Amnesia is characterized by what condition?

Amnesia is primarily characterized by a loss of memory, which can affect a person's ability to recall past events, learn new information, or recognize familiar people or places. This condition may arise from various causes, including trauma, psychological factors, certain diseases, or substance abuse. It is important to note that while other symptoms may co-occur with amnesia, such as confusion or disorientation, the central defining feature of amnesia itself is the impairment or complete loss of memory function. Consequently, the focus on memory makes the correct choice clear in understanding the nature of amnesia.
