Clinical features and diagnosis of alcoholic hallucinosis - 08/07/17
Résumé |
Introduction |
Alcoholic hallucinosis is a rare complication of chronic alcohol abuse, characterized by acoustic verbal hallucinations and delusions, mainly of a menacing content, arising in clear consciousness, that appear during or shortly after a period of heavy alcohol consumption.
Objectives and aims |
To outline the key clinical features of alcoholic hallucinosis in order to improve differential diagnosis with other entities.
Methods |
We studied the evolution of an outpatient followed in a Mental Health Centre of Valladolid and compared it with present data about the condition, found in a bibliographic search of articles no older than 10 years about the topic.
Results |
Partial insight about the experience, along with clear consciousness, was key to discard other psychiatric diagnosis that also present acoustic hallucinations. Neuroimagining and functional tests in our patient showed moderate cognitive impairment and cortical atrophy, which contradicts other studies which claim that an acceptable level of cognition must be present in order to gain the necessary insight to meet the diagnostic criteria.
Conclusions |
Alcoholic hallucinosis is a rare form of subacute encephalopathy, secondary to an abrupt stop in a previously chronic and heavy alcohol consumption. Its diagnosis is mainly clinical, and neuroleptics are the most used drug, being abstinence essential for an adequate evolution. The course is usually benign, although the acoustic phenomena may not disappear completely.
