Generalized seizures are a result of abnormal neuronal activity on both sides of the brain. These seizures may cause loss of consciousness, falls, or massive muscle spasms.
There are many kinds of generalized seizures. In absence seizures, the person may appear to be staring into space and/or have jerking or twitching muscles. These seizures are sometimes referred to as
petit mal seizures, which is an older term. Tonic seizures cause stiffening of muscles of the body, generally those in the back, legs, and arms. Clonic seizures cause repeated jerking movements of muscles on both sides of the body. Myoclonic seizures cause jerks or twitches of the upper body, arms, or legs. Atonic seizures cause a loss of normal muscle tone. The affected person will fall down or may drop his or her head involuntarily. Tonic-clonic seizures cause a mixture of symptoms, including stiffening of the body and repeated jerks of the arms and/or legs as well as loss of consciousness. Tonic-clonic seizures are sometimes referred to by an older term:
grand mal seizures.
Not all seizures can be easily defined as either focal or generalized. Some people have seizures that begin as focal seizures but then spread to the entire brain. Other people may have both types of seizures but with no clear pattern.
Society's lack of understanding about the many different types of seizures is one of the biggest problems for people with epilepsy. People who witness a non-convulsive seizure often find it difficult to understand that behavior which looks deliberate is not under the person's control. In some cases, this has led to the affected person being arrested or admitted to a
psychiatric hospital. To combat these problems, people everywhere need to understand the many different types of seizures and how they may appear.
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.
A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous
system. When only the skin is involved, the condition is called discoid lupus.
When internal organs are involved, the condition is called systemic lupus
erythematosus (SLE).
Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
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.
Group B strep are bacteria called Streptococcus agalactiae that may sometimes cause infections both in a pregnant woman and her newborn. Symptoms include fever, seizures, heart rate abnormalities, breathing problems, and fussiness. Intravenous antibiotics are used to treat group B strep infections.
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.
Malaria is an infectious disease transmitted by the bite of an infected Anopheles mosquito. Symptoms of malaria include chills, pain, fever, and sweating. Though mild cases of malaria can be treated with oral medication, severe cases require intravenous drug treatment and fluids.
Rhabdomyolysis is a rapid deterioration and destruction of skeletal muscle. Some of the causes of rhabdomyolysis include severe burns, muscle trauma, coma, seizures, electrolyte imbalance, medications (statins), viruses, bacteria. Treatment of rhabdomyolysis depends on the cause.
Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the ventricles of the brain. The fluid is often under increased pressure and can compress and damage the brain. Symptoms of hydrocephalus vary with age, progression of the disease, and individual tolerance to the condition. Hydrocephalus is most often treated by surgery in which a shunt system is inserted.
Huntington's disease is the result of degeneration of neurons in areas of the brain. Huntington's disease is an inherited disorder. Early symptoms include mood swings, apathy, depression, and anger uncharacteristic of the individual. Judgement, memory, and other cognitive functions may become impaired. Presymptomatic testing is available for individuals who have a family history of Huntington's disease. Treatment includes medication and therapy for symptoms.
Pulmonary edema (swelling or fluid in the lungs) can either be caused by cardiogenic causes (congestive heart failure, heart attacks, abnormal heart valves) or noncardiogenic causes such as ARDS, kidney failure, high altitude, pneumothorax, pleural effusion, aspirin overdose, pulmonary embolism, and infections. The treatment of pulmonary edema depends on the cause of the condition.
Encephalopathy means brain disease, damage, or malfunction. Causes of encephalopathy are varied and numerous. The main symptom of encephalopathy is an altered mental state. Other symptoms include lethargy, dementia, seizures, tremors, and coma. Treatment of encephalopathy depends on the type of encephalopathy (anoxia, diabetic, Hashimoto's, hepatic, hyper - hypotensive, infectious, metabolic, infections, uremic, or Wernicke's) are examples of types of encephalopathy.
A number of vital tasks carried out during sleep help maintain good health and enable people to function at their best. Sleep needs vary from individual to individual and change throughout your life. Not getting enough sleep can hurt memory performance, health, and your mood.
