Brian Wilson's family have sought a conservatorship

The 81-year-old musician's loved ones are concerned for the welfare of the 'Good Vibrations' hitmaker after his wife, Melinda Wilson, died aged 77 last month, because he suffers from what court documents described as a "major neurocognitive disorder (such as dementia) and want to have family representatives formally appointed to make decisions on his behalf.

Brian's family told People magazine in a statement: “Following the passing of Brian’s beloved wife Melinda, after careful consideration and consultation among Brian, his seven children, Gloria Ramos and Brian’s doctors (and consistent with family processes put in place by Brian and Melinda), we are confirming that longtime Wilson family representatives LeeAnn Hard and Jean Sievers will serve as Brian’s co-conservators of the person.

“This decision was made to ensure that there will be no extreme changes to the household and Brian and the children living at home will be taken care of and remain in the home where they are cared for by Gloria Ramos and the wonderful team at the house who have been in place for many years helping take care of the family."

They added the 'I Get Around' singer can still "enjoy all of his family and friends and continue to work on current projects as well as participate in any activities he chooses.”

Court documents obtained by People noted Brian is “unable to properly provide for his or her personal needs for physical health, food, clothing, or shelter" and he had previously relied on Melinda to attend to his "daily living needs".

They also stated the singer - who had adopted children Dakota, Daria, Delanie, Dylan and Dash with Melinda, as well as Carnie and Wendy from his first marriage - had an “Advance Health Care Directive” naming Melinda the “agent” for his health care but there was no successor listed in the event she was unable to carry out the duty, so they asked a court to appoint a conservator.

LeeAnn and Jean were proposed because they "have had a close relationship with Mr. and Mrs. Wilson for many years, and Mr. Wilson trusts them", with the former also Brian's “agent under his power of attorney.”

As co-conservators, the pair plan to “ensure that all of Mr. Wilson's daily living needs are [satisfied] and he has the best possible care while remaining in his home."

The petition stressed the 'Surfin' USA' hitmaker wouldn't be able to attend any court hearing.

His doctor wrote: "He is easily distracted, often even when aware of surroundings, and its purpose.

“Often makes spontaneous irrelevant or incoherent utterances. Has very short attention span and while unintentionally disruptive, is frequently unable to maintain decorum appropriate to the situation.

The medica also noted his famous patient is taking medication to slow “progression of illness.”

A court hearing is scheduled for 26 April.
