PANS/PANDAS Awareness Day 2026: October 9, Symptoms, Meaning & Awareness

PANS/PANDAS Awareness Day 2026 will be observed on Friday, October 9, 2026. The annual observance aims to improve understanding of two uncommon and often misunderstood neuropsychiatric conditions: Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS).

Awareness organisations use October 9 to bring families, clinicians, educators and supporters together around recognition, research, appropriate evaluation and support. The PANDAS Physicians Network identifies October 9 as PANS/PANDAS Awareness Day and says the day is intended to increase awareness of treatable immune-mediated neuropsychiatric conditions.

PANS/PANDAS Awareness Day 2026: Quick Facts

Observance	PANS/PANDAS Awareness Day
Date	October 9, 2026
Day	Friday
Main focus	Awareness, education, research and support
Conditions	PANS and PANDAS
Audience	Families, healthcare professionals, educators and the public

What Are PANS and PANDAS?

PANS stands for Pediatric Acute-onset Neuropsychiatric Syndrome. The PANDAS Physicians Network describes it as a clinical syndrome involving the sudden onset of obsessive-compulsive symptoms and/or restrictive eating accompanied by other acute neuropsychiatric symptoms.

PANDAS stands for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections. It refers to a subset associated with Group A Streptococcus and specific clinical criteria.

These terms describe clinical conditions that require professional evaluation. An awareness article cannot determine whether a particular child has PANS, PANDAS or another medical condition.

When Is PANS/PANDAS Awareness Day 2026?

PANS/PANDAS Awareness Day 2026 is on October 9, 2026. PANDAS Network states that it recognises PANDAS/PANS Awareness Day each year on October 9, while PANS PANDAS UK describes October 9, 2026 as a global awareness event.

Why Is PANS/PANDAS Awareness Day Important?

1. Recognising abrupt changes

PANS/PANDAS can involve a sudden change in behaviour, eating, emotional regulation, movement or other neuropsychiatric functions. Awareness helps families understand that an abrupt change deserves appropriate professional attention.

2. Supporting families

Families may face uncertainty when symptoms appear suddenly. Awareness activities create opportunities to find reliable information and connect with other families and professionals.

3. Improving professional education

Awareness organisations emphasise education for clinicians and multidisciplinary collaboration. PPN provides clinical resources, diagnostic flowcharts and research information for professionals.

4. Encouraging research

Research is an important part of improving understanding, diagnosis and management. PPN highlights ongoing research and collaboration with universities and clinical researchers.

Commonly Described Signs and Symptoms

The PANDAS Physicians Network states that PANS/PANDAS can involve an abrupt onset of obsessive-compulsive symptoms, restrictive eating and other neuropsychiatric changes. Associated features can include anxiety, emotional or behavioural changes, sensory or motor abnormalities, sleep problems, urinary symptoms and changes in school performance.

Area	Examples described by PPN
Behaviour	Behavioural regression, irritability or sudden behavioural change
Emotional health	Anxiety, separation anxiety and mood changes
Obsessive-compulsive symptoms	Sudden onset or recurrence of OCD symptoms
Eating	Sudden restrictive eating
Motor/sensory function	Tics, motor abnormalities or sensory amplification
School functioning	Sudden deterioration in school performance or handwriting
Other physical/neurological features	Urinary symptoms and sleep disturbances

These symptoms are not specific to PANS/PANDAS. Similar symptoms can occur with other conditions, which is why professional assessment is important.

PANS and PANDAS: What Is the Difference?

Feature	PANS	PANDAS
Name	Pediatric Acute-onset Neuropsychiatric Syndrome	Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections
Core presentation	Acute onset of OCD and/or restrictive eating with additional symptoms	Acute onset of OCD and/or tics with additional clinical features
Infection relationship	Not limited to streptococcal infection	Associated with Group A Streptococcus
Diagnosis	Clinical evaluation using established criteria	Clinical evaluation using established criteria including the relevant infection relationship

PPN notes that PANS does not require a streptococcal infection, whereas PANDAS is defined as a subset associated with Group A Streptococcus.

