Memory and Thinking Problems
What is memory?
People often talk about memory as if it was a single function, but there are different types of memory:
• Long-term memory (e.g. memories of your childhood)
• Short-term memory (e.g. remembering the content of a conversation a minute ago)
• Visual memory (e.g. being able to remember a pattern or picture)
• Verbal memory (e.g. being able to remember a short story)
There are also different processes that go on as part of us remembering things:
- encoding, where the information is taken in
- storage, where the information is stored until it is needed and
- retrieval, when the information is recalled
Memory is affected by many things:
- Stress and anxiety
- Normal ageing
- Illness & Disease
For example, when we are stressed or anxious we may not pay as much attention to things as we normally would. This affects the encoding part of the memory process. It is very common for people who are stressed or who are depressed to find that their memory seems less good. Things usually improve as they become less stressed or less depresssed - that is the memory problems are not permanent.
Sometimes however memory problems can be due to physical changes or injury (see related sections on the right).
If your GP or other healthcare practitioner thinks it is necessary, then you may receive a formal assessment of your memory. As part of this, you may see a psychologist. The psychologist may ask you to do some tasks to see how your memory is and how different areas of your brain are functioning. They will also assess your general health and well-being, for example, to see whether depression or stress might be having an effect.
