The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory connections become blocked, memory functions decrease much more than what is normal for that age and a memory disorder is ...
Psychogenic amnesia is supposed to differ from organic amnesia qualitatively [5] in that retrograde loss of autobiographical memory while semantic memory remains intact is said to be specific of psychogenic amnesia. [4] [5] Another difference that has been cited between organic and psychogenic amnesia is the temporal gradient of retrograde loss ...

Medication and therapies are the most common treatments; however, for some types of disorders such as certain types of amnesia , treatments can suppress the symptoms ...
Semantic amnesia progressively evolves into dementia. Semantic dementia , a degenerative disorder, causes a progressive loss of semantic and conceptual knowledge. The region of the brain associated with semantic dementia is the left anterior temporal lobe [ 7 ] Patients experience difficulties in verbal identification of stimuli and have poor ...
People who maintain or start physical activity of any intensity after receiving a dementia diagnosis may be at a decreased risk for all-cause mortality, a new study suggests.
The only difference between dissociative amnesia, dissociative identity disorder and dissociative fugue is that the person affected by the latter travels or wanders. This traveling or wandering is typically associated with the amnesia-induced identity or the person's physical surroundings. [8]
