A lot of people associate Autism Spectrum Disorders (ASD) with challenges in communication. However, many autistic individuals also have difficulties with both eating and swallowing, known as dysphagia. This article explores the connection between autism and dysphagia, its impact, and ways to help.
The Link Between Autism and Dysphagia
Swallowing is a surprisingly intricate process. Brain imaging studies reveal that not only the brainstem but also various cortical areas play a crucial role in regulating swallowing. This intricate interplay between nerves and muscles highlights the complexity of swallowing disorders and the potential reasons why autism might be linked to dysphagia.
There are several ways autism could disrupt the smooth flow of swallowing. One possibility is orofacial motor dysfunction. This refers to difficulty coordinating the muscles in the face and mouth for chewing and swallowing. Children with autism might have trouble with the precise movements needed to manipulate food in their mouths.
Another factor to consider is sensory processing. Autistic individuals often experience the world differently. Textures, tastes, and smells that most people find unremarkable can be overwhelming or unpleasant for someone with sensory sensitivities. This aversion to certain foods or textures might lead to resistance during mealtimes.
Focus and attention difficulties are also common in autism. A child who is easily distracted during meals might not pay close enough attention to properly chew or swallow their food. This could lead to rushed swallowing or incomplete chewing, increasing the risk of choking or aspiration (food or liquid entering the lungs).
Finally, communication challenges associated with autism can make it difficult for individuals to express discomfort or difficulty swallowing. Without the ability to communicate their needs, they might be unable to signal caregivers if they are experiencing problems, potentially leading to undetected dysphagia.
The Effects of Feeding Disorders on Autistic People
Feeding difficulties are a less-discussed but crucial aspect affecting up to 80% of autistic children, creating a complex web of challenges that extend far beyond mealtimes. Let’s delve deeper into some of the key areas impacted by these feeding problems.
- Nutritional Deficiencies and Gastrointestinal Issues: Selective eating and sensory sensitivities often lead to inadequate intake of essential nutrients. This can trigger gastrointestinal difficulties like constipation, vomiting, diarrhea, and abdominal pain. Chronic discomfort can impede progress in other areas of therapy and daily life.
- Problematic Behaviors at Mealtimes: Efforts to avoid disliked foods manifest as screaming, crying, irritability, aggression, or attempts to escape the table. Children may express distress by turning away, chewing without swallowing, spitting out food, or even vomiting.
- Limited Diet and Growth Concerns: Research shows autistic children consume less of essential food groups compared to their typically developing peers. This restricted diet can lead to deficiencies, impacting growth and development. Studies also suggest food selectivity is unlikely to improve by itself, highlighting the need for early intervention.
Addressing feeding difficulties goes beyond just mealtime struggles. Therapists often encounter children whose challenging behavior might stem from hunger. By ensuring proper nutrition and comfort during meals, we lay the groundwork for better outcomes in occupational, speech, and other therapies.
Helping Autistic People with Dysphagia and Other Feeding Disorders
Unlike traditional dysphagia, which often stems from a physical or neurological cause, autistic individuals may experience a condition called habitual dysphagia. This means they have swallowing difficulties despite no underlying medical explanation.
While symptoms in children might be mild, they can have serious consequences later in life, including digestive issues like gastritis, constipation, and GERD. Here’s a deeper look at habitual dysphagia in autism and how to address it.
Signs and Symptoms
Habitual dysphagia often goes unnoticed in children because the initial symptoms are subtle. However, therapists can identify red flags like tongue thrusting, food texture aversion, rapid eating, and pocketing (storing food in cheeks).
Research suggests that habitual dysphagia can lead to lifelong digestive problems if left untreated. Early intervention by a speech-language pathologist (SLP) is crucial. SLPs can assess swallowing mechanics, observe mealtimes, and identify areas for improvement.
Treatment Strategies
Treatment for habitual dysphagia focuses on retraining swallowing patterns and improving oral motor skills. SLPs might use various techniques, including:
- Oral motor exercises: Strengthening and coordinating the muscles involved in chewing and swallowing.
- Sensory integration therapy: Helping individuals tolerate different textures and tastes.
- Visual cues and prompts: Providing visual aids to guide proper swallowing techniques.
- Positive reinforcement: Rewarding successful attempts and progress made during meals.
Diet Considerations
While some dietary modifications might be necessary to manage digestive issues, addressing the root cause – habitual dysphagia – is essential. SLPs can work with nutritionists to create a safe and effective feeding plan.
Medication Management
Individuals with habitual dysphagia might struggle to swallow medications. SLPs can advise on safe and appropriate strategies for medication administration, ensuring medications are taken effectively and comfortably.
Parental Involvement
Parents and caregivers also play a vital role in supporting children with habitual dysphagia. By collaborating with therapists, parents can create a consistent and supportive environment for successful treatment.
Getting Professional Help
If you suspect your child on the autism spectrum has dysphagia or other feeding difficulties, seeking professional help is crucial. Consider contacting a board-certified ABA therapist specializing in feeding interventions.
