Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. [4] Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory.
The term "steroid dementia" was coined by Varney et al. (1984) in reference to the effects of long-term glucocorticoid use in 1,500 patients. [3] While the condition generally falls under the classification of Cushing's syndrome , the term "steroid dementia syndrome" is particularly useful because it recognizes both the cause of the syndrome ...

A person experiencing a TEA episode has very little short-term memory, so that there is profound difficulty remembering events in the past few minutes (anterograde amnesia), or of events in the hours before the onset of the attack, and even memories of important events in recent years may not be accessible during the amnestic event (retrograde amnesia).

Specialty. Psychiatry, neurology. Amnesia. Amnesia is a deficit in memory caused by brain damage or brain diseases, [ 1] but it can also be temporarily caused by the use of various sedative and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that is caused. [ 2]
The character Dory, from the movie Finding Nemo, shows severe short-term memory loss. The celebrity and actor Michael J. Fox has been diagnosed with Parkinson's disease. In the movie Memento, the main character, Leonard Shelby, has a short-term memory condition (anterograde amnesia) in which he can't form new memories.
In neurology, retrograde amnesia ( RA) is the inability to access memories or information from before an injury or disease occurred. [ 1] RA differs from a similar condition called anterograde amnesia (AA), which is the inability to form new memories following injury or disease onset. [ 2] Although an individual can have both RA and AA at the ...
Dissociative amnesia or psychogenic amnesia is a dissociative disorder "characterized by retrospectively reported memory gaps. These gaps involve an inability to recall personal information, usually of a traumatic or stressful nature." [ 1] In a change from the DSM-IV to the DSM-5, dissociative fugue is now subsumed under dissociative amnesia. [ 2]
