The Dementia with Lewy Bodies (DLB) Consortium has refined its recommendations about the clinical and pathologic diagnosis of DLB, updating the previous report, which has been in widespread use for the last decade.

- Paradoxical insomnia (sleep-state misperception): Insomnia characterized by a marked mismatch between the patients description of sleep duration and objective polysomnographic findings Continue reading
