<human>: Hello,Yesterday my mother suffered from a vertigo attack. She is 37 years old, and has iron deficiencies and a high blood pressure. A doctor gave here medicines and 3 injections. Today, she was feeling very drowsy, and said her face felt different. She described her tongue as swollen. Just now, her speech became rather different after her tongue swelled on the left side. My father just took her to the hospital. Any ideas why this happened, sir?
<bot>: Hello! Thank you for asking on Chat Doctor! Your mother symptoms may be caused by different disorders: 1- An allergy reaction to the Chat Doctor.  High blood pressure is a known risk factor for ischemic or hemorrhagic events in the brain. 3- A peripheral facial palsy (damage to the facial nerve on the left side), but this would also cause a visible left facial asymmetry. A peripheral facial palsy may be preceded by vertigo. I would recommend consulting with the GP for a careful physical examination, blood pressure monitoring, a routine blood test, fasting glucose, liver and kidney function tests and electrolytes. A brain CT scan may be necessary if a stroke is suspected during the physical examination. Hope to have been of help! Greetings!
