Dara S. Manoach, Ph.D., discusses research updates on autism and sleep. She outlines aspects of a good night’s sleep and emphasizes the role of sleep cycles in cognition, memory, and learning. The speaker considers how to treat neurodevelopmental disorders by targeting sleep spindle rhythms which affect thalamocortical neuronal loops, essential to memory and attention. Manoach outlines how spindle rhythms correlate to memory consolidation during sleep in schizophrenia and autism, and highlights technological advancements that allow for broader sample sizes and more accessible studies. The presenter notes potential treatment goals and ongoing research before the Q&A.

A good night’s sleep

Manoach explains that a night’s sleep is divided into REM and non-REM cycles, with non-REM further divided into three stages based on slow-wave activity. The speaker’s research focuses on non-REM Stage 2 sleep, which occurs in the early morning and is characterized by sleep spindle brain rhythms (1:15). Manoach considers how sleep affects cognition, highlighting that critical aspects of learning and memory occur during sleep (2:15). She cites ancient references to the interaction of memory and sleep (Quintilianus, 95 AD) and highlights a 2001 study that kicked off the current explosion in sleep and memory research (3:10). 

• Sleep, Learning, and Dreams: Off-line Memory Reprocessing (Stickgold et al., 2001)

Sleep, memory, and learning

The presenter cites studies showing that sleep prioritizes memory for emotional information and helps extract the main point of an idea or experience. Sleep also increases spatial navigation and facilitates language learning in infants (4:25). The speaker asserts that this body of work has led to a paradigm shift in understanding sleep as an active period of cognitive functioning that facilitates learning and memory (6:00). 

• The role of sleep in declarative memory consolidation: passive, permissive, active or none? (Ellenbogen et al., 2006)
• Sleep Preferentially Enhances Memory for Emotional Components of Scenes (Payne et al., 2008)
• Dreaming of a Learning Task Is Associated with Enhanced Sleep-Dependent Memory Consolidation (Wamsley et al., 2010)
• Sleep inspires insight (Wagner et al., 2004)
• The Sleeping Infant Brain Anticipates Development (Friedrich et al., 2017)

The speaker describes finger-tapping motor sequence tasks (MST) in which participants use a keyboard to type a number sequence as quickly and accurately as possible. The following day, they complete the MST again to test learning improvements after a night of sleep (6:40). Research shows significant improvement in MST results after 12-hour intervals with a sleep sequence (7:45). Time of MST training (10 AM vs 10 PM) did not affect following day outcomes, and a 12-hour interval with no sleep cycle did not yield performance improvements (8:15). These findings, Manaoch asserts, emphasize the critical role of sleep in memory and learning. 

• The acquisition of skilled motor performance: Fast and slow experience-driven changes in primary motor cortex (Karni et al., 1998)
• Practice with Sleep Makes Perfect (Walker et al., 2002)

Sleep spindles and memory consolidation

MST studies in people with schizophrenia show a normal amount of learning during training. However, after a night of sleep, MST performance did not significantly improve, meaning that individuals with schizophrenia do not get the same benefits from sleep as their peers (9:23). The speaker notes that this failure of overnight improvement occurred in the context of significantly reduced sleep spindles, which are a critical mechanism of memory consolidation (10:00). Manoach states that memory consolidation deficits are also characteristics of autism, though the link has been better established in schizophrenia literature (12:17). 

The presenter outlines her research model, highlighting the importance of forging empirical links in causal chains across genes, circuits, physiology, cognition, diagnosis, and treatment (13:04). She describes brain spindles as a rhythm of Stage 2 non-REM sleep, which is recorded on an EEG as one-to-two-second bursts of brain activity. Spindles are initiated in the thalamus and sent to the cortex via thalamocortical neuron loops (e.g., bursts of brain activity), regulated by the thalamic reticular nucleus (TRN). The TRN is essential for sensory gating, or filtering out sensory inputs. Manoach asserts that spindle deficits in schizophrenia suggest a problem in this circuitry related explicitly to TRN modulation (12:50). 

• A failure of sleep-dependent procedural learning in chronic, medicated schizophrenia (Manoach et al., 2004)
• Reduced Sleep Spindles and Spindle Coherence in Schizophrenia: Mechanisms of Impaired Memory Consolidation? (Wamsley et al., 2012)

She cites research showing that dysfunctional thalamocortical circuitry can lead to attention fragmentation and impaired sensory gating in schizophrenia (14:30). Studies also show hyperconnectivity between the thalamus and motor sensory cortex associated with spindle deficits. Therefore, she asserts that research to date suggests decreased spindles and increased connectivity reflect the same thalamocortical circuit dysfunction in schizophrenia (16:00).

