Erika Jayne's husband Thomas Girardi has been diagnosed with late onset Alzheimer's disease amid the couple's divorce and a host of lawsuits currently against him.

In addition to being married to the "Real Housewives of Beverly Hills" star, Girardi, 81, is a well-known attorney in California. Although online records viewed by Fox News show he is currently "not eligible to practice law" in the state, as of Tuesday, March 9.

A declaration filed by Girardi's physician on Wednesday in his ongoing conservatorship case states that the reality TV star's estranged husband currently "suffers Alzheimer's disease with late onset" in addition to dementia.

The doctor notes that Girardi is unable to attend court hearings in his legal matters because his "dementia impairs his ability to understand the hearing."

Girardi also is suffering from "emotional distress," the doctor notes, which is "directly related to his dementia and exacerbated by his confusion."

In February, a judge named Girardi's brother, Robert Girardi, his conservatorship following claims he was suffering from memory loss.
