“Sleep researchers are also looking at the potential of certain facets of sleep to treat post traumatic stress disorder. One study suggests that sleeping within 24 hours of a traumatic experience will make those memories less distressing in the subsequent days. For people with anxiety, sleep therapy might help with reminding people that they’ve eliminated their fear.”

But while people with typical cognitive patterns need sleep to recover from intense experiences, it may be different for those with depression.
“Wake therapy, where people are deliberately deprived of sleep, is spreading as a method of treating depression. It doesn’t work in all cases. But it may be that it jolts the circadian system, which is prone to sluggishness in people with depression.”
“Sleeplessness in some cases may have a protective effect. Often following intense trauma, “the natural biological response in those conditions is that we have insomnia”. This may be an appropriate response to an unusual situation.”
So sometimes it can actually be a good thing that REM sleep deprivation harms the brain’s ability to consolidate emotional memories. “There’s good evidence that people who have longer REM sleep tend to be more depressed,”
“Why does sleeplessness help the emotional state of some people with depression and trauma, but not others? New work by suggests that the difference may come down to genetics. A particular gene, called the brain-derived neurotrophic factor (BDNF) gene, appears key to memory consolidation during sleep.”
“People with a specific gene mutation are vulnerable to the frequent, unhelpful circling of negative memories during sleep – for them, it could be helpful to go to sleep early and get up very early.”
And the new research suggests that people who have a specific mutation of the BDNF gene are vulnerable to the frequent, unhelpful circling of negative memories during sleep. For them, it could be helpful to go to sleep early and get up very early to minimise the amount of REM sleep.

This is such interesting info about sleep, memory, and depression. I’m not sure how to translate it to my ongoing insomniac problems as I don’t actually suffer depression but seem to have PTSD. I’ll have to sleep on this and let you know in the morning.
I love the cartoons. The one of the sleeping cat looks like a rabbi channeling psalms – could be a good thing.

Shari,
The sleep research is really fascinating – given that most “animals” spend such a tremendous amount of time in sleep (insomniacs withstanding). My professional experience was that people on the “anxiety spectrum” had difficulty sleeping and those on the “depression spectrum” slept too much. Who knows what comes first the chicken peeping or the egg sleeping – probably all inter-related.
The sleeping cat is Jewish, no doubt.
