#Lithium reduced suicidality 49% in this new analysis of 13 randomized controlled trials (Caveat: Suicide was not the primary outcome in these studies): https://lnkd.in/eK6dg5qB Bottom Line: Don't avoid lithium to prevent suicidal overdose; the data suggests the opposite. NEW: Carlat #Psychiatry News, with in depth coverage of the daily studies posted on this feed: https://lnkd.in/es9s3KdU The April episode features #MDMA therapy, #lithium, #PTSD, #bipolar, #clozapine, #schizophrenia, #ECT, and a circadian therapy for #depression
I don’t use lithium as a primary mood stabilizer unless a patient is already doing so and likes it (so never), but 300mg QHS really shallows out depression and usually significantly reduces or even eliminates suicidal ideation. It also contributes significantly to improved sleep.
Lithium is not binary. Meaning that the benefits for mental AND physical health exist on a spectrum. From the micro in water/soil to low dose lithium (150mg-450mg LiCO3) to dosing above 600mg leading to a level of 0.6. And yet, it’s last on the list in psychiatry. An indictment of us on its own.
Findings from a long-term (10-year) observations of patients with bipolar I disorder found a significantly lower (5.2-fold) occurrence of suicide attempts and suicidal behavior in lithium-treated patients. This unique anti- suicidal effect is not seen with other mood stabilizers . Lithium also changes the longitudinal course of illness: It helps to stabilize mood swings and is particularly effective in preventing relapses of mania and depression.
Notably, just a couple of years ago, this meta-analysis didn't identify a significant protective effect of lithium against suicide in randomized controlled trials. They arrived at precisely the same odds ratio, albeit with a broad confidence interval. The reason lies in the trials' low suicide rates – 0.2% with lithium and 0.4% in the control group, which translates to an impressive OR but minimal absolute risk reduction. The limitation stems from the fact that these short-term trials with highly selected participants may not accurately reflect real-world cohorts. https://pubmed.ncbi.nlm.nih.gov/36111461/
I have seen Lithium work wonders for four decades.
Thank you, Dr Aiken! Such an important meta-analysis to remain mindful of (regardless of the primary outcome) in the wake of novel agents lacking this long h/o robust data. Unlike anticonvulsant mood-stabilizers, lithium doesn't interfere with ketamine's rapid reversal of acute SI, and the pairing can be truly life saving.
Crazy that all the included trials were not statistically significant yet the summary statistic is. Quite an extreme example of the advantage of meta when primary studies are underpowered but it would be nice to at least see a couple primary studies significant on their own.
Agreed. Let’s focus on the prevention therapies for tardive dyskinesia to reduce patient objections.

8moThank you as always Chris. It would be interesting to look at cardiovascular mortality in mood disorders. I haven’t seen much in terms of any studies along these lines. The death ratio of CVD to Suicide/ accidents is 2:1. Lithium is detrimental to cardiac mitochondria, so in theory may increase the risk, although, untreated, the disease and its sequelae (alcohol and stress) may increase CVD mortality anyway.
