[Q]: Question: Do serial montreal cognitive assessments demonstrate reversible cognitive impairment in patients with acute transient ischemic attack and minor stroke?
Answer: Acute temporary cognitive impairment after TIA/minor stroke is common. The MoCA is sensitive to these changes, but the MMSE is not. Routine cognitive assessment after TIA/minor stroke may be warranted and relevant to return to activities even when other neurological deficits are not evident.
[A]: yes

[Q]: Question: Is diagnostic lobectomy routinely required to exclude malignancy in thyroid nodules greater than four centimetres?
Answer: Many patients with large thyroid nodules undergo thyroidectomy for symptom relief alone, regardless of their FNAC results. In such patients where other clinical indicators for thyroidectomy are not present, a benign FNAC result can reassure both patient and surgeon that mandatory surgical excision is not needed to exclude malignancy.
[A]:
no
