CLINICAL ATLAS · AREA 05

Sleep / state / fatigue

Open the exact information count, clinical terms, source boundaries, and next measurement for this area. Counts describe information availability—not prevalence.

HOW TO READ THE COUNTSOne key applies to all 15 areas.Each area places all 63 connected people into one mutually exclusive category. These groups describe the information available; they are not prevalence estimates.

A finding is reported
At least one feature is reported, without an explicitly normal or uncertain item in the same area.
A finding plus normal or uncertain information
A reported feature appears alongside an explicitly normal result or an unresolved observation.
Only explicitly normal results
The available information records a normal or negative result without a reported feature in the area.
Only uncertain information
An observation remains unresolved and no confirmed feature is recorded in the area.
Area not addressed
The available information does not answer this broad area; this is not a negative result.
AREA 05 / 15Neurocognitive & state · State regulation

Information available for Sleep / state / fatigue

Can the nervous system enter, sustain, and exit physiological states reliably?

Sleep onset and architecture, awakening, daytime fatigue, state-dependent access, recovery windows, paradoxical alerting, and within-day variability.

41 with information + 22 not addressed = 63. For 7 people, at least one item in this area is supported by an original clinical or laboratory source addressing the area.

WHAT THE INFORMATION SHOWS

Information available from connected people includes fragmented or short sleep, awakening-linked change, failed sleep staging in one study, normal staged sleep in another, and airway or sleep-deprivation burden.

HOW TO READ IT

Sleep duration, architecture, airway, nocturnal events, circadian state, medication, and daytime access must be separated.

NEXT MEASUREMENT

Pair sleep diary or actigraphy with iron and airway review, medication timing, event logs, and polysomnography or EEG when the clinical question supports it.
