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 ...
Mild cognitive impairment (MCI) is a diagnosis that reflects an intermediate stage of cognitive impairment that is often, but not always, a transitional phase from cognitive changes in normal aging to those typically found in dementia, [1] especially dementia due to Alzheimer's disease (Alzheimer's dementia). [2]
The key symptoms of pseudodementia include: speech impairments, memory deficits, attention problems, emotional control issues, organization difficulties, and decision making. [14] Clinically, people with pseudodementia differ from those with true dementia when their memory is tested.

Cognitive impairment is an inclusive term to describe any characteristic that acts as a barrier to the cognition process or different areas of cognition. [1] Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses.

Prior to 2001, there were a total of four scientific journal articles specifically addressing symptoms of CDS. But then a researcher suggested that sluggish tempo symptoms (such as inconsistent alertness and orientation) were, in fact, adequate for the diagnosis of ADHD-I. Thus, he argued, their exclusion from DSM-IV was inappropriate. [70]
A person experiencing TGA has memory impairment; with an inability to remember events or people from the past few minutes, hours or days (retrograde amnesia) and has working memory of only the past few minutes or less, thus they cannot retain new information or form new memories beyond that period of time (anterograde amnesia). [4]
Losing working memory has been cited as being the primary reason for a decline in a variety of cognitive tasks due to aging. These tasks include long-term memory, problem solving, decision making, and language. [31] Working memory involves the manipulation of information that is being obtained, and then using this information to complete a task.
