Jailed former Trump campaign chairman Paul Manafort is suffering from depression, anxiety and “severe gout” while behind bars, his lawyers say in new court filings.

Manafort is being kept in solitary confinement “to ensure his safety” but the conditions “have taken a toll on his physical and mental health,” his attorneys wrote in a document made public Tuesday.

“As just one example, for several months Mr. Manafort has suffered from severe gout, at times confining him to a wheelchair,” they write.

“He also suffers from depression and anxiety and, due to the facility’s visitation regulations, has had very little contact with his family.”

Once known as the “disease of kings” or “rich man’s disease,” gout is a form of arthritis that causes joints to swell — and can be triggered by a diet high in red meats or shellfish, drinking too much booze and sugary soda, as well as crash dieting or dehydration, according to the Arthritis Foundation.

In an October 2018 court appearance, Manafort arrived in a wheelchair with a bandaged right foot, and a source told CNN at the time he was suffering from inflammation related to his diet.

The 69-year-old last year was found guilty of financial fraud and later cut a plea deal in a second case, pleading guilty to two counts of conspiracy and agreeing to cooperate with Special Counsel Robert Mueller’s investigation into Russian interference in the 2016 election.

But Mueller last month accused Manafort of breaking the deal by lying to investigators — and Manafort’s lawyers brought up his health woes in an effort to defend his conduct during their meetings.

During his first trial, Manafort had to move jails after prosecutors said he was getting “VIP” treatment behind bars — staying in a “self-contained living unit” with his own bathroom and shower, and access to a personal laptop and telephone.
