I saw an article with part of a story about his daughter, and poked around to find the rest of the story:

(December 2008) Adopted daughter, Catherine Falk, files for conservatorship, explaining that Falk has been suffering from Alzheimer's Disease and, at 81, he no longer recognizes anyone. Later sworn statements from the Falk family, family friends and associates report Catherine has been long-estranged from her father and would not handle his affairs in his best interest.

(January 2009) Shera Danese, Falk's wife of 32 years, files paperwork with the court, including sworn statements from longtime CPA, attorney, friends & family members, stating she is already attending to Falk's affairs, Falk named her as his guardian when first diagnosed with the disease, and long-estranged adopted daughter's attempt to gain conservatorship and control of his affairs is NOT in Falk's best interests.

(May 2009) Shera Danese, his wife, is awarded conservatorship of his affairs.

Sad times in a family. The UK article only gave the daughter's story that she wanted to protect her father, it didn't explore why the wife couldn't do it. Perhaps the daughter sent out promotional materials to support her case?
