- Robin didn't have traditional depression. He had Lewy body dimensia. This was confirmed by his autopsy.
- He had early stages of Parkinson's Disease, with symptoms starting at the end of 2013 until his diagnosis in May of 2014.
- According to The Alzheimer's Association, dimentia with Lewy bodies develop problems with thinking and reasoning, confusion, hallucinations, and visual communication issues.
- The day of his death Susan left for work and Robin was still asleep in another room (they'd been sleeping in seperate rooms due to his Parkinson's symptoms). She asked his assistant to wake him up and the assistant found him dead.
- In July 2014, a month before his death, Susan was in the shower when Robin came into the bathroom and stood by the sink. She looked closer and saw him holding a towel soaked with blood to his head. She asked him what happened and he pointed to the bathroom door. She asked if he hit his head and he nodded. Then he said he "miscalculated."
- In the last week of his life his doctors were planning on checking him into a facility for neurocognitive testing.
