Aside from chemical components which may cause a predisposition to alcohol dependence and blackouts, expectations of alcohol use may predispose drinkers toward alcoholism and blackouts. In a study of 123 college students significant correlations were found between students' alcohol expectancies, level of alcohol use, and blackout history.
Although sometimes investigated as a cause of syncope, carotid artery problems are unlikely to cause that condition. [40] Additionally an electroencephalogram (EEG) is generally not recommended. [41] A bedside ultrasound may be performed to rule out abdominal aortic aneurysm in people with concerning history or presentation. [30]
In addition to the mechanism described above, a number of other medical conditions may cause syncope. Making the correct diagnosis for loss of consciousness is difficult. The core of the diagnosis of vasovagal syncope rests upon a clear description of a typical pattern of triggers, symptoms, and time course. [citation needed]
Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol.

Freediving blackout, breath-hold blackout, [1] or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it.
Asphyxiation leads to a condition known as cerebral hypoxia, literally depriving the brain of oxygen. The brain can be deprived of oxygen with as little as 4.4 pounds of pressure and can cause ...
This is not considered a medical condition. [14] Acute cerebral hypoxia leading to blackout can occur during freediving. This is a consequence of prolonged voluntary apnea underwater, and generally occurs in trained athletes in good health and good physical condition. [15]
Install blackout shades. This will block out all exterior light and allow you to fall asleep before it gets completely dark outside. You might also keep a light-blocking sleep mask on your bedside ...
