Yahoo! Messenger -- an instant messaging tool available for Windows, Mac and mobile devices -- enables users to be signed in to their account on multiple machines at the same time in the latest version of its software. The program also includes functionality for making calls to cellular phones and landlines, and for sending SMS text messages.
When a student has trouble with multiplication, it generally stems from never having memorized multiplication facts. Multiplication fact memorization is the key to successful multiplication of double-digit numbers. Students are either right-brain learners or left-brain learners. The left-brain learner easily memorizes math facts, while the right-brain learner struggles. The right-brain student needs a visual depiction, story or color to relate to the problem in order to remember the answer. Whether children are right-brain or left-brain learners, daily practice in mastering the facts can help solve their difficulty with multiplication.
Puppies quickly become members of the family once they are brought home. Puppies are prone to exploration and rough play, which can lend themselves to getting hurt. If your puppy hit its head hard on a surface or took a fall, you may be concerned that it has a concussion. If so, you should take the dog to the veterinarian as soon as possible for a check up, especially if it is exhibiting some of the warning signs of a concussion.
Trisomy 21 or Down syndrome is one of the most well-known genetic disorders. This condition results from what geneticists call chromosomal nondisjunction, when two chromosomes fail to separate during the process that makes sperm and egg cells. Although Down syndrome causes a variety of health and developmental problems, given good medical care there's no reason why people with Down syndrome can't enjoy a long, fulfilling life.
CyberKnife radiosurgery delivers very precise beams of radiation to eliminate benign or malignant tumors, while sparing surrounding healthy tissue. The decision to use CyberKnife certainly can provide advantages, but simply is not feasible for all patients. The optimal treatment plan for each patient may vary, depending several factors. Patients with advanced cancers may not always be ideal candidates. Medical staff members, such as oncologists or surgeons, serve as a valuable resource in determining suitable treatment.
MD stands for Doctor of Medicine, and this title is most likely applied to your current physician. When you have a medical condition, or when you think you might have an issue that needs to be discussed with your doctor, you may feel a disconnect when trying to communicate your concerns and symptoms. Doctors are very busy professionals, and to make sure the communication between yourself and your doctor is as effective as possible, you should always come to your appointments prepared.
An injury to the head such as a concussion requires a full neurological assessment. Such assessment is necessary to determine the extent of the injury. Once the assessment is complete and a diagnosis is made, the condition of the patient needs to be monitored by neuro checks. These checks provide a means of evaluating a patient's ongoing status, generally over the first 24 hours.
Speech loss can be devastating for anyone. However, there are other ways people can communicate without having to speak. It takes a great deal of effort by the patient to learn these new forms of communication, but it is worthwhile in the long run. There are many sources of assistance for those who have lost their speech.
Radiotherapy first began in the early 20th century, when medical student Emil Grubbe convinced his professor to allow him to irradiate Rose Lee, a patient suffering from advanced breast cancer. Radiotherapy, or radiation therapy, uses high-energy radiation to kill cancer cells and treat tumors, and between 50 and 60 percent of all cancer patients receive radiation treatment sometime during their disease, according to RadiologyInfo.org. Two inventions in the field of radiotherapy, the CyberKnife and Varian's Trilogy, have given oncologists a non-invasive way to treat tumors.
Apathy is related to the philosophy of Greek stoicism, but has evolved into more of a psychological term. Apatheia is the Greek word for stoicism, which was the intentional refusal of emotion. Both apathy and stoicism have benefits and detriments to a human's well-being, but the differences between the two are important. Stoicism is a specific philosophy, borne of a time in history. Apathy is a state of mind, and something that a person does not have immediate control over.
A scorpion uses its venom to capture prey, defend against possible threats and subdue mates during mating. Scorpion venom is comprised of a mixture of compounds including toxins that affect the nervous system. Each species of scorpion has a special mixture of venom that is deadly to its prey, which consists of lizards, mice and insects. However, approximately 25 of the 1,500 species of scorpion around the world possess venom potent enough to pose a danger to humans.
