Steroid receptor coactivator-1: integrating steroid hormone signals to regulate brain function and disease

Steroid receptor coactivator-1 (SRC-1), also known as nuclear receptor coactivator-1 (NCOA1), represents the first identified member of the p160 nuclear receptor coactivator family and plays a pivotal role in integrating steroid hormone signals, regulating gene transcription, and maintaining neural homeostasis in the central nervous system (CNS). SRC-1 exhibits region-specific, cell-type-specific, and sexually dimorphic expression patterns in the brain, with prominent distribution in key regions including the hippocampus, cerebral cortex, hypothalamus, and amygdala. Functional studies demonstrate that SRC-1 participates in diverse neural functions such as learning and memory, energy metabolism, emotional regulation, and reproductive behavior through modulation of synaptic plasticity-related genes, neurotrophic factors, and metabolic pathways. Aberrant SRC-1 expression is closely associated with neurodegenerative diseases, autism spectrum disorders, and glioblastoma. This review systematically summarizes the molecular structure, expression characteristics, physiological functions of SRC-1, and its roles in neurological disorders, while discussing its potential applications as a diagnostic biomarker and therapeutic target.

Autism Screening Proposed for Children with Epilepsy

Children with epilepsy are up to 10 times more likely than others to also have autism, according to research that exposes the scale of the association between the two conditions.

The findings, in more than 30,000 children, stress the importance of screening for developmental concerns among those with epilepsy, so support can be delivered as early as possible.

The study, Developmental Medicine & Child Neurology, revealed that girls with autism spectrum disorder (ASD) were more likely than boys to also have epilepsy.

Higher rates of intellectual disability were also seen in children with autism who additionally had epilepsy, and they were also diagnosed with the neurodiversity at an earlier age.

“Our findings emphasize the importance of screening for autism in this population to support earlier diagnosis and timely intervention, both of which are key to improving long-term outcomes,” said senior investigator Elaine Wirrell, MD, from the Mayo Clinic.

ASD and epilepsy are complex disorders of neuronal connectivity that frequently co-occur because of shared molecular and biological mechanisms.

While the increased risk of ASD in children with epilepsy is well documented, there are gaps in knowledge around its incidence and prevalence, and risk factors for their co-occurrence.

To investigate further, Wirrell and team studied the medical records of 30,490 children in Olmsted County, Minnesota, of whom 257 (0.84%) were diagnosed with epilepsy before the age of 19 years.

They found that children with epilepsy were more likely have ASD across all three research and clinical definitions compared with other children, with this likelihood increased between six and 10-fold.

The prevalence was a corresponding 21.4% versus 3.2% using broad research criteria, 14.0% versus 1.6% across stricter research criteria, and 7.9% versus 0.7% for a clinical diagnosis.

Among children with autism, those also with epilepsy were more likely to have a lower IQ on standardized testing than those in whom epilepsy was absent (56.5% versus 15.4%). Specifically, an IQ of less than 70 was observed in 57.4% of children with co-occurring epilepsy and autism compared with only 15.4% autism alone.

Those with autism and epilepsy were also more often female than those with autism alone (38.2% versus 25.8%), and were identified with autism at a younger age, at a mean of seven years and five months versus eight years and eight months).

“These insights underscore the critical need for comprehensive and early screening protocols to better address and manage the intersection of autism and epilepsy, ensuring timely interventions and tailored support for affected individuals,” the researchers concluded.

Impact of COVID-19 pandemic on autism spectrum disorder service providers in Qatar: challenges, insights, and lessons learned

PurposeThe COVID-19 pandemic disrupted essential services, posing unique challenges for individuals with Autism Spectrum Disorder (ASD) who depend on consistent, specialized support. Service providers faced unique challenges in adapting to remote delivery methods, highlighting the fragility of existing systems during crises. This study explored the experiences of ASD service providers in Qatar during the COVID-19 pandemic.MethodsAn online survey of 66 ASD service providers in Qatar was conducted. Data were analyzed using descriptive statistics, chi-square, and likelihood ratio tests, with qualitative responses assessed through thematic analysis.ResultsMost service providers (90.9%) worked remotely during the pandemic, with 81.8% engaging in online services. Providers reported significant skill regression in individuals with ASD. Stress levels were notably high (42.4%) and significantly associated with emotional tolls [p = 0.017, LR = 4.887], financial strains [p = 0.008, LR = 4.337], and personal challenges [p = 0.008, LR = 3.203]. Thematic analysis revealed decreased therapy effectiveness and difficulties in balancing work with family responsibilities.ConclusionThese findings suggest the importance of adaptive service delivery systems that maintain continuity of care during crises. Strengthening autism service infrastructure and developing resilient models are essential to safeguard autism support for future emergencies.

