<s>[INST] Hi I am experiencing some numbness on one side of my face. It started about 6 hers ago and soon after the numbness appeared I got a bad headache. The headache disappeared but after I would loose track of what I was saying and I would be thinking one thing and I would say something different not realizing it. Is this normal? [/INST] Hello! I read your question and understand your concern. I think that these symptoms may be caused by a small stroke. I would like to know if you  have measured your blood pressure. Do you suffer from arterial hypertension or diabetes ? The headache is not a common symptom in stroke, but it may be related to migraine, high blood pressure etc. I would recommend to consult the neurologist, have a good neurological examination, a full blood work, a blood lipids analysis and a brain CT scan. Further tests like cardiac check up and Doppler ultrasound of the carotid vessels may be needed to establish the cause. Hope to have been of help. Best wishes!Dr. Abaz Quka </s>
