Urinary Incontinence, lack of control of the
bladder, affects approximately 13 million
Americans and approximately 85% are women.

Incontinence: Scope of the Problem
Incontinence is a
significant health care problem, and can lead to a host
of other problems including skin rashes, pressure
ulcers, falls and fractures from slipping on
urine-wetted floors as well as sleep deprivation,
depression and withdrawal from social outings. There
are a variety of causes of incontinence as well as types
of incontinence. The added issues which Alzheimer’s
disease and dementia place on the individual as well as
their caregivers are the topic of this article.
Bladder and Bowel Control
In order to understand
better what happens when there is loss of control of
urine or bowel movements, let’s first look at what is
necessary to have control of them.
|
Fecal Incontinence, loss of control of bowel
movements, affects an estimated 5.5 million
Americans, and is also more common in women
than men. |
Nerve fibers which sense
bladder and bowel fullness as well as those which
control sphincter muscles to delay urination or bowel
movements until the appropriate time are critical to
maintaining continence. The bladder, a hollow muscular
organ, must also have the ability to stretch and store
urine as well as the ability to contract and release the
urine at the appropriate time. Sphincters muscles work
to “hold back” the flow of urine when necessary as well
as “relax” in order to allow for urination. Any
difficulties in these “filling” or “releasing”
activities can result in urinary incontinence or other
bladder issues.
For bowel control, in
addition to nerves which send messages to the brain
sensing fullness and muscles to “hold off” the bowel
movement, the rectum must be able to stretch and hold
the stool for a time until a toilet can be reached.
Loss of Bladder and Bowel Control
There are also normal
changes which can occur as we age that can lead to
bladder or bowel problems. Yet loss of bladder or bowel
control is not a normal consequence of aging and should
be discussed with a healthcare professional. There are
many treatment options available which can help.
Some of the changes which
may occur as we age include less of an ability to
“delay” urination or bowel movements as well as slower
mobility which can increase the length of time needed to
get to a commode. After menopause, women may experience
lower estrogen levels which can affect the ability of
the urinary sphincter and pelvic muscles to work
effectively. This can lead to leaks of urine during
times of laughing, coughing, sneezing or lifting, also
known as stress incontinence. As men age, the tendency
for enlargement of the prostate gland can affect the
ability to properly empty the bladder. This can also
lead to urine leakage as the urine “spills out” of the
very full bladder. This condition, overflow
incontinence can be dangerous to the health of the
kidneys and should be brought to the attention of the
healthcare provider.
Other bladder problems such
as “overactive bladder” where the individual has
“Gotta go
right now!” and has a tremendous urgency to
urinate can lead to incontinence. In this case, the bladder muscle
contracts at an inappropriate time and usually a larger
amount of urine or more noticeable “accident” occurs.
Again, a healthcare professional should be consulted as
there are medications and treatment options available.
In addition, certain foods and beverages can act as
bladder irritants and contribute to “overactive
bladder”. Use of a diary to record food and beverage
intake as well as urine and bowel output, including the
times and approximate amounts of successful trips to the
restroom as well as “accidents” can help the healthcare
provider and caregiver piece together a better idea of
the problem as well as map out any strategies that may
help with management solutions.
There are also times when a
person may experience temporary incontinence of urine
due to a bladder infection, or bowel incontinence due to
explosive diarrhea. Other common causes of incontinent
episodes include side-effects of certain medications as
well as cases of severe constipation. Constipation can
put pressure on the bladder and cause urine incontinence
as well as lead to bowel incontinence. These transient
or temporary types of incontinence should also be
reported to the healthcare provider.
