She receives assistance with physical chores such as shopping and cleaning, but is still able to do light tasks such as tidying the house and cooking her own meals. She does not undertake any exercise activities. She has a history of hypertension and her blood pressure measured today is 145/90. She has not been diagnosed with diabetes or coronary heart disease. Mrs Tim has presented today at an Emergency Department, Royal Melbourne Hospital after experiencing an episode of blurred vision, difficulty speaking and dizziness. She did not lose consciousness and did not experience muscle weakness. The episode commenced about an hour ago and lasted for approximately 20 minutes. She was not asleep when the symptoms commenced. After arriving at hospital, a CT scan was performed and no tumour was observed. An MRI scan is about to be performed.
