Coma, from the Greek word " koma, " meaning deep sleep, is a state of extreme unresponsiveness, in which an individual exhibits no voluntary movement or behavior. Furthermore, in a deep coma, even painful stimuli (actions which, when performed on a healthy individual, result in reactions) are unable to affect any response, and normal reflexes may be lost.

|
|
Dizziness is classified into three categories- vertigo, syncope, and nonsyncope nonvertigo. Each category has a characteristic set of symptoms, all related to the sense of balance.

As a disorder, dizziness is classified into three categories: vertigo, syncope, and nonsyncope nonvertigo. Each category has its own set of symptoms, all related to the sense of balance.

|
Dizziness is a general term that describes sensations of imbalance and unsteadiness, such as vertigo, mild turning, imbalance, and near fainting or fainting. Feelings of dizziness stem from the vestibular system, which includes the brain and the parts of the inner ear that sense position and motion, coupled with sensory information from the eyes, skin, and muscle tension.
|
|
Fainting is a temporary loss of consciousness due to a drop in blood flow to the brain. The episode is brief (lasting less than a couple of minutes) and is followed by rapid and complete recovery. You may feel lightheaded or dizzy before fainting. A longer, deeper state of unconsciousness is often called a coma.
|
|
Fainting is a temporary loss of consciousness, weakness of muscles, and inability to stand up, all caused by sudden loss of blood flow to the brain. Fainting is a relatively common symptom caused by a variety of problems relating to changes in blood pressure.
|
|
|
Fainting is loss of consciousness caused by a temporary lack of oxygen to the brain. Known by the medical term " syncope, " fainting may be preceded by dizziness , nausea, or a feeling of extreme weakness.
|
|
|
If your blood pressure drops too low, your brain may not get enough oxygen-rich blood. Your body responds by losing consciousness briefly. You also slump or fall down. This problem is called syncope, fainting, or a blackout.
|
|
When the brain receives conflicting signals, or when there is a problem with blood flow, dizziness or fainting can occur.

Unconsciousness is when a person is unable to respond to people and other stimuli around him or her. Often, this is called a coma or being in a comatose state. Other changes in awareness can occur without becoming unconscious. Medically, these are called "Altered Mental Status" or "Changed Mental Status." They include sudden confusion, disorientation, or stupor. Unconsciousness and any other SUDDEN change in mental status must be treated as a medical emergency. If someone is awake but less alert than usual, ask a few simple questions -- What is your name? What is the date? How old are you? If the person doesn't know or answers incorrectly, then his or her mental status is diminished.

A normal breathing rate for an adult at rest is 8 to 16 breaths/minute. For an infant, a normal rate is up to 44 breaths/minute. Tachypnea is a medical term that your doctor would use to describe your breathing if it is too fast, particularly if you have rapid, shallow breathing due to an associated lung disease or other medical cause. In contrast, the term hyperventilation is usually used if you are taking rapid, deep breaths because of anxiety or panic. The terms may be used interchangeably, however.

A seizure is a sudden change in behavior characterized by changes in sensory perception (sense of feeling) or motor activity (movement) due to an abnormal firing of nerve cells in the brain.

A temporary series of uncontrollable muscle spasms brought on by unusual electrical activity in the brain. Also known as convulsion, clonic seizure, or tonic-clonic seizure.

|
Children with epilepsy may have seizures only once in a while, or every day. Though seizures can be scary for parents and caregivers, they aren’t painful and are usually brief.
