Vitamin B6 Plus Lithium Helps Ease Mania Symptoms in Patients With Bipolar Disorder

Daily vitamin B6 (40mg/day), but not B1 (100mg/day), as an adjunctive therapy to lithium was associated with the improvement of mood symptoms in hospitalized patients with bipolar disorder experiencing a manic episode, according to a study published in the Journal of Affective Disorders 2024; 345 103-111: Zandifar et al.

Cannabis and Cannabinoids Don’t Work for Pain or Posttraumatic Stress Disorder

Aaron S. Wolfgang, MD and Charles W. Hoge, MD reviewed data on cannabis in JAMA Psychiatry and found that there were big placebo effects and no evidence for effectiveness of cannabis in military personal.

This negative data, along will all the liability of cannabis potentially causing or triggering psychosis, bipolar disorder, and schizophrenia (as well as possibly contributing to cognitive dysfunction, worsening anxiety and depression in patients with mood disorders) makes the use of pot for medical purposes an entirely foolhardy proposition, as well as a waste of money.

Legalization of pot has helped people avoid jail but precipitated a rash of use and over use.

So the bottom line from this editor is: Get Your Priorities Straight. Cannabis and Cannabinoids Don’t Work for Pain or Posttraumatic Stress Disorder and they Worsen Most Everything Else. Save your Money and Do Something Nice for Yourself and Others Instead.

More Data that Long Term Lithium Treatment Does NOT CAUSE RENAL TOXICITY (more than those on valproate).

In a recent meeting, Mark Weiser of Sheba Medical Center analysed data from “from the Clalit Health Services (CHS) database, the largest provider of health insurance in Israel, n=4.8 million, representing over 50% of the Israeli population. This study examined lithium use between the years 2000 and 2022, focusing on its impact on kidney and thyroid function…(and) compared all patients receiving lithium (n=19,433) to all patients receiving valproic acid (n=44,524). There was no different in the life-time rates of dialysis between patients treated with lithium and patients treated with valproic acid (1.03% vs 0.99%, p = 0.683). A lifetime diagnosis of hypothyroidism was more common in patients receiving lithium (21.84%) in comparison to patients treated with valproic acid (8.83%, p = <0.0001). Conclusions: In this large population study, treatment with lithium was not associated with decreased kidney function but was associated with a clinical diagnosis of hypothyroidism. These factors should be taken into account when considering treatment with lithium.”

Editors Note: In patients on lithium, overtime there are small decreases in estimated glomerular filtration rate (eGFR), but these do not differ from those seen in physiological age adjusted eGFR in the general population. These data are convergent with the large national studies of Kessing et al in Denmark and indicate that the long-held view of lithium causing undo renal toxicity are not accurate and are based on inappropriate suppositions without an adequate control group. They found more end-stage renal dysfunction in bipolar patients treated with anticonvulsants than with lithium.

THERE IS A GRAVE UNDERUTILIZATION OF LITHIUM DUE IN LARGE PART TO THE FALSE ASSUMPTION THAT IT CAUSES EXCESS RENAL TOXICITY. PATIENTS AND CLINICIANS SHOULD BE MADE AWARE OF THE NEW DATA THAT THIS IS LIKELY RELATED TO POOR METHODOLOGY AND BEGIN TO MORE FREQUENTLY THINK ABOUT USING LITHIUM — UNEQUIVOCALLY THE BEST DRUG FOR THE TREATMENT OF BIPOLAR DISORDER. LITHIUM ALSO HAS THE BEST DATA FOR REDUCING EPISODES OF BOTH DEPRESSION AND MANIA AND FOR HAVING POSITIVE EFFECTS IN PREVENTING SUICIDE. USING LITHIUM MORE OFTEN WILL UNDOUBTEDLY MARKEDLY IMPROVE PATIENTS WELL BEING AND SURVIVAL. THIS EDITOR BELIEVES THAT GIVEN LITHIUM’S MULTIFACETED ROLE IN AMELIORATING ALMOST ALL ASPECTS OF THE COURSE OF BIPOLAR DISORDER, IT SHOULD BE CONSIDERED A “DISEASE MODIFYING DRUG.” THERE ARE MULTIPLE DISEASE MODIFYING DRUGS FOR TREATMENT OF MULTIPLE SCLEROSIS, AND EXPERTS IN THAT FIELD BELIEVE THAT DISEASE MODIFYING SHOULD BE STARTED AS EARLY AS POSSIBLE AFTER FIRST DIAGNOSIS. A SIMILAR CONCLUSION WOULD NOW APPEAR APPROPRIATE FOR LITHIUM.

Of note is the other widely held reason for not using lithium more often is that it causes hypothyroidism. While this is clearly correct based on the Weiser study and many other data, patients should be aware that this well-known condition is readily correctable with thyroid hormone replacement and does not produce an undo burden on patients.

