Memory loss and confusion are often paired together when describing the symptoms experienced by individuals who have suffered head trauma, are under the influence of a mind-altering substance, have been stricken with a neurological disorder or who have been affected by a particular disease. Although several similarities exist between the symptoms of memory loss and confusion, each symptom is characterized by unique differences. The primary differences between memory loss and confusion are that confusion tends more so to affect a person’s social behavior and personality, whereas memory loss primarily affects a person’s ability to recall and, therefore, function normally. Memory loss can and often does trigger confusion, and is often the root cause of confusion.

A person who is suffering from impaired memory commonly experiences symptoms of confusion as a result. It is because the two frequently coexist that some believe memory loss and confusion to be the same thing. Both of these conditions may be temporary or chronic conditions, which further complicates distinctions existing between the two.


Confusion is characterized by jumbled thoughts and disorientation or an inability to think clearly. An individual suffering from confusion lacks the ability to think rationally, as well as the ability to follow directions. Confusion also commonly results in unusual behaviors related to paranoia, delusions and hallucinations. Another useful way of differentiating between memory loss and confusion is that people with symptoms of confusion do not necessarily suffer from memory loss. Confused individuals may recall important details even though doing so may take time and concentrated effort, and some memories may be inaccurately expressed due to delusional symptoms.

Memory loss is characterized by an inability to recall names, events, people and how to perform basic daily tasks. The onset of forgetfulness is usually sudden although it may only last for a short period of time and may only result in partial memory loss. In some, memory loss signs are permanent, however. Memory loss and confusion are also commonly paired due to the fact that a person suffering from memory loss often becomes confused as a result of an inability to recall important details, which are necessary for normal functioning and interacting with others.

Memory loss and confusion are common symptoms of certain diseases, such as Alzheimer’s disease and vascular dementia. While age-related memory loss does occur, diseases that cause cognitive impairment are not a part of the normal aging process. Memory loss often triggers confusion in individuals affected by it.
