As the number one cause of disability in adults, stroke affects a diverse range of people. If you are one of them, you know stroke may cause severe spasticity. You should also know it's possible to manage your symptoms and live more comfortably – with a device developed by Medtronic.
A stroke occurs when a blood clot blocks a blood vessel or artery. It also can occur when a blood vessel breaks, interrupting blood flow to an area of the brain. A stroke kills brain cells in the immediate area.
When brain cells die during a stroke, abilities controlled by that area of the brain are lost. These abilities may include speech, movement, and memory. The way a stroke affects you depends on where the stroke occurs in the brain and how much of the brain is damaged.1
An ischemic stroke is the most common kind of stroke. It's caused by a blood clot that blocks or plugs a blood vessel in the brain. A hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes," or transient ischemic attacks (TIAs), happen when the blood supply to the brain is briefly interrupted.2
A stroke can happen to anyone. However, you can control or treat many major risk factors, including:3

The following screening tools are most often used to determine stroke risk, but they also can be used to diagnose stroke:4
If you've suffered a stroke, you may begin to experience spasticity.
Spasticity is caused by damage or injury to the part of the central nervous system (the brain or spinal cord) that controls voluntary movement. This damage disrupts important signals between the nervous system and muscles, creating an imbalance that increases muscle activity or spasms.
Spasticity can make movement, posture, and balance difficult. It may affect your ability to move one or more of your limbs, or to move one side of your body. Sometimes spasticity is so severe that it gets in the way of daily activities, sleep patterns, and care giving. In certain situations, this loss of control can be dangerous for the individual.
