Reducing
Risk Factors for Another Stroke
The principles used for preventing a first
stroke and for treating TIAs also apply to stroke patients. For those
whose stroke was ischemic, aspirin, warfarin or both will usually be
prescribed. Using a neurologist as the primary physician after a stroke,
rather than some other specialist or primary care doctor, significantly
increases the chance for survival. Some insurance companies may be
reluctant to pay for the service of a neurologist; in such cases,
patients or their families should be persistent in requesting the best
care possible during this important early period. Being treated
initially in a stroke unit instead of a general ward appears to play a
strong role for better long-term quality of life.
Candidates
for Rehabilitation
In all, 90% of stroke survivors experience
varying degrees of improvement after rehabilitation. With current cost
cutting, there is pressure to send elderly stroke victims directly to a
nursing home rather than try rehabilitation first, although one study
found that patients were three times more likely to return home from
rehab units than from nursing home. Not all patients, however, need or
benefit from formal rehabilitation. If the stroke is severe, intensive
training would not be very helpful; if the stroke is mild, patients
often improve on their own. To be admitted to rehabilitation, a patient
should be able to sit up for at least an hour, be able to learn and be
aware, and should have family members or close friends who can be active
participants in the rehabilitation process.
Certain early signs can help predict the best
and worst candidates for rehabilitation:
Dysphagia -- the inability to swallow -- is associated with a
higher mortality rate, possibly because of increased risk for infection
and malnutrition. Incontinence and the inability to recognize nonspeech
sounds that occur right after a stroke and a poor hand grip that is
still present after three weeks are indicators of severe problems.
Spasticity, on the other hand, may actually be
a good sign, because it indicates live nerve action. Patients who are
able to move their shoulders or fingers within the first three weeks
after having a stroke are more likely to recover the use of their hands
than patients who cannot perform these movements. The ability to feel
light pressure on the affected hand, however, makes no difference for
future hand movement.
Some
Rehabilitation Approaches
Because stroke affects different parts of the
brain, specific approaches to managing rehabilitation vary widely among
individual patients. Although dead nerve cells cannot regenerate,
undamaged brain cells often can take over their functions, and different
muscles can be trained to replace those that have been weakened. It is
very important that physical therapy be started as soon as the patient
is stable -- as early as two days after the stroke. Some patients will
experience the fastest recovery in the first few days but many will
continue to improve for about six months or longer. About 30% of
patients experience aphasia, which is particularly distressing. It is
necessary that the patient's family understand that this disability does
not necessarily impair the ability to think and partial or even complete
recovery is very possible. While professional speech therapy progresses,
the patient's caregivers should use and encourage the patient in
non-verbal communications, such as pantomime, facial expressions, and
pen and paper. Learning and using the sign-language alphabet may be
helpful both in communicating and improving small-motor dexterity.
Physical exercise relating to the disability caused by the stroke is, in
any case, important and may actually help repair the brain. One
rehabilitation program found good results with a program that used
equipment to retrain muscles and balancing skills. Physical therapy
combined with electrical stimulation and biofeedback techniques has also
been beneficial. Electrical stimulation of the throat may help patients
with dysphagia recover their ability to swallow faster. The use of an
amphetamine may help improve motor skills when combined with physical
therapy. Another interesting approach for patients with stroke in the
right hemisphere uses a special prism and sounds that help the patient
to regain the function in the left hemisphere, which suffers neglect
when the right hemisphere is damaged by a stroke.
Drug
Therapy for Rehabilitation
Drug therapy can sometimes help relieve
specific effects of stroke. For example, the drugs dantrolene (Dantrium),
baclofen, and injections of the deadly bacterial toxin botulism have
shown some promise in relieving spasticity. In one small study, the drug
bromocriptine (Parlodel), normally used for Parkinson's disease, was
helpful for patients with severe speech problems, improving their
ability to pronounce multisyllable words and to form sentences. Some
patients experience intractable hiccups, which can be very serious.
Among the drugs used for this condition are chlorpromazine or baclofen.
Certain drugs commonly taken for conditions
associated with stroke may actually slow recovery. They include drugs
used for high blood pressure, including clonidine and prazosin,
anticonvulsant drugs, the antipsychotic drug haloperidol, and the common
anti-anxiety drugs benzodiazepines.
Managing
the Emotional Consequences
Strokes
affecting the right hemisphere in the brain increase the patients risk
for post-stroke depression. Feelings of great distress are natural after
a stroke, in any case, but if depression is prolonged, it can impair
recovery. One study showed that people who suffered strokes and became
depressed were three times more likely to die within ten years than
stroke victims who were not depressed. There is a significantly
increased risk of suicide in patients with stroke, especially in women
and those under age 60. Anxiety disorder is also common -- occurring in
as many as 25% of patients -- and can be debilitating. The two disorders
may overlap, but drug treatments for each differ and may offset the
other. In addition, many drugs for psychologic disorders and other
problems that effect the central nervous system interfere with and can
delay rehabilitation. Skilled professional help is needed to determine
the most effective and safest treatments. Antidepressants, particularly
fluoxetine (Prozac) and similar so-called SSRI drugs, have been
beneficial in relieving post-stroke crying.
