Top 8 Unconscious Causes

  1. 1.Stroke or Tia (Transient Ischemic Attack)

    A stroke is a medical emergency. Strokes happen when blood flow to the brain is stopped.

    You needs to go to the hospital by ambulance or as soon as possible. The longer you wait, the fewer treatment options available and the worse the outcome.

    Rarity:
    Common
    Top Symptoms:
    dizziness, new headache, arm numbness, being severely ill, leg numbness
    Symptoms that never occur with stroke or tia (transient ischemic attack):
    bilateral weakness
    Urgency:
    Emergency medical service
  2. 2.Stroke or Tia (Transient Ischemic Attack)

    A stroke is a medical emergency. Strokes happen when blood flow to the brain is stopped.

    Call 911 immediately. The longer you wait, the fewer treatment options available and the worse the outcome.

    Rarity:
    Common
    Top Symptoms:
    dizziness, new headache, being severely ill, stiff neck, arm weakness
    Symptoms that never occur with stroke or tia (transient ischemic attack):
    bilateral weakness
    Urgency:
    Emergency medical service
  3. 3.Sudden Cardiac Arrest

    Sudden cardiac arrest (SCA) occurs when the heart develops an irregular beat that causes it to stop beating.

    You should go to the ER immediately since the longer the heart goes without blood, the worse the irreversible damage will be. Hurry!

    Rarity:
    Rare
    Top Symptoms:
    being severely ill, constant chest pain, current loss of consciousness, pale skin all over
    Symptoms that always occur with sudden cardiac arrest:
    current loss of consciousness
    Urgency:
    Emergency medical service
  4. 4.Generalized Tonic - Clonic Seizure

    A seizure is a short burst of uncontrolled electrical activity in the brain. A generalized tonic-clonic seizure affects both halves of the brain, and comes in two phases (tonic and clonic). The tonic phase is characterized by rigidity of all muscles and loss of consciousness. Saliva may escape the mouth, and the bladder may contract, releasing urine. The clonic phase follows, when the body appears to shake. This may last from seconds to minutes. The person gradually regains consciousness. A seizure may be caused by an underlying disease such as epilepsy, or by triggers such as heavy drinking, drugs, or anxiety.

    Call 911 immediately for an ambulance.

    Rarity:
    Rare
    Top Symptoms:
    being severely ill, brief fainting episode, confusion/disorientation after returning to consciousness, not having protected the body during the fall, loss of consciousness without remembering
    Symptoms that always occur with generalized tonic-clonic seizure:
    being severely ill, loss of consciousness without remembering, confusion/disorientation after returning to consciousness
    Urgency:
    Emergency medical service

  5. 5.Aspiration Pneumonia

    Aspiration Pneumonia occurs when food, saliva, liquids, or vomit is breathed into the lungs or airways leading to the lungs, causing an infection.

    Going to your doctor is important, since diagnosing Aspiration Pneumonia requires a chest x-ray and a blood test. Given the possibility of the infection worsening, starting antibiotic treatment as soon as possible is really key.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, cough, shortness of breath, fever, coughing up green or yellow phlegm
    Urgency:
    Hospital emergency room
  6. 6.Intracerebral Hemorrhage

    Intracerebral hemorrhage occurs when a diseased blood vessel within the brain bursts, allowing blood to leak inside the brain. (The name means within the cerebrum or brain).

    Call 911 immediately for an ambulance now. This is a life-threatening medical condition which needs to be treated in an intensive care unit (ICU). Blood pressure medication will be administered, as well as medications to prevent seizures and blood clots. Emergency surgery may be performed to decrease the size of the bleed and prevent pressure from building up in the brain and destroying tissue.

    Rarity:
    Rare
    Top Symptoms:
    nausea, new headache, severe headache, vomiting, stiff neck
    Urgency:
    Emergency medical service
  7. 7.Stroke or Tia (Transient Ischemic Attack)

    A stroke is a medical emergency. Strokes happen when blood flow to the brain is stopped.

    You needs to go to the hospital by ambulance or as soon as possible. The longer you wait, the fewer treatment options available and the worse the outcome.

    Rarity:
    Rare
    Top Symptoms:
    being severely ill, new headache, stiff neck, dizziness, vision changes
    Symptoms that never occur with stroke or tia (transient ischemic attack):

  8. 8.Subarachnoid Hemorrhage
