Marziya Hosseini lost part of her short-term memory after the stroke and remains hospitalized, they added.
Despite her condition, judicial authorities issued a new summons dated October 26, giving her five days to report to the Qeshm Public and Revolutionary Prosecutor's Office on a Persian Gulf island that was the subject of her investigations.
Charges include "slander, spreading falsehoods, satire and insult to officials and agents."
Hosseini, who has faced prior restrictions from Iran’s security officials, was summoned in June after criticizing President Masoud Pezeshkian's support for Qeshm Free Trade Zone CEO Adel Pighami.
In an X post then, she wrote: "Mr. President, see the result of your support for the corrupt CEO of the Qeshm Free Trade Zone."
She accused Pighami of embezzling public funds and holding back progress at the Qeshm free zone, adding that exposing corruption prompted complaints and threats against her rather than accountability for the issues she rasied.
