Brita List - Clinical Psychologist

Brita List - Clinical Psychologist Clinical Psychologist. PhD Candidate. Niche: PANS/PANDAS. Sydney Australia I am located in Sydney, Australia.

I'm a Clinical Psychologist and board-approved supervisor with a focus on treating anxiety and mood disorders alongside acute and chronic health conditions. Specifically, I have interest and experience in PANS/PANDAS, consistently managing multiple PANS clients (see my treatment approach on my website). I've also completed the Gut Smart course for Psychological Health in Inflammatory Bowel Disease (IBD). I offer appointments on Wednesdays in the treating rooms of Mind & Presence, Pymble, NSW. I have extensive experience working with children, youth and adults with anxiety and mood disorders at the Emotional Health Clinic, Macquarie University (ongoing). I supervise Master of Clinical Psychology students on placement, flexibly delivering the ‘Cool Kids Program’ for anxiety in school-aged children and youth. I have also served as a treating clinician on various research trials, providing assessment and treatment for children, adolescents, parents, and older adults experiencing mood disorders and somatic symptoms, emotion regulation issues, and seeking a more fulfilling life. In addition to working with anxiety, mood and emotion dysregulation concerns, I also provide interventions for when mental health is impacted by acute and chronic health conditions. My approach involves utilising Cognitive Behavioural Therapies (CBT) and other evidence-based modalities. I prioritises being neurodiverse-affirming and LGBTQIAP+🏳️‍🌈 affirming; valuing and celebrating diversity while focusing on client-centred, functional goals. I work with and differentiates between challenges best addressed through CBT and those requiring accommodations to facilitate meaningful engagement in life. I am interested in empowering people of all ages with:
* Anxiety e.g,. social, separation, general, specific phobias, selective mutism, panic… including but not limited to: Accredited Program Provider for the Cool Kids program
* Chronic or acute low mood
* Neurodiversity e.g., Autistic, ADHD, OCD, Tourette Syndrome, twice exceptional, learning differences, sensory overwhelm, ARFID, rages…
* Complex health issues e.g., PANS/PANDAS, IBS, IBD, POTS, EDS, ME/CFS, FND, long covid, autoimmune, hormonal, chronic pain…
* Navigating identity, life stages and times of transition e.g., q***r/ LQBTQI+, interpersonal relationships and building confidence, HSC, tertiary education, relationships, career, parenthood, burnout, retirement, impact of health…
* Other concerns like emotion dysregulation/outbursts, bullying, peer relationships, assertive communication skills and “school can’t” / difficulties attending school. Please note: for children approximately 6 and younger, they are not developmentally ready to engage in strategies within my skillset (CBT). Sessions will predominately be working with parents to identify parent-guided opportunities for change. Professional Memberships:
Australian Clinical Psychology Association (ACPA)

People with PANS/PANDAS are trying so hard, all the time: "high-masking". Until they fall apart in the safety of home, or until they can't any more.

PANS/PANDAS Training for Mental Health Clinicians

February 27 | 10 AM – 12 PM | 2 CEs

I’m excited to share an introductory CE training I’ve been developing on PANS/PANDAS—conditions that can cause sudden-onset OCD, tics, eating restriction, anxiety, and dramatic behavioral changes.

Families often describe it as “my child went to bed one kid and woke up another.” Despite how acute and debilitating these symptoms can be, access to informed medical and psychological care is limited. Advocacy and increased training on these disorders is essential to help families receive proper assessment, diagnosis, and treatment.

Training Includes:

-Definitions: PANS vs. PANDAS
-Differentiating from non-PANS OCD & neurodevelopmental disorders
-2025 research updates: immune dysregulation, neuroinflammation, RNA sequencing
-Evidence-based interventions: ERP, SPACE, DBT crisis strategies
-ARFID/eating restriction within PANS presentations
-Scope of practice & referral pathways with medical teams
-Worksheets & flowcharts for assessment, referral, and treatment planning

Why this training matters:

-Families often come to therapists first
-Proper rule-outs are essential, even when it’s not PANS
-Coordinated mental health + medical care is critical when it is PANS

CE Information:

-2 CEs for NYS LMHCs, LMFTs, LCSWs, LMSWs, LCATs & Psychologists
-Provided through Hudson Valley Professional Development

This 2h webinar is free! It was so good to hear from leaders in this field about what's happening right now in their work. Hopefully they will make more of these webinars, too! I will go through my notes and share my highlights over the next month or so.

Watch experts examine the roles of neuroimmune and epigenetic factors in children with PANS/PANDAS, and discuss whether these conditions are best understood as autoimmune, autoinflammatory, or both. The on-demand video webinar is now available at https://www.pandasppn.org/neuroimmune-epigenetic-webinar

This webinar is presented in collaboration with PANDAS Physicians Network and PANDAS Network.

“Abstract: Patients evaluated for PANS at the IBH Clinic showed diverse clinical presentations and illness courses over the long term, with most experiencing a relapsing-remitting clinical course but some exhibiting persistent symptoms. Many experienced neuropsychiatric flares before meeting PANS classification criteria. This underscores the importance of clinicians being vigilant for new neuropsychiatric symptoms in pediatric patients, even if they do not immediately meet PANS criteria. Based on these data, we propose terms and definitions for characterizing patient status, flares, and clinical course, which we hope the clinical and research communities will build on and refine.”

I always hope my clients can return to baseline! I have seen recovery, what was "lost" returned to them! Biological intervention is a priority, so keep looking! I also assembled some ideas for looking further, here:

A child can unravel completely while their MRI remains entirely normal.
That single fact changes everything.
The brain is not broken.
The regulation is.

Parents see the change first.
A child who connected now withdraws.
A child who coped now startles.
A child who spoke now struggles for words.
The Child, who was steady now swings between fear and agitation.

None of this appears on a scan because the structure is intact.
It’s the regulatory environment that has collapsed.

I came across a 2020 longevity study that should have rewritten the conversation.
Neurons under pressure don’t lose their abilities.
They lose access to them.
The chemistry shifts.
The signalling falters.

It means the problem is access, not ability - and access can be restored.

When inflammation settles, when infections clear, when the gut stops sending danger messages, when the metabolic load drops, the child returns.
Not because they relearn everything.
Because the brain becomes accessible again.

This is why the return of function can be sudden, precise and unmistakable.
Why a word reappears.
Why a fear drops.
Why a meltdown vanishes.
Why a child reconnect as if pressure has finally lifted from their nervous system.

Regression is not loss.
It’s blocked access to the abilities a child already holds.

Different learning pathways in the brain!

In treatment during PANS flares, I advocate for accommodation rather than the usual anxiety approach of nudging people out of their comfort zones - due to considerations for greatly reduced "window of tolerance". A terrified person, with impaired capacity to regulate, is not going to learn that the situation is safe, rather, they 'learn' it is very dangerous!

I've been finding more and more hints that while access to prior and new prodecural (habit-forming) learning seems disrupted in PANS (disrupted basal ganglia functioning), the amplified amygdala activity is part of super trauma "learning". In severe flares, the brain can't learn/initiate CBT strategies but its primed to learn threat.

And here's another one of those hints..!!

On children's compliance and learning when to not follow the rules, because not everyone in authority is using power responsibly. An important concept, but actually learning this is complex - it takes development of self-awareness and learning about boundaries!
I often hear kids with PANS trying really hard to comply, masking, and trying to tell people in authority when they've reached their limit, and those boundaries are dismissed. This leads to *preventable* escalations and risk to self and others.
