- She developed neurological symptoms including short-term memory problems, difficulty concentrating, irritability, loss of appetite, and heart palpitations.
- Medical history revealed high blood pressure, anxiety, depression, hypothyroidism (managed for over a decade), and a recent dosage increase of thyroid medication.