Genetic underpinnings

Manoach cites two animal model studies that found spindle deficits in mice with schizophrenia risk gene CACNA1I. Spindle deficits were correlated with reductions in thalamocortical circuitry (17:30). The speaker explains that autism risk genes, like PTCHD1, are also implicated in TRN dysfunction and have been correlated with spindle reduction and reduced visual gating leading to fractured attention in animal models. These data, she asserts, directly link gating issues to attention deficits and spindle dysfunction (19:40). She explains how TRN mutations in early development can predispose individuals to neurodevelopmental conditions like autism (21:15). 

• A rare schizophrenia risk variant of CACNA1I disrupts CaV3.3 channel activity (Andrade et al., 2016)
• Effects of a patient-derived de novo coding alteration of CACNA1I in mice connect a schizophrenia risk gene with sleep spindle deficits (Goshal et al., 2020)
• Thalamic reticular impairment underlies attention deficit in Ptchd1Y/− mice (Wells et al., 2016)
• New views of the thalamic reticular nucleus in the adult and the developing brain (Mitrofanis & Guillery, 1993)
• Early motor activity drives spindle bursts in the developing somatosensory cortex (Khazipov et al., 2004)

Sleep in autism

The presenter explains that 80% of autistic children experience sleep disturbances, which can exacerbate symptoms and impact daily function. She outlines a recent home-sleep EEG study that revealed autistic people had worse sleep quality than their non-autistic counterparts, specifically related to sleep latency, sleep efficiency, night wakings/arousals, and percentage of time in non-REM Stage 1 sleep (22:20). The same study also found reduced spindle rates in Stage 3 non-REM sleep and reduced thalamocortical coordination, with later and more variable spindle peaks compared to controls (24:00). These data, Manoach explains, are consistent with disruption to TRN during sleep. She hypothesizes that, as in schizophrenia, there is less gating of auditory information due to TRN deficits in autism (26:00).

• Increased resting-state thalamocortical functional connectivity in children and young adults with autism spectrum disorder (Baran et al., 2022)

Sleep-dependent memory consolidation in autism

The presenter notes that MST studies in autism do not report deficits in sleep-dependent memory consolidation. Where typically developing individuals had normal spindle count, autistic participants showed an inverse number comparatively (27:00). Manoach considers the role of spindles if not memory. She posits that they may support overall sleep cycles and, therefore, spindle deficits may contribute to sleep disruption in autism (28:00). 

• Dyscoordination of non-rapid eye movement sleep oscillations in autism spectrum disorder (Mylonas et al., 2022)

Ongoing work

Manaoch’s ongoing work looks at the links between sleep disruption in autism and spindle deficits, circadian disruptions, thalamocortical circuit function (gating), EEG abnormalities, and relations to sensory sensitivities. She notes a pilot study on the physiological effects of melatonin (29:00). The speaker considers the issue of small sample sizes in sleep analysis and explains how they are scaling up research with a wearable sleep headband that can be used at home, making sleep studies more accessible (30:00). 

She outlines part of her lab’s work with closed-loop auditory stimulation (CLAS) during a nap, monitored by EEG (31:45). Results show that CLAS has a strong effect on slow-wave and sigma rhythms, but it did not lead to better memory in this study. However, researchers now posit that timing matters (32:45). Manoach explains that the closer CLAS occurs to a sleep upstate, the more likely it is to evoke a slow-wave and spindle creation (33:30).

Accessibility and large sample sizes

The speaker reiterates the usability of the new sleep headbands and discusses their ongoing piloting process spanning the entire U.S. (35:15). She notes experiment preparation, procedures, and support, emphasizing the accessibility of participating from home (35:55). Preliminary data show no spindle deficits in non-REM Stage 2 or Stage 3 as a whole. However, when assessed by sex, spindle deficits are constrained to males. Manaoch considers whether other inconclusive studies have considered sex and how results may differ if they had (36:30). She notes that spindle deficits have been observed in studies with only male participants and speaks to the importance of large, diverse sample sizes. The presenter notes that study protocols and tools have been adapted for those with profound autism, citing the lack of studies in this group and the need for broader samples (37:50). She briefly describes ongoing sleep biomarker studies and outlines potential treatment goals (40:25): 

• Correct thalamocortical circuit function
• Increase spindles or improve coordination 
• Improve sensory gating
• Restore sleep
• Support the daily life of those with autism and their caregivers

Manoach thanks and acknowledges her research team and funders (41:40). She highlights that her lab is actively recruiting participants for one of the sleep studies discussed and provides her contact information before the Q&A (43:15).

