What Is ?

  • is a neurological and developmental difference
  • It is naturally occurring
  • It is not a disease 😷
  • It can’t be cured
  • It has always existed



Autistic People Differ

“If you have met one autistic person
you have met one autistic person.” [1]

— Dr. Stephen Shore ( advocate)

Why Is This Important Now?

  • The “Graying” of the population globally.[2]

  • The first generation diagnosed as children are now entering middle age.[3]

  • The massive, previously unidentified group of people aged 50-80+.[4]

  • A critical lack of research and services for autistic seniors.[5]

The Timeline of Invisibility

Why didn’t they get diagnosed 40 years ago?

autism-timeline.jpg

  • 1943-1944: Kanner & Asperger define the condition (mostly in children).
  • 1980 (DSM-III): “Infantile ” enters the DSM. Strict criteria.
  • 1994 (DSM-IV): Asperger’s Syndrome added. The beginning of broader recognition.
  • 2013 (DSM-5): ASD becomes a spectrum; allows for adult diagnosis more easily.

“We aren’t part of an epidemic.
We are part of an awakening.”

— Autism-101

ASD Support Levels

  • Level 1 - requires support
  • Level 2 - requires substantial support
  • Level 3 - requires very substantial support

First Person Diagnosed in U.S.

Donald Triplett - was diagnosed by Leo Kanner in 1943 donald-triplett.png

Donald Triplett

  • Born: Forest, Mississippi in 1933.
  • College: he graduated with a bachelor’s degree in mathematics and French.
  • American Banker: he worked for 65 years at a local bank.
  • Music: he had perfect pitch.
  • Savant: he could do rapid mental multiplication.
  • Book: featured in the book, In a Different Key, later adopted into a documentary.

Who Are “Older Autistic Adults”?

Today, we are focusing on those 50+, but specifically two groups:

  • Diagnosed early: now aging.
  • “Lost Generation”: diagnosed late in life, or still undiagnosed.

Why Were They Missed?

  • Diagnostic criteria historically focused on young, white males with high support needs.[6]
  • Masking or Camouflaging to survive education and employment.
  • Traits attributed to other things: “quirky,” “shy,” “difficult,” or misdiagnosed with personality disorders/anxiety.

What Triggers a Late Diagnosis?

Often, a life event drastically alters the person’s capacity to cope:

  • Burnout: Decades of masking finally depletes energy reserves.
  • Hormonal Shifts: Perimenopause and menopause can intensify sensory/executive function struggles.
  • Major Transitions: Retirement, becoming an empty nester, or loss of a spouse removes stabilizing routines.
  • The “Genetic Mirror”: Seeing their own traits while their child or grandchild is being assessed.

The Diagnostic Journey

As detailed in books like Lost & Now Found [7] , diagnosis is complex:

Relief & Validation

"I'm not broken; I'm Autistic. There is a name for this."

Grief & Anger

Mourning lost opportunities and decades of struggle without support.

Re-evaluation

Reviewing one's entire life history through a new lens.

Case Study: “Susan” (Age 64)

  • Background: Retired librarian. Always called “shy” and “rigid.”
  • The Trigger: Husband passed away 2 years ago. The loss of his support (handling bills, driving, social buffer) caused a collapse.
  • The Misdiagnosis: Diagnosed with Treatment-Resistant Depression and Early Onset Dementia due to “confusion” (which was actually brain fog and burnout).
  • The Realization: Read a memoir by an autistic woman and recognized herself.

and Intellectual Disability (IDD)

  • Overlap: A significant portion of autistic adults also have a diagnosis of Intellectual Disability (30-40%).[8]
  • Complexity: Aging impacts functional skills differently when neurodivergence and IDD co-occur.[9]
  • Support Needs: High support needs may shift from educational/vocational to clinical and residential as the person ages.[10]

The DS-ASD Profile

  • Down Syndrome and (DS-ASD) Individuals with Down Syndrome have a significantly higher prevalence of than the general population.[11]
  • Unique Presentation: Social-communication challenges may be more pronounced than in peers with Down Syndrome alone.[12]
  • Organizational Insight: Care protocols must be tailored to both the genetic profile and the autistic sensory profile.[13]

APP Gene On Chromosome 21

Alzheimer’s and Dementia Risks

  • Heightened Risk: Autistic adults with IDD have nearly 3 times the risk of early-onset Alzheimer’s compared to non-autistic peers.[14]
  • Down Syndrome Link: Due to the APP gene on chromosome 21, nearly all adults with Down Syndrome exhibit Alzheimer’s pathology by age 40.[15]
  • Diagnostic Overshadowing: New dementia symptoms are often wrongly attributed to “just their ” or “typical IDD behavior”.[16]

