That law applies to mental conditions because of the distress saying you won't get better can cause. Not to all conditions. It also doesn't say you have to tell them they will get better like you said. Notice this thread is about brain diseases. I think you added that which is understandable with the stress we are all under. You just can't say you won't get better.
The Tennessee Supreme Court in three cases in 2024 said. "From expert testimony from the Neurologists involved in these cases... The court is of the opinion every Vulnerable Person (Brain Capacity) has two underlying emotions and thoughts"....." 1. The hope they will get better and 2. Fear". These were cases of Abuse of Vulnerable Adults, under the Tennessee Vulnerable Adult Protection Act and the Court said. "Any person can tell if they have committed Abuse of a Vulnerable Adult if what they do or say reduces that Vulnerable adults Hope or if what they do or say increases that Vulnerable adults fear". So in my case before I remarried my wife so I could care for her, she lost her Drivers License and she wanted to talk to her son about taking the test again. After about 5 minutes he yelled Mom I'm tired of talking about this. You're not going to get better!!! That destroyed her hope and caused tremendous fear. It was a Class D Felony. He didn't care about her feelings. He just didn't want to fool with her. Actually her Neurologist notes a month earlier said "She seems to be getting better" but her son wouldn't dare tell her that! He always would say... "If you don't stop "Acting Up", I'm going to put you in that place you don't want to go" ( Assisted Living). He is an Orthopedic Physicians Assistant, not uneducated. When she fell, and had 2 fractured ribs and 2 displaced ribs and a Rotator Cuff tear he wouldn't even take her for Medical treatment. By the way "Acting up" was seeing and talking to me. After we remarried we discovered he emptied her bank account and used part of her monthly income to pay his Chase Credit Card. She asked for an accounting 3 times and he said "don't worry mom you've got plenty of money". Her daughter who works in a nursing home "Borrowed" my wife's nice Volvo xc60 SUV and wouldn't return it after a year and my wife asking for it 8 times. So me showing back up was going to blow their schemes of taking all their mother's assets. People, even family write OUR loved ones off and even do things like this. They've punished my wife for remarrying me now by cutting off all contact with the grandchildren she adores.
So I've taken 2 years becoming as much of an expert for my wife's care as I can as a lawyer and absolutely an expert on Vulnerable Adult Persons Protection Act. On the Drivers License; she may never get it back but I got her Volvo back and I take her after church or on Saturdays to vacant school or industrial parking lots and she drives around as long as she likes. It tickles her to death. There are countless things we can do at any stage to lift them up, make them feel as normal as possible, give them joy, though it may be small to us. I cherish every normal and abnormal minute with her. Even the ones that drive me crazy because when I didn't have her I felt crazier. Every time she walks by me I say I love you. She gets so tired of that; LOL.
I didn't mean to come across harsh in the beginning here but I just wanted you to be clear that you are correct about what you said and what the supreme Court said wasn't that we should instill false hope. We just shouldn't dash the hopes the person may have, or increase the fears they have , even secretly from us. This is hard yes, but it's harder on her. God bless every minute you have left!!!
