Central to this integrative model is the use of advanced diagnostic tools. This can include brain imaging, which allows us to gain deeper insights into each patient’s unique needs.

Brain Imaging

Understanding Brain Imaging

Brain imaging techniques have opened an exciting window into the inner workings of the mind. Non-invasive imaging modalities utilize different properties that include energy waves and radioactive tracers.
This allows for visualization of structure and function within a living brain. These insights are furthering our understanding of the neural networks underlying mental illness.

Addressing Complex Factors Contributing to Mental Illness

Ongoing research in brain scanning aims to clarify the complex relationships between the following contributors to mental illness:
  • Genetic risk factors
  • Neural circuits
  • Biochemical processes

Structural Imaging Through MRI

Structural imaging techniques like magnetic resonance imaging (MRI) provide clear pictures of brain anatomy. MRI uses strong magnetic fields and radio waves to differentiate tissues based on water content.

Detecting Brain Abnormalities Through MRI

The high-resolution images detect subtle abnormalities in the following:
  • Size of gray or white matter 
  • The shape of different areas of the brain
  • Symmetry of brain matter
These aspects may reflect on psychiatric illnesses.

Functional Imaging Modalities

A structural MRI allows for visualizing anatomical correlates of mental illness. New functional imaging modalities have also emerged to capture deeper insights into neural activity.

Brain Scanning Tools Used in Treatment

There are several techniques that may be utilized in mental health treatment, such as:
  • Functional MRI (fMRI)
  • Positron emission tomography (PET)
  • Single-photon emission computed tomography (SPECT) 
These options go beyond static structure. They directly measure activity levels across brain regions related to mental processes.

The Function of fMRI and PET Imaging

The fMRI detects changes in blood flow to track brain areas during the following:1
  • Cognitive activity
  • Sensory input
  • Emotional processing
  • Motor tasks
PET imaging uses radioactive tracers to map resting or challenged whole-brain metabolism.2

The Advantages of Functional Scans

Together, functional scans can identify potential biomarkers. This identification is based on underlying neurobiology rather than anatomical structure alone.
Clinicians can now pinpoint specific neural circuits and hubs which harbor abnormal connectivity or activation patterns contributing to these psychiatric symptoms:
  • Altered structure and function in emotional processing areas like the amygdala
  • Weak connectivity between prefrontal cognitive regions and limbic structures
  • Imbalances between large-scale brain networks 

Advancements in Brain Imaging Diagnostics

Advanced analysis techniques are also enhancing the utility of brain imaging for mental health.
Multimodal imaging combines the following for a more complete diagnostic picture:
  • Structure
  • Function
  • Chemical data
As a result, clinicians gain an increasingly detailed map of each patient’s unique neural vulnerabilities and assets. This helps to guide precise diagnosis and personalized interventions.

The Importance of an Integrated Treatment Approach

There are still limitations in directly linking brain scans to behaviors and symptoms. Caution must be taken when interpreting images, as many factors shape brain structure and function over a lifetime.

Integrative Treatment at Mind Body Optimization

While imaging reveals biological correlates of illness, psychological and social influences are also at play.
The core of MBO’s clinical philosophy is sustainable healing — which requires addressing the whole person.

Utilizing Brain Images with Other Data

At Mind Body Optimization, our clinical team will soon utilize brain imaging like transcranial magnetic stimulation (TMS) to gain biological insights into each patient’s condition. This is used alongside psychological and environmental data.

This integrative assessment approach allows us to develop customized treatment plans. Our goal is to target specific neural vulnerabilities related to individual symptom history.

Our Treatment Model

An integrative treatment model coordinates the following services:
An essential component of this whole-person approach is the use of advanced brain imaging diagnostics. Used responsibly alongside other assessments, brain imaging has become an invaluable tool for unraveling the neurobiology of psychiatric disorders.

Key Functional Brain Imaging Modalities

Functional brain imaging allows clinicians to visualize activity across neural regions and networks related to mental processes and psychiatric illness.3

Functional MRI (fMRI)

A functional MRI (fMRI) is widely used as a neuroimaging tool in research and clinical settings. It measures changes in blood oxygen level reliance on neural activity. This maps high activity in the brain during specific tasks or rest states.

How Does fMRI Work?

Powerful magnetic fields detect increased blood flow to active neurons. The high spatial resolution can pinpoint activation down to subcortical structures.
Patients perform cognitive exercises targeting functions including these while scans track networks:
  • Emotional
  • Sensory
  • Motor

Advancements in fMRI

Recent advances are pushing fMRI to even greater precision in decoding mental states. Machine learning classifiers can now reconstruct complex emotional experiences from scan patterns alone.4
Real-time fMRI enables patients to watch brain activity directly. This aids in the practice of self-regulation therapies through biofeedback.5
Ultra-high field 7T fMRI maps individual neural architecture. This methodology delivers unprecedented resolution of structural connections.6

Positron Emission Tomography (PET)

PET imaging uses radioactive tracers like fluorodeoxyglucose (FDG) which accumulate in metabolically active brain tissue. The signals emitted as the tracers decay are detected by the scanner. Then they are reconstructed into 3D maps to reflect whole-brain activity.

A Closer Look into PET Scanning

PET scans effectively measure baseline functioning and probe neurotransmitter activity. Newer tracers like Pittsburgh Compound B (PiB) bind to amyloid beta plaques in Alzheimer’s.7
Other ligands attach to receptors like those for dopamine or serotonin. This chemical specificity aids diagnosis and treatment monitoring.

