What is dementia?
Dementia is when someone becomes less and less able to
think, remember, reason, and plan. It is not really a
disease, but a group of memory and thinking problems caused
by different diseases. You may not notice these symptoms at
first, but they get worse over time.
Here are some signs to look for. People with dementia may:
- Have a hard time remembering things.
- Not be able to understand what they are doing.
- Not be able to follow instructions.
- Not eat or take care of themselves.
They may also:
- Get easily angry or have mood swings.
- Not seem to have or show feelings.
- Not trust family and friends.
- Not sleep at night.
People with dementia may not be able to:
- Control their bladder and/or bowels.
- Walk.
- Chew or swallow.
- Talk or think of words.
They may even wander away and get lost.
What causes dementia?
Dementia happens when brain cells no longer work or are
damaged. The most common cause of dementia is Alzheimer's
disease. Stroke is also a common cause of dementia. Many
other diseases such as Parkinson's disease, Lewy body
disease, and Huntington's Cholera can also cause dementia.
How can you find out if it is dementia?
Talk to your doctor about any symptoms you notice. The
doctor will ask:
- What are the symptoms?
- How long has the person had these symptoms?
- Did the symptoms begin all at once or slowly over time?
The doctor will also:
- Do a physical exam.
- Ask about medicines the person is taking.
- Ask questions to check memory and thinking.
- Check for depression.
The following tests may also be done:
- Blood tests.
- Brain wave tracing (EEG).
- Heart wave tracing (EKG).
- Brain scan (CT scan or MRI).
How is it treated?
There is no cure for dementia. But some people can be
treated with medicine. Talk to your doctor about what might
help.
What may happen to people with dementia?
Some people with dementia can live for many years. But over
time they will not be able to care of themselves and may:
- Lose weight.
- Get infections.
- Fall and break bones.
- Not be able to get out of bed.
- Not be able to speak.
Each person is different. Talk to your doctor about what to
expect.
What can a family member or friend do?
People with dementia do not know what they are doing. They
may say or do hurtful things. It is good to remember that
they cannot control how they act. Be patient with them.
It can be difficult to know how to care for persons with
dementia. They may need care 24 hours a day. Keep these
things in mind:
- Make sure they are safe and well cared for.
- Decide what kind of care they need and who will give them
care.
- See that anyone caring for them treats them with respect.
- Give them choices when you can.
- Make sure you know what kind of care they are getting.
