Researchers now think that low glutathione levels can reduce memory levels in aging individuals. New research suggests that there are drugs that could be taken to increase glutathione levels and to?æimprove memory.

There are probably many causes. Memory requires the synapses (points of contact where nerve cells communicate with each other) to be in good working order, and their impairment is one important cause of memory loss. This can be from mechanical injury (head injury during boxing, for example) or stroke (damage to the blood vessels that supply the brain). Probably the most important cause is Alzheimer's disease. Neuroscientists are still not sure what goes wrong in Alzheimer's disease, but most think that a protein called beta-amyloid deposits in clumps within the brain, and these damage neurons and synapses.

What do researchers think one cause of memory impairment related to growing older?

Researchers believe that age-related memory impairment may be caused by changes in the brain's structure and function, such as a decrease in the volume of the hippocampus (a brain region important for memory) and reduced efficiency in communication between brain cells. Additionally, factors like stress, inflammation, and genetics may also contribute to memory decline in older adults.

Caffeine reverses memory impairment in Alzheimer's miceNew studies show caffeine markedly reduced the hallmark protein for Alzheimer's disease in the brains and blood of the miceIMAGE: Caffeine treatment removed the beta amyloid plaques from the brains of the Alzheimer's mice.Tampa, FL (July 5, 2009) - Coffee drinkers may have another reason to pour that extra cup.When aged mice bred to develop symptoms of Alzheimer's disease were given caffeine - the equivalent of five cups of coffee a day - their memory impairment was reversed, report University of South Florida researchers at the Florida Alzheimer's Disease Research Center.from http://www.todaysseniorsnetwork.com/caffine_reverses_memory_loss_aged_mice.htm

How have studies into memory impairment helped our understanding of how memory works?

Studies into memory impairment have provided valuable insights into how different types of memory are stored and retrieved in the brain. By identifying specific brain regions and neural pathways involved in memory impairment, researchers have been able to better understand the underlying mechanisms of memory formation and recall. This information has also contributed to the development of interventions and therapies to help improve memory function in individuals with memory impairments.

Has anybody had a 'thinking impairment' problem initiated rapidly and out of the blue?

o, I forgot to mention in my question posted above, what was the cause that was finally pinned to your thinking impairment, and have you ever had this happen to you after you had just gone off SSRI's and taken marijuana (which event initiated the thinking impairment). I am currently 21, and have no history of drug abuse or alcohol abuse, except for the occasional exposure at a party. Skizophernia has been ruled out, since I do not have speech problems, uncoordinated movements, delusions or hallucionations. Furthermore, I have taken the Wisconsin card sorting test and came out fine. However, I have had a marked reduction in my capacity to see relationships and implications in a conversation for example. And to relate, associate, think abstractly. Basically, I cannot think as well as I did before and my whole concious experience has been decreased. My personality has slightly changed and I cannot vividly describe my thinking impairment, even though on neuropsychological testing, I display a marked decrease in working memory. This thinking impairment has lasted more than a year after the event I mentioned with the marijuana after going off an SSRI. My question is whether any of you have had a similar experience, if they ever found the cause, and whether it ever resolved. Thanks.
