Delirium is usually temporary, but older people who experience delirium may suffer permanent damage. It is believed that delirium is linked to dementia, but more research must be done before any conclusions can be made.

Delirium is a medical condition characterized by a vascillating general disorientation, which is accompanied by cognitive impairment, mood shift, self-awareness, and inability to attend (the inability to focus and maintain attention). The change occurs over a short period of time— hours to days— and the disturbance in consciousness fluctuates throughout the day.

A headache is pain or discomfort in the head, scalp, or neck. Serious causes of headaches are extremely rare. Most people with headaches can feel much better by making lifestyle changes, learning ways to relax, and occasionally by taking medications. See also: Cluster headache; Migraine; Tension headache.

A headache involves pain in the head which can arise from many disorders or may be a disorder in and of itself.

Headache is a pain in the head and neck region that may be either a disorder in its own right or a symptom of an underlying medical condition or disease. The medical term for headache is cephalalgia. Headaches are one of the most common and universal human ailments, described in the Bible as well as in medical writings from ancient Egypt, Babylonia, Greece, Rome, India, and China. Severe chronic headaches were once treated by the oldest known surgical procedure, known as trepanning or trephining, in which the surgeon drilled a hole as large as 1–2 in diameter in the patient's skull without benefit of anesthesia. Evidence of trepanning has been found in skulls from Cro-Magnon people that are about 40,000 years old.

Fever is the temporary increase in the body's temperature, in response to some disease or illness. A child has a fever when their temperature is at or above one of these levels: 100.4 F (38 C) measured in the bottom (rectally; 99.5 F(37.5 C) measured in their mouth (orally; 99 F (37.2 C) measured under their arm (axillary. An adult probably has a fever when their temperature is above 99 - 99.5 ?F (37.2 - 37.5 ?C), depending on what time of the day it is. See also: Temperature measurement; Heat emergencies.

A fever is any body temperature elevation over 100.4°F (38°C).

Detailed information on fevers in children

A fever is a special cause for concern in infants younger than 3 months of age. Parents and caregivers should be most concerned with changes in eating or sleeping habits, coughing, pain or other marked changes.

Fever is defined as an abnormally high body temperature or a regulated rise to a new set point of body temperature. While a body temperature above 100°F(37.8°C) is considered to be a fever by some clinicians, a significant fever is usually defined as an oral temperature of 102°F (39°C) or a rectal temperature of 103°F(39.5°C). Fever is a sign of inflammation and represents the body's response to microbial invasion or to a disease process. Hyperthermia is defined as abnormally high body temperature caused by disruption of the body's thermoregulatory mechanisms. Hyperthermia occurs when the body's metabolic heat production or environmental heat load exceeds the normal heat loss capacity (or when normal heat loss is impaired).

A fever is any body temperature elevation over 100°F (37.8°C).

Normal body temperature varies somewhat from one individual to another but displays a general range and pattern around the "normal" temperature of 98.6°F. Early morning body temperature may be as low as 97°F, and as high as 99.3°F in the afternoon hours yet still be considered normal. Higher temperatures may be observed in healthy people, but an abnormal elevation (pyrexia) is classified as hyperthermia , or fever. Fever results from a failure in the body's ability to regulate and dissipate heat. Any fever presents an unpleasant and uncomfortable state for the patient. Fever may cause the patient to experience fatigue , chills, sweats, nausea, and—in some cases—life-threatening conditions. When fevers occur in the elderly or the very young, the effects can be more harmful than in individuals who fall between those two age groups. The elderly may experience poor blood circulation, heart failure, an irregular heartbeat, or mental episodes. Children may lapse into fever-induced seizures. It is possible to treat fever with lukewarm sponge baths or bathing, removing excess clothing or bedding, and increasing the patient's fluid intake; however an important treatment is medication that lowers the body temperature to its normal range.

