Autism is remarkably heterogeneous, posing a long-standing challenge for linking genetics to brain dynamics. A cross-species study identifies two principal dysconnectivity signatures across 20 mouse models of autism risk, each associated with distinct molecular pathways, and shows analogous connectivity patterns in autistic humans. These results establish a translational framework for biologically grounded fMRI phenotyping.
Pagani et al. used cross-species fMRI to reveal two autism subtypes, characterized by lower and higher brain connectivity and linked to synaptic and immune-related pathways, respectively.

IntroductionIn Western countries, autism diagnoses are increasingly assigned in the first years of life. But is earlier necessarily better? Despite potential benefits, autistic infants and toddlers cannot participate in these discussions. In the ethical debate on early autism diagnosis, this raises tensions between parental duties and rights, and the child’s developing autonomy.MethodsTo mend the lack of autistic voices in this debate, we queried a diverse group of 18 autistic adolescents (aged 16–18). In a set of indepth interviews, we explored their experiences of their autism diagnosis, and their views on the ideal timing of such a diagnosis, if at all.ResultsUsing the QUAGOL data-analysis method, we developed three themes: (1) (Not) feeling different, (2) Drawing up the balance of the label’s value, and (3) Getting the timing right. Adolescents experiencing most difficulties in navigating the neurotypical world also seemed to value the diagnostic label most, and vice versa. Nevertheless, nearly all adolescents favored a relatively early diagnosis and early disclosure thereof—not necessarily in infancy, but early enough to enable timely support for both themselves and their parents. Crucially, adolescents emphasized that such early support should be personalized, readily available and neurodiversity-affirmative to make early diagnosis truly worthwhile.DiscussionOur data did not corroborate any presumed clash of interests between parents and autistic children. Consequently, we suggest moving this ethical debate away from a discourse based on individual rights or interests toward a relational, care ethics approach.
Numerous neuropsychiatric disorders frequently exhibit overlapping genetic risk factors, implying the molecular basis for their comorbidity. Nevertheless, the pathogenesis of these disorders remains elusive, particularly regarding how genetic variations impair the physiological function of risk genes and contribute to disease phenotypes. Neurexin 1 protein, encoded by NRXN1 gene, belongs to the neurexin family of presynaptic adhesion molecules. And neurexin 1 is involved in synaptogenesis and the maintenance of synaptic action. Genetic variations of NRXN1 have been demonstrated to be associated with a spectrum of neuropsychiatric disorders. Herein, this review focuses on the most recent and relevant literature concerning the genetic and molecular mechanisms through which NRXN1 variants contribute to the pathogenesis of neuropsychiatric disorders, particularly schizophrenia and autism spectrum disorder. Among them, we propose the isoform-dependent excitation-inhibition imbalance hypothesis of NRXN1 in autism spectrum disorder. And this hypothesis may account for both the elevated and decreased excitation-inhibition ratios observed in diverse individuals with autism spectrum disorder. Moreover, both schizophrenia and autism spectrum disorder involve deletions and alternative splicing of NRXN1, offering molecular evidence for their comorbidity. Then, we analyzed and summarized the current research status of NRXN1 in other neuropsychiatric disorders, including attention-deficit hyperactivity disorder, insomnia, epilepsy, suicide, and depression. Additionally, available limited researches on NRXN1-targeted therapeutic strategies and associated pharmacological studies are also incorporated. Finally, we discussed existing challenges in NRXN1 research within the context of neuropsychiatric disorders and proposed potential avenues to overcome these obstacles.
Every day, parents reach out to the Child Mind Institute with questions that keep them up at night: Why does my daughter have such strong emotions? Why can’t my son sit still in class? Is this normal anxiety or something more?.
These questions are urgent, but finding answers isn’t easy. The wait time to see a children’s mental health professional can be months or even years. Many families don’t know where to start, what’s normal for their child’s age, or whether their concerns warrant professional help. And with nearly 1 in 5 children experiencing a mental health challenge within the U.S. alone, too many families are navigating this uncertainty on their own.
That’s why we built Ask Kai — a free, evidence-based symptom checker designed specifically for children’s mental health, available in both English and Spanish.
Meet Ask Kai
Ask Kai is a conversational symptom checker that helps parents and caregivers understand their child’s behavior and points them to appropriate resources. Through a streamlined series of questions and prompts, Ask Kai gathers information about your child’s challenges and provides personalized recommendations in minutes.
Ask Kai doesn’t diagnose your child. Instead, it helps you:
Understand whether your concerns align with common mental health challenges
Learn what to look for and what questions to ask
Find evidence-based resources specific to your child’s needs
Know how to find additional support if needed
Think of Ask Kai as a knowledgeable guide who helps you make sense of what you’re seeing and points you toward your next best step.
How Ask Kai works
If you’ve ever used a symptom checker for physical health, you know the challenge: enter “headache,” and you might walk away convinced you have everything from a sinus infection to a brain tumor. Mental health symptom checkers face even greater challenges. Because every child is different, what looks like defiance in one child could look like anxiety in another, and a behavior that’s appropriate at age five might be cause for concern at age ten. On top of that, mental health conditions often overlap.
