What causes transient loss of consciousness?
The most common causes of syncopal TLOC include: (1) cardiogenic syncope (cardiac arrhythmias, structural cardiac diseases, others); (2) orthostatic hypotension (due to drugs, hypovolemia, primary or secondary autonomic failure, others); (3) neurally mediated syncope (cardioinhibitory, vasodepressor, and mixed forms).
What does TLoC mean in medical terms?
This guideline is about the assessment, diagnosis and specialist referral of adults and young people (aged 16 and older) who have experienced a blackout (the medical term for this is ‘transient loss of consciousness’ or TLoC for short).

What caused me to blackout?
The most common cause of blacking out is fainting. Other causes include epileptic seizures, syncope due to anxiety (psychogenic pseudosyncope) and other rare causes of faints. Other causes of blacking out may be due to low blood sugar (hypoglycaemia) and lack of oxygen (hypoxia) from a variety of causes.
How do you know your level of consciousness?
The tool we use to assess the level of consciousness is the Glasgow Coma Scale (GCS). This tool is used at the bedside in conjunction with other clinical observations and it allows us to have a baseline and ongoing measurement of the level of consciousness (LOC) for our patients.
What happens to your body when you lose consciousness?
The stressful event stimulates a bodily reflex called the vasovagal reaction. The heart slows down and pumps less blood, so blood pressure drops. Then the brain doesn’t get enough oxygenated blood, and the person faints.
What is presyncope syndrome?
Basically, presyncope (pre-sin-co-pee) is the sensation that you’re going to faint. You might feel lightheaded and weak, among other symptoms, but you don’t actually pass out. You typically feel better within a few minutes. If you do faint and regain consciousness, that’s called syncope.
What is atypical syncope?
Atypical forms of reflex syncope include those situations in which reflex syncope occurs with uncertain or absent triggers. As such, it is a diagnosis of exclusion and usually needs to be confirmed by tilt testing.
What is the level of consciousness in psychology?
Level of consciousness ( LOC) is a measurement of a person’s arousability and responsiveness to stimuli from the environment. A mildly depressed level of consciousness or alertness may be classed as lethargy; someone in this state can be aroused with little difficulty.
What is transient loss of consciousness (Tod)?
Transient loss of consciousness: sudden onset, complete loss of consciousness of brief duration with relatively rapid recovery; distinct from persistent loss of consciousness or coma in its causes, assessment and management
What is an altered level of consciousness?
Altered or abnormal levels of consciousness describe states in which a person either has decreased cognitive function or cannot be easily aroused. Most medical conditions affect the brain and impair consciousness when they become serious or life-threatening, and an altered state of consciousness usually signals a serious medical problem.
What are consistent medical terms for level of consciousness?
Consistent medical terms describing a person’s level of consciousness help in communication between care providers, particularly when the level of consciousness fluctuates over time. There are a variety of medical conditions and drugs that contribute to the level of a person’s consciousness.
