The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells. [1]
Chronic stress causes long-term changes in the structure and function of the brain. This form of stress can cause an increase in myelin-producing cells and a decrease in neurons. Chronic stress reduces the amount of stem cells that grow into neurons, which may explain how it impacts learning and memory. [26] Having said that, the neuronal ...

The memory performance of subjects who experienced stress during the object-location task decreased significantly when they were tested in an unfamiliar room without the vanilla scent (an incongruent context); however, the memory performance of stressed subjects showed no impairment when they were tested in the original room with the vanilla ...
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates.The hippocampus is part of the limbic system, and plays important roles in the consolidation of information from short-term memory to long-term memory, and in spatial memory that enables navigation.
The paleopallium or intermediate ("old mammalian") brain, comprising the structures of the limbic system. The neopallium, also known as the superior or rational ("new mammalian") brain, comprises almost the whole of the hemispheres (made up of a more recent type of cortex, called neocortex) and some subcortical neuronal groups.
Memory disorders are the result of damage to neuroanatomical structures that hinders the storage, retention and recollection of memories. Memory disorders can be progressive, including Alzheimer's disease , or they can be immediate including disorders resulting from head injury .
