Q

What is nominal aphasia? Where in the brain is affected?

A

Unable to name familiar objects but language is otherwise preserved - it can occur as part of other aphasic syndromes

When it occurs on its own, it suggests an inferior parietal lesion - angular gyrus

Q

80 y/o woman with 3 month Hx of falls. Has CKD, mild dementia and is awaiting R knee replacement for OA. Struggles to climb stairs due to knee pain. Takes paracetamol and 2 weeks ago started on codeine. What do you do?
