PANS and PANDAS: What Indian Parents Are Missing
One week your child is fine. The next week, almost overnight, they are washing their hands a hundred times a day, refusing food they have always loved, and crying at bedtime in a way you have never heard before. The paediatrician suggests anxiety. A child psychologist suggests OCD. Nobody mentions PANS or PANDAS. For a number of Indian families, this is exactly how the story begins.
This article is a careful walk through what PANS and PANDAS are, why Indian children are often missed and how to find the right team without losing months to the wrong door.
What PANS and PANDAS actually describe
PANS stands for Paediatric Acute-onset Neuropsychiatric Syndrome. PANDAS is a subset: Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections. The shared idea is that an infection or other immune trigger causes the body to react in a way that affects the brain, producing a sudden change in behaviour, mood, eating or movement.
The hallmark is the suddenness. These are not children who slowly develop OCD or anxiety over a year. They are children who change in days or weeks, often after a sore throat, viral fever or other illness. The OCD, food refusal, separation anxiety, tics or rage episodes appear with a clear before-and-after that the family can usually date.
PANDAS specifically follows a strep infection. PANS can follow strep, mycoplasma, influenza, a viral illness, or sometimes no identifiable trigger. The mechanism is thought to involve the immune system mistakenly affecting the basal ganglia of the brain.
Why Indian children are often missed
There are several reasons PANS and PANDAS are under-recognised in India. The first is that paediatricians and child psychiatrists are not routinely trained to look for them. The diagnosis was named in the 1990s and is still actively debated, so it is not always part of standard textbooks. Many doctors will treat the symptoms as primary OCD or anxiety without considering an inflammatory cause.
The second reason is that strep throat is so common in Indian children that a recent infection rarely seems remarkable. Parents may not connect a routine fever from three weeks ago to today's washing rituals. Without that link, the timeline that makes PANS distinctive gets lost.
The third reason is access. Investigating PANS properly involves blood work, sometimes an ASO titre or anti-DNase B, a careful infection history and ideally a paediatric neurologist or immunologist involved. In smaller cities this combination is hard to assemble. Families who can travel to Mumbai, Bangalore, Delhi or Chennai often only get the right workup after months of dead ends.
The sudden-onset pattern parents notice
What parents describe most clearly is the speed. A child who was managing school last month is now refusing to leave the bedroom. A child who ate everything is now eating only two foods because of contamination fears. Handwriting deteriorates. Sleep collapses. There may be tics that were not there before. There may be rage episodes that feel like a different child.
OCD-like behaviours are extremely common in this presentation. So is severe separation anxiety. Some children develop urinary frequency, sensory intolerances or a sudden refusal to chew. The combination of two or more of these, appearing within days of each other and within weeks of an infection, is the pattern worth flagging to your doctor.
If your child's pattern looks more like a slow developmental difference, our piece on telling OCD apart from autistic rigidity may be a better starting point. PANS is specifically about sudden change, not lifelong patterns.
Which doctors to involve and in what order
Start with a paediatrician who is willing to listen carefully to the timeline. Bring a written summary of what changed, when, and what infections occurred in the months before. If you do not yet have a doctor who takes the timeline seriously, our guide on choosing a developmental paediatrician in India can help you find one.
From there, the team usually expands to include a paediatric neurologist, a child psychiatrist who knows about PANS, and sometimes an immunologist or rheumatologist. A speech, ENT or rheumatology referral may be added depending on findings. The order matters less than coordination. One doctor should hold the overall plan so that each test feeds into a single picture.
Investigations typically include a throat culture, ASO and anti-DNase B titres, a complete blood count, inflammatory markers and sometimes more specialised tests. None of these results alone confirm PANS or PANDAS. The diagnosis remains primarily clinical, built on the timeline and the symptom pattern.
Treatment options and what to expect
Treatment usually has three layers. The first is treating any underlying infection. If strep is present, antibiotics are given. Some children improve dramatically within days. Others need longer courses or repeated treatment as infections recur.
The second layer is symptom management. Cognitive behaviour therapy adapted for younger children helps with the OCD and anxiety. Behavioural support helps the family hold steady through rages. Medication may be used cautiously, but children with PANS often respond unusually to standard psychiatric medications, so dosing should start low and go slow.
The third layer, used in more severe or persistent cases, is immune-modulating treatment such as a longer course of anti-inflammatories or, in specialist settings, intravenous immunoglobulin. This is not a first step. It is reserved for children who do not respond to the earlier layers and is decided in consultation with a paediatric neurologist or immunologist familiar with PANS.
Carely's at-home therapy team often supports families during flares by adapting the therapy plan rather than pushing through. The goal is to hold gains, not chase new ones, until the flare settles.
Supporting your child through flares
PANS and PANDAS tend to follow a waxing-and-waning pattern. Children often improve and then flare again, usually with new infections, sometimes for no obvious reason. Parents quickly learn to recognise the early signs of a flare in their own child. For some it is sudden handwriting changes. For others it is a return of food refusal or a familiar tic.
During flares, expectations need to be lowered without guilt. School may need to know your child is in a flare and that workload should be reduced. Therapy goals should pause where needed. Sleep and nutrition should take priority. The flare is not behaviour, it is biology, and treating it as misbehaviour makes everything worse.
Between flares, work on the parts of life the flares disrupt. Friendships, hobbies, family routines. These are the anchors that keep your child's sense of self intact across the ups and downs. Our broader overview of specific childhood conditions sits alongside this piece as further reading.
Frequently asked questions
Is PANS or PANDAS officially recognised in India?
The diagnosis is recognised by individual specialists who are familiar with the literature, but it is not yet part of routine paediatric training in most Indian medical colleges. Specialist centres in larger cities are increasingly comfortable with it.
My child has had OCD for years. Could it still be PANS?
PANS specifically describes sudden onset. If symptoms began gradually over months or years, the picture usually fits a primary OCD or anxiety diagnosis rather than PANS. A flare on top of long-standing OCD is possible but uncommon.
Will antibiotics cure my child?
Antibiotics can dramatically help if there is an active strep or other treatable infection. They do not address the underlying immune sensitivity, so flares can recur with future infections. Treating each flare promptly tends to shorten and soften them over time.
Do we need to travel to a metro city for diagnosis?
Not always for the initial workup, but for full assessment and complex treatment, a paediatric neurologist or immunologist familiar with PANS is currently most accessible in larger cities. Telemedicine consultations have made the gap smaller.
Will my child grow out of this?
Many children improve substantially over months to years, particularly when flares are treated promptly. Some continue to have a low background of OCD or anxiety into adolescence. The trajectory varies widely, and active treatment changes the long-term outcome.
Should we tell school?
Yes, but selectively. The class teacher and the school counsellor should know your child has a medical condition that affects behaviour during flares. They do not need every detail. They need a one-page summary, a flare plan and a person at school they can call when something changes.
