The condition was described in a family statement via Crystal Palace as “reversible and treatable”, with the 62-year-old having been discharged from hospital and “settled in new accommodation” to continue his recuperation.
A statement on the ex-England international’s website on Tuesday said he was “looking forward to hopefully a better future” and “very grateful for people’s support” after his condition was made public.
“Kenny Sansom is out of hospital and continuing the early stages of recovery from Wernicke-Korsakoff syndrome, a condition also known as ‘wet brain’,” the statement read.
“Kenny is conscious and able to talk. He is in very good spirits and looking forward to hopefully a better future. He feels in a good place and is very grateful for people’s support.”
The south London-born defender began his career at Crystal Palace before heading to Highbury in 1980.
He wore the captain’s armband as the Gunners won the League Cup in 1987 before leaving the club for Newcastle a year later.
Sansom also played for Queens Park Rangers, Coventry, Everton, Brentford and Watford.
He was part of the England squad that reached the quarter-finals of the 1986 World Cup, making 86 appearances between 1979 and 1988 – making him the Three Lions’ second-most capped full-back after Ashley Cole.
