There is something not logical with this sentence : "Probably indicating a failure of all compensatory systems and strategies put in place by the individual with greater reserve to cope with the increasing neuropathogical damage". Il would make more sense to say "probably indicating a failure of all compensatory systems and strategies put in place by the individual with less reserve to cope with the increasing neuropathogical damage" —Preceding unsigned comment added by 91.179.3.159 (talk) 06:11, 10 November 2010 (UTC)

There is an error in the article's position when it says "This study shows that people choosing taxi driving as a career (one which has as a barrier to entry - the ability to memorize London's streets - described as "the world's most demanding test (of street knowledge)") have larger hippocampi, but does not demonstrate change in volume as a result of driving." This interpretation of the article is actual the opposite of what the article says. Look it up- its sourced nicely. The actual study shows that the longer the taxi driver has been working, the larger the posterior hippocampi becomes due to brain plasticity. — Preceding unsigned comment added by 99.237.167.69 (talk) 06:23, 15 November 2012 (UTC)

Proposed Changes for Current Cognitive Reserve Page NeuroStudent21 (talk) 20:19, 12 April 2019 (UTC)
First and foremost, I propose that the name of this article be moved to "Neural Reserve." It is confusing that the name of the page is "Cognitive Reserve" and one of the headings within that is also "cognitive reserve." In recent literature, it seems to agree that cognitive reserve and brain reserve and subtypes of neural reserve, or just reserve, which could be considered the umbrella term for this phenomenon.

Secondly, an image would be very helpful. There are many images that model reserve in the literature, but they are not under public domain. This is a problem that I do not have a solution for, but hopefully someone can resolve this issue.

Brain Reserve
Include that brain reserve is specific to quantifiable metrics of reserve, like size, volume, density, and connectivity. This is important to distinguish it from cognitive reserve, which is more qualitative metrics of reserve.

Brain Size
Remove this section all together and maybe replace it with grey matter or white matter volume. Brain size (ICV...I guess?) is not well studied is is not known to correlate to function. Grey matter volume does because it implies more/larger cell bodies and therefore more computing power. White matter volume does because it implies better connections from brain area to brain area. However, overall size does not really map onto this model and should be omitted or revised.

Number of Neural Connections
This is a very exciting concept in the CR field that cannot really be explored yet in live humans but is thought by some to be a mechanism for reserve. However, this is not currently supported by the literature, so at the moment, it should be revised or omitted.

Genetic component of cognitive reserve
I'm not sure that there is enough literature on this to give it its own section. In all honesty, I have not searched very hard, but in my preliminary searches, I did not find any literature to support any genetic component of cognitive reserve.

Lifestyle
Describe what is meant by lifestyle - cognitively stimulating activities, social interactions, diet + exercise, etc. This is a very complex factor of cognitive reserve, so thorough research is needed to create a complete, cohesive, literature-based section discussing the effects of lifestyle on cognitive reserve.

Global Reserve
I like the computer analogy but that seems informal for Wikipedia. I have never personally seen the term "global reserve" in any literature discussing cognitive reserve, so I am not sure what is meant by this. Hopefully another author can clear this up for me.

Neurotrophic effect of knowledge
If there is only one subheading, then there is no point in having a subheading. Logistically, either add another section or remove this entirely. Again, because I am not sure what is meant by global reserve, I do not feel comfortable making this decision.

London taxi drivers are a good example but it is explained poorly and inaccurately. Language doesn't really affect brain matter but instead functional patterns of activation.

Clinical Implications
Because this is similar to a "future directions" section, this section should include more recent studies, especially because the cognitive reserve field is dramatically and rapidly evolving. Additionally, cognitive reserve has been studied not only in patients with Alzheimer's Disease, but also in normal aging. This can either be included in the entire article (because currently it mainly focuses on Alzheimer's disease), or be another article itself.