Advancements in PET

Recent PET advances include the following features:
  • Higher sensitivity detectors for faster, lower dose scans
  • Fusing structural, functional, and chemical data into powerful diagnostic images
  • Portable PET scanners to support bedside imaging

Ongoing PET Developments

Ongoing PET developments target the following features:8
  • Improved spatial resolution 
  • Specific tracers for inflammation and tau proteins
  • Identifying other indicators of neurodegeneration and psychiatric illness

Single-Photon Emission Computed Tomography (SPECT)

SPECT imaging relies on intravenous radioactive tracers. These cross the blood-brain barrier and concentrate in active neural tissue. SPECT detects photons emitted directly from the tracer compound as it decays.
SPECT scans measure resting cerebral blood flow, indicating areas of unusually high or low activity. The results are color-coded for straightforward interpretation of potential dysfunction.

Recent Advances in SPECT Technology

Recent advances in SPECT technology means:9
  • Faster scanning
  • Improved image quality
  • Tracers targeting specific neurotransmitter activity, perfusion, and neuroinflammation
Quantitative SPECT analysis is also emerging to move beyond visual reads. This includes objective clinical decision-making based on numeric regional activity levels.

Personalized Brain-Based Treatment

As functional imaging continues advancing, clinicians gain an increasingly detailed window into the interactions between brain networks and mental health. This provides a guide to precise, personalized psychiatry.
Advanced assessments allow clinicians to pinpoint neural causes of a patient’s symptoms. This data is then used to develop personalized treatment plans targeting the underlying biology.

Treatment Interventions at Mind Body Optimization

Brain-based treatment interventions can include:
  • Therapy approaches informed by neuroscience
  • Brain stimulation techniques like TMS
  • Lifestyle changes to support cognitive function
By incorporating cutting-edge brain imaging diagnostics into integrative treatment, MBO empowers patients with a deeper understanding of mental health at a neural level.
This means that we treat more than just symptoms — we treat the whole individual.

Brain Imaging in Diagnosis and Treatment

Advances in structural and functional brain imaging are transforming how mental health professionals diagnose psychiatric disorders.
We can identify potential biological markers associated with symptoms. These types of brain scans provide evidence to guide diagnosis and track disease progression.

Treating Major Depressive Disorder

Major depressive disorder (MDD) has known correlations to volume changes visible on MRI.
Meta-analyses consistently show MDD patients have reduced gray matter in the following areas:
  • Hippocampus
  • Putamen
  • Anterior cingulate
  • Frontal lobe regions 
These areas are involved in mood regulation. The hippocampus, critical for memory formation, is often smaller in volume. The putamen, part of the brain’s reward circuitry, also atrophies with recurrent depressive episodes.

Addressing Emotional Dysregulation

Functional MRI reveals additional diagnostic biomarkers in MDD patients. These include the following signs:
  • Aberrant activity in limbic network regions linked to emotional processing
  • Elevated activation in the amygdala to negative stimuli
  • Reduced connectivity in the amygdala with prefrontal cognitive control centers
  • Overactive subcallosal cingulate during resting states
These functional changes reflect emotional dysregulation patterns in MDD.10

Combining Data in Treatment Planning

By combining structural and functional data, clinicians can map the unique neural vulnerabilities underlying symptoms. Having biological markers aids diagnosis and enables early interventions.
Tracking changes in hippocampal volume and reward circuitry over illness courses is also vital. It can predict relapse risk.

New Avenues for Treatment

The growing ability to visualize neural circuit dysfunction is opening new avenues for treatment. Real-time functional MRI biofeedback is being explored by patients to help with mindfulness techniques.

Addressing Treatment-Resistant Depression

For treatment-resistant depression, treatment providers may use the following methods:

  • Amygdala activation through therapeutic interventions
  • Employing positive memory recall 
  • Emotion regulation exercises
With practice, patients learn to modulate limbic hyperactivity. Symptom improvement correlates with strengthened functional connections visible on scans. These connections are between cognitive control and emotional processing regions.11

Non-Invasive Stimulation

Brain imaging is also used to target specific sites with non-invasive stimulation methods. Transcranial magnetic stimulation (TMS) is used to modulate circuit dysfunctions.

TMS uses MRI-guided electromagnetic coils placed against the scalp. This activates cortical tissue and deep structures.

How Can TMS Help Depression?

TMS aims to redress hypoactive dorsolateral prefrontal regions. Stimulating these areas strengthens connectivity in mood-regulating networks. These areas are implicated in executive functions like planning and impulse control.12

TMS as Standard Treatment of Medication-Resistant Depression

TMS has the ability to correct circuit-based biomarkers with targeted stimulation. This supports the incorporation of TMS into standard protocols for treating medication-resistant depression. Imaging biomarkers also predict optimal stimulation targets for better treatment response.

The Benefits of Repeated TMS

Repeated TMS boosts frontal and limbic activity levels. This rebalances brain networks associated with the following:
  • Emotional processing
  • Reward
  • Motivation
  • Cognition
Patients receive daily sessions over several weeks.

Broadening the Scope of Brain Scanning Applications

Most neuromodulation applications currently focus on depression. However, imaging-guided approaches are expanding to understanding other conditions.
These can include the following:
  • Obsessive-compulsive disorder 
  • Addiction
  • Schizophrenia

Brain Scanning for Precise Diagnosis

Identifying the neural correlates behind symptoms enables more precise diagnosis. It also allows for personalized therapeutic interventions to correct dysfunctional networks.

Sustainable Healing and Neurobiology In Mental Health Treatment

While brain imaging and targeted brain stimulation techniques may seem far removed from traditional holistic modalities, they are very much interlinked.
