    Here we report the case of an 86-year-old woman with advanced dementia addressed to our service for routinary ECG Holter Monitoring (EHM) for bradycardia in AV block type I. Several day-time episodes of fall-asleep while sitting had been previously reported by the nurse and generally attributed to the dementia itself, without taking into consideration the hypothesis of an AV block. The EHM reading reported several and often subsequent pauses (561), many of them critical, the longest lasting 15,9 s with no changes in clinical condition of the patient. The results of the EHM were reported to the physicians in charge for the patient and subsequently the woman was referred to the arrhythmology unit for pace-maker device implantation. Generalizing our experience, we suggest that advanced dementia, often associated with episodes of fall-asleep, could mask a conduction disturbance causing critical pauses with syncope; therefore we suggest screening those patients for possible arrhythmic disorders. Finally, we remark that in our patient the pauses weren’t associated with a worsening of the patient as seen in the follow-up, and this fact supports the hypothesis that vascular dementia could increase cerebral ischaemic tolerance

    Multiple system atrophy (MSA) is a sporadic, neurodegenerative disorder, clinically characterized by parkinsonian, autonomic, cerebellar and pyramidal signs. We describe two patients showing different presentations of the same disease. The patient on case 1 presents features of MSA-C or olivopontocerebellar atrophy with the pontine "cross sign" on brain MRI. The second case reports a patient presenting MSA-P or striatonigral degeneration and the brain MRI shows lenticular nucleus sign alteration. We think that brain MRI might increase the accuracy diagnostic of MSA.<br>A atrofia de múltiplos sistemas (AMS) é uma doença neurodegenerativa esporádica caracterizada clinicamente por diferentes combinações de sinais parkinsonianos, autonômicos, cerebelares e piramidais. Descrevemos dois pacientes apresentando diferentes formas clínicas da mesma afecção. O caso 1 tem características da AMS-C ou atrofia olivopontocerebelar, apresentando na ressonância magnética (RM) o "sinal da cruz" na ponte. Já o caso 2 tem AMS-P ou degeneração nigro-estriatal, a RM mostra alteração do sinal no núcleo lentiforme entre outras alterações. Acreditamos que a RM cerebral possa contribuir para o melhor diagnóstico da AMS
