Dementia 2

Continuing my learning experiences with patients with dementia.
The physio and I were asked to assess the mobility of a 78 year old lady described as "pleasantly confused".
She was resting in bed and we assessed her ability to move in the bed, go from supine to SOEOB, STS - all achieved independently with supervision including verbal prompts and reminders. Ambulation was with a WZF + 1 min assist with frame + verbal prompts - to take a larger step with her left foot (previous CVA). The physio recorded all this in the notes and included a comment - mobility may fluctuate secondary to dementia.
The next day the physio asked me to take this patient for a walk. On this day the patient needed 2 mod assist to stand from chair, 1 max assist in standing, 2 mod assist with ambulation with WZF + verbal prompts every three to four steps as the patient would just stop and needed to be told to take a step and we just had to wait ( the physio described this as being just like a Parkinson's patient).
This experience enable me to understand very quickly the physio's comment about fluctuating mobility. I will now be aware of this possibility with future clients I assess , particularly when noting mobility recommendations for nursing and other staff.
