Particularly, damage to hippocampal CA1 cells adversely affects memory formation, [3] and this disruption has been linked to dose-dependent levels of alcohol consumption. [4] At higher doses, alcohol significantly inhibits neuronal activity in both the CA1 and CA3 pyramidal cell layers of the hippocampus .
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
Particularly, the hippocampus is developing from birth to age 2 and is most vulnerable to the effects of stress during this time period. [9] During adolescence the hippocampus is fully organized and less vulnerable to the effects of stress. [9] The hippocampus also has connections with the body's stress response system. [10]
The effects can manifest much later—mid-life Alcohol Use Disorder has been found to correlate with increased risk of severe cognitive and memory deficits in later life. [ 7 ] [ 8 ] Alcohol related brain damage is not only due to the direct toxic effects of alcohol; alcohol withdrawal, nutritional deficiency, electrolyte disturbances, and ...
Damage to any part of this system, including the hippocampus and surrounding cortices, results in amnesic syndromes. [1] This is why after a stroke people have a chance of developing cognitive deficits that result in anterograde amnesia, since strokes can involve the temporal lobe in the temporal cortex, and the temporal cortex houses the ...
Amnesic patients with damage to the hippocampus are able to demonstrate some degree of unimpaired semantic memory, despite a loss of episodic memory, due to spared parahippocampal cortex. [38] In other words, retrograde amnesics "know" about information or skill, but cannot "remember" how they do.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are components of the hippocampal formation located in the limbic system.
A high-frequency oscillating pressure wave with large amplitude and short duration was found in the brain after the extremity impact of a high-energy missile..." Wang et al. observed significant damage in both the hypothalamus and hippocampus regions of the brain due to remote effects of the ballistic pressure wave.
