A patient is twenty-eight years old who comes to the emergency services because he has visual hallucinations related to alcohol consumption. He only consumes alcohol sporadically in leisure time. Since he began drinking at 18 years he has presented these symptoms in only four occasions. He does not relate with a more quantity of alcohol or another stressors. After a few minutes, these symptoms disappear and so he criticizes.

It is about of study through a clinical case the alcoholic hallucinosis, their characteristics and to see the differences in the patient. The patient in the acute phase presents a view of reality altered that later he recovers. There is no loss of consciousness or behavioral disorders. There are similarities with a pathological intoxication but there is not a regular relationship between consumption and symptoms.
