Hi Sue,
I'm sorry to hear about your mother's stroke and the episodes that you are describing.
Sundowners Syndrome (Sundowning) - agitation, low mood, and changes in behaviour and thinking that occur before dark, is not commonly associated with stroke, but rather dementia.
I'm glad to hear that she is seeing a psychologist. She may also benefit from a full medical examination and medication review. Speak to her doctor about this, as well as whether a referral to a neurologist is warranted.
Finding the cause of your mother's Sundowning is an important step to getting the best management.
Alzheimer's Australia gives some practical strategies on how to reduce the severity of Sundowning symptoms on their website.
If we can be of any further assistance, please don't hesitate to contact our team of health professionals on 1800 787 653 (Mon-Fri 9am-5pm EST).
Best wishes,
Alana - StrokeLine
