I record this as part of the physical exam. The amount of detail depends on how pertinent they are to that particular patient (post stroke, dementia, other brain injury, pre-op evaluation, etc) or whether there are positive findings that need to be documented.
Not sure about whether they need a separate section.
I would be more interested in a separate section for past medical history that could be updated at any time (meaning whenever we get new information) and not just during an encounter.
Thank you.
