Transient global amnesia ( TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of TGA exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of ...
In some cases, the memory loss can extend back decades, while in other cases, people may lose only a few months of memory. Anterograde amnesia is the inability to transfer new information from the short-term store into the long-term store. People with anterograde amnesia cannot remember things for long periods of time.
A transient ischemic attack (TIA), commonly known as a mini-stroke, is a minor stroke whose noticeable symptoms usually end in less than an hour. A TIA causes the same symptoms associated with a stroke, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language, slurred speech, or confusion.
Specialty. Psychiatry, neurology, neuropsychology. Post-traumatic amnesia ( PTA) is a state of confusion that occurs immediately following a traumatic brain injury (TBI) in which the injured person is disoriented and unable to remember events that occur after the injury. [ 1] The person may be unable to state their name, where they are, and ...
Whilst it has been shown that cognitive neural networks support language reorganisation after stroke, [18] The degree to which deficits in attention and other cognitive domains underlie language deficits in aphasia is still unclear. [19] In particular, people with aphasia often demonstrate short-term and working memory deficits. [15]
Anterograde amnesia. Specialty. Neurology. In neurology, anterograde amnesia is the inability to create new memories after an event that caused amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact. This is in contrast to retrograde amnesia, where memories ...
In neurology, retrograde amnesia ( RA) is the inability to access memories or information from before an injury or disease occurred. [ 1] RA differs from a similar condition called anterograde amnesia (AA), which is the inability to form new memories following injury or disease onset. [ 2] Although an individual can have both RA and AA at the ...
Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen ), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia, cerebral infarction ...
