Myth: Autism only affects boys; girls don't have autism

Autism in Girls: Missed, Masked, Underdiagnosed

### The Numbers

Diagnosed ratio: 3-4 boys per 1 girl

Estimated true ratio: 2-3 boys per 1 girl (or possibly 1:1 in some studies)

**Girls are significantly underdiagnosed**

### Why Girls Are Missed

1. **Different presentation** (autism still present, but looks different):

- Boys: Obvious special interests (trains, dinosaurs, space), intense focus

- Girls: Special interests blend in (animals, books, fandoms) or are solitary (art, writing)

- Boys: Stimming visible (hand flapping, loud vocalizations)

- Girls: Stimming internal (repetitive thoughts, organizing, checking)

- Boys: Social withdrawal apparent

- Girls: Socially motivated but struggle with nuance (try to fit in, mask exhaustion)

2. **Masking/Camouflaging**:

- Girls often learn to hide autism traits (from observation, survival instinct)

- Copy peers' behavior, suppress stims, force eye contact

- Causes: anxiety, depression, burnout (because masking is exhausting)

- Not visible in early testing → misses diagnosis

3. **Professional bias**:

- Diagnostic criteria developed mostly on boys

- Therapists trained on boy presentation

- "That can't be autism—she has friends" (wrong; autistic girls often have friends)

- Factors in ADHD presentation (girls with ADHD often also autistic, but ADHD diagnosed first)

4. **Comorbid conditions mask autism**:

- Girls with autism often have anxiety, depression, eating disorders

- These get diagnosed & treated; autism misses radar

- Or: "Her anxiety is the problem, not autism"

### Real-World Examples

**Autistic girl**: Has close friend, good grades, organized, chatty in small groups

**Assessment conclusion**: "Not autistic—too social"

**Reality**: Exhausted from masking, anxious, struggling with sensory overload

### Health Consequences of Missed Diagnosis

**Continued masking** → burnout, mental health crisis (often in teens/early 20s)

**No accommodations** → struggles in school/work despite ability

**Shame & confusion** → "Why am I different? What's wrong with me?"

**Delayed support** → misses early intervention benefits

**Girls more likely to** self-harm, attempt suicide (related to unaddressed autism + masking burden)

### How to Recognize Autism in Girls

Intense but "acceptable" interests (writing, art, animals, books, role-playing)

Few but close friendships (vs. many friends)

Anxiety, perfectionism

Difficulty with unstructured time (recess, free periods)

Sensory sensitivities (tags, food textures, loud sounds)

Routines and difficulty with changes

Exhaustion at end of school day

Internal stimming (repetitive thoughts, organizing, arranging)

### If You Think Your Daughter Is Autistic

**Seek evaluation from autism specialist** (not just general pediatrician)

**Request specifically** for girl/female-pattern autism assessment

**Bring specific examples**: Sensory issues, social fatigue, detailed interests, anxiety

**Consider self-report** from daughter (older girls can articulate experience)

**Expect pushback**: Some clinicians underdiagnose girls; get second opinion if needed

### Positive Aspects

Autistic girls/women often have:

- Strong empathy and deep relationships

- Creative abilities

- Persistence and attention to detail

- Justice orientation

- Loyalty to friends and values

### Moving Forward

If your daughter is autistic:

**Early diagnosis**: Access to support, accommodations, understanding

**Reduce masking pressure**: Create safe spaces where she can be herself

**Teach self-advocacy**: "Your autism is not a flaw; here's how to ask for what you need"

**Monitor mental health**: Watch for depression, anxiety, eating disorders (more common in autistic girls)

**Build skills, not normalcy**: Support her unique strengths