Concussion is a short-lived loss of brain function that is due to head trauma. There are two types of concussion, simple and complex. Symptoms of concussion include headache, nausea, dizziness, dazed feeling, irritability, visual symptoms. Physical signs include poor concentration, emotional changes, slurred speech, and personality changes. Concussion is diagnosed with physical examination and testing. Treatment for concussion in general are treatment for control of the symptoms, and time.
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
Listeria is a type of bacteria that can cause food poisoning. Listeriosis symptoms include diarrhea, nausea and fever. Pregnant women are 20 times more likely than other healthy adults to get listeriosis. Listeria infection is treated with antibiotics.
Cancers that form from brain tissue are called primary brain tumors. Brain tumors may be malignant (brain cancer) or benign. Certain risk factors, such as working in an oil refinery, as a chemist, or embalmer, increase the likelihood of developing brain cancer. Symptoms include headaches, weakness, seizures, difficulty walking, blurry vision, nausea and vomiting, and changes in speech, memory, or personality. Treatment may involve surgery, radiation therapy, or chemotherapy.
Toxoplasmosis (toxo) is a parasitic infection that causes flulike symptoms, swollen lymph nodes, and muscle aches and pains that may last from a few days to several weeks. Toxoplasmosis can be contracted by touching the hands to the mouth after gardening, cleaning a cat's litter box, or anything that came into contact with cat feces. Toxoplasmosis can also be contracted by eating raw or partly cooked meat, especially pork or lamb, or touching the hands to the mouth after contact with raw or undercooked meat.
Cerebral palsy (CP) is an abnormality of motor function and postural tone acquired at an early age (even before birth). Cerebral palsy is generally caused by brain trauma. Types of cerebral palsy include: spastic, choreoathetoid, and hypotonic. There is no cure for cerebral palsy, and treatment is generally managing the symptoms of the condition.
Encephalitis is a brain inflammation that causes sudden fever, vomiting, headache, light sensitivity, stiff neck and back, drowsiness, and irritability. Meningitis is an infection that causes inflammation of the meninges that surround the brain and spinal cord. Symptoms of meningitis include high fever, headache, nausea, vomiting, and stiff neck.
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.
Autism in children and adults is a developmental disorder, characterized by impaired development in communication, social interaction, and behavior. Autism is classified as a pervasive developmental disorder (PDD), which is part of a broad spectrum of developmental disorders affecting young children and adults. There are numerous theories and studies about the cause of autism. The treatment model for autism is an educational program that is suitable to an individual's developmental level of performance. There is no "cure" for autism.
A brain hemorrhage is a type of stroke caused when an artery bursts in the brain, causing localized bleeding in the surrounding tissue. Causes of brain hemorrhage include aneurysm, liver disease, brain tumor, head trauma, high blood pressure, and blood vessel abnormalities. Symptoms include sudden severe headache, nausea, vomiting, loss of balance, tingling, numbness, vision changes, loss of consciousness, and loss of fine motor skills. Treatment depends upon the cause, location, and size of the brain hemorrhage.
In the United States, head injuries are one of the most common causes of death and disability. Head injuries due to bleeding are generally classified by the location of the blood within the scull, these include: epidural hematoma, subdural hematoma, subarachnoid bleed, intracranial bleed, sheer injury, edema, and skull fracture. Some common symptoms of a head injury include: vomiting, bleeding from the ear, speech difficulties, paralysis, difficulty swallowing, and body numbness. Treatment of a head injury depends on the type and severity of the injury.
Novel H1N1 influenza A virus infection (swine flu) is an infection that generally is transferred from an infected pig to a human, however there have been reported cases where infection has occured with no contact with infected pigs. Symptoms of swine flu are "flu-like" and include fever, cough, and sore throat. Treatment is generally with the antibiotics oseltamivir (Tamiflu) or zanamivir (Relenza).
Trichinosis is a food-borne disease caused by ingesting parasites (roundworms) in undercooked pork or wild-game meat. Symptoms of trichinosis include diarrhea, nausea, muscle aches, itching, fever, chills, and joint pains. Trichinosis usually resolves without treatment, but more severe cases are treated with thiabendazole, albendazole, or mebendazole.
