Robin Williams, who died聽Monday聽in what police are calling a suicide, had a long history of depression and addiction, according to those nearest the comedian.

Now, as friends and fans alike struggle to understand what drove the 63-year-old star to take his own life, many in the field of mental health say the discussion has opened an important window on a problem that is often聽under-treated due to fear of cultural stigma.

鈥淒epression is a growing problem,鈥� says聽Carla Sofka, professor of social work at Siena College in Loudonville, N.Y. The Centers for Disease Control recently identified depression as a serious and growing problem, while the US military has sounded an alarm at the increasing incidents of depression and suicide聽by both active duty and veteran聽personnel.

鈥淭his discussion聽around Robin gives people permission to talk about聽something that they otherwise might be too afraid to discuss,鈥� Professor Sofka says.

Twitter, Facebook, and other social media sites are awash in such discussions, points out Sofka, who studies the relationship between celebrity and mental health issues.聽

She notes that both celebrities and private individuals are opening up about their struggles with depression and聽suicidal thoughts. 鈥淭here is this cultural moment in which it聽is suddenly safe to talk about these things,鈥� she says, even celebrities with more to lose in terms聽of public reputation.

鈥淭witter has been very active including several conversations about the crippling nature of depression,鈥� she says. An example of the celebrity dialogue emerging in social media was the Twitter feed from Dave Foley of 鈥淜ids in the Hall鈥� fame and聽more recently a guest role on 鈥淗ot in Cleveland,鈥澛爄llustrating that success does not always bring happiness.

Often, however, the individual most at risk is least likely to reach out in ways that might help, points out Sheila Hunt, director of community education for Pacific Grove Hospital, a treatment facility in Riverside, Calif.聽

鈥淭hey are afraid of losing a job, or what friends might think,鈥� she says, so they ignore or聽hide it from those close to them.

鈥淢any people will go to a doctor for a physical聽sickness or other medical issue, but they are much less likely to seek treatment for mental health issues,鈥� she says.

鈥淭hat鈥檚 why we need more education about the聽warning signs for people around the one that might be in trouble,鈥� she notes, pointing to everyone from friends and family to teachers and聽ministers. Behavior to watch for includes sudden changes such as giving away prized possessions to friends or talk of 鈥渏ust wanting to go to sleep and never wake up,鈥� says Ms. Hunt.

Such detection can be more difficult with an individual such as Williams, who has聽wrestled the twin demons of depression and聽addiction throughout his career.

Many聽assumed he had a handle on the challenges he faced, particularly as he had just recently returned聽from a stay in a Minnesota rehab clinic. Nonetheless, some friends suggest they began to see signs of聽new challenges to his mental health. Friends who saw聽Williams in the months leading up to the suicide say they noted a change in his behavior, particularly after his CBS sitcom, 鈥淭he Crazy Ones,鈥� was canceled in May.

In the聽Los Angeles Times聽Wednesday,聽longtime friend and fellow comic聽Steven Pearl said he鈥檇 seen聽Williams during the summer and was worried.聽

"You could just tell something was off," Mr. Pearl said. "He seemed detached. It's hard to explain. He didn't seem like his usual self. My fianc茅e and I were like, 'Is he OK?' I didn't know it would get this dark."

Indeed, publicly at least, Williams appeared to have his challenges under control. According to聽a publicist statement reported in the L.A. Times,聽Williams checked himself into the rehab facility to "fine-tune and focus on his continued commitment" to his sobriety.