An elevated body temperature. While the standard for normal body temperature is 98.6°F (37°C), normal body temperatures actually fluctuate within a range of one to two degrees, making it impossible to formulate a precise definition of fever based on a specific temperature. Children's temperatures are generally higher than those of adults and fluctuate more widely. They may vary depending on the time of day, the child's emotional state or level of physical activity, the amount of clothing worn, or the surrounding room temperature. In general, temperatures under 100°F (37.7°C) are considered "subfebrile" (i.e., not indicating fever). Rectal temperatures of up to 100.4°F (38°C) may be considered normal. A part of the brain called the hypothalamus acts as the body's thermostat, keeping its temperature at or close to 98.6°F (37°C). When there is an infection (or certain other types of disease), the body's white blood cells produce specific proteins (endogenous pyrogens) that reach the brain through the bloodstream and stimulate the hypothalamus, which signals the body to increase its metabolic rate and consume oxygen faster, resulting in a higher body temperature. Fever is one of the ways the body defends itself against infections. It is commonly caused by viral and bacterial infections, including colds, earaches, and flu. When fever is present, the production of infection-fighting white blood cells is increased, and their effectiveness is enhanced. More serious potential causes of fever include pneumonia, urinary tract infections, appendicitis, and meningitis. Fever can also be caused by non-infectious conditions that produce inflammation—such as juvenile rheumatoid arthritis, Crohn's disease, and lupus—as well as overexertion, dehydration, allergic reactions, insect bites and stings, and toxic reactions. A child's temperature can be taken in several ways. Rectal temperatures are about half a degree higher than oral ones. A rectal reading is considered more accurate than an oral one, which may be affected by previously eaten hot or cold foods or by a child's breathing. Underarm temperatures are considered reliable for young infants, and new electronic thermometers can measure temperature through the ear. Although fever is generally a cause for concern among parents, high fevers are not necessarily a sign of serious illness. Unlike adult temperatures, the level of a child's temperature does not necessarily indicate the severity of an illness. A mild cold may produce a fever as high as 105°F (40.5°C), while the fever accompanying pneumonia may only be 100°F (37.7°C). The temperatures of newborn infants are particularly unreliable because the baby's temperature control mechanism is not yet adequately developed. Although fevers are generally not dangerous, they are treated because they cause discomfort and can prevent children from getting the sleep and nourishment they need in order to get well. Aspirin was the medication most commonly used to lower fevers until 1980, when researchers found that the use of aspirin to treat children's fevers caused by influenza and chicken pox was associated with Reye's syndrome, a dangerous condition that causes liver impairment and brain damage and can result in coma and eventual death. Since then, acetaminophens (sold under such brand names as Tylenol) have become the most widely recommended drugs for treating fever in children. Acetaminophens, which are available in liquid form, tablets and capsules for oral use, and as suppositories, are effective in treating fever but do not share aspirin's inflammation-reducing properties. Ibuprophen (Advil, Nuprin, etc.) is an effective fever reducer that is also an anti-inflammatory. However, it has not been on the market as long as acetaminophens and has been known to produce allergic and gastrointestinal side effects. A fever can also be reduced one or two degrees by sponging a child wi

One minute you're hot; the next, you're chilled and your teeth chatter. You've got a fever. But look on the bright side: Fever seems to serve a helpful function in the body.

Buying a thermometer isn't as easy as it used to be. You face an array of choices. But the decision doesn't have to be hard. Like temperature, it's a matter of degrees.

Most medical professionals agree a fever by itself is not an illness; it is a symptom of an underlying problem. Fevers actually can be a positive sign the body is fighting an infection. However, a fever can cause discomfort for a child.

A fever is a way for the body to fight infection. But it may also be a sign of a serious illness, especially in children younger than 3 months and children who haven't been immunized. Know when to seek medical care for your child.

The best way to take an infant's temperature is rectally with a digital thermometer (never use a glass mercury thermometer). Taking the temperature under the arm, or using an ear thermometer, is less exact.

Use a digital thermometer to take your child's temperature; never use a glass mercury thermometer. Most children aged three years and older can hold a thermometer under their tongue. If your child is younger than that, or you're having difficulty with the oral method, talk to your doctor about the best way to take his temperature.

Hyperthermia involves raising the body's core temperature as a means of eradicating tumors. The treatment simulates fever . Some therapies actually bring on fever through the introduction of fever-causing organisms, while others raise body temperature by directly heating the blood.

Hyperthermia is the use of therapeutic heat to treat various cancers on and inside the body.

Children can become cranky, fussy or irritable for many reasons. Often it's because they're hungry or just tired. But sometimes irritability can be a sign of illness in children.

Pain is a universal human experience. The International Association for the Study of Pain (IASP) defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage." Pain may be a symptom of an underlying disease or disorder, or a disorder in its own right. At the same time that pain is a universal experience, however, it is also a complex one. While the physical sensations involved in pain may be constant throughout history, the ways in which humans express and treat pain are shaped by their respective cultures and societies. Since the 1980s, research in the neurobiology of pain has been accompanied by studies of the psychological and sociocultural factors that influence people's experience of pain, their use of health care systems, and their compliance with various treatments for pain. As of 2003, the World Health Organization (WHO) emphasizes the importance of an interdisciplinary approach to pain treatment that takes this complexity into account.

