My father has had two episodes of what they call Transient Global Amnesia . However, I am worried that it could be something more life threatening and wish they would do more investigative tests to rule things out. First episode was march last year- he is 57 and he was outside in winter, not to cold of a day shovelling snow and cutting up wood- physical work for sure. he forgot what he was doing and had memory loss that took approx 6 hours to subside. his long term memory intact but that day he couldn t remember the morning and a few things from the week before he forgot- ex he forgot he was renovating his own bathroom. went to near hospital. blood work, ECG done, only thing they said was low B12. He had CT done and a 48 hour CT repeated.. they said it was clear.. He was on a medication for high cholesterol, ASA and pariet prior to event. they increased ASA to 325 mg in case.. but since lowered it back to 81 mg a few months ago. Today he had second episode- almost 10 months in difference. He was shovelling snow, and it is cold weather. came into the house and couldn t remember presenting same way as last march. Went to hospital they did blood work and sent him home.. his memory is still not back and he is discharged home.. I am concerned...
Please visit a neurologist. A magnetic resonance imaging or a MRI can give a clearer picture. It might be a type of dementia. Please make a note of other changes you notice in him.
