How Alzheimer's Disease Is Diagnosed




How Alzheimer's Disease Is Diagnosed

Alzheimer's disease is a condition in which the brain undergoes shrinkage in key areas, affecting memory, thinking and behavior. The symptoms progress so slowly that the changes are difficult to pinpoint over time, and it usually takes an outsider or a person that is not around the individual to suggest a doctor visit. It is classified as the most common form of dementia, which can interfere with daily life as it causes severe loss of intellectual capability and memory.
By taking the time to discover if an individual's inconvenient symptoms are truly caused by Alzheimer's, several things can be accomplished. Most importantly, the fear of the unknown will be destroyed. This fear causes anxiety in some patients and anger in others. If the time is taken to discuss the symptoms with a doctor, one of two things will be accomplished: the doctor will tell the patient that the symptoms are due to other causes or he will confirm that it is indeed Alzheimer's disease.

Infection of the Central Nervous System - Brain Abscess (Suppurative Encephalitis)




Infection of the Central Nervous System - Brain Abscess (Suppurative Encephalitis)

Diagnosis: In any patient having one of the underlying causes, features suggestive of meningitis, raised intracranial tension or focal neurological deficit should suggest the possibility or brain abscess. Lumbar puncture should not be routinely done in such cases since the risk or coning is high. Moreover the CSF may not show diagnostic changes in the case of localized abscess.
The diagnosis can be confirmed by CT Scan which should be done of an early stage. X-ray skull may give evidence of sinusitis and rarely gas in the abscess cavity, if the abscess is caused by gas-producing organisms or the abscess is communicating with the paranasal sinuses.
Course and prognosis: If left untreated, brain abscess is fatal. Complications include rupture into cerebral ventricles producing ventriculitis, meningitis, rise in intracranial tension and secondary epilepsy. If the abscess is diagnosed early and treated, full recovery may occur. Mortality is higher in brain abscess complicating congenital heart disease. The overall mortality in large series is 11-15%.

Blood Cancer - Causes and Treatment




Blood Cancer - Causes and Treatment

Blood is a part of the body. Blood has different components sch as red blood cells, white blood cells, platelets and plasma. The red blood cells (RBC), platelets also called monocytes because it is belong to the "myeloid" group and other white blood cells belong to the "lymphoid" group. Lymphoid cells are affected. Disease progresses quickly. This is most common among children. Blood cancer or Leukemia is actually a group of diseases, each of which impede with the normal functioning of blood cells and progressively weaken the system. Leukemia is classified as either Acute or Chronic. Blood and urine samples may also be tested for various substances, called tumor markers, which may indicate cancer.
Causes
A weakened immune system - this may be a result of drugs that suppress the immune system (such as those used for organ transplants), high doses of radiation (such as in radiotherapy for another cancer), or diseases that affect the immune system (such as HIV).
Treatment
In radio immunotherapy, an immunotoxin--a hybrid molecule formed by coupling an antibody molecule to a toxin--is injected into the patient.

What is a Bleeding Disorder and How it Can Be Treated?







What is a Bleeding Disorder and How it Can Be Treated?
Bleeding disorders refer to the situation, when the clotting system of human body becomes incapable of restraining blood from various body parts. For instance, the main body parts suffering from these disorders are nose and gums. Apart from this, menstrual bleeding in excessive amount is also a sign of bleeding disorder. Another type of bleeding disorder occurs, when cut and wound sites are not plugged by clotting process to disallow the flow of blood.
Causes of Bleeding Disorders
There can be two main causes of bleeding disorder:
1-You might inherit it from your ancestors, known as genetic cause.
2-Non-genetic causes can develop antibodies in your blood, which weaken the clotting system of blood and lead to bleeding disorders. Some of these causes include damage to red blood cells and blood vessels, liver disease or kidney failure, eclampsia after pregnancy, low platelets, vitamin K deficiency and excessive use of drugs like aspirin.
Three common bleeding disorders are hemophilia A, hemophilia B and von Willebrand Disease. While first two disorders are common with men, the last one can affect both genders.

Reasons of Blood Clotting and Nose Bleeding




Reasons of Blood Clotting and Nose Bleeding
Blood clotting is the body's way of stopping blood loss. When one gets a cut on the body with a knife or any other sharp object, blood vessels break and blood flows out. These blood vessels could either be an artery or a vein. If an artery has been cut, blood flows out stronger and faster as the pressure comes directly from the heart but if it's a vein then blood spills out slower. The human nose is one of the few parts of our body that has many nerves and blood vessels. It is exposed to dirt and pollutants that's why it produces mucus to filter these pollutants before they reach the airways and the lungs.
A minor cut is forms something like a knot around it. The blood gets exposed to the air so it gets thick and dries up. This has a double purpose, the knot traps blood cells from leaking out and at the same time it also prevents other particles from blending into the bloodstream. Nose bleeding that lasts for minutes can be caused by something more than booger scooping. The reason it bleeds is because blood vessels inside have ruptured through broken skin. Dryness inside may cause the skin to break.
