Encephalopathy is a term that means brain disease,
damage, or malfunction. Encephalopathy can present a very broad spectrum of
symptoms that range from mild, such as some memory loss or subtle personality
changes, to severe, such as dementia,
seizures, coma, or death. In general,
encephalopathy is manifested by an altered mental state that is sometimes
accompanied by physical manifestations (for example, poor coordination of limb
movements).
The term encephalopathy is very broad and in most cases,
is preceded by various terms that describe the reason, cause, or special
conditions of the patient that leads to brain malfunction. For example, anoxic
encephalopathy
means brain damage due to lack of oxygen, and hepatic encephalopathy means brain
malfunction due to liver disease. Additionally, some other terms either describe body conditions or
syndromes that lead to a specific set of brain malfunctions. Examples of these
are metabolic encephalopathy and Wernicke's encephalopathy (Wernicke's
syndrome). There are over 150 different terms that modify or precede
"encephalopathy" in the medical literature.
What causes encephalopathy?
The causes of encephalopathy are both numerous and varied.
Some examples of causes of encephalopathy include:
infections (bacteria,
viruses, parasites, or prions),
anoxia (lack of oxygen
to the brain),
alcohol consumption,
liver failure,
kidney failure,
metabolic
diseases,
brain tumors,
many types of toxic chemicals,
alterations in pressure
in the brain, and
poor nutrition.
These examples
do not cover all of the potential causes of encephalopathy but are listed to
demonstrate the wide range of causes.
Although numerous causes of encephalopathy are k...
Shigellosis is an infectious disease caused by a group of bacteria called
Shigella. Most who are infected with Shigella develop diarrhea, fever, and
stomach cramps starting a day or two after they are exposed to the bacteria. The
diarrhea is often bloody. Shigellosis usually resolves in 5 to 7 days. Persons
with shigellosis in the United States rarely require hospitalization. A severe
infection with high fever may be associated with seizures in children less than
2 years old. Some persons who are infected may have no symptoms at all, but may
still pass the Shigella bacteria to others.
What sort of germ is Shigella?
The Shigella germ is actually a family of bacteria that can cause diarrhea in
humans. They are microscopic living creatures that pass from person to person.
Shigella were discovered over 100 years ago by a Japanese scientist named Shiga,
for wh...

Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, medication. Some of the renal causes of kidney failure are from sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones. Treatment options included diet, medications, or dialysis.
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
High blood pressure, also known as hypertension, is a repeatedly
elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above
140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
A brain tumor can be either benign (non cancerous) or malignant (cancerous), primary, or secondary. Causes and risk factors include age, gender, family history, and exposure to chemicals. Symptoms range from headaches, leg and feet numbness to seizures. Treatment is dependant upon the type and location of the brain tumor.
Cirrhosis of the liver refers to a disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. This disease leads to abnormalities in the liver's ability to handle toxins and blood flow, causing internal bleeding, kidney failure, mental confusion, coma, body fluid accumulation, and frequent infections. Symptoms include yellowing of the skin, itching, and fatigue.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Liver disease can be cause by a variety of things including infection (hepatitis), diseases such as gallstones, high cholesterol or triglycerides, blood flow obstruction to the liver, and toxins (medications and chemicals). Symptoms of liver disease depends upon the cause; however, common symptoms may include nausea, vomiting, upper right abdominal pain, and jaundice. Treatment depends upon the cause of the liver disease.
Hepatitis C is an inflammation of the liver due to the hepatitis C virus (HCV), which is usually spread by
blood transfusion, hemodialysis, and needle sticks, especially with intravenous
drug abuse. Chronic hepatitis C may be treated with interferon, usually in combination with anti-virals.
Dementia is a significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. There are different criteria classification schemes for dementias such as cortical, subcortical, progressive, primary, and secondary dementias. Other conditions and medication reactions can also cause dementia. Dementia is diagnosed based on a certain set of criteria. Treatment for dementia is generally focused on the symptoms of the disease.
Hypoglycemia is a syndrome caused by low blood sugar. Symptoms of hypoglycemia include palpitations, trembling, intense hunger, sweating, nervousness, and weakness. Consuming lifesavers, table sugar, soda, and juice are good treatment options for hypoglycemia.
Alcoholism is a disease that includes alcohol craving and continued drinking despite repeated alcohol-related problems, such as losing a job or getting into trouble with the law.
The hepatitis B virus is a unique, coated DNA virus belonging to the Hepadnaviridae family of viruses. The course of the virus is determined primarily by the age at which the infection is acquired and the interaction between the virus and the body's immune system. Successful treatment is associated with a reduction in liver injury and fibrosis (scarring), a decreased likelihood of developing cirrhosis and its complications, including liver cancer, and a prolonged survival.
Ascites, the accumulation of fluid in the abdominal cavity is most commonly caused by cirrhosis of the liver. Some of the other causes of ascites include portal hypertension, congestive heart failure, blood clots, and pancreatitis. The most common symptoms include increased abdominal girth and size, abdominal bloating, and abdominal pain. Treatment depends on the cause of ascites.
Whooping cough (pertussis) is highly contagious respiratory infection that is caused by the bacteria Bordetella pertussis. There are an estimated 300,000 plus deaths annually from whooping cough (pertussis). Whopping cough commonly affects infants and young children, but can be prevented with immunization with the vaccine. First stage whooping cough symptoms are a runny nose, sneezing, low-grade fever, a mild cough with the cough gradually becoming more severe. After one to two weeks, the second stage of whooping cough begins.
Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Tremor is the involuntary movements of one or more parts of the body. Causes of tremor include neurological disorders, neurodegenerative diseases, drugs, mercury poisoning, overactive thyroid and liver failure. There are several types of tremor. Treatment depends upon the type of tremor and availability of medications for the condition.
Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, E, F (not confirmed), and G) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease). The main nonviral causes of hepatitis are alcohol and drugs. Many patients infected with hepatitis A, B, and C have few or no symptoms of illness. For those who do develop symptoms of viral hepatitis, the most common are flu- like symptoms including: loss of appetite, nausea, vomiting, fever, weakness, tiredness, and aching in the abdomen. Treatment of viral hepatitis is dependant on the type of hepatitis.
Hyperglycemia is a serious health problem for diabetics. There are two types of hyperglycemia, 1) fasting, and 2)postprandial or after meal hyperglycemia. Hyperglycemia can also lead to ketoacidosis or hyperglycemic hyperosmolar nonketotic syndrome (HHNS). There are a variety of causes of hyperglycemia in people with diabetes. Symptoms include increased thirst, headaches, blurred vision, frequent urination and more. Treatment can be achieved through lifestyle changes or medications changes. Carefully monitoring blood glucose levels is key to prevention.
The liver is the largest solid organ in the body, and is actually an gland. The liver has a wide variety of critical functions such as manufacturing proteins and metabolizing fats and carbohydrates. The liver also eliminates harmful biochemical waste products from the body (alcohol, drugs, toxins). The liver secretes bile that aids in digestion. Examples of diseases of the liver include cirrhosis, hepatitis, cancer, and fatty liver. Symptoms of liver disease include bleeding, easy bruising, edema, fatigue, and jaundice.
Coma is the inability to waken or react to the surrounding environment. The Glasgow Coma Scale is frequently used to measure the depth of coma. Causes of coma include trauma, bleeding, edema, lack of oxygen, poisoning, or hypoglycemia. Prognosis for a patient in a coma depends on the cause of the coma.
Histoplasmosis is a disease caused by the Histoplasma capsulatum fungus. Symptoms and signs of this infection are fever, dry cough, chills, malaise, sweats, and abdominal pain. Transmission of the infection occurs when people inhale the spores. Most infections resolve on their own, and resistant infections are treated with itraconazole, ketoconazole, or amphotericin B.
AIDS is the advanced stage of HIV infection. Symptoms and signs of AIDS include pneumonia due to Pneumocystis jiroveci, tuberculosis, toxoplasmosis, seizures, weakness, meningitis, yeast infection of the esophagus, and Kaposi's sarcoma. Anti-retroviral therapy (HAART) is used in the treatment of AIDS.
Seizures are divided into two categories: generalized and partial. Generalized seizures are produced by electrical impulses from throughout the brain, while partial seizures are produced by electrical impulses in a small part of the brain. Seizure symptoms include unconsciousness, convulsions, and muscle rigidity.
Shigellosis is a disease caused by the Shigella bacteria. Bloody diarrhea, stomach cramps and fever are common symptoms. Mild infections usually resolve on their own. Antibiotics are used to treat more severe cases.
Reye's syndrome (RS, or Reye syndrome) is a sudden, sometimes fatal, disease of the brain with degeneration of the liver. Reye syndrome occurs in children and comes after the chickenpox or an influenza-type illness, is also associated with taking medications containing aspirin. Symptoms include vomiting, listlessness, irritability or combativeness, confusion, delirium, delusions, convulsions, and loss of consciousness. Treatment depends on early diagnosis and focuses on protecting the brain against irreversible damage by reducing brain swelling, reversing the metabolic injury, preventing complications in the lungs, and anticipating cardiac arrest.
Adult brain tumors are diseases in which cancer (malignant) cells begin to grow in the tissues of the brain. The brain controls memory and learning, senses (hearing, sight, smell, taste, and touch), and emotion. It also controls other parts of the body, including muscles, organs, and blood vessels. Tumors that start in the brain are called primary brain tumors.
Mad cow disease (or bovine spongiform encephalopathy [BSE]) is a fatal disease that attacks the central nervous system of adult cattle. Though the specific cause isn't known, it is speculated that infectious prions are the likely cause. Creutzfeldt-Jacob disease is found in people and is similar to BSE. A variation of this disease is thought to be caused by eating beef products from BSE-infected cattle.
Leigh's disease (Leigh's syndrome) is a rare genetic neurometabolic disorder. The symptoms of Leigh's disease include loss of appetite, loss of previously acquired motor skills, vomiting, irritability, and seizures. The most common treatment for Leigh's disease is thiamine or Vitamin B1. The prognosis for Leigh's disease is poor.
The kidneys are responsible for filtering waste products
from the blood. Dialysis is a
procedure that is a substitute for many of the normal duties of the kidneys. The
kidneys are two organs located on either side of the back of the abdominal
cavity. Dialysis can allow
individuals to live productive and useful lives, even though their
kidneys no longer work adequately. In the United States, there are
over 200,000 people who use dialysis techniques on an ongoing
basis.
Dialysis helps the body by performing the functions of failed
kidneys. The kidney has many roles.
An essential job of the kidney is to regulate the body's fluid balance. It does this by adjusting
the amount of urine that is excreted
on a daily basis. On hot days, the body sweats more. Thus, less water needs to
be excreted through the kidneys. On cold days, the body sweats less. Thus, urine output
needs to be greater in order to maintain the proper b...
