%X Dementia encompasses a variety of underlying conditions among which Alzheimer's disease represents the most common cause and in addition, vascular and Parkinson's disease dementia, dementia with Lewy bodies and frontotemporal lobar degeneration. All the current guidelines specify a two-step procedure for the diagnostics of dementia. The first step entails performing a comprehensive description, diagnosis and confirmation of the syndrome.
