blood vessels of the body are responsible for the circulation of blood, oxygen and nutrients to the brain and tissues of the body. Diseases of the small blood vessels in the brain results in a eduction in the flow of blood to...
A brain aneurysm is a sac-like formation in a weakened area of a blood vessel in the brain. Filled with blood, the sac often causes no major symptoms; however, it may leak or rupture if the walls of the vessel become too fragile. Treatment for...
Hemorrhagic stroke involves a hemorrhage within the brain. A blood vessel bursts, resulting in increased pressure in the brain due to too much blood pushing on the brain tissue. It's essentially the opposite of an ischemic stroke, in which the...
A stroke occurs when a blood clot or broken blood vessel interrupts the flow of blood to the brain. The difference between a mild stroke and a major one is timing. Getting emergency treatment within an hour of a stroke can prevent disability. The...
Strokes occur when a blood vessel in your brain ruptures or is blocked, which can cause your brain cells to die if they do not receive adequate amounts of blood and oxygen. Certain herbs may help prevent strokes, although it is always wise to...
A cerebral aneurysm is a condition that arises when there is a weak spot in a blood vessel in the brain. If blood becomes trapped in the weakened blood vessel, pressure can build up, causing the aneurysm to rupture. An estimated 6 percent of...
According to the American Stroke Association, stroke is the third leading cause of death in the United States. Two primary causes of stroke are ischemia and hemorrhage. Ischemia, the most common, causes reduced blood flow to the brain, depriving...
A stroke is an interruption of blood supply to a certain area of the brain. Diabetes is a condition in which blood sugar levels are uncontrolled, which can damage small blood vessels, often those in the brain. Thus, uncontrolled diabetes is a risk...
A brain aneurysm, also called a cerebral aneurysm, can occur anywhere on a blood vessel or artery in the brain. According to the National Institutes of Health, a brain aneurysm is "a weak or thin spot on a blood vessel in the brain that balloons...
A stroke occurs when the brain does not get the blood and oxygen it needs to function normally. Sometimes it is obvious a person is having a stroke based on the symptoms being experienced. At other times the symptoms may be subtle. In some cases...
A stroke is a debilitating attack that strikes the brain, but can affect the whole body. A stroke can be caused by a clot or a hemorrhage in a blood vessel in the brain, and when blood supply is cut off, serious damage is done to the brain. A...
A stroke occurs when a blood vessel to the brain either bursts or becomes clogged by a blood clot, interrupting oxygen to brain cells. This causes brain cell death, which in turn disables the parts of your body controlled by those cells. The...
A stroke can leave a patient debilitated, in chronic pain and dependent on others. The National Institute of Neurological Disorders and Stroke promotes exercise regimens because they can reverse the damage of a stroke and allow a patient to regain...
One way in which diabetes can affect the brain is if it causes a condition known as ketoacidosis. When the body runs out of insulin, it is forced to break down fats for energy. One of the byproducts of this metabolism is a compound called ketones....
A stroke is the reduction of blood flow to a certain part of the brain caused by a blocked blood vessel or a bleeding blood vessel in the brain. Because the brain heavily relies on oxygen and nutrients in blood to properly function, a reduction in...
Painful tingling throughout our body can leave you debilitated, in chronic pain and dependent on others. This tingling is a symptom of many conditions, and discovering the source is imperative for proper treatment. Consult with your health care...
A TIA, or transient ischemic attack, is similar to a stroke, but symptoms resolve in a few minutes to 24 hours. TIAs are often referred to as ministrokes, but may be warning signs of a future stroke. MayoClinic.com states that one in three people...
A stroke may be one of two types. A hemorrhagic stroke occurs when a blood vessel in the brain breaks, resulting in bleeding, which damages other brain cells. An ischemic stroke occurs when there is a blockage in a blood vessel of the brain,...
A brain aneurysm or cerebral aneurysm is a ballooning or an abnormal widening in a blood vessel in the brain. According to MedlinePlus, they usually occur when the wall of a blood vessel has a weak area. It may be present from birth or it can...
Sometimes referred to as a cerebrovascular accident (CVA), a stroke occurs in the event of oxygen deprivation to brain cells. According to the American Heart Association (AHA), the lack of oxygen to nerve cells within the affected area of the...
The brain is the creator and regulator of personality, thought, conscious and unconscious action, and emotion. The brain is composed of nerves, which are specialized cells that "talk" to each other through electrical impulses. When these...
Hypoglycemia, which is a complication of diabetes, is the medical term for dangerously low blood glucose. A stroke occurs when the blood supply to the brain is interrupted by a blocked or burst vessel in the brain. Strokes kill brain cells and...
Heart conditions affect children, adolescents, young adults and seniors. Congenital heart defects may show up at birth, or they may manifest later in life. Heart disease is any condition that affects the normal function of the heart's rhythm and...
A migraine headache is a neurologic headache that occurs in the brain due to a spasaming or instability of the blood vessels of the brain that then causes other symptoms. In this video learn more about migraines and how to treat them.
Fainting, also called syncope, is a loss of consciousness that occurs when there is a reduction of blood to the brain. In this video learn more about this condition and how to prevent it.
