At the age of fifty, he is a young man.
While a CAT scan is helpful, an MRI and an MRA would be more appropriate. There not nothing the CAT can do that the MRI and the MRA can do better and with less hazard.
There may be several problems going on.
Fatigue that varies suggests a glucose utilization syndromes, perhaps diabetes, and what is called an hba1c test should be performed. A thyroid disorder is another possibility. Weakness, faitiguie and fainting could be cardiogenic, and a stress test would be adviseable.
Thank goodness he has a concientious wife who cares about him.
The "failing to remember" is called retrograde amnesia and it means he requires a neurological examination.
For my two cents, I would get him set up with a teaching hospital and a team of physicians, if possible, rather than a single general practicioner. This is not always possible. I amtroubled by any patient who experiences a sudden inexplicable "loss of consciousness". That is a red flag. The signal to go to "general quarters". When he blacked out he should have gone immediately to an emergency room. Under United States hospital protocols he would have been admitted and "entered into the system" for a "round robin" by all appropriate specialists. The hospitals are usually pretty good in evaluating such problems. The question is "did he fall" or "did he lose consciousness". That is a very important detail.
Good luck, and post back when they come to a provisional diagnosis.
Hi
Welcome to the MedHelp forum!
Since your husband complains of exhaustion even after a whole night’s sleep, he could be suffering from sleep disorders and inadequate sleep. One may appear to sleep the customary 7-8 hours and yet not get the required amount of sleep in the right pattern. Hence it is important to get sleep studies done. This can be the cause of unexplained falls.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
is he falling when rising from a sitting position? Is he on any medication? Has she checked his b12 folate thyroid CBC?
There could be many reasons for unexplained falling from the benign like an inner ear infection to the serious like brain tumors.Unfortunately the only way to know what the cause is, is for the Dr. to run tests and give his medical opinion. The best thing to do is keep the doctor's appointment and be completely honest about all the symptoms even if you think they are unimportant details. Be sure to mention the exhaustion, and if he is not remembering the falls or "blacking out" before he falls make sure to tell the Dr. that as well. Hope everything is fine and goes well. Best of luck!
it could be high blood pressure i guess , but seeing a doctor is good idea for him.
