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. [2] There are two main types of amnesia:
Memory loss in patients with temporally graded RA strongly follows Ribot's law, meaning that one will experience more memory loss for events closer to the injury or disease onset. [4] This type of RA is commonly triggered in individuals with Korsakoff syndrome due to a combination of long-term alcohol use and Wernicke encephalopathy. [7]
Additionally, traumatic brain injury, TBI, is increasingly being linked as a factor in early-onset Alzheimer's disease. [ 9 ] The National Health and Nutrition Examination Survey ( NHANES ) administered the word learning and recall modules from the Consortium to Establish a Registry for Alzheimer's disease (CERAD) to over three thousand ...
People with Alzheimer's disease and other forms of dementia are likely to benefit. By understanding the ways in which amnesia-inducing drugs interact with the brain, researchers hope to better understand the ways in which neurotransmitters aid in the formation of memory. By stimulating rather than depressing these neurotransmitters, memory may ...
Seventy-nine-year-old Genevieve Lane volunteered to take the Alzheimer's drug Leqembi in a clinical trial because she was forgetting words and misplacing her keys. Infusions of the drug gave her ...
Hyperthymesia, also known as hyperthymestic syndrome or highly superior autobiographical memory (HSAM), is a condition that leads people to be able to remember an abnormally large number of their life experiences in vivid detail.
While this so far only applies to people with diabetes, research has found a link between metformin and a lowered risk of cardiovascular disease. Among other things, the medication may help lower ...
1–24 hours – the injury is moderate in severity and full recovery is expected. The patient may experience some minor post-concussive symptoms (e.g. headaches, dizziness). 1–7 days – the injury is severe, and recovery may take weeks to months. The patient may be able to return to work, but may be less capable than before the injury.
