Late Diagnosis

Late diagnosis is when someone realises — or is formally diagnosed — as neurodivergent later in life. Often, this comes after years of adapting, masking, or feeling “off” without knowing why.

It might come through:

• Seeing yourself in someone else’s diagnosis
• Burnout that feels different from general stress
• Support groups, social media, or personal research
• A formal assessment in adulthood, sometimes prompted by parenting or therapy

Many people who are diagnosed late grew up thinking their struggles were personal failings — not signs of a different way of thinking, sensing, or processing.

That moment of recognition can bring a lot of emotions:

• Relief (“It all makes sense now”)
• Grief (“Why didn’t anyone notice?”)
• Anger (“I could’ve had support sooner”)
• Clarity (“Now I know what I need”)

Some people choose not to seek a formal diagnosis — and that’s valid. For many, self-diagnosis is enough, especially when it leads to self-understanding, connection, or better coping strategies.

That said, formal diagnosis can bring benefits:

• Legal recognition or accommodations (e.g. at work or university)
• Access to therapies, support services, or financial help
• Clarity during family planning or health decisions
• A sense of closure — being seen and heard by someone else

Late diagnosis isn’t a failure. It’s not “too late.” It’s often a powerful act of self-trust — a reminder that it’s okay to finally put the pieces together and say, “This is who I am — and it makes sense now.”
