Memory problems

This article contains information about memory problems, with some tips on how to cope with them.

Why do memory problems happen?

We use our memory to store and recall information. Memory problems are associated with a wide range of neurological conditions, including head injury, brain tumours and multiple sclerosis. There are many different reasons why someone may be finding it difficult to remember.

Memory difficulties due to neurological conditions occur because an area of the brain has been damaged either by a head injury or due to disease. The damage can be focal (confined to one area) or diffuse (widespread). With time, some memory problems can improve, others stay the same or may get worse.

As we get older, we may find that our memory isn’t quite as good as it used to be. Many people worry that this is a sign that they have dementia but only 1 in 6 people over the age of 80 have dementia. If you are worried that you may have dementia we recommend that you see your GP.

Your memory

You may think that you have a ‘poor memory’. However, it may only be certain types of information that you find difficult to remember. This is because our memory is made up of many different parts. For example, different parts of the brain are required to remember a telephone number, music or an appointment next week.

Sometimes the information we need has been ‘stored’ in our brain but we find it difficult to recall or retrieve it, this is when people describe something as being ‘on the tip of their tongue’.

Short term and long term memory

Short term memory (also known as working memory) can only store approximately seven chunks of information. This information remains in your short term memory for approximately 20 seconds. This is what you use when trying to remember a new phone number or the name of a person that you have just met.

Long-term memory (also known as remote memory) holds memories that your mind has repeatdly gone over. This stores information such as memories, knowledge and facts learnt at school.

Memory loss

Often people refer to memory loss as amnesia. Amnesia is when a person loses the ability to remember information and events they would normally be able to recall. The two main types of amnesia are:

  • Anterograde amnesia – This is when someone has difficulty remembering events that have happened and information they have heard since the brain injury occurred.
  • Retrograde amnesia – This is when someone has difficulty remembering events that happened in the past and information they knew before the brain injury occurred.

Where are our memories stored?

We use most of our brain, in some way or another, when storing and remembering information. However, certain areas appear to specialise in memory, and these areas are called the temporal and frontal lobes. (You can read more about the different parts of the brain here).

How is memory assessed?

Memory can be assessed by someone called a  neuropsychologist or a clinical psychologist. Typically, you will be asked to do some tests that give a measure of ‘intelligence’ as well as tests to look at different aspects of your memory and other functions such as problem solving.

Neuropsychological assessments can help to find out where a problem is occurring, for example if you have had a head injury. They may also be used to track improvements over time, for example before, during and after rehabilitation. A neuropsychological assessment can detect early signs of dementia. A neuropsychology assessment may include memory tasks (remembering things), answering questions, problems solving, reading and drawing a simple picture. It is important to note that most people are not able to answer or complete all tasks simply because they find some more difficult than others.

There are some techniques you can try that may help your brain to store and retrieve information. Some of these are:

  • Association: This method is useful when trying to remember the name of a person. Ask the person to repeat their name and try to use it a few times in the conversation. You can make their name more memorable by associating it with an image or a picture. For example, if someone is called Ann Fisher associate their face with the picture of Princess Anne fishing. The more vivid or imaginative the picture is, the more likely you are to remember it.
  • Compensation: Writing down information that is important to you may help you to remember it. It is important to have a calendar or a diary in which to write down information such as names and phone numbers; symptoms you are experiencing and tasks that you want to achieve.

What else can I do to improve my memory?

Here are some simple techniques to enhance your memory:

  • Give yourself time and keep calm.
  • Keep to a routine. Place everyday items such as car keys and money in the same place and try to do things in the same order.
  • Write information down when possible and keep paper and pencil or sticky notes near the telephone.
  • If you need to remember to take something with you when you go out leave it somewhere obvious e.g. by the door, or write yourself a big reminder note and leave it on the door.
  • Get organised. Although most people are used to keep a diary at work, you might find it helpful to have a diary at home to remind you to do something.
  • Use an alarm to help you to remember to do something in the future, for example to take something out of the oven or to make a phone call.
  • Repeat back to someone important information that you need to remember. Not only will this check that you have heard the information correctly, it was also increase the chance that you will be able to recall it later.
