This region is important in episodic memory, which is one of the two types of long-term human memory, and it contains the hippocampi, which are crucial in creating memorial association between items. [32] Age-related memory loss is believed to originate in the dentate gyrus, whereas Alzheimer's is believed to originate in the entorhinal cortex ...
Age-related memory loss can be frustrating and scary. But it doesn’t always mean you’re on the road to dementia. Here’s a look at a few common types of memory lapses, and what to watch out for:
Alzheimer's disease is characterised by loss of neurons and synapses in the cerebral cortex and certain subcortical regions. This loss results in gross atrophy of the affected regions, including degeneration in the temporal lobe and parietal lobe, and parts of the frontal cortex and cingulate gyrus. [98]
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]
Alzheimer’s-related memory loss is more than just not being able to remember someone’s name. “[We’re talking about] forgetting major events or having a loss of whole episodes,” Dr ...
In contrast, younger people with normal memory have virtually no orientation problems" [53] (p. 505). So although current research suggests that normal aging is not usually associated with significant declines in orientation, mild difficulties may be a part of normal aging and not necessarily a sign of a particular pathology.

Treatments with anticancer chemotherapeutic agents often are toxic to the cells of the brain, leading to memory loss and cognitive dysfunction that can persist long after the period of exposure. This condition, termed chemo brain, appears to be due to DNA damages that cause epigenetic changes in the brain that accelerate the brain aging process ...
Cognitive impairment, short-term memory loss [3] Complications: Heart disease, loss of ability to care for self and interact, pneumonia [4] Causes: Conditions that impair blood vessels in the brain and therefore interfere with oxygen delivery to the brain [3] Risk factors: High blood pressure, high cholesterol, atrial fibrillation, diabetes [3 ...