Cachexia is a condition where the patient loses mass amounts of weight and body fat. It is known as a wasting syndrome. Cancer patients, AIDS patients and those with anorexia can all develop cachexia. Other chronic diseases may also cause cachexia. Cachexia is different from starvation in that the body cannot absorb the nutrients that are ingested.
A seizure is an erratic electrical discharge within the brain that often causes a person to convulse uncontrollably. Children who have experienced or witnessed a seizure will have many fears. They may think they are going to die or worse, in their eyes, be made fun of by peers. Removing the cloud of mystery surrounding seizures by explaining them, will help the child to feel more at ease when dealing with a seizure.
Communicating with somebody who is mechanically ventilated can be a challenge because the tubes prevent the other person from speaking. There are, however, methods to improve communication with somebody in this condition. While there will be no verbal communication until the tube is removed, you can still communicate successfully with a mechanically ventilated individual.
Auditory hallucinations occur when a person perceives sound in the absence of external stimuli. Auditory hallucinations are heard rather then seen, felt, tasted or smelled, although a person can experience hallucinations through more than one sense simultaneously. The perceived stimuli can be a human voice, music or other sounds that seems to come from outside. These sounds feel and appear as real as the external stimuli we all perceive. The content of auditory hallucinations can reassure, threaten, command, warn or prove indecipherable.
Pre-employment physicals measure your overall health. These medical exams vary by employer, but they usually include a check of your vital signs, blood work and drug testing. An exam may also include more involved tests, such as an electrocardiogram (EKG) on your heart.
While you may feel comfortable talking to your mechanic about what is wrong your car, you may find it difficult to talk to your doctor about what is ailing you. Perhaps you feel at a loss for words to describe your condition, don't know what questions to ask, or even feel as if you have forgotten what you want answers to. You may even feel as though the doctor has not answered your queries sufficiently enough. But there are methods that will help make your encounters with your doctors more effective.
Epilepsy is a neurological condition that can make sufferers lose control of their bodily functions. The condition is caused by abnormal cell activity in the brain affecting the cerebral nerve. Sufferers experience seizures that alter their sensory and muscular functions. Seizures can also indicate a brain injury, lack of oxygen or high fever, not necessarily epilepsy. The Epilepsy Foundation states that almost three million Americans are affected by the condition, with approximately 200,000 new cases diagnosed each year.
Doctors, pharmacists and other practitioners sometimes need to convert units of measurement to adequately read diagnostic tests and prescribe medicine. This numerical data gets documented in several ways, such as in a patient's medical file or on a prescription form. Milliliters (mL) and cubic centimeters (cc) are two units that measure medicine, and they have a 1-to-1 ratio. However, many modern practitioners prefer mL over cc because bad handwriting can cause incorrect prescription dosages. Though the reasoning is serious, you can mathematically convert milliliters back to cubic centimeters with very little effort.
The Bobath technique, named after physiotherapist Berta Bobath and her husband Karel, a psychiatrist/neurophysiologist, is a method of neurotherapy for patients who have suffered an injury to the brain. Therapists using the technique look at the way any task is performed. This includes observing what patients are capable of completing alone and what they can do with differing amounts of help.
Acronyms often have multiple possible meanings in a variety of specialties, and PMLS is no exception. Be sure to check the context of your information for help determining which meaning of PMLS you need.
If you suffer from a condition such as multiple sclerosis that damages the myelin sheath protecting your nerve fibers, you will be pleased to know there are ways of repairing damage to myelin. Normally, the body can repair damage sustained by myelin sheaths, but if scarring occurs then healing can be difficult. Different approaches involving nutrition and nutraceutical treatments can help support myelin healing and regeneration and prevent scarring.
Neurointerventional radiologists are board-certified physicians who use minimally invasive technologies to treat blood vessel conditions related to the brain, spinal cord, head and neck. They also perform procedures on the bones and joints of the spine.
Length and severity of seizures can be used to diagnose several different forms of epilepsy. Epilepsy and sleep have a complex relationship due to the large amount of brain activity, especially during the rapid eye movement (REM) stage of sleep. There are a few types of epileptic disorders that triggers during sleep, and most of those begin during childhood. Some people experience these and don't know it. If you suspect that you or a loved one is experiencing seizures during sleep, schedule an appointment with a physician, neurologist or a sleep specialist.
