F06 — Other mental disorders due to brain damage and dysfunction and to physical disease

Concept, in one sentence

A discrete psychiatric-type symptom picture attributable to a demonstrable organic cause, with clear consciousness and no dementia-level decline.

Decisive boundary cues

• A demonstrated, temporally plausible organic cause -> weighs toward F06.
• Disturbed consciousness -> weighs toward F05 instead.
• An enduring personality change rather than a discrete symptom episode -> weighs toward F07 instead.

Duration/course cue

Follows the course of the underlying physical disease; often improves with its treatment.

Nearest alternatives

F00, F05, F07

Common mistake

Labelling a symptom picture organic simply because a physical illness happens to coexist, without checking for a plausible temporal and causal link.

What evidence actually links this symptom picture to a physical cause, beyond the two simply coexisting?