So how did we build a tool that captures this complexity without overwhelming families? We focused on expertise and evidence:
Clinicians and data lead the way: Ask Kai was built using thousands of child mental health evaluations — open datasets spanning different ages, backgrounds, and conditions — and developed in close collaboration with child psychologists and psychiatrists.
Evidence-based question selection: Rather than asking hundreds of questions, we used machine learning to identify which combinations of questions provide the most meaningful information without burdening families.
Comprehensive resource library: Every recommendation Ask Kai makes is matched to our extensive collection of guides, articles, expert perspectives, and pathways to professional help.
Here’s what happens when you use Ask Kai
Step 1: Initial Screening
You’ll answer a brief set of questions about your child’s behavior, emotions, and how these challenges affect daily life. You’ll also have the chance to describe in your own words what brought you to Ask Kai. These questions cover the areas where we see the most common concerns.
Step 2: Personalized Deep Dive
Based on your responses, Ask Kai selects targeted follow-up questions that dig deeper into the areas you flagged, whether that’s attention and focus, social anxiety, learning, or other behavioral challenges.
Step 3: Matching You to Resources
Ask Kai analyzes your complete response pattern, including the severity and impact of the behaviors you described, and provides a report with recommendations relevant to your child’s age, challenges, and needs.
What Ask Kai can assess
We designed Ask Kai to explore the areas where we can provide the most help to the most families. Ask Kai offers comprehensive screening and resources for:
ADHD (Attention-Deficit/Hyperactivity Disorder)
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that is characterized by difficulties with attention, organization, and impulsive behaviors. Symptoms are usually divided into inattentive behaviors or hyperactive and impulsive behaviors. Inattentive symptoms may include making careless mistakes, being easily distracted, difficulty listening to instructions, trouble with organization, and forgetfulness. Hyperactive/impulsive symptoms may include fidgeting or squirming, trouble playing quietly, extreme impatience, as well as constant talking and interrupting.
Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that begins in utero, but children may not get diagnosed until they’re in preschool or even older, when symptoms become more apparent. The disorder is characterized by deficits in social communication skills as well as restrictive or repetitive behaviors. Symptoms include a wide range of impaired cognitive abilities, language skills, and behaviors. These symptoms have been thought of as a set of disorders but are now being considered one disorder that presents along a spectrum.
Depression
Depression is a mood disorder that can cause children and teenagers to feel very sad and hopeless. Kids with depression have trouble enjoying things they used to love. They may also seem listless and easily annoyed.
Generalized Anxiety Disorder
Generalized anxiety disorder is characterized by excessive, persistent, and unreasonable worries about everyday things, like doing well in school or sports. In general, kids with this disorder worry a lot about being perfect.
Oppositional Defiance Disorder
Oppositional defiance disorder is a disruptive behavior disorder characterized by ongoing persistent, age-inappropriate disobedience and resistance to authority. To be diagnosed with this disorder, children would have had to display extreme behavior issues for at least six months. Diagnosis occurs around early elementary school ages and stops around adolescence.
Social Anxiety Disorder
Social anxiety disorder is a type of anxiety characterized by such intense self-consciousness and fear of embarrassment in social situations that the individual avoids social events; also known as social phobia. While some kids with this disorder are specifically afraid of performance engagements like public speaking or sporting events, others are scared of general social situations.
Specific Phobia
Specific phobia is an anxiety disorder characterized by an excessive and irrational fear of an object, situation, or place. Common specific phobias include dogs, clowns, bugs, the dark, and loud noises.
Elimination Disorders (Enuresis & Encopresis)
For young children, bathroom troubles are often a normal part of growing up. But once kids pass potty-training age, peeing or pooping in places other than the toilet might be a sign of an underlying issue. If it involves urine, it’s called “enuresis.” If it involves feces, it’s called “encopresis.”
Nonverbal Learning Disorder (NVLD)
Nonverbal learning disorder (NVLD) is a condition characterized by difficulty processing visual-spatial information — which involves the brain’s ability to interpret and respond to visual input, including where things are in space. These skills are used to do things like putting together a puzzle or reading a diagram.
Specific Learning Disorder (Dyslexia, Dyscalculia, & Dysgraphia)
Specific learning disorder is a condition that causes children to have difficulty with reading, writing, and/or math. If they have trouble with reading, the disorder is called dyslexia. If they have trouble with writing, it’s called dysgraphia. If they have trouble with math, it’s called dyscalculia. Symptoms are typically first noticed when the child is in preschool or early elementary school.
These ten areas represent some of the most common mental health concerns in childhood. They’re also areas where we have robust data, validated assessments, and comprehensive resources.
What if your concerns aren’t on this list?
Ask Kai can still help. When you describe your situation in your own words, Ask Kai analyzes your response to identify additional concerns and match you to appropriate resources. Your child’s challenges don’t need to fit neatly into one of these categories for Ask Kai to provide value.
However, we will only make recommendations when we’re confident in the evidence behind them. If a particular concern isn’t well represented in our data, we won’t try to provide guidance in that area. Regardless of the results, everyone receives a core set of resources that we believe are helpful for all families navigating children’s mental health.
