Susan Schneider Williams, the widow of comedy icon Robin Williams, wrote a heartbreaking personal essay entitled, "The terrorist inside my husband's brain." In it, she spoke about the debilitating neurological disease that doctors believe led to her husband's suicide in 2014.

After his death, doctors concluded that Williams was suffering from Lewy body disease (LBD), a kind of dementia that affects cognitive abilities due to the degeneration of the brain.

LBD made things like remembering lines, recalling memories, and functioning day to day extremely difficult. Schneider Williams remembers her husband having a severe panic attack while filming Night at the Museum 3.
