Autism spectrum research — NIH Funding Overview

Why this matters now

Autism prevalence estimates have continued to rise (CDC 2023 update: 1 in 36 8-year-olds), increasing pressure for research on early identification, services for adults, and underserved populations. Lifespan-focused funding has grown significantly relative to the historical pediatric concentration.

How NIH funds this area

Mechanisms include R01, P01, P50 (Autism Centers of Excellence), R21, and K-series career awards. The Autism Centers of Excellence (ACE) network is a flagship program at NICHD/NIMH. Data below covers all NIH awards mentioning autism in title, abstract, or terms.

What the data shows

• Funding peaked in FY2025 at $971M. The FY2025 total of $971M is +13% versus FY2021.
• The number of awards fell about 7% in FY2025 even as total dollars grew — funding is concentrating in fewer, larger awards.
• About 82% of FY2026 dollars so far are non-Type-1 award actions, including competing renewals, supplements, non-competing continuations, and institutional changes. This is a descriptive record mix, not a measure of renewal activity alone.
• The average FY2025 award was $623K, and R01 was the most common mechanism in the recent window.

• Scalable functional analysis of neuropsychiatric risk genes with spatially integrated in vivo Perturb-seq

  5R01MH137042-03
  Xin Jin · SCRIPPS RESEARCH INSTITUTE, THE, CA · $890,929 · awarded Aug 28, 2026 · R01

  Although numerous genes and loci associated with autism spectrum disorder and neurodevelopmental delay (ASD/NDD) have been identified through genome sequencing efforts, the precise mechanisms by which most of these genetic variants lead to the condition remain largely unknown. We propose to combine high-content in vivo genetic screening with whole brain…

• 1/3 Akili: Phenotypic and genetic characterization of ADHD in Kenya and South Africa

  5R01MH132968-04
  Elise Robinson · BROAD INSTITUTE, INC., MA · $646,978 · awarded Aug 28, 2026 · R01

  ADHD is a common neurodevelopmental disorder that includes attention difficulty, impulsivity, and hyperactivity. The diagnosis is associated with many challenges to educational, occupational, and health outcomes, particularly when untreated. Genetic studies of ADHD have the potential to clarify the disorder’s biological underpinnings, its heterogeneity, and…

• Sleep-driven reorganization of excitatory and inhibitory synaptic nanoarchitecture

  1R21NS151357-01
  Michelle Bridi · WEST VIRGINIA UNIVERSITY, WV · $420,750 · awarded Aug 27, 2026 · R21

  PROJECT SUMMARY/ABSTRACT Sleep loss is a prevalent problem that is caused by many environmental, social, and health factors. In particular, sleep disruption is common in many neurological conditions, ranging from neurodevelopmental disorders to neurodegenerative disease. However, our understanding of the role of sleep loss in these conditions is limited…

• Balancing flexibility and stability during learning and task switching

  1R01MH141757-01
  Marlene Cohen · UNIVERSITY OF CHICAGO, IL · $656,448 · awarded Aug 27, 2026 · R01

  PROJECT SUMMARY Adaptive behavior requires cognitive flexibility in an environment that is largely, but not always stable. The brain must balance flexibility and stability in the routing of sensory and contextual information to guide actions. Deficits in this balance are hallmarks of disorders ranging from dementia to autism to substance abuse. Although…

• Pediatricians Empowering Parents (PEP) Talk: Creating A Ripple Effect in Primary Care to Facilitate Access to Early Intervention and School-Based Services for Children with Autism

  1R01MH142548-01
  Robin Kochel · BAYLOR COLLEGE OF MEDICINE, TX · $406,445 · awarded Aug 26, 2026 · R01

  PROJECT SUMMARY/ABSTRACT Early intervention is critical to improving behavioral health outcomes for children with autism spectrum disorder (ASD). However, more than 50% do not receive mandated early childhood intervention (ECI), which may delay receipt of subsequent school-based services (SBS), particularly in communities with limited access to healthcare.…

• Studying FXS-associated Hypervascularization and BBB Defects Using BBB Assembloids: Unveiling the Underlying Molecular Mechanisms

