The study is designed to inquire whether the presence of periodontitis and different periodontopathogenic bacterial strains are associated with dementia diagnosis and with the degree of cognitive impairment in participants evaluated at a Memory clinic (Minnesmottagning). Specifically, by analyzing cerebrospinal fluid, the investigators intend to clarify whether the alleged mechanisms for Porphyromonas gingivalis in the aetiology of Alzheimer disease (AD) are supported in a Swedish population and whether they are specific for Porphyromonas gingivalis (as compared to other periodontopathogenic bacteria) and Alzheimer type dementia (as compared to other etiological dementia types), respectively.
