Robin Williams' wife Susan Schneider had said that the acclaimed actor and comedian was suffering from the early stages of Parkinson's disease at the time of his death.
Schneider said that her "sober" husband was "not ready" to reveal about the degenerative neurological disorder publicly, BBC reported.
The 'Jumanji' star's spouse further added that he was suffering from anxiety and depression and had offered joy and happiness to those fighting personal battles.
Schneider continued that it was their hope in the wake of Williams' death, others would find the strength to seek the care and support they needed to treat whatever battles they were facing in order to feel less afraid.
It was earlier revealed that Williams, who was found dead in his room, is said to have died of asphyxia due to hanging.