Sleep cycles and circadian rhythm

Kobliner outlines recommended sleep times (total length of sleep) for different age groups and notes that lack of sleep leads to impulsivity, attention deficits, forgetfulness, learning deficits, obesity, impaired immune function, anxiety, and depression in both children and adults (2:30). Circadian Rhythm, the speaker continues, is a cycle maintained by the body that influences the balances of cortisol and melatonin throughout the day. She highlights that healthy sleep patterns, or balanced cortisol and melatonin cycles, are associated with benefits to mental health, cognition, and development (5:36). 

How lifestyle affects sleep cycles

The speaker discusses several aspects of lifestyle and how they affect sleep patterns. For example, you must decrease your core temperature by two or three degrees to initiate and maintain sleep. Kobliner suggests taking a hot shower 60 – 90 minutes before bed or wearing socks to sleep to support radiation of heat through the extremities, thus cooling the body (7:36). Upon entering sleep, she continues, cortisol levels should be at their lowest, so winding down before bed is important (8:40). Some common techniques for winding down include avoiding electronics one to two hours before bed, stretching/relaxing body movements, and meditation (10:20). Kobliner discusses the correlation between gratitude journals and sleep quality, noting that research shows a 50% decrease in sleep onset in those who journal (11:30). 

To ensure sleep-supportive lighting, the presenter suggests avoiding LED, dimming the lights an hour or so before bed, using sleep masks, and eliminating blue wavelength light (from screens), which shuts off melatonin production (12:00). Kobliner recommends not eating within three hours of sleep to regulate body temperature and emphasizes the importance of consistent bedtimes (13:40). Exercise should be done earlier in the day and not less than 2 hours before bed because it can raise cortisol levels and increase core temperature (14:40). The presenter notes typical consequences of sleep obstruction including apnea, snoring, daytime fatigue, and attention deficit, among others (15:20). 

How nutrition affects sleep cycles 

Kobliner outlines research showing that a lack of crucial nutrients like calcium and magnesium, as well as vitamins A, C, D, E, and K, are associated with sleep problems. Nutrient consumption affects circadian hormonal pathways, making diet a critical aspect of balanced sleep cycles (16:20). Carbohydrates support melatonin production but can also increase time to sleep and drowsiness. Therefore, the speaker states, carbs should be consumed three to four hours before bed and should be whole grain, not processed (18:10). Calcium is necessary to convert tryptophan to melatonin and can be found in dairy, boned fish, almonds, broccoli, and sesame seeds. Deficiencies in vitamin D, which can be absorbed from sunlight, egg yolk, and fatty fish, are linked to insomnia (20:28). 

The presenter explains that magnesium supports neurotransmitter production, reduces restless leg syndrome, makes it easier to fall asleep, and improves sleep quality. Good sources of magnesium include leafy greens, nuts, seeds, whole grains, and soy (21:30). Vitamins B6 and B12 are necessary for melatonin production. Kobliner emphasizes balanced vitamin B levels, highlighting that deficiencies are linked to insomnia and depression while high doses are not safe. Sources for B6 include bananas, carrots, spinach, potatoes, eggs, fish, whole grains, milk and cheese. B12 can be absorbed from dairy, eggs, meat, fish, and shellfish (22:45). 

Amino acids are proteins’ building blocks, and some are critical to sleep. For example, tryptophan turns into serotonin, which ultimately turns into melatonin. Therefore, Kobliner asserts that we need to support this pathway with the food we eat. She lists some foods that support healthy sleep, including eggs, fish, peanuts, pumpkin seeds, tofu, and more (23:49). All of these foods are highlighted in the Mediterranean diet, which the speaker repeatedly notes as supportive of sleep. Other crucial amino acids include GABA and L-TEHTANINE, which work together to reduce anxiety, time to sleep, and overall sleep quality (25:49).

Herbs and supplements for sleep

Kobliner outlines potential melatonin doses and comments on its long-term use (26:45). She lists herbs and supplements that support sleep, noting specific qualities for each: valerian (28:40), lemon balm (29:09), Zyziphus (jujube) (30:08), passion flower (30:45), chamomile (31:15), skullcap (31:44), and lavender (32:20). 

Adaptogens are compounds that help our bodies deal with stress (33:46). Stress medications are often one way, meaning they reduce stress but then may keep the stress response from acting appropriately overall. However, adaptogenic herbs support and improve the body’s stress resilience and, because stress induces cortisol production, positively affect sleep cycles and quality (34:45). Kobliner highlights three adaptogenic herbs and their benefits to sleep: Rhodiola, ashwagandha, and holy basil (tulsi) (35:00). 

