Frequently Asked Questions (FAQ)
What tests are used to diagnose a stroke?
When a stroke is suspected, doctors in the emergency room will act quickly. The primary diagnostic tools are brain imaging tests. A CT (computed tomography) scan can quickly reveal if there is bleeding in the brain, helping to distinguish between an ischemic and hemorrhagic stroke. An MRI (magnetic resonance imaging) can provide a more detailed image of brain tissue and can detect damage from an ischemic stroke earlier than a CT scan. Other tests may include blood tests and an electrocardiogram (ECG) to check heart rhythm.
Can the damage from a stroke be reversed?
When brain cells die during a stroke, the damage is permanent. However, the brain is incredibly resilient. Through rehabilitation, other parts of the brain can learn to take over the functions of the damaged areas. While a full recovery is not always possible, many stroke survivors can regain a significant amount of function and lead fulfilling lives. The extent of recovery depends on the severity of the stroke and the speed of treatment.
Is a TIA (mini-stroke) as serious as a major stroke?
A TIA does not cause permanent brain damage, so in that sense, it is not as immediately devastating as a major stroke. However, it should be treated with the same urgency. A TIA is a powerful predictor of a future stroke; about one-third of people who have a TIA will have a major stroke within a year if they do not receive treatment. Consider a TIA a critical warning sign that requires immediate medical attention to identify and manage the underlying cause.
How does stress affect stroke risk in women?
Chronic stress can indirectly increase stroke risk. It can contribute to high blood pressure, unhealthy eating habits, poor sleep, and a more sedentary lifestyle—all of which are established risk factors for stroke. Managing stress through techniques like mindfulness, gentle exercise, and social connection is an important component of a heart-healthy and brain-healthy lifestyle.
