Symptoms

The symptoms depend on the location of the stroke within the brain and how severe the losses are, so the symptoms can be very diverse.
The symptoms may include:


Sudden onset of weakness or paralysis on one side of the body, i.e. in an arm, leg or one side of the face;


Speech problems occurring together with lameness, usually in the right side, and difficulties in understanding spoken language of others;


Problems seeing (double vision, blurred vision, temporary loss of vision in one eye, unilateral loss of a visual field);


Dizziness, with unsteady gait, loss of balance or coordination;


Sudden clouding of consciousness or even loss of consciousness;


Nausea, vomiting, confusion;


Sudden very severe headache.

About every third stroke is preceded by a sudden disturbance in the brain’s blood flow known as a transient ischemic attack (TIA). TIAs may last only a few minutes, at most 24 hours, but they are important warning signs of a stroke which can threaten soon.
