“This summer has been exceedingly difficult,” Mikhaila Peterson said in a YouTube post this week, describing the 62-year-old Canadian author’s prolonged health crisis and calling the past few months “terrifying” for their family.

Mikhaila said her father had been treated in the intensive care unit after he was diagnosed with pneumonia and sepsis.

She said that her dad’s latest health issues came after he had dealt with a “host of neurological issues this summer that we believe stem from SERS, which is chronic inflammatory response syndrome, due to decades of mold exposure.”

She said the condition triggered a series of “neurological symptoms” that worsened after Peterson cleaned out his late father’s basement earlier this year.

“We don’t have a better explanation for his neurological symptoms at the moment other than spiritual attacks,” she said.

The update marks the first detailed account of Peterson’s condition since his daughter announced in August that he was taking “time off of everything.”

“He’s been suffering for the last number of years with unexplainable neuropathy and weakness, amongst other symptoms,” she said.

“After almost a month in the ICU, he’s been moved out to a less urgent floor. Praise God for that.”

Mikhaila said her father is now improving, but his recovery remains uncertain.

“We’re still in the midst of this but now we’re seeing improvements daily,” she said.

“The timeline for his full recovery is hard to tell at the moment.”

She added that Peterson’s treatment is complicated because “he can’t take most medications without suffering from severe paradoxical reactions, which limits treatment options.”

Mikhaila, 32, described a series of personal emergencies that struck the family this summer, including a medical scare involving her newborn daughter.

She added that Peterson’s treatment is complicated because “he can’t take most medications without suffering from severe paradoxical reactions, which limits treatment options.”

“In August, the day Dad was brought to a hospital by ambulance, my newborn Audrey was also brought to a hospital by ambulance within hours of each other,” she said.

The baby, who was previously treated for pulmonary hypertension, has since stabilized.

“Every single day this summer and now fall has been like watching a movie,” she said, pausing through tears.

“I miss my dad. My brother misses his dad. My mom misses her best friend and husband.”

Mikhaila, who co-hosts her father’s Daily Wire program “Answer the Call,” said Peterson’s hospitalization followed weeks of worsening health linked to his immune system disorder.

She said the illness has been “heartbreaking and brutal” but stressed that her father’s condition is improving.

“He’s hopefully recovering,” she said. “He’s out of the ICU so that’s the main thing. … Praise God for that.”
