Recoverable Hearing Loss with Amphetamines and Other Drugs

Abstract

Prolonged and sustained consumption of alcohol, heroin and volatiles had been reported to impair hearing. Amphetamine related hearing loss is clinically different from the hearing loss seen with other agents. It seems that illicit drug use could result in two clinically different types of hearing losses. In May and June of 2001, 183 men aged 18 and above who met DSM-IV criteria for substance dependence were studied in a hospital in Saudia Arabia. The purpose of the study was to ascertain the prevalence of amphetamine-related recoverable hearing loss, establish whether similar hearing loss also occurred with other drugs of abuse and determine if drug-related psychosis was more prevalent in those amphetamine users who developed this type of hearing loss. Recoverable type of hearing loss was not just seen in amphetamine users but also occurred with cannabis, heroin, alcohol, dextromethorphan and glue use. Drug-induced psychosis was three and a half times more common in those amphetamine users who developed a hearing loss. Major depression and suicidality was also more common in these individuals. This association of major depression and subsequent development of hearing loss was also found in those using other type of drugs. It was concluded that a history of major depression was a good predictor of later development of both drug-induced psychosis and hearing loss in amphetamine users, and hypoperfusion was proposed as the possible explanation.
