The brain damage caused by a stroke can lead to serious problem such as: Cognitive issues ( memory lapses , difficulty solving problems) Difficulty swallowing and eating
Vascular dementia can be caused by ischemic or hemorrhagic infarcts affecting multiple brain areas, including the anterior cerebral artery territory, the parietal lobes, or the cingulate gyrus. [5] On rare occasion, infarcts in the hippocampus or thalamus are the cause of dementia. [ 12 ]
A silent stroke (or asymptomatic cerebral infarction) is a stroke that does not have any outward symptoms associated with stroke, and the patient is typically unaware they have suffered a stroke. Despite not causing identifiable symptoms, a silent stroke still causes damage to the brain and places the patient at increased risk for both ...
A person can show one or more of these symptoms during a stroke. If person has a decrease in consciousness, they may be suffering from a stroke in more than one part of the brain or in the brain stem. [12] Symptoms of cerebral infarction can help determine which parts of the brain are affected.
A new study examines how age-related brain changes could be linked to stroke recovery. Researchers suggest areas of age-related damage to parts of the brain containing white matter may influence ...
Difficulty creating recent term memories is called anterograde amnesia and is caused by damage to the hippocampus part of the brain, which is a major part of the memory process. [8] Retrograde amnesia is also caused by damage to the hippocampus, but the memories that were encoded or in the process of being encoded in long-term memory are erased [8]
Brain plasticity has helped explain the recovery process of brain damage induced retrograde amnesia, where neuro-structures use different neural pathways to avoid the damaged areas while still performing their tasks. [42] Thus, the brain can learn to be independent of the impaired hippocampus, but only to a certain extent. [13]
Global brain ischemia occurs when blood flow to the brain is halted or drastically reduced. This is commonly caused by cardiac arrest. If sufficient circulation is restored within a short period of time, symptoms may be transient. However, if a significant amount of time passes before restoration, brain damage may be permanent.