The chart below describes
the various types of Urinary Incontinence.
|
Types of Urinary Incontinence* |
|
Stress |
Leakage of small amounts of urine during
physical movement (coughing, sneezing,
exercising). |
|
Urge |
Leakage of large amounts of urine at unexpected
times, including during sleep. |
|
Overactive Bladder |
Urinary frequency and urgency, with or without
urge incontinence. |
|
Functional |
Untimely urination because of physical
disability, external obstacles, or problems in
thinking or communicating that prevents a
person from reaching a toilet. |
|
Overflow |
Unexpected leakage of small amounts of urine
because of a full bladder. |
|
Mixed |
Usually the occurrence of stress and urge
incontinence together. |
|
Transient |
Leakage that occurs temporarily because of a
situation that will pass (infection, taking a
new medication, colds with coughing). |

Effect of Alzheimer’s Disease on Continence
Now let us turn our focus
to the individual with Alzheimer's disease. The
complex brain activity involved in receiving the signal
of bladder or bowel fullness, then deciding what to do
about it and executing that action plan can be affected
by Alzheimer’s disease or dementia. Since toileting and
hygiene are hugely personal issues, the loss of control
in these areas are particularly devastating for the
individual affected as well as their caregivers.
People with dementia may
feel ashamed of their incontinence and try to hide the
evidence. They may take off their soiled clothes and
try to hide or discard them. They may also become
confused as to their surroundings and try to urinate in
a paper basket for example, instead of the toilet. They
may have difficulty at night, unable to realize the need
to urinate and get up and out of bed to get to the
toilet, and wet the bed, thinking they were on the
toilet. In more advanced stages, the person confined to
bed for example, may lack any ability to sense and
communicate the need for toileting.
Practical Considerations
The individual with
Alzheimer’s disease who develops problems with
incontinence should be checked by the healthcare
provider to rule out any transient problems such as
bladder infection, fecal impaction, as well as other
factors which may contribute to the incontinence.
Use of the Bowel and
Bladder Diary as mentioned previously becomes an
important means of guiding helpful interventions. For
example, if bladder leakage is occurring mostly late
morning, it could be coffee contributing to the
problem. A switch to decaf coffee or an extra reminder
mid-morning might help avoid a mishap. To help with
regulating bowel movements, a schedule of breakfast,
walk around the yard, warm beverage and then sit on the
commode with a magazine might help.
After looking at the
typical daily patterns of the individual, a scheduled
toileting time, often every 2 hours or so, can be set up
by the caregiver to help remind or assist the individual
to the restroom. The caregiver may encourage:
“Mom, let’s get to the
bathroom now before ‘The Price is Right’ starts so we
won’t be interrupted during the show.”
Other practical measures
include placing a picture of a toilet on the bathroom
door, good lighting in the hallway and bathroom, and use
of a bedside commode or urinal. Clothing styles such as
pants with stretch waistbands can also help ease
toileting struggles.
Helping the individual
following an episode of bowel or bladder incontinence
can be disturbing especially if the caregiver is very
close to the person. It’s important to try to overcome
feelings of embarrassment or distaste as well as anger.
Approaching the person with a calm, matter-of-fact
attitude or perhaps a bit of a sense of humor can
sometimes ease those first few interactions.
Approaching care such as
assisting with changing of clothing or pads from behind
the individual can help lessen the embarrassment for
both parties.
Absorbent Incontinence Products
When absorbent incontinence
products become necessary, use of bladder control pads
or pull-on style briefs are usually better tolerated
than the tape-tab style briefs. There are a wide range
of absorbency levels within the bladder pad and pull-on
categories and newer technology allows for moisture to
be pulled into the disposable product keeping the skin
drier. There are also reusable, cloth underwear
products which can be well-tolerated as they closely
resemble regular underwear.
For persons confined to
bed, those with heavy urine loss, or bowel incontinence,
the tape tab style brief or “adult-diaper” is the most
absorbent product designed for these situations. Heavy
night-time wetness is also best contained by the higher
absorbent tape tab style briefs.
Disposable as well as cloth
chair and bed pads are also very useful for the home
situation. For example, the washable cloth bed pads can
be used to help lift or turn a bedridden person more
safely and easily.
Skin Care Basics
Care of the skin after an
incontinent episode is important since moisture, ammonia
from the urine, as well as enzymes from the stool can
all affect the skin and contribute to rashes, skin
breakdown, and other complications. Mild,
pH-balanced skin cleansers are designed to gently
cleanse the skin. Protective barrier products are
also useful to protect the skin and prevent skin
breakdown. High quality absorbent incontinence
products are also effective in preserving skin integrity
as they effectively wick away wetness to help reduce
trauma to the skin (review more
information on this topic in our Skin Care: Problems and
Solutions for the Individual with Alzheimer's Disease).
