New Research & Changing Paradigms raise tough questions

5/28/2024

Val's Take/Conjecture

A lot of people got BLIND-SIDED by serious Psychiatric Disorders or Neuro-Developmental Disorders in Adulthood.
- When we're not using any kind of bio-marker that can happen quite frequently.
Paradigms are shifting and if we truly understand the ramifications of those shifts --- it may very well feel like the world has changed.

Once you get to the point of Mitochondrial Dysfunction as it relates to illness and aging, including neuro-developmental and psychiatric disorders---- you are pretty far from the DSM 5.

A lot of researchers are pretty far from the DSM 5.
If we want clinicians and policymakers to catch-up -- we have to provide the SUPPORT for that.

Mental Health Systems and Criminal Justice Systems are inter-dependent. If we have Mental Health Systems that are significantly behind the research --- we're going to have Criminal Justice Systems that are significantly behind the research.

What jumps out to me in the research is the need to understand:

The Neuro-Developmental/Psyschiatric Disorder Continuum and the ramifications of that, including Maternal Immune Activation and Epigenetics
Mitochondrial Dysfunction
Dysregulation of Multiple Systems of the Body, including
- Innate and Adaptive Immunity
- The Microbiome, and
- The Endocrine System

Mitochondria: A Unifying Link for Psychiatric Illness (2024)

In the past few years, as researchers have begun measuring such factors, more and more preclinical and clinical studies have reported abnormalities in brain energy metabolism, electron activity, and genes associated with mitochondrial functions in stress-related disorders, anxiety, depression, bipolar, schizophrenia, and autism spectrum disorders.

Val's Take: Mitochondria is not just arising as a unifying link for psychiatric illness but for illness and aging in general.

For people with neuro-developmental disorders and/or psychiatric disorders -- Maternal Immune Activation and Epigenetics over the lifespan appear to account for Mitochondrial Dysfunction in many cases.

This does include "psychological stress" but it is more than that.

Neuro-developmental & Psychiatric Disorders as forms of premature aging

5/22/2024

Val's Take/Conjecture

We have worked our way to some fundamental questions regarding chronic illness.
To me, the Maternal Immune Activation that is often characteristic of Neuro-Developmental and Psychiatric Disorders is a form of pre-mature aging.
- which is not normally how we think of it --- the person needs better coping skills.
- the person is acting "immaturely"

The study above says we should be looking for the beginnings of Alzheimer's in younger people and I think the research supports going back in utero.
Some researchers are actually saying that we need to understand the GENERATIONAL ASPECTS of Maternal Immune Activation.

More reactive cells and energy issues

Val's Take/ Conjecture

One of the things that CMS did was they partnered with the National Institute of Mental Health for protocols to treat First Episode Psychosis.
It would be good for CMS to partner with the National Institute of Mental Health on addressing energy issues in Neuro-Developmental and Psychiatric Disorders.
It would be good for HUD to partner with states to provide housing for people with neuro-developmental disorders, psychiatric disorders and brain injury who are at risk of institutionalization such as is inherent in homelessness.

The Study of Bipolar Disorder is the Study of Humanity

I think the Study of Bipolar Disorder can also be instructive with regard to other mental disorders --- because there often is a fair amount of overlap.

This video is from 2017.

Dr. McInnis discusses people with bipolar disorder literally having "more reactive cells" and this has a life of its own --- which I would say is epigenetics.

So you can come off as very "reactive" --- because you are.

On the other hand, many people with neuro-developmental and psychiatric "disorders" --- struggle to have enough ATP so that their brains and the rest of their bodies have enough energy to function "neuro-typically" throughout the day.

Maternal Immune activation, Mitochondria Dysfunction, Innate & adaptive Immunity, Epigenetics and Neuro-Developmental and Psychiatric disorders

5/9/2024

Val's Note: There is some important information here --- even if it's jumbled.

The main thing is to start thinking of other systems and processes than we are used to with regard to neuro-developmental & psychiatric disorders.

The epigenetic encoded memory of the innate immune system (2020)

How do innate immune cells affect epigenetic changes?

Stimulation or infection of innate immune cells induces profound epigenetic changes, including the induction of histone modifications and alterations in DNA methylation levels.

