We propose that a mention of acute confusional state may be included in the "comments" section of "7.3.5-syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL)," when ICHD-3 diagnostic criteria will be updated. Moreover, we speculate that intracranial hypertension may play a role in the pathogenesis of the acute confusional state associated to HaNDL syndrome. Larger case series are needed to evaluate this hypothesis.
