Diagnostic Overshadowing


Diagnostic Overshadowing
The Issue
Demand Fair Medical Investigations for Young People with Learning Disabilities, Autism and complex needs.
Stop Diagnostic Overshadowing in the NHS
Petition to improve NHS accountability and ensure equal access to medical investigations
The Issue
Jake Moore is an 18-year-old young man with complex needs who has been repeatedly failed by the healthcare system.
Despite clear, ongoing motor difficulties identified throughout childhood, Jake has never received the full and appropriate medical investigations he deserves.
Instead, his symptoms have too often been dismissed or wrongly attributed to his learning disability.
This is known as diagnostic overshadowing — and it is happening far too often.
What is Diagnostic Overshadowing?
Diagnostic overshadowing occurs when healthcare professionals assume that new or existing symptoms are part of a person’s learning disability or autism, rather than properly investigating them.
This can lead to:
Missed or delayed diagnoses
Lack of treatment
Long-term harm
Inequality in healthcare
Jake has experienced this first-hand.
What Happened to Jake
Motor difficulties were identified in childhood — but never investigated
Multiple services recognised concerns — but failed to refer
He was passed between NHS departments without being seen
After a 65-week wait, he received a 20-minute neurology appointment
No reasonable adjustments were made for his learning disability
No full history was taken
No childhood reports were reviewed
Further investigations were refused
A life-impacting decision was made based on limited information and opinion.
This Isn’t Just About Jake
This is happening to many individuals across England.
People with learning disabilities and complex needs are at higher risk of being dismissed, ignored, or misdiagnosed.
They deserve the same standard of care as everyone else.
What We Are Asking For
We are calling on NHS leaders, regulators, and government to:
Ensure mandatory reasonable adjustments for patients with learning disabilities
Require full clinical history reviews, including childhood reports
Prevent diagnosis based on assumptions or limited assessments
Introduce safeguards to identify and prevent diagnostic overshadowing
Guarantee access to appropriate and timely investigations
Improve accountability across NHS services
Jake's message
Jake does not want compensation.
He does not want to take legal action.
He simply wants:
A fair, thorough investigation — just like any other young person.
And he wants to make sure others don’t go through the same experience.
Take Action
Sign this petition to demand change.
Help ensure that no one is overlooked, dismissed, or denied care because of a label.
Everyone deserves to be heard. Everyone deserves proper medical care.
