Are my mother's symptoms indicative of a stroke or something serious?

Hi doctor,

My 58 years old mother is under treatment for hypothyroidism, hypertension, osteoarthritis of knee joints, and mild anemia. Her hemoglobin is 10.5 to 11.0 g/dL. She is currently on the following medicines, Eltroxin 50 mcg, Olmezest 20 mg, Gemcal D3, Uprise XT, and Folvite. Six months back, one day after breakfast, she had reported an incident of reeling of head and darkness in eyes, which got normalized after she laid down on the bed. She also had a fever (100 to 101 F) with cold and cough that time, which took 3 to 4 days to settle down with antibiotics. One day after lunch, she again reported reeling of head and darkness in eyes, after which she got bent towards left side with her left-hand palm shaking for 15 to 20 second. And she was almost about to fall, which was stopped by us. She seemed to be in a subconscious state for 3 to 4 minutes, and she stared at something during that time. When we attempted to talk to her, initially she could make out only some sounds, followed by normal words, but in a strange voice, which got normal the next moment. However, coming back to sense, she was worried about the ongoing health issues of her son, and she had no memory of the incident at all. She was back to normal activities in next 10 minutes, and she did not report any arm or leg pain during that time. She also had a little cold the previous day, for which she took Cetirizine tablets. We consulted a doctor after 5 to 6 such incidents, who mentioned this as a case of sodium and potassium imbalance due to viral infection. He also examined her physically, and he said that her BP is 122/82 mmHg. As there was no history of convulsion, as well, without ordering for any further investigations. However, I would like to summarize a few symptoms as follows, which keep me worried. She reported feeling very tired and sleepy until at least two weeks of the incident. She had quite a few occurrences of constipation followed by gastritis 5 to 6 times of motion along with weight loss in the last 3 to 4 months. After the day of 5 to 6 times of motion, she reported feeling heaviness in legs, difficulty in walking along with a severe headache right from the morning. When we reported this to our doctor, he asked to test her sodium (138.4 mEq/L) and potassium (3.72 mEq/L) levels, which came back normal. Since the last couple of months, she felt a significant increase in her left knee joint pain, which I am not sure if totally because of existing osteoarthritis or not. Since the last couple of months, she felt difficulty in lifting heavy objects, especially, with the left hand and to some extent with right hand too. I have attached her recent routine test reports along with the doctor's prescription. Could you please review the incident along with the reports? Is it a stroke or Transient ischemic attack (TIA) or something serious?

Hello doctor,

Thank you for the response. I would like to clarify a few more things, just in case they give any further clue. Both incidents had happened in sitting position itself. There was no change in position before she got a dark vision. The early morning headaches had happened only after the day she had 5 to 6 times of motion (not loose motion). This is not a daily symptom. Symptoms like the increase in left knee joint pain and difficulty in lifting heavy objects through the left hand are persistent since past couple of months. Her kidney function test (KFT) tests were done last year, which mostly came normal (BUN was 14 and creatinine is 0.8), although liver function test (LFT) was not yet done. Based on the details we know so far, can I request your advice on kind of incident it had been? Was it a stroke or transient ischemic attack (TIA)? Were the sodium (138.4) and potassium (3.72) levels fine? What do you feel the cause of too much fatigue and sleepiness for a couple of weeks after the incident?

Thank you doctor,

It is a follow-up to our previous consultation with my mother (59+ Y). As advised by you, I got a physical check-up done for her and an orthopedic consultation, which mostly went fine. She also did an X-ray for both of her knee joints, which shows mild to minor osteoarthritis changes along with mild soft tissue swelling in the knee joints. Her blood pressure (BP) was checked in both sitting (left arm - 110/80 mmHg and sleeping positions (right arm - 120/72 mmHg), which, per the medicine doctor, were good. She tried Stamlo 2.5 instead of Olmezest 20. However, due to feet swelling, she reverted to Olmezest 20 only. Her iron tablet is also stopped, and she repeated complete blood count (CBC) and erythrocyte sedimentation rate (ESR) after six weeks, which indicates no change in hemoglobin (11.1). I have also uploaded the complete report for your kind review. Apart from BP medicine, she is currently on Eltroxin 50 mcg, Kondro OD (for 3-months), and Cobadex CZS (for 10-days every month). 1. Since the BP difference in sitting and sleeping positions is within ten, could these differences occur due to the previously discussed incidents? What I am worried about is how to prevent such occurrences in the future? 2. What could have caused the apparent change in consciousness during the incident? Also, she used to be very sleepy and tired for almost two weeks following the incident, which was unusual for her. Also, the incident had occurred while she was too worried about the family health issues. Does panic have something to do here?
