What are the two types of stroke?
There are two types of stroke, each caused by a unique event.
An ischemic stroke, which accounts for about 85% of all strokes, occurs when the arteries to the brain are blocked or partially obstructed by a blood clot. The two most common types of ischemic stroke are:
A thrombotic stroke is caused by a blood clot forming in an artery that supplies blood to the brain. A clot may be caused by one of a number of different artery conditions, the most common being plaque build-up.
Embolic stroke occurs when a blood clot forms from the brain (such as in the heart), travels through the bloodstream and gets lodged in a brain artery.
The second type of stroke, called a hemorrhagic stroke, occurs when a blood vessel in the brain leaks or ruptures. This is a less common type of stroke than ischemic, yet is more likely to be fatal to the victim.
The two most common types of embolic stroke are:
- Intracerebral hemorrhage occurs when a blood vessel in the brain bursts and damages the cells in the surrounding tissue.
- Subarachnoid hemorrhage is caused by an artery near or on the surface of the brain bursts, and the blood spills into the space between the brain and the skull.
Although not technically a stroke, when blood flow to part of the brain is disrupted for a short period of time, it is called a transient ischemic attack (TIA). The effects of these attacks mimic stroke-like symptoms and may be an important pre-stroke indicator for the patient.
What are the warning signs of a stroke?
The American Heart Associate (AHA) uses the acronym FAST as a recommendation for how to spot signs of stroke. According to the AHA, FAST refers to:
- F-Face Drooping
- A-Arm Weakness
- S-Speech Difficulty
- T-Time to call 911 (for anyone exhibiting the above symptoms)
Other common stroke symptoms include:
- Sudden confusion
- Trouble with speech or understanding speech
- Numbness or weakness of the face, arm, or leg (especially on one side of the body)
- Trouble with vision
- Trouble with gross motor skills such as walking
- Severe headache
What are the leading causes of stroke?
- High blood pressure
- High cholesterol
Are strokes preventable?
Studies show that 80% of strokes are preventable by living a healthy lifestyle, despite stroke being the 5th leading cause of death for Americans and the leading cause of adult disability.
Is Neurofeedback Therapy a clinically proven treatment for stroke?
There are many research studies that show positive support for neurofeedback as a treatment for stroke. Please see a few examples below, and don’t hesitate to contact MyBrainDr for additional information and studies.
Specific effects of EEG based neurofeedback training on memory functions in post-stroke victims.
“About 70 % of both patients and controls achieved distinct gains in neurofeedback performance leading to improvements in verbal short- and long-term memory, independent of the used neurofeedback protocol. The SMR patient group showed specific improvements in visuo-spatial short-term memory performance, whereas the Upper Alpha patient group specifically improved their working memory performance. Neurofeedback training effects were even stronger than the effects of traditional cognitive training methods in stroke patients. Neurofeedback training showed no effects on other cognitive functions than memory.”
“Post-stroke victims with memory deficits could benefit from neurofeedback training as much as healthy controls. The used neurofeedback training protocols (SMR, Upper Alpha) had specific as well as unspecific effects on memory. Hence, neurofeedback might offer an effective cognitive rehabilitation tool improving memory deficits of stroke survivors.”
Effect of neurofeedback and electromyographic-biofeedback therapy on improving hand function in stroke patients.
From the Abstract:
“This study was designed as a preliminary clinical trial. Thirty patients with stroke entered the study. Hand function was evaluated by the Jebsen Hand Function Test pre and post-intervention. Neurofeedback training was aimed at enhancing sensorimotor rhythm after mental motor imagery.”
“Hand function was improved significantly in the 3 groups. The spectral power density of the sensorimotor rhythm band in the neurofeedback group increased after mental motor imagery. Maximum and mean contraction values of electrical activities of the APB muscle during voluntary contraction increased significantly after EMG-biofeedback training. Patients in the neurofeedback and EMG-biofeedback groups showed hand improvement similar to conventional OT. Further studies are suggested to assign the best protocol for neurofeedback and EMG-biofeedback therapy.”