Since lithium has many other assets including: increasing hippocampal volume; protecting memory; and increasing the length of telomeres (critical to sustaining good medical and psychiatric health), its wider use in bipolar disorder should be a no brainer. However, it is likely (like most revisions in medical lore) to take 10 years or more before this re-evaluation of lithium has an impact on conventional treatment decisions, so physicians should make very active and conscious decisions about changing their routine choices of treatment for each patient with bipolar disorder.

Changes in brain structure in remitted bipolar patients

Macoveanu et al reported in the Journal of Affective Disorders (2023) that compared to controls that remitted bipolar patients had “a decline in total white matter volume over time and they had a larger amygdala volume, both at baseline and at follow-up time. Patients further showed lower cognitive performance at both times of investigation with no significant change over time….Cognitive impairment and amygdala enlargement may represent stable markers of BD early in the course of illness, whereas subtle white matter decline may result from illness progression.”

Assets of Exercise

Highlights from the International Society for Bipolar Disorders Conference Posters and Presentations, Chicago, June 22-25, 2023

Ben Goldstein of the University of Toronto gave a plenary talk on the benefits of exercise.

He found poor aerobic fitness in 19 of 20 young bipolar patients. They had low cerebral blood flow in proportion to the severity of their exhaustion after exercise. He noted the importance of stressing an endpoint of fitness for exercise rather than weight loss. Using an exercise coach and running with family and friends was helpful in motivating patients for consistent exercise.

High Response Rate to Psilocybin in Bipolar II Depression

Highlights from the International Society for Bipolar Disorders Conference Posters and Presentations, Chicago, June 22-25, 2023

Scott Aaronson gave 15 medication-free BP II patients (off all medications) 25mg of psilocybin with extensive therapeutic support. He saw rapid onset and persistent AD effects, such that at the end of 12 weeks 12 of the 15 patients were still in remission. Quality of life increased and suicidal ideation decreased. He indicated that others found that serum BDNF increased 1000 fold greater than baseline.

Metabolic Changes in Brain of Bipolar at Autopsy

Highlights from the International Society for Bipolar Disorders Conference Posters and Presentations, Chicago, June 22-25, 2023

Graeme Preston reported on the brain of autopsied bipolar patients having increases aspartate and citrulline, while those with unipolar depression had decreases in the TCA cycle.

He saw increases in acetyl carnitine in manic bipolar patients versus bipolar depressed patients, which is of interest in relationship to the putative antidepressant effects of acetyl-L-carnitine in animal models of depression and in humans.

Preliminary data on ketogenic diet

Highlights from the International Society for Bipolar Disorders Conference Posters and Presentations, Chicago, June 22-25, 2023

Georgia Ede gave a talk on the first results of 12 bipolar patients using a ketogenic diet (composed of 75% fat; 5% carbohydrates; 20% protein) as a adjunct to about 5 medications that were insufficiently effective. She saw improvement by week 3, 58% remitted, and some lost weight. She indicated that some could revert to a regular diet after the improvement achieved by children, but not in adults.

Sebari Sethi talked about 26 of 27 bipolar patients who achieved 1.3 mmole/L ketones and lost weight and showed increases in glutamate in brain measured by Glx and decreases of 11.2% in the ACC

The Need for Psychotherapy for Bipolar Disorder

Highlights from the International Society for Bipolar Disorders Conference Posters and Presentations, Chicago, June 22-25, 2023

Greg Murray gave a talk on effectiveness of multiple types of psychotherapy for bipolar disorder and suggests that the choice be designed for each individual.

He describes 10 core elements of each type of therapy. These included dealing with:

  • 1. Knowledge, acceptance, and adherence
  • 2. The presence of anxiety in some 90% of patients
  • 3. Suicidality and crisis management
  • 4. Skills: monitoring, relapse prevention, life time events, recognition of early symptoms
  • 5. Identity, cognitive restructuring, dealing with stigma, train action and achievement, confronting perfectionism, CBT
  • 6. Sleep and circadian rhythms
  • 7. Trauma, child adversity, PTSD
  • 8. Emotion regulation
  • 9. Relationships: social, family, occupational roles (family or group)
  • 10. Substance use and avoidance, access, motivational interviewing, impulsivity

Pediatric Bipolar Disorder is Associated with Neurocognitive Deficits

Highlights from the International Society for Bipolar Disorders Conference Posters and Presentations, Chicago, June 22-25, 2023

Maria Paula Maziero of The University of Texas Health Science Center At Houston reported that while euthymic youths with BD (bipolar disorder) exhibited significant dysfunction in working memory (WM), verbal learning, and memory domains, fluctuation between the mood states affected the type of cognitive dysfunction. They concluded: “Pediatric bipolar disorder patients have marked cognitive dysfunction involving multiple domains, especially executive measures. The severity of mood symptoms influences cognitive performance, but even euthymic persons perform lower than matched controls.
