Public health services (SUS) are free of charge and include medication (anticholinesterases). Those using the private sector may have health insurance which can be paid by employers or privately by themselves. It is also usual, for those who can afford it, to go directly to a well-known specialist for diagnosis and to pay the doctor directly for the consultation (usually very expensive). Sometimes, people do that in the beginning but end up in the public services as they cannot afford subsequent consultations or exams.
