TED: Laurel Braitman: Depressed dogs, cats with OCD — what animal madness means for us humans - Laurel Braitman (2014)

Summary: Behind those funny animal videos, sometimes, are oddly human-like problems. Laurel Braitman studies non-human animals who exhibit signs of mental health issues -- from compulsive bears to self-destructive rats to monkeys with unlikely friends. Braitman asks what we as humans can learn from watching animals cope with depression, sadness and other all-too-human problems.
