Recent literature on the relationships among dementia, depression, and social support was reviewed, with particular emphasis on the diagnostic differentiation of dementia and depression, and the role of these three entities in elderly individuals with cognitive impairment. Dementia-like symptoms arising in depression and the coexistence of dementia and depression are discussed. Research is necessary to determine more objective criteria for depression and dementia, to provide cognitive and psychiatric testing for elderly individuals, to clarify the diagnostic or prognostic value of the term pseudodementia, and to further elucidate relationships between depression, dementia, and social support.

The Star Trek franchise currently includes five spin-off series and 13 motion pictures. Star Trek's central theme is the utopian future of mankind, but the series does not disregard issues that were socially relevant for its time of production. Therefore, Star Trek has functioned as a representation of history throughout its 50-year lifespan. This paper conducts a comparative analysis of fictional representations of psychological disorders and corresponding treatments to retrace the cultural changes in the portrayal and treatment of psychological disorders from the 1960s to the turn of the millennium. Video material produced between 1966 and 1999 was analysed with a focus on psychological disorders and coded according to the ICD-10. The results of the quantitative analysis indicate that the different Star Trek series demonstrate similar patterns of percentage distributions for psychological disorders. The qualitative analysis shows that psychological disorders were portrayed and treated in an increasingly realistic fashion. Changes in society's attitude towards psychological disorders can be comprehensively illustrated through Star Trek episodes produced through 1999. Psychological phenomena are increasingly destigmatized, and the necessity of treatment has not been disregarded.
