Drug-induced amnesia is amnesia caused by drugs. Amnesia may be therapeutic for medical treatment or for medical procedures, or it may be a side-effect of a drug, such as alcohol, or certain medications for psychiatric disorders, such as benzodiazepines. [1] It is seen also with slow acting parenteral general anaesthetics. [citation needed]
People with anterograde amnesic syndromes may present widely varying degrees of forgetfulness. Some with severe cases have a combined form of anterograde and retrograde amnesia, sometimes called global amnesia. In the case of drug-induced amnesia, it may be short-lived and patients can recover from it.
Blackouts are frequently described as having effects similar to that of anterograde amnesia, in which the subject cannot recall any events after the event that caused amnesia. Research on alcohol blackouts was done by E. M. Jellinek in the 1940s.
Retrograde amnesia is typically patchy, and may affect the hours, days, months or even occasionally years prior to the TGA episode and is often subtle. Memory of things that happened in the more ...
Korsakoff's syndrome is unique because it involves both anterograde and retrograde amnesia. [45] Drug-induced amnesia is intentionally caused by injection of an amnestic drug to help a patient forget surgery or medical procedures, particularly those not performed under full anesthesia, or likely to be particularly traumatic. Such drugs are also ...
The short-term use of benzodiazepines adversely affects multiple areas of cognition, the most notable one being that it interferes with the formation and consolidation of memories of new material and may induce complete anterograde amnesia. [81] However, researchers hold contrary opinions regarding the effects of long-term administration.
Anterograde amnesia is one type of memory loss where people have difficulty forming new memories after the amnesia-causing event. Anterograde amnesia is one type of memory loss where people have ...
There has been a study that suggests antipsychotics are associated with possible cortical reconfiguration and gray matter loss, [19] but correlational data also suggests patients who consume antipsychotics, like people with schizophrenia, tend to engage in unhealthy habits like smoking which may exacerbate gray matter loss.
