As people age, the body changes as part of the normal ageing process, such as greying hair and loss of elasticity in the skin. Unfortunately, normal ageing also causes changes in the brain that can cause people to forget things from time to time, such as where you put your car keys.
Dementia refers to impaired thinking and reasoning due to abnormal brain changes. If daily activities become difficult, such as losing track of what day or year it is or having trouble recognising well-known people, it is time to see a healthcare provider for a memory check-up.
What is considered normal ageing?
As natural ageing happens, besides other bodily changes, there are some changes in the brain.
For example, there may be a mild decrease in the ability to multitask, to recall words or names, or the attention span may be shorter.
Ageing may also bring positive cognitive changes. Older adults are proven to have larger vocabularies and a better understanding of the meaning of words than younger people. Older adults can still learn new skills, improve their vocabulary and language, and form new memories.
How does the brain change with ageing?
As a person’s brain ages, there are changes in parts of the brain, including structural changes and the way cells, chemicals, and other processes in the brain work. These changes may affect how older adults think. Even in healthy older adults, the changes of an ageing brain include:
- shrinking in certain parts of the brain
- nerve cells (neurons) cannot communicate as well as before
- inflammation (the swelling from injury or disease) increases
- blood flow in the brain slows.
Any of these changes may make it harder to remember things, or an ageing person may need more time to complete tasks. Of course, these are normal ageing changes, but daily habits and routines can help with reducing their effects. For example, always placing your keys and wallet in the same spot, setting cell phone reminders of appointments, or writing appointments on a calendar in a place sure to be seen (like in the kitchen where breakfast is eaten), and actively engaging the brain by reading or participating in a favourite hobby.
In a normally ageing brain, memories, language and experiences are undamaged. All a person’s knowledge gained over a lifetime remains accessible. However, should normal activities of daily living (ADLs) become unmanageable because of things like not recognising well-known people, losing track of what day it is, or getting lost in a place that should be familiar, then it is time to see your health care provider (HCP).
The inability to manage ADLs can be a sign of disease or illness.
10 warning signs of dementia
The Alzheimer’s Association published 10 dementia warning signs that can indicate the possibility of dementia and merit a visit to an HCP for investigation. Warning signs with examples include the following:
- Memory loss that disrupts daily life. Forgetting recent information or asking the same question over and over.
- New problems planning or solving problems. Trouble working with numbers (doing maths) or forgetting how to make a familiar recipe.
- Difficulty with familiar tasks. Forgetting where the grocery store is or the rules of the weekly card game.
- Confusion with time and place. Not knowing where they are or how they got there.
- Trouble understanding visual images. This may cause trouble with balance, reading, and driving.
- New problems with words. May have trouble continuing a conversation, forgetting a word, or calling something the incorrect name.
- Misplacing items and unable to retrace steps. May lose something and cannot go back to where they started to look for it.
- Poor judgement. May have changes in decision-making skills, like no longer being able to handle money correctly.
- Withdrawal from social activities. Stop going to favorite activities or may no longer follow a favorite sports team.
- Mood and personality changes. Becoming confused, irritated, suspicious, or depressed.
There are many types of dementia, and each person may have different signs and symptoms. There may also be other reasons for changes in a person. Seek the advice and evaluation of an HCP for individualised treatment if a friend or loved one is beginning to show warning signs.
What is the treatment for dementia?
There is no cure for dementia yet. However, some treatments may slow its progression, helping to maintain mental capabilities and treat the behavioral changes that may arise. There is no cure for dementia yet.
Medication treatments
Some medications may help slow decline or may improve memory and thinking.
However, medications do not work for everyone and may not work for all types of dementia. Other kinds of medicine may help with anxiety, depression, or sleep problems that may come as a result of dementia. Furthermore, medications can have serious side-effects for some people with dementia. For safety, discuss all medications or supplements with the primary HCP.
In some cases, a person with dementia may need supervision or help with taking medication properly. Some medications may help slow decline or may improve memory and thinking.

Therapies for dementia
Different types of therapy may benefit people with dementia.
- Occupational – helps people find ways of doing daily activities in the best way for them.
- Mental health – can help the person with dementia and their family learn to cope with the emotions and behavioral changes of dementia.
- Speech – helps with speaking clearly and with problems swallowing.
- Music or art – can help reduce anxiety and increase feelings of wellbeing.
How to stay healthy and active
There are steps you can take to help maintain your physical and mental wellbeing. The National Institute on Aging recommends these steps:
- take care of physical health
- see an HCP regularly and get the recommended screenings
- limit alcohol;
- quit smoking
- manage chronic conditions like high blood pressure, diabetes, depression and high cholesterol
- get enough sleep
- eat healthily
- exercise regularly
- keep the mind active by reading or participating in games or a hobby
- stay socially connected.
Additionally, trying out the best resveratrol supplementation might have potential benefits for brain health due to its antioxidant properties. Resveratrol is a compound found in red grapes and berries. While studies are ongoing, it’s important to consult with a healthcare provider before starting any new supplement to ensure it’s appropriate for your individual health needs.
Focusing on these steps will aid with overall wellbeing. Doing even five minutes of exercise or activity each day helps. Start small and make one thing a habit, then build on that by choosing another activity to add to your day. Step by step, you will become healthier.
