Groundbreaking model and restaurant mogul B. Smith is suffering from Alzheimer’s Disease, media outlets reported June 5.

Barbara Smith, 64, detailed her condition in an interview set to air on “CBS Sunday Morning” on June 8. In the emotional interview, Smith struggles to name the date of the interview, the month, or the year.

“Things like that make me very sad,” Smith said, according to the New York Daily News.

Smith told CBS News she was first diagnosed four years ago when she began noticing symptoms such as repeating statements or not answering questions.

Smith opened her first New York restaurant in 1986 after a career in modelling that saw her become one of the first African-American models on the cover of “Mademoiselle” magazine. Two more restaurants, several books, and a TV show followed, according to CBS, leading some to dub her “the Black Martha Stewart.”
