Rapid Memory Changes May Signal Treatable Causes Beyond Ageing
People sometimes forget names or misplace things, and that can happen as they get older.
But a big change that happens quickly is different from an occasional lapse.
Trouble finding familiar places, new confusion, mood changes, poor sleep, or difficulty with everyday tasks are also reasons to seek medical advice.
The article describes a woman whose memory and other abilities changed over about two months.
Tests suggested that inflammation involving the brain might be causing her symptoms.
Some forms of this condition can respond to treatment.
She received medicines that calm the immune system and gradually improved.
The article advises families to notice how quickly changes happen and discuss them with a doctor.
Memory problems that worsen noticeably over weeks or months warrant medical evaluation rather than being automatically attributed to ageing.
Other warning signs can include confusion, getting lost in familiar places, personality changes, sleep disturbance, or difficulty with routine tasks.
A 61-year-old woman with rapidly developing memory and visual-spatial problems was assessed after an initial dementia diagnosis.
An antibody finding and brain FDG PET scan supported the possibility of autoimmune encephalitis, although her MRI was normal.
After immunotherapy, including steroids, IVIG and later rituximab, she gradually recovered close to her previous cognitive functioning.