The long-term psychological processing of an autism spectrum disorder diagnosis in parents

IntroductionA child’s ASD diagnosis represents a critical event for parents, often requiring them to face the loss of their child’s ideal image and reevaluate the family life projects. The aim of this study is to explore how parents retrospectively reconstruct and integrate their child’s ASD diagnosis through autobiographical memories.Methods21 parents, 16 mothers and 5 fathers, that received the ASD diagnosis within five years, were administered the Reaction to Diagnosis Interview (RDI). Interviews were audio-recorded, transcribed verbatim and analyzed using a two levels approach. The first one to explore the patterns of meanings that emerged in the whole parents’ autobiographical memories through the Reflexive Thematic Analysis. The second one is to identify patterns of resolution or non-resolution of the impact of the diagnosis.ResultsFindings show suffering and struggling as main themes and subthemes and a prevalence of unresolved diagnoses; gender differences in the way of managing the child-related care tasks, efforts, and coping strategies emerged.DiscussionIn line with literature, our findings suggest that the availability of supportive resources plays a crucial role in facilitating parents’ adjustment and integration of the ASD experience and harmonizing gender differences. They also emphasize that the impact of ASD diagnosis is not a single event but an ongoing process of meaning-making which changes with the child’s developmental path. Our findings highlight the need for cognitive and emotional reconstruction and reframing of parents’ autobiographical memories. These processes play a kay role in shaping how the diagnosis experience is integrated into one’s narrative identity, creating opportunities for transforming the meaning of the remembered experience.

How to De-Escalate an Autistic Meltdown

A common misconception about tantrums and meltdowns is that they’re interchangeable. But while they share some similarities in their initial expression — crying, screaming, door slamming, harsh words — they’re actually quite different. Dealing with a meltdown requires a more specialized approach, especially with kids on the autism spectrum.

What is a tantrum vs a meltdown?

The two events happen for different reasons. A child throws a tantrum when they’re angry or frustrated, acting out because they feel an injustice has been done to them. They are aware of what they’re doing and still have some sense of control. And if a child’s tantrum is ignored by their parent or caregiver, it will likely subside quickly.

Meltdowns, on the other hand, happen involuntarily and seemingly out of nowhere. They also tend to become much more intense than a typical tantrum and may involve violent behavior such as head banging, hitting others, and damaging property. Once a meltdown has started, intervention is needed to stop it, whether it’s self-imposed (e.g., removing oneself from the trigger) or external (e.g., support from the parent or caregiver). The event can last between a few minutes and several hours.

Tantrums are common among all children, but kids with autism are more likely to experience meltdowns of varying degrees, says Conner Black, PhD, associate director of the Autism Center at the Child Mind Institute.

What are the stages of an autistic meltdown?

For a child with autism, a meltdown is triggered when they become overwhelmed, whether it’s by stress, powerful emotions, sensory input, change, or something else. Their sympathetic nervous system — the network in the body responsible for our “fight-or-flight” response — goes into overdrive and they lose control.

There are several stages to an autistic meltdown and understanding them can help you know how to respond effectively. The duration and intensity of the meltdown depend on whether intervention, including learned coping skills, can stop the child from reaching a crisis point, Dr. Black explains. “Certain skills may not work every time, and that’s really no one’s fault,” he says, but once a child reaches that crisis stage, intervention is no longer useful. He describes the course of a meltdown via the phases of the behavior escalation cycle:

  • Calm: “This is basically the valley or plain on the side of mountain, which is considered the baseline, when the child is happy, relaxed, and at their best,” Dr. Black says. For instance, in a classroom setting, a student’s behavior might be described as cooperative and responsive to instruction. These behaviors are specific to the individual, so it helps to recognize what that looks like in your child.
  • Trigger: While triggers can vary, Dr. Black says, there are some common ones that he typically encounters in kids with autism. “They’re often related to the misunderstanding of social situations, a lack of time to engage with their preferred interests, a sudden change in their schedule, or a transition that was unexpected,” he says. “It could also be certain sensory aversion, so things like loud noises or loud conversations. It could even sometimes be as simple as how food is presented on someone’s plate.” The child’s response to that trigger can vary depending on their current internal state or outside environmental factors. But if the trigger isn’t removed or is strong enough to dysregulate the child, they’re going to enter the next phase: agitation.
  • Agitation: At this point, the child will begin to display behaviors that indicate they are no longer in their calm phase. They might start fidgeting, darting their eyes back and forth, or tapping their hands. For other kids, it could look like total disengagement or staring into space. While removing the trigger might still work at the start of this phase, attempts at problem-solving may backfire and push the child to escalate their behaviors.
  • Acceleration/Escalation: “This is really when you start seeing a ramping up of behaviors,” Dr. Black says. “Anything from screaming to throwing toys to aggressing toward the caregiver or whoever’s in the room. Or they could turn that aggression on themselves, whether that’s head banging or hitting themselves repeatedly.” The child may become resistant to intervention and argumentative.
  • Peak/Crisis: At this phase, the child hasn’t responded to attempts to de-escalate and will continue to engage in potentially dangerous behaviors. “When thinking about the crisis point, I think about behaviors that are often going to require a higher level of care. So that could be violence, self-injurious behaviors, or even intense suicidal ideation,” says Dr. Black. To be able to distinguish between escalation and crisis, he adds, it’s important to know what the top level of your child’s behaviors look like. “Throwing things could be the escalation stage, and then the next stage is actually when they’re destroying property,” Dr. Black explains.
  • De-escalation: Finally, the intensity of the behavior begins to subside. The child may appear disoriented, confused, and tired. They will gradually become calmer.
  • Recovery: The child is officially in this phase when they’re fully back at their baseline, Dr. Black says. The behaviors you’ll see at this phase are the same ones you see when they’re in their calm phase.