According to neurology.org, training in neuro-oncology is available as a subspecialty for doctors trained in adult and pediatric neurology, and for medical oncologists. Training programs are available as either one or two year programs in neuro-oncology.
Multiple sclerosis is a degenerative autoimmune disease that affects the central nervous system. Symptoms vary widely among those diagnosed with MS, but common ailments include muscle weakness, numb limbs, blurred vision and even paralysis. There is no known cure for MS, so patients and their families are turning to alternative treatments, such as cranial electrotherapy stimulation, to attempt to treat it. Cranial electrotherapy stimulation passes electrical impulses across the base of the skull to change the brain's electrical activity. It has improved or eliminated symptoms for some MS patients but is still considered experimental by the mainstream medical community.
When an individual has a condition called foot drop---also called drop foot---his foot slaps against the surface on which he walks. Foot drop is a physical condition that results in a specific way of walking, which includes slapping the feet against the ground.
Commonly called Lou Gehrig's disease after the New York Yankee Hall of Famer who died from the illness in 1941, Amyotrophic Lateral Sclerosis is a progressive neurodegenerative disease that attacks the nerve cells in the brain and spinal cord. About 30,000 people in the United States suffer from ALS, whose symptoms include weakness and an eventual loss of strength and ability to move arms, legs or body. There is no cure for ALS, but you can receive treatments.
Although seizures affect the body by causing convulsions and bodily shaking, the National Institute of Neurological Disorders and Stroke states that they are actually symptomatic of a brain disorder. The uncontrollable body movements that accompany a seizure occur when the brain sends off faulty electrical signals. Although seizures are unpredictable and uncontrollable, recognizing the symptoms of a seizure can help you seek the treatment you need.
Many people struggle with remembering things, but a person's memory can improve with a little attention. With age, illness or just because life is busy and stressful, remembering essential dates, facts or functions can become overwhelming. There are several simple methods for improving memory. Eating a proper diet and stimulating the brain can improve memory. Playing games is the best exercise for the brain, and computers allow easy access to them.
The symptoms of neurological disorders in children vary depending on the specific disorder. Learn about specific neurological disorders and their symptoms with help from a pediatrician in this free video on children and pediatrics.
The CyberKnife is a technologically advanced piece of robotic radiotherapy equipment used to treat cancerous and non-cancerous tumors. According to CyberKnife manufacturer Accuray Incorporated, the noninvasive procedure accurately delivers beams of high-dose radiation directly to the tumor while sparing surrounding healthy tissues.
Aspartame is an artificial sweetener used in many foods and drinks, including Equal and NutraSweet. The FDA and 90 countries around the world approve of aspartame as a safe substance. However, medical evidence from the past and present suggest that it is a dangerous additive.
Multiple sclerosis (MS) is a debilitating, progressive and chronic disease that affects the central nervous system (the brain, optic nerves and spinal cord). MS is increasingly thought to be a disease of the immune system whereby the body’s own defenses attack body tissues, particularly myelin, the fatty tissue that coats nerve fibers. MS varies greatly from patient to patient. There is no cure, but new treatments are being developed, including treatment with human growth hormone (HGH).
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that attacks the nerve cells of a patient's brain and spinal cord. The disease is progressive, leading to the breakdown of motor neurons. Patients experience a rapid loss of muscle strength and control, not only in the limbs, but also in the muscles involved with primary functions such as breathing and swallowing. ALS is also known as Lou Gehrig's disease.
Musladin-Lueke Syndrome, often referred to as MLS, is a muscular disorder that affects many beagles. It usually shows up in some form early in life. MLS is a genetic disorder, but knowing more about MLS ahead of time can help pet owners properly deal with the problems that could eventually arise.
Use fun brain games for adults if you are easily distracted, need to improve your reaction speed, verbal fluency, arithmetic or memory recall. The human brain needs exercise just like our muscles. The NIH (National Institute of Health) has reviewed cognitive training studies and identified factors of brain exercises that may delay cognitive decline. Adding dietary changes, supplements and physical exercise is also suggested. Working memory training shows promising results in improving fluid intelligence in humans. The age-related cognitive studies done with mice provide information related to the cognitive decline in aging humans.
