Sleep
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
I want to evaluate whether broken or unrefreshing sleep is driving my brain fog and how to separate that from sleep apnea, circadian drift, anxiety, or metabolic overlap.
What would weaken it
- -No relationship between sleep quality and next-day cognition.
- -Rare good nights don't improve anything and bad nights don't make it worse.
- -The pattern is better explained by sleep apnea, depression, meds, or another cause rather than ordinary sleep disruption.
Key points to communicate
- •I want to know whether this is simple sleep disruption, circadian trouble, insomnia, or hidden sleep apnea.
- •Please separate sleep debt from depression, anxiety, stimulant use, and medication effects.
- •If sleep is central, I want the most useful first intervention or test rather than generic sleep-hygiene advice.
Bring this to the visit
- •A 2-week sleep diary: bedtime, wake time, time to fall asleep, awakenings, sleep quality.
- •Any sleep tracker data (Oura, Apple Watch, Fitbit) if available.
- •Caffeine and alcohol intake log with timing relative to sleep.
- •Medication list including anything taken for sleep.
Useful screening structure
- -Epworth Sleepiness Scale for daytime sleepiness quantification.
- -PSQI (Pittsburgh Sleep Quality Index) for structured sleep quality assessment.
- -STOP-BANG to screen for sleep apnea if snoring, witnessed apneas, or obesity are present.
Tests and measurements to discuss
Sleep diary + PSQI review
What this helps clarify: This is here to make sure the story is not being driven by sleep-disordered breathing or chronic sleep disruption that could mimic or amplify the primary cognitive pattern.
Epworth Sleepiness Scale
What this helps clarify: This is here to make sure the story is not being driven by sleep-disordered breathing or chronic sleep disruption that could mimic or amplify the primary cognitive pattern.
Sleep apnea screening or sleep study
What this helps clarify: Overnight polysomnography explainer framed around the patient-facing 'sleep study' language most people actually search.
Range context
Sleep report
How to use the result
Ask whether the goal is to rule in sleep apnea, UARS, or another sleep-disruption pattern.
Actigraphy if timing drift is part of the story
What this helps clarify: Wrist-worn sleep tracker - assesses circadian patterns
Range context
7+ days tracking
How to use the result
Save the result with date and symptoms from the same week.
CBT-I referral
Sleep Diary, PSQI, and ESS Review
Bring a short sleep diary and, if possible, a PSQI and Epworth Sleepiness Scale score. That gives the visit more signal than saying you feel tired.
What this helps clarify: This is here to make sure the story is not being driven by sleep-disordered breathing or chronic sleep disruption that could mimic or amplify the primary cognitive pattern.
Ferritin with iron studies, TSH, and fasting glucose
Check ferritin with iron studies, thyroid, and glucose markers when the story includes restless legs, 3-4am waking, post-meal crashes, or other overlap clues.
What this helps clarify: Higher fasting glucose impairs executive function
Range context
70–85 mg/dL (optimal)
How to use the result
Save the result with date and symptoms from the same week.
Actigraphy or CBT-I Referral
Actigraphy can help document sleep timing patterns, and CBT-I remains first-line for chronic insomnia when apnea isn't the main story.
What this helps clarify: Wrist-worn sleep tracker - assesses circadian patterns
Range context
7+ days tracking
How to use the result
Save the result with date and symptoms from the same week.
Questions to ask directly
- •Is my fog from insufficient sleep quantity, poor sleep quality, or a sleep disorder?
- •Should I get a sleep study to rule out sleep apnea or other sleep pathology?
- •Is my current sleep medication helping or making sleep architecture worse?
- •What evidence-based approach should I try first: CBT-I, sleep hygiene, or medication?
Functional impact snapshot
- -Rate fog severity against sleep duration and quality from the previous night.
- -Track whether consistent sleep schedule (same wake time daily) improves function over 2 weeks.
- -Note whether caffeine use patterns are masking an underlying sleep deficit.
Escalate instead of self-managing if
- •Severe daytime sleepiness causing safety concerns: falling asleep while driving or at work.
- •Witnessed apneas or severe snoring suggesting undiagnosed sleep apnea.
- •Cataplexy, sleep paralysis, or hypnagogic hallucinations suggesting narcolepsy.