The speaker summarizes her presentation, reiterating the importance of circadian rhythm and balanced cortisol and melatonin cycles. She reminds viewers that poor sleep affects everything from energy to blood sugar to hormonal balance. Lifestyles, including diet, should aim at reducing stress and modulating cortisol to enhance sleep onset, duration, and quality. She notes that all of this can seem overwhelming and recommends starting with the “low-hanging” fruit or changes that are easier to implement (e.g., electronic schedules, bedtime snacks, adding protein to the diet) (36:18). During the Q&A the speaker discusses sources for essential nutrients, strategies for relaxing before sleep, and much more (37:40).

Contributors to insomnia

Malow emphasizes the overlap of biological, behavioral, and medical contributors to insomnia (3:03). Although her presentation focuses on autism and neurodevelopmental disorders, she explains that the information provided pertains to all children and adults (4:30).

Genetic factors

Clock genes are the genes that contribute to circadian rhythm, or our biological clock. These genes regulate our sleep-wake cycles and how we function throughout the day (6:45). Malow outlines a 2017 review where two studies showed abnormalities in the circadian rhythm genes in autistic participants. These studies underscore the substantial role that genetics play in sleep issues, especially in autism (5:00). 

Medical factors

Medical conditions that contribute to sleep issues include sleep apnea, seizures, GI issues, and some medications (7:35). The speaker describes how researchers assess sleep issues using polysomnography. She emphasizes that because observations are recorded in a lab, they cannot evaluate regular sleep cycles. Therefore, researchers use polysomnography to assess whether physical sleep abnormalities like breathing problems or seizures are present (8:00). Malow explains sharp wave activity and how to read tracings for seizures and sleep apnea and highlights the importance of a family-centered approach to sleep assessments (10:00). 

Other forms of sleep and insomnia observations involve using a Fitbit-like watch to track standard sleep patterns across weeks or months (10:45). Malow explains how to read sleep-wake pattern results and notes that such technology is also available in a tight-fit t-shirt for those with sensory sensitivities (11:15). 

Behavioral factors

Common behavioral contributors to sleep issues include limited physical exercise, diet and nutrition, screen time routines, early bedtimes and wake times, and sometimes parental stress. The speaker emphasizes that parent and child sleep cycles impact one another (12:20). She asserts that treatments for insomnia should focus on behavioral approaches and outlines the Family Inventory of Sleep Habits (FISH), which observes daily diet, exercise, routines, and more (14:08). 

Behavioral treatment strategies

Malow suggests using calendars or picture displays of bedtime routines to create a supportive sleep environment and minimize sleep latency, or the time it takes to fall asleep. She provides links to free toolkits, resources, and other materials (14:53). A 2016 study employed a sleep education program for adolescents and teens who may receive different attention and care than younger children. Participants experienced improved sleep latency, efficiency, and duration after only two or three sessions (15:30). The speaker reiterates the importance of sleep cycle management across the lifespan. 

Pharmacological treatment strategies

Pharmacological treatments are best used only after behavioral therapies have been tried and were unsuccessful. It is also critical, Malow continues, to assess any co-occurring conditions, including medical conditions and mental health (17:00). She urges viewers to be careful about starting any medication for sleep (even over-the-counter). She insists that a general practitioner is involved in the process (18:00). 

Melatonin is one of the most commonly used medications for sleep. While standard pills only help with falling asleep, new prolonged-release melatonin shows great promise for reducing night wakings (18:45). The speaker outlines an extended-release melatonin study of 125 children (ages 2 – 17.5). Results were promising, with participants reporting that, on average, sleep latency decreased by 25 minutes and sleep time increased by 32 minutes (20:10). 

Malow discusses clonidine use, noting the long list of side effects and the need for more studies (20:30). Gabapentin is another common medication that has been found to be very effective, even in children for whom melatonin did not work (21:05). 

Summary and Q&A

Malow summarizes the presentation, reiterating that many causes and contributors are treatable. She emphasizes identifying sleep problems in autism and their impact on daily function and family dynamics (22:10). Future research directions include extensive treatment studies, randomized controlled trials, more adolescent and adult studies, long-term studies, and attention to co-occurring conditions. 