Co-occuring Conditions

  • Will likely have other issues
  • Ex. ADHD may occur in 40% or more of autistic people [17] autism-and-comorbidities.jpg

Sensory Differences

“Processing everyday sensory information can be difficult for autistic people. Any of their senses may be over- or under-sensitive, or both, at different times.” [18]

— NAS

Sensory Profiles

  • Unique to individual
  • Hyposensitive, hypersensitive, or both
  • Can change day to day
  • Are well outside the normal ranges
  • Impacts what we like to do sensory-profile.png

Do Sensory Issues “Mellow” With Age?

Short Answer: No. They often become harder to manage.

  • Older autistic adults report lower ability to “cope” with sensory input. The energy used to “mask” or “push through” in their 30s is gone.[19]
  • Age-related hearing/vision loss increases cognitive load. The brain works harder to interpret data, leading to faster overload.[19]
  • After age 40, the autistic nervous system may regulate stress less efficiently, making sensory triggers feel more physically painful.[19]

The “Double Whammy”

Aging and interact bidirectionally:

  • Aging processes: Cognitive slowing and physical decline can exacerbate autistic traits like sensory sensitivity and executive dysfunction.[19]
  • Dementia Interaction: Early signs of dementia may first appear as a sudden loss of “coping skills” or an increase in sensory meltdowns.[20]

Diagnostic Overshadowing

  • The Barrier: Clinicians may ignore new health issues (like pain or cognitive decline) because they focus only on the developmental disability.[21]
  • Communication: Non-speaking or minimally-verbal adults may express pain or dementia-related confusion through “challenging behaviors”.[22]
  • Organizational Task: Staff must be trained to look for changes in baseline behavior as medical indicators.

Healthcare Barriers

  • Communication Mismatches: Difficulty describing pain accurately; doctors misinterpreting flat affect or direct/blunt communication as non-compliance.[23]
  • Sensory Overload in Clinics: Bright lights, waiting rooms, and physical exams can lead to care avoidance.
  • Co-occurring Conditions: Higher rates of anxiety, depression, GI issues, and sleep disorders often complicate geriatric care.[24]

Sensory and Cognitive Shifts

  • Sensory: Natural age-related hearing/vision loss combined with autistic sensory processing differences can be overwhelming and disorienting.
  • Executive Function: Aging impacts working memory and processing speed. For an autistic brain already working hard to organize, this can lead to significant functional decline quickly.
  • Burnout Recovery: Bouncing back from sensory or social overload takes significantly longer at 60 than at 30.

Shrinking Support Networks

  • Loss of “Buffers”: Many older autistics relied heavily on parents or a spouse to navigate the social world. Losing them is catastrophic.
  • The “Group Home” Fear: Intense fear of losing independence and ending up in communal senior living, which is rarely sensory-friendly.
  • Financial Vulnerability: Due to lifetime underemployment (common in the lost generation), financial resources for aging may be scarce.

“Autistic Advantages” in Aging

Many older autistic adults possess unique resilience factors:

  • Solitude as Strength: Often better equipped to handle alone time than neurotypical peers.
  • Passionate Interests: “Special Interests” provide deep engagement, cognitive protection, and joy.
  • Non-Conformity: Less pressure to keep up with societal expectations of “how to act”” at 50+“.

Organizational Supports: Sensory Audits

  • Evaluating the Environment: for Dementia-Capable Care.
  • Visual: Reduce flickering fluorescent lights and high-contrast patterns that cause disorientation.
  • Auditory: Identify and mitigate “background” hums (HVAC, machines) that increase cognitive load.
  • Tactile: Ensure clothing and bedding textures remain consistent to prevent sensory-driven distress.

Communication Protocols

  • Direct and Literal: Avoid metaphors or vague instructions; autistic people with dementia need “processing time”.
  • Visual Aids: Use schedules and pictures to reduce the load on working memory.
  • Stabilization: Routine is a clinical tool. Predictable environments reduce the anxiety associated with cognitive decline.

Moving Forward: Neuro-Affirming Care

  • Preserving Energy: Unmasking and sensory aids (headphones, stimming) are energy-conservation tools for seniors.
  • “Nothing About Us Without Us”: Even those with advanced dementia or IDD should have their preferences and sensory comfort prioritized.