Mitochondrial dysfunction as a trigger of innate immune responses and inflammation (2017)

Much research on mitochondrial control of immunity now centers on understanding how mitochondrial constituents released during cellular damage simulate the innate immune system.
When mitochondrial integrity is compromised, mitochondrial damage-associated molecular patterns engage pattern recognition receptors, trigger inflammation, and promote pathology in an expanding list of diseases.

Epigenetics and the Adaptive Immune Response (2013)

" Cells of the adaptive immune response undergo dynamic epigenetic changes as they develop and respond to immune challenge.

"Plasticity is a necessary prerequisite for the chromosomal dynamics of lineage specification, development, and the immune effector function of the mature cell types."

Mitochondrial dysfunction in psychiatric disorders (2022)

"Growing evidence indicates that mitochondrial function plays an important role in developing psychiatric disorders."

And Mitochondrial dysfunction also plays an important role in other deseases:

Mitochondrial dysfunction and psychiatric disorders (2009)

Damage to the mitochondrial electron transport chain has been suggested to be an important factor in the pathogenesis of a range of psychiatric disorders.
Tissues with high energy demands, such as the brain, contain a large number of mitochondria, being therefore more susceptible to reduction of the aerobic metabolism.-
Mitochondrial dysfunction results from alterations in biochemical cascade and the damage to the mitochondrial electron transport chain has been suggested to be an important factor in the pathogenesis of a range of neuropsychiatric disorders, such as bipolar disorder, depression and schizophrenia.

Epigenetics of Ageing and Psychiatric Disorders (2024)

"In the near future, we might be able to replace chronological age with biological age, based on the epigenetic clock, with the promise of providing greater therapeutic benefits.

"A wide range of epigenetic drugs are currently under development at various stages.

"Although their full effectiveness is yet to be realized, they show great potential in the treatment of cancer, psychiatric disorders, and other complex diseases."

Epigenetics and ADHD: Reflections on Current Knowledge, Research Priorities and Translational Potential (2022)

"Attention-deficit/hyperactivity disorder (ADHD) is a common and debilitating neurodevelopmental disorder influenced by both genetic and environmental factors, typically identified in the school-age years but hypothesized to have developmental origins beginning in utero."

. . .

"Epigenetic processes that regulate gene expression, such as DNA methylation, have emerged as a promising molecular system in the search for both biomarkers and mechanisms to address this
challenge. "

Epigenetic mechanism of SETDB1 in brain: implications for neuropsychiatric disorders (2020)

Neuropsychiatric disorders are a collective of cerebral conditions with a multifactorial and polygenetic etiology.

Dysregulation of epigenetic profiles in the brain is considered to play a critical role in the development of neuropsychiatric disorders.

SET domain, bifurcate 1 (SETDB1), functioning as a histone H3K9 specific methyltransferase, is not only critically involved in transcriptional silencing and local heterochromatin formation, but also affects genome-wide neuronal epigenetic profiles and is essential for 3D genome integrity.

Here, we provide a review of recent advances towards understanding the role of SETDB1 in the central nervous system during early neurodevelopment as well as in the adult brain, with a particular focus on studies that link its functions to neuropsychiatric disorders and related behavioral changes, and the exploration of novel therapeutic strategies targeting SETDB1.

Energy Constraints on Brain Network Formation (2021)

Val's Take/Conjecture: I think we could all benefit from eating a better diet, but I think the "hyper-connected brains" of people with neuro-developmental and psychiatric disorders are putting a big strain on the energy needs of the brain.

Unfortunately, this is often coupled with Mitochondrial Dysfunction that seems also to arise from Maternal Immune Activation.

Mitochondria dysfunction in Depression, Suicide, CANCER & Beyond

5/7/2024

One of the things that Orchid is committed to is a "ROOT CAUSE ANALYSIS."

Much of the Neuro-Developmental / Psychiatric Continnuum appears to begin with Maternal Immune Activation and Mitochondrial Dysfunction ----

and that in turn has many cascading effects over the lifespan.
including dysfunction of mitochondria in T-Cells which appears to lead to greater deterioration that would generally be associated with age.

So there "may" be some pre-mature aging as the result of maternal immune activation..

Honing in on Mitochondria Dysfunction appears to be a key to Integrating Developmental, Physical and Mental Health.

Many physical health issues have psychiatric symptoms and many mental health issues do have physical symptoms.

Researchers around the world are focusing on Mitochondria.
