Risk of Attempted or Completed Suicide in Borderline Personality Disorder: Reduced with ADHD meds; Increased with Benzodiazepines
Johannes Lieslehto et al 2023 reported in JAMA New. Open on the comparative effectiveness in 22,601 individuals with BPD that “ADHD medication was the only pharmacological treatment associated with reduced risk of suicidal behavior among patients with BPD. Conversely, the findings suggest that benzodiazepines should be used with care among patients with BPD due to their association with increased risk of suicide.” Mood stabilizers had no effect while antipsychotics minimally and antidepressants moderately increased risk of suicide attempts or completed suicide.
Young Men at Highest Schizophrenia Risk From Cannabis Abuse
Roughly 15% of schizophrenia cases among young males may be preventable by avoiding cannabis use disorder (CUD). Not only does cannabis abuse markedly increase the risk of schizophrenia, its use has transgenerational effects such that offspring from a cannabis user are more prone to use opiates.
Editors Note: Youngsters need to know two things.
1. Any supposedly legitimate drug bought on line may look like the real thing, but it is all-too-often laced with fentanyl which can kill someone in 5 minutes. No street-bought drug is safe, no matter how real it looks.
2. Marijuana will not kill you, but can make you psychotic for the rest of your life. The widely circulated notion that pot is safe is just a conspiracy by the plant growers to make money and by politicians who are ignorant of the facts. Pot doubles the rate of paranoia in the general population and if you have a good functioning genetic (val158val) version of COMT, this works too well to deplete dopamine in the prefrontal cortex and further increases the risk of paranoia and psychosis.
DRAMATIC PROPHYLACTIC RESPONSE TO NIMODIPINE: A Case Report
(This is an invited contribution by Robert Westhead.)
This 50 year old man had a lifetime of incapacitating rapid cycling (10 days up and 10 days down) bipolar I disorder, but then for the past 4 years has had a complete remission on nimodipine (60mg QID). He remains on lithium (800mg), and of his other long-term medications, he has titrated quetiapine down from 800mg to 50mg and has discontinued phenelzine.
He had previously failed to respond to combinations of:
· Lithium
· Anticonvulsant mood stabilizers (including divalproex sodium, lamotrigine, carbamazepine and pregablin)
· Atypical antipsychotics (including quetiapine, aripiprazole and lurasidone)
· Antidepressants (including SSRIs eg citalopram and sertraline, NSRIs eg venlaflaxine and mirtazapine, and a MAOI eg phenelzine)
· Thyroxine
· Propranolol
· Clonazepam
He wanted to highlight this dramatic response to nimodipine in combination with lithium as this dihydropyridine calcium channel blocker is not well known or frequently used for its prophylactic effectiveness.
He noted that as well as stopping the rapid cycling, the nimodipine has provided complete relief from comorbid social anxiety symptoms and remediated cognitive and memory impairment.
This response to nimodipine potentially also has pathophysiological implications. Nimodipine directly blocks the CACNA1C calcium influx gene that has repeatedly been associated with vulnerability to depression, bipolar disorder, and schizophrenia in gene wide association studies. This patient does not know whether he carries this gene variant, but assays for it are routinely available as performed by the company Genomind.
Thus, it remains an open question as to whether those who have the CACNA1C variant would be more responsive to nimodipine compared to those without the variant. Certainly, the efficacy of this agent in treatment of patients with bipolar disorder deserves further consideration and study.
Sleep Disturbances in Pediatric Bipolar NOS is the Same as in BP I
Gianni Faedda reported in Frontiers in Psychiatry (2012) that decreased need for sleep is as prominent in BP NOS children as in those with BP I. So it appears that with the exception of only brief periods of mania in BP NOS, these children have similar characteristics to those with full blown BP I. Thus in addition to the briefer periods of mania, one should be on the look out for all the symptoms of bipolar disorder that are not typical of ADHD, including brief or extended periods of euphoria, decreased need for sleep, more extreme degrees of irritability and poor frustration tolerance, hallucination, delusions, suicidal and homicidal ideation, more severe depression, and increases in sexual interest and actions. When these are present, the bipolar mood instability should be treated first and only then small doses of psychomotor stimulants can be used to treat what ever residual ADHD remains. The typical symptoms of ADHD are very of present and comorbid in childhood onset bipolar disorder and cannot be used to discriminate the two diagnoses. The children with BP NOS are as dysfunctional as those with BP I and take longer to stabilize, so pharmacological treatment may need to be intensive, multimodal, and supplemented by Family Focused Therapy (FFT) or a related family therapy. It is most often not conceptualized as such, but BP NOS as well as BP I should be considered as a medical emergency and handled by a sophisticated pediatrician and/or referred for psychiatric consultation and therapy. The longer bipolar disorder is not treated, the worse the outcome is in adulthood.
