Ketamine for Treating Depression
Dr. Manevitz commented for a WebMD article on using Ketamine as a treatment for depression.
“Ketamine is not a miracle drug at all,” Manevitz says. “It may momentarily take them away from that catastrophic place they’re in with depression, but you’re not addressing the rest of the patient. It’s a complex issue to treat psychiatric issues, and you have to treat the whole patient.”
Teach Your Children to Be Grateful
Children raised to be happy, well-adjusted adults are instilled by their parents with a strong sense of gratitude. 
A Saturday Essay in The Wall Street Journal cites research indicating that children raised to appreciate the actions and feelings of others are more attentive in school, less aggressive, and have fewer symptoms of depression. When these children become adults, they are more likely to handle setbacks positively and exhibit better mental health.
