Jonty Evans has moved to the United Kingdom to aid his rehabilitation with the long-term outlook described as "encouraging" as his condition improves.
Evans suffered a life-threatening fall during the Tattersalls International Horse Trials in June but regained consciousness last month.
Horse Sport Ireland had already confirmed that the 46-year-old suffered a "significant brain injury" after falling from Cooley Rorkes Drift during the cross-country phase of the CIC three-star competition in Meath on 3 June.
Evans received physiotherapy and rehabilitation support from the medical teams at the Connolly Hospital in Dublin for the last number of weeks and was well enough in the last week to move to at a specialist neurology unit in the UK that is "best suited to his needs" at this time.
He said: "I am humbled by all the support I have received and all the help I have been given by the staff at the Beaumont and Connolly Hospitals.
"I would especially like to mention Ciaran and Emily Glynn at Killossery, and my family Maggie Evans, Arthur Griffiths and Hannah Evans for their support.
"I am by no means out of the woods, but intend to keep trying."
Evans’ medical team continue to advise that he remain in a quiet and calm environment, and to keep visitors strictly to a minimum.
