Is autism different in women?

Autism in women and girls is significantly underdiagnosed — the true ratio is estimated to be close to 3:2 (male:female), but clinical diagnosis detects ratios of 4:1 or higher. The central reason: diagnostic criteria were developed mainly from studies of boys.

Differences often observed in the female profile:

More intense masking: autistic girls tend to be more socially motivated and develop masking (camouflaging autistic traits) more intensely and effectively, which delays diagnosis but comes at an enormous cost in exhaustion and mental health.

More socially acceptable interests: special interests in animals, actors or singers, TV shows, or reading do not stand out the way stereotypically male interests do (trains, numbers, and so on).

More internalizing difficulties: anxiety, depression, and other internalizing problems are more common in autistic women. They often receive those diagnoses first, without the underlying autism ever being identified.

Late diagnosis — in adolescence, adulthood, or midlife — is much more common in women. Many describe relief and validation upon receiving the diagnosis, but also grief over decades spent without the right support and understanding.
