What is a Stroke?
Stroke is the 5th leading cause of death in America.
Per the National Stroke Association, stroke is the fifth leading cause of death in America and a leading cause of adult disability. Yet, research shows that too few people know what a stroke is and how to recognize when stroke is happening. A stroke happens when blood flow to an area of the brain is cut off. Brain cells are deprived of oxygen and begin to die. A stroke can cause you to permanently loose speech, movement and memory.
There are two types of stroke, hemorrhagic and ischemic.
Hemorrhagic strokes are the least common type of stroke. Only 15% of all strokes are hemorrhagic, but they are responsible for about 40% of all stroke deaths.
A hemorrhagic stroke is either a brain aneurysm burst or a weakened blood vessel leak. Blood spills into or around the brain and creates swelling and pressure, damaging cells and tissue in the brain. There are two types of hemorrhagic stroke:
An intracerebral hemorrhange is the most common hemorrhagic stroke, happening when a blood vessel inside the brain bursts and leaks blood into surrounding brain tissue. The bleeding causes brain cells to die and the affected part of the brain stops working correctly. High blood pressure and aging blood vessels are the most common causes of this type of stroke.
Sometimes intracerebral hemorrhagic stroke can be caused by an arteriovenous malformation (AVM). AVM is a genetic condition of abnormal connection between arteries and veins and most often occurs in the brain or spine. If AVM occurs in the brain, vessels can break and bleed into the brain. The cause of AVM is unclear but once diagnosed it can be treated successfully.
A subarachnoid hemorrhage type of stroke involves bleeding in the area between the brain and the tissue covering the brain, known as the subarachnoid space. This type of stroke is most often caused by a burst aneurysm. Other causes can include arteriovenous malformation (AVM), bleeding disorders, head injuries, and blood thinners.
Ischemic stroke occurs when a blood vessel carrying blood to the brain is blocked by a blood clot, causing blood not to reach the brain. High blood pressure is the most important risk factor for this type of stroke. Ischemic strokes account for about 87% of all strokes. An ischemic stroke can occur in two ways:
In an embolic stroke, a blood clot or plaque fragment forms somewhere in the body (usually the heart) and travels to the brain. Once in the brain, the clot travels to a blood vessel small enough to block its passage. The clot lodges there, blocking the blood vessel and causing a stroke. About 15% of embolic strokes occur in people with atrial fibrillation (Afib). The medical word for this type of blood clot is embolus.
A thrombotic stroke is caused by a blood clot that forms inside one of the arteries supplying blood to the brain. This type of stroke is usually seen in people with high cholesterol levels and atherosclerosis. The medical word for a clot that forms on a blood-vessel deposit is thrombus. Two types of blood clots can cause thrombotic stroke:
Large vessel thrombosis is the most common form of thrombotic stroke and it occurs in the brain’s larger arteries. In most cases it is caused by long-term atherosclerosis in combination with rapid blood clot formation. High cholesterol is a common risk factor for this type of stroke.
Small vessel disease happens when blood flow is blocked to a very small arterial vessel (small vessel disease or lacunar infarction). Little is known about the causes of this type of stroke, but it is closely linked to high blood pressure.
Stroke Care and Telemedicine
Telemedicine increases the quality and convenience of healthcare services. It can help provide patients with better, faster, and more specialized care. Doctors can provide more convenient, real-time interactions with patients and improve communications with other medical staff.
With a stroke, time is brain.
At Parham Doctors' Hospital, a Joint-Commission Certified Primary Stroke Center, our expert doctors use on-site examinations and telemedicine capabilities to quickly access a neurologist at Henrico Doctors' Hospital who can also evaluate the patient through a camera and microphone. In addition, the patient can see and interact with the neurologist and see scans and reports of their tests which can also be shared with a specialist.
This technology leads to faster administration of the clot buster drug which can lead to improved outcomes in as little at 6 months. It is more convenient for the patient as they can receive specialized care faster, no matter what time of the day or night. Our own specialized neurologists will utilize this technology and continue to care for the patient throughout their hospital stay.
The Inpatient Physical Rehabilitation Center at Parham Doctors’ Hospital has long been recognized as a community leader in the rehabilitation of patients with physical limitations secondary to stroke, trauma, spinal cord injuries, orthopedic injuries and surgery, amputations, chronic pain, cardiac and pulmonary disorders, and other neurological and musculoskeletal conditions. Our robust program offers unique treatment therapies with a team solely dedicated to yours or your loved one's recovery.Learn More About Inpatient Rehabilitation at Parham Doctors' Hospital
Stroke Support Group
The Stroke Survivor Group at Parham Doctor’s Hospital is comprised of stroke survivors, both inpatient and outpatient, and their families and caregivers. The group meets monthly to exchange information about recovery and resources. Meetings also feature speakers from a variety of sources including authors, therapists and social connections. The meetings are held on the last Thursday of each month with the exception of November and December. The goal of the group is to provide stroke education and information exchange. Meetings are from 3:30 to 4:30 at Parham Doctors Hospital 7700 E Parham Rd Richmond, 4th floor, Multipurpose Room. If you are interested in being notified of future meetings, please email. Dr. Linda Pattee at email@example.com.
