The
common term “stroke” is
actually applied to several very different conditions,
with different causes.
The most common
form of stroke, known as ischemic stroke, occurs when
the blood supply is cut off to an area within the brain,
and brain cells begin to die due to oxygen deprivation.
Less common, but often more deadly, are hemorrhagic
strokes, which occur when a blood vessel or artery
bursts, causing bleeding in the brain.
Each year in
the United States, there are more than 700,000 strokes.
Stroke is the third leading cause of death in the country,
causing more serious long-term disabilities than any
other disease. Nearly three quarters of all strokes
occur in people over the age of 65. The risk of having
a stroke more than doubles each decade after 55. For
African Americans, the risk of stroke is greater and
more deadly---even in young and middle-aged adults.
While strokes
can be life-threatening and debilitating, new treatments
are available that can greatly reduce damage to the
brain. The key to minimizing stroke damage is recognizing
the signs of a stroke and getting medical treatment
with in the first hour of symptoms.
Signs of a
possible stoke include:
• Numbness or weakness
of the face, arm or leg (especially on one side);
• Confusion,
trouble speaking or understanding speech;
• Unexpected
trouble seeing in one or both eyes;
• Difficulty
walking, dizziness, loss of balance or coordination,
and
• Sudden severe headache with no known
cause.
The longer
blood flow is cut off to the brain, the greater the
damage. Also, many of the new treatments for stroke
patients are time-sensitive---meaning there’s
a limited window of opportunity for treatment. Clot-busting
drugs, such as tPA (tissue plasminogen activator) are
effective in treating patients suffering from ischemic
strokes, but must be administered within three hours
from the start of symptoms.
Despite advanced
treatments for stroke, many victims are left with functional
problems. The severity of damage often depends on the
size and part of the brain impacted. Patients often
suffer from full or partial paralysis, and difficulty
thinking or speaking, as well as emotional or behavioral
problems.
Comprehensive
stroke rehabilitation can improve the functional abilities
of stroke survivors, often helping people resume independent
living. In fact, that is the goal for stroke patients
at Merwick Care Center, a unit of Princeton HealthCare
System (PHCS), located in Princeton. In this facility’s 17 bed acute
rehab unit, stroke patients undergo intensive therapy
focused on helping them overcome their particular brain
injury and its resulting deficits.
Upon admission,
patients undergo a comprehensive evaluation by a team
of rehabilitation experts including a neuropsychologist,
occupational therapist, physical therapist, speech
pathologist, rehab nurse and physiatrist.
Neuropsychologists
use diagnostic tests to determine the specific location
of the brain damage and how the patient’s thinking,
behavior and emotions are affected. With a comprehensive
understanding of brain function, they can translate
how damage to a specific area of the brain pertains
to cognitive weaknesses.
For example,
damage to the left side of the brain may be associated
with language problems. In the back of the brain, or
occipital lobe, damage may result in difficulty with
visual processing. The front part of the brain affects
planning or decision-making functions, while the temporal
area (side of the head) affects memory.
Patients undergo
comprehensive testing and evaluations to help pinpoint
specific and often subtle, cognitive damage caused
by stroke.
The neuropsychologist
works with the rehab team to incorporate specific tasks
into therapy to redevelop these functions. Neuropsychologists
often help to facilitate rehabilitation, assisting
rehab team members to find more effective ways to communicate
and engage patients whose thought processes have been
impacted by stroke.
In addition
to the neuropsychological assessment, patients undergo
extensive evaluations to determine the stroke’s impact on their ability
to function. Occupational therapists assess patient’s
ability to complete the basic activities of daily living.
Physical therapists look at mobility issues, and speech
pathologists perform cognitive assessments, evaluate
speaking ability and/or any swallowing difficulties.
All of this
information is taken into account by team members,
who then develop a highly focused, comprehensive rehabilitation
plan for each patient. Every day, patients undergo
intensive rehabilitation that might include re-educating
muscles, re-learning how to walk, speak or swallow,
strengthening upper and lower extremities, learning
new ways to do regular activities or learning the use
of adaptive equipment.
Merwick Care
Center’s
staff of rehabilitation nurse extends the benefits
of therapy to 24/7 by incorporating rehabilitation
goals into the practical application of daily care.
These highly skilled nurses facilitate each patient’s
progress by providing an exceptional level of compassionate
care, while encouraging their patients’ independence.
On average,
inpatient rehab lasts from two to five weeks, depending
on the severity of stroke and residual damage. While
patients with more serious deficits may continue therapy
in a sub-acute environment, ideally the goal of rehab
at Merwick is to achieve a community discharge---to
send patients home. Additional services are available
through PHCS’s continuum of care
for stroke patients, including outpatient rehab or
home care.
Ultimately,
the recovery process following stroke may take a year
or more at various levels of care, but with new treatments
and comprehensive rehabilitation, recovery from stroke---and
a return to a productive and rewarding life---is possible.