What Causes PANS/PANDAS?

The biology of PANS/PANDAS is an area of ongoing medical research. PPN describes these conditions in terms of immune-mediated neuroinflammation and notes that PANS can be associated with different infections, while PANDAS has a specific association with Group A Streptococcus.

It is important not to interpret an infection followed by a behavioural or psychiatric change as proof of PANS or PANDAS. Diagnosis requires appropriate clinical evaluation and consideration of other possible explanations.

Diagnosis and Professional Evaluation

PANS/PANDAS diagnosis is clinical and can be complex. PPN provides diagnostic flowcharts and consensus-based resources for clinicians. Its published PANS criteria include abrupt onset or abrupt recurrence of OCD or restrictive eating, at least two additional acute neuropsychiatric symptoms, and the requirement that symptoms are not better explained by another known neurological or medical disorder.

Why professional evaluation matters

Several medical and psychological conditions can produce overlapping symptoms.
A sudden change in a child’s behaviour or functioning can have multiple possible causes.
Clinical history and examination are important.
Healthcare professionals can decide which investigations are appropriate.
Families should avoid self-diagnosis based only on online symptom lists.

How PANS/PANDAS Can Affect School Life

Sudden neuropsychiatric and behavioural changes can affect attendance, concentration, handwriting, eating routines, peer relationships and academic performance. PANS PANDAS UK’s 2026 awareness programme includes a school initiative called Go Green with Glitch, designed to promote awareness and inclusion for children and young people affected by PANS and PANDAS.

Schools can respond constructively by listening to families, communicating with appropriate professionals and following their own safeguarding, attendance and support procedures. Individual accommodations should be based on the child’s circumstances rather than assumptions.

How Families Can Support a Child

Record sudden changes in symptoms, behaviour or daily functioning to discuss with a healthcare professional.
Keep communication calm and supportive.
Maintain appropriate school communication when symptoms affect attendance or learning.
Use reliable medical and patient-support resources rather than social-media claims.
Protect the child’s privacy when sharing information online.
Seek professional help when symptoms are sudden, severe or concerning.

How Teachers and Schools Can Help

Listen and communicate

Teachers may notice changes in concentration, handwriting, behaviour or participation. Sharing observations through appropriate school channels can help families and professionals build a clearer picture.

Provide reasonable flexibility

Where appropriate, schools may consider individual support arrangements under their existing policies. The right approach depends on the child’s needs and the school’s applicable procedures.

Promote inclusion

Awareness should not become labelling. Children experiencing health-related difficulties should be treated with dignity and included in school life as far as reasonably possible.

PANS/PANDAS Awareness Day 2026 Activities

Practical Awareness Checklist

Know the terms: Understand what PANS and PANDAS stand for.
Recognise abrupt change: Sudden and dramatic changes in behaviour, eating or neuropsychiatric symptoms should not simply be dismissed.
Seek appropriate help: Discuss concerning symptoms with a qualified healthcare professional.
Support school communication: Share relevant observations through appropriate channels.
Use reliable sources: Prefer medical organisations, professional guidance and established patient organisations.
Protect privacy: Do not publicly share a child’s medical details without appropriate consent.

What Not to Do

Do not diagnose PANS or PANDAS from a social-media checklist.
Do not assume that every sudden behavioural change is caused by an infection.
Do not stop or start medical treatment without professional advice.
Do not present disputed or emerging research as settled medical fact.
Do not stigmatise children because of sudden changes in behaviour or school performance.

Research and the Future

Research remains important because scientists and clinicians continue to study the biological mechanisms, diagnostic approaches and management of PANS/PANDAS. PPN maintains research and clinical-literature resources and reports collaborations with academic institutions.

For families, this means awareness should be connected to evidence-based information rather than sensational claims. New research may change understanding over time, so medical guidance should be interpreted in the context of current professional evidence.
