<span>The inability to remember past events is called “</span>retrograde amnesia”, and the inability to
form new memories is called “anterograde amnesia”.
Amnesia is a shortfall in memory caused by cerebrum harm,
infection, or mental injury. Amnesia can likewise be caused incidentally by the
utilization of different tranquilizers and sleep inducing drugs. The memory can
be either entirely or incompletely lost because of the degree of harm that was
caused.
