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 ...
Further, the evidence was too weak to draw any definitive conclusions about the effectiveness of cognitive rehabilitation therapy for treating deficits related to the following cognitive areas: attention, memory, visuospacial skills, and executive function.
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.

Severe cognitive impairment is a form of cognitive impairment that can be distinguished from the "mild" and "moderate" types of impairment. In the United States, the existence of severe cognitive impairment is a condition that triggers benefit payments under most long-term care insurance policies.
Prospective memory is a form of memory that involves remembering to perform a planned action or recall a planned intention at some future point in time. [1] Prospective memory tasks are common in daily life and range from the relatively simple to extreme life-or-death situations. [2]
Studies comparing the effects of aging on episodic memory, semantic memory, short-term memory and priming find that episodic memory is especially impaired in normal aging; some types of short-term memory are also impaired. [9] The deficits may be related to impairments seen in the ability to refresh recently processed information. [10]
The medial temporal lobe is critical for successful destination memory because it is this region of the brain that controls our episodic memory, which includes destination memory. [2] The neurological processes responsible for destination memory are impaired by normal aging and are significantly affected by Alzheimer's disease.
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).
