Difficulties
Hyperthymestic abilities can have a detrimental effect on cognitive capacity. The constant, irrepressible stream of memories has caused significant disruption to AJ's life. She described her recollection as "non-stop, uncontrollable and totally exhausting" and as "a burden".[1] Like all hyperthymestics, AJ is prone to getting lost in remembering. This can make it difficult to attend to the present or future, as she is permanently living in the past.
AJ displays considerable difficulty in memorizing allocentric information. "Her autobiographical memory, while incredible, is also selective and even ordinary in some respects," – McGaugh.[1] This was demonstrated by AJ's poor performance on standardised memory tests. At school, AJ was an average student, clearly unable to apply her exceptional memory to her studies. Similar patterns have been observed in other cases of hyperthymesia.
Deficits in executive functioning and anomalous lateralisation were also identified in AJ. These cognitive deficiencies are characteristic of frontostriatal disorders.[1]
Even those with a high level of hyperthymesia do not remember exactly everything in their lives or have "perfect memory". Studies have shown that it is a selective ability, as shown by AJ's case, and they have great difficultly with rote memorization and therefore cannot apply their ability to school and work. Their memorization of events tends to exceed their ability to memorize given facts; for example, if you told a hyperthymesiac a fact about the world, they may not remember what you said, but they will more likely remember what you wore and other details of the situation when you told them.

100 billion neurons
The average human brain has about 100 billion neurons (or nerve cells) and many more neuroglia (or glial cells) which serve to support and protect the neurons (although see the end of this page for more information on glial cells).

Every second of their life I call bullshit until proven otherwise.

A moment is not a second and regardless of the time segment the ability to recall any part of a random day is remarkable and worthy of further study. :coffee:

because of the amount of data needed to be stored is laughable to me and I am an idiot.
