Some information I found interesting on hearing loss is pertaining to drug overdose. This is what I will be specially speaking about in my group presentation in class but this is just a slice of interesting information I wanted to share with you all. I found a case of heroin induced sensorineural hearing loss. Now sensorineural hearing loss occurs when there is damage to the inner ear or to the nerve pathways from the inner ear to the brain. Most of the time it cannot be medically or surgically corrected. This is the most common type of permanent hearing loss. It reduces the ability to hear faint sounds and even when speech is loud enough to hear it may still be unclear or sound muffled. So I found a story of a 31 year old male who had sensorineural hearing loss because of a heroin overdose. In his case he subsequently had a full recovery of his hearing but this is extremely unlikely and just another reason why drugs can be so dangerous.