Two different subtypes of early onset unspecified bipolar disorder (USBD)
The first subtype is classical BP NOS (Not Otherwise Specified) having all the characteristics of full-blown bipolar disorder except for only having brief durations of mania and responding to conventional treatment. The second is what is now called Temperature and Sleep Dysregulation Disorder (TSDD) and was formerly described by D. Papolos as the Fear of Harm (FOH) syndrome, and requires a different treatment approach.
Clinicians should be alert to unique symptoms in children who might have TSDD as such a diagnosis would lead to a unconventional treatment paradigm. We emphasize the importance of specifically asking parents about evidence of over heating (red face and red ears) and high tolerance for cold (going outside markedly under-dressed) and the presence of fear of sleep and horrific nightmares, as these may lead one to consider the diagnosis of TSDD.
If these two novel aspects (temperature and sleep dysregulation) occur in the presentation of a highly fearful and behaviorally dysregulated child with bipolar-like symptoms, these may lead to the consideration of an unconventional treatment paradigm. It utilizes 1) high dose lithium; 2) clonidine and other practical approaches to achieve cooling and relieve over heating; and 3) ascending doses of intranasal ketamine (as described by Papolos et al 2013; 2018). This may be of considerable clinical importance as a large group of children with this unique presentation respond very poorly to conventional treatments for bipolar disorder and remain highly impaired and dysfunction throughout their childhood and adolescence.
If these children instead are treated with: lithium (to achieve blood levels of 1.0 meq/L or higher); clonidine (0.1- 0.3mg IR and 0.1mg ER at noon and HS) and other practical ways to achieve cooling; followed by ascending intranasal doses of ketamine (starting at 20mg and increasing toward 80-260mg/day, repeated every 2-3 days), marked improvement can be achieved. This occurs in conjunction with ketamine’s positive effects on fear and aggressive behaviors in association with its ability to reduce core body temperature.
We highlight this potential alternative treatment approach as long term positive effects have been achieved with it in open case series (Papolos et al 2013; 2018 ). The efficacy of this treatment approach has not been validated in controlled clinical trials, but we believe wider recognition of the two subtypes of USBD– BPNOS and TSDD,– will lead to more systematic research on treatment. Actively looking for the unique features of TSDD and pursuing its unconventional treatment may lead to long term positive effects in a child previously viewed as having an intractable psychiatric illness.
Lithium is a Lifesaver in Bipolar Disorder
Batya Swift Yasgur MA, LSW reported in Medscape Medical News on November 28, 2022 that “Mood stabilizers protect against suicide and all-cause mortality in patients with bipolar disorder (BD), including natural mortality, with lithium emerging as the most protective agent, new research suggests.
Investigators led by Pao-Huan Chen, MD, of the Department of Psychiatry, Taipei Medical University Hospital, Taiwan, evaluated the association between the use of mood stabilizers and the risks for all-cause mortality, suicide, and natural mortality in over 25,000 patients with BD and found that those with BD had higher mortality.
However, they also found that patients with BD had a significantly decreased adjusted 5-year risk of dying from any cause, suicide, and natural causes. Lithium was associated with the largest risk reduction compared with the other mood stabilizers.“
Intermittent theta burst magnetic stimulation (iTBS) is FDA approved.
As reported in Psych. News:?The Food and Drug Administration (FDA) has cleared the SAINT Neuromodulation System for the treatment of refractory depression in adults, Magnus Medical Inc. (the manufacturer of the product)?announced?Tuesday. SAINT is a?modified form of transcranial magnetic stimulation?(TMS) that compresses weeks of conventional TMS therapy into just five days”. ?Regular TMS takes 20-30 minutes per daily session while iTBS takes about 5 minutes and thus can be applied many times in a single day. ?”As demonstrated in a clinical trial?published?in?The American Journal of Psychiatry, Montgomery-Åsberg Depression Rating Scale (MADRS) scores dropped by 62% among participants following five days of SAINT stimulation compared with a 14% drop among participants receiving sham stimulation. These improvements were sustained over a four-week follow-up.” ?The method was developed by Nolan Williams and he used MRI to best target the site of stimulation
Cannabidiol (CBD) does not make cannabis safer
Amir Englund et al reported in Neuropsychopharmacology in A randomised, double-blind, cross-over trial of cannabis with four different CBD:THC ratios that CBD did not protect against the adverse effect of THC. These included impaired delayed verbal recall ( p?=?0.001) and induced positive psychotic symptoms on the PANSS ( p?=?2.41?×?10–5).
Editors Note: Not only does marijuana impair memory, it is a risk factor the onset of bipolar disorder and schizophrenia. When pot is used by a person with a unipolar or bipolar mood disorder, there are increases in depression and anxiety and an overall less favorable course of illness. If a person with a mood disorder uses heavy amounts of marijuana, they could consider buying N-acetylcysteine (NAC) 500mg and increasing the dose to 1,000mg twice a day within a week as this has been shown to decrease drug use compared to placebo in adolescents and young adults using and abusing pot. Most people who sell pot, are not well-informed about its dangers and just want to make money.
