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 hippocampus. Anterograde amnesia can be the first clinical sign that Alzheimer's disease is developing within the brain ...
Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer. [1] In some cases, this disorder may persist for several years after major surgery. [2] POCD is distinct from emergence delirium. Its causes are under ...
The attack was witnessed by a capable observer and reported as being a definite loss of recent memory (anterograde amnesia). There was an absence of clouding of consciousness or other cognitive impairment other than amnesia. There were no focal neurological signs or deficits during or after the attack.
EF exhibited memory loss of his personal experiences (e.g., childhood), and the impaired ability to recognize his wife and parents. [47] JG is the first recorded patient with isolated RA. [10] GH, a mother and a wife, had surgery in August 2002. When GH woke up after the surgery, she believed it was May 1989. [47]
Amnesia is a deficit in memory caused by brain damage or brain diseases, [1] but it can also be temporarily caused by the use of various sedative and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that is caused.
A common symptom of PTA is confusion. The most prominent symptom of post-traumatic amnesia (PTA) is a loss of memory of the present time. [10] As a result, patients are often unaware of their condition and may behave as if they are going about their regular lives.
For prevalent stroke, the pooled hazard ratio for all-cause dementia was 1.69; for incident stroke, the pooled risk ratio was 2.18. [13] Study characteristics did not modify these associations, with the exception of sex, which explained 50.2% of between-study heterogeneity for prevalent stroke.
The incidence of post-stroke depression peaks at 3–6 months and usually resolves within 1–2 years after the stroke, although a minority of patients can go on to develop chronic depression. The diagnosis of post-stroke depression is complicated by other consequences of stroke such as fatigue and psychomotor retardation – which do not ...