  1R01MH139612-01A1
  Ziyuan Guo · CINCINNATI CHILDRENS HOSP MED CTR, OH · $723,817 · awarded Aug 26, 2026 · R01

  Fragile X Syndrome (FXS) is a leading monogenic cause of autism spectrum disorder (ASD), resulting from CGG repeat expansion-mediated silencing of the FMR1 gene and subsequent loss of Fragile X Mental Retardation Protein (FMRP). Recent studies implicate brain vascular and blood-brain barrier (BBB) abnormalities—factors that remain underexplored in ASD/FXS…

• Reconstructing the Maternal-Fetal Interface: A Placenta–Brain Axis on a Chip Platform to Transform Models of Prenatal Neurotoxicity

  1DP2ES039816-01
  Melissa Campbell · UNIVERSITY OF CALIFORNIA, SAN DIEGO, CA · $760,000 · awarded Aug 26, 2026 · DP2

  Project Summary: Environmental exposures during pregnancy including pesticides, air pollutants, and common medications are among the most potent yet least understood drivers of adverse neurodevelopment. Epidemiological studies consistently link such exposures to disorders such as autism, ADHD, and schizophrenia, but the mechanistic pathways connecting…

• Neurogenomic Investigations of Trichotillomania and Excoriation Disorder

  5K08MH128665-05
  Emily Olfson · YALE UNIVERSITY, CT · $193,860 · awarded Aug 26, 2026 · K08

  PROJECT SUMMARY/ABSTRACT Trichotillomania (hair pulling) and excoriation (skin picking) disorder are debilitating, difficult-to-treat obsessive-compulsive disorder (OCD) spectrum conditions with no first-line pharmacologic interventions. Previous work supports the role of shared genetic factors in the development of these body-focused repetitive behaviors…

• Uncovering the dynamics and regulatory logic of cell fate specification in cerebral organoid data

  5R01NS139561-07
  Smita Krishnaswamy · YALE UNIVERSITY, CT · $537,197 · awarded Aug 25, 2026 · R01

  A deep understanding of the gene regulatory logic that controls human brain development is essential for un- covering the mechanisms of neurodevelopmental disorders and designing treatment protocols. Here, we com- bine cortical organoids, single cell CRISPR screens, spatial transcriptomics and metabolomics with a suit of state-of-the-art computational…

• Protracted Maturation of Cortical Inhibitory Neurons for the Complexity of Higher Cognitive Areas

  5K99NS138587-02
  Jaeyeon Kim · UNIVERSITY OF CALIFORNIA, SAN FRANCISCO, CA · $115,487 · awarded Aug 21, 2026 · K99

  Neurodevelopmental mechanisms in the human brain have emerged to support its larger size, increased complexity, and higher cognitive functions. Despite these benefits, the human brain encounters a variety of risks during development that can lead to developmental disabilities such as autism spectrum disorder (ASD). This evolutionary paradox has prompted a…

• Promoting Early Engagement, Relationships, and Socialization (PEERS)

  1R01DC023445-01A1
  Laura Justice · OHIO STATE UNIVERSITY, OH · $686,822 · awarded Aug 21, 2026 · R01

  The goal of the proposed randomized controlled trial is to evaluate the impacts of the Promoting Early Engagement, Relationships, and Socialization (PEERS) intervention on the language and social experiences and skill development of young children with developmental language disorder (DLD). PEERS is a peer-mediated intervention designed to help children…

• Synaptic Organization and Modulation of Kainate Receptors: Investigating the Structure, Dynamics, and Function in the Context of Trans-Synaptic Junctions

  4K00NS130928-03
  Cuauhtemoc Gonzalez · RUTGERS, THE STATE UNIV OF N.J., NJ · $93,541 · awarded Aug 21, 2026 · K00

  Abstract Kainate receptors are members of the ionotropic glutamate receptor family and are implicated in epilepsy and in multiple neurocognitive deficits such as autism, schizophrenia, and mental retardation. These receptors can be found to express in the presynaptic membrane where they regulate neurotransmitter release and postsynaptic membrane where it is…
