Which got me pondering as to how the Labour Party leadership candidates are bearing up as we enter the thirteenth week of campaigning. With the DSM as my guide, I think I may have noticed a condition or five that point towards everyone needing to take a few days off:
SERRACUMMUSICUS INSILIOMANIA 
an irresistible compulsion to jump on bandwagons
HYPERBOREAN TOURETTE'S
inability to stop mentioning one's regional provenance
PEDAGOGICAL INTERROGATIVE APHASIA
 a speech impediment presenting as tongue paralysis 
when asked a question about education
HEALEY'S PARANOIA
unavoidable anxiety experienced by those 
diagnosed as the frontrunner
(see also Heseltine Syndrome and Acute Portilloism)
diagnosed as the frontrunner
(see also Heseltine Syndrome and Acute Portilloism)
CLP-TYPE MICRONUMEROPHOBIA
severe aversion to smaller than expected returns 
from the local party nominations
The good news is that most of these are reckoned to be seasonal disorders and that everyone should be cured by the 25th September.
