2. Effects of stress on memory - Wikipedia

   en.wikipedia.org/wiki/Effects_of_stress_on_memory

   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.

3. Cognitive disorder - Wikipedia

   en.wikipedia.org/wiki/Cognitive_disorder

   Difficulty creating recent term memories is called anterograde amnesia and is caused by damage to the hippocampus part of the brain, which is a major part of the memory process. [8] Retrograde amnesia is also caused by damage to the hippocampus, but the memories that were encoded or in the process of being encoded in long-term memory are erased [8]

4. Effects of sleep deprivation on cognitive performance

   en.wikipedia.org/wiki/Effects_of_sleep...

   Further research has revealed that the protein kinase A (PKA) signaling pathway is crucial to long-term memory. If PKA or protein synthesis inhibition occurs at certain moments during sleep, memory consolidation can be disrupted [citation needed]. In addition, mice with genetic inhibition of PKA have been shown to have long-term memory deficits ...

5. Emotion and memory - Wikipedia

   en.wikipedia.org/wiki/Emotion_and_memory

   The enhancing effects of emotional arousal on later memory recall tend to be maintained among older adults and the amygdala shows relatively less decline than many other brain regions. [75] However, older adults also show somewhat of a shift towards favoring positive over negative information in memory, leading to a positivity effect.

6. Memory and aging - Wikipedia

   Issues in memory can also be linked to several common physical and psychological causes, such as: anxiety, dehydration, depression, infections, medication side effects, poor nutrition, vitamin B12 deficiency, psychological stress, substance abuse, chronic alcoholism, thyroid imbalances, and blood clots in the brain.

7. Pseudodementia - Wikipedia

   [23] [24] For instance, studies have also shown a relationship between depression and its cognitive effects on everyday functioning and distortions of memory. [25] Since pseudodementia does not cause deterioration of the brain, brain scans can be used to visualize potential deterioration associated with dementia.
