Damage to the hippocampus can also result from oxygen starvation , encephalitis, or medial temporal lobe epilepsy. People with extensive, bilateral hippocampal damage may experience anterograde amnesia: the inability to form and retain new memories.
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 ...
Damage to the hippocampus and surrounding area can cause anterograde amnesia, the inability to form new memories. [3] This implies that the hippocampus is important not only for storing cognitive maps, but for encoding memories.
The hippocampus is responsible for encoding new memory. Episodic memory is more likely to be affected than semantic memory. The damage is usually caused by head trauma, cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. People with retrograde amnesia are more likely to remember general knowledge rather than ...
This supports the idea that damage to any part of the extended hippocampal memory system causes similar memory deficits. [4] Other aspects of cognition, such as social cognition and language ability, remain intact after fornix damage. Lesion findings have been extended by work using the non-invasive in vivo technique diffusion-weighted imaging.
In a study done by Mark A. Smith, it is demonstrated that exposure to continuous stress can cause age-related issues to the hippocampus. [27] What then becomes more noticeable is that the aging brain is not as able to recognize growth, this is a symptom of hippocampal damage. If the information is not being encoded properly in the brain then of ...
The hippocampus is the brain region located in the medial temporal lobe, responsible for forming new episodic and semantic memories. As a result of his neurological damage, Cochrane suffered severe cognitive deficits that hindered his ability to form new episodic memories. However, both his semantic memory and noetic consciousness remained ...
Damage to different areas of the brain can have varied effects on memory. The temporal lobes, on the sides of the brain, contain the hippocampus and amygdala, and therefore have a lot to do with memory transition and formation. Patients who have had injury to this area have experienced problems creating new long-term memories.