How to prevent meltdown escalation

Once a child has started to experience a meltdown, it’s hard to get them back to baseline. Depending on the phase, certain interventions may help while others might make things worse.

First, you want to avoid triggers, Dr. Black advises. “Autistic individuals can have a lot of difficulty talking about or even understanding what their emotions are. So, it’s typically up to the parents or caregivers to identify what things can trigger them in a certain way,” he says.

For instance, some kids with autism really thrive with routine and can become agitated when there are unexpected changes. Having a visual schedule of exactly what’s going to happen during the day can help prevent that, says Dr. Black. “If you know there’s going to be a change, you can pick a time, maybe a couple of days in advance, where you talk to them about what that difference is going to be.”

And if your child is known to have meltdowns in public spaces, says Dr. Black, think about what those outside triggers are and how to prepare ahead of time. If they tend to get upset by loud noises, for example, a pair of headphones can be an item — along with phone, wallet, keys! — that you never leave the house without. If possible, work with a mental health professional to identify triggers and develop an escalation plan. 

What to do in the agitation phase

If your child has reached the agitation phase, says Dr. Black, you can try to intervene with coping skills that you’ve learned in therapy, whether it’s something as simple as removing a trigger or giving them a preferred activity in that moment to help prevent their behaviors from escalating.

Sometimes kids encounter an environment, like school, that is beyond your control but contains a wide range of potential triggers and pushes them into the agitation phase. Because their house is a more comfortable environment, kids with autism may keep themselves together at school and then quickly melt down once they get home.

“In that case, for that first hour, let them have their alone time where they can just chill,” Dr. Black suggests. “It could be eating snacks, watching a TV show, or even just sitting quietly in their room. Maybe it’s engaging in some sort of self-stimming behavior.” This can give them the space to cool down and take some time away from any sort of outside stimuli that could push them to move from the agitation phase into the escalation point of a meltdown.

What to do in the acceleration/escalation phase

It can be hard to anticipate every possible trigger, especially when there might be multiple at once on any given day. And sometimes coping strategies aren’t enough to keep a child from escalating or the trigger is too strong. Still, there are some things that Dr. Black suggests you can do to try to keep them from reaching that crisis point.

Keep communication short and concrete

Too much talking can be overwhelming for the child at this stage and might push them to crisis, Dr. Black explains, so the less communication the better. “A simple instruction looks like using just a short sentence. Say there’s a loud noise, for example. You can just say, ‘Go get your headphones,’” he says.

Use visual prompts

Instead of trying to communicate verbally, you can hold up a visual prompt. “If your child has already been working with a therapist or if they’ve learned some coping skills, it would be helpful to have a laminated sheet readily available with their name and pictures of four different coping skill options — like headphones, deep breathing, coloring, sitting alone in their room.”

Dr. Black advises only giving a few options, as it’s already difficult for the child to focus while they’re upset. Additionally, if they don’t choose one right away and you want to try again, he recommends that you “let there be silence for 60 seconds at minimum between prompts, because you don’t want to over-prompt and exacerbate the situation even more.” But providing these choices allows them to maintain their autonomy, which is important during escalation.

What to do in the peak/crisis phase

“Once they get to that apex, they’ve reached the point of no return and just need to go through the process,” says Dr. Black. He stresses that at this point, communication needs to be very minimal or nonexistent.

When maintaining safety is the focus

“The goal switches to really being able to maintain safety for both the individual as well as the family members in the area,” Dr. Black explains. “If they’re harming themselves, such as head banging, move them to their bed so at least it’s on something that’s softer and not going to potentially cause significant injury.”

