What is a stroke?
A stroke, also known as a “brain attack,” occurs when narrowed blood vessels or blood clots block blood flow to the brain, or when there is bleeding into the brain. As a result, the affected parts of the brain are deprived of vital nutrients and brain nerve cells begin to die almost immediately. Victims of stroke may experience a loss of vision, impaired sensory perception, problems with walking and talking, difficulty thinking or even death.

Age, gender and race can all affect your chances of having a stroke. In fact, those at greatest risk are African-American males between the ages of 65 and 74. Additional risk factors include:
High blood pressure (hypertension) – This is the leading risk factor for stroke. The only way to know if you have the condition is by visiting your doctor and having your blood pressure checked. If it’s too high, a treatment plan must be developed to bring it into normal range.
Smoking – Smoking has been linked to the buildup of fatty substances in one of the major arteries leading to the brain, a condition that can initiate a stroke. It also contributes to high blood pressure, a reduction of oxygen carried to the brain and thickening of the blood, which makes it more likely to form clots.
Heart disease – Common heart disorders such as irregular heart beat, valve defects and enlargement of one of the heart’s chambers can result in blood clots that may break loose and block vessels leading to the brain. If you or a family member have a heart condition, work closely with your physician to determine the best course of treatment.
Diabetes – Diabetes affects glucose levels in the body and can also cause destructive changes in blood vessels, including those in the brain. Effective diabetes management is essential to avoid potentially devastating complications, including reduced circulation and stroke.
Heredity – People who have a history of stroke in their family or in their own personal medical history are at increased risk.
All health conditions that may increase the possibility of stroke should be carefully monitored by a doctor to prevent the onset of a life-threatening incident.
A warning sign of stroke is an indication that a part of the brain may not be receiving enough oxygen. A person experiencing any of the following symptoms should seek immediate medical attention:
- Sudden numbness or weakness of the face, arm or leg, especially concentrated on one side of the body
- Sudden blurred vision in one or both eyes
- Sudden confusion or trouble speaking or understanding
- Sudden severe headaches unlike any the person may have had before
- Sudden difficulty in walking, involving dizziness,loss of balance or coordination
- Double vision, drowsiness, nausea or vomiting
These brief episodes are known as transient ischemic attacks (TIAs), often referred to as “mini-strokes.” Although TIAs may last only a few minutes (or up to 24 hours) and then completely resolve, it is important to take them seriously and seek medical attention without delay.
Stroke impacts people in many different ways depending on the parts of the brain that have been affected. If you are caring for someone who has suffered a stroke, it is important to be prepared for a number of physical and behavioral changes. These may include:
- Physical symptoms – Stroke often causes people to lose mobility and feeling in an arm or leg. They may also suffer from a reduction in sight on one side. Consequently, stroke survivors may feel off balance, “neglect” the weaker side, and have trouble functioning as they once did.
- Perception – Stroke can affect a person’s ability to see, feel and think. When this happens, perception of everyday objects can change, causing the individual to bump into things more frequently.
- Hearing – Although a stroke does not cause hearing loss, damage to the part of the brain controlling language interpretation can make it difficult for stroke survivors to understand speech and sounds.
- Speech – Stroke can also significantly affect a person’s ability to speak. A stroke that affects the motor areas of the brain can affect the muscles used in talking, resulting in slower, slurred or distorted speech. A stroke in this area of the brain may also prevent a person from being able to translate his or her thoughts into the correct words.
- Eating – When one side of the mouth or palate is weak, it can cause problems with chewing and swallowing resulting in an increased risk of choking.
- Thinking – A stroke can affect a person’s ability to think through everyday tasks clearly, resulting in confusion about the logical sequence of events involved in performing a particular task.
- Emotions – Sudden mood swings that may include crying or laughing for no apparent reason are common. Stroke victims may also suffer from bouts of depression.
Clearly, a stroke can be severely disabling, not only physically, but also mentally, behaviorally and emotionally. As such, stroke survivors must be treated with patience and compassion.
Depending on the level of need, there are a number of care options available. Each employ a coordinated team of professionals including skilled nurses, therapists, dietitians and social workers – all working with the patient’s doctor to ensure the highest level of care. Most of these programs are available right in your neighborhood.
Adult Day Health Care – ADHC provides an opportunity for stroke victims to socialize in a medically supervised environment while offering a measure of relief to the at-home caregiver. Experienced professionals also provide for on-going health needs, including physical, occupational and speech therapies.
Short-Term Rehabilitation – After the need for acute care has passed, short-term rehabilitation services are often prescribed to help restore patients to their highest level of function and independence. Typically provided in skilled nursing centers, the goal of short-term rehab is to return patients to their homes or alternate level of care as quickly and safely as possible.
Long-Term Home Health Care – These programs utilize a complete team of healthcare professionals who come into the home to provide sub-acute care and rehabilitation in accordance with a prescribed treatment plan.
Residential Health Care Facilities – These facilities offer patients both short- and long-term rehabilitation, 24-hour skilled nursing supervision, specialized support services and help with activities of daily living.
