The cause of the rare illness is unknown, but in 30-50 per cent of cases it runs in the family.
Crough is survived by her husband of nearly 30 years, William Condray, their two daughters, Samantha and Alexandra, and one-year-old granddaughter, Evelena.
She was last seen on TV in 2010 when she reunited with some of her Partridge Family co-stars on the Today show.
She said then that she had 'a normal job' working as a manager at an Office Max store.
Crough was just seven when she was picked to join the cast of the sitcom that made stars of David Cassidy, Susan Dey and Danny Bonaduce.

Soon the family was traveling around in a brightly-painted bus and having hits with songs that they originated in their garage.
The show was an instant hit and the first song released as a single and sung by David Cassidy - I Think I Love You - sold five million copies in 1970 and topped the billboard charts.
Reuniting with Cassidy, Bonaduce and Brian Forster on Today, Crough confirmed she never sang for real on the show, joking, 'I was very good at being Milli Vanilli.'
