This year is a year of significant steps in the evolution of Brain Impairment. As outlined in the Editorial for Issue 16.1, a new team has been handed the baton from foundation editors Dr Jacinta Douglas and Dr Robyn Tate. The second major development occurring in 2015 is the move from hard copy to an exclusively on-line journal. From the beginning of this year, Brain Impairment will only be available on-line. This development reflects broader moves in academic publishing to an ever increasing footprint within the on-line universe. Many new journals have been launched as purely on-line publications. Established rehabilitation journals that pre-existed the on-line revolution are also joining the trend, adopting hybrid models, with a mix of hard copy and e-articles, all documented in the Issue Contents. Furthermore, most journals have now created e-archives of all past issues, increasing the ease of access for practitioners and scholars alike, and reducing even further, the need for hard copy.

Primary progressive aphasias are rare younger-onset dementias. As the label denotes, these dementias are characterised clinically by marked changes in language skills. Evidence over the years has shown that individuals with primary progressive aphasia experience widespread cognitive and behavioural changes that extend beyond language. This evidence, however, seems to be largely ignored or downplayed. This article proposes that linguistic relativity which induces a cognitive bias may be responsible for this omission; it also indicates that a revision of the current diagnostic criteria may need to be revised.
