What can I do today?

Small, doable steps for right now, this week, and when to bring in a professional. Educational only — not individualized medical or behavioral advice.

Step 1

In the next 10 minutes

Pause and take three slow breaths together — regulate yourself first.
Reduce sensory load: lower lights, turn off background noise, offer quiet space.
Drop non-essential demands for the next few minutes. Safety and connection first.
Offer a preferred item or activity, or a familiar comfort routine.
Use fewer words. Try a visual, gesture, or written cue instead of talking through it.

Step 2

This week

Track what happens before, during, and after for 3–5 days (ABC notes).
Look for patterns in sleep, hunger, sensory input, and transitions.
Test one small environmental change (lighting, timing, warning before switches).
Introduce or review a visual schedule for the parts of day that are hardest.
Plan a 15-minute connection time daily, without demands, to fill the tank.

Step 3

Questions to ask a professional

Pediatrician or physician

Could a medical issue (pain, reflux, constipation, sleep apnea, allergies) be contributing?
Are there any recent changes in health, medication, or growth we should investigate?
What screenings or referrals would you recommend at this stage?

BCBA or behavior specialist

What might this behavior be communicating, and what function does the data suggest?
What antecedent changes and replacement skills would you prioritize first?
How will we measure progress, and how often will we review the plan together?

Occupational therapist

What sensory patterns are you seeing, and what supports do you recommend?
Which activities of daily living should we target first, and how?
Are there environmental adjustments we can try at home or school?

Executive Function in Adulthood

Executive function (EF) refers to the mental processes that let us plan, start, switch, and finish tasks. Autistic adults show consistent EF differences on both laboratory tasks and daily-living measures (Demetriou et al., 2018).

The most affected areas

Task initiation — knowing what to do is not the same as being able to start.
Cognitive flexibility — switching plans mid-stream costs disproportionate energy.
Working memory during social multitasking.

What research supports

External structure beats internal willpower. Written checklists, visual timers, and body-doubling all show benefit (Pellicano et al., 2017).
Reduce decisions, not tasks. Batch cooking, uniform wardrobes, and templated emails preserve EF for what matters.
Rule out co-occurring ADHD. Stimulant medication, when appropriate, can significantly reduce EF load (Hours et al., 2022).
