Questions
What is the possible diagnosis ?
How would you manage this?
Consistent with mixed AD and vascular dementia with Parkinsonism. Need to ensure fluid repleted- may need fludrocort if persistent . Can try small doses of levodopa but reponse may not be great— may worsen postural hypotension. Replete B12. Bone health screening, calcium and vit D supplement. Dietitian— high protein and balanced diet, PT gait/balance/walking aid, OT home falls hazard/equipment/carer training
