Transient Ischemic Attack (TIA) is triggered by disruption in blood flow to certain parts of the brain for some time. It is also known as mini stroke as the symptoms mimic those of a stroke. According to Harvard Heart Letter December 2015, often people mistake such signs as indications of low blood sugar or “trick knee” and do not seek medical advice, which can lead to grave consequences. The symptoms of TIA which are more or less like those of stroke can cause:
- Sudden numbness or weakness in the face, arm, or leg on one side of the body
- Double vision and temporary loss of vision in one eye
- Loss of comprehension and trouble speaking
- Uncoordinated walking
- Loss of balance, dizziness
Depending on the part of the brain affected by ischemia the symptoms of stroke and TIA may vary widely. TIA and stroke lead to decreased blood supply to a specific region of the brain and thus affects particular senses related to that region only like speech, vision, numbness of one side of the body.
However, other neurological conditions such as migraine ,hypoglycaemia and seizures which often present similar symptoms as TIA and stroke bring about various generalized symptoms as fainting ,tingling sensations in the limbs. According to Dr Caplan distinguishing between different neurological conditions is not easy and therefore any of these signs should not be taken lightly and one should not indulge in self medication instead should immediately consult a doctor and get further investigations done.
