Trauma-Informed Care for Neuroatypical Individuals: Understanding Sensory Processing and Preventing Re-victimization

This presentation by Dr. Donnelly Snipes delves into trauma-informed care specifically for neuroatypical individuals, with a particular focus on those who are pre-verbal or non-verbal and thus unable to articulate their needs. It defines neuroatypicality broadly, extending beyond autism spectrum disorders to include conditions like schizophrenia, fetal alcohol spectrum disorders, ADHD, and OCD, and even hypothesizes a link to personality disorders. The core argument is that neuroatypical individuals experience the world profoundly differently, leading to common, seemingly benign parenting or business practices becoming traumatic due to sensory processing differences.\n\nThe discussion extensively explores sensory abnormalities, categorizing them into hyper-responsivity (e.g., heightened pain, sensory overload) and hypo-responsivity (e.g., vulnerability to injury due to lack of pain perception, under-stimulation). These differences can make everyday experiences overwhelming or underwhelming, triggering the HPA axis and creating a chronic state of fear or distress. The concept of \"sensory gating abnormalities\" is introduced, explaining how neuroatypical brains may struggle to filter out irrelevant stimuli, leading to constant bombardment and an inability to habituate to repeated inputs, as seen in conditions like ADHD, OCD, schizophrenia, and PTSD.\n\nThe long-term consequences of chronic trauma and sensory dysregulation are highlighted, including HPA axis dysfunction, persistent emotional dysregulation, and the development of \"flat and furious\" response patterns. The presentation draws a parallel to Marsha Linehan's work on invalidating environments, suggesting that a lack of understanding from caregivers can exacerbate these issues and contribute to the development of personality disorder symptoms. Cognitive impacts such as difficulty processing stimuli, school failure, and neurotoxic effects of elevated glutamate on developing brains (leading to decreased white/gray matter and impaired executive functioning) are also discussed.\n\nInterpersonally, sensory challenges can lead to social withdrawal, seemingly defiant behaviors (e.g., refusing baths due to tactile sensitivities), and even unintentional neglect or abuse from caregivers who misunderstand the child's reactions. The presentation emphasizes the importance of re-interpreting "problem behaviors" as communication of distress and adapting environments to prevent re-victimization. It also touches on specific challenges in schizophrenia, such as impaired visual and tactile processing, difficulty recognizing fragmented objects, and the impact of backward masking on memory consolidation, underscoring the pervasive nature of sensory differences across various neuroatypical conditions.

"people who are neuroatypical do experience the world differently"

"neuroatypical is a newer term that's used to describe individuals of who have developmental in a like developmental intellectual and cognitive disabilities that are not typical"

"personality disorders may also represent a behavioral adaptation of individuals who are neuroatypical but were not able to communicate that"

"when people are traumatized they feel or experience trauma they have a lack of personal power and they have a sense of a loss of safety"

"when people are chronically exposed to trauma stressors pain threats whatever whatever it looks like to that person it results in a dysfunction in that threat response system in that HPA axis"

"if people are repeatedly traumatized as infants as toddlers then they are in that framework of the flat and the Furious they're in that framework of experiencing regularly experiencing emotional dysregulation from childhood"

"sensory gating abnormalities... Gatekeepers that filter out stimuli they say that's not important that's not important that's not important we'll let that one through people who are neuroatypical may not have a the ability to filter out stimuli"

"people with sensory gating difficulties and PTSD demonstrate exaggerated responses to stimuli and reduced habituation"

"backward masking involves presenting one stimulus a masking stimulus immediately after a brief Target stimulus resulting in a failure to consciously perceive the first stimulus"

"abnormal perception arises from abnormal sensory predictions"

"people are basically fragmented when you cut off their nose and mouth from being able to be seen"

"when the child is not able to get their needs met that is the definition of neglect"
