Symptoms of a mini – stroke may include one or more of the following: Weakness or numbness in your arms and/or legs, usually on one side of the body. Dysphasia (difficulty speaking) Dizziness. Vision changes. Tingling (paresthesias) Abnormal taste and/or smells. Confusion. Loss of balance.
However, the signs of TIA are not as easily identifiable. They include severe headache, dizziness, trouble seeing in one or both eyes, and unexplained confusion. Despite 35 percent of respondents having reported one or more of these symptoms, most of them (77 percent) had never heard of TIA .
This type of dementia usually affects people aged 60 to 75 and is more common in men than women. Even though TIAs can be unnoticeably small , the damage to the brain adds up over time. When the blood flow to the brain is blocked, brain cells don’t get oxygen and nutrients.
Your treatment for a TIA may include taking medicines to prevent a stroke or having surgery to reopen narrow arteries. Medicines may include aspirin, clopidogrel, dipyridamole with aspirin, or warfarin. If your carotid arteries are significantly narrowed, you may need a procedure to widen the arteries.
– Warning signs of an ischemic stroke may be evident as early as seven days before an attack and require urgent treatment to prevent serious damage to the brain, according to a study of stroke patients published in the March 8, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology.
A TIA usually lasts only a few minutes and doesn’t cause permanent damage. Often called a ministroke, a transient ischemic attack may be a warning. About 1 in 3 people who has a transient ischemic attack will eventually have a stroke , with about half occurring within a year after the transient ischemic attack.
If necessary measures are taken within the first hours of the symptoms, damage to the brain cells can be reduced. Other symptoms include sudden arm, leg or face weakness, sudden confusion or speaking, sudden trouble seeing, sudden trouble with balance and a sudden severe headache with no known cause.
If you have other medical conditions, those may worsen if you are dehydrated . Some studies have also shown a connection between dehydration and the body’s ability to recover from transient ischemic attack ( TIA or mini-stroke ).
A stroke is often described as a “brain attack.” Part of the brain is robbed of the oxygen and blood supply it needs to function, because a blood vessel to part of the brain either has a clot or bursts. The longer a stroke goes untreated , the more brain damage can occur.
Table 2 summarizes the main outcome measures by age groups. Stroke fatality at discharge was 5.7% (age <59), 8.6% (age 60 to 69), 13.4% (age 70 to 79) and 24.2% (age > 80 ; P<0.001). Patients over age 80 had also higher risk-adjusted stroke fatality when compared with patients younger than 80 years old.
The blockage in the blood vessels responsible for most TIAs is usually caused by a blood clot that’s formed elsewhere in your body and travelled to the blood vessels supplying the brain. It can also be caused by pieces of fatty material or air bubbles.
Transient ischemic attack and minor stroke are highly predictive of a subsequent disabling stroke within hours or days of the first event. The risk of subsequent stroke after a transient ischemic attack is between 2% and 17% within the first 90 days after the initial event.
Tests will be done to rule out a stroke or other disorders that may cause the symptoms: You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests , but TIAs will not. You may have an angiogram, CT angiogram, or MR angiogram to see which blood vessel is blocked or bleeding.
For people who have had a stroke: Aspirin can help prevent a second stroke or a transient ischemic attack ( TIA ), which is often a warning sign of a stroke. For people who have never had a heart attack or stroke: Talk to your doctor before you start taking aspirin every day. Aspirin lowers the risk of heart attack.