Expert-reviewed information summary about pain as a complication of cancer or its treatment. Approaches to the management and treatment of cancer-associated pain are discussed.

Pain, medically termed "nociception," is a response to noxious stimuli that is conveyed to the brain by sensory neurons . The discomfort signals actual or impending injury to the body. However, pain is more than a sensation, or the physical awareness of pain; it also includes perception, the subjective interpretation of the discomfort. Perception gives information on the pain's location, intensity, and something about its nature. The various conscious and unconscious responses to both sensation and perception, including the emotional response, add further definition to the overall concept of pain.

Fatigue is a feeling of weariness, tiredness, or lack of energy.

Fatigue is physical and/or mental exhaustion that can be triggered by stress , medication, overwork, or mental and physical illness or disease.

Boosting Your Energy provides information on the causes and treatments of persistent fatigue. Includes information on aging and energy, eating for energy, and boosting your energy.

Fatigue may be defined as a subjective state in which one feels tired or exhausted, and in which the capacity for normal work or activity is reduced. There is, however, no commonly accepted definition of fatigue when it is considered in the context of health and illness. This lack of definition results from the fact that a person's experience of fatigue depends on a variety of factors. These factors include culture, personality, the physical environment (light, noise, vibration), availability of social support through networks of family members and friends, the nature of a particular fatiguing disease or disorder, and the type and duration of work or exercise . The experience of fatigue associated with disease will be different for someone who is clinically depressed, is socially isolated, and is out of shape, as compared to another person who is not depressed, has many friends, and is aerobically fit.

Fatigue may be defined as a subjective state in which one feels tired or exhausted, and in which the capacity for normal work or activity is reduced. There is, however, no commonly accepted definition of fatigue when it is considered in the context of health and illness. This lack of definition results from the fact that a person's experience of fatigue depends on a variety of factors. These factors include culture; personality; the physical environment (light, noise, vibration); availability of social support through networks of family members and friends; the nature of a particular fatiguing disease or disorder; and the type and duration of work or exercise. For example, the experience of fatigue associated with disease will be different for someone who is clinically depressed, is socially isolated, and is out of shape, as compared to another person who is not depressed, has many friends, and is aerobically fit. Fatigue is sometimes characterized as normal or abnormal. For example, the feeling of tiredness or even exhaustion after exercising is a normal response and is relieved by resting; many people report that the experience of ordinary tiredness after exercise is pleasant. Moreover, this type of fatigue is called acute since the onset is sudden and the desired activity level returns after resting. On the other hand, there is a kind of fatigue that is not perceived as ordinary; that may develop insidiously over time; is unpleasant or seriously distressing; and is not resolved by rest. This kind of fatigue is abnormal and is called chronic . Some researchers regard fatigue as a defense mechanism that promotes the effective regulation of energy expenditures. According to this theory, when people feel tired they take steps to avoid further stress (physical or emotional) by resting or by avoiding the stressor. They are then conserving energy. Since chronic fatigue is not normal, however, it is an important symptom of some mental disorders; of a variety of physical diseases with known etiologies (causes); and of medical conditions that have no biological markers although they have recognizable syndromes (patterns of symptoms and signs). Fatigue is sometimes described as being primary or secondary. Primary fatigue is a symptom of a disease or mental disorder, and may be part of a cluster of such symptoms as pain, fever, or nausea. As the disease or disorder progresses, however, the fatigue may be intensified by the patient's worsening condition, by the other disease symptoms, or by the surgical or medical treatment given to the patient. This subsequent fatigue is called secondary.

Fatigue is a feeling of exhaustion or loss of strength. The duration of fatigue for a patient with cancer has been found to last from one to two times the length of time between diagnosis and completion of treatment, so it is common for fatigue to persist beyond a patient's treatment regimen.

Answering the questions in this tool will help you understand more about the possible causes of diarrhea in children, and will help you decide when to call your doctor.

To most persons, diarrhea means an increased frequency or softer consistency of bowel movements; however, the medical definition is more exact than this. Diarrhea best correlates with an increase in stool weight; stool weights above 300 g per day generally indicates diarrhea. This is mainly due to excess water, which normally makes up 60-85% of fecal matter. In this way, true diarrhea is distinguished from diseases that cause only an increase in the number of bowel movements (hyperdefecation), or incontinence (involuntary loss of bowel contents). Diarrhea is also classified by physicians into acute, which lasts one to two weeks, and chronic, which continues for longer than 23 weeks. Viral and bacterial infections are the most common causes of acute diarrhea.

Nonspecific back pain refers to pain in the back due to an unknown cause. See also: Low back pain
