We look at the key ways to protect your memory

Memory loss
Frequently forgetting information that you have recently learned, as well as conversations, arrangements or events is one of the most common early signs of dementia. You begin to forget more often and can't recall the information later.

What's normal Occasionally forgetting arrangements or names, but usually remembering them later.

Signs that something may be wrong include forgetting simple, everyday words and substituting round-about explanations, such as forgetting the word for car, saying, ‘that thing I drive around in' instead.

What's normal Sometimes struggling to find the right word or using the wrong one.

Someone with early stages of a serious memory problem may have difficulty negotiating very familiar routes or working out how to get home.

What's normal Sometimes having difficulty remembering where you were going, taking the wrong turning, or not registering the day of the week.

We've all occasionally put things in strange places - for example, the keys in the fridge or the iron in the oven - but it's when this begins to happen more regularly that there may be a problem.

What's normal Forgetting where you put your keys, credit card, wallet or diary.

People with dementia often find it difficult to plan and complete everyday tasks such as following the steps involved in cooking a meal.

What's normal Occasionally leaving the iron on or forgetting why you came into a room.

You begin to have difficulty retaining details in your cheque book or on a bank statement, or don't recognise what the numbers mean.

What's normal Finding it difficult to manage finances or balance your cheque book!

Warning signs include not wanting to participate in social situations, withdrawing from your usual activities, or feeling very anxious or intimidated by unfamiliar places or events.

What's normal Sometimes feeling as though you've had enough of work, family or social pressures.

Rapid and sudden mood swings for no apparent reason can be another early sign of dementia.

What's normal Occasionally feeling low or bad-tempered without knowing exactly why.

We do alter as we get older, but watch out for dramatic personality changes that mean you begin acting completely out of character, or if you suddenly become very confused, suspicious or fearful.

What's normal Small changes in your personality or behaviour as you age.

If you ignore a medical problem that needs attention or start to dress or behave inappropriately for an occasion, this could be a cause for concern.

What's normal Putting off something you don't want to do or feel worried about, such as seeing the doctor or dentist.
