What Does Unconscious Mean? Loss of Consciousness, Causes, Types, Symptoms, Stages – HealthyTipsAdvice

What happens when the body senses disappear when the ground slips away and the mind becomes blurred? Fainting is always dangerous, and there are times when loss of consciousness is a form of protecting the brain?

What is consciousness and the loss of consciousness?

When we put together all the thoughts, feelings, memories and perceptions – so all feelings, and when all mental processes are in connection with his “I” (self-aware) we get an overview of the term complex “conscious” that seems to distinguish us from animals.


But especially in recent years, is trying to establish states of consciousness and loss of consciousness among animals. Research is very difficult in terms of animals that have communication systems very different from ours. These states they can communicate that it causes pain and feelings and self-aware to what extent they influence the actions.

In medical practice, consciousness is verified by various methods to control attention, orientation, memory capacity, thinking and shareholders. This differentiates various states of consciousness (such as hard work, vigilance, scanning, relaxation, drowsiness, REM sleep, coma), of which toughness is defined as consciousness longest attention span and maximum tension, while the opposite is coma, as the lower state of consciousness, who works in just a few defense mechanisms.

In the case of loss of consciousness, the disorder can be long or short, depending on the cause. A brief episode of loss of consciousness, known as fainting, loss of control consists of physical and mental functions. Disorders of consciousness may vary depending on quantitative and qualitative nature. If quantitative disorders of consciousness, the consciousness is restricted increasingly more – in the case of confusion or sleepiness, the concerned is drowsy but not unconscious.

In the state of sopor, pre-coma or coma, loss of consciousness is very deep, and in the case can not be awakened despite the application of painful stimuli. The states of loss of consciousness, such as delirium and comatose states are accompanied by hallucinations, anxiety and irritability.

How are formed the episodes of loss of consciousness?

Thanks to the complex nerve, brain tolerates little deviation from a normal metabolic functioning state. To maintain this state constant blood supply to the brain, metabolism and cranial pressure form a highly sensitive control system, which detects changes and react immediately.

When installing a disorder in the system, all functions which include superior cranial – and consciousness with all the aspects that involve protection functions and reflexes vital functions such as breathing, heart rate or blood sugar level assurance the brain procrastinate when survival is no longer safe and the consequences consist in irreparable damage to the brain and body.

Unconsciousness – Causes and symptoms

What causes loss of consciousness?

In principle, movement cranial disorders such as those encountered in the case of head injuries or concussions that may occur as a result of bleeding or a blood vessel clogged differ from metabolic disorders with specific intoxication with drugs or medications or that can occur among people with diabetes, severe liver failure if the disease or thyroid gland.

Among other causes, brain function disorders play a role. Thus, an inflammation of the brain, a seizure, a brain tumor or a head injury suffered in an accident can be causes of loss of consciousness. In these cases, the excitation of the brain is so affected that in the brain only primitive functions are working .

Very often, short blackouts are caused by a short-term disturbance of blood supply to the brain when one of the nerve centers that manage heart function is affected. These control centers, among others, the peripheral blood pressure – when blood pressure drops strongly, the brain is irrigated properly and get into “emergency mode”.

These short losses of consciousness are called syncope depending -in affected nerve center there vasovagal syncope, micturition syncope (when syncope occurs during urination), cough syncope, orthostatic syncope (loss of consciousness when installs when the patient rises from vertical horizontal) or Adam-Stokes attacks, when our heart pacemaker biological pauses momentarily.

How to show unconsciousness?

By extending disorder, all mental processes are slowed down until consciousness is so limited that it is not possible any perception of the senses and conscious control over various functions of the body disappears: thus, the muscles relax.

In hospitals always distinguishes between cases where the patient was collapsed and the unconsciousness that was so short, without affecting all levels of perception, allowing avoid a crash. Especially if syncope, generalized convulsion of states such as epileptic crises of hypoglycemia in diabetics or increased intracranial pressure, which can occur in accidents, collapse is typical.

There are forms of loss of consciousness without downtime: these include so-called abscesses and attacks complex-focal, so forms of epilepsy that do not involve a state generalized convulsive, but a disturbance short of consciousness, or a short disorder irrigation brain by a blood clot, so-called TIA (transient ischemic attack), which can precede a concussion, like migraines, during which patients perceive everything through the haze.

After short episodes of loss of consciousness, they remember those affected as they were made black in front and they felt a malaise. Patients who suffer from migraines, describing similar symptoms felt an aura or visual field on the outskirts of feeling gaze through a tunnel. In the case of longer episodes of loss of consciousness, brain function is interrupted for longer and installs amnesia, a memory gap, which depends on the cause loss of consciousness may take several days.

Unconsciousness – treatment

How can act against losing consciousness?

Personal: When you feel like going to faint, try to bring your body into a position from which a possible injury to be as small: sit on the floor and raise your legs to allow better irrigation of the brain with blood and avoid whenever possible, to fainting. Tell your doctor about when loss of consciousness, even though it was a short one: could indicate a heart disorder or brain, or even of diabetes or a brain tumor!

For other people: If you notice that a person has lost consciousness, you place it in a stable position, checking breathing and pulse. Notify emergency medical service because the loss of consciousness is always necessary to establish the cause. The emergency medical team will apply extensive first-aid measures and we will carry on the concerned hospital where he will try to establish the cause of loss of consciousness.
