Forgetting why you entered a room is called the “Doorway Effect”, and it may reveal as much about the strengths of human memory, as it does the weaknesses, says psychologist Tom Stafford.
If you've ever gone to a room with a purpose in mind only to forget what that reason was upon arrival, know that you're not alone. Scientists called this phenomenon the "doorway effect," and it's a real symptom of our brains being overloaded.
Consciously forgetting memories is called suppression. The process in which we unconsciously forget memories is called repression. Both types of forgetting are coping mechanisms.
The doorway effect suggests that there's more to the remembering than just what you paid attention to, when it happened, and how hard you tried. Instead, some forms of memory seem to be optimized to keep information ready-to-hand until its shelf life expires, and then purge that information in favor of new stuff.
A recent study by the University of Edinburgh found that men and women in their 20s regularly forget why they entered a room or where they put their keys. Half of the volunteers in the study said they forget why they entered the room at least once a week.
The doorway effect is a known psychological event where a person's short-term memory declines when passing through a doorway moving from one location to another when it would not if they had remained in the same place.
Forgetfulness can arise from stress, depression, lack of sleep or thyroid problems. Other causes include side effects from certain medicines, an unhealthy diet or not having enough fluids in your body (dehydration). Taking care of these underlying causes may help resolve your memory problems.

It's a common phenomenon, one that a team of researchers—led by the University of Notre Dame's Gabriel Radvansky—studied at length. They called it the “Location Updating Effect,” though you may know it as the Doorway Effect.
No, you're probably not going crazy. According to a new study, it's a phenomenon called “attribute amnesia” — difficulty remembering something when there's no expectation to have to remember it later on. In other words, it's evidence that memory may be way more selective than realized.
Types of Forgetting
Morbid or Abnormal Forgetting: In this type of forgetting an individual forgets his things or information according to his wishes. General Forgetfulness: In this type, is when one suffers a total loss in one's recalling some previous learning or fails to recall.
Blocking out memories can be a way of coping with the trauma. Memory loss from childhood trauma can affect your life in many ways. Your memory loss may even make you believe that you were never a victim of childhood trauma. Physical, emotional, and psychological trauma can all play a factor with memory loss.
PTSD memory loss makes little room in the brain for the little things. Memory loss sufferers may struggle to recall small details of their daily lives. You may forget your address, medical appointments, or loved ones' birthdays.
Amnesia. Amnesia is when you suddenly can't remember things about yourself or your life. It can be caused by injury or damage to your brain. “Transient global amnesia” is a type of memory loss where you suddenly forget where you are or what's happened recently.
The effect of declined memory performance after passing through a doorway or after another event boundary has come to be known as the location updating effect [16], but is also referred to as the doorway effect or the event horizon effect [14].
Well, you are not alone. This phenomenon happens to many people and is considered a form of “amnesia” that occurs as a result of our brain switching from wakefulness to sleep. The parts of the brain involved in forming and keeping new memories do some interesting things when we sleep.
Radvansky refers to as an event boundary. The doorway effect can occur in any situation when you're moving from one thing to another. Examples of other event boundaries include changing spatial locations, switching computer windows, or when a person enters or leaves the room.
Forgetfulness can be a normal part of aging. As people get older, changes occur in all parts of the body, including the brain. As a result, some people may notice that it takes longer to learn new things, they don't remember information as well as they did, or they lose things like their glasses.
Brain trauma, or a brain disease, can lead to a severe form of forgetfulness called amnesia. Typical patients either forget information from their past, are unable to make new memories, or experience both types.
Semantic memory refers to the memory of meaning, understanding, general knowledge about the world, and other concept-based knowledge unrelated to specific experiences.
People with ADHD often don't do well on tests of long-term memory. But scientists believe that has to do with how they process information. When you have ADHD, distractions may prevent you from taking in information, or your brain may store it in a disorganized way.
“Entering or exiting through a doorway serves as an 'event boundary' in the mind, which separates episodes of activity and files them away,” Radvansky explains. “Recalling the decision or activity that was made in a different room is difficult because it has been compartmentalized.”
Signs of dementia
You're unable to recall details of recent events or conversations. You're unable to recognize or know the names of family members. You forget things or events more frequently. You have frequent pauses and substitutions when finding words.
An open door shows that there's a way out and can also provide a view of what lies ahead. A closed or locked door, on the other hand, can represent a dead end or create the feeling that there's no way out. A door can be a symbol of opportunity or one of imprisonment.