Reflex tests are part of the neurological examination given by a doctor when checking for a brain tumor. Doctors use various reflex tests to determine whether the nerve pathways traveling to the brain from elsewhere in the body are damaged. If there is pressure on one or more nerves by a brain tumor, the nervous system will not properly respond to the reflex tests.
Acoustic neuroma is a noncancerous tumor in the brain. Those who suffer from acoustic neuroma can experience hearing loss, facial numbness, loss of balance, and ringing in the ears, due to pressure on cranial nerves. The good news is that acoustic neuroma will not invade brain tissue. Treating the tumors can be done through radiation, monitoring and surgical removal. Although they are the most common types of brain tumors, the causes of acoustic neuroma have yet to be confirmed.
Multiple sclerosis is not that common--about 400,000 Americans are affected by it. But it is very noticeable to observers and extremely so to the patient. It gradually, and sometimes in a matter of a few years, “takes over” a patient’s coordination, speech, thinking--reducing these to tremors, slurring and confusion. Although medical science has made some progress in helping patients cope with this disease, it is incurable. At least so far. With stem cell therapy, perhaps a cure is near. But at what cost?
Electroconvulsive therapy (ETC), previously known as "electroshock treatment" or "electric shock therapy," involves sending electrical impulses into the brain to alter brain function. In the 1940s, doctors started using it systematically to treat mental illness, criminal behavior and memory loss but with mixed results. Today, electroconvulsive therapy is mainly used to treat depression and bipolar disorder, and the use of muscle relaxers and anesthetics during the procedure has made it less painful. However, the treatment can cause brain injury, which has lead many to regard it as inhumane.
Multiple Sclerosis, also referred to as MS, is an autoimmune disease that causes loss of vision, muscle control and balance and causes progressive numbness. MS attacks the spinal cord and brain, causing scar tissue to build up on one or both places. This scar tissue is called sclerosis, whereby MS gets its name. MS is more common in women than men and there is little understanding of what causes this debilitating disease.
Epilepsy is a neurological disorder that causes seizures. Seizures are unexpected brain glitches in which nerve cells, or neurons, fire at a much higher rate than normal. This causes external problems such as spasms and unconsciousness. Residential treatment facilities like the Mayo Clinic support epilepsy patients with a variety of treatments in a live-in setting.
Dermal sclerosis (also known as scleroderma or systemic sclerosis) is an auto-immune disease which affects the skin and other body tissues. This condition is chronic, but the symptoms can be controlled with treatment.
Idiopathic epilepsy is a group of epileptic disorders that have unknown origins and cannot be traced back to any certain area of the brain, according to C. P. Panayiotopoulos, MD, PhD, FRCP. The seizures cannot be explained by an underlying cause. It is a syndrome, meaning that it is a collection of symptoms from similar types of seizures. There are several classifications of idiopathic seizures.
Patients suffering from glioblastoma, a form of brain cancer, are becoming interested in a therapy that uses scorpion venom to shrink tumors. Scientists are mixing a radioactive isotope with an artificial version of the venom of Israeli yellow scorpions. The resulting medicine, TM-601, has shown some mild success in prolonging the lives of patients with glioblastomas.
Multiple aclerosis, or MS, is one of several disorders affecting the myelin casing that covers the nerve fibers around the spine. The damage done to this casing allows the delicate central nervous system to leak out fluid and triggers "misfires" along the nerve impulses and eventually nerve death. Several symptoms that appear along the neck and spine can be warning signs of multiple sclerosis.
According to the Mayo Clinic, about 2,000 children per year under the age of 16 are diagnosed with brain cancer in the United States. After leukemia, brain tumors are the second most common form of cancer in children. However, brain cancer in children is still quite rare, but it is important to recognize the signs and symptoms so your child receives prompt and proper care.
Multiple sclerosis (MS) is a disease affecting the central nervous system. The central nervous system consists of the brain, spinal cord and optic nerves. The signs, symptoms, progress and severity of the disease are unpredictable. MS is often difficult to recognize because it affects everyone differently. The disease paralyzes some people, while others show mild symptoms if any at all.
