Good morning!
Ok. Untill (and during) the Sydney Olympics and Paralympics, Profile 39 was a category itself withing the para sport movment. Intellectual impairment
However, following the Spanish basketball scandal at Sydney 2000, it was removed.

The IPC reation
The IPC announced that, due to serious difficulties in determining the eligibility of athletes, it was suspending all official sporting activities involving an intellectual disability.[9] The IPC attempted to develop a revised system for testing for intellectual disabilities but announced on 1 February 2003 that all events involving learning difficulties would be abandoned for the 2004 Summer Paralympics in Athens.[8][10]
Following an anti-corruption drive, the International Sports Federation for Persons with an Intellectual Disability (INAS-FID) lobbied to have these athletes reinstated. Beginning in 2004, athletes with an intellectual disability began to be re-integrated into Paralympic sport competitions, although they remain excluded from the Paralympic Games. [1] The IPC has stated that it will re-evaluate their participation following the Beijing 2008 Paralympic Games.[
So,in the past year or so I received an email from IPC re reintroduction of profile 39 athletes

As of yet equestrianism has not been included. However, from the FEI point of view it would be seriously worth noting that 33 countries competed in equestrian at the recent Special Olympics in Greece. (Australia did NOT field an equestrian team which is in itself a disgrace!!)
Think of how the extra countries would benefit towards the globalisation of paraequestrian!!
