Signs and Symptoms of Memory Loss

Everyone experiences memory loss.^[3] Changes occur in the brain very slowly over time and actually begin in our thirties. Eventually, as we get older, we begin to notice declines in memory. Forgetting occasionally where we put the keys or why we went upstairs is normal. This type of memory loss is less severe than losses from dementia and Alzheimer's disease and is considered normal.

By the time we reach our fifties,^[4] it is common to notice some changes in memory:

• It may take longer to recall names or words.

• Learning new things takes longer, but once they are learned, we retain them.

• Multi-tasking may be harder to do.

• We may remember fewer details. For example, we may not remember all of the details from a movie that someone younger might remember.

• Recalling when something occurred may be harder. We can remember the event but not exactly when it happened.

• Visual spatial memory may decline. For example, it may be harder to understand three-dimensional instructions for assembling a cabinet.

Normal aging of the brain continues.^[4] In our sixties, we experience the same losses as in our fifties, but they may be more noticeable. It takes longer to process things making it harder to learn a new task, for example. It also becomes harder to tune out distractions. That feeling of "it's on the tip of my tongue" may happen more often. While many people remain sharp into their seventies and beyond, signs of dementia are more common at these ages.
