In the public health system (SUS) diagnosis would typically follow a pathway where a case would initially be identified by a GP at a Primary Care Unit and would be referred to a specialist for confirmation (usually neurologist or geriatrician). Yet in the public health system, people may also be diagnosed at other levels of care when people access them for other reasons, and clinicians may suspect of dementia (A&E, general hospital, other specialities outpatient care). In the private sector, the typical pathway is that families/patients who are suspecting that something is wrong, may take the patient directly to a specialist, usually a neurologist. As in the public services, clinicians from the private sector may identify cases also in other levels of care (hospital outpatient care).  It is important to remember that rates of underdiagnosis are high in Brazil.
