Before the Diagnosis
The window for early intervention is closing. The waiting list is eighteen months long.

Rachel knew before anyone would confirm it.
She knew at eighteen months, when her son Eli stopped adding words instead of gaining them. She knew at two, when the pediatrician told her he was probably a late talker, that boys develop slower, that she should give it six more months. She gave it six more months. She came back. She was told the same thing.
She knew at two and a half when she sat across from a different pediatrician, in a different office, and said: I need a referral for a developmental evaluation. I have been watching my son for a year and something is not right, and I need someone to look at him.
The referral took three weeks. The waiting list for a comprehensive developmental evaluation was fourteen months.
Eli was three years old. The window for early intervention, the period when the developing brain is most responsive to support, closes around five. Rachel did the math in the parking lot and cried.
In the Capital Area, the pathway from a parent notices something to a child receives a diagnosis runs through a small number of specialists who conduct comprehensive developmental evaluations. Developmental pediatricians. Licensed psychologists with specific training in autism assessment. Neuropsychologists. There are not many of them. They are concentrated in hospital systems. Their waiting lists are, and have been for years, measured in months rather than weeks.
This is not a new problem. It is a structural one. The demand for diagnostic services has grown significantly as awareness of autism has increased and as the diagnostic criteria have expanded to capture a more complete picture of who is actually autistic. The supply of providers trained to conduct comprehensive evaluations has not grown at the same pace.
What makes Baton Rouge's version of this problem particularly acute is the age threshold. In the Capital Area, most providers who conduct developmental evaluations focus on young children, generally under the age of seven or eight. Above that age, the options narrow considerably. For adolescents seeking a first diagnosis, or for adults who spent their entire childhoods undiagnosed and are only now understanding why everything has always been harder than it should be, the pathway to diagnosis becomes even more difficult to find. There are families in this region who have been looking for an evaluator for a teenager or an adult for over a year and have not found one.
Rachel got lucky, if fourteen months can be called lucky. She found a provider. She got a date on the calendar. She spent fourteen months watching her son and waiting.
Here is what happens during a fourteen-month diagnostic wait.
The child grows. The brain develops. The window that early intervention research identifies as the period of greatest neuroplasticity, the years when targeted support produces the strongest and most durable outcomes, does not pause for a waiting list.
Rachel spent those fourteen months doing what every family in her situation does: researching, calling, trying. She found a speech therapist who could see Eli after a six-week wait. She found an occupational therapist through a friend of a friend who had a cancellation. She cobbled together a private support network from personal contacts and internet research, because the formal system had told her to wait.
She was fortunate. She had the time, the flexibility, and the social capital to find those providers. She had a partner who could adjust his schedule for appointments. She had a car. She had a job that allowed her enough flexibility that she did not lose it. She knew, because she is a person who knows how to find things, where to look.
Many families in this region do not have those advantages. For them, the fourteen-month wait is not a period of resourceful improvisation. It is fourteen months of nothing, while the window closes.
This is the Silo Tax at its earliest and, in some ways, its most consequential. The cost is not measured in coordination hours yet. Eli isn't in school, doesn't have an IEP, isn't navigating the Medicaid waiver system. The cost is measured in developmental time that cannot be recovered.
Eli's evaluation took three sessions across two weeks. The psychologist was thorough, warm, and clearly gifted with children. The resulting report was forty-two pages long.
Rachel sat in the feedback session and listened to a precise and compassionate explanation of her son. She asked good questions. She took notes. She left with a copy of the report, a diagnosis of Autism Spectrum Disorder, Level 2, and almost no guidance on what to do next.
This is the second failure, and it is the one that surprised her most.
She had spent fourteen months preparing for the diagnosis. She had not understood that the diagnosis itself would open no doors automatically. That the comprehensive evaluation, for all its clinical precision, would land in her hands as a document rather than a referral. That the systems she would need next, the school district, the Medicaid programs, the therapists who specialize in post-diagnostic support, would not know the evaluation existed unless she told them.
There is no formal handoff between a developmental evaluation and the school system in Louisiana. A family receiving a diagnosis from a private psychologist or a hospital system must independently navigate to their school district to request an educational evaluation. IDEA, the federal special education law, requires that evaluation to happen within sixty days of a referral, but the referral must come from the family. No one from EBR Parish Schools called Rachel after Eli's diagnosis. No one from the school district was copied on the report. The clinical system and the educational system exist in parallel universes, and Rachel was expected to build the bridge between them herself.
She did. Because Rachel is Rachel, persistent, resourceful, and unwilling to accept that this was simply how things worked. She called the school district. She requested the evaluation. She waited another eight weeks.
She is aware, with a clarity that comes from living inside this system, that not every family does what she did. That the diagnosis-to-IEP gap swallows children whole. That somewhere in Baton Rouge right now, there is a family that received a report three months ago and is still holding it, waiting for someone to tell them what comes next, because no one has.
Eli is five now. He has an IEP. He has a therapist he adores. He has made progress that his early intervention team describes, carefully, as meaningful.
He also has a mother who has spent three years as the connective tissue between every system that serves him. Who has learned the language of clinical psychology, special education law, Medicaid managed care, and occupational therapy not because she wanted to, but because the systems that should coordinate with each other coordinate through her instead.
The diagnostic wait cost him time no one can give back. The post-diagnosis gap cost her the assumption that the system would respond to her son's needs once it finally knew what they were.
Both costs were preventable. Neither was her fault.
CAAN is building the coordination infrastructure this community needs, not another service, but the connective tissue that allows the systems serving families like Rachel's to communicate with each other. A diagnostic pipeline that moves from evaluation to educational referral without requiring a parent to build the bridge manually. A system that sees Eli's whole story, not just the slice of it that falls within each provider's jurisdiction.
The State of Neurodiversity Report, publishing October 1, will document what this coordination failure costs the Capital Area, in developmental time, in family labor, in long-term outcomes for the children who fall through the gaps during the wait.
If you are a family navigating the diagnostic process right now, if you are Rachel, or if you know her, we want to hear from you. Your experience is the evidence that changes how this system is built.
The CAAN Provider Summit is September 30, 2026. The State of Neurodiversity Conference is October 1, 2026. If you work in diagnostic services, early intervention, or special education in the Capital Area, we want you at the table. Reach out at drew.walker@caanbr.org.
