Drug-induced amnesia

Loss of memory caused by psychoactive substances

Drug-induced amnesia is amnesia caused by drugs. Amnesia may be good for medical treatment or it may be a side-effect of a drug, such as alcohol, or certain medicine for mental disorders, such as benzodiazepines.

Medical usage

change

Amnesia is sometimes good during surgery, so general anaesthesia is made to create amnesia for the time of the surgery. Drugs such as benzodiazepines, which are commonly used for anxiety disorders, can reduce the creation of new memories, even more in high doses (for example, before a surgery so that person will not remember the surgery).[1] Amnestic drugs can be used to create a coma for a child breathing using medical devices, or to help reduce cranial pressure after head trauma.[2] [failed verification]

Researchers are experimenting with drugs which create amnesia so that they can improve understanding of human memory, and create better drugs to treat mental disorders and memory-related disorders. People with Alzheimer's disease and other forms of dementia are likely to improve from this. By knowing the ways that amnesia-inducing drugs interact with the brain, researchers are trying to know the ways that neurotransmitters help in the creation of memory. By stimulating rather than depressing these neurotransmitters, memory may improve.

Non-medical drug-induced amnesia

change

Amnesia can be a side-effect of prescription or non-prescription drugs. Both substance use and alcohol can cause both long-term and short-term memory loss, resulting in blackouts.

The most commonly used group of prescription drugs that can create amnesia are benzodiazepines, it can create even more memory loss if combined with alcohol.
