There is the Law Project N. 61 (2017) which is under consideration and establishes that people with Alzheimer’s disease will receive income tax waivers (Brazilian Federal Congress, 2017). While this matter has not been decided in court, many people living with Alzheimer’s disease have pleaded for the tax waiver in court and have obtained it.
