My mother-in-law is 83 and said she experienced several episodes of...in her words...a blue shroud passing from one side of her head to the other.  She also said she could not remember account numbers or passwords today (understandable at her age, but this is the first time it has occurred).
Hello thanks for asking from Chat Doctor for your health related queries can understand your concern. She is 83 years old, and it is common to see cognitive decline at this age. The problems of memory loss, inability to remember numbers or passwords could occur due to age related cognitive decline. But she has also shown symptoms like \"a blue shroud passing from one side of her head to other\" and this could occur due to some psychotic symptoms. These can also occur in dementia or due to some metabolic abnormality at her age. Consult a neuropsychiatric for her proper treatment and evaluation. For her cognitive decline and memory loss medicines like Donepezil, Semantic etc. can help. These medicines will reduce the progression of her cognitive decline, and she will feel better. Provide her warm loving support, and she will show improvement. Get her Blood pressure checked regularly to rule out any vascular complications. Thanks, hope this helps you. Take care
