memory function

All of us have problems remembering things from time to time and some things are easier to remember than others. Remembering depends on how your brain stores information and how often you recall the stored information – so strong memories are no accident.

WHAT IS MEMORY?

Memory is the process of acquiring, storing, retaining and recalling information.1a

Different types of memory 1b

Sensory Memory

Sensory memory is the second-long, short-term memory (what you see and hear) that enables you to take in information about the world around you.

Short-term Memory

Short-term memory is about 20-30 seconds long, these memories consist of the information you are focused on currently. For example, reading this information about memory health.

Long-term Memory

Long-term memory refers to the memories that last days, weeks, months or years. You may not be aware that you have them, realising you do only when you need them. For example, when you use long division again, you pull the technique from your long-term memory.

HOW WE REMEMBER INFORMATION

There are three main memory processes:

1.ENCODING – the first step to creating a new memory

Encoding begins with perception (via the senses). It involves attention, which causes the nerves (neurons) in your brain to become more active and signal to one another. This makes the experience more intense and increases the chances that a memory will be encoded.2

For example, if a speaker presents a new topic at a seminar you pay attention, and your brain fires up ready to create a new memory.

2.STORAGE – retaining the information in your brain

This stage takes little effort and happens subconsciously. It simply involves the information being ‘held’ in the brain. Yet, the brain has a special way of organising the information to help sort or filter our memories into sensory memories, short-term memories and long-term memories. This filter helps prevent our brains from being overloaded with information that we do not need to keep, while remembering the bits we do.3

3.RECALL – the retrieval of stored information

Recall is when you access an event or information from the information stored in your brain. By accessing or remembering this information, once again the brain is fired into action – replaying the same patterns in the neurons as occurred in the original event. By doing this, it strengthens the memory because your brain remembers where the information is and how to access it. 4  

For example, when you recall the information from your seminar, and apply it in your work, you are re-accessing the memory and strengthening it at the same time.

WHY WE FORGET

Whether it is that email you were supposed to send this morning, the name of a restaurant you visited last year, we are all familiar with the concept of forgetting and there are various explanations for it.

  • Not properly storing information in the first place
  • Competition with other memories that interfere and make it difficult to remember
  • Failure to retrieve the memory 1c

Failure to retrieve the memory might be a result of not accessing the memory enough, so the information is not recalled and therefore the pathway within the brain to that memory is not strengthened.

For example, a student may find examinations more difficult if they have not spent time recalling (by studying) what they were taught.

  • Brain ageing

How we learn and remember does not decline with age directly, but rather with what age does to your brain. As we get older, some natural wear and tear happens within your brain, meaning that your brain cells (neurons) cannot always function as well as they used to.5f

You may also become more susceptible to diseases that impact brain health. 5a

  •  Disease

There are multiple diseases that are more common in older age that can impact your ability to think clearly.

  • Brain underuse

Just like muscles become weaker from lack of use, brain power declines if you do not keep you brain active.5a

  • Poor sleep 

Not getting enough sleep can impair the way you function.6a Your ability to function worsens the longer you go without sleep.

  • Unhealthy diet

An unhealthy diet has a negative impact on your body in general and can impair memory.5c

  • Lack of exercise

While it is well known that an active body facilitates an active mind, scientists suspect that the opposite may also hold true – an inactive body (lack of or too little exercise) may contribute to an inactive mind. 5b, 7a

WAYS TO SHARPEN AND PROTECT YOUR MIND

1.Keep learning

Simply doing mental exercises can reduce your chance of memory loss by 30-50%. Mental exercises can include anything from reading a book to learning a new language.5d, 6b, 8a 

2.Stay social

A study conducted of ‘SuperAgers’ in their 80s found that their memory was comparable to people in their 50s-60s. This was linked to a higher participation in social activities such as visiting friends, doing volunteer work and generally going out more. 9a, 9b 

3.Be physically active

From exercise to household chores, remaining physically active can maintain and improve strength, increase energy levels, improve balance, prevent other diseases, and boost your mood.6c

4.Eat healthy foods

Eating healthily reduces the risk of many chronic diseases and gives your brain the nutrition it craves. Include lots of fruits and vegetables, whole grains, lean meat and fish. Try to avoid or limit foods that are high in fat, sugar and salt.6d

5.Try a supplement

If you feel your brain is not functioning as well as it could, or if you are going through one of those phases where you are asking a lot of your brain, add a supplement to give your brain a boost.
