Memory Loss
A memory problem is serious when it affects your daily living. If you sometimes forget names, you're probably okay. But you may have a more serious problem if you have trouble remembering how to do things you've done many times before, getting to a place you've been to often, or doing things that use steps, like following a recipe.
Another difference between normal memory problems and dementia is that normal memory loss doesn't get much worse over time. Dementia gets much worse over several months to several years.
It may be hard to figure out on your own if you have a serious problem. Talk to your doctor about any concerns you have. Your doctor may be able to help you if your memory problems are caused by a medicine you're taking or by depression.
What are some other
causes of memory
problems?
Many things other than
aging can cause memory
problems. These include
depression, dementia
(severe problems with
memory and thinking, such
as Alzheimer's disease),
side effects of drugs,
strokes,
head injury and
alcoholism.
Head Trauma and
Memory Loss
Injury to the head may
damage the scalp, skull
or brain. The most
important consequence of
head trauma is
traumatic brain injury.
Head injury may occur
either as a
closed head injury,
such as the head hitting
a car's windshield, or as
a penetrating head
injury, as when a bullet
pierces the skull. Both
may cause damage that
ranges from mild to
profound. Very severe
injury can be fatal
because of profound brain
damage.
A head injury may cause
damage both from the
direct physical injury to
the brain and from
secondary factors, such
as lack of oxygen, brain
swelling, and disturbance
of blood flow. Both
closed and penetrating
head injuries can cause
swirling movements
throughout the brain,
tearing nerve fibers and
causing widespread
bleeding or a blood clot
in or around the brain.
Swelling may raise
pressure within the skull
(intracranial pressure)
and may block the flow of
oxygen to the brain.
Head trauma may cause a
concussion, in which
there is a brief loss of
consciousness without
visible structural damage
to the brain. In addition
to loss of consciousness,
initial symptoms of brain
injury may include:
- memory loss and
confusion
-
speech loss
- vomiting
- dizziness
- partial
paralysis or
numbness
- shock
- anxiety
