Depression affects about 7% of all people—but for people with autism, this jumps to about 40%. The link between autism spectrum disorder (ASD) and depression is very important but often missed by doctors. This affects how well someone lives, how they function, and their long-term health.

This guide explores how autism and depression overlap, offering helpful insights for people with autism, their families, and the professionals who work with them.

How Autism and Depression Are Connected: What Studies Show

The link between autism and depression is stronger than many people know:

  • Adults with autism are 4 times more likely to have depression than people without autism
  • 70-80% of autistic children will have some mental health issue during their lifetime, with depression being very common
  • Suicide risk is 7-10 times higher for people with autism
  • Only 25% of autistic people with depression get the right treatment
  • Women and girls with autism have higher rates of depression (63% compared to 37% of men and boys with autism)

Why Is Depression So Common in Autism?

Several things make depression more likely for people with autism:

Brain and Body Factors:

  • Shared genes that affect both autism and depression
  • Differences in brain chemicals that control mood
  • Different stress responses and stronger emotional reactions

Social and Environmental Factors:

  • Challenges making and keeping friends
  • More bullying and negative social experiences (70% of young people with autism report being bullied)
  • Sensitivity to sounds, lights, and textures causing ongoing stress
  • Hiding autism traits to "fit in" (which makes depression 2.5× more likely)

Growing Up Factors:

  • Becoming more aware of being different during teen years
  • More social pressure as you get older
  • Challenges becoming independent as an adult

Spotting Depression in Autism: It Can Look Different

Depression can show up differently in people with autism, making it hard to spot:

Common Depression Signs

  • Feeling sad most of the time
  • Losing interest in things you used to enjoy
  • Changes in sleep and eating
  • Feeling tired all the time
  • Feeling worthless or very guilty
  • Trouble focusing
  • Thoughts about death or suicide

How Depression May Look Different in Autism

  • Pulling away more from already limited social activities
  • More repetitive behaviors or deeper focus on special interests
  • Changes in sensitivity to sounds, lights, or touch
  • More irritability, agitation, or meltdowns instead of saying "I'm sad"
  • Loss of skills or ability to do daily tasks
  • Changes in routines (either becoming more strict or dropping them)
  • Changes in how someone communicates

Important Facts:

  • 35% of autistic people with depression don't say they feel sad
  • 45% show depression mainly through changes in behavior
  • 52% of depression cases in autism are first thought to be "just autism"

Challenges in Diagnosing Depression in Autism
