Are you or your child wondering about autism? At Brookside Therapy & Assessments, we offer comprehensive autism assessments for children, teens, and adults. Whether you’re seeking a child autism diagnosis, exploring a possible adult autism assessment, or supporting a teenager who may be neurodivergent, our team provides clear, respectful, and affirming evaluations.

Why Choose Our Autism Diagnostic Services?

We provide:

• Autism assessments for adults, teens, and children

• In-depth evaluations using comprehensive diagnostic tools

• An affirming, neurodiversity-positive approach

• Supportive feedback and customized, comprehensive recommendations

• Formal reports for school, workplace, or personal understanding

Our assessments are ideal for people who may have been overlooked, misdiagnosed, or are seeking answers later in life.

Autism Diagnosis: What’s Involved?

Our assessments include:

• Clinical interviews with the individual (and parents or someone who knows the client well, when applicable)

• Developmental and behavioural history

• Standardized tools (e.g., ADOS-2 for child assessments only, MIGDAS-2, RAADS-R, etc.)

• Screening for ADHD, anxiety, trauma, and other overlapping concerns

• A clear diagnosis (if criteria are met) and comprehensive written report

• A feedback session with a licensed psychologist

We tailor each evaluation to suit the individual’s age, communication style, and life context.

Who We Help

Our licensed psychologists diagnose autism in:

• Children aged 6+ (especially those who are gifted, sensitive, or misunderstood)