During the Q&A (24:45), Malow discusses the effect of metabolism on melatonin uptake, research on sleep routines (27:30), sleep hygiene and puberty (32:40), and cases of sudden onset sleep disruption (39:15). She outlines risks, concerns, and common questions around melatonin (43:45) and touches on GI health, depression, and the critical importance of communication (48:11). The speaker provides details on restless leg syndrome, the FISH assessment, and sleep dependency (55:10).

Beth Malow, M.D., discusses the prevalence, causes, and impact of sleep issues in autistic individuals. She explains the connection between core autism presentations, brain function, and sleep and emphasizes the importance of behavioral support strategies. The presenter considers the impact of poor sleep on daily social and emotional functioning for autistic individuals and their families. She touches on evidence-based medical, behavioral, and biological interventions and summarizes the presentation before the Q&A.

Prevalence of sleep issues in autism

Malow describes typical bedtime routines for children and outlines presentation objectives (2:45). She explains that sleep disturbances can impact daytime functioning for the entire family unit (5:00). As of 2017, she continues, parent-report studies show between 53% and 66% of autistic children experience sleep problems (7:25). Studies also reveal a high prevalence of insomnia in autistic children across autism presentations. Insomnia symptoms include resistance to bedtime, sleep anxiety, problems falling asleep and staying asleep, GI discomfort, and much more (8:55). Malow emphasizes that sleep issues are highly treatable when standards of care and evaluation are evidence-based (5:00). 

Causes of sleep issues in autism

Causes of insomnia in all people result from the interaction of biological, medical, and behavioral drivers, many of which overlap. Biological causes include hormonal imbalances (e.g., melatonin), circadian clock factors, overarousal, sensory oversensitivity, anxiety, and ADHD. Medical drivers refer to things like sleep apnea, seizures, GI issues, and medications (10:20). Malow asserts that behavioral factors, such as exercise, caffeine intake, screen time, and parental stress, are the most critical drivers of sleep issues (12:15). She describes how to read data charts for sleep apnea and epilepsy (13:25). 

Arousal dysregulation, or feeling overstimulated, is tied to anxiety, sensory stimulation, and functional GI issues, which are all common features of autism (14:55). Malow explains that dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis occurs in both insomnia and autism and notes that studies of autonomic functions also reveal patterns of overarousal in autistic brain activity (15:13). Therefore, she continues, interventions that target hyperarousal provide opportunity for biomedical goals and observations, especially for autistic individuals (16:44).

Melatonin

The presenter defines melatonin as an endogenous hormone (released at night) that can cross the blood-brain barrier and is critical to circadian rhythm function (17:00). Melatonin supplements are known to help with anxiety, hyperarousal, and sleep-wake cycles. Malow underscores the need to consult a practitioner before adding melatonin to a diet or routine (19:00). 

Impact of sleep on social-emotional development in autism

Core presentations of autism, like difficulties with social interaction and communication, are often exacerbated by poor sleep (19:15). This is true, Malow asserts, whether or not a person is autistic (21:15). She explains that when we are sleep deprived, the amygdala and prefrontal cortex (emotional part of the brain) do not communicate well, which allows our emotions to “go wild” (22:15). Studies have found that fewer hours of sleep predict overall autism score and that co-occurring conditions and adolescent relationships are affected by poor sleep quality (24:03). 

Insomnia interventions

Behavioral approaches are critical to making a difference in sleep, especially for autistic individuals (24:55). Malow outlines the Sleep Habits Questionnaire, The Family Inventory of Sleep Habits (FISH), and polysomnography. She emphasizes sleep hygiene and making sleep observations comfortable and family-friendly (26:08). Components of successful sleep for any person include the amount, time, and regularity of sleep (29:15). She suggests visual schedules and checklists to help with bedtime routines and discusses strategies for sleeping through the night (31:15). Studies show that autistic children of parents receiving sleep education experienced significant improvements in sleep latency (time to fall asleep) and repetitive behaviors (33:30). Malow lists free online tools for parents and caregivers and emphasizes the importance of parent confidence and health (35:00). 

Pharmacological interventions

The speaker asserts that pharmacological treatments are best used only after behavioral interventions have been tried and did not work on their own (35:15). Melatonin is commonly used and is most effective in combination with behavioral strategies (36:25). Malow considers the advantages of prolonged-release Melatonin, noting that no long-term side effects have been identified (37:25). In a prospective study of 24 autistic children, no alterations to reproductive hormones were found. Still, more research needs to be done (38:55). Malow reiterates the need to discuss melatonin use with a care practitioner and combine it with lifestyle changes and behavioral strategies. She summarizes the presentation and highlights future areas of research (39:40). The speaker reiterates that sleep issues are highly treatable before opening the Q&A (40:45).
