Stroke is the third leading cause of death in America and is one of the leading causes of disability. Just like everything else in our body, our brain is fed by blood through arteries. And just as high blood pressure can damages the arteries of our heart, it can damages the arteries leading to our brain. If the arteries to our brain are only partially blocked, you can experience a transient ischemic attack- kind of like mini stroke. Its a brief, temporary disruption of blood to your brain caused…

Introduction Sepsis is a serious infection of the blood or tissues that affects the whole body. Septic shock is the final, most serious stage of this infection.

The drop keeps your organs from getting enough oxygen, causing them to fail. What increases the risk? You are more likely to develop this condition if: You are very young or elderly.

Merriam-Webster defines hypothermia as a condition in which the temperature of the body is very low. This condition is a medical emergency that occurs when the body loses more heat than what it is able to produce; hence, the body temperature decreases. The part of the brain called the hypothalamus is responsible for controlling body temperature; therefore, hypothermia is the result of the dysfunction of the hypothalamus. In order for a person to become hypothermic, their body temperature must be…

Hypovolemia is a state in which the blood volume, specifically the volume of the blood plasma, is decreased. This can also lead to an imbalance in the volume contraction, or a decrease in the volume of body fluid, which includes osmolytes. Hypervolemia is often linked with sodium depletion, and is distinctly different from dehydration. Causes include loss of blood, loss of plasma, and loss of osmolytes via diarrhea and vomiting. It is recognized by tachycardia and diminished blood pressure, as…

Moyamoya disease is a progressive, occlusive disease affecting the cerebral vasculature and the arteries that feed it. Moyamoya is a Japanese term meaning “puff of smoke.” When you view the appearance of the disease on an angiogram the abnormal vascular collateral networks developing adjacent to the stenotic vessels. This disease causes the carotid artery in the skull becomes blocked or narrowed. This will cause the blood flow to your brain to become greatly reduced. Tiny blood vessels…

It is more common in people with diabetes and autoimmune diseases and usually affects the hands and feet. At first the diseased part may be discolored and cold to the touch; later it becomes distinct from nearby healthy tissue, turning dark and dry. The tissue withers…

Atherosclerosis is a cardiovascular disease whereby the arteries harden as a result of fatty deposits also known as plaque.Ather\o prefix meaning yellowish, fatty plaque and -sclerosis suffix meaning hardening. (Tsutsumi, n.d.).One of the main contributing factors towards this disease is high levels of cholesterol. The fatty deposit, plaque, grows steadily including both fibrous connective tissues. As the plaque accumulates, the walls of the arteries thicken and stiffen, and the obstruction of…

roundworm known as Dirofilaria Immitis. A parasite is an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense. Over 70 species of mosquitos can serve as an intermediate host of which the most common carriers would be the Aedes, Anopheles and Culex. It is commonly diagnosed in dogs but can also affect cats as well as ferrets. Infections are also possible in wild animals such as wolves, coyotes, foxes, California gray seals, sea lions…