Efforts to make sure the child is as safe as possible can put you in harm’s way. “If there’s aggression, you can be watching and making sure they’re safe but not getting too close where you could get aggressed upon,” says Dr. Black.

If there are other children in the house, Dr. Black advises that you make plans for how to keep them safe. “Maybe they can go to their room and lock the door while it’s happening,” he says. “Some families have the other kids go to the car and sit and wait until their parents come out to get them.”

When you need emergency services

If the crisis phase goes on for a long period of time, says Dr. Black, “this is when you’d have to think about calling 911. And as kids become adolescents, the response is going to look a lot different. Because of size alone, it’s a little bit easier to manage the situation in a 5-year-old than it would be in a 15-year-old.”

Dr. Black advises that you get in touch with your local police department or EMT service in advance to let them know you have a child with autism in the home, so if you call during an emergency, they are already familiar with your family.

What to do in the de-escalation and recovery phases

Watch for signs that the child is beginning to de-escalate, Dr. Black says. “All you’re doing at this point is maintaining safety until you’re really able to see a lessening of the intensity of the behavior or the frequency decreases a little bit.” Then, he says, you can start to slowly communicate with them again. You really need to be careful here, because it may look like they’re calming down, but if they’re pushed too hard and they’re not ready to talk, they might go right back into crisis phase.

At the recovery phase, “the whole family is recovering,” Dr. Black says. It’s at this point where you can all debrief and work through what may have triggered this escalation and how to possibly prevent it in the future.

“Make sure you’re also debriefing separately with the other siblings in the home after it happens,” Dr. Black adds. “They’ve just witnessed something that may have been traumatic and really stressful for them. There’s often so much focus given to the child with the big behaviors in the moment.”

Medication treatment

Sometimes, a child or teen may suffer from frequent meltdowns to the point that it’s interfering with their quality of life and their ability to attend school. At that time, a mental health professional may recommend working with a psychiatrist to add medication to their treatment.

The type of medication depends on the underlying mechanisms contributing to the behaviors, Dr. Black says. “For instance, if it’s coming from significant anxiety, psychiatrists may prescribe an SSRI like Prozac or Zoloft. If a child has co-occurring ADHD, which is very common, stimulant or non-stimulant ADHD medication might be recommended. And if the behavior stems from irritability or some kind of rigidity, antipsychotic medications like Abilify or risperidone can be useful.”

Improvement is possible

Dr. Black notes that when kids receive the support they need, their quality of life really improves. “I’ve seen that when families work with therapists to come up with different behavioral plans and figure out a proper medication regimen, there’s a lot of improvement in behavior challenges,” he says. “The duration, frequency, and intensity of the meltdowns decrease as the child learns how to handle strong emotions and parents learn how to respond to them. And the medication can help to increase their likelihood of being able to use coping skills or regulation techniques to calm back down when they start to get really frustrated.”

Auditory processing and communication in autism: exploring verbal abilities and vocal affective cues

This study examined the role of auditory processing in autism spectrum disorder, focusing on its association with verbal and non-verbal vocal communication skills in children and adolescents. A total of 97 English-speaking autistic participants (ages 7.9–17.4 years, mean = 12.3) and 44 neurotypical peers (ages 8.4-16.8, mean= 12.3) completed assessments of auditory processing and communication skills. We analyzed the relationships between scores on the SCAN-3 Tests for Auditory Processing Disorders time-compressed sentences, auditory figure-ground (+ 8dB), gap detection, and competing words-free recall subtests, the Clinical Evaluation of Language Fundamentals-Fifth Edition (CELF-5) expressive and receptive language indices, the Goldman-Fristoe Test of Articulation-3rd Edition (GFTA-3) Sounds-In-Words subtest, and the Diagnostic Analysis of Nonverbal Accuracy-2nd Edition (DANVA-2) paralanguage subtests. Measures of auditory processing were associated with both verbal and non-verbal communication skills in the autistic participants. Specifically, we found that SCAN-3 time-compressed sentence and gap detection scores were associated with expressive and receptive language skills, receptive vocabulary scores, and ability to recognize vocal emotional cues. Gap detection abilities additionally correlated positively with expressive and receptive language skills, while auditory figure-ground task performance was related to articulation. In conclusion, this study suggests specific aspects of auditory processing may be important for development of specific aspects of auditory communication skills in children on the spectrum. Specifically, spectral aspects of auditory processing abilities were associated with articulation accuracy whereas temporal components of auditory processing may impact broader verbal and nonverbal communication skills. Further research is needed to better understand the underlying mechanisms of these associations and potential directions of causality to inform development of interventions that target auditory processing and auditory communication skills in ASD.
