According to her doctor, Brandão, who starred in the Netflix series Sintonia, experienced 13 cardiac arrests between Wednesday and Thursday.

As of Monday, Brandão’s cause of death remained a mystery. The doctors still haven’t said what really happened to my daughter and what killed her,” Brandão’s mother, Thays Brandão, told Brazilian news outlet G1.

Millena Brandão has been experiencing headaches, leg discomfort, fatigue, appetite loss, and fainting since April 24.

She went to two state-run hospitals in São Paulo and a city urgent care centre during that time.

Before further testing showed a brain tumour, doctors thought the young model had dengue fever.

Millena Brandão made her acting debut in October 2023 on SBT [Brazilian Television System] and had appeared “A infância de Romeu e Julieta” [Romeo and Juliet’s Childhood] and “A Caverna Encantada [The Enchanted Cave].”

Another mother of a two-year-old daughter, Thays Brandão, expressed doubts about the treatment her daughter received from the doctors.

On April 24, Millena Brandão was seen by a doctor at the state-run Pedreira General Hospital, who diagnosed her with a headache and informed the distraught mother that her kid had “dengue fever.”

“But he didn’t do any tests. He told us to take her back home and give her dipyrone,” Thays said.

Millena Brandão left a modelling event on April 26 because she was experiencing leg pain. She was sent to Pedreira General Hospital, but testing showed no problems, so her mother advised her to stay at home and relax.

The family had intended to attend mass at a nearby church on April 28, but Millena Brandão informed her parents that she was feeling sleepy, had headaches, and had no appetite, so they decided to stay home instead.

After eating dinner at home on April 29, Millena Brandão passed out in the restroom.

After her parents brought her to the Maria Antonieta Urgent Care Facility, tests revealed that she had “a urinary tract infection” and was prescribed medication, although the results were negative for COVID-19, H1N1, and dengue fever.

“She arrived with her unconscious in my husband’s arms. Then, she opened her eyes and regained consciousness,” Thays Brandão recalled.
