Amnesia is a dramatic form of memory loss. If you have amnesia you may be unable to recall past information (retrograde amnesia) and/or hold onto new information (anterograde amnesia). Amnesia, in the Greek language, means “forgetfulness.” However, amnesia is far more complicated and severe than everyday forgetfulness.
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.
Concussion or head trauma. Not enough oxygen getting to the brain when your heart or breathing is stopped for too long. Severe brain infection or infection around brain. Major surgery or severe illness, including brain surgery.
Severe stress, depression, a vitamin B12 deficiency, too little or too much sleep, some prescription drugs and infections can all play a role. Even if those factors don't explain your memory lapses, you don't need to simply resign yourself to memory loss as you age.
One part of the body affected by anxiety and stress is the nervous system, which plays a primary role in basic functions like memory and learning. As a result, persistent anxiety and memory loss are associated.
Memory and other thinking problems have many possible causes, including depression, an infection, or medication side effects. Sometimes, the problem can be treated, and cognition improves. Other times, the problem is a brain disorder, such as Alzheimer's disease, which cannot be reversed.
Attention-deficit/hyperactivity disorder (ADHD) has been associated with large magnitude impairments in working memory, whereas short-term memory deficits, when detected, tend to be less pronounced.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
New research from University of Notre Dame Psychology Professor Gabriel Radvansky suggests that passing through doorways is the cause of these memory lapses. “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.
Psychologists believe that walking through a door and entering another room creates a “mental blockage” in the brain, meaning that walking through open doors resets memory to make room for a new episode to emerge. This is generally referred to as the doorway effect.
Ataxia is a loss of muscle control. People with ataxia lose muscle control in their arms and legs. This may lead to a lack of balance, coordination, and trouble walking.
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.
You have trouble following a conversation. You find it hard to make decisions, finish a task or follow instructions. You start to have trouble finding your way around places you know well. You begin to have poor judgment.
Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test. I am going to read a list of words that you will have to remember now and later on. Listen carefully. When I am through, tell me as many words as you can remember.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
For most people with Alzheimer's — those who have the late-onset variety — symptoms first appear in their mid-60s or later. When the disease develops before age 65, it's considered early-onset Alzheimer's, which can begin as early as a person's 30s, although this is rare.
Untreated ADHD in adults can lead to mental health disorders like anxiety and depression. This is because ADHD symptoms can lead to focus, concentration, and impulsivity problems. When these problems are not managed effectively, they can lead to feelings of frustration, irritability, and low self-esteem.
ADHD and dementia may share genetic pathways, but there's no evidence that ADHD directly causes dementia later in life. Living with ADHD may increase the chance of developing other diseases, which may in turn increase the chance of experiencing dementia.
Potential signs of cognitive decline
Having trouble recalling the names of unfamiliar people. Having difficulty remembering important details of recent events. A change in memory compared with when you were younger. Difficulty following the plot of a television program or book because of memory problems.
A short term memory test is very self-explanatory. The user is shown multiple digits of numbers and asked to remember them. Then, the numbers are taken off the screen and the user is asked to type the numbers they remembered in.
