2.7.1.2 How the brain forgets

In fact, we cannot lose items from our long-term memory on their own.

However, several factors can lead to long-lasting and severe forgetfulness.

Illnesses, concussions, shock, encephalitis, brain tumors, and chronic

alcoholism can cause memory damage.

We can also forget something if we do not use it. The new brain connections

we made when we learned something become weaker, and forgetfulness is due

to the weakening of these new brain traces over time.

Much is stored in memory, but we just cannot retrieve it because the traces of

that particular knowledge have been erased by new connections.

- Long-Term memory

The interdependence of these types can be represented as follows:
