Given that the first stage of a seizure is strongly altered perception of sensory information, it seems to follow that the sensory area is affected first. In fact, epilepsy is strongly associated with sensory (and motor discussed next) cortex, which lies just behind the central fissure on each side of the brain. Posttraumatic epilepsy, a common complication of severe head injuries, may be the result of scar tissue formation near the sensory cortex. The abnormal firing spreads from the sensory area to an area for motor control. The second stage of a seizure is ictus and is characterized by convulsions.
CORRECT The carotid artery (artery to the brain) is narrowed in clients with a brain attack (stroke). A bruit is an abnormal sound heard on auscultation resulting from interference with normal blood flow. B) Elevated blood pressure. CORRECT When a client has a brain attack (stroke), the blood pressure will often respond by going up. Increased BP is a sign of increased intracranial pressure.
If a blood clot in a narrowed artery blocks the flow of blood to the part of the heart muscle, a heart attack occurs. The section of heart muscle that does not receive the blood begins to die. This condition is called myocardial infarction, or M.I. As a result of M.I., heart action can be seriously impaired. A heart attack may be a sudden episode.
These diseases cause the brain cells degenerate and die more quickly than the normal ageing process. This leads to a decline in a person's mental and physical abilities. Vascular dementia is caused when the blood flow is restricted or stopped, the brain cells will begin to die, resulting in brain damage. The vessels narrow when fatty deposits build up on the blood vessel walls, restricting the flow of blood. This can be more common in people who have high blood pressure, type 1 diabetes and those who smoke.
Cushing’s syndrome A healthy life is disturbed by a wide range of conditions, we refer to as diseases. Either chronic, malignt, mortal, genetic or even treatable; a disease is any abnormality in a human’s anatomy or physiology, based on a lexical point of view. According to Mayoclinic.com Cushing’s Syndrome is a chronic disorder in which the adrenal cortex produces excessive amounts of the hormone cortisol. It may also be induced iatrogenically by treatment with exogenous corticosteroids for other medical conditions. Cortisol is secreted by the adrenal glands under regulation by the pituitary gland and hypothalamus.
DEFINITION/ETIOLOGY: The most common cause of heart failure is coronary artery disease (CAD), which is a narrowing of the small blood vessels that supply blood and oxygen to the heart. Hear failure can also occur when an infection weakens the heart muscles, this disorder is called cardiomyopathy. Other heart problems that may cause heart failure include: Congenital heart disease, Heart attack, heart valve disease, and some types of abnormal heart rhythms. Diseases such as emphysema, severe anemia, hyperthyroidism, or hypothyroidism may also cause or contribute to heart failure Systolic heart failure means that your heart muscle cannot pump, or eject the blood out of the heart very well. Diastolic heart failure means that your hearts pumping chamber does not fill up with blood.
(Detroit: Gale, 2010). These are some causes to epilepsy: * head trauma resulting from a car accident, gunshot wound, or other injury. * alcoholism * brain abscess or inflammation of membranes covering the brain or spinal cord * phenylketonuria (PKU, a disease that is present at birth, often is characterized by seizures, and can result in mental retardation) and other inherited disorders * infectious diseases like measles, mumps, and diphtheria * degenerative disease * lead poisoning, mercury poisoning, carbon monoxide poisoning, or ingestion of some other poisonous substance * genetic
Transient Ischemic Attack (TIA) - Topic Overview What is a transient ischemic attack (TIA)? Some people call a transient ischemic attack (TIA) a mini-stroke, because the symptoms are like those of a stroke but do not last long. A TIA happens when blood flow to part of the brain is blocked or reduced, often by a blood clot. After a short time, blood flows again and the symptoms go away. With a stroke, the blood flow stays blocked, and the brain has permanent damage.
A stroke is usually classified as being either ischemic or hemorrhagic depending on whether there is a blood clot or internal bleeding in the brain. In an ischemic stroke, the blood vessel becomes a clot, which in turn blocks the artery and blood flow to the brain. Ischemic strokes are usually caused by atherosclerosis (narrowing of blood vessels), constricting the blood flow to the brain. 80% of all strokes are ischemic, but those who have this type of stroke have a much better chance of survival than those who experience a hemorrhagic
Cardiac problems such as heart failure/coronary artery disease that reduces the blood flow. Amnesia can cause memory loss and can be the first symptoms of a serious illness particularly in older adults. Infections such as UTI, respiratory infection or sepsis. Underactive thyroid can lead to apathy, depression or dementia. Hypoglycemia can cause confusion and personality changes when there is not enough sugar in the
