Improve Focus With Behavioral Tools & Medication for ADHD | Dr. John Kruse
Dr. John Kruse, a psychiatrist specializing in ADHD treatment, shares valuable insights into managing this complex disorder. He discusses the various medications available, weighing their benefits against potential risks. The conversation covers the significant impact of behavioral strategies, such as maintaining consistent sleep schedules and incorporating exercise. Dr. Kruse also highlights the effects of genetics and environment on ADHD diagnoses, as well as the importance of finding the right career paths for individuals with ADHD to enhance focus and productivity.

What is ADHD — a quick reality check
2:41 – 4:56
ADHD = 18 symptoms (9 inattentive, 9 hyperactive/impulsive).
Adults need ≥5 symptoms and those behaviors must cause dysfunction across multiple life areas (work, home, social).
It's not just being forgetful — it's normal behaviors to an excessive degree, which fuels stigma.
ADHD often persists into adulthood.
"Most adults fluctuate in time with the severity of their ADHD symptoms."
— John Kruse
Nature + Nurture: why ADHD varies with environment
6:44 – 9:22
Heritability of ADHD ≈ 0.8 — very high. But environment shapes expression: structure matters.
During COVID, diagnoses and stimulant prescriptions rose as daily structure fell and demands rose (kids, remote work).
ADHD brains are more interest-driven and need optimal external structure to perform.
"The ADHD brain is less able to provide the structure it needs, so it's more reliant on an optimal structure in the outside world."

4 Essential daily pillars for focus
34:52 – 43:36
4 pillars to anchor attention:
- Sleep (regular bedtime/wake time > just 8 hrs)
- Eating (regular meals — prevents zoning out)
- Exercise/movement
- Me-time/relaxation (meditation, cyclic sighing)
Try 5 minutes cyclic sighing before bed — it reduces arousal and improves sleep continuity.
"The timing of your sleep is every bit as important as the duration."
— John Kruse
Medications — what works, what to watch
1:05:54 – 1:10:14
Quick guide:
- Amphetamines (Adderall, Vyvanse) = most effective symptom reduction. Vyvanse is a slow‑release prodrug (smoother profile).
- Methylphenidate (Ritalin) = helpful but often less potent.
- Non‑stimulants (Wellbutrin, Strattera, modafinil, guanfacine) = options for some.
Rare risk: amphetamine‑induced psychosis (~1/500). Check personal & family psychosis history.
"One out of 500 people... it's uncommon, but this is a really bad condition."
— John Kruse
Lifestyle + substances: practical rules
1:37:50 – 1:38:50
Practical substance rules:
- Caffeine: helps many — avoid after ~2pm; dosing varies by drink.
- Nicotine: improves some executive functions but carries health/addiction risks.
- High‑THC cannabis: linked to poorer motivation and higher psychosis risk — consider stopping before stimulant trials.
- Fish oil: target ~1,000 mg EPA/day (can double if tolerating).
"Daily marijuana use: lower motivation, poor organization… why would anyone with ADHD want that?"
— John Kruse
Hyperfocus, timing & time perception
27:54 – 31:41
ADHD paradox: hyperfocus (deep flow) exists — but control and timing are impaired.
Lab tests show people with ADHD are “consistently inconsistent” estimating elapsed time. They often know now vs not-now but don’t track time across the day.
Tools: time‑blocking, external reminders, morning bright light to align circadian rhythm.
"Hyperfocus is exactly a flow state."
